Referring to FIG. 2A, in one or more embodiments, system 200 can comprise media content server 202 communicatively coupled to base station 206 over communication network 204. Further, the system 200 can comprise communication device 208 associated with user 212 and communication device 210 associated with user 214. Each communication device 208 and communication device 210 can be communicatively coupled with base station 206 over a cellular communication network via cellular communication link 216 and cellular communication link 218, respectively. In addition, communication device 208 can be communicatively coupled to communication device 210 over a device-to-device (D2D) communication link 219. In some embodiments, user 217 can provide media content (e.g., voice call, video call, textual message, etc.) utilizing communication device 215 destined for communication device 210 over communication network 204 and base station 206. In other embodiments, communication device 215 can be communicatively coupled to base station 206 over a cellular communication link and any media content from communication device 215 can be provided to the base station 206 over the cellular communication link. In further embodiments, portions of system 200 can be part of a first responder communication network.
In one or more embodiments, the communication network 204 can comprise one or more wireless communication networks, one or more wired communication networks, or a combination thereof. Further, the media content server 202 can comprise one server or multiple servers in one location or spanning multiple locations, a virtual server, multiple virtual servers in one location or spanning multiple locations, one or more cloud servers, or a combination thereof. Each of communication device 208, communication device 210, and communication device 215 can comprise a mobile phone, mobile device, tablet computer, laptop computer, Internet of Things (IoT) device, wearable device, smartwatch, vehicle communication device, augmented reality device, virtual reality device, or combination thereof. Also, the D2D communication link 219 can comprise a radio frequency (RF) communication link. Further, the D2D communication link 219 can utilize a peer-to-peer communication protocol (e.g., BlueTooth™), proximity service protocol (e.g., PC5 Interface), or some other communication protocol. In some embodiments, the proximity services protocol can be implemented by communication device 208, communication device 210, and/or communication device 215.
In one or more embodiments, it may be more efficient for a base station 206 to provide data, information, or media content obtained from media content server 202 or communication device 215 over communication network 204 destined for communication device 210 via communication device 208 over cellular communication link 216 and D2D communication link 219 rather than over cellular communication link 218 (e.g., cellular communication link 218 may be congested). Further, in one or more embodiments, communication device 208 can detect communication device 210 is in its proximity. This can include communication device 208 determining a distance between the communication device 208 and communication device 210 and determining the distance is less than a proximity threshold. The distance can be determined by detecting an amount of power from a signal received from communication device 210. For example, communication device 208 receives a signal from communication device 210 at a certain dBm level. The communication device 208 can look up a table in its memory or query a database that the certain dBm level can indicate that the communication device 210 is about 90 feet from communication device 208m which can be within a proximity threshold (e.g., 100 feet). Further, communication device 208 can establish a D2D communication link 219 with communication device 210. This can include utilizing a proximity services protocol over the D2D communication link 219 to generate a PC5 interface. Further, the communication device 208 can set a proximity services flag within the proximities services protocol. In addition, the communication device 208 can notify the base station 206 over cellular communication link 216 that indicates that setting of the proximity services flag and/or that a D2D communication link 219 has been established between communication device 208 and communication device 210 (e.g., the value of the proximity services flag can be set to 1 in proximity service protocol signaling indicating the establishment of D2D communication link 219). Once the base station is notified that a D2D communication link 219 has been established between communication device 208 and communication device 210, the base station can provide media content (or another data or information) destined for communication device 210 to communication device 208 over cellular communication link 216. Further, the communication device 208 can obtain media content from base station 206 over cellular communication link 216 and can provide the media content to communication device 210 over the D2D communication link 219.
Referring to FIG. 2B, in one or more embodiments, system 200a can include cellular communication link 216a, cellular communication link 218a, and D2D communication link 219a, each experiencing a different network condition. Network conditions can include, but are not limited to, bandwidth congestion, interference, noise, fading, latency, jitter, or any other network condition. Further, the base station 206 can detect a network condition associated with cellular communication link 218a (e.g., congestion). In addition, the base station 206 can determine the network condition does not satisfy a network condition threshold (e.g., the number of communication devices over a portion of a cellular network, the amount bandwidth used by the number of communication devices, etc.). Also, the base station 206 can send an indication to communication device 208 to provide the media content to communication device 210. Such an indication can be a message, the setting of a flag in the proximity services protocol, or any other notification between the base station to communication device 208. Further, the communication device 208 can obtain the media content from base station 206. In addition, the communication device 208 can provide the media content to communication device 210 in response to receiving the indication from the base station.
Referring to FIG. 2C, in one or more embodiments, system 200b can include communication device 208 communicatively coupled to base station 206 over cellular communication link 216, but communication device 210 is not communicatively coupled to base station 206 over any cellular communication link. This can be due to communication device 210 has roamed out of cellular network coverage of base station 206. Thus, in such embodiments the D2D communication link 219 can be operating in a network relay mode. That is, the base station 206 can obtain media content (from either media content server 202 or communication device 215) for communication device 210. The base station 206 detects that communication device 210 is not communicatively coupled to base station 206, but the base station detects that communication device 210 is communicatively coupled to communication device 208 over D2D communication link 219 in response to receiving a notification of the D2D communication link 219 from communication device 208. Further, the base station 206 can send an indication to communication device 208 to provide the media content to communication device 210. In addition, the communication device 208 can obtain the media content from the base station 206 over cellular communication link 216 and the communication device 208 can provide the media content to communication device 210 over D2D communication link 219 in response to receiving the indication from base station 206.

Further, the communication device 208 can establish a D2D communication link 219c to communication device 210 through a WiFi communication network 220. Thus, in such embodiments the D2D communication link 219 can be operation in a network relay mode. That is, the base station 206 can obtain media content (from either media content server 202 or communication device 215) for communication device 210. The base station 206 detects that communication device 210 is not communicatively coupled to base station 206 and the base station detects that communication device 210 is communicatively coupled to communication device 208 over D2D communication link 219c in response to receiving a notification of the D2D communication link 219c from communication device 208. Further, the base station 206 can send an indication to communication device 208 to provide the media content to communication device 210. In addition, the communication device 208 can obtain the media content from the base station 206 over cellular communication link 216 and the communication device 208 can provide the media content to communication device 210 over D2D communication link 219c through WiFi communication network 220 in response to receiving the indication from base station 206.
Referring to FIG. 2E, in one or more embodiments, system 200d can include communication device 208 communicatively coupled to base station 206 over cellular communication link 216, but communication device 210 is not communicatively coupled to base station 206 over any cellular communication link. Further, communication device 222 associated with user 224 is not communicatively coupled to base station 206. This can be due to communication device 210 and communication device 222 have roamed out of cellular network coverage of base station 206. In addition, the communication device 208 can establish a D2D communication link 219c over WiFi communication network 220 to communication device 210 through a WiFi communication network 220 and communication device 210 can establish a D2D communication link 221 to communication device 222. Thus, in such embodiments the D2D communication link 219c and the D2D communication link 221 can be operating in network relay mode. That is, the base station 206 can obtain media content (from either media content server 202 or communication device 215) for communication device 222. The base station 206 detects that communication device 222 is not communicatively coupled to base station 206 and the base station detects that communication device 222 is communicatively coupled to communication device 208 over D2D communication link 219c and D2D communication link 221 (via communication device 210) in response to receiving a notification of the D2D communication link 219c and D2D communication link 221 from communication device 208. Further, the base station 206 can send an indication to communication device 208 to provide the media content to communication device 222. In addition, the communication device 208 can obtain the media content from the base station 206 over cellular communication link 216 and the communication device 208 can provide the media content to communication device 210 over D2D communication link 219c through WiFi communication network 220 in response to receiving the indication from base station 206.

Further, vehicle communication device 226 and vehicle communication device 228 can each be associated with a first responder vehicle (e.g., police vehicle, firefighter vehicle, emergency medical vehicle, etc.). Vehicle communication device 226 can be communicatively coupled to base station 206 over a cellular communication link 216e and vehicle communication device 226 can be communicatively coupled to base station 206 over a cellular communication link 218e. Further, vehicle communication device 226 can be communicatively coupled to vehicle communication device 228 over a D2D communication link 219e.

In one or more embodiments, vehicle communication device 226 can detect vehicle communication device is in proximity to vehicle communication device 226 within a proximity threshold. Further, the vehicle communication device 226 can establish a D2D communication link 219e with vehicle communication device 228. Once the D2D communication ink 219e has been established, vehicle communication device 226 can notify base station of D2D communication link 219e, accordingly. In addition, the base station 206 can obtain media content from media content server 202 over communication network 204 or from communication device 215 over communication device (or over a cellular communication link). Also, the base station 206 can determine that it cannot provide the media content to vehicle communication device 228 over cellular communication link 218e due to some network condition. Further, the base station 206 provide the media content to vehicle communication device 226 over cellular communication link 216e with an indication to provide the media content to vehicle communication device 228 over D2D communication link 219e. Consequently, the vehicle communication device 226 can provide the media content to vehicle communication device 228 over D2D communication link 219e, once vehicle communication device 226 obtains the media content from base station 206.

In other embodiments, the second communication device is communicatively coupled with the third communication device over a second WiFi network, and the second device-to-device communication link is over the second WiFi network.
In one or more embodiments, the media content comprises one of audio content, video content, or text content. In further embodiments, the media content comprises one of a voice call, a video call, or a text message.
While for purposes of simplicity of explanation, the respective processes are shown and described as a series of blocks in FIG. 2J, it is to be understood and appreciated that the claimed subject matter is not limited by the order of the blocks, as some blocks may occur in different orders and/or concurrently with other blocks from what is depicted and described herein. Moreover, not all illustrated blocks may be required to implement the methods described herein. Further any of blocks can be implemented in response to another block.
Portions of some embodiments can be combined with portions of other embodiments.
Referring now to FIG. 3, a block diagram 300 is shown illustrating an example, non-limiting embodiment of a virtualized communication network in accordance with various aspects described herein. In particular a virtualized communication network is presented that can be used to implement some or all of the subsystems and functions of system 100, the subsystems and functions of system 200, 200a, 200b, 200c, 200d, 200e, 230, 235 and methods 240, 250 presented in FIGS. 1, 2A-2J and 3. For example, virtualized communication network 300 can facilitate in whole or in part a first communication device establishing a device-to-device (D2D) communication link to a second communication device and providing media content over the D2D communication link that was obtained from a base station.
In particular, a cloud networking architecture is shown that leverages cloud technologies and supports rapid innovation and scalability via a transport layer 350, a virtualized network function cloud 325 and/or one or more cloud computing environments 375. In various embodiments, this cloud networking architecture is an open architecture that leverages application programming interfaces (APIs); reduces complexity from services and operations; supports more nimble business models; and rapidly and seamlessly scales to meet evolving customer requirements including traffic growth, diversity of traffic types, and diversity of performance and reliability expectations.
In contrast to traditional network elements—which are typically integrated to perform a single function, the virtualized communication network employs virtual network elements (VNEs) 330, 332, 334, etc. that perform some or all of the functions of network elements 150, 152, 154, 156, etc. For example, the network architecture can provide a substrate of networking capability, often called Network Function Virtualization Infrastructure (NFVI) or simply infrastructure that is capable of being directed with software and Software Defined Networking (SDN) protocols to perform a broad variety of network functions and services. This infrastructure can include several types of substrates. The most typical type of substrate being servers that support Network Function Virtualization (NFV), followed by packet forwarding capabilities based on generic computing resources, with specialized network technologies brought to bear when general purpose processors or general purpose integrated circuit devices offered by merchants (referred to herein as merchant silicon) are not appropriate. In this case, communication services can be implemented as cloud-centric workloads.
As an example, a traditional network element 150 (shown in FIG. 1), such as an edge router can be implemented via a VNE 330 composed of NFV software modules, merchant silicon, and associated controllers. The software can be written so that increasing workload consumes incremental resources from a common resource pool, and moreover so that it's elastic: so the resources are only consumed when needed. In a similar fashion, other network elements such as other routers, switches, edge caches, and middle-boxes are instantiated from the common resource pool. Such sharing of infrastructure across a broad set of uses makes planning and growing infrastructure easier to manage.
In an embodiment, the transport layer 350 includes fiber, cable, wired and/or wireless transport elements, network elements and interfaces to provide broadband access 110, wireless access 120, voice access 130, media access 140 and/or access to content sources 175 for distribution of content to any or all of the access technologies. In particular, in some cases a network element needs to be positioned at a specific place, and this allows for less sharing of common infrastructure. Other times, the network elements have specific physical layer adapters that cannot be abstracted or virtualized, and might require special DSP code and analog front-ends (AFEs) that do not lend themselves to implementation as VNEs 330, 332 or 334. These network elements can be included in transport layer 350.
The virtualized network function cloud 325 interfaces with the transport layer 350 to provide the VNEs 330, 332, 334, etc. to provide specific NFVs. In particular, the virtualized network function cloud 325 leverages cloud operations, applications, and architectures to support networking workloads. The virtualized network elements 330, 332 and 334 can employ network function software that provides either a one-for-one mapping of traditional network element function or alternately some combination of network functions designed for cloud computing. For example, VNEs 330, 332 and 334 can include route reflectors, domain name system (DNS) servers, and dynamic host configuration protocol (DHCP) servers, system architecture evolution (SAE) and/or mobility management entity (MME) gateways, broadband network gateways, IP edge routers for IP-VPN, Ethernet and other services, load balancers, distributers and other network elements. Because these elements don't typically need to forward large amounts of traffic, their workload can be distributed across a number of servers—each of which adds a portion of the capability, and overall which creates an elastic function with higher availability than its former monolithic version. These virtual network elements 330, 332, 334, etc. can be instantiated and managed using an orchestration approach similar to those used in cloud compute services.
The cloud computing environments 375 can interface with the virtualized network function cloud 325 via APIs that expose functional capabilities of the VNEs 330, 332, 334, etc. to provide the flexible and expanded capabilities to the virtualized network function cloud 325. In particular, network workloads may have applications distributed across the virtualized network function cloud 325 and cloud computing environment 375 and in the commercial cloud, or might simply orchestrate workloads supported entirely in NFV infrastructure from these third party locations.
Turning now to FIG. 4, there is illustrated a block diagram of a computing environment in accordance with various aspects described herein. In order to provide additional context for various embodiments of the embodiments described herein, FIG. 4 and the following discussion are intended to provide a brief, general description of a suitable computing environment 400 in which the various embodiments of the subject disclosure can be implemented.

For example, computing environment 400 can facilitate in whole or in part a first communication device establishing a device-to-device (D2D) communication link to a second communication device and providing media content over the D2D communication link that was obtained from a base station. Further, the communication devices, base stations, servers, vehicle communication devices, and network devices (as shown in FIG. 2G) each comprise computing environment 400.
Generally, program modules comprise routines, programs, components, data structures, etc., that perform particular tasks or implement particular abstract data types.

In this regard, the terms "tangible" or "non-transitory" herein as applied to storage, memory or computer-readable media, are to be understood to exclude only propagating transitory signals per se as modifiers and do not relinquish rights to all standard storage, memory or computer-readable media that are not only propagating transitory signals per se.
Computer-readable storage media can be accessed by one or more local or remote computing devices, e.g., via access requests, queries or other data retrieval protocols, for a variety of operations with respect to the information stored by the medium.
Communications media typically embody computer-readable instructions, data structures, program modules or other structured or unstructured data in a data signal such as a modulated data signal, e.g., a carrier wave or other transport mechanism, and comprises any information delivery or transport media. The term "modulated data signal" or signals refers to a signal that has one or more of its characteristics set or changed in such a manner as to encode information in one or more signals. By way of example, and not limitation, communication media comprise wired media, such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media.
With reference again to FIG. 4, the example environment can comprise a computer 402, the computer 402 comprising a processing unit 404, a system memory 406 and a system bus 408. The system bus 408 couples system components including, but not limited to, the system memory 406 to the processing unit 404. The processing unit 404 can be any of various commercially available processors. Dual microprocessors and other multiprocessor architectures can also be employed as the processing unit 404.
The system bus 408 can be any of several types of bus structure that can further interconnect to a memory bus (with or without a memory controller), a peripheral bus, and a local bus using any of a variety of commercially available bus architectures. The system memory 406 comprises ROM 410 and RAM 412. A basic input/output system (BIOS) can be stored in a non-volatile memory such as ROM, erasable programmable read only memory (EPROM), EEPROM, which BIOS contains the basic routines that help to transfer information between elements within the computer 402, such as during startup. The RAM 412 can also comprise a high-speed RAM such as static RAM for caching data.
The computer 402 further comprises an internal hard disk drive (HDD) 414 (e.g., EIDE, SATA), which internal HDD 414 can also be configured for external use in a suitable chassis (not shown), a magnetic floppy disk drive (FDD) 416, (e.g., to read from or write to a removable diskette 418) and an optical disk drive 420, (e.g., reading a CD-ROM disk 422 or, to read from or write to other high capacity optical media such as the DVD). The HDD 414, magnetic FDD 416 and optical disk drive 420 can be connected to the system bus 408 by a hard disk drive interface 424, a magnetic disk drive interface 426 and an optical drive interface 428, respectively. The hard disk drive interface 424 for external drive implementations comprises at least one or both of Universal Serial Bus (USB) and Institute of Electrical and Electronics Engineers (IEEE) 1394 interface technologies. Other external drive connection technologies are within contemplation of the embodiments described herein.
The drives and their associated computer-readable storage media provide nonvolatile storage of data, data structures, computer-executable instructions, and so forth. For the computer 402, the drives and storage media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable storage media above refers to a hard disk drive (HDD), a removable magnetic diskette, and a removable optical media such as a CD or DVD, it should be appreciated by those skilled in the art that other types of storage media which are readable by a computer, such as zip drives, magnetic cassettes, flash memory cards, cartridges, and the like, can also be used in the example operating environment, and further, that any such storage media can contain computer-executable instructions for performing the methods described herein.
A number of program modules can be stored in the drives and RAM 412, comprising an operating system 430, one or more application programs 432, other program modules 434 and program data 436. All or portions of the operating system, applications, modules, and/or data can also be cached in the RAM 412. The systems and methods described herein can be implemented utilizing various commercially available operating systems or combinations of operating systems.
A user can enter commands and information into the computer 402 through one or more wired/wireless input devices, e.g., a keyboard 438 and a pointing device, such as a mouse 440. Other input devices (not shown) can comprise a microphone, an infrared (IR) remote control, a joystick, a game pad, a stylus pen, touch screen or the like. These and other input devices are often connected to the processing unit 404 through an input device interface 442 that can be coupled to the system bus 408, but can be connected by other interfaces, such as a parallel port, an IEEE 1394 serial port, a game port, a universal serial bus (USB) port, an IR interface, etc.
A monitor 444 or other type of display device can be also connected to the system bus 408 via an interface, such as a video adapter 446. It will also be appreciated that in alternative embodiments, a monitor 444 can also be any display device (e.g., another computer having a display, a smart phone, a tablet computer, etc.) for receiving display information associated with computer 402 via any communication means, including via the Internet and cloud-based networks. In addition to the monitor 444, a computer typically comprises other peripheral output devices (not shown), such as speakers, printers, etc.
The computer 402 can operate in a networked environment using logical connections via wired and/or wireless communications to one or more remote computers, such as a remote computer(s) 448. The remote computer(s) 448 can be a workstation, a server computer, a router, a personal computer, portable computer, microprocessor-based entertainment appliance, a peer device or other common network node, and typically comprises many or all of the elements described relative to the computer 402, although, for purposes of brevity, only a remote memory/storage device 450 is illustrated. The logical connections depicted comprise wired/wireless connectivity to a local area network (LAN) 452 and/or larger networks, e.g., a wide area network (WAN) 454. Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which can connect to a global communications network, e.g., the Internet.
When used in a LAN networking environment, the computer 402 can be connected to the LAN 452 through a wired and/or wireless communication network interface or adapter 456. The adapter 456 can facilitate wired or wireless communication to the LAN 452, which can also comprise a wireless AP disposed thereon for communicating with the adapter 456.
When used in a WAN networking environment, the computer 402 can comprise a modem 458 or can be connected to a communications server on the WAN 454 or has other means for establishing communications over the WAN 454, such as by way of the Internet. The modem 458, which can be internal or external and a wired or wireless device, can be connected to the system bus 408 via the input device interface 442. In a networked environment, program modules depicted relative to the computer 402 or portions thereof, can be stored in the remote memory/storage device 450. It will be appreciated that the network connections shown are example and other means of establishing a communications link between the computers can be used.
The computer 402 can be operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag (e.g., a kiosk, news stand, restroom), and telephone. This can comprise Wireless Fidelity (Wi-Fi) and BLUETOOTH® wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.
Wi-Fi can allow connection to the Internet from a couch at home, a bed in a hotel room or a conference room at work, without wires. Wi-Fi is a wireless technology similar to that used in a cell phone that enables such devices, e.g., computers, to send and receive data indoors and out; anywhere within the range of a base station. Wi-Fi networks use radio technologies called IEEE 802.11 (a, b, g, n, ac, ag, etc.) to provide secure, reliable, fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet, and to wired networks (which can use IEEE 802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands for example or with products that contain both bands (dual band), so the networks can provide real-world performance similar to the basic 10BaseT wired Ethernet networks used in many offices.
Turning now to FIG. 5, an embodiment 500 of a mobile network platform 510 is shown that is an example of network elements 150, 152, 154, 156, and/or VNEs 330, 332, 334, etc. For example, platform 510 can facilitate in whole or in part a first communication device establishing a device-to-device (D2D) communication link to a second communication device and providing media content over the D2D communication link that was obtained from a base station. In one or more embodiments, the mobile network platform 510 can generate and receive signals transmitted and received by base stations or access points such as base station or access point 122. Generally, mobile network platform 510 can comprise components, e.g., nodes, gateways, interfaces, servers, or disparate platforms, that facilitate both packet-switched (PS) (e.g., internet protocol (IP), frame relay, asynchronous transfer mode (ATM)) and circuit-switched (CS) traffic (e.g., voice and data), as well as control generation for networked wireless telecommunication. As a non-limiting example, mobile network platform 510 can be included in telecommunications carrier networks, and can be considered carrier-side components as discussed elsewhere herein. Mobile network platform 510 comprises CS gateway node(s) 512 which can interface CS traffic received from legacy networks like telephony network(s) 540 (e.g., public switched telephone network (PSTN), or public land mobile network (PLMN)) or a signaling system #7 (SS7) network 560. CS gateway node(s) 512 can authorize and authenticate traffic (e.g., voice) arising from such networks. Additionally, CS gateway node(s) 512 can access mobility, or roaming, data generated through SS7 network 560; for instance, mobility data stored in a visited location register (VLR), which can reside in memory 530. Moreover, CS gateway node(s) 512 interfaces CS-based traffic and signaling and PS gateway node(s) 518. As an example, in a 3GPP UMTS network, CS gateway node(s) 512 can be realized at least in part in gateway GPRS support node(s) (GGSN). It should be appreciated that functionality and specific operation of CS gateway node(s) 512, PS gateway node(s) 518, and serving node(s) 516, is provided and dictated by radio technology(ies) utilized by mobile network platform 510 for telecommunication over a radio access network 520 with other devices, such as a radiotelephone 575.
In addition to receiving and processing CS-switched traffic and signaling, PS gateway node(s) 518 can authorize and authenticate PS-based data sessions with served mobile devices. Data sessions can comprise traffic, or content(s), exchanged with networks external to the mobile network platform 510, like wide area network(s) (WANs) 550, enterprise network(s) 570, and service network(s) 580, which can be embodied in local area network(s) (LANs), can also be interfaced with mobile network platform 510 through PS gateway node(s) 518. It is to be noted that WANs 550 and enterprise network(s) 570 can embody, at least in part, a service network(s) like IP multimedia subsystem (IMS). Based on radio technology layer(s) available in technology resource(s) or radio access network 520, PS gateway node(s) 518 can generate packet data protocol contexts when a data session is established; other data structures that facilitate routing of packetized data also can be generated. To that end, in an aspect, PS gateway node(s) 518 can comprise a tunnel interface (e.g., tunnel termination gateway (TTG) in 3GPP UMTS network(s) (not shown)) which can facilitate packetized communication with disparate wireless network(s), such as Wi-Fi networks.
In embodiment 500, mobile network platform 510 also comprises serving node(s) 516 that, based upon available radio technology layer(s) within technology resource(s) in the radio access network 520, convey the various packetized flows of data streams received through PS gateway node(s) 518. It is to be noted that for technology resource(s) that rely primarily on CS communication, server node(s) can deliver traffic without reliance on PS gateway node(s) 518; for example, server node(s) can embody at least in part a mobile switching center. As an example, in a 3GPP UMTS network, serving node(s) 516 can be embodied in serving GPRS support node(s) (SGSN).
For radio technologies that exploit packetized communication, server(s) 514 in mobile network platform 510 can execute numerous applications that can generate multiple disparate packetized data streams or flows, and manage (e.g., schedule, queue, format . . . ) such flows. Such application(s) can comprise add-on features to standard services (for example, provisioning, billing, customer support . . . ) provided by mobile network platform 510. Data streams (e.g., content(s) that are part of a voice call or data session) can be conveyed to PS gateway node(s) 518 for authorization/authentication and initiation of a data session, and to serving node(s) 516 for communication thereafter. In addition to application server, server(s) 514 can comprise utility server(s), a utility server can comprise a provisioning server, an operations and maintenance server, a security server that can implement at least in part a certificate authority and firewalls as well as other security mechanisms, and the like. In an aspect, security server(s) secure communication served through mobile network platform 510 to ensure network's operation and data integrity in addition to authorization and authentication procedures that CS gateway node(s) 512 and PS gateway node(s) 518 can enact. Moreover, provisioning server(s) can provision services from external network(s) like networks operated by a disparate service provider; for instance, WAN 550 or Global Positioning System (GPS) network(s) (not shown). Provisioning server(s) can also provision coverage through networks associated to mobile network platform 510 (e.g., deployed and operated by the same service provider), such as the distributed antennas networks shown in FIG. 1(s) that enhance wireless service coverage by providing more network coverage.
It is to be noted that server(s) 514 can comprise one or more processors configured to confer at least in part the functionality of mobile network platform 510. To that end, the one or more processor can execute code instructions stored in memory 530, for example. It is should be appreciated that server(s) 514 can comprise a content manager, which operates in substantially the same manner as described hereinbefore.
In example embodiment 500, memory 530 can store information related to operation of mobile network platform 510. Other operational information can comprise provisioning information of mobile devices served through mobile network platform 510, subscriber databases; application intelligence, pricing schemes, e.g., promotional rates, flat-rate programs, couponing campaigns; technical specification(s) consistent with telecommunication protocols for operation of disparate radio, or wireless, technology layers; and so forth. Memory 530 can also store information from at least one of telephony network(s) 540, WAN 550, SS7 network 560, or enterprise network(s) 570. In an aspect, memory 530 can be, for example, accessed as part of a data store component or as a remotely connected memory store.
In order to provide a context for the various aspects of the disclosed subject matter, FIG. 5, and the following discussion, are intended to provide a brief, general description of a suitable environment in which the various aspects of the disclosed subject matter can be implemented. While the subject matter has been described above in the general context of computer-executable instructions of a computer program that runs on a computer and/or computers, those skilled in the art will recognize that the disclosed subject matter also can be implemented in combination with other program modules. Generally, program modules comprise routines, programs, components, data structures, etc. that perform particular tasks and/or implement particular abstract data types.
Turning now to FIG. 6, an illustrative embodiment of a communication device 600 is shown. The communication device 600 can serve as an illustrative embodiment of devices such as data terminals 114, mobile devices 124, vehicle 126, display devices 144 or other client devices for communication via either communications network 125.

The keypad 608 can represent a numeric keypad commonly used by phones, and/or a QWERTY keypad with alphanumeric keys. The UI 604 can further include a display 610 such as monochrome or color LCD (Liquid Crystal Display), OLED (Organic Light Emitting Diode) or other suitable display technology for conveying images to an end user of the communication device 600. In an embodiment where the display 610 is touch-sensitive, a portion or all of the keypad 608 can be presented by way of the display 610 with navigation features.
The display 610 can use touch screen technology to also serve as a user interface for detecting user input. As a touch screen display, the communication device 600 can be adapted to present a user interface having graphical user interface (GUI) elements that can be selected by a user with a touch of a finger. The display 610 can be equipped with capacitive, resistive or other forms of sensing technology to detect how much surface area of a user's finger has been placed on a portion of the touch screen display. This sensing information can be used to control the manipulation of the GUI elements or other functions of the user interface. The display 610 can be an integral part of the housing assembly of the communication device 600 or an independent device communicatively coupled thereto by a tethered wireline interface (such as a cable) or a wireless interface.
The UI 604 can also include an audio system 612 that utilizes audio technology for conveying low volume audio (such as audio heard in proximity of a human ear) and high volume audio (such as speakerphone for hands free operation). The audio system 612 can further include a microphone for receiving audible signals of an end user. The audio system 612 can also be used for voice recognition applications. The UI 604 can further include an image sensor 613 such as a charged coupled device (CCD) camera for capturing still or moving images.
The power supply 614 can utilize common power management technologies such as replaceable and rechargeable batteries, supply regulation technologies, and/or charging system technologies for supplying energy to the components of the communication device 600 to facilitate long-range or short-range portable communications. Alternatively, or in combination, the charging system can utilize external power sources such as DC power supplied over a physical interface such as a USB port or other suitable tethering technologies.
The location receiver 616 can utilize location technology such as a global positioning system (GPS) receiver capable of assisted GPS for identifying a location of the communication device 600 based on signals generated by a constellation of GPS satellites, which can be used for facilitating location services such as navigation. The motion sensor 618 can utilize motion sensing technology such as an accelerometer, a gyroscope, or other suitable motion sensing technology to detect motion of the communication device 600 in three-dimensional space. The orientation sensor 620 can utilize orientation sensing technology such as a magnetometer to detect the orientation of the communication device 600 (north, south, west, and east, as well as combined orientations in degrees, minutes, or other suitable orientation metrics).
The communication device 600 can use the transceiver 602 to also determine a proximity to a cellular, WiFi, Bluetooth®, or other wireless access points by sensing techniques such as utilizing a received signal strength indicator (RSSI) and/or signal time of arrival (TOA) or time of flight (TOF) measurements. The controller 606 can utilize computing technologies such as a microprocessor, a digital signal processor (DSP), programmable gate arrays, application specific integrated circuits, and/or a video processor with associated storage memory such as Flash, ROM, RAM, SRAM, DRAM or other storage technologies for executing computer instructions, controlling, and processing data supplied by the aforementioned components of the communication device 600.
Other components not shown in FIG. 6 can be used in one or more embodiments of the subject disclosure. For instance, the communication device 600 can include a slot for adding or removing an identity module such as a Subscriber Identity Module (SIM) card or Universal Integrated Circuit Card (UICC). SIM or UICC cards can be used for identifying subscriber services, executing programs, storing subscriber data, and so on.
The terms "first," "second," "third," and so forth, as used in the claims, unless otherwise clear by context, is for clarity only and doesn't otherwise indicate or imply any order in time. For instance, "a first determination," "a second determination," and "a third determination," does not indicate or imply that the first determination is to be made before the second determination, or vice versa, etc.
In the subject specification, terms such as "store," "storage," "data store," data storage," "database," and substantially any other information storage component relevant to operation and functionality of a component, refer to "memory components," or entities embodied in a "memory" or components comprising the memory. It will be appreciated that the memory components described herein can be either volatile memory or nonvolatile memory, or can comprise both volatile and nonvolatile memory, by way of illustration, and not limitation, volatile memory, non-volatile memory, disk storage, and memory storage. Further, nonvolatile memory can be included in read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable ROM (EEPROM), or flash memory. Volatile memory can comprise random access memory (RAM), which acts as external cache memory. By way of illustration and not limitation, RAM is available in many forms such as synchronous RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), and direct Rambus RAM (DRRAM). Additionally, the disclosed memory components of systems or methods herein are intended to comprise, without being limited to comprising, these and any other suitable types of memory.
Moreover, it will be noted that the disclosed subject matter can be practiced with other computer system configurations, comprising single-processor or multiprocessor computer systems, mini-computing devices, mainframe computers, as well as personal computers, hand-held computing devices (e.g., PDA, phone, smartphone, watch, tablet computers, netbook computers, etc.), microprocessor-based or programmable consumer or industrial electronics, and the like. The illustrated aspects can also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network; however, some if not all aspects of the subject disclosure can be practiced on stand-alone computers. In a distributed computing environment, program modules can be located in both local and remote memory storage devices.
In one or more embodiments, information regarding use of services can be generated including services being accessed, media consumption history, user preferences, and so forth. This information can be obtained by various methods including user input, detecting types of communications (e.g., video content vs. audio content), analysis of content streams, sampling, and so forth. The generating, obtaining and/or monitoring of this information can be responsive to an authorization provided by the user. In one or more embodiments, an analysis of data can be subject to authorization from user(s) associated with the data, such as an opt-in, an opt-out, acknowledgement requirements, notifications, selective authorization based on types of data, and so forth.
Some of the embodiments described herein can also employ artificial intelligence (AI) to facilitate automating one or more features described herein. The embodiments (e.g., in connection with automatically identifying acquired cell sites that provide a maximum value/benefit after addition to an existing communication network) can employ various AI-based schemes for carrying out various embodiments thereof. Moreover, the classifier can be employed to determine a ranking or priority of each cell site of the acquired network. A classifier is a function that maps an input attribute vector, x=(x1, x2, x3, x4, . . . , xn), to a confidence that the input belongs to a class, that is, f(x)=confidence (class). Such classification can employ a probabilistic and/or statistical-based analysis (e.g., factoring into the analysis utilities and costs) to determine or infer an action that a user desires to be automatically performed. A support vector machine (SVM) is an example of a classifier that can be employed. The SVM operates by finding a hypersurface in the space of possible inputs, which the hypersurface attempts to split the triggering criteria from the non-triggering events. Intuitively, this makes the classification correct for testing data that is near, but not identical to training data. Other directed and undirected model classification approaches comprise, e.g., naïve Bayes, Bayesian networks, decision trees, neural networks, fuzzy logic models, and probabilistic classification models providing different patterns of independence can be employed. Classification as used herein also is inclusive of statistical regression that is utilized to develop models of priority.
As will be readily appreciated, one or more of the embodiments can employ classifiers that are explicitly trained (e.g., via a generic training data) as well as implicitly trained (e.g., via observing UE behavior, operator preferences, historical information, receiving extrinsic information). For example, SVMs can be configured via a learning or training phase within a classifier constructor and feature selection module. Thus, the classifier(s) can be used to automatically learn and perform a number of functions, including but not limited to determining according to predetermined criteria which of the acquired cell sites will benefit a maximum number of subscribers and/or which of the acquired cell sites will add minimum value to the existing communication network coverage, etc.

Liberty's Coach Freeze agrees to deal with Auburn
By Eddie Callahan
Published: Nov. 28, 2022 at 3:06 PM CST
LYNCHBURG, Va. (WDBJ) - According to multiple sources, including ESPN and Fox Sports, Liberty football coach Hugh Freeze has agreed to a deal to become the new Auburn leader.
He will finish at Liberty with a 34-15 tally and will replace Bryan Harsin, who was fired on Oct. 31 after going 9-12 in less than two seasons.
Freeze officially began as leader of the Liberty University football program in December of 2018 as the ninth head coach in program history. He had held the same position at Lambuth University (2008-09), Arkansas State (2011) and Ole Miss (2012-16) prior to arriving in the Hill City.
Under Freeze, the Flames became the second team in NCAA history to secure a bowl game victory during its first three full seasons at the FBS level (2019, 2020 and 2021).
"We are grateful to Coach Freeze for all he has done for Liberty Football and the University over the past four seasons. We wish Hugh, Jill, and their daughters God's richest blessings as they embark on a new journey," said the school's director of athletics, Ian McCaw.
President Jerry Prevo added, "There could be no better compliment to our university than that the best place Auburn could come to find its next coach was Liberty University."
The school says it has already started looking for a replacement with a national search.
BREAKING: Liberty coach Hugh Freeze is coming back to the SEC, per source. Auburn is hiring him as its new head coach. @RossDellenger first reported the move.
