to devices 102 with the correct credentials network gateway 108 may be integrated into the hardware of network 104 or may be a separate system connected to network 104 credentials may include one or more than one element and may consist of for example a telephone number network address or link local address the range of allowed credentials may change over time and the determination of whether credentials are valid may be static or dynamic for example static credentials may be fixed or dynamic credentials may be determined based upon a pre determined formula as discussed below credentials may be permanent or may be temporary network 104 may allow a device or devices 102 with credentials in a subset of a valid range access only to a subset of the network for example to management server 106 credentials may also be used to determine other aspects of a device 39 s access to network 104 or systems connected to network 104 such as indicating subscription level examples of using credentials to indicate subscription level would include programming network gateway 108 or other systems connected to network 104 to allow credentials within different subsets of the valid range to access different areas of the network or to be given a faster connection speed or have access to specific systems connected to network 104 network gateway 108 may direct communications that are initiated by devices 102 that have temporary credentials for example within a certain range to a destination connected to gateway 104 for example to management server 106 regardless of the destination specified by.
