Single IMSI implementation The online interfaces that are defined further in this document enable a real-time charging and management of the customer (mobility) at the ARP. Architecture Inside the Single IMSI architecture, the following parameters shall be unique and controlled by the DSP HLR to VLR SS profile, SMSC address, APN for data services, PCRF parameters Conditions for triggering the Proxies for enabling separation of sale The following table summarizes the conditions to be fulfilled for triggering the corresponding interface. IF Event Subscriber Location Destination Type IF1 MOC Calling subscriber In ARP coverage In ARP destination set In ARP call type belongs to ARP IF1 MFC Redirecting subscriber In ARP coverage In ARP destination set In ARP call type belongs to ARP IF1 MTC Called subscriber In ARP coverage n.a.

USSD belongs to ARP on the USSD designated for ARP service only in – ARP coverage (*) IF5 DSP Dialing subscriber Any or depending Using USSD designated n.a. USSD belongs to ARP on the USSD for DSP service only in – DSP coverage (*) (*): in case of USSD interface is used for triggering USSD Call back service (offered by DSP or ARP), the DSP may apply a location control validating whether the roamer is in the ARP/DSP coverage. The invocation at DSP and the control at the ARP requires at least: Subscriber identification Location information Event type and destination The definition and relevant parameters are defined in the following sections.
