Methods systems and computer readable media for providing real time data network usage information using subscription profile repository (SPR)

A system for providing real time data network usage information for a subscriber utilizing a subscription profile repository (SPR), the system comprising:

• an SPR comprising:
• a processor;
• a first interface for receiving, from a policy and charging rules function (PCRF), a message subscribing to data change notifications for a subscriber;
• a second interface for receiving, from a network device separate from the PCRF, a data change request for the subscriber;
• wherein the first interface transmits from the SPR to the PCRF as a consequence of the PCRF subscribing to the data change notifications for the subscriber and the data change request, a push notification request (PNR) for real time data network usage information for the subscriber;
• and
• wherein the second interface receives, from the PCRF, an indication of the real time data network usage information.

A non-transitory computer readable medium having stored thereon executable instructions that when executed by the processor of a computer control the computer to perform steps comprising:

• at the SPR:
• receiving, from a policy and charging rules function (PCRF), a message subscribing to data change notifications for a subscriber;
• receiving, from a network device separate from the PCRF, a data change request for the subscriber;
• transmitting from the SPR to the PCRF as a consequence of the PCRF subscribing to the data change notifications for the subscriber and the data change request, a push notification request (PNR) for real time data network usage information for the subscriber;
• and
• receiving, from the PCRF, an indication of the real time data network usage for the subscriber.
