Providing data file updates using multimedia broadcast multicast services

A network node comprising:

• a memory comprising instructions;
• and
• a processor coupled to the memory and configured to execute the instructions such that the network node:
• receives a first Session Initiation Protocol (SIP) message comprising at least one application identifier (App-ID) and at least one user ID associated with the at least one App-ID, wherein the at least one App-ID identifies at least one application in which at least a first user equipment (UE) and a second UE are both interested, wherein the at least one user ID identifies at least one of the first UE or the second UE, and wherein the network node receives the first SIP message from the first UE or the second UE;
• sends a second SIP message requesting to receive notifications of updates to application data associated with the at least one App-ID;
• configures a broadcast entity to transmit updated application data associated with the at least one App-ID;
• and
• sends configuration data to the first and second UEs for receiving the updated application data from the broadcast entity.

A non-transitory computer-readable medium comprising instructions executable by a processor such that when executed, cause the processor to implement a method on a network node, the method comprising:

• receiving, at the network node, a first Session Initiation Protocol (SIP) message comprising at least one application identifier (App-ID) and at least one user ID associated with the at least one App-ID, wherein the at least one App-ID identifies at least one application in which at least a first user equipment (UE) and a second UE are both interested, wherein the at least one user ID identifies at least one of the first UE or the second UE, and wherein the network node receives the first SIP message from the first UE or the second UE;
• sending, by the network node, a second SIP message requesting to receive notifications of updates to application data associated with the at least one App-ID;
• configuring, by the network node, a broadcast entity to transmit updated application data associated with the at least one App-ID;
• and
• sending, by the network node, configuration data to the first and second UEs for receiving the updated application data from the broadcast entity.
