Claim 19:
20. A system comprising:
a processing system including at least one processor; and
a non-transitory computer-readable medium storing instructions which, when executed by the processing system, cause the processing system to perform operations, the operations comprising:
receiving, from an application function of a communications network, a redirected request for an application function-specific user endpoint identifier that is unique to a combination of a user endpoint device and the application function, where a version of the redirected request that was sent from the user endpoint device to the application function included an internet protocol version 4 address associated with the user endpoint device that the application function could not map to the application function-specific user endpoint identifier and the redirected request includes an identifier of the application function and an internet protocol version 6 address associated with the user endpoint device;
querying a binding support function of the communications network for a subscription permanent identifier associated with the internet protocol version 6 address associated with the user endpoint device;
querying an application function-specific management function for an application function-specific user endpoint identifier associated with the subscription permanent identifier and the identifier of the application function; and
forwarding the application function-specific user endpoint identifier associated with the subscription permanent identifier and the identifier of the application function to the application function.
