Claim 0:
1. A method comprising:
receiving, from an application function of a communications network by a processing system including at least one processor, 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, by the processing system, 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, by the processing system, 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, by the processing system, the application function-specific user endpoint identifier associated with the subscription permanent identifier and the identifier of the application function to the application function.
