Patent ID: 11956302

Abstract:
The present disclosure describes a device, computer-readable medium, and method for an IPv4-to-IPv6 redirect to enable use of application function-specific user endpoint identifiers (AF-specific UEIds). In one example, a method performed by a processing system includes receiving, from an application function of a communications network, a redirected request for an AF-specific UEId that is unique to a user endpoint device and the application function, where the redirected request includes an IPv6 address associated with the user endpoint device, querying a binding support function of the communications network for a subscription permanent identifier associated with the IPv6 address associated with the user endpoint device, querying an application function-specific management function for an AF-specific UEId associated with the subscription permanent identifier and an identifier of the application function, and forwarding the AF-specific UEId associated with the subscription permanent identifier and the identifier of the application function to the application function.
