Application-specific GPSI retrieval

A method for an application function (AF) associated with a communication network, the method comprising:

• receiving, from a user equipment (UE), an application service request including:
• a second identifier (GPSI) of the UE that is specific to one or more applications, including an application associated with the UE and the AF;
• and
• information (app-info) associated with the second identifier and descriptive of the one or more applications;
• sending, to a network function (NF) of the communication network, a request for a corresponding second identifier (GPSI*) of the UE that is specific to the application associated with the UE and with the AF, wherein the request includes the received information descriptive of the one or more applications;
• and
• receiving the corresponding second identifier from the NF.

A method for a network function (NF) of a communication network, the method comprising:

• receiving, from an application function (AF) associated with the communication network, a request for a corresponding second identifier (GPSI*) of a user equipment (UE) that is specific to an application associated with the UE and with the AF, wherein the request includes information (app-info) descriptive of one or more applications, including the application associated with the UE and with the AF, and
• obtaining the corresponding second identifier (GPSI*) based on the information descriptive of the one or more applications;
• and
• sending the corresponding second identifier (GPSI*) to the AF.

A network function (NF) of a communication network, comprising:

• processing circuitry, memory and transceiver circuitry collectively configured to perform operations comprising:
• receiving, from an application function (AF) associated with the communication network, a request for a corresponding second identifier (GPSI*) of a user equipment (UE) that is specific to an application associated with the UE and with the AF, wherein the request includes information (app-info) descriptive of one or more applications, including the application associated with the UE and with the AF, and
• obtaining the corresponding second identifier (GPSI*) based on the information descriptive of the one or more applications;
• and
• sending the corresponding second identifier (GPSI*) to the AF.
