Methods and Apparatuses for Implementing a Service Request

A method in an application client connected to a core network via a wireless device, wherein the application client is unaware of a session binding internet protocol (IP) address associated with a Protocol Data Unit (PDU) session established between the wireless device and an anchor point to a data network, the method comprising:

• transmitting an address request to an address resolver function, wherein the address resolver function is connected between the wireless device and a Network Address Translation (NAT) function;
• receiving an indication of the session binding IP address from the address resolver function;
• and
• transmitting an augmented service request to an application function, wherein the augmented service request comprises the session binding IP address.

An application client connected to a core network via a wireless device, wherein the application client is unaware of a session binding internet protocol (IP) address associated with a Protocol Data Unit (PDU) session established between the wireless device and an anchor point to a data network, the application client comprising:

• processing circuitry and a memory, the memory containing instructions executable by the processing circuitry such that the processing circuity is configured to:
• transmit an address request to an address resolver function, wherein the address resolver function is connected between the wireless device and a Network Address Translation, NAT, function;
• receive an indication of the session binding IP address from the address resolver function;
• and
• transmit an augmented service request to an application function, wherein the augmented service request comprises the session binding IP address.

An application function for implementing an augmented service request from an application client connected to a core network via a wireless device, the application function comprising:

• processing circuitry and a memory, the memory containing instructions executable by the processing circuitry such that the processing circuity is configured to:
• receive the augmented service request from the application client, wherein the augmented service request comprises a session binding internet protocol, IP, address associated with a Protocol Data Unit (PDU) session established between the wireless device and an anchor point to a data network;
• and
• forward, to a network function, the augmented service request.
