Method and apparatus for provisioning real-time communication service in wireless communication system

A method performed by a real-time communication application function (AF) for supporting a real-time communication between a first user equipment (UE) and a second UE in a wireless communication system, the method comprising:

• receiving, from a real-time communication web server function (WSF) providing the real-time communication, a first request of a quality of service (QoS) configuration for a session of the real-time communication;
• and
• transmitting, to a policy control function (PCF), the first request of the QoS configuration for the session of the real-time communication,
• wherein the session of the real-time communication is established between the first UE, the second UE and the real-time communication WSF, and
• wherein the session of the real-time communication is related to a description offer transmitted from the first UE.

A method performed by a real-time communication web server function (WSF) for supporting a real-time communication between a first user equipment (UE) and a second UE in a wireless communication system, the method comprising:

• receiving, from a real-time communication aware application of the first UE, a first request with a description offer related to a session of the real-time communication;
• transmitting, to the second UE, the first request with the description offer related to the session of the real-time communication;
• establishing the session of the real-time communication with the first UE and the second UE;
• and
• transmitting, to a policy control function (PCF) through a real-time communication application function (AF), a second request of a quality of service (QoS) configuration for the session of the real-time communication.

A real-time communication application function (AF) entity for supporting a real-time communication between a first user equipment (UE) and a second UE in a wireless communication system, the real-time communication AF entity comprising:

• a transceiver;
• and
• at least one processor coupled to the transceiver and configured to:
• receive, from a real-time communication web server function (WSF) providing the real-time communication, a first request of a quality of service (QoS) configuration for a session of the real-time communication, and
• transmit, to a policy control function (PCF), the first request of the QoS configuration for the session of the real-time communication,
• wherein the session of the real-time communication is established between the first UE, the second UE and the real-time communication WSF, and
• wherein the session of the real-time communication is related to a description offer transmitted from the first UE.
