Apparatus and method for providing quality of service in wireless communication system

摘要

Provided are an apparatus and a method for providing a quality of service (QoS) in a wireless communication system. The method includes transmitting an enable media message that includes QoS information of the application layers from an Internet Protocol (IP) Multimedia Subsystem (IMS) server to a policy server, transforming and mapping the QoS information of the application layer into QoS information of an IP layer in the policy server and transmitting a common open policy service decision (COPS-DEC) message that includes the QoS information of the IP layer from the policy server to a base station (BS), and transforming and mapping the QoS information of the IP layer into QoS information of a media access control (MAC) layer in the BS and transmitting a dynamic service addition request (DSA-REQ) message that includes the QoS information of the MAC layer from the BS to the transmitter terminal.
