✦ Synopsis

This letter addresses how quality of service (QoS) for Session Initiation Protocol (SIP)-based multimedia sessions can be realized within the 3rd Generation Partnership Project (3GPP) architecture. It discusses a scenario for voice over IP (VoIP) to illustrate how relevant QoS mechanisms and signaling protocols such as SIP, Media Gateway Control Protocol (H.248/Megaco), and the Common Open Policy Service (COPS) interact. Related aspects of the Universal Mobile Telecommunications System (UMTS) access network and the IP Multimedia Subsystem (IMS) are explained.
