Application of IP Multimedia Streaming Services in Third-generation Mobile Networks

An end-to-end QoS framework for streaming services in 3G mobile networks is studied and the possibility of applying IP multimedia streaming services in PLMN is discussed.Under this scenario,the interaction between UMTS and IETF's protocols and mechanisms for a streaming session are analyzed.It is shown that both groups of protocols and mechanisms can co-operate to provide seamless end-to-end real-time services.Specifically,the article proposes to make the IP multimedia subsystem aware of real time streaming protocol,in order to extend its control from SIP to RTSP-based services,such as multimedia streaming services.Supported by this proposed framework,provision of audio streaming services on 3G mobile networks is also outlined.
