AN END-TO-END QoS MANAGEMENT FRAMEWORK FOR STREAMING SERVICES IN 3G MOBILE NETWORKS

摘要

In this paper, an end-to-end Quality of Service (QoS) framework for streaming services in 3G mobile networks is considered. A solution based on a Public Land Mobile Network (PLMN) hosted multimedia streaming service is studied to avoid accessing through an external IP packet data network (IP-PDN) to streaming services. Under this scenario, the interaction between UMTS and IETF's protocols and mechanisms for a streaming session is analyzed. By signaling flowcharts, it is shown that both groups of protocols and mechanisms can cooperate to provide seamless end-to-end real-time services. Supported by this proposed framework, provisioning of audio streaming services over 3G mobile networks is also addressed.
