摘要: 下一代移动通信中实时多媒体业务对网络的服务性能提出了更高的要求,如低切换时延和低丢包率。针对上述要求,提出一种层次化的基于双播机制的SIP协议(HBSIP)。HBSIP是对现有移动SIP协议的改进,其关键是双播机制和分层结构。分析表明,HBSIP能大幅度降低移动主机切换时延和丢包率。

Abstract: In the next generation network, real-time multimedia applications need better network performance, such as lower handoff delay and packet loss rate. This paper proposes a new protocol named Hierarchical Bicasing-based SIP(HBSIP). HBSIP is an improved version of traditional mobile SIP, its key idea is the use of bicasting mechanism and hierarchical structure. HBSIP may increase additional network traffic load, and significantly enhances the network performance, such as reducing handoff delay and packet loss rate.

Key words: mobile SIP, bicasting mechanism, hierarchical structure, seamless handover
