摘要
随着电力IMS系统的全面推广应用,SIP用户与通信业务的增多使得有限带宽与冗余消息之间的矛盾日益凸显,对通信质量与用户体验造成一定影响。论文在深入研究SIP会话端到端建立过程的基础上,构建了SIP时延分析模型,进而指出压缩SIP消息的大小可有效改善SIP的会话性能。通过基于文本的无损数据压缩算法的研究,提出了一种基于SIP协议的改进压缩算法,从而为电力IMS系统服务质量(QoS)的提升给出了一个新思路。
With the comprehensive promotion and application of power IMS system,the contradiction between limited band⁃width and redundant messages has become increasingly prominent with the increase of SIP users and communication services,which has a certain impact on communication quality and user experience.Based on the in-depth study of SIP session end-to-end establishment process,this paper constructs a SIP delay analysis model,and then points out that compressing the size of SIP mes⁃sages can effectively improve SIP session performance.Through the research of text-based lossless data compression algorithm,an improved compression algorithm based on SIP protocol is proposed,which provides a new idea for improving the quality of service(QoS)of power IMS system.
