摘　　要：论述了纯分组接入的3GPP LTE优化系统,此优化系统可以提供更高的数据速率、更低的传输时延,提高其覆盖范围和频谱利用率。介绍了3GPP提出的有关符合LTE标准一些主要特征,包括优化信令、优化无线传输和无线接入网。主要讨论了符合LTE标准的ESM协议所应考虑的一些内容,如网络控制的业务、QoS聚合和缺省IP接入业务。最后,分析了ESM信令协议的会话建立时延,结果表明,LTE系统中ESM信令协议较先前的3G UMTS系统有很大的改善。In this paper,the pure packet access 3GPP LTE optimization system is discussed,This optimization system can provide higher data rates,lower transmission delay,and improve their coverage and spectral efficiency.3GPP questions about some of the key features of LTE standard are introduced,it includes the optimization of signaling,optimizing the wireless transmission and wireless access networks.The paper mainly discussed in line with LTE standard and some of the content which should be taken into account by ESM protocol,such as network control operations,QoS aggregation,and the default IP access service.At last,the session setup delay of the ESM signaling protocol is analysed,it shows that the ESM signaling protocols of the LTE system over previous 3G UMTS system has a significant improvement.
