LTE系统是3GPP推出的第三代移动通信系统的演进版本。S1AP协议作为其接入网和核心网接口S1-MME的一个应用层协议,控制着接入网和核心网之间信令和数据的传输。为研究S1AP协议,就S1AP协议的功能和相关的基本过程进行了描述和总结,并重点阐述了E-RAB建立过程、初始上下文建立过程、寻呼过程和NAS传输过程等典型的S1AP基本过程。这对进一步研究S1AP协议有一定的帮助。

LTE system is the evolution version of 3GPP the third generation mobile communication system.S1AP protocol,an application layer protocol of interface S1-MME between the access network and the core network,controls the signaling and data transmission between the access network and the core network.The functions and elementary procedures of S1AP protocol are described and summarized,and the E-RAB setup procedure,initial context setup procedure,paging procedure and NAS transport procedure are focused on,which is helpful to further research of S1AP protocol.
