Network attachment method and system

一种网络附着方法及系统

Abstract

The invention discloses a network attachment method and a system. The method includes: a CN controller receives an attachment request sent by a terminal and transmitted in a transparent manner via a radio access network RAN controller; the CN controller performs authentication of the terminal and accomplishes quality of service QoS processing, and an S1 bearer and a radio bearer are established for the terminal; and the CN controller sends addresses of network element nodes for data transmission and tunnel endpoint identifier TEID information to a switching network element. According to the network attachment method and the system, the conventional attachment process is modified to a certain extent, scenes especially represent high efficiency after the replacement of an MME, the signaling cost during the replacement of the MME is omitted, the process of establishing an S5/S8 bearer is omitted via the merging of the mobile management entity MME and the GW function, corresponding process and the process of address distribution are saved, and the end-to-end time delay performance in the novel mobile network is enhanced.
本发明公开了一种网络附着方法及系统,包括:CN控制器接收到经由无线接入网RAN控制器透传的、由终端发送的附着请求;CN控制器对终端进行鉴权并完成服务质量QoS处理,为终端建立S1承载以及无线承载;CN控制器向交换网元下发用于数据传输的网元节点的地址和隧道端点标识符TEID信息。本发明的网络附着方法和系统,对传统附着流程给出一定修改,对于更换MME后的场景尤其表现出高效性,省去了在更换MME时的信令消耗,并且由于移动性管理实体MME和GW功能的合并,省去了S5/S8承载建立的过程,节省了相应的流程以及地址分配过程,提高了新型移动网络下的端到端时延性能。
