摘要

文章研究了长期演进（LTE）非接入层身份认证、演进型分组系统（EPS）安全上下文建立以及启用过程

提出了一种改进方案。该方案减少了系统的信令开销

降低了过程处理时延。通过对新旧方案在实现效率方面的对比

分析了两种方案的通信次数、延迟时间

说明新方案具有节约链路资源和缩短过程处理时间的优点。

Abstract

In this paper

the authentication in the LTE non-access-stratum and the establishment and use of the security context of an Evolved Packet System（EPS） are studied and an improvement scheme presented.In this scheme

the system signalling overhead is decreased and the time-delay processing reduced.By comparing the new scheme with the conventional one in implementation efficiency

the times of communication and time delay in these two schemes are analyzed

indicating that the new one is better in terms of link resource saving and processing time reduction.
