摘要: 针对现有3G系统传递过程中系统开销较大的问题,提出一种改进的基于网关位置寄存器(GLR)的3G网络呼叫建立机制。利用GLR在3G网络中的作用,采用本地路由和缓存策略改进现有3G系统中的呼叫建立机制。仿真结果表明,在该机制中,存在一个最优的移动域门限值来平衡位置更新和终端寻呼的代价,从而获得位置管理总代价最小化。

Abstract: Aiming at the problem of the big system cost of the call delivery process in the 3G network, this paper proposes an improved call setup mechanism, which takes the local routing and caching. The present call setup mechanism is optimized. Simulation results show that there is an optimal threshold to balance location update and terminal paging cost to obtain the minimum total cost of location management, and the optimized mechanism can reduce the system cost of the call delivery process effectively.

Key words: 3G network, Gateway Location Register(GLR), local routing, call setup, location management
