一种自适应位置更新方案

在移动通信的位置更新过程中,传统的静态位置区方案存在着缺乏变化的灵活性、边界振荡、信令负载过于集中等问题,本文提出了一种新的自适应位置更新方案,采用不同级别的位置区,位置区的选择根据移动台当时的移动和呼叫情况,按照使位置更新和寻呼的无线信令总代价最小的原则确定.该方案可有效地解决静态位置区的各种问题,并能方便地与其它位置区方案切换.

A Scheme of Personalized Adaptive Location Areas

The traditional static location area scheme used in the location updating procedure of mobile communications has many problems,such as lack of flexibility,MS oscillating between LA borders,focused signaling load on border cells,etc.In this paper we present a new adaptive location updating scheme,which can solve the above problems,and can change easily to other LA schemes.The scheme uses multi-level LAs,selected according to single MS's mobility and call characteristics,to make the best tradeoff between wireless signaling cost of location updating and paging.
