摘要

位置管理是移动通信领域的一个具有挑战性的问题

涉及到位置更新和位置查找操作.在现行蜂窝系统的位置管理策略(简称"基本策略")中

一旦移动台越区

就需要进行位置更新.由于移动台的越区具有局部性

基本策略会造成系统资源的极大浪费.因此

降低位置管理的费用成为移动通信领域的一个研究热点.该文给出不需要进行位置更新的环状搜索位置管理策略(简称"环状策略")

并推导出搜索位置区平均层数的一个公式

然后利用这一公式对基本策略、指针推进策略与环状策略的费用进行了对比研究

得出:在一定条件下

环状策略的费用要比基本策略及基本指针推进策略小.

Abstract

Location management

which consists of location update and location query

is a challenging topic in mobile communication.The basic location management scheme of personal communications services (PCS's) networks requires that location update be initiated whenever a mobile crosses the boundary of location areas.Obviously

this scheme is likely to waste the system resources due to the locality of mobiles' roaming.Therefore

reducing the cost of location management has become a hotspot of mobile communication.A location management schema with ring search (Ring Schema for short) was conceived

where no location update is needed.Additionally

a formula of the layer number of the location areas queried by Ring Schema was derived.According to this formula

the cost of Ring Scheme

on certain conditions

is less than both the cost of the basic scheme and that of the basic pointer forwarding schema.
