摘要

移动跟踪关注的是在无线网络服务的区域内寻找移动用户。跟踪移动用户的两个基本操作,位置更新和分页,构成了网络上必要的开销。系统设计阶段的一个中心问题是位置区域规划:将服务区域最佳地划分为位置区域,以最小化更新和分页的总成本。本文研究了完全齐次流量,即每时间单位在任何一对小区之间移动的移动用户数量是一个常数,并提出了一个多项式时间近似方案。

Location Area Planning with complete homogenous traffic
Mobility tracking is concerned with finding mobile users within the area serviced by the wireless network. The two basic operations for tracking mobile users, location updating and paging, constitute a necessary overhead on the network. A central problem in the design phase of the system is Location Area Planning: optimally divide the service area into location areas to minimize the total cost of updating and paging. This paper examines complete homogeneous traffic, i.e., the number of mobile users that move between any pair of cells per time unit is a constant, and presents a polynomial time approximation scheme.
