摘要

分布式数据查询策略及其结构(DDB结构)

与传统的HLR-VLR结构有很大的不同.本文提出了一种对DDB结构的性能估计方法

其基础是用户的移动性和呼叫特性的概率分布.本文对DDB结构的代价和呼叫传递时延等性能参数进行了研究

证明了DDB结构的性能优越性.

Abstract

The distributed database (DDB)architectures as well as their data query strategies

are quite different from traditional HLR-VLR structure.This paper presents a methodology for evaluating hierarchical DDB architectures

based upon users' pdf of mobility and call characteristics.The main interests to DDB's performance are cost and call delivery delay

and research shows they are much better than those in a HLR-VLR structure.
