摘要: 在本论文中,我们提出了应用在多层次个人通信服务系统 (multi-tier
PCS systems) 中可能的两种多层次资料库系统(multi-tier database
systems)架构,分别是集中式 的架构(Centralized HLR Architecture,
CHA)和非集中式的架构(Decentralized HLR Architecture, DHA)。 我
们也提出了在这两种架构中如何管理以及处理和移动有关的 运作,亦
即注册(registration)、取消注册(deregistration)、呼叫的拨接(call
origination)以及呼叫的递送(call termination)。在一些假设下,我们
导出了对于 系统效能评估的数学分析式,评估的项目包括查询所需的
反应时间(query response time)、更新所需的反应时间(update
response time)以及在这多层次资料库系统网路 中传输的信号量(
traffic volume)。最后我们经由分析结果来比较这两种架构的优劣。 从
我们的分析结果可得知,除了在更新的反应时间这一项以外,非集中式架
构(DHA)的 效能要比集中式架构(CHA)来的好。
In this thesis, we propose two possible multi-tier database
system architectures, Centralized HLR Architecture
(CHA) and Decentralized HLR Architecture (DHA) for
multi-tier PCS systems. We also propose mobility
management strategies which deal with mobility-related
operations (i.e., registration, deregistration, call
origination, and call termination) for the two
proposed architectures. Under some assumptions,
mathematical analysis are derived on the performance
metrics, which include the query response time, the update
response time, and the traffic volume produced in the
two architectures. Finally, the analysis results of CHA and
DHA are made, and the pros and cons of the two proposed
architectures are figured out. From the analysis results, it is
found that the DHA performs better than the CHA except the
update response time.
