摘要

本文提出了一种新的访问者位置寄存器(VLR)故障恢复方案,称为个人通信业务(PCS)的需求重注册。在该方案中,VLR在故障后向所有移动台广播重新注册请求。当MS接收到重新注册请求时,它向VLR发送注册消息以恢复位置记录。我们通过调查重新注册在第一次MS呼叫终止发生之前如何有效地恢复MS的位置记录来研究需求重新注册的性能。结果表明,需求重配可以有效地从VLR故障中恢复。

Demand re-registration for PCS database restoration
In this paper, we propose a new visitor location register (VLR) failure recovery scheme called demand re-registration for personal communications services (PCS). In this scheme, the VLR broadcasts a re-registration request to all mobile stations (MSs) after the VLR failure. When an MS receives the re-registration request, it sends a registration message to the VLR to recover the location record. We study the performance of demand re-registration by investigating how effectively the re-registration can recover the location record for an MS before the first MS call termination occurs. Our results indicate that demand re-registration can effectively recover from VLR failure.
