摘要：

A PCS network constantly frocks the locations of the mobile stations so that incoming calls can be delivered to the target mobile stations. In general, a two-level database system is used to store location information of the mobile stations. When the location databases Fail, incoming calls may be lost. This article describes the standard GSM database failure restoration procedure which reduces the number of lost calls. Then we propose an efficient VLR identification algorithm for the HLR failure recovery procedure, which utilizes mobile station movement information to speed up the recovery procedure.
