An Intelligent PCS Location Tracking Strategy

Abstract

We propose a new method which aims at reduction of signaling overhead resulting form location tracking in PCS (personal communication systems). The key idea is taking the recent user movement information (i.e., last connection, etc.), which is called paging information record, into account to determine which location area to be paged first. Experimental results show that our method can significantly reduce location management’s signaling cost compared with existing methods. The overhead of our approach is the additional storage space required (for storing mobile host profiles and paging information records) in network databases and the additional processing time of profiles and paging information records. However, neither the storage nor the processing time of today’s memory capacity and processor speed as far as the reduction of signaling traffic implying more bandwidth available.
