Abstract
In a personal communications services system, it is required to locate the destination portable when an incoming call arrives. We propose a simple location tracking scheme called the T-threshold location. cache scheme. In the scheme, a threshold T is used to determine whether a cached location record is obsolete. When the incoming call frequency changes, this scheme adaptively modifies the threshold to yield the best performance. An analytical model is proposed to study the T-thresbold scheme. The analysis indicates that the T-threshold scheme effectively reduces the network traffic compared to the IS-41 scheme.
