An efficient location management scheme for PCS networks

This paper investigates a new location management scheme for improving the basic location strategy proposed in the IS-41 standard. This scheme essentially consists of adding to the current network architecture a pointer table and a location data table. A pointer table is provided for each location area (LA) where it tracks the MUs that have moved out of this LA. The location data table located on a local signal transfer point (LSTP) node contains the data location of the MUs frequently called from the LAs connected to this LSTP. These two tables contribute to reduce significantly the cost of both location update and call delivery procedures. Computational results indicate that the amount of reduction obtained depends on the value of the call to mobility ratio of the MUs.
