“…In [16], the two-level forwarding pointer scheme has been proposed from per-user forwarding pointer scheme to reduce the cost of signaling traffic. When an MT moves from its current LA to another LA the local switch that acts as a parent of those two MSCs maintains this movement in its memory (cache entry).…”

Reducing the volume of location updates and cost of searching for location information are two important issues for tracking mobile users in personal communication systems. Many approaches have been proposed to improve both the location update traffic and searching costs. Some of these approaches can reduce access cost and some other approaches can reduce the location update cost and location update rate. In this paper, we shall propose a new approach for reducing both location update cost and searching cost (for finding mobile users location information). The new scheme called Virtual Overlap Region with Forwarding Pointer (VORFP) uses the forwarding pointer and the virtual overlap region concepts. The virtual overlap region technique is a good method for reducing the location update traffic, especially when a user backs and forths between adjacent cells. Our performance evaluations show that VORFP can significantly reduce searching cost and update cost.

“…Since LA 17 is in OR 12 = {LA 6 , LA 7 , LA 11 , LA 12 , LA 13 , LA 16 , LA 17 }, the LA ID field in VLR 12 is changed from 17 to 12.…”

The cellular principle is an effective way to guarantee efficient utilization of the offered radio band. Although PCS networks use the cellular principle, the next generation of PCS networks needs more improvements in location management to face the increased number of users. Both an Enhanced Profile- Based Strategy (EPBS) for small-scale roaming and a Caching Two-Level Forwarding Pointer (C2LFP) strategy for large-scale roaming have been proposed. This chapter introduces a model that unites the above two strategies. The idea behind this model is based on applying those two location management strategies and specifying the physical parameters of PCS networks from mobility management’s point of view so that the underlying solutions can be more cost effective for location management. An evolutionary method using a constraint Genetic Algorithm (GA) has been used to achieve network parameters optimization. For convenience, we selected the planning problem with an appropriate set of parameters to be treated both genetically and analytically. Thus one can easily verify accuracy and efficiency of the evolutionary solution that would be obtained from the genetic algorithm. For more realistic environments, GA could be used reliably to solve sophisticated problems that combine the small-scale and large-scale roaming parameters of PCS networks. A case study is presented to provide a deep explanation of the proposed integration approach.
