Modeling and Analysis of Mobility Management in Mobile Communication Networks

Abstract EN

Many strategies have been proposed to reduce the mobility management cost in mobile communication networks.

This paper studies the zone-based registration methods that have been adopted by most mobile communication networks.

We focus on two special zone-based registration methods, called two-zone registration (2Z) and two-zone registration with implicit registration by outgoing calls (2Zi).

We provide a new mathematical model to analyze the exact performance of 2Z and 2Zi.

We also present various numerical results, to compare the performance of 2Zi with those of 2Z and one-zone registration (1Z), and show that 2Zi is superior to 2Z as well as 1Z in most cases.
