Mobility management in next-generation wireless systems

Abstract

This paper describes current and proposed protocols for mobility management for PLMNbased networks, Mobile IP, Wireless ATM, and Satellite networks. The integration of these networks will be discussed in the context of the next evolutionary step of wireless communication networks. First, a review is provided of location management algorithms for PCS implemented over a PLMN network. The latest protocol changes for location registration and handoff are investigated for Mobile IP, followed by a discussion of proposed protocols for Wireless ATM and Satellite networks. Finally, an outline of open problems to be addressed by the next generation of wireless network service is discussed.
