Mobility management for cellular telephony networks

Abstract

Cellular telephony provides voice and data services to mobile users. To deliver these services, the cellular network can track the locations of the users, and can allow user movement during the conversations. It achieves these capabilities through small-scale (handoff) and large-scale (roaming) mobility management. In this tutorial, the authors describe mobility management in cellular networks, including the details of different handoff schemes, location-tracking schemes, and call-delivery procedures.
