Handoff and Radio Resource Management in Cellular Systems

Abstract

To a wireless user, dropped calls, blocked calls, and calls riddled with static are unacceptable. Users expect to remain connected while traveling through cells of a service area. Users also expect to be able to make calls at any time and to have good, clear connections. These user demands are addressed through the management of radio resources. Handoff is an important aspect of the radio resource management. Handoff makes a continuous connection possible by transferring a mobile user from one cell to another. Handoff also determines how many calls can be served in a given area and the quality perceived by users. Thus, efficient handoff algorithms are essential for preserving the capacity and quality of service of wireless communication systems.
