Predictive load-sharing scheme in a microcellular radio environment

Abstract

In a metropolitan microcellular environment, the cell coverage zone can be highly irregular. Thus highly overlapping areas can result due to an attempt to achieve ubiquitous coverage. We propose a predictive load sharing (PLS) scheme to alleviate localised congestion by using the knowledge of users potentially entering and leaving a cell. We study the system in a linear bidirectional highway environment. Results show that load carried is increased and the handsoff failure rate is lowered compared to the Fixed Channel Assignment (FCA) scheme. A lower handsoff failure rate is a desirable since the forced termination of an existing call can be very annoying to a user.
