Look-ahead channel reservation and borrowing in cellular network systems

Abstract

This paper addresses the channel resource management problem for the cellular wireless network, under various traffic load conditions. Channel borrowing, a critical function in the effective management of cellular networks, is known to offer key performance benefits under hot spot situation. We propose a new channel borrowing approach, termed as LCRB (Look-ahead Channel Reservation and Borrowing)-where the key ideas include the ability to reserve a set of channels for different neighboring cells according to their traffic profile, and to conduct lookahead channel borrowing to provide channel distribution in anticipation of a forthcoming hot spot. The main benefits include the timeliness (i.e., reduced delay) of channel borrowing which can assist to meet deadlines of hard real-time message and to reduce the waiting time of uprising call. Simulation has been conducted to demonstrate the benefits.
