Abstract

The ever growing multimedia services in the telecommunication industry have congested the mobile cellular networks in proportions never witnessed before. This worrisome trend has resulted in degraded services especially during handover in networks as bandwidth is limited. To avoid starving critical servicesafter handover, bandwidth has to be shared fairly. Specifically, users requiring more bandwidth for transmission should not be limited by bandwidth, conversely, those requiring less bandwidth should not be over allocated. A worthwhile strategy to these challenges would be a properly designed admission control that meets Quality of Service (QoS) requirements. An admission control ensures that the acceptance of a new traffic into a network cell does not deny services to already established traffic and that the network cell can satisfy its different QoS requirements. The paper presents the design, implementation and performance of an admission control algorithm based on bandwidth broker that provides QoS of multimedia traffic in a cellular network during handover. The algorithm manages multimedia traffic through Differentiated Service (DiffServ) policies. Instead of having admission mechanisms in all core routers processing traffic requests as in Integrated Service (IntServ), a centralized Bandwidth Broker (BB) is preferred. The bandwidth is partitioned between different multimedia traffic.
