Load balancing for cellular/WLAN integrated networks
– The interworking between the third-generation (3G) cellular network and wireless local area networks (WLANs) is one of the promising approaches to next-generation wireless networks, which can exploit the complementary advantages of the cellular network and the WLAN. Resource management for the cellular/WLAN integrated network is an important open issue that deserves more research efforts. In this article, we present a policy framework for resource management in a loosely-coupled cellular/WLAN integrated network, where load balancing policies are designed to efficiently utilize the pooled resources of the network. A two-phase control strategy is adopted in the load balancing policies, in which call assignment is used to provision statistic quality of service (QoS) guarantee during the admission phase, and dynamic vertical handoff during the traffic serving phase is used to smooth the performance variance. Numerical results are presented to demonstrate that the proposed load balanc...
