In the future wireless communication network, it is envisioned that both single-network and multi-homing services will co-exist. Hence, it is required to develop radio resource allocation algorithms that can support both service types. In this case, the radio resource allocation mechanism is to determine the optimal network assignment for MTs with single-network service and the corresponding bandwidth allocation for MTs with single-network and multi-homing services. In this chapter, we discuss how to achieve these objectives in a decentralized network architecture with call arrivals and departures. Concepts of call traffic load prediction and cooperative networking, presented in Chap. 3, are employed to enable vertical handovers for single-network calls in a seamless manner and to satisfy multi-homing calls required bandwidth in such a decentralized network architecture.
