Definition

When the cellular networks are interconnected with the wireless local area networks (WLANs), there is a two-tier overlaying structure which offers both cellular access and WLAN access to a dual-mode mobile device within the WLAN-covered area. Ubiquitous coverage is provided by the cellular network (higher-tier), while WLANs (lower-tier) are deployed in disjoint hot-spot areas. Then, there comes the network selection problem of how to properly admit incoming traffic to the cell or WLAN. Specifically, a preferred target network, either a cellular cell or a WLAN, should be first selected based on various decision criteria by taking into account factors such as service type and network conditions of the two networks. A service request rejected by its first-choice network can just leave the system or further try to access the other network.
