The invention provides for path optimization for routing of a communication session in a network having a plurality of core networks coupled to a plurality of access networks. Both a core network and an access network perform the path optimization by determining a plurality of possible paths to a plurality of target access points to form a target matrix, determining a corresponding route preference factor for each possible path of the target matrix, and selecting, from the target matrix, a possible path having an optimal route preference factor. An overall or complete path, for routing of the communication session, is then determined either by combining the selected possible paths, or by selecting one possible path as a complete path. The route preference factor, for each possible path, is determined based upon various routing variables, such as quality of service, bandwidth for the communication session, route complexity, interconnect cost, routing cost; resource loading, resource availability, and operator preference for traffic biasing.

A wireless communication system () uses communications bridging functions to establish redundant communication paths () between redundant radio access network session clients (), a core system and a base transceiver station (). The system () carries out a handoff or reallocation of call control from one of the radio access network session clients () to another one of the radio access network session clients () based on the integrity of the redundant communication paths ().

A gateway () and method for routing calls for a wireless communication unit () via a selected network () comprises an access point () supporting a wireless LAN and a modem () for wireless connections to a wireless WAN and an interface with a wired local loop (). The methodology involves using a first network, such as a local loop if available and a second network, such as a packet data WAN otherwise as well as maintaining the busy status of the first network via the second network.
