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 interfacewith 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 WANotherwise as well as maintaining the busy status of the first network via the second network.

Method and gateway for controlling call routing

A services delivery element () forms an interface between an external element (such as an external end user's network feature server) and a communication network including both a core network () and an access network (). The services delivery element () provides access to the core network () and access networks () to which the external element is interfaced.

Method and apparatus for interfacing a network to an external element

A wireless communication system () uses communications bridging functions to establish redundant communication paths () between redundant radio access network session clients (), a core systemand 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 ().

High integrity radio access network client reallocation in a wireless communication network

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.

Segmented and distributed path optimization in a communication network

A communication system ( ) having packet and circuit switched networks ( and ) provides connection between at least a first and a second end users by establishing a call connection via a radio access network ( ), establishing a control channel associated the call connection between radio access network ( ) and packet switched network ( ) through a first packet switched connection, selecting one of packet and circuit switched networks ( and ) for establishing a traffic channel associated with the call connection, and routing the traffic channel through said selected network while maintaining the control channel through packet switched network ( ).
