Abstract:
A controller (118) controls functions related specifically to radiotelephone signalling in a communication system. The controller (118) is physically dislocated from a switch (112) which performs all necessary routing of voice information from radiotelephone system-to-radiotelephone system and radiotelephone system-to-public switched telephone system (PSTN, 100). The controller (118) interfaces the switch (112) via an ISDN-type connection, essentially accessing the switch (112) transparently. This transparent access allows for common, generic switches (Class 5 switches for example) having predetermined user features such as Call Waiting, 3-Way Calling, etc. to be employed. Users of the radiotelephone system (125), via radiotelephone signalling processing by the controller (118), can access and utilize the predetermined features of the switch (112) as required.

Abstract:
The invention provides for path optimization for routing of a communication session in a network having a plurality of core networks (110) coupled to a plurality of access networks (120). 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.
Abstract:
A communication system (100) having packet and circuit switched networks (102 and 101) provides connection between at least a first and a second end users by establishing a call connection via a radio access network (105), establishing a control channel associated the call connection between radio access network (105) and packet switched network (102) through a first packet switched connection, selecting one of packet and circuit switched networks (101 and 102) 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 (102).
