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).
