SINGLE RADIO VOICE CALL CONTINUITY (SR-VCC)
Abstract:
The present invention discloses a node (207, 217) for achieving co-existence of single radio voice call continuity, SR-VCC, solutions in a communication system between a source cell of a first radio access network that supports packet switched voice and a target cell of a second radio access network that supports at least circuit switched voice. The node (207, 217) is operable to perform bearer splitting by separating voice bearers from non-voice bearers based on information about support for dual transfer mode, packet switched handovers and voice over internet protocol related enhancements in the target cell.
