Abstract
Network nodes in a source and a target communication system, and methods therein for supporting hand over to the target communication system, of a mobile terminal supporting Packet Switched-to-Circuit Switched, PS-to-CS, hand over. The method in the source communication system comprises, when requesting resources for hand over of a mobile terminal engaged in a conversational call to a target node in the target communication system, signaling a first request for PS resources to the target communication system, indicating a bearer B, used for the conversational call, and further signaling a second request for CS resources to the target communication system, indicating the bearer B. Thereby, the target communication system is enabled to decide whether a PS-to-CS HO or a PSHO of the bearer B should be performed.
