A method in a communication system is disclosed. In the method a procedure for setting up a communication link between a first user equipment and a second user equipment via a communications network is initiated. Information regarding at least two modes of communication that can be used for communication via the communication link is signalled between the first and second user equipment. An indicator regarding a mode to be used for the communication is also signalled between the first user equipment and the second user equipment. After the signalling steps, a procedure for setting the mode of communication in accordance with the indicator is initiated in at least in one of the user equipment. According to an alternative embodiment signalling for reserving a possibility for at least tow different communication modes occurs between elements of the communication system.

Disclosed is a method of executing a handover in a system including a core network comprising two mobile services switching center. Both mobile services switching center can be accessed to by a cellular access as well as by a non-cellular access. The system further includes a terminal which can access to both mobile services switching center over the cellular access as well as over the non-cellular access. The method comprises the steps of handing over a call of the terminal to non-cellular access involving also a handover from a first one of said two mobile services switching center to a second one of said two mobile services switching center, and indicating in a message that the call of the terminal was handed over to non-cellular access, wherein said message is sent from the second mobile services switching center to the first mobile services switching center.
