摘要： The invention relates to methods and nodes for supporting a session transfer, for a user equipment, from a circuit switched network to a packets witched network. According to one aspect a method for operating a control node of a core network is provided. The method comprises the steps: requesting from a radio access network of the circuit switched network information on whether a capability of the user equipment related to the session transfer are compatible with a network configuration related to the session transfer; receiving from the radio access network an indication whether the capability of the user equipment and the network configuration are compatible; determining whether to indicate that the session transfer is supported by using the received compatibility indication; and setting an indication whether the session transfer is supported according to the determination.
