Claim:
1. A method for improving session continuity for a terminal in a serving communication network distinct from a home communication network of the terminal, wherein the serving communication network comprises a session transfer node for transferring sessions each comprising signaling data and media data from a first access network of the serving communication network to a second access network of the serving communication network, the method comprising: routing signaling data of a session of the terminal between the first access network and the home communication network via the session transfer node, wherein the session of the terminal utilizes the home communication network; receiving a session transfer request requesting the transfer of the session from the first access network to the second access network for the terminal; transferring, in the serving communication network, the session from the first access network to the second access network; and routing the signaling data of the session of the terminal between the second access network and the home communication network via the session transfer node.
