摘要

A method for improving session continuity for a terminal (204') in a serving communication network (202') distinct from a home communication network (200') of the terminal (204'), wherein the serving communication network (202') comprises a session transfer node (208') for transferring sessions each comprising signaling data and media data from a first access network (210') of the serving communication network (202') to a second access network (212') of the serving communication network (202') comprises the following: Routing signaling data of a session of the terminal (204') between the first access network (210') and the home communication network (200') via the session transfer node (208') in the serving communication network (202'), receiving a session transfer request requesting the transfer of the session from the first access network (210') to the second access network (212') for the terminal (204'), and transferring the session from the first access network (210') to the second access network (212'), and routing the signaling data of the session of the terminal (204') between the second access network (210') and the home communication network (200') via the session transfer node (208').
