摘要： Method for supporting network based mobility for a mobile terminal in an IMS (IP Multimedia Subsystem) architecture, wherein said mobile terminal is connected to a femto cell or to a macro cell - source cell - and wherein a handover of an actual session of said mobile terminal is performed to another femto cell or macro cell - target cell -, wherein said femto cells and said macro cells are equipped with or are connected to an eMSC-server (Mobile Switching Center Server enhanced for IMS Centralized Services) function, and wherein said source cell's eMSC-server function hosts a source user agent and said target cell's eMSC-server function hosts a target user agent, is characterized in that said source user agent contacts said target user agent directly or indirectly prior to executing the actual handover, and wherein said source user agent prepares said target user agent together with the corresponding access network by exchanging handover related information.
