摘要
A method for exchanging a packet-oriented communications service (ps - d) to a line-oriented communications service (cs - d), and vice versa in a mobile communication system (mks), wherein the mobile communication system (mks) at least one on the ‘ internet protocol multimedia subsystem " based services communication system (ims) with a first as a call state control function - unitary services expensive unit (cscf), at least a packet-oriented switching network (ps) and at least one line oriented switching network (cs) with a second services expensive unit (gsmscf), characterized in that, in order to change from the packet-oriented communications service (ps - d) on the line-oriented communications service (cs - d) or from the leitungsorierttierten communications service (cs - d) to the packet-oriented communications service (ps - d) between the call state control function - unit (cscf) and which, as a global system for mobile communications / service control function - unit designed second services expensive unit (gsmscf) to set up a signaling connection (sv) is built up, by which at least one of change information (wi, wi '') is transmitted.
