Abstract:
The basic concept of the invention is to expand the capabilities of the MSC Server enhanced for SR-VCC and of the SCC AS to support a “session transfer revocation” procedure. To allow for such procedure it is envisaged that a MSC-Server enhanced for SR-VCC being involved in a Handover procedure for a call from a source RAN, e.g. E-UTRAN/UTRAN HSPA, to a target RAN, e.g. GERAN/UTRAN CS, sends an indication that a session transfer for said call should be performed towards the target RAN. Once the MSC-Server receives from a mobility management entity, such as MME or SGSN, of the source RAN an indication that a relocation request having initiated the session transfer indication is canceled, the MSC-Server may send an indication that the session transfer should be cancelled towards the SCC AS in the IMS which has performed the session transfer.
