Abstract (en)

[origin: WO2012000535A1] A method for a Mobile Control Node, MCN, supporting handover of a packet switched, PS, voice call of a given user entity anchored in a IP Multimedia Subsystem (IMS) to a circuit switched, CS, voice call, by using a Single Radio Voice Call Continuity, SRVCC, function, whereby, - after handover from PS to CS (102) voice call pertaining to a user entity, UE, which UE is in a suspended mode (305, 206/209/303), and upon receiving a SRVCC CS to PS resume request message (107) from a mobile switching centre, MSC, - issuing an explicit / implicit resume message (109, 306) to a packet gateway (PGW) node or a serving gateway (SGW) node, causing the UE to resume PS services (110). Further a method for a Mobile Switching Centre (MSC) supporting handover of a packet switched, PS, voice call of a given user entity (UE) via an SP Multimedia Subsystem (IMS) to a circuit switched, CS, voice call, by using a Single Radio Voice Call Continuity, SRVCC, function, wherein - after handover from PS to CS (103), and after detecting hang up or dropped call (106) issuing (209) a SRVCC CS to PS resume request message (107) to a MCN, thereby effecting the user entity to resume PS services of the voice call for a given user entity (UE).
