摘要： 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.
摘要翻译：本发明的基本概念是扩展针对SR-VCC和SCC AS的增强型MSC服务器的能力，以支持“会话转移撤销”过程。为了允许这样的过程，设想为SR-VCC增强的MSC-Server涉及来自源RAN的呼叫的切换过程，例如， E-UTRAN / UTRAN HSPA，到目标RAN，例如。 GERAN / UTRAN CS发送针对目标RAN执行用于所述呼叫的会话传送的指示。一旦MSC-Server从源RAN的移动性管理实体（例如MME或SGSN）接收到已经发起会话转移指示的重定位请求被取消的指示，则MSC服务器可以发送会话传送应该在执行会话转移的IMS中取消SCC AS。

摘要： A method is provided of performing a handover with Single Radio Voice Call Continuity, SRVCC, of a telecommunications session from a User Equipment, UE accessing an IP Multimedia Subsystem, IMS, network via a Circuit Switched, CS, access network to a target Packet Switched, PS, access network. The method includes receiving a handover request from the CS access network to transfer the session and determining that the telecommunications session comprises data media in addition to, or without, any audio media. The ability to perform the handover with SRVCC for the data media is determined. Bearer resources for the session when handed over to the PS access network are allocated, including a data media bearer and, if there is any audio media in the session an audio media bearer. The session is transferred from the CS to the target PS access network.

摘要： A method is provided for updating or handling the update of a media path between a first user terminal and a second user terminal in a telecommunications network. The media path includes one or more gateway nodes. Each gateway node includes a gating function for gating media packets. Each gating function has an associated controlling function for controlling the gating function. A message is received (S5) at a gating function from its associated controlling function indicating that an update of the gating at the gating function is required. The gating function arranges (S6) for a new gating, appropriate for the new or updated media path, to be opened while keeping the old gating, appropriate for the old or previous or existing media path, open (S8). The gating function determines (S7) when the media has been switched, or at least is likely to have been switched, to the new path. When it is so determined, the gating function arranges for the old gating to be closed (S9).

摘要： A mechanism is presented for performing a session transfer with Single Radio Voice Call Continuity, SRVCC, from a Packet Switched, PS, access to a Circuit Switched, CS, access of a telecommunications session that has been established over the PS access via an IP Multimedia Subsystem, IMS, network. The method includes receiving a request for the transfer of the session to the CS access. An indication of an already- seized media gateway, MGW, that has been established for use in one or more other sessions over the CS access is obtained from the IMS network. A MGW is selected as a Mobile-Media Gateway, M-MGW, for the session based on the obtained indication. Allocation of resources for the session in the CS access network is initiated, including specifying the MGW to be used as the Mobile-Media Gateway, M-MGW. Transfer of the session to the CS access is then initiated.
