摘要： Provided are a method and signaling gateway for establishing an optimized media path applied in an IMS network. The method includes: during the process of forwarding a session description protocol (SDP) request and response, when receiving a SDP response of a first session, a first ALG judging that there is an optimized media path between itself and a second ALG, then when sending the SDP response of the first session, including indication information in the send SDP response; the first ALG sending a SDP request with the target being the second ALG; and after having received the SDP response of the first session including the indication information or after having received the SDP request with the target being the second ALG and the SDP response of the first session including the indication information, the second ALG sending the SDP response of the first session.

摘要： The present invention discloses a method and a system for implementing single radio voice call continuity (SRVCC), and said method includes: an ALG sending number information and/or identifier information if the ALG to a SCAS via a signaling message; said SCAS judging whether the number information and/or identifier information of the ALG are identical with the last used REFER number information or not, and if not, said SCAS notifying a PS or CS network control entity of the number information and/or identifier information of the ALG; alternatively, said SCAS notifying the PS or CS network control entity of the number and/or identifier information of the ALG. The present invention implements to dynamically select the ALG as a REFER operation entity to implement SRVCC, and solves the problem that a REFER request cannot be sent to an appropriate ALG since this ALG cannot be dynamically determined.
