Embodiment 1
[0128] Such as Figure 8 As shown, UE-A establishes a voice session in the IMS domain and remote UE-B. When UE-A decides to switch the session from the IMS domain to the CS domain, UE-A and the network realize this single-mode service continuity In this process, the remote UE-B URI is brought to the MSC. Specific steps are as follows:
[0129] Step S802: UE-A establishes a voice session with the remote UE on the PS network (LTE / SAE), and the session is anchored on the ATCF / AGW of the visited network, where the ATCF is responsible for the signaling part, and the AGW is responsible for the media part; The session is processed by the SCC AS in the home domain of UE-A, and a remote branch is established with the remote UE; the network signal strength changes due to the location of UE-A and other reasons, UE-A interacts with the PS network, and the PS network decides to initiate Single-mode voice conversation service continuity process;

Embodiment 2
[0146] Such as Picture 9 As shown, UE-A establishes a voice session in the IMS domain and remote UE-B. When UE-A decides to switch the session from the IMS domain to the CS domain, UE-A and the network realize this single-mode service continuity The process of bringing the remote UE-B URI to the MSC during this process includes the following steps:
[0147] Step S902: UE-A establishes a voice session with the remote UE on the PS network (LTE / SAE), and the session is anchored on the ATCF / AGW of the visited network, where the ATCF is responsible for the signaling part, and the AGW is responsible for the media part; The session is processed by the SCC AS in the home domain of UE-A, and a remote branch is established with the remote UE; the network signal strength changes due to the location of UE-A and other reasons, UE-A interacts with the PS network, and the PS network decides to initiate Single-mode voice conversation service continuity process;

Embodiment 3
[0165] Picture 10 It shows that UE-A has established a voice session in the IMS domain and remote UE-B. When UE-A decides to switch the session from the IMS domain to the CS domain, UE-A and the network realize this single-mode service continuity The process of bringing the remote UE-B URI to the MSC during this process includes the following steps:
[0166] In step S1002, UE-A establishes a voice session with the remote UE on the PS network (LTE / SAE), and the session is anchored on the ATCF / AGW of the visited network, where the ATCF is responsible for the signaling part, and the AGW is responsible for the media part; The session is processed by the SCC AS in the home domain of UE-A, and a remote branch is established with the remote UE; the network signal strength changes due to the location of UE-A and other reasons, UE-A interacts with the PS network, and the PS network decides to initiate Single-mode voice conversation service continuity process;
