摘要:
A method, equipment, and a mobile communication system for realizing explicit call transfer are provided. The method for realizing explicit call transfer includes the following steps. A service centralization & continuity application server (SCC AS) receives a call request sent by a second user equipment (UE), and sends the call request to a third UE, in which an instruction for replacing a call between a first UE and the third UE is carried in the call request. A message returned by the third UE according to the call request is received, and the third UE is controlled to establish a connection with the second UE and to break a connection with the first UE. The third UE is an IP multimedia subsystem centralized service user equipment (ICS UE).

A method and a device for holding calls between networks are disclosed herein. The method includes: receiving a call hold request sent by a UE in a CS network, where the call hold request carries an indication that the UE in the CS network will continue sending media streams; and instructing a peer device to keep receiving the media streams from the UE in the CS network and stop sending the media streams. In the technical solution under the present invention, the UE in the CS network partially releases the radio resources after initiating the call hold operation, and therefore, the UE in the CS network can play local media files to the peer device after the call is held, thus saving network resources and improving the user experience.

A method, device, and system for transferring a Service Control Signalling Path are provided. The method for transferring a Service Control Signalling Path includes: establishing a connection with an opposite end by a User Equipment (UE), where the UE uses a Circuit Switched (CS) bearer in a CS network and a Service Control Signalling Path in a first Packet Switched (PS) network; sending a transfer request via a second PS network, to instruct a network side to transfer the Service Control Signalling Path according to the transfer request. Thus, the UE can replace a current Gm reference point with a Gm reference point of a new and available PS network when the PS network where the current Gm reference point is located is unavailable, so as to ensure smooth data transmission.

A call transfer method, system, and device are provided. The method includes obtaining information that the mobile switching center (MSC) of a called user equipment (UE) executes a call transfer service, and instructing the MSC of the called UE to send a call request to a third party UE according to the call originating process of the called UE.

Embodiments of the present invention disclose a session processing method, device, and communication system. The session processing method includes: when a first User Equipment (UE) is to set up an IP Multimedia Subsystem (IMS) session with a second UE, triggering setup of an unstructured supplementary service data (USSD) transaction between a Circuit Switched (CS) network and the first UE; and sending, by using the USSD transaction, an I1 protocol message used to bear IMS session control signaling. With the technical solutions of the present invention, when a UE is to set up an IMS session, a USSD transaction is set up between the UE and the CS network; I1 protocol messages exchanged between the UE and the Service Centralization and Continuity (SCC) Application Server (AS) (SCC-AS) are sent reliably by using the USSD transaction, which facilitates reliable control over IMS services.

A multi-session transfer method, a call control device, and a Service Continuity and Continuity Application Server are disclosed. In the embodiments of the present invention, in a multi-session cross-network transfer process, if a second session to be transferred includes video media, a Mobile Switching Center (MSC) server judges capabilities of a current network. If the current network is incapable of transmitting video media, the MSC server sends a request for transferring voice media of the second session to be transferred. The SCC AS receives the transfer request, and converts the second session to be transferred into voice session for transferring or releases the second session to be transferred, and therefore, the problem in the prior art of incapability of transferring the session is avoided, and the cross-network multi-session service transfer is improved.

Embodiments of the present invention disclose a method, an apparatus, and a system for service control via an I1 interface. The method includes: sending a Session Initiation Protocol Invite message to a user equipment through a Gm interface; if receiving a response message returned by the user equipment, where the response message indicates that the user equipment chooses to use a circuit switched bearer and use an I1 interface for control, sending an I1 Invite message to the user equipment through the I1 interface, where I1 Invite message carries information indicating that Gm interface control falls back to the I1 interface control and information used to associate the Session Initiation Protocol Invite message.

The present invention discloses a session transfer method, a device and a system, which relate to the communication field and are used to solve the problem that a conference to which a session belongs cannot be controlled after the session is transferred. The technical solution provided in the present invention includes: determining whether a User Equipment (UE) has at least one session belonging to a conference during a process that a session of the UE is transferred from a source network to a target network and sending information relevant to the conference to the UE or a Mobile Switching Center (MSC) server if the UE has at least one session belonging to the conference (102). The embodiments of the present invention can be applied in a wireless communication network.
