Problems solved by technology

[0005] The existing technology only has the process of transferring the media in the normal receiving / sending state between different terminal devices, but does not provide the process of transferring the media in the hold state between different terminal devices. (sendonly), only receive (recvonly), not send and not receive (inactive), for example, A answers the call of C during the call with B, and the call between A and B is on hold

Embodiment 1

[0024] Embodiment one, see figure 2 Detailed description, figure 2 It is a schematic flow chart of the method in this embodiment.

[0025] Step 301: Receive a transfer request message sent by the first terminal, the transfer request message requests to transfer the media in the conversation between the first terminal and the peer terminal to the second terminal, and includes the information that will be in the hold state before the transfer after the transfer. An indication that the medium has changed to a continuing transfer state.

[0026] The transfer request message sent by the first terminal includes the requested behavior (transfer media to another device), media transfer target device, media information to be transferred (such as media type, media-associated dialogue), etc. Change the medium in the holding state before the transfer to the instruction of continuing the transmission state, so as to propose the requirement of continuing to transmit the medium in the ho...

Embodiment 2

[0040] Step 401: UE-1 decides to transfer the media in the session with the peer UE to UE-2, including the media in the hold state.

[0041] The media to be transferred may be one or more media, and may be part or all of the media in the session, which does not affect the implementation of the embodiments of the present invention.

[0042] Step 402: UE-1 sends a transfer request message (REFER) to the SCC AS through the CSCF, requesting to transfer the media to UE-2. The transfer request message contains an instruction to change the media in the holding state before the transfer to the continuing transmission state after the transfer.

[0043] UE-1 may send a transfer request message to the SCC AS through the CSCF. CSCF provides the core IMS session control function in the IMS network. According to its position and function, it can be divided into proxy call session control function entity (P-CSCF), serving call session control function entity (S-CSCF), inquiry call session co...

Embodiment 4

[0080] Step 501: Terminal A talks to terminal B.

[0081] Step 502: During the call between terminal A and terminal B, an incoming call from terminal C of the third party is answered.

[0082] At this time, terminal A puts the call with terminal B on hold, that is, the call between terminal A and terminal B is on hold.

[0083] Step 503: Terminal A transfers the call with terminal B to terminal D, and terminal D and terminal B continue the call.

[0084] Terminal A and terminal D may be different terminals, for example, terminal A may be a mobile phone, and terminal D may be a landline phone. Terminal A and terminal D may belong to the same user or different users, which does not affect the realization of the embodiment of the present invention.

Abstract

The embodiment of the invention discloses a method, a device and a system for transferring media. The method comprises the following steps: the transfer request message sent by a first terminal is received; the transfer request message requests that the media in the dialog between the first terminal and a corresponding terminal is transferred to a second terminal, and the media contains the indication that the media in keeping state before being transferred is changed into media in continuous transmitting state after being transferred; a dialog with the second terminal is built; the media is transferred to the second terminal; and the media includes the media in keeping state before being transferred. The media in keeping state can be transferred between different terminals and continuously transmit by means of the message containing the indication that the media in keeping state before being transferred is changed into media in continuous transmitting state after being transferred.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for transferring media. Background technique [0002] When an Internet Protocol-based multimedia subsystem (Internet Protocol Multimedia Subsystem, IMS) session is transferred between different terminal devices, in order to provide a good user experience, it is required that the session media stream (media) also remain continuous during the transfer process. [0003] see figure 1 , figure 1 It is a schematic diagram of transfer of session media between different terminal devices, 101 terminal-1 and 103 peer terminals conduct a session; when 101 terminal-1 needs to transfer the session to 104 terminal-2, 101 terminal-1 calls the session control functional entity (Call Session Control Function, CSCF) sends a transfer message (REFER) to 102 Service Centralization and Continuity Application Server (Service Centralization and Continuity App...
