Abstract
The present invention provides a media sharing diversion method, comprising that: in the process of media sharing transmission, the present receiving terminal of media shared resource transmits sharing redirectional request message to transmitting terminal of media shared resource; the transmitting terminal transmits sharing diversion response message to the current receiving terminal; the transmitting terminal performs media negotiation with the objective terminal, and establishes media channel; the transmitting terminal transmits media shared resource to the objective terminal. Through the method of the invention, the transmission of sharing contents diverting from the current sharing receiver to a new sharing receiver is realized, and the current shared process is not interrupted. The said mechanism which is convenient for diverting from mobile phone terminal to PC client terminal, is convenient for performing storage or further process to media contents; when the current shared terminal is insufficient in power, the sharing contents is diverted to the other terminals without interrupting the current sharing transmission.
Description
Technical field
The present invention relates to a kind of medium and share method, especially a kind of in the shared transmission course of medium, carry out medium and share the method that shifts.
Background technology
Along with the broadband development trend of mobile communication system, new multi-medium data value-added service continues to bring out.The medium technology of sharing is exactly a typical broadband mobile multimedia technology, and this technology makes between the portable terminal, can set up media transmission channel at any time according to user's needs, and the content of multimedia on the portable terminal is sent to Correspondent Node.Shared content can be video, audio frequency, the picture that portable terminal is shot with video-corder in real time, also can be video, audio frequency and the picture of local storage.The medium sharing functionality comprises Signaling Layer function and Media layer function.The Signaling Layer function is used for carrying out the control of media resource, comprises: before the medium sharing channel was set up, the both sides that share can confirm terminal capability by signaling procedure, and medium are shared the signaling manipulation of setting up and cancelling.The Media layer function is used for carrying out the transmission of media resource.
As shown in Figure 1, it is the signaling process figure that existing medium are shared, and terminal A is to terminal B share media resource, and wherein terminal A is for sharing the transmission terminal of content, and terminal B is for sharing the receiving terminal of content, and concrete steps are as follows:
Step 11, terminal A and terminal B carry out terminal capability exchange, and whether support media are shared ability to confirm the other side, and to sharing the support situation of aspect abilities such as content encoding;
After step 12, the capabilities exchange success, terminal A sends to terminal B and shares initial request messages;
Step 13, terminal B confirm this shared initial request messages, if terminal B agrees to share the request of initiation, then send to share to terminal A and initiate response message, execution in step 14 then, if terminal B refuses this sharing request, then send to share and initiate refuse information to terminal A, finish;
After step 14, terminal A receive the shared initiation response message of terminal B, the media channel of foundation and terminal B, and need shared media resource to user B transmission based on this passage.
But existing medium technology of sharing is not supported in the shared procedure and shifts sharing content between different terminals.Under several scenes, need carry out the transfer that medium are shared at terminal room.Transfer to pc client such as sharing content from mobile phone terminal, so that media content is stored or further handled; Perhaps, during current shared terminal power shortage, wish that sharing transfer by medium realizes continuing shared procedure etc.
Summary of the invention
The purpose of this invention is to provide the transfer method that a kind of medium are shared, make in shared procedure, realize sharing transmission from the new shared recipient of transferring to of current shared recipient, and do not interrupt current shared procedure.
For achieving the above object, the invention provides a kind of medium sharing transfer method, comprising:
Step 1, in medium are shared transmission course, the current receiving terminal of medium shared resource sends shared redirect request message to the transmission terminal of medium shared resource, comprises identification information or the address information of sharing the target terminal that shifts in this shared redirect request at least;
Step 2, described transmission terminal send to described current receiving terminal shares transfer response message;
Step 3, described transmission terminal and described purpose terminal are carried out media negotiation, and set up media channel;
Step 4, described transmission terminal are to described purpose terminal transmission medium shared resource.
By medium sharing transfer method provided by the invention, realized that in medium are shared transmission course the transmission of sharing content is from the new shared recipient of transferring to of current shared recipient, and do not interrupted current shared procedure.By above-mentioned mechanism, can conveniently medium be shared and transfer to pc client, so that media content is stored or further handled from mobile phone terminal; And when current shared terminal power shortage, also can pass through medium sharing transfer method, transfer on the other-end, and do not interrupt current shared transmission.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Description of drawings
Fig. 1 is that the medium of prior art are shared signaling process figure;
Fig. 2 is the flow chart of medium sharing transfer method of the present invention;
Fig. 3 is the signaling process figure of medium sharing transfer method embodiment one of the present invention.
Embodiment
Medium sharing transfer method of the present invention, share in the transmission course at medium, by the transmission terminal of medium shared resource, the receiving terminal of medium shared resource and the Signalling exchange that medium are shared the purpose terminal room that shifts, set up new media transmission channel, and current media stream switched on the new media transmission channel, transmit to new receiving terminal, and do not need to interrupt current shared transmission course.
Referring to Fig. 2, it is the flow chart of medium sharing transfer method of the present invention, comprises the steps:
Step 1, in medium are shared transmission course, the current receiving terminal of medium shared resource sends shared redirect request message to the transmission terminal of medium shared resource, comprises identification information or the address information of sharing the target terminal that shifts in this shared redirect request at least;
Step 2, described transmission terminal send to described current receiving terminal shares transfer response message;
Step 3, described transmission terminal and described purpose terminal are carried out media negotiation, and set up media channel; This step can adopt existing medium to share flow process and set up media channel, can be specially:
Step 31, described transmission terminal and described purpose terminal room carry out terminal capability exchange;
Step 32, described transmission terminal send to described purpose terminal shares initial request messages;
After step 33, described purpose terminal are received this shared initial request messages, judge whether to agree to share the request of initiation, if the purpose terminal is agreed to share the request of initiation, then send to share and initiate response message to described transmission terminal, execution in step 34 then, otherwise send the shared refuse information of initiating to described transmission terminal, finish;
The media channel of step 34, the foundation of described transmission terminal and described purpose terminal.
Step 4, described transmission terminal are to described purpose terminal transmission medium shared resource.
Can also comprise between described step 3 and step 4: described transmission terminal sends BYE message to described current receiving terminal.
