Embodiment one

In order to realize object of the present invention, in the embodiment of the present invention, network side strategic server, for dissimilar terminal applies, determines the transmission policy information of its correspondence.Preferably, during concrete enforcement, strategic server can be, but not limited to according to the requirement of terminal applies to transfer of data real-time, terminal applies is divided into following three types: if when the data transmission delay that terminal applies can be tolerated is no more than the first delay threshold (can be, but not limited to be set to 500ms), determine that this terminal applies is high real-time terminal applies, as the terminal applies of video and game class; If when the data transmission delay that terminal applies can be tolerated is greater than the first delay threshold and is no more than the second delay threshold (can be, but not limited to be set to 800ms), determine that this terminal applies is medium real-time terminal applies, as terminal applies such as PPT or caricature classes; If when the data transmission delay that this terminal applies can be tolerated is greater than the second delay threshold, determines that this terminal applies is low real-time terminal applies, as document class terminal applies, comprise Word document, Excel document or PDF document etc.Accordingly, the transmission policy information that strategic server is determined can be: for high real-time terminal applies and medium real-time terminal applies, strategic server determines that it uses RTP(RTP) carry out transfer of data, and for low real-time terminal applies, determine that it uses HTTP(HTML (Hypertext Markup Language)) or FTP(file transfer protocol (FTP)) carry out transfer of data.For the ease of management, strategic server can distribute an application identities for the terminal applies of each type, such as, determine that application identities corresponding to high real-time terminal applies is 1, determine that application identities corresponding to medium real-time terminal applies is 2, determine that application identities corresponding to low real-time terminal applies is 3, and set up the corresponding relation between application identities and corresponding transmission means, then strategic server can store according to the form of table 1 corresponding relation set up:

Table 1

During concrete enforcement, strategic server can also according to actual conditions, the Data Update in his-and-hers watches 1.

Based on this, embodiments provide the method for transfer of data in a kind of screen locking interaction, as shown in Figure 1, can comprise the following steps:

S101, sending ending equipment, when receiving multi-screen interactive request, according to the transmission policy information obtained from strategic server, determine the data transfer mode corresponding to terminal applies self loaded.

Wherein, the identification information of each receiving device carrying out multi-screen interactive with sending ending equipment is carried in multi-screen interactive request.

The receiving device that S102, sending ending equipment are corresponding with each identification information respectively connects, and according to the data transfer mode determined to each receiving device transmission data.

In the above-mentioned flow process that the invention process provides, in step S101, sending ending equipment is when obtaining transmission policy information, can adopt the mode obtained in advance, namely at sending ending equipment before reception multi-screen interactive request, obtain from the strategic server of network side; Also can adopt the mode of Real-time Obtaining, namely after sending ending equipment receives multi-screen interactive request, obtain from the strategic server of network side in real time.In these two kinds of obtain manners, obtain the mode of mode relative to Real-time Obtaining transmission policy information of transmission policy information in advance, the wait time delay that sending ending equipment and receiving device carry out multi-screen interactive can be reduced.

Particularly, sending ending equipment obtains the process of transmission policy information in advance from the strategic server of network side, as shown in Figure 2, comprises the steps:

S201, sending ending equipment send the subscribe request of subscribing to transmission policy information to strategic server.

After S202, strategic server receive subscribe request, according to this subscribe request, when monitoring the transmission policy self stored and sending change, to sending ending equipment feedback transmission policy information.

S203, sending ending equipment receive and the transmission policy information of storage policy server feedback.

So far, the flow process that sending ending equipment obtains transmission policy information from strategic server terminates.

Based on the transmission policy information obtained, sending ending equipment is when receiving multi-screen interactive request and needing and carry out multi-screen interactive between other terminal equipment, sending ending equipment obtains the application identities corresponding to terminal applies that self loads, concrete, sending ending equipment can call the application identities that multi-screen interactive client-side program interface obtains terminal applies.According to the application identities obtained, from the transmission policy information (corresponding relation namely shown in table 1) obtained, search transmission means corresponding to this application identities.Such as, if the terminal applies of the current loading of sending ending equipment is video file, because video class application refreshing frame per second is very high, it is also high to the requirement of real-time of transfer of data, and therefore it belongs to high real-time terminal applies, and its application identities is 1, known according to table 1, the transmission means of its correspondence carries out transfer of data for adopting Real-time Transport Protocol, concrete, and sending ending equipment can be, but not limited to adopt the mode of RTP OVER UDP to carry out transfer of data.
