Before vertical, selected color displays parameter can be carried in video calling response, more specifically, logical for VoLTE videos
For call business, selected color displays parameter can be carried in SDP answer.
S406. the second mobile terminal is according to the corresponding screen of selected color displays parameter switching.If the second movement is eventually
Selected color displays parameter is held for black and white, then it is to use electronics by currently used screens switch that the second mobile terminal is automatic
Second screen of ink display panel.Certainly, the step of toggle screen need not be immediately performed after color displays parameter is chosen,
Can also simultaneously switch with the first mobile terminal when video calling starts.
S407. server sends the selected color displays parameter of the second mobile terminal to the first mobile terminal.
S408. the first mobile terminal is according to the corresponding screen of the selected color displays parameter switching of the second mobile terminal.
In embodiments of the present invention, the color displays parameter of current screen was sent to for the second movement end by the first mobile terminal
End, and selected color displays parameter is determined by the second mobile terminal, and carried out according to selected color displays parameter
Video calling, black white image is only capable of displaying this avoid a side in video calling both sides, but receives the situation of coloured image, section
The communication resource is saved.The video call method of the present embodiment can be applied before video calling foundation, it is also possible to applied and regarded
In frequency communication process, any one party of video calling can actively initiate the requirement of toggle screen.Certainly, the embodiment of the present invention
Video call method be also not limited to two sides call, more multi-party video calls are also applicable, when in multi-party video calls
Any one party initiates the requirement of toggle screen in mobile terminal, and remaining each side can carry out corresponding screens switch.
Fig. 5 shows the flow of the video call method for dual-screen mobile terminal according to another embodiment of the present invention
Figure, in the present embodiment, by screen characteristics parameter also include ultimate resolution as a example by come describe the embodiment of the present invention for double
Shield the video call method of mobile terminal, so in the case of two ultimate resolution differences of the screen of mobile terminal, depending on
Frequency both call sides detection switch after screen ultimate resolution, then resolution of video call is held consultation, with less than or
Equal to ultimate resolution smaller in the mobile terminal of video calling both sides resolution ratio as resolution of video call, it is to avoid
The ultimate resolution of one mobile terminal is, for example, 720P, but receives the video of such as 1080P resolution ratio, so high-resolution
Video does not have in all senses for the first mobile terminal, right because the ultimate resolution of the first mobile terminal only has 720P
It is a kind of situation of waste for the communication resource, such that it is able to save the communication resource.As shown in figure 5, the method can include：
S501. the color displays parameter of the first acquisition for mobile terminal current screen, particular content is with reference to described in step S401；
S502. the first mobile terminal sends the color displays parameter of current screen to server, and particular content refers to step
Described in S402；
S503. server sends the color displays parameter of the first mobile terminal, particular content reference to the second mobile terminal
Described in step S403；
S504. the second mobile terminal is joined according to the selected color displays of color displays parameter determination of the first mobile terminal
Number, particular content is with reference to described in step S404；
S505. the second mobile terminal sends selected color displays parameter to server, and particular content refers to step
Described in S405；
S506. the second mobile terminal is according to the corresponding screen of selected color displays parameter switching, particular content reference
Described in step S406；
S507. server sends the selected color displays parameter of the second mobile terminal to the first mobile terminal, specific interior
Hold with reference to described in step S407；
S508. the first mobile terminal is according to the corresponding screen of the selected color displays parameter switching of the second mobile terminal,
With reference to described in step S408, in the present embodiment, above step is identical with the embodiment step shown in Fig. 4 for particular content；
S509. the ultimate resolution of the first acquisition for mobile terminal institute toggle screen；
S510. the first mobile terminal sends the ultimate resolution of institute's toggle screen to server；
S511. server sends the ultimate resolution of the screen of the first mobile terminal to the second mobile terminal；
