According to the media negotiating process of prior art, video calling both terminal it is not intended that network condition, but directly
The video capability list of oneself is sent to other side, it can include for example being issued to 1280 × 720 resolution ratio in progressive scan
Display format（720p）, Video Graphics Array（Video Graphics Array, VGA）, conventional video standard form
（Common Intermediate Format, CIF）, then video calling both sides are last will to consult to be using this video of 720p
Parameter is that highest-capacity carries out video communication.And if considering network condition, if wherein side's network is poor, it sends oneself
Video capability list may be CIF, then the last media negotiation result of video calling both sides may be exactly CIF.
In the embodiment of the present invention, the terminal of the video calling both sides increased network before media consultation process diagnoses stream in advance
Journey, to provide the capabilities list for being more suitable for present network conditions for media negotiation, for example, resolution ratio etc., helps video calling double
Root selects currently to be adapted to the ability of oneself according to own net condition, so as to influence the result of media negotiation so that media negotiation
Result be more suitable for current network conditions, so as to ensure Video service quality.
Fig. 1 is the flow chart of video communication service processing method one embodiment of the present invention.Shown in Fig. 1, the embodiment
Video communication service processing method includes：
110, when calling party end initiates video call business in response to user's request, obtain and react the calling party end sheet
The first network parameter of ground network condition.
120, the corresponding relation between the calling party end network parameter that pre-sets of inquiry and video parameter is obtained and the
The first video parameter that one network parameter matches.
130, calling party end sends in video call request message, the video call request message to callee's terminal and wrapped
Include the first video parameter.
140, callee's terminal response obtains in receiving video call request message and reacts callee's terminal local net
Second network parameter of network condition.
150, the corresponding relation between network parameter and video parameter that callee's terminal inquiry is pre-set is obtained and the
The second video parameter that two network parameters match.
160, callee's terminal is based on the second video parameter and carries out media negotiation with the first video parameter, determines this video
The video parameter of call business returns to media negotiation result as media negotiation result, and to calling party end.
Exemplarily, media negotiation can be carried out using asymmetric negotiation or asymmetric negotiation mode, corresponding selection second is regarded
The video parameter conduct that frequency parameter is supported with the first video parameter or only the second video parameter or the first video parameter are supported
Media negotiation result.
170, calling party end is based on media negotiation result and carries out video call business with callee's terminal, i.e.,：Start to regard
Frequency is conversed.
The video communication service processing method that the above embodiment of the present invention is provided, user dials or answered visual telephone
When, in the call business flow of video communication, increase the pre- diagnostic operation of network before media negotiation, both call sides are obtained first
