Voice priority method and system of video phone

Abstract

The invention discloses a voice priority method of a video phone, comprising the following steps of, firstly, before video phoning, setting a mobile terminal to be in a voice priority mode; and secondly, when the communication quality in the process of video phoning is lowered, regulating the encoding number distribution proportion of video / voice data in the current video phone according to the lowering degree of the communication quality, reducing the encoding number of video data in the video phone and increasing the encoding number of voice data. The invention also provides a voice priority system of a video phone. Therefore, the invention ensures the voice communication quality during video phone communication.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a voice priority method and system for a videophone. Background technique [0002] The rapid development of communication technology has brought more convenient communication links to people. Especially the 3G (The third Generation Mobile Telecommunication, third-generation mobile communication network) videophone, which is now under development, not only enables people to hear the voice of the other party during the communication process, but also can see the corresponding video image, Further deepened the relationship between the two parties. [0003] However, the current 3G videophones transmit and play both video and voice data at the same time. When the network is normal, there is no obstacle to the voice call and video image transmission between the two parties. But when the network signal becomes poor or network resources are tight, the quality of video and voice wi...

Problems solved by technology

[0006] The above two patented technologies are based on voice CS (circuit switching, circuit switching domain) and data service PS (packet switching, packet switching domain). In fact, video data is also transmitted in the CS domain in videophones. The existing patented technology cannot Distinguish between voice data and video data because they both belong to the CS domain

Moreover, the above-mentioned existing patented technology checks the priority level of users on the base station side, and provides more resources to high-priority users; if resources on the network side are tight and exceed the limit value, the base station will reduce data services to ensure voice services, that is to say, Differentiating user levels, mobile terminals and users cannot adjust the allocation ratio of voice and video data according to their actual situation

In addition, the above-mentioned patented technologies achieve the purpose of ensuring voice quality by releasing certain network resources (data resources or non-voice resources), but for videophones, once the network resources are released, the call is over

[0007] In summary, there are shortcomings in the videophone communication technology in the prior art, and there are obviously inconveniences and defects in actual use, so it is necessary to improve
