A method and system for video calling

Abstract

The invention provides a method and system for making a video call. The method includes the following steps: after a video call is established, a sending end monitors a current network bandwidth according to a preset monitoring cycle T; when the monitored network bandwidth is higher than a preset threshold, the sending end transmits high-definition-bit-rate video data to a receiving end, and the receiving end clears a cache record, re-caches video data with a time duration L and plays the received video data in a real-time manner; and when the monitored network bandwidth is lower than or equal to the preset threshold, the sending end stops transmitting the video data to the receiving end, and the receiving end repeatedly plays video data with a time duration L, which is cached in a previous monitoring cycle. Through application of the method and the system, an excellent video call experience of a user can be effectively guaranteed and occupancy of network resources is saved.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a method and system for making a video call. Background technique [0002] At present, with the rapid development of mobile communication technologies, more and more mobile terminals have the function of providing video call services to users. However, since the video call service has high requirements on network bandwidth and occupies a large amount of mobile communication network resources, when many users use the video call service at the same time, when the data transmitted in the communication network is large, the video call will be affected. The quality of service transmission, for example, there will be delays in video transmission, mosaics in some images, out-of-sync voice and video, etc., resulting in a decline in user experience. [0003] In order to solve the above problems, some technical solutions are proposed in the prior art to reduce t...

Problems solved by technology

[0004] In the above two existing technologies, still images are used instead of real-time video images, so it is inevitable that the user cannot be given a real video call experience, thereby reducing the user experience.

In addition, because the solutions in the prior art require the user to perform specific function settings through manual operation, and then the video call can be converted into a still image call to achieve the purpose of reducing the occupation of network resources, so the operation method is mechanical and requires the user to perform manual operations. Operation, so the user experience is also poor
