Problems solved by technology

[0005] Although the video call service implemented in the GSM CS domain can be carried at a bandwidth of about 12Kbps after reducing the video stream rate, due to the low bandwidth, the video effect is not good, and the QoS (Quality of Service, quality of service) is poor

Embodiment Construction

[0033] The receiver mobile station in the embodiment of the present invention may be provided with at least two SIM (Subscriber Identity Module, subscriber identification) cards to provide two channels of radio frequency signals. The sender's mobile station establishes a signaling connection with the receiver's mobile station, and establishes at least two data channels with the receiver's mobile station (different data channels are established for different SIM cards of the receiver's mobile station, for example, the receiver's mobile station has two card, then establish two data channels), and corresponding to the number of data channels, divide the video call service data flow into at least two parts, carry them respectively on the at least two established data channels, and send them to the receiving mobile station . The receiver mobile station receives the divided video call service data streams, combines the video call service data streams, and displays them to the user. ...

Abstract

Embodiments of the present invention disclose a method, device and system for implementing a video call service. The method includes: receiving a video call service data stream, where the video call service data stream is respectively carried in at least two data streams connected to a sender mobile station on the channel; combine the video call service data streams to implement the video call service corresponding to the video call service data streams. In the embodiment of the present invention, the video call service data stream is carried on at least two data channels for transmission, which expands the bandwidth of the bearer channel and improves the quality of the video call service.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and system for implementing a video call service. Background technique [0002] At present, the service in the mobile network is mainly the voice call service. With the development of science and technology and the improvement of living standards, people put forward the requirement of video call on the mobile network. Because video calls have high requirements on bandwidth, they can only be carried on mobile networks with relatively high speeds. Therefore, due to bandwidth limitations, traditional mobile networks cannot carry video call services. [0003] In the prior art, by reducing the rate of the video stream, the video call data can be converted into a low-bandwidth GSM (Global System for Mobile communications, Global System for Mobile Communications) CS (Circuit Switching, Circuit Switching) domain. Video call data and sent via GSM CS channel...
