Abstract

The invention provides a multi-channel video call implementing method, a multi-channel video call implementing device and a multi-pass terminal. The method is applied to a multi-pass terminal adoptedas a calling party. The method includes the following steps that: in a process of establishing a video call connection with a plurality of called terminals, the calling party negotiates with each called terminal to determine a resolution, so that a plurality of negotiated resolutions can be obtained; when the negotiated resolutions are not completely the same, the resolution of the lowest level isselected from the plurality of the negotiated resolutions, and the calling party negotiates again with called terminals of which the negotiation results are higher than the resolution of the lowest level, so that the negotiated resolutions obtained after the calling party negotiates with each called terminal can be all resolutions of the lowest level; and the calling party performs video call communication with the called terminals with the resolutions of the lowest level. With the method, device and multi-pass terminal of the invention adopted, the downlink resolutions of the called terminals can be unified, so that the unified display of the interface of the calling terminal can be facilitated.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a method, device and multi-communication terminal for realizing a multi-channel video call. Background technique [0002] The multi-channel video call based on VoLTE (Voice over LTE, LTE network audio and video call) means that the calling terminal creates a multi-channel video call through an IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) PDN (Public Data Network, public data network). Dedicated bearer, making video calls with multiple called terminals at the same time. [0003] In a multi-channel video call, the interface of the calling terminal needs to display images of multiple called users at the same time. Due to the different network conditions of each channel, the assigned QoS (Quality of Service, Quality of Service) is different, and the performance of each mobile phone is different, so that The resolution negotiated between the calling termin...
