Problems solved by technology

If the LTE network signal of this channel is poor, it is difficult to guarantee the quality of the call, and it is prone to audio interruption or video freeze
[0007] Therefore, the reliability and stability of existing mobile terminal video calls are relatively poor, and the call quality is not high

example 1

[0249] Such as Figure 11 As shown, the first mobile terminal respectively establishes an IMS channel through the first LTE network and the second LTE network, and the second mobile terminal also establishes an IMS channel through the first LTE network and the second LTE network respectively. When the relay server receives the call data transmitted by the IMS channel of the first mobile terminal, it analyzes and obtains that the channel type of the destination address in the call data is IMS type, and forwards the call data to the second mobile terminal through the IMS channel of the second mobile terminal. Conversely, the processing method of the transfer server receiving the call data of the second mobile terminal is also the same.

[0250] Since the call data is transmitted through two channels, after the first mobile terminal (and the second mobile terminal) receive the call data through different channels, the application processing module calls the encapsulated protocol ...

example 2

[0253] Such as Figure 12 As shown, the first mobile terminal establishes two IMS channels through the first LTE network and the second LTE network, and the second mobile terminal establishes one IMS channel through the LTE network.

[0254] When the relay server receives the call data transmitted by the two IMS channels of the first mobile terminal, the channel type of the destination address in the call data is analyzed to be the IMS type, and the call data is forwarded to the second mobile terminal through the IMS channel of the second mobile terminal. mobile terminal.

[0255] When the relay server receives the call data transmitted by the IMS channel of the second mobile terminal, it analyzes and obtains that the channel type of the destination address in the call data is an IMS type, and forwards the call data to the corresponding IMS channel of the first mobile terminal according to the destination address. A first mobile terminal. Since the call data is transmitted thr...

example 3

[0258] Such as Figure 13 As shown, the first mobile terminal establishes two IMS channels through the first LTE network and the second LTE network, and the second mobile terminal establishes an internet channel through the WIFI network.

[0259] In this embodiment, the channel type includes an IMS channel and an internet channel. When the type of the call data is inconsistent with the channel type of the destination address of the call data, the transfer server performs data conversion on the call data, and converts the type of the call data to match the channel type of the destination address of the call data. The channel type of the address is consistent.

[0260] When the relay server receives the call data transmitted by the IMS channel of the first mobile terminal, it analyzes and obtains the channel type of the destination address in the call data as the internet type, converts the call data into the call data of the internet type, and passes the call data through The ...

Abstract

The invention discloses a video call system, device and method. The method comprises the steps: connecting a first LTE network, and building a first communication channel; building video call connection with an opposite side through the first LTE network, and transmitting call data through the first communication channel; connecting the second LTE network in a video call process when the preset condition is met, and building a second communication channel; and transmitting the call data through the first communication channel and the second communication channel. The beneficial effects of the invention are that the method starts two 4G networks in the video call process for transmitting the call data at the same time, thereby enlarging the network bandwidth, improving the data transmission rate, and improving the video communication quality. Even if the first 4G network signal is weaker, the second 4G network can be used for guaranteeing the video call quality, thereby improving the flexibility of video call and the intelligentization level of a mobile terminal, and improving the video call experience of a user.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a video call system, device and method. Background technique [0002] With the rapid development of communication technology, the mobile communication network has developed from 2G network to 3G network to the current 4G network, and the corresponding data transmission rate is getting faster and faster. Starting from 3G network, video calls can already be supported. [0003] In the current 4G network, the LTE network has been widely used, and it is currently the fastest mobile communication network. Mobile terminals can use the LTE network for VOLTE video calls. VOLTE is VoiceOverLTE, which is an IP data transmission technology that can realize the unification of data and voice services under the same network. In the existing VOLTE video call, the two parties in the conversation pass the image to the other party through the camera function of the mobile te...
