Problems solved by technology

[0004] However, the current VOLTE video call can only be made in the area covered by the LTE network; since the video call needs to transmit voice and image at the same time, the signal strength of the LTE network needs to meet certain requirements
If the LTE network signal in the area is poor, it is difficult to guarantee the quality of the call, and it is prone to broken sound or video freeze
Usually, when the call quality deteriorates or is disconnected, the LTE network itself cannot be improved, and one or both parties of the call can only move to an area with a good LTE signal
[0005] Therefore, the reliability and stability of existing mobile terminal video calls are relatively poor, and the call quality is not high

[0108] Such as image 3 As shown, the first embodiment of the video call method of the present invention is proposed, and the method is applied to a mobile terminal, including the following steps:

[0109] S11. Connect to a mobile communication network, and establish a first communication channel.

[0110] In the embodiment of the present invention, the mobile communication network refers to a communication network based on a SIM card. Currently, mobile communication networks that can support video calls include 3G networks and 4G networks. Among them, 3G networks such as CDMA2000, WCDMA, TD-SCDMA, WiMAX, etc., 4G networks such as LTE, etc. The type of the first communication channel is preferably an IMS (IP Multimedia Subsystem, IP Multimedia System) channel, and of course other types of channels may also be established as required.

[0111] S12. Establish a video call connection with the opposite end through the mobile communication network, and transmit call data through ...

example 1

[0193] Such as Figure 11 As shown, the first mobile terminal respectively establishes the IMS channel and the internet channel through the LTE network and the WIFI network, and the second mobile terminal also establishes the IMS channel and the internet channel respectively through the LTE network and the WIFI network. When the transfer 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 IMS type, and forwards the call data to the second mobile terminal through the IMS channel of the second mobile terminal; When the relay server receives the call data transmitted by the internet channel of the first mobile terminal, it analyzes and obtains that the channel type of the destination address in the call data is internet type, and forwards the call data to the second mobile terminal through the internet channel of the second mobile terminal. Conversely...

[0195] Such as Figure 12 As shown, the first mobile terminal establishes an IMS channel through the LTE network and the WIFI network respectively, and the second mobile terminal establishes an IMS channel through the LTE network.

[0196] 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.

[0197] 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.

Abstract

The invention discloses a video call system, device and method. The system comprises a first mobile terminal, a second mobile terminal and a transfer server, wherein the first mobile terminal is used for establishing a video call connection with the second mobile terminal, establishing a first communication channel and a second communication channel through a mobile communication network and a wireless network, and transmitting call data through the first communication channel and the second communication channel; the second mobile terminal is used for establishing the first communication channel or / and the second communication channel through the mobile communication network or / and the wireless network, and transmitting the call data through the first communication call or / and the second communication channel; and the transfer server is used for receiving the call data, resolving a channel type of a destination address in the call data, judging whether to perform data conversion on the call data or not according to the channel type, and transferring the call data through a corresponding communication channel. The call data is transmitted through the mobile communication network and the wireless network in a video call process, so that a network bandwidth is extended; the data transmission rate is increased; and the video call quality is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular 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 terminal an...
