Embodiment 1

[0052] The embodiment of the present invention provides a data transmission method, the execution subject of the method is the calling client, such as figure 1 As shown, the method includes:

[0053] Step 101, the calling client establishes a communication transmission link with the called client, and the communication transmission link includes: a P2P transmission link and a relay transmission link.

[0054] The calling client is the client that initiates the VOIP call, and the called client is the client that receives the VOIP call.

[0055] In the embodiment of the present invention, P2P means that the two ends of the communication directly perform data transmission, without a transmission link that needs to be transferred by a server. When using a P2P transmission link for audio and video calls, it does not need to occupy server resources and network bandwidth, but it will be affected by the quality of the core network. The relay transmission link refers to the transmiss...

Embodiment 2

[0153] An embodiment of the present invention provides a data transmission device, such as Figure 4 As shown, the device is included in the calling client, and the device includes: a communication transmission link establishment unit 401, a detection unit 402, and a switching unit 403;

[0154] A communication transmission link establishing unit 401, configured to establish a communication transmission link with the called client, and the communication transmission link includes: a point-to-point P2P transmission link and a relay transmission link;

[0155] A detection unit 402, configured to detect the P2P transmission link when the calling client and the called client transmit audio and video data using the P2P transmission link established by the communication transmission link establishment unit and the transmission quality of the relay transmission link;

[0156] The transmission quality includes the packet loss rate of the transmission link or the transmission delay of...

Abstract

The invention discloses a data transmission method, an apparatus and a terminal device, and relates to the technological field of communication network. According to the invention, voice or video call quality can be improved when the transmission quality of the core network is unstable, particularly in the case of inter-operator. A communication transmission link is established a calling client and a called client; the communication transmission link comprises a point-to-point (P2P) transmission link and a relay transmission link; transmission quality of the P2P transmission link and that of the relay transmission link are detected when the calling client and the called client employ the P2P transmission link transmit audio and video data; the audio and video data is transmitted by switching the P2P transmission link to the relay transmission link when the transmission quality gap value between the P2P transmission link and the relay transmission link is bigger than or equal to a first preset threshold. The invention is suitable for switching transmission links.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method, device and terminal equipment. Background technique [0002] When a Voice over Internet Protocol (Voice over Internet Protocol, VOIP) client makes a voice or video call, usually after the client initiates a VOIP call, it uses technologies such as Interactive Connectivity Establishment (ICE) to perform connectivity detection and establish data transmission. The link transmits voice or video data. When establishing a data transmission link, in order to save server bandwidth resources and processing resources, when multiple links are successfully established, a point-to-point (Peer To Peer, P2P) transmission link is usually selected as the data transmission link according to the priority algorithm. The transmission link releases the relay transmission link between the client and the Stun (Simple Traver sal of User Datagram Protocol through...
