Embodiment Construction

[0027] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] figure 1 It is a flowchart of a method for adjusting a code rate of a data packet according to an embodiment of the present invention. like figure 1 As shown, the code rate adjustment method of the packet includes:

[0029] Step S101: the server detects the first packet loss rate of the uplink data packets received from the first client within a predetermined detection period;

[0030] Step S103: When determining that the first packet loss rate is greater than the first predetermined value, the server sends signaling to the first client, wherein the signaling carries information instructing the first client to reduce the code rate for sending uplink data packets;

[0031] Step S105: The server receives the uplink data packet from the first client, and detects the first packet loss rate of the uplink data packet within a predet...

Abstract

The invention discloses a data packet code rate adjustment method and device. The method includes: the server detects the first packet loss rate of the uplink data packet received from the first client within a predetermined detection period; When the first packet loss rate is greater than the first predetermined value, the server sends signaling to the first client, wherein the signaling carries information instructing the first client to reduce the code rate for sending uplink data packets; An uplink data packet of a client, and detect the first packet loss rate of the uplink data packet within a predetermined period, so as to judge whether it is necessary to continue sending the information of reducing the code rate to send the data packet to the first client. According to the technical solution of the present invention, the server can dynamically adjust the bandwidth occupied by the video according to the current packet loss rate, and provide high-definition video as much as possible while ensuring smooth video, so that users can make high-quality video calls.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for adjusting the coding rate of data packets. Background technique [0002] At present, the mobile Internet has become very popular, and the demand for using mobile phones to make video calls has become a very important demand point, and it is also a function that users often use. However, in many cases, when the mobile phone uses the mobile network, it will be used on the move , which will cause network quality instability. [0003] Normally, if the bandwidth occupied by video transmission exceeds the current maximum bandwidth of the mobile phone, the packet loss rate will rise in a straight line. In the case of packet loss, the fluency of the video will be greatly affected. Moreover, on the premise of considering the fluency, the definition of the video must also be considered, because the definition of the video is also an important factor affecting ...
