Problems solved by technology

[0004] However, the current bandwidth adaptive speed regulation methods are all passive speed regulation based on feedback. Only after packet loss or delay increase is detected, the adaptive adjustment will be responded to. At this time, the quality of the service has been affected. A greater impact, resulting in poor call effect

Abstract

The embodiment of the invention discloses a coding rate control method. The method comprises the steps that UE receives uplink rate estimation information which is sent by a base station and corresponds to the UE; the UE determines a target coding rate according to the uplink rate estimation information obtained by the base station for the UE; and when the rate deviation of the target coding rate and a current coding rate exceeds a preset range, the UE adjusts a to-be-sent signal according to the target coding rate, so the coding rate of the to-be-sent signal approaches to the target coding rate, wherein the current coding rate is the coding rate of sending the signal to the base station currently by the UE. The embodiment of the invention also provides the UE, the base station and a coding rate control system. According to the method, the system, the UE and the base station, the UE actively adjusts the coding rate according to the uplink rate estimation information fed back by the base station, so the coding rate of the signal is adjusted in real time, the coding rate can adapt to the channel quality change rapidly, the service quality is improved, and the delay is reduced.

Description

technical field [0001] The present application relates to the field of wireless communication, and in particular to a coding rate control method, related device and system. Background technique [0002] Video over Long Term Evolution (ViLTE) is an important measure for operators to develop video services. However, the uplink channel quality of Long Term Evolution (LTE) is affected by factors such as terminal power, adjacent interference, fading, occlusion, mobile Doppler, cell handover, and base station deployment. There is a phenomenon of insufficient uplink bandwidth and large fluctuations. Call quality has a huge impact. [0003] At present, the industry has adopted bandwidth adaptive speed regulation to optimize video call services, please refer to figure 1 , figure 1 It is a schematic diagram of the bandwidth adaptive speed adjustment process in the existing solution. First, User Equipment (UE) A sends a media stream to UE B, and then UE B determines the packet loss ...
