Embodiment Construction

[0062] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0063] In a mobile communication system, terminal equipment can move within the system. When a terminal device moves to a weak coverage area (such as network edge areas, urban areas, shadow areas, fast fading areas, etc.) or an area with high network load (such as an area with a large number of user access), the network signal quality may deteriorate. Gradually reduce, even with the risk of communication interruption.

[0064] In order to maintain continuous communication services, terminal equipment can adjust the encoding mode, encoding rate or error correction code bits to ensure voice quality as the wireless environment changes. Optionally, the terminal device may also trigger event reporting according to signal measurement results of the serving cell and neighboring cells, so as to switch to a...

Abstract

The embodiment of the invention discloses a coding rate adjusting method and related equipment. In the method, terminal equipment can determine a signal strength change rate of a wireless network, and send the signal strength change rate to first access networkequipment. And the terminal equipment receives a first coding rate from the media processing equipment, and the first coding rate is determined according to the signal strength change rate. And the terminal equipment encodes the audio and video data according to the first coding rate. Therefore, the first coding rate can better reflect the current wireless network environment, and the terminal equipment codes the audio and video data according to the first coding rate, so that the packet loss rate is reduced, and the probability of communication interruption of the terminal equipment is reduced.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a coding rate adjustment method and related equipment. Background technique [0002] In a communication system, terminal equipment can adjust the encoding mode, encoding rate, or error correction code bits as the wireless environment changes to ensure voice quality and achieve a balance between data compression and error tolerance. For example, the terminal device may perform adaptive multi-rate (adaptive multi-rate, AMR) coding rate adjustment for speech based on uplink quality, cell load, or uplink signal to interference plus noise powerratio (SINR). [0003] However, when a terminal device enters a weak coverage area (such as network edge area, urban floor area, shadow area, fast fading area, etc.) or an area with high network load (such as an area with a large number of user access), there may be signal attenuation Quick question. For example, for a t...
