Problems solved by technology

[0017] However, the delay jitter of VoLTE voice packets is not only affected by the wireless environment, but also affected by many factors such as equipment anti-interference performance, network retransmission, core network processing delay changes, and network routing changes. It is impossible to accurately predict the delay jitter of VoLTE voice packets, resulting in a relatively low accuracy of the calculated buffer length

Abstract

The embodiment of the invention provides a cache length adjusting method and device, electronic equipment and a storage medium. The method comprises the steps of acquiring delay jitter according to the arrival time of each voice packet in a previous period, wherein the delay jitter comprises a plurality of delays; determining a suggested cache length according to the maximum time delay in the timedelay jitter; and adjusting the length of the cache in the current period according to the suggested cache length. According to the method, the accurate time delay is obtained through the arrival time of the voice packet in the previous period, and the suggested cache length can be accurately calculated, so that the cache length of the current period is adaptively adjusted, the time delay jitteris eliminated, and the voice quality is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, in particular to a method, device, electronic device and storage medium for adjusting a cache length. Background technique [0002] VoLTE (Voice Over LTE, voice service based on LTE network) is a way for 4G (4rd-Generation, fourth-generation mobile communication technology) to carry voice, and it is also the most deployed LTE (Long Term Evolution, long-term evolution) network operator The commonly used voice service method. [0003] Usually, the voice quality of VoLTE is evaluated by MOS (Mean Opinion Score, the average opinion value of voice quality), and MOS is an important indicator for measuring the language quality of a communication system. [0004] The higher the MOS score, the better the voice quality. Generally speaking, if the MOS value is around 4, it means that the call quality is good, and if it is lower than 3, it means that the call quality is rel...
