Method for reducing time delay in links of media interface and base station

Abstract

The invention discloses a method for reducing the time delay in links of a media interface. The method comprises the following steps: taking the frame offset acquired by offsetting frames pre-numbered by the frame offset of a service channel as the sending offset corresponding to the service channel; demodulating service frames from radio-frequency signals by the service channel; and sending the demodulated service frames by a base station when the sending offset is polled. The invention also discloses a base station for reducing the time delay in links of a media interface. The system comprises a configuration module, a timing module, a calculation module and a sending module. By using the method and the base station, the operating complexity for reducing the time delay in links of a media interface can be reduced.

Description

technical field [0001] The invention relates to a service channel time delay technology in wireless communication, in particular to a method and a base station for reducing the time delay of a media plane link. Background technique [0002] In the code division multiple access (CDMA, Code Division Multiple Access) system, the media plane link delay is relatively large, which often leads to the phenomenon of grabbing the call during the call. The specific performance is: A is talking, but due to the long media plane delay, A says B can hear the words after a long time interval, and within this time interval, B will think that A has finished speaking, and B will start to speak, which will affect the user's call quality. It can be seen that to eliminate the above-mentioned call snatching phenomenon, it is necessary to reduce the link delay of the media plane. The media plane link includes: the air service frame transmission link from the mobile station to the base station and ...

Problems solved by technology

[0004] From this process, it can be seen that there is an interval of N frame offsets between the demodulation of the service frame and the sending of the service frame by the channel board, and the encoding of the service frame also takes time, so that the service channel delay will occur

At present, most of the methods for reducing the link delay of the media plane are to reduce the link delay of the media plane by shortening the time used for encoding, but the realization of shortening the time used for encoding is relatively complicated
