METHOD AND DEVICE FOR DECODING SPEECH FRAME

摘要

Disclosed are a method and device for decoding a speech frame. The method comprises: firstly a base station receiving a speech frame sent by a mobile terminal, then decoding the data of the speech frame according to a decoding rate indicated in a decoding rate indication, and when the base station fails to decode the data of the speech frame according to the decoding rate indicated in the decoding rate indication, the base station selecting a decoding rate from a preset rate set to decode the data of the speech frame. In the present invention, when a base station fails to decode the data of a speech frame via a decoding rate indicated in a decoding rate indication, the data of the speech frame is decoded by selecting a correct decoding rate corresponding to the speech frame from a preset rate set, thus improving the decoding performance of the system. The present invention is applicable to the field of communication systems.
