Abstract

本发明公开一种编解码速率的调整方法、装置及媒体网关，其中，编解码速率的调整方法包括：MGW判断第一接口的初始编解码速率与第二接口或者第三接口的初始编解码速率是否一致，其中，第一接口为BSS与MGW之间的A接口，第二接口为MGW与对端MGW之间的Nb接口，第三接口为RNS与MGW之间的Iu接口；当第一接口的初始编解码速率与第二接口或者第三接口的初始编解码速率不一致时，MGW将第二接口或者第三接口的初始编解码速率调整为第一接口的初始编解码速率。通过MGW调整Iu接口或Nb接口与A接口初始编解码速率一致，实现快捷的调整编解码速率，提升语音业务质量，避免在发现语音业务质量差后发起降速率请求的过程较慢，导致编解码速率的调整不及时。
