FIELD: physics, communications.
SUBSTANCE: invention relates to mobile communication. The invention discloses a method and an apparatus for adjusting the speech encoding rate, the method comprising steps of: determining the type of algorithm used by third generation (3G) mobile communication user equipment; if the type of algorithm of the third generation (3G) mobile communication user equipment is Universal Mobile Telecommunications System Adaptive Multi-Rate 2, mapping the rate, corresponding to the codec mode requested by the codec mode request, into a rate control message and transmitting the rate control message to the core network, or, if the algorithm type is Universal Mobile Telecommunications System Adaptive Multi-Rate 1, limiting said codec rate to the lowest rate and mapping into a rate control message for transmission to the core network.
EFFECT: improving compatibility of AMR adjustments between a 2G system and a 3G system and improving speech quality.
