<p>Provided are a method and device for identifying and obtaining AMBE coding and decoding rate information in an SDP. The method for identifying AMBE coding and decoding rate information in an SDP comprises: setting an SDP, and specifically comprises: using a load type PT value to describe AMBE coding and decoding in the m attribute row of the SDP; in the fmtp attribute of the a attribute row of the SDP, identifying a PT value which is the same as that of the m attribute row in a format field, and identifying AMBE coding and decoding rate information in a format specific parameter field; and sending the set SDP to the opposite end. The method and device for identifying and obtaining AMBE coding and decoding rate information in an SDP provided in the present invention can automatically switch the rate of a bearer surface.</p> |
