S12, the first base station send second code rate to the terminal；
S13, the first base station receive the voice data that the terminal uses second code rate to send.
For example: first code rate can be specific rate value, for example, the first code rate is 6.6kbit/s；It may be number of first code rate in the rate set belonging to it, such as, rate set is combined into { 6.6kbit/s, 12.65kbit/s, 23.85kbit/s }, 6.6kbit/s in rate set can be designated by numeral 1, and 12.65kbit/s can be designated by numeral 2, and 23.85kbit/s can be designated by numeral 3；First code rate can be number 1.The specific implementation form of the first code rate is not limited in the embodiment of the present invention.
Optionally, the code rate set can be the second code rate intersection of sets collection of the first code rate set and pre-configuration that the terminal and another terminal communicated with the terminal are negotiated,
For example: assuming that two terminals communicated are terminal A and terminal B, the code rate set itself supported is sent to B terminal by core net by terminal A, the code rate intersection of sets collection that the code rate set itself supported and terminal A are supported is determined as the first code rate set by terminal B, first code rate set is sent to terminal A by core net by terminal B, while the first code rate set is sent to base station by core net；The code rate set is also possible to notify terminal after first base station determines, can also be for defined in agreement or standard.

Under such mode, the base station is by reducing the code rate currently carried out data transmission with the terminal, to adjust the current code rate carried out data transmission with the terminal, i.e., the code rate that adjustment first base station and the terminal carry out data transmission downwards.
Under which, it can continuously set number and judge whether the packet loss of the voice data of the terminal is big
In third thresholding, if it is assumed that continuously the packet loss of the voice data of terminal described in setting number is greater than third thresholding, think that it meets regularization condition, it is assumed that setting number as 2 times, can also determine according to the demand of user, in order to avoid frequently adjusting code rate, after judging that packet loss continuously sets number greater than third thresholding, then when judging the value of transmission block less than four thresholdings, first base station reduces the code rate currently carried out data transmission with the terminal.
In the embodiment of the present invention, when the current encoding rate difference that base station and terminal carry out data transmission, the third thresholding of the packet loss of required satisfaction can be the same or different when carrying out the reduction of speed adjustment of code rate, assuming that needing to meet packet loss greater than 3% when current encoding rate 23.85kbit/s is adjusted to 12.65kbit/s；When current encoding rate 12.65kbit/s is adjusted to 6.6kbit/s, needs to meet packet loss greater than 8%, in the embodiment of the present invention, the value of third thresholding is not construed as limiting.
It illustrates, assuming that the current encoding rate that first base station and the terminal carry out data transmission is 12.65kbit/s, judge that packet loss is greater than third thresholding twice in succession, and when judging the value of transmission block less than four thresholdings, determine that the terminal meets the condition for reducing code rate, the current encoding rate 12.65kbit/s carried out data transmission with the terminal is adjusted to 6.6kbit/s by the first base station；In the embodiment of the present invention, using 2.5s as a cycle, judge that packet loss was greater than on third thresholding i.e. continuous two periods twice in succession and judges that packet loss is greater than third thresholding, wherein, third thresholding can be 8%, 4th thresholding of the value of transmission block is not construed as limiting, when with specific reference to practical operation the case where determines.
