The 4.10th step: the conversation software SC disconnection on the computer C is connected with network N.
9. a kind of mobile phone communication according to claim 1 system; It is characterized in that; Conversation software SC also comprises the layered quantization module, is used for voice data is carried out stratified sampling and layered quantization, obtains quality and the multiple voice data that varies in size; And network quality assessed, select the voice data that sends according to network quality.
10. a kind of mobile phone communication according to claim 9 system; It is characterized in that; Voice data stratified sampling method is: suppose that the audio data samples frequency that receives is F; Original audio data to receiving resamples with the sample frequency of F/2 and F/4 respectively, and the voice data that will obtain after will resampling with the sample frequency of F, F/2 and F/4 is called F level, F/2 level and F/4 level voice data respectively;
Voice data layered quantization method is: suppose that it is N that the voice data that receives quantizes figure place; F level, F/2 level and F/4 level voice data are quantized with the quantization digit of N/2 and N/4 respectively again, and the voice data after will quantizing again with the quantization digit of N, N/2 and N/4 is called voice data F-N, voice data F-N/2, voice data F-N/4, voice data F/2-N, voice data F/2-N/2, voice data F/2-N/4, voice data F/4-N, voice data F/4-N/2, voice data F/4-N/4 respectively; Wherein F-N is called 1 type of data, and F-N/2, F/2-N are called 2 types of data, and F-N/4, F/2-N/2, F/4-N are called 3 types of data; F/2-N/4, F/4-N/2 are called 4 types of data; F/4-N/4 is called 5 types of data;
The concrete grammar of assessment network quality is: network quality is divided into 5 grades; Computer sends to mobile phone with voice data F-N, and the used time of affirmation information that receives mobile phone be T, system preestablishes a time T '; The computational methods of network quality levels are Q=T/T '; Q is positive integer and 1＜=Q＜=5, and Q is big more, and the expression network quality is poor more, and the more little expression network quality of Q is good more;
The voice data method of selecting to transmit according to network quality levels is: when Q=1, select 1 type of data to send, when Q=2, select a kind of transmission the in 2 types of data; When Q=3, select a kind of transmission the in 3 types of data; When Q=4, select a kind of transmission the in 4 types of data; When Q=5, select 5 types of data to send, when every type of data have a plurality of data available, can automatically select a kind of or select wherein a kind of by system by user's own.
