IP bag is passed through BTS by step 407, BSC;
Step 408, BTS receive IP bag from Abis interface;
Step 409, judge IP bag in data whether be the valid frame such as speech frame, mute frame, if so, then perform step 410; Otherwise, perform step 412;
Step 410, BTS send present frame and the valid frame such as speech frame, mute frame carries out chnnel coding and sends to mobile terminal, achieves to be carried down by IP in gsm to pass speech data.
Step 411, TC abandon present frame, no longer transmit present frame in GSM, thus complete the transmission process to down-transmitting data, decrease network load, improve data transfer rate.
Step 412, BTS abandon the data in IP bag, decrease unnecessary network expenditure.
In system embodiment, source encoding and decoding unit can be replaced by the TC module in TRAU or MGW.
Uploading system embodiment
Fig. 7 is the present invention's structural representation to uploading data treatment system embodiment in cordless communication network such as GSM, in the present embodiment, source coding unit is realized by TRAU module, system comprises BTS 11, BSC 12, TRAU 13 and MGW 14, BTS 11 carries out eating dishes without rice or wine data interaction by Um Interface and mobile terminal, in upload procedure, BTS 11 receives from Um Interface data of eating dishes without rice or wine, and carries out channel decoding; Base station discard module 15 is also provided with in BTS 11, when the data received are the valid frames such as speech frame, mute frame, then these valid frames are encapsulated as IP bag and send to TRAU 13 by BTS, otherwise, base station discard module 15 abandons and no longer processes, also not up transmission.TRAU 13 receives IP bag from Abis interface, is provided with decoding discard module 16 in TRAU 13, and when in the IP bag received, data are valid frame, then TRAU 13 sends to MGW 14 after the data in IP bag are carried out source coding; Otherwise decoding discard module 16 abandons invalid frame, and TRAU 13 no longer processes.MGW receives IP and wraps and send to core net.
In the present embodiment, BTS 11 also can comprise mute frame discard module, when the data of eating dishes without rice or wine that BTS receives are EFR, FR or HR business datum, and when the present frame after decoding is mute frame, then BTS arranges rolling counters forward, mute frame discard module abandons other mute frames beyond the mute frame of setting reception, to ensure that mute frame interval sends, thus reduce data to be sent, improve GSM and upload the speed passing data, to meet the demand of EFR, FR or HR business.
When the decoding discard module in the present embodiment replaces with coding discard module, TRAU can be used to the function realizing source coding unit, and the system after replacement just becomes the system processing down-transmitting data in gsm communication network.Now, similarly, in TRAU, also mute frame discard module can be set, to ensure that the speed of down-transmitting data meets the demand of EFR, FR or HR business.
Under pass system embodiment
Fig. 8 is the present invention's structural representation to down-transmitting data treatment system embodiment in gsm communication network, and in the present embodiment, the function of source coding unit is realized by the TC module in MGW.Native system comprises: BTS 21, BSC 22 and MGW 23; BTS 21 also comprises base station discard module 24, and during down-transmitting data, the TC module 25 in MGW 23 receives G.711 form PCM speech data, and carries out corresponding message sink coding process; When the data of output of encoding are valid frames, then the data encapsulation that coding exports is IP bag by TC module 25, sends to BSC 22 by MGW 23, otherwise coding discard module 26 abandons these data, does not do and transmits; The IP received bag is passed through BTS 21 by BSC 22; BTS 21 receives IP bag from Abis interface, when being valid frame in the data received, then BTS 21 carries out chnnel coding to the data received, and valid frame is sent to mobile terminal by Um Interface, otherwise base station discard module 24 abandons these data, BTS 21 does not encode, the process such as biography down, has greatly saved Internet resources, has improve transmission rate.
In the present embodiment, TC also can comprise mute frame discard module, when the PCM data that TC receives are EFR, FR or HR business datum, if and present frame after coding when being mute frame, then TC arranges rolling counters forward, and mute frame discard module abandons other mute frames beyond mute frame that setting receives, to ensure that mute frame interval sends, thus reduce data to be sent, improve the speed of GSM down-transmitting data, to meet the demand of EFR, FR or HR business.
When the coding discard module in the present embodiment replaces with decoding discard module, and when TC realizes the function of source coding unit, the system of the present embodiment just becomes the system processing uploading data in gsm communication network.During uploading data, BTS 21 receives from Um Interface data of eating dishes without rice or wine, carry out channel decoding, when valid frames such as the data that decoding obtains speech frame as well, mute frames, then the data encapsulation after decoding is that IP bag sends to BSC 22 by BTS 21, otherwise base station discard module 24 abandons the data received; IP bag is passed through MGW 23 by BSC 22; TC module 25 in MGW 23 receives the speech data of IP encapsulating dress from Ater mouth; When valid frames such as the speech frame that the data that TC module receives have been, mute frames, then the data received are carried out message sink coding and are sent by MGW23 by TC module 25, otherwise, decoding discard module abandons the data received, MGW 23 does not upload these data yet, now TC module 25 generates level and smooth PCM data, to ensure the continuity of the PCM data being sent to core net.
Similarly, in BTS, also mute frame discard module can be set, to ensure that the speed of uploading data meets the demand of EFR, FR or HR business.
