The method is properly termed as the feedback method of non-sensitive bit steathily.

Specifically, following is the detailed process of two kinds of feedback methods：

（1）The feedback method of flag bit steathily

Specifically, here with the modulation of gsm system and coded system 1（Modulation and Coding Scheme-1, Abbreviation MCS-1）Exemplified by corresponding service message n, and disappeared by the above-mentioned current business being carried on the time slot of forward traffic channel The detailed process of generation with the mapping of the data block of breath understands that service message n has 4 data blocks, first, will be with service message n phases Corresponding 4 data block number consecutivelies are " 0-3 ".

	0	1	2	3
					PACCH	1,1	1,1	1,1	1,1
MCS-1to MCS-4	0,0	0,1	0,1	1,0
					MCS-5and MCS-6	0,0	0,0	0,0	0,0
MCS-7to MCS-9	1,1	1,0	0,1	1,1

Table 1

The four of data in the flag bit of data block corresponding to the service message that miscellaneous service channel as shown in table 1 is transmitted The combination of group mark 1 and mark 0, for distinguishing different MCS Traffic Channels（MCS Traffic Channels include 9 kinds, and MCS-1 is One of which）And packet associated control channel.Because the present embodiment is by taking MCS-1 Traffic Channels as an example, therefore, MCS-1 is corresponding Mark 1 and mark 0 combination as shown in second group of data in table 1.

It can be seen from table 1, reserved the flag bit of 2 bits in service message n each data block, and with mark 0 and Mark 1 represents the flag bit of this 2 bit, and wherein mark 0 is directed to the odd bits of current data block, and mark 1 is corresponding current The even bit of data block.As shown in Table 1, for transmitting the service message n in MCS-1 Traffic Channels, continuous 4 data There are four kinds of combinations 8 bit flag positions corresponding in block.In theory, mark of the receiving device in 3 data blocks before receiving The service message in different types of MCS Traffic Channels can be recovered to transmit after the information of position and transmission controls in packet with road Channel（Packet Associated Control Channel, abbreviation PACCH）On service message, therefore, transmit in forward direction 2 bit flag positions in the 4th data block in reverse MCS-1 traffic channel data frames corresponding to Traffic Channel can be used for putting Put notification.

Fig. 4 is the timing relationship of gsm system forward traffic channel reverse traffic channel corresponding with the forward traffic channel Figure.As shown in figure 3,1 TDMA frame is made up of continuous 8 time slots, and in different TDMA frames with identical numbering when Gap is used for the different pieces of information block for transmitting same Traffic Channel, and corresponding to forward traffic channel reversely（Defined in the present embodiment Forward traffic channel corresponding to reverse traffic channel be receiving device to sending ending equipment direction channel）In Traffic Channel Data frame compared to forward direction（Forward direction defined in the present embodiment is channel of the sending ending equipment to receiving device direction）Industry The data frame of business channel will early 3 time slots transmission.

Transmission is described in Fig. 5 in forward traffic channel and transmission in reverse traffic corresponding with the forward traffic channel Two data frames in channel.If as shown in figure 4, current number for " 0 " slot transmission be service message n data block, And receiving terminal receives 3 data blocks, i.e., when the 3rd numbering is data block corresponding to the time slot of " 0 ", i.e., service message n is translated Code success, then when reverse traffic channel corresponding to forward traffic channel transmits data, according to being stored in forward traffic channel The service message n position of the 3rd data block find the 4th data block of service message in corresponding reverse traffic channel Position, and change the bit data stored in the flag bit of the 4th data block in above-mentioned reverse traffic channel（I.e. by table 1 's（1,0）It is changed into（0,1）, inform that sending ending equipment does not retransmit will pass through reverse traffic channel corresponding to forward traffic channel Service message n the 4th data block so that the 4th data block for being not required to send service message n of sending ending equipment, complete anti- Feedback process.

Now, sending ending equipment is sent out by obtaining receiving device by reverse traffic channel corresponding to forward traffic channel Data in the flag bit for the data block sent.

Specifically, sending ending equipment receive receiving device transmission by reverse industry corresponding to forward traffic channel After data in the flag bit for the data block that business channel is sent, detect that the data in the flag bit are changed, just stop The remaining data of the current service message is sent to the receiving device.

（2）The feedback method of non-sensitive bit steathily

The method of non-sensitive bit is exactly to place advertisement message in the low data of importance within the data block steathily.Wherein, The non-sensitive bit pre-defines, specifically, can by the generation and mapping process of the data block of above-mentioned service message Know, it is grouped data to transmit the service message in MSC-1 Traffic Channels, and the importance of grouped data will compared to speech data It is weak, thus can be in the transmission in MSC-1 Traffic Channels service message data block in place on the bit position of part and accuse Know information.

Now, sending ending equipment obtains what receiving device was sent by reverse traffic channel corresponding to forward traffic channel Data in the non-sensitive bit of data block.

Specifically, sending ending equipment receive receiving device transmission by reverse industry corresponding to forward traffic channel After data in the non-sensitive bit for the data block that channel sends of being engaged in, detect data in the non-sensitive bit there occurs Change, just stop sending the remaining data of the current service message to the receiving device.

Further, the method for the embodiment of the present invention can also include：If receiving device judges that the service message recovers Mistake, and the number for the data block having been received by is less than the sum of data block corresponding to the service message, then goes to step 304.

304th, receiving device continues to the subsequent data chunk of the current service message.

Also include after the step 304：The data block that receiving device has been received by again through demodulation decoding is recovered The current service message.

Specifically, receiving device judges that the service message recovers mistake, illustrate the data received by receiving device The data volume included in block not enough recovers the service message, therefore, it is necessary to receiving device continues to the service message Subsequent data chunk, and again through all data blocks for having been received by of demodulation decoding, so per one data block of new reception Just the recovery process of a service message is carried out, the chance that can recover service message in advance several times with more offers is set to receiving terminal Standby, for example, when the service message is made up of 4 data blocks, and the preset number is 3, then the service message has 1 time in advance The chance of recovery.Certainly, after receiving device can also all receive data block corresponding to the service message, then basis Partial data block in received data block recovers the service message.

Optionally, after step 302, this method also includes：

305th, when the number for the data block having been received by is equal to the sum of data block corresponding to current business message, receive End equipment terminates the recovery process to current business message.

Specifically, after judging whether current business message recovers correct, no matter whether the current service message recovers Correctly, as long as all data blocks that receiving device is received corresponding to the current service message just terminate to disappear to the current business The recovery process of breath.

The method for the service message transmission that embodiments of the invention provide, by modulating and decoding the data block having been received by Recover current business message, and after the current service message is correctly recovered, notification is sent to sending ending equipment, from And notify that sending ending equipment is not required to send the remaining data of the current service message, is so not required to transmitting terminal by the advertisement message All data blocks of the equipment transmission comprising the current service message just can complete the decoding process to the current service message, The waste of information resources and the power consumption of system and interference can so be reduced.

The embodiments of the invention provide a kind of service message transmission method, and the present embodiment be specifically primarily directed to by The service message of 8 data block compositions, specifically, as shown in fig. 6, this method comprises the following steps：

401st, the preset number for the service message that receiving device receiving end/sending end equipment is sent by forward traffic channel Individual data block.

Wherein, preset number herein is less than the sum of data block corresponding to service message.Therefore, when the service message is When being made up of 8 data blocks, above-mentioned preset number can be 5, it is of course also possible to be any value in 1 to 8, specifically Preset number can be selected in advance by receiving device according to practical situations, then be allocated to sending ending equipment.This Outside, forward traffic channel herein can be in the present embodiment：Sending ending equipment to receiving device direction Traffic Channel, And the reverse traffic channel of the forward traffic channel in contrast can be in the present embodiment：Receiving device is to transmitting terminal The Traffic Channel of device orientation.

Specifically, due to having identical numbering in different TDMA frames（It is by 8 time slot number consecutivelies of each TDMA frame 0-8）Time slot be used to transmit the different pieces of information block of same service message, and sending ending equipment is sending the business by data frame During the data block of message, it is transmitted according to the order of the data block of the service message, therefore, when preset number is 5 When, receiving device received data block is preceding 5 data blocks of the service message.

Optionally, current business message is included in above-mentioned preset number data block in addition to last data block The data of data and previous service message, and last data block and last number in the preset number data block According in the data block after block comprising current business message data and next service message data.Specifically, recovering Before the service message, the data except current business message can be received, it is also possible to the number of next service message can be received According to, it is therefore desirable to the data of the next service message received store, subsequently to recover next service message When use.

Specifically, the generation and mapping of the data block of the current business message being carried on the time slot of forward traffic channel Detailed process is：20ms speech messages have been partitioned into 3 pieces, i.e. the 50 of Ia classes through 260 bit informations caused by speech coder 78 bits of bit, 132 bits of Ib classes and II classes.CRC check of the bit of Ia classes first through 3 bits.Then, I classes bit （Including Ia classes bit and Ib class bits）Together with the tail information of above-mentioned 3 bit CRC and 4 bits respectively by resetting and 1/2 convolution Coding obtains the encoding block of 378 bits.Then, the encoding block has been used together special interior intertexture together with II class bits and adds block to hand over The pattern knitted interweaves to obtain the data block of 456 bits.456 bit datas after interior intertexture are divided into two parts.First Point 228 bit datas it is corresponding before even bit in 4 data blocks, and 228 bit datas of Part II then correspond to after 4 numbers According to the odd bits of block.As can be seen here, any 1 data block has all corresponded to the data of 2 continuous service messages.Finally, for upper The data block for operating 1 generated 156.25 bit is stated, it contains the data of 114 bits, the tail information of 6 bits, 2 bits The midamble code of flag information, 26 bits and the protection interval of 8.25 bits in flag bit.

In addition, EFR Traffic Channel（Traffic Channel/Enhanced Full Speed Rate, referred to as TCH/EFS 244 bit informations and half rate of the service message of transmission in)（Traffic Channel/Half Speed Rate, abbreviation TCH/HS）112 bit informations of the service message of middle transmission, after respectively hang oneself CRC, convolution and intertexture, most There is mutually isostructural data block into TCH/FS throughout one's life.Unlike, TCH/EFS with the addition of one on the basis of TCH/FS Pre-operation, the pre-operation includes plus the CRC and repetition bits of 8 bits；And as above an embodiment is such, TCH/HS only needs 4 Data block carries a service message.

Further alternative, step 401 specifically comprises the following steps：

The data for the service message that 401a, receiving device receiving end/sending end equipment are sent by forward traffic channel Block.

Whether the number of the data block for the service message that 401b, receiving device judge to have been received by is equal to preset number.

If the determination result is YES, then step 401c1 is gone to；If judged result is no, step 401c2 is gone to.

401c1, receiving device start to recover the service message.

401c2, receiving device continue to the subsequent data chunk of the service message until the service message having been received by The number of data block be equal to preset number.

Specifically, in forward traffic channel, receiving device is followed according to above-mentioned steps 301a401a and 401b2 Ring, until the quantity for completing the data block that step 401b2 receiving devices receive reaches preset number, specifically, the implementation Process of the example to the receive process of the data block of the preset number of service message for a cycle criterion.

402nd, the data block that receiving device is had been received by by demodulation decoding recovers current business message.

Optionally, also include after step 402：Receiving device judges whether the service message is extensive according to CRC check It is multiple correct.

After step 402, if the receiving device judges that the service message recovers correct, step 403 is gone to.

403rd, receiving device stops receiving the remaining data of the service message, and by anti-corresponding to forward traffic channel Notification is sent to Traffic Channel to sending ending equipment, the notification is used to notify sending ending equipment to send the business The remaining data of message.

Specifically, step 403, including：

Or

Specifically, in step 403 notification method to set up, it is as implied above to have two kinds of implementation methods.

Wherein, method a1 is by changing in reverse traffic channel corresponding to forward traffic channel, with current business message Remaining data block shared time slot position in forward traffic channel is corresponding, and the data of the odd number flag bit in data block are come in fact Now inform process.

The method is properly termed as the feedback method of flag bit steathily.

Method b1 is by marking in reverse traffic channel corresponding to forward traffic channel, the remainder with current business message According to block, shared time slot position is corresponding in forward traffic channel, and the numerical value of the non-sensitive bit in data block is accused to realize Know process.

（1）The feedback method of flag bit steathily

Specifically, here by taking service message corresponding to the traffic channel full rate TCH/FS of gsm system as an example, and by above-mentioned The detailed process of generation with the mapping of the data block for the service message being carried on the time slot of forward traffic channel is understood, per number The data of two neighboring service message are all carried according to block, here by taking service message n as an example, its adjacent upper service message is N-1, adjacent next service message are n+1.First, it is " 0- by the 8 data block number consecutivelies corresponding with service message n 7 ", with reference to forward traffic channel data frame in service message data block generation and mapping detailed process, numbering is The data block of " 0-3 ", its even bit correspond to service message n data；And number be " 4-7 " data block, its odd bits pair Should be in service message n data.The rest may be inferred, and above-mentioned numbering is the data block of " 0-3 ", and its odd bits disappears corresponding to a upper business Cease n-1 data；And above-mentioned numbering is the data block of " 4-7 ", its even bit corresponds to next service message n+1 data.

Table 2

It can be seen from table 2, the flag bit of 2 bits, the flag bit have been reserved in current business message n each data block Represented with mark 0 and mark 1, wherein mark 0 is directed to the odd bits data of current data block, and the corresponding current data block of mark 1 Even bit data.Therefore be for being stored in numbering " 0-3 " data block in service message n data, mark 1 phase therewith It is corresponding；Be for being stored in numbering " 4-7 " data block in service message n data, mark 0 corresponds.And such as table 2 Two kinds of shown marks 0 and the combination of mark 1, for differentiated service channel and control channel, because the present embodiment is base In Traffic Channel, so in the data block transmitted in the Traffic Channel of the present embodiment（Indicate a, indicate b）Flag bit in Data composition form is（0,0）.

Transmission is described in Fig. 5 in forward traffic channel and transmission in reverse traffic corresponding with the forward traffic channel to believe Two data frames in road.As shown in figure 5, if the slot transmission that numbering is " 0 " is service message n data block, and connecing Receive it is successfully decoded during 5 data blocks, then when by reverse traffic channel transmission data corresponding to forward traffic channel, according to The time slot position of the 5th data block of service message n in forward traffic channel is stored in, is found anti-corresponding to forward traffic channel Corresponding data block into Traffic Channel, and the odd bits in the flag bit of above-mentioned data block are changed to 1 from original 0, To inform that sending ending equipment does not retransmit service message n data so that only wrapped in the follow-up transmitted data block of transmitting terminal Data containing next service message n+1, complete feedback procedure.
