Fig. 4 is the method flow diagram of present embodiment, please refer to Fig. 4, and the downlink packet domain data service coding method of present embodiment mainly comprises:
401: the downlink coding of twice downlink coding in the moment that takies as a complete uplink state sign USF receives correct data to be encoded constantly, the another one downlink coding does not constantly receive data to be encoded or during the data to be encoded mistake that receives, obtains the USF in the described correct data to be encoded;
402: use the USF in the described correct data to be encoded that obtain to carry out the USF precoding of described another one downlink coding data to be encoded constantly;
In the present embodiment, twice downlink coding that complete USF takies refers to that constantly the RTTI configuration is lower, when adopting BTTI USF mode, twice coding moment of front and back 10ms that complete USF takies, when in these two moment the data to be encoded that receive being encoded, use identical USF to carry out the USF precoding, thus, therein moment do not receive data to be encoded or the data to be encoded mistake that receives after, can utilize the characteristics identical with another USF that constantly uses, utilize this USF to carry out coding twice, realize the complete coding of USF.

404: a segment data that makes up is encoded, and the back segment data obtains encoding;
405: the data segment data that make up are encoded, and rear data segment data obtain encoding;
In the present embodiment, because in another downlink coding constantly, there are not corresponding data to be encoded, perhaps corresponding data to be encoded mistake, therefore, need to make up data to be encoded, and respectively a segment data and the data segment data of the data to be encoded of this structure are encoded, so that be carved with a complete cataloged procedure during this another downlink coding, namely comprised the USF precoding, head section coding and data segment coding, so that terminal can be according to the USF that constantly obtains in another downlink coding among the USF that constantly obtains of downlink coding and the step 402-405 therein in the step 401, obtain information behind the complete USF coding, finish uplink scheduling.
406: the USF after described coding the, a segment data, data segment data are interweaved, shine upon, and the data after the mapping that will interweave send to portable terminal.
In the present embodiment, the action of step 401-406 can be carried out by the downlink packet domain data service code device, and this downlink packet domain data service code device can be included in the base station.
In the present embodiment, if last downlink coding receives data to be encoded constantly, the data to be encoded mistake that rear one descending coding does not constantly receive data to be encoded or receives, then constantly the data to be encoded that receive are encoded in last downlink coding, and keep USF in these data to be encoded; The USF that constantly directly utilizes last downlink coding constantly to remain at a rear coding carries out the USF precoding, then the segment data and the data segment data that make up is encoded, to realize the complete coding of USF.
In the present embodiment, if the data to be encoded mistake that last downlink coding does not constantly receive data to be encoded or receives, rear one descending coding receives data to be encoded constantly, then according to the damping characteristics of downlink data, USF in the data to be encoded that a descending coding receives constantly after last downlink coding is utilized constantly carries out the USF precoding, then the segment data and the data segment data that make up is encoded; Constantly the data to be encoded that receive are encoded at rear one descending coding, to realize the complete coding of USF.
Wherein, the damping characteristics of downlink data refers to that the descending data to be encoded of receiving are not encoded at once, can receive a few bag downlink datas after, just begin to first the bag downlink data encode.Cushioning 2 bags as example, coding be the 1st bag, but since have buffering in fact the 2nd bag data received that also we also can get parameter wherein, like this, when compiling the 1st bag data, finds wrongly, can get the 2nd USF that wraps data and encode; If for the first time coded data is normal, error in data does not for the second time then need to utilize the characteristic of buffering, only needs to keep primary USF, for the second time coding directly use get final product; If only receive bag data, find that it is the constantly data of correspondence of two downlink coding the second downlink coding constantly, think that then the 1st wraps loss of data, at last coding constantly, those bag data that utilization receives, also namely the 2nd USF that wraps in the data carries out the USF precoding, and the segment data and the data segment data that make up are encoded.
Present embodiment does not receive data to be encoded in the base station, or during the data to be encoded mistake that receives, by using USF and a segment data of structure and the mode of data segment data that keeps, realize the complete coding of USF, so that the subsequent movement terminal can receive complete USF information.But because in this case, the data that the base station issues make up at random, portable terminal does not need these data, therefore, present embodiment is behind the data encoding to structure, also to revise the check digit of the downlink data behind the coding, so that portable terminal decoding is unsuccessful and automatically abandon a segment data and the data segment data that the base station makes up.
For the method that makes present embodiment is more clear understandable, be illustrated below in conjunction with the method for the complete coding schematic diagram of USF under the coding schematic diagram under the RTTI configuration shown in Figure 5 and the packet drop shown in Figure 6 to present embodiment, please refer to Fig. 5, Fig. 6.
Fig. 5 is that the RTTI configuration is lower, schematic diagram data before and after the coding when adopting BTTI USF mode, and as shown in Figure 5, twice coding all used identical USF0 and USF1.The method of the embodiment of the invention is when adopting BTTI USF mode, and under normal circumstances, base station controller can issue the data to be compiled that comprise two identical USF for twice by the Abis mouth to the base station.
Method according to present embodiment, when packet loss or wrong bag appear in downlink data, as long as the base station has correctly received twice any bag in the data to be encoded constantly in twice downlink coding that a complete USF takies, namely with the USF information in this bag, carry out coding twice, realize the complete coding of USF0, USF1, guarantee that portable terminal normally receives USF, carry out smoothly uplink scheduling.

At the first coding constantly, encoding to the data block 61 that receives in the base station, and keeps USF0 and USF1 in this data block 61.Same as the prior art, data block 61 is encoded, need to carry out USF precoding 611 to the USF in this data block 61, segment data Head0 in this data block 61 is carried out head section coding (Head section coding) 612, data segment data Data0 in this data block 61 is carried out data segment coding (Data section coding) 613, then the data after encoding are interweaved and shine upon after issue.
At the second coding constantly, because the contents lost of data block 62, segment data Head1 in this data block 62, data segment data Data1 can't recover, but because the USF of data block 62 is consistent with the USF in the data block 61, therefore, when the second coding constantly finds that data block 62 is lost, the USF0 and the USF1 that then use last coding constantly to keep carry out USF precoding 621, can obtain so the complete rear information of USF coding, but because a segment data Head1 and data segment data Data1 lose, need special processing Head section coding 622 and Data section coding 623, according to the embodiment of the invention, can be by making up a segment data and data segment data, then a segment data that makes up is carried out Head section coding, and the data segment data that make up are carried out the Data section encode to realize, behind the coding, can interweave according to the data of normal flow process after to coding issues after the mapping.
Because a segment data of aforementioned structure and data segment data are to receiving the terminal of these data, such as portable terminal, nonsensical, therefore, harmless to portable terminal for the data that guarantee this structure, also to make amendment to the check digit of the data behind the coding, because the modification of check digit, meeting abandons a segment data and the data segment data of this structure automatically so that portable terminal decoding is unsuccessful, so can reach the purpose harmless to portable terminal.
Embodiment shown in Figure 6 uses the data block 62 of identical USF to lose to be example, use the method for present embodiment, when data block 61 is lost and is received data block 62, damping characteristics according to downlink data, can utilize the USF in the data block 62 and make up data and carry out the coding first time, again data block 62 is carried out the coding second time, then the mapping that interweaves issues, so also can guarantee the complete coding of USF, make receiving terminal, can receive complete USF information such as portable terminal, and then realize uplink scheduling, not repeat them here.
The method of present embodiment is for the characteristic of GSM Abis interface IPization, be that Abis interface is when adopting the IP mode to transmit, disturb owing to exist in the transmission course, and the shake of IP transmission meeting introducing packet, out of order, this can cause packet loss, wrong bag probability to increase, when traffic carrying capacity was larger, the probability of packet loss, wrong bag is fought for and can further be increased to bandwidth, and these are presented as that in service surface re-transmission increases, service feature descends.After using the coding method of present embodiment, can reduce the descending packet loss of packet domain, wrong impact of wrapping ascending performance, promote the ascending performance of block domain data service.In addition, when Abis interface adopted the TDM mode to transmit, clock was unstable, transmission is disturbed and also can be caused data transmission fault, under this scene, adopt the method for present embodiment, can reduce equally the descending packet loss of packet domain, wrong impact of wrapping ascending performance, promote the ascending performance of block domain data service.
