Embodiment bis-
Please refer to Fig. 3, it shows the method flow diagram of the data processing method that the embodiment of the present invention two provides, and this data processing method can be applied in any scene of data being carried out to segmentation.The embodiment of the present invention is applied to taking this data processing method in the AM entity of rlc layer as example describes, pending data block can be specially the PDU to be retransmitted retransmitting in buffer memory, data segment can be specially SDU or SDU section, and SDU section is that SDU is carried out to the subdata section after segmentation.This data processing method, comprising:
Step 302: receive corresponding to the re-transmission instruction of this retransmission processes and send resource instruction, obtaining to retransmit and treat that data retransmission is as pending data block in buffer memory according to retransmitting instruction, obtaining treated length according to sending resource instruction;
Retransmitting instruction is at least one pending data block reception mistake of receiving terminal feedback, the instruction that need to resend.In the time that re-transmission is designated as the re-transmission instruction in the AM entity of rlc layer, can be specially PDU status report.In this PDU status report, can include sequence number SN, AM entity can find according to SN the PDU of this SN mark in re-transmission buffer memory, and this PDU is retransmitted.
Sending resource instruction is the instruction of current time processing resource allocation, allows the data length of processing corresponding to current time.In the time sending resource and be designated as the transmission resource instruction in the AM entity of rlc layer, process resource and can be specially channel resource.The present embodiment does not limit to receive and retransmits instruction and the sequencing that sends resource instruction.
Step 304: whether Check processing length is less than the data length of pending data block;
Wherein, the method of obtaining the data length of pending data block has a variety of, for example, can directly read the data length of pending data block, or, the length of header in the total length of known pending data block and pending data block, the length that total length is deducted to header can obtain data length in pending data block etc., and the present embodiment is not construed as limiting the data length that obtains pending data block.
The present embodiment describes as an example of the data length that calculates PDU to be retransmitted example, the length of header in the total length of the known PDU to be retransmitted of AM entity and PDU to be retransmitted, the length that total length is deducted to header can obtain the data length of data in PDU to be retransmitted, and detects according to the treated length of obtaining the data length whether this treated length is less than PDU to be retransmitted.
Step 306: treated length is less than the data length of pending data block if detect, continue to detect whether first data segment in pending data block is divided data section, if detect, in pending data segment, first data segment is divided data section, performs step 308; If detect, first data segment is entire data section, performs step 314;
Owing to only comprising entire data section in current process segments of data or only comprising a divided data section, if detect, first data segment of pending data block is divided data section, only need to carry out segmentation or re-transmission to this divided data section.
Further, can in the header of pending data block, identification information be set, whether to identify first data segment as divided data section.Particularly, describe as example so that identification information to be set in the header of PDU to be retransmitted, AM entity identifies in this PDU to be retransmitted whether comprise SDU section by be arranged to frame information FI in header.Particularly, can FI being set to 00 identifies and in PDU to be retransmitted, does not comprise SDU section, FI is set to 01 and identifies and in this PDU to be retransmitted, comprise a SDU section and last data segment is SDU section, FI is set to 10 and identifies and in this PDU to be retransmitted, comprise a SDU section and first data segment is SDU section, FI is set to 11 and identifies that this PDU to be retransmitted comprises two SDU sections and first is SDU section etc. with last data segment, and the present embodiment is not treated the identification means that retransmits SDU section in PDU and is construed as limiting.
Based on the identification means of SDU section in PDU above-mentioned to be retransmitted, if AM entity detection is 10 or 11 to the FI in header, determine that first data segment is SDU section, execution step 308; If AM entity detection is 00 or 01 to the FI in header, determine that first data segment is SDU, execution step 314.
Step 308: continue Check processing length and whether be greater than the length of first data segment, treated length is not more than the length of first data segment, performs step 310 if detect; If detect, treated length is greater than the length of first data segment, performs step 312;
Wherein, if detect, treated length is not more than the length of first data segment, only need read the data in first data segment; If detect, treated length is greater than the length of first data segment, needs the data in the data segment after first data segment and first data segment to read.
Further, can also calculate according to pending data block the length of first data segment.Particularly, describe as example to calculate first data segment according to PDU to be retransmitted, if only comprise a data segment in PDU to be retransmitted, the total length of PDU to be retransmitted can be deducted to the length of header in PDU to be retransmitted, obtain the length of first data segment; If comprise at least two data segments in PDU to be retransmitted, can obtain by first Length Indication LI in the header of PDU to be retransmitted the length of first data segment.Wherein, a LI is corresponding to a data segment, and last data segment does not have corresponding LI.
Step 310: read out the data that length is treated length in first data segment, data are write to current process data block, flow process finishes.
Because treated length is not more than the length of first data segment, therefore, can directly in first data segment, read out the data that length is treated length.Particularly, describe as an example of SDU section example, if AM entity detection is not more than the length of this SDU section to treated length, in this SDU section, reads the data that length is treated length, and the data that read are write to current PDU section, flow process finishes.
Step 312: the data of first data segment are write to current process data block, and data stuffing is carried out in the remaining data position in current process data block, flow process finishes.
Because treated length is greater than the length of first data segment, therefore, can directly read the data of first data segment.Particularly, describe as an example of SDU section example, if AM entity detection is greater than the length of this SDU section to treated length, AM entity is determined the data of this transmission SDU section, and the remaining data position in current PDU section is filled, to meet the form of current PDU section, flow process finishes.
Step 314: read out the data that length is treated length in pending data block, data are write to current process data block;
Because first data segment is entire data section, therefore, can directly read the data that length is treated length.Particularly, describe as an example of SDU example, if AM entity detection is SDU to first data segment in PDU to be retransmitted, in this PDU to be retransmitted, reads the data that length is treated length, and the data that read are write to current PDU section.
Step 316: whether detect last data segment in data is divided data section; If detect, in data, last data segment is divided data section, abandons last data segment, and data stuffing is carried out in the remaining data position in current process data block.
Owing to only comprising entire data section in current process data block, only comprise SDU taking current PDU section and describe as example, whether after data are write current PDU section by step 314, also needing to detect last data segment in the data that read is SDU section; If detect, last data segment is SDU section, abandons this SDU section, and data stuffing is carried out in the remaining data position in current PDU, and to meet the form of PDU section, flow process finishes; If detect, last data segment is SDU, and flow process finishes.
It should be added that, after reading out current process data block according to treated length in pending data block, can also comprise:
If only comprise entire data section in current process data block, the first mark is set in the header of current process data block, the first mark is used for identifying current process data block and only comprises entire data piece;

Further, in order to simplify the computational process of the header of receiving terminal to current process data block, the first mark and the second mark can also be set in current process data block, this first mark is used for identifying and in current process data block, only comprises entire data section, and the second mark is used for identifying and in current process data block, only comprises a divided data section.
Particularly, describe as current PDU as example taking current process data block, if only comprise SDU in current PDU section, the FI in can the header of current PDU section is set to 00, so that receiving terminal is judged in current PDU section and only comprised SDU according to this FI;
If only comprise a SDU section in current PDU section, the FI in can the header of current PDU section is set to 10 or 11, so that receiving terminal is judged and only comprised a SDU section in current PDU section according to this FI.In addition, owing to only comprising a SDU section in current PDU section, in the header of this current PDU section, LI is not set, can further simplifies the computational process of header.
