Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the invention, and
It is not all, of embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are without work
The every other embodiment obtained on the premise of going out creative work, belongs to the scope of protection of the invention.
It should be noted that the embodiment and the spy in embodiment in the case where not conflicting, in the present invention
Levy and can be mutually combined.
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, but not as the present invention's
Limit.
In prior art, in HSPA+/LTE communication systems, mobile terminal is sending number to base station side
According to when, generally using hybrid automatic repeat request technology (Hybrid Automatic Repeat reQuest,
HARQ).So-called HARQ technologies, refer to：Mobile terminal sends data, base station side meeting to base station side
Data to receiving carry out the processing procedures such as CRC check, and return to mobile terminal after verification is completed
One feedback message ACK/NACK.If the feedback message that mobile terminal is received is ACK, then it represents that
Base station side successful data reception, mobile terminal can terminate this data transmission procedure；If mobile terminal connects
The NACK during feedback message for receiving, then it represents that base station side receiving data fails, mobile terminal need to start
Data retransmission processes, i.e., resend data to base station side.
In prior art, in mobile terminal side, data transmission procedure is generally included data to be sent according to certain
Sequentially system cache (Buffer) is put into flow process, and data to be sent are read from system cache go forward side by side
Up the two processes of coding of row.Above-mentioned two process is typically separate and carries out according to certain sequential
's.Data to be sent are put into the process of system cache generally to remove along with other data on system bus
Moving past Cheng Yiqi is carried out.If there is removing for the sequential priority data more to be sent of some other data-movings
Move high (moving for data i.e. to be sent runs into larger system bus data jamming), or data to be sent
Move operation because other factors postpone (delay) increase when, it is possible to appear in it is up coding start
When, the operation of moving of data to be sent is not fully complete, then the data in current system cache have
The Legacy Data (legacy data) remained by data is activation operation before possibly, or may be for sky (i.e.
Empty data), such data are thus referred to as invalid datas.If invalid data is sent to base station side,
How data to be sent are merged by the data retransmission operation after no matter in base station side, and which also is difficult to
By CRC check, i.e., whole data transmission procedure is difficult successfully, it could even be possible to therefore triggering many number of times
According to retransmission operation, more system resource is consumed.
In the preferred embodiment of the present invention, based on the above-mentioned problems in the prior art, one is now provided
Plant data is activation inspection method, it is adaptable to mobile terminal.Further, above-mentioned data is activation inspection method
Suitable for the mobile terminal worked based on HSPA+ communication systems, or worked based on LTE communication system
Mobile terminal.
In the preferred embodiment of the present invention, as shown in figure 1, above-mentioned data is activation inspection method is specifically wrapped
Include：
Current data transmission process corresponding data to be sent are sent into mobile terminal by step S1, mobile terminal
System cache in, with complete for current data transmission process transmission prepare operation；
In the preferred embodiment of the present invention, mobile terminal will be associated with the pending of current data transmission process
In sending the system cache of data-moving to mobile terminal, and according to data genaration to be sent during moving
Check code.In other words, mobile terminal will be combined with the data-moving to be sent of check code into system cache.
Then in preferred embodiment of the invention, the data to be sent described in above-mentioned steps S1 include：
The data of current data transmission process are associated with, and according to the check code of these data genarations.
For example, need to send the data of 1000bit in current data transmission process, check code takes 8bit,
Then data to be sent are the data of 1008bit.
In one preferred embodiment of the present invention, addition check code can be carried out before process is moved.
For example need to send the data of 1000bit, check code takes 8bit, then first according to data genaration to be sent
Check code, is subsequently moved together, that is, move the pending of 1008bit and transmit data in system cache.
In another preferred embodiment of the present invention, addition check code can be carried out during moving,
For example need to send the data of 1000bit, check code takes 8bit, then generate accordingly during moving
Check code, finally moves the data of 1000bit, and plus the check code of 8bit, forms treating for 1008bit
Send data.
Step S2, mobile terminal carry out up channel coding to data to be sent, and to be encoded pending
Data are sent to be verified, in verification failure rear steering step S3；
In the preferred embodiment of the present invention, as shown in Fig. 2 above-mentioned steps S2 are specifically included：
Step S21, mobile terminal are verified to data to be sent：
If verification failure, turns to step S3；
Step S22, mobile terminal carry out up channel coding to the data to be sent for passing through verification；
Step S23, mobile terminal by encoded data is activation to be sent to base station side, with backed off after random.
In the preferred embodiment of the present invention, CRC (Cyclic Redundancy can be adopted
Check, CRC) verify the checking procedure carried out in above-mentioned steps S2.
In one preferred embodiment of the present invention, up channel coding can carried out to data to be sent
CRC check is carried out before.Specifically, as described in above-mentioned step S21-S23, first to data to be sent
Carry out CRC check.Due to the presence of invalid data, the number for needing originally to transmit 1008bit may be caused
According to (check codes of the data and 8bit of 1000bit), there was only 500bit data in coding effectively, this
When check code would not be the 8bit for originally generating and preserving check code, therefore CRC schools can be caused
Test failure.In other words, if now CRC check failure, may determine that the number to be sent in system cache
There is invalid data according in.Therefore data to be sent are not carried out with up channel coding, and directly stops working as
Front data transmission procedure.On the contrary, if CRC check success, proceeds current data transmission process,
Data to be sent are encoded, and encoded data to be sent are sent to base station side.
In another preferred embodiment of the present invention, up channel volume can carried out to data to be sent
CRC check is carried out while code.Specifically, in preferred embodiment of the invention, to data to be sent
When carrying out up channel coding, can there be the backup of data to be sent in the system cache, then can be to standby
Part carries out CRC check.If verifying successfully, continue data encoding, and carry out data is activation operation；If
Verification failure, then stop coding, and stop current data transmission process.
Step S3, mobile terminal actively stop current data transmission process, with backed off after random.
In sum, in technical solution of the present invention, CRC is carried out when the up channel for carrying out data is encoded
Verification, and judge whether to need to continue current data transmission process according to the result of CRC check, so as to keep away
There is invalid data in exempting from data to be sent so as to cause data is activation to fail, and follow-up useless data
Retransmission operation, reduces the time delay of data is activation, lifts data transmission efficiency.
