Embodiment

Basic thought of the present invention is: when carrying out the reception of PCH data, receive the preceding L (0＜L＜N in the N that complete TTI the comprised subframe continuously, and L is an integer) after the PCH data of individual subframe, the PCH data of L subframe receiving are carried out despreading and demodulation, obtain the bit-level data; Afterwards, add N-L subframe, everybody is 0 data entirely, the bit-level data after adding are deciphered and afterwards adaptability paging processing.

Below, be described with reference to the accompanying drawings the processing method in the paging of the present invention and the realization of device by specific embodiment.

Fig. 5 is a paging method schematic flow sheet of the present invention, owing to generally comprise 4 subframes among the previous TTI of order, therefore, in method shown in Figure 5, is described as specific embodiment with the situation that comprises 4 subframes among the complete TTI.As shown in Figure 5, this method comprises:

Step 501～step 504 is identical with step 401～step 404 shown in Figure 4, repeats no more here.

Step 505: after receiving the PCH data of L subframe continuously, when continuing to receive the PCH data of N-L subframe subsequently, PCH data to L subframe receiving are carried out despreading and demodulation, obtain the bit-level data, and after described bit-level data, increase N-L subframe, everybody is 0 data entirely, afterwards, execution in step 506.

After receiving the PCH data of 3 subframes continuously, when continuing to receive the PCH data of the 4th subframe, PCH data to 3 subframes receiving are carried out despreading and demodulation, obtain the bit-level data, and after described bit-level data, increase a subframe, everybody is 0 data entirely, afterwards, execution in step 506.

Wherein, when N was 4, L generally got 3, still, when channel condition was better, L also may get 2, even got 1, that is: 2 subframes or 1 subframe of receiving are carried out despreading, separated to be in harmonious proportion and decipher, judge whether CRC is correct, and carry out follow-up respective handling according to judged result.In actual applications, N depends in the actual application environment that for the setting of a number of sub frames that TTI comprised, L then depends on the value of N, generally speaking, L get more than or equal to During smaller or equal to the integer of N-1, can finish the purpose that the present invention reduces the PCH Data Receiving time preferably.But, do not get rid of L greater than 0, less than

In time, still can reduce under the situation of PCH Data Receiving time in assurance, obtain correct CRC, thereby so that the time of weak point is finished paging.

In addition, in this step, PCH data that also can a subframe of every reception are promptly carried out the despreading and the demodulation of the PCH data of this subframe, need not wait until that the PCH Data Receiving of L subframe just carries out despreading and demodulation after intact.

Step 506: to added N-L subframe, everybody is that bit-level data after 0 the data are deciphered for the first time entirely, and judges according to first decode results whether CRC correct, if correctly, then execution in step 507; Otherwise, execution in step 508.

To added a subframe, everybody is that bit-level data after 0 the data are deciphered for the first time entirely, and judges according to first decode results whether CRC correct, if correctly, then execution in step 507; Otherwise, execution in step 508.

Wherein, for with step 508 in decoded operation distinguish, described decoding in this step is called first decoding, decoding in the step 508 is called secondary decoding, accordingly, the decode results that described first decoding obtains is called first decode results, and the decode results that described secondary decoding obtains is called the secondary decode results.

Wherein, after the bit-level data of 3 subframes, increase a subframe, everybody is that the reason that 0 data are deciphered is entirely: PCH adopts 1/2 convolutional encoding, there is certain coding gain, data in conjunction with preceding 3 subframes, still may correctly recover the data of the 4th subframe, thereby finish paging.So handle, the time that can shift to an earlier date a subframe begins PCH decoding, and then has shortened the paging processing time, has reduced the electric quantity consumption of UE, prolongs standby time.

Wherein, specifically how to carry out described decoding and how to judge that whether CRC is correctly very known in the prior art, repeats no more here.

Step 507:UE judges whether it is beep-page message at self, if, then inserting response, current handling process finishes; Otherwise, changing sleep pattern over to, current handling process finishes.

Step 508: the PCH data to N-L subframe after L the subframe that receives are carried out despreading and demodulation, obtain the bit-level data, carry out secondary decoding again with the bit-level data of the PCH data of the L that receives in the step 505 subframe, afterwards, execution in step 509.

PCH data to the 4th subframe receiving are carried out despreading and demodulation, obtain the bit-level data, carry out secondary decoding again with the bit-level data of the PCH data of 3 subframes that receive in the step 505, afterwards, and execution in step 509.

Step 509: judge according to the secondary decode results whether CRC is correct, if correct, execution in step 507, otherwise, change sleep pattern over to.

Wherein, no matter UE changes sleep pattern in above-mentioned which step, before entering sleep pattern, all need calculate when change normal mode of operation over to from sleep pattern.It is very known in the prior art specifically how to calculate this time, repeats no more here.

Perhaps, paging method shown in Figure 5 can also be in step 505, after receiving the PCH data of 3 subframes, no longer continue to receive the PCH data of the 4th subframe, then by the time CRC is judged as when incorrect, continue the PCH data of 4 subframes of a complete TTI of reception again, carry out the processing afterwards of step 405 shown in Figure 4 and step 405, this mode can be finished the present invention equally.
