Hereinafter with reference to accompanying drawing, also describe the present invention in detail in conjunction with the embodiments.It should be noted that, in the situation that do not conflict, embodiment and the feature in embodiment in the application can combine mutually.
Fig. 3 is the correcting method flow chart inclined to one side according to the wireless link frame of the embodiment of the present invention, and as shown in Figure 3, the method mainly comprises the following steps (step S302-step S304):
Step S302, when receiving that wireless link increases request, obtain the first downgoing time skew of cell-of-origin wireless link and the second downgoing time skew of Target cell wireless link;
Step S304, judge according to the first downgoing time skew and the second downgoing time skew whether Target cell wireless link and cell-of-origin wireless link are derived from same subscriber equipment (UE), if judgment result is that, be, and, in the situation that it is wrong to determine that the frame of Target cell wireless link exists partially, the Target cell wireless link frame of Target cell wireless link is corrected partially.
In the step S304 of the present embodiment, according to the first downgoing time skew and the second downgoing time skew, judge whether Target cell wireless link and cell-of-origin wireless link can take following mode to carry out from same subscriber equipment (UE):
At first, obtain the second skew difference of the first skew difference, the second downgoing time skew and the Target cell vertical shift of the first downgoing time skew and cell-of-origin vertical shift, obtain again the 3rd skew difference between the first skew difference and the second skew difference, then, continue to judge whether the 3rd skew difference is greater than the threshold value set in advance, if the 3rd skew difference is not more than threshold value, determine that Target cell wireless link and cell-of-origin wireless link are from same UE; If the 3rd skew difference is greater than threshold value, continue to judge whether the difference between the 3rd skew difference and prearranged multiple frame length is greater than threshold value, if the determination result is NO, determine that Target cell wireless link and cell-of-origin wireless link are from same UE, if judgment result is that to be, determine the Target cell wireless link from the cell-of-origin wireless link from different UE.
In the step S304 of the present embodiment, when partially whether frame that to determine the Target cell wireless link exists mistake, can carry out in this way: at first, obtain the 4th skew difference between the first downgoing time skew and the skew of the second downgoing time, judge again whether the 4th skew difference is greater than above-mentioned threshold value, in the situation that the 4th skew difference is greater than above-mentioned threshold value, further determine that there is mistake partially in the frame of described Target cell wireless link.

In the present embodiment, the second downgoing time skew can comprise: the code skew of Target cell vertical shift, Target cell and the descending time delay of Target cell.
As example, to this wireless link frame, inclined to one side correcting method describes in detail the way of below take in practical application:
For example, in actual applications, the inclined to one side correcting method of this wireless link frame can be implemented as follows:
After step 1, NodeB receive that the wireless link of radio network controller transmission increases signaling, calculate difference between the downgoing time skew of the downgoing time skew of Target cell wireless link and cell-of-origin wireless link (the difference here only refer on the occasion of,, no matter it is large which the downgoing time of the skew of the downgoing time of Target cell wireless link and cell-of-origin wireless link is offset, after the two does subtraction, get the absolute value of the two difference), thus judge whether this two wireless links belongs to the signal source that is derived from same UE.
Wherein, in actual applications, the skew of the downgoing time of the cell-of-origin wireless link that NodeB obtains comprises the chip offset (ChipOffset of cell-of-origin wireless link
Source) and the descending time delay (TCell of cell-of-origin
Source), and do not comprise the wireless vertical shift (FrameOffset that connects road in cell-of-origin
Source), that is: the downgoing time skew=ChipOffset of cell-of-origin wireless link
Source+ TCell
SourceThe downgoing time skew of the Target cell wireless link that NodeB obtains comprises the chip offset (ChipOffset of Target cell wireless link
Target) and the descending time delay (TCell of Target cell
Target), and do not comprise the vertical shift (FrameOffset of Target cell wireless link
Target), that is: the downgoing time skew=ChipOffset of Target cell wireless link
Target+ TCell
TargetAfter obtaining above-mentioned information, just can be according to poor (that is: the absolute value of difference between the downgoing time skew of the skew of the downgoing time of cell-of-origin wireless link and Target cell wireless link) of the chip offset of downgoing time calculations of offset UE in the Zhe Liangge community of the skew of the downgoing time of cell-of-origin wireless link and Target cell wireless link thus judge whether two wireless links belong to the signal source that is derived from same UE (in actual computational process, between the downgoing time that need to consider the downgoing time skew of cell-of-origin wireless link and Target cell wireless link is offset, whether having the situation across frame).
If step 2 cell-of-origin wireless link and Target cell wireless link belong to the signal source that is derived from same UE, continue the inclined to one side (FrameOffset of frame of judgement Target cell wireless link
Target) mistake whether, if the mistake of existence, to the frame of Target cell wireless link (FrameOffset partially
Target) corrected.
Certainly, the inclined to one side (FrameOffset of the frame of Target cell wireless link
Target) with the frame of cell-of-origin wireless link (FrameOffset partially
Source) while comparing, if find FrameOffset
TargetAfter improper value, can be by FrameOffset
TargetBe set to a rational value, the scope that the downgoing time skew that makes the Target cell wireless link and the difference of the downgoing time skew of cell-of-origin wireless link can merge at NodeB (is above-mentioned threshold value, this threshold value can be set according to practical situations, and can dynamically adjust) within.
If step 3 cell-of-origin wireless link and Target cell wireless link do not belong to the signal source that is derived from same UE, the signal that the Target cell wireless link is described is revealed and is come by identical scrambler community, belonging to cell scrambling pollutes, be left intact, NodeB will return wireless link to RNC like this increases failure response (message).
It should be noted that, the main improvement of the embodiment of the present invention is when determining that cell-of-origin wireless link and Target cell wireless link are that the frame that is derived from the signal source of same UE and definite Target cell wireless link exists wrong the time partially, carry out the frame deflection correction to the Target cell wireless link in time.And, for the wireless link increment process (being the More Soft Handoff flow process) before or after adjusting, with prior art, be the same.The flow process of carrying out More Soft Handoff after the Target cell wireless link is carried out to the frame deflection correction please refer to Fig. 4 (Fig. 4 is repaired the flow chart of More Soft Handoff success afterwards partially according to the erroneous frame of the embodiment of the present invention), at this, this flow process is no longer repeated.
That is to say, partially and the frame of Target cell wireless link is corrected partially, whole More Soft Handoff just may success for the erroneous frame that can find the Target cell wireless link, and in time the frame of Target cell wireless link being corrected partially is vital step.
