Correcting method inclined to the Radio Link frame by taking the way in practical application as an example describes in detail below：
For example, in practical applications, the inclined correcting method of the Radio Link frame can be implemented as follows：
Step 1, NodeB receive radio network controller transmission Radio Link increase signaling after, calculate Target cell without Difference between the downgoing time offset of wired link and the downgoing time offset of cell-of-origin Radio Link（Here difference refers only to On the occasion of, i.e. no matter which the downgoing time offset of Target cell Radio Link and the downgoing time of cell-of-origin Radio Link deviate Greatly, after the two does subtraction, the absolute value of the two difference is taken）, so as to judge whether this two wireless links belongs to from same The signal source of one UE.
Wherein, in practical applications, NodeB obtain cell-of-origin Radio Link downgoing time offset include cell-of-origin without The chip offset of wired link（ChipOffsetsource）With the downlink time delay of cell-of-origin（TCellsource）, without including cell-of-origin The vertical shift of radio link（FrameOffsetsource）, i.e.,：The downgoing time offset of cell-of-origin Radio Link= ChipOffsetsource+TCellsource；It is small that the downgoing time offset for the Target cell Radio Link that NodeB is obtained includes target The chip offset of area's Radio Link（ChipOffsettarget）With the downlink time delay of Target cell（TCelltarget）, without including The vertical shift of Target cell Radio Link（FrameOffsettarget）, i.e.,：The downgoing time offset of Target cell Radio Link= ChipOffsettarget+TCelltarget；After obtaining above- mentioned information, it is possible to according to the downgoing time of cell-of-origin Radio Link The difference of chip offsets of the downgoing time calculations of offset UE of offset and Target cell Radio Link in the two cells（I.e.：Source The absolute value of difference between the downgoing time offset of cell Radio Link and the downgoing time offset of Target cell Radio Link）From And judge whether two wireless links belong to the signal source from same UE（, it is necessary to consider in actual calculating process It whether there is between the downgoing time offset of cell-of-origin Radio Link and the downgoing time offset of Target cell Radio Link across frame Situation）.
If step 2, cell-of-origin Radio Link belong to the signal source from same UE with Target cell Radio Link, after It is continuous to judge that the frame of Target cell Radio Link is inclined（FrameOffsettarget）Whether mistake, it is if there is mistake, then small to target The frame of area's Radio Link is inclined（FrameOffsettarget）Corrected.
Certainly, the frame of Target cell Radio Link is inclined（FrameOffsettarget）It is inclined with the frame of cell-of-origin Radio Link （FrameOffsetsource）When comparing, if finding FrameOffsettargetAfter improper value, then it can incite somebody to action FrameOffsettargetBe arranged to a rational value, make Target cell Radio Link downgoing time deviate with cell-of-origin without The scope that the difference of the downgoing time offset of wired link can merge in NodeB（I.e. above-mentioned threshold value, this threshold value can be according to realities Border applicable cases are set, and can dynamically be adjusted）Within.
If step 3, cell-of-origin Radio Link are not belonging to the signal source from same UE with Target cell Radio Link, Illustrate that the signal of Target cell Radio Link is come by the leakage of identical scrambler cell, belong to cell scrambling pollution, then do not do Any processing, such NodeB will return Radio Link increase failure response to RNC（Message）.
It should be noted that the main improvement of the embodiment of the present invention is when definite cell-of-origin Radio Link and Target cell When Radio Link is derived from the signal source of same UE and determines the frame of Target cell Radio Link partially in the presence of mistake, and When to Target cell Radio Link carry out frame deflection correction.And for the wireless link increment process before or after adjustment（I.e. more Soft handoff procedure）For, it is the same with the prior art.Target cell Radio Link is being carried out to carry out more after frame deflection correction The flow of soft handover please refers to Fig.4（Fig. 4 is that More Soft Handoff is successful after erroneous frame according to embodiments of the present invention is repaired partially Flow chart）, here, no longer repeating the flow.
I.e. it is capable to find that the erroneous frame of Target cell Radio Link is partially and inclined to the frame of Target cell Radio Link Corrected, whole More Soft Handoff is only possible to success, and it is to closing weight to be biased capable correction to the frame of Target cell Radio Link in time The step of wanting.
