Step 13, according to the peak value that related operation is obtained, self-adapting detecting is carried out to adjacent cell.
In specific implementation, after obtaining the peak value that related operation is obtained, neighbour can be carried out using various methods
The self-adapting detecting of cell.
In one embodiment of this invention, the different phase for being detected according to adjacent cell, both can be to described
After the peak value that related operation is obtained carries out adaptive selection, that is, self adaptation is carried out in PSS detection-phases
After detection, then peak value to filtering out carries out non-self-adapting SSS detections, thus shortens adjacent cell in PSS
The detection time of detection-phase；Non-self-adapting sieve can also be carried out in the peak value obtained to the related operation
After choosing, then peak value to filtering out carries out self adaptation SSS detections, it is possible thereby to shorten adjacent cell in SSS
The detection time of detection-phase；Adaptive selection can also be carried out in the peak value obtained to the related operation
Afterwards, the peak value then to filtering out carries out self adaptation SSS detections, it is possible thereby to shorten adjacent cell in PSS and
The detection time of SSS detection-phases.
In specific implementation, carrying out adaptive selection to the peak value that the related operation is obtained can use many
Screening technique is planted, such as, PSS of the whole adjacent area detection process including multichannel can be set and detected, according to
The length of time divides the detection of each round, that is, according to the sequencing of time, is detected by wheel.
The wheel number of specific detection can be set according to actual conditions.Whole adjacent area detection process is divided into some
The PSS detections of wheel, and then can quickly, neatly be obtained by the time span of rationally setting each round
The peak value of SSS detections must be can be used for, detection efficiency is further improved.
Specifically, multiple Preset Time points are pre-set, the PSS of a wheel is performed in each Preset Time point
Detection.The PSS detections of each round can be implemented in accordance with the following steps：Obtained in a certain Preset Time point and wrapped
Data containing PSS, and carry out related calculation；In the peak value that related operation is obtained, by with detected
The interval corresponding peak value shielding of the peak value of different synchronic group cells, and filtered out from unscreened peak value big
In the peak value of corresponding peak threshold, to carry out auxiliary synchronous signals SSS detections.If when the PSS of front-wheel is examined
Survey does not filter out the peak value more than corresponding peak threshold from the peak value not shielded, then hold
The PSS detections of row next round, that is, said process is repeated in next Preset Time point, until at it
In a Preset Time point, filtered out from the peak value not shielded described more than corresponding peak value threshold
The peak value of value.
In specific implementation, the peak value to filtering out carries out self adaptation SSS detections and can also use various inspections
Survey method.Such as, the SSS that can set whole adjacent area detection process including some wheels detects, according to when
Between length divide the detection of each round, that is, according to the sequencing of time, detected by wheel.

Wheel number can be set according to actual conditions.The detection process of asynchronous cell is divided into the SSS of some wheels
Detection, and then can be by the time span of rationally setting each round, quickly, neatly obtaining can be with small
The peak value of area's detection, further improves detection efficiency.
Specifically, multiple Preset Time points are pre-set, the SSS of a wheel is performed in each Preset Time point
Detection.The SSS detections of each round can be implemented in accordance with the following steps：Obtained in a certain Preset Time point and wrapped
Data containing SSS, and carry out related calculation；In the peak value that related operation is obtained, filter out more than correspondence
Peak threshold peak value, as the peak value for cell detection.If when the SSS detections of front-wheel are not screened
Go out the peak value more than corresponding peak threshold, then perform the SSS detections of next round, that is, under
One Preset Time point repeats said process, until a Preset Time point filters out described being more than wherein
The peak value of corresponding peak threshold.
It should be noted that each peak value for filtering out can correspond to multiple cells, it is also possible to only correspond to one
Individual cell.That is, the information of the cell in a synchronic group can be obtained according to a peak value, also may be used
Only to obtain the information of cell in multiple synchronic groups.Wherein, the strong cell of signal can correspond to larger peak
Value, it is also possible to the less peak value of correspondence, and the weak cell of signal generally corresponds to less peak value, therefore,
In the information of the cell in detecting other synchronic groups, can be examined by strong extremely weak order according to signal
Survey, i.e., the cell of the strong synchronic group of first detection signal, further according to the information of the strong synchronic group cell of signal,
The cell of the weak synchronic group of detection signal, it is to avoid during the weak cell of first detection signal, the strong cell of signal
Corresponding less peak value is interfered to detection, and detection efficiency is improved with this, reduces false drop rate.
For example, the cell for having detected includes：Cell 1 in synchronic group A, the cell 2 in synchronic group B
And cell 3, then cell 2 and cell 3 in cell 1, synchronic group B that can be in synchronic group A
Information, the information of the cell 4 in detection synchronic group C.Further according to the cell 1 in synchronic group A, together
The information of the cell 4 in cell 2 and cell 3, synchronic group C in step group B, in detection synchronic group D

Only detect.
It should be noted that in specific implementation, after each synchronic group detects cell, then can examine
Survey other cells in each synchronic group, it is also possible to after the cell in detecting a synchronic group, that is, detect
The information of other cells in the synchronic group.The information for detecting other synchronic group cells, with the detection
Other cell informations in the same synchronic group, can be with parallel processing, it is also possible to serial process, not by suitable
Sequence is limited.
It should be noted that either detecting the information of other synchronic group cells, still detect same
The information of other cells in synchronic group, the cell information that will can detect is put into cell list, with
It is easy to subsequently carry out the operations such as cell switching and gravity treatment.
