In the embodiment of the present invention, whether can meet standard deviation condition by judgment criteria difference, judge whether ratio meets ratio
Value condition, and judge the average rate of change whether the first change rate condition, or, the second change rate condition, or, third change rate item
Part, with the corresponding adjustable strategies of determination.Specifically, can be by judging whether the standard deviation is greater than standard deviation threshold method, with judgement
Whether standard deviation meets standard deviation condition, if the standard deviation is greater than standard deviation threshold method, it is determined that the standard deviation meets standard
Poor condition illustrates that the RRC connection in N number of period is created as power relative discrete, then the RRC connection of cell is created as power and very may be used
It can be changed；If standard deviation is less than standard deviation threshold method, it is determined that the standard deviation is unsatisfactory for standard deviation condition, that is, illustrates N
The RRC connection in a period is created as power Relatively centralized, then it is more stable to be created as power for the RRC connection of cell；Wherein, described
Standard deviation threshold method can be arranged as desired.It can be by judging whether the ratio is less than fractional threshold, to judge the ratio

Demand setting such as 1.Can be by judging whether the average rate of change is greater than low threshold, and it is less than high threshold, it is described flat to judge
Whether equal change rate, which meets first, has changed condition, if the average rate of change is greater than low threshold, and is less than high threshold, it is determined that described
The average rate of change meets first and has changed condition, then the RRC connection in M period is created as power in slight deterioration；It can be by sentencing
Whether the average rate of change of breaking is greater than high threshold, if so, determining that the average rate of change meets the second change condition, i.e., M week
The RRC connection of phase is created as power in rise trend；And can by judging whether the average rate of change is less than low threshold, if
It is less than, it is determined that the average rate of change meets third change condition, i.e., the RRC connection in M period is created as power severe exacerbation；Its
In, high threshold and low threshold can be arranged as desired.
If step 205, the standard deviation meet standard deviation condition, ratio meets ratio condition, and the average rate of change meets
First change rate condition is then adjusted according to the first strategy.
If the standard deviation meets standard deviation condition, ratio meets ratio condition, and the average rate of change meets the first variation
Rate condition determines that the RRC connection of cell is created as power and is changed, and M period RRC connection is created as power entirety
It is on a declining curve, and the RRC connection in M period is created as power in slight deterioration；Then determine corresponding strategy for the first strategy.
Wherein, the first strategy includes at least following one kind:
(1) cell for improving the cell selects thresholding.
In the embodiment of the present invention, when UE is in idle mode (be switched on from terminal to RRC connection and establish this period), need
It searches a suitable cell to carry out being resident the network service that could obtain, therefore UE needs to complete cell selection as early as possible.Wherein,
UE can measure the cell selection reception signal strength of cell according to S criterion, to determine the cell if appropriate for resident；It can specifically press
Cell selection reception signal strength is calculated according to following formula:
Srxlev=Qrxlevmeas-(Qrxlevmin+Qrxlevminoffset)-Pcompensation,
Wherein, SrxlevIt is cell selection reception signal strength, QrxlevmeasIt is cell received signal level value, QrxlevminFor
Cell selects thresholding, PcompensationFor max (PEMAX-PUMAX, 0) and (dB), wherein PEMAXIt is terminal when accessing the cell, system
The maximum allowable transmission power of setting；PUMAXRefer to the peak power output according to as defined in terminal grade.QrxlevminoffsetOnly
A VPMN is normally resided in, the periodical PLMN for searching for a high priority carries out ability effective, ginseng when cell selection assessment
Several couples of QrxlevminCarry out certain biasing.
If Srxlev> 0, it is determined that the cell is suitble to be resident, if Srxlev< 0, it is determined that the cell is not suitable for being resident, therefore can
To select thresholding Q by improving cellrxlevmin, reduce the probability and the frequency that user accesses in this cell.
(2) cell reselection priority of the cell is improved.
As the movement and wireless environment of UE becomes improper, and adjacent cell is likely to become that be more suitable for terminal resident
Cell, therefore UE can carry out cell reselection, be resident with searching more suitable cell.According to TS36.304 agreement, for weight
Priority is selected to be higher than the carrier frequency of serving cell, UE can directly measure its cell selection reception signal strength；And it is preferential for gravity treatment
It is strong just to measure its cell selection reception signal when this kind of cell meets R criterion for the carrier frequency that grade is equal to or less than serving cell
Degree.
Wherein, the corresponding calculation formula of R criterion is as follows:
Rs=Qmeas_s+Qhyst, Rn=Qmeas_n-Qoffsets_n
Wherein: Qmeas_sFor serving cell received signal quality measured value, Qmeas_nFor the measurement of adjacent cell received signal quality
Value；Qhyst, it is cell reselection sluggishness Qoffsets_nFor the difference of two cell received signal quality requirements.
If the Rn and Rs that continuously measure interior when detecting can keep Rn > Rs, it is determined that adjacent cell meets R criterion,
Then UE can carry out cell reselection, that is, measure its cell selection reception signal strength.Therefore cell reselection priority is reduced, so that UE
It is easier to carry out cell reselection, is linked into adjacent cell, reduces probability and the frequency that UE is accessed in the cell.
Certainly it can also adjust other cell reselection parameters, reduce probability and the frequency that UE is accessed in the cell.
(3) the forbidden factors A C-barring Factor of cell and the forbidden time AC- of cell of the cell are dynamically adjusted
Barring Time。
UE is initiating to check that cell forbids the information of access when RRC connection, wherein may include AC-barring
Factor.UE understands oneself first takes a value at random, but compares with this AC-barring Factor, if that selects is random
Value is lower than Factor, and cell can access.Otherwise UE thinks that cell is prohibited access.This forbid access time by
AC-Barring Time is determined.Therefore the embodiment of the present invention can reduce connecing for cell by adjusting AC-barring Factor
Enter probability, and increase AC-barring Time, to reduce the frequency and probability that new user accesses this cell again.
It is of course also possible to simultaneously will be any a variety of as the first strategy in (1)-(3), then adjusted according to the first strategy
It is whole.
If step 206, the standard deviation meet standard deviation condition, ratio meets ratio condition, and the average rate of change meets
Second change rate condition is then adjusted according to the second strategy.
If the standard deviation meets standard deviation condition, ratio meets ratio condition, and the average rate of change meets the second variation
Rate condition determines that the RRC connection of cell is created as power and is changed, and M period RRC connection is created as power entirety
It is on a declining curve, and the RRC connection in M period is created as power in rise trend；Then determine corresponding strategy for the second strategy.
Wherein, second strategy can be retracted accordingly according to the first strategy, and second strategy can be wrapped at least
Include following one kind:
(1) cell for reducing the cell selects thresholding.
(2) cell reselection priority of the cell is improved.
(3) the forbidden factors A C-Barring Factor of cell and the forbidden time AC- of cell of the cell are dynamically adjusted
Barring Time。
Wherein, the step-length to retract every time can determine as desired.
Similar, arbitrarily a variety of in (1)-(3) it will can also be used as the second strategy simultaneously, then be carried out according to the second strategy
Adjustment.
If step 207, the standard deviation meet standard deviation condition, ratio meets ratio condition, and the average rate of change meets
Third change rate condition is then adjusted according to third strategy.
If the standard deviation meets standard deviation condition, ratio meets ratio condition, and the average rate of change meets the second variation
Rate condition determines that the RRC connection of cell is created as power and is changed, and M period RRC connection is created as power entirety
It is on a declining curve, and the RRC connection in M period is created as power severe exacerbation；It can determine that the resource allocation of cell occurs at this time
Failure then can determine that corresponding strategy is third strategy, then be adjusted according to third strategy.
Wherein, third strategy be open the cell cell forbid access switch, refuse accessing user.Certainly it allows
