(2) current service cell no longer satisfies the S criterion;
(3) UE detects and is in " non-service area ".
The trigger mechanism of UE cell reselection meets the following conditions:
(1) if Srxlev＜=Sintrasearch, UE need to carry out common frequency measurement;
(2) if Srxlev＜=Sintersearch, UE need to carry out different-frequency measure;
(3) if Srxlev＜=SsearchRAT, UE carries out isosystem measurement.
Wherein, Sintrasearc is that the co-frequency cell gravity treatment starts thresholding, and Sintersearch is that the alien-frequency district gravity treatment starts thresholding, and SsearchRAT is that different system cell gravity treatment starts thresholding.

Mainly there is following shortcoming in the cell re-selection mechanism that present UE under the TD-SCDMA network mainly depends on the network side parameters:
1, the cell reselection threshold parameter of network side arranges singlely, can't the terminal of different performance be optimized.
2, place one's entire reliance upon the network side setting parameter and do not consider terminal capabilities difference, easily cause differentiating UE cell reselection mortality high.
3, the easy delay of cell reselection differentiation and lag time are difficult to control, and easily cause ping-pong reselection.
4, the delay of cell reselection and the sluggish cell paging failure that easily causes network side.
5, different manufacturers, dissimilar terminal can cause the stiff of cell re-selection mechanism at the performance difference of receiving and transmitting signal, cause the low of cell reselection judgement usefulness.
6, network side gravity treatment thresholding arranges and singlely must cause in time gravity treatment of terminal, causes the even problem such as trawlnet of gravity treatment failure.

Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
The method flow diagram of the adjustment cell reselection parameters that Fig. 1 provides for the embodiment of the present invention one, as shown in Figure 1, its concrete steps are as follows:
Step 101: for the UE of each terminal class, such UE is placed on a plurality of positions, for each position, measure such UE at the measurement RSCP of this locational PCCPCH, calculate simultaneously such UE at the theoretical RSCP of this locational PCCPCH, theory of computation RSCP and the difference of measuring RSCP are called for short the RSCP difference.
Measurement RSCP and the theoretical RSCP of UE can obtain by prior art.
Can according to the manufacturer of UE, terminal type, chip type etc., UE be divided into different terminal class.
Step 102: for the UE of each terminal class, calculate such UE at the mean value of all locational RSCP differences.
Step 103: the mean value to the RSCP difference of UE of all categories compares, according to comparative result, determine the adjusting range of each cell reselection parameters of UE of all categories, each cell reselection parameters to UE of all categories is adjusted, and the corresponding relation of each cell reselection parameters of this classification UE after all terminal classes are identified and adjust is configured on RNC.
Particularly, cell reselection parameters comprises: the co-frequency cell gravity treatment starts thresholding Sintrasearc, the alien-frequency district gravity treatment starts thresholding Sintersearch, different system cell gravity treatment startup thresholding SsearchRAT, gravity treatment power R value, gravity treatment skew thresholding etc.
Wherein: for the UE of arbitrary classification, the mean value of the RSCP difference of this classification UE is less, the performance that this classification UE is described is better, and the adjusting range of its Sintrasearc, Sintersearch, SsearchRAT, R value should be larger, and the adjusting range of gravity treatment skew thresholding should be less.Wherein, adjusting range is always positive number.Particularly, for each reselecting parameters, can be in advance for the mean value of the RSCP difference of different range arranges different adjusting ranges, concrete adjusting range value can be rule of thumb or test of many times determine.For example: for Sintrasearc, can arrange: when the mean value of RSCP difference at (0, RSCP
Diff1] during scope, adjusting range is S1; When the mean value of RSCP difference at (RSCP
Diff1, RSCP
Diff2] time, adjusting range is S2; When the mean value of RSCP difference at (RSCP
Diff2, RSCP
Diff3] time, adjusting range is S3; ..., wherein, 0＜RSCP
Diff1＜RSCP
Diff2＜RSCP
Diff3＜..., S1＞S2＞S3＞....
Step 104: when the UE initiating business request, the corresponding relation of each cell reselection parameters of this classification UE after RNC identifies all terminal classes and adjust sends to this UE by system information broadcast (SIB, System Information Broadcast) 3 message.
Here, it is to be noted, for cell reselection parameters: Sintrasearc, Sintersearch, SsearchRAT and gravity treatment skew thresholding, RNC can be according to adjusting range and current each parameter value of each parameter, parameter value after directly being adjusted is handed down to UE with the parameter value after adjusting by SIB3 message; But for the R value, because the R value is calculated by UE, therefore, RNC can only be handed down to UE by SIB3 message with the adjusting range of R value,, according to this adjusting range the R value that calculates is adjusted by UE.
Step 105:UE receives SIB3 message, with the International Mobile Equipment Identity code (IMEI of self, International Mobile Equipment Identity) with this message in each terminal class sign mate, if on coupling, each cell reselection parameters that this terminal class sign is corresponding as self current cell reselection parameters, is carried out cell reselection according to this cell reselection parameters.
Embodiment illustrated in fig. 1 can periodically carrying out also can carry out as required immediately.
The method flow diagram of the adjustment cell reselection parameters that Fig. 2 provides for the embodiment of the present invention two, as shown in Figure 2, its concrete steps are as follows:
Step 200: for arbitrary UE, during this UE initial service access, RNC sends to this UE by SIB3 message with the default cell reselecting parameters that self configures.
Here, the default cell reselecting parameters of the upper configuration of RNC namely is pre-configured in the cell reselection parameters on RNC.For all UE, the default cell reselecting parameters is identical.
Step 201: for arbitrary UE, Measuring Time trail (the TA that this UE periodically reports the IMEI of self and self measures to RNC, Time Advance), the measurement RSCP of PCCPCH, simultaneously, the base station periodically reports the time of advent (TOA, Time of Arrival) and the TA deviate of this UE to RNC.
UE can report RNC with the IMEI of self by the identity response in position updating process (Identity Response) message.
Step 202:RNC determines the terminal class of this UE according to the IMEI that this UE reports, and TOA and the TA deviate of this UE that the TA that reports according to this UE and base station report are calculated the theoretical RSCP of the PCCPCH of this UE.
Step 203:RNC calculates the theoretical RSCP and the difference of measuring RSCP of this UE, is called for short the RSCP difference.
Step 204: for each terminal class, the mean value that belongs to the RSCP difference of such other all UE in the RNC calculating book cycle, according to this mean value, determine the adjusting range of current each cell reselection parameters of this classification UE, each cell reselection parameters of this classification UE is adjusted.
Cell reselection parameters comprises: the co-frequency cell gravity treatment starts thresholding Sintrasearc, the alien-frequency district gravity treatment starts thresholding Sintersearch, different system cell gravity treatment startup thresholding SsearchRAT, R value, gravity treatment skew thresholding etc.
For arbitrary class UE, the mean value of RSCP difference is less, illustrates that the performance of such UE is better, and the adjusting range of its Sintrasearc, Sintersearch, SsearchRAT, R value should be larger, and the adjusting range of gravity treatment skew thresholding should be less.Wherein, adjusting range is always positive number.Particularly, for each reselecting parameters, can be in advance for the mean value of the RSCP difference of different range arranges different adjusting ranges, concrete adjusting range value can be rule of thumb or test of many times determine.
The corresponding relation of each cell reselection parameters step 205:RNC adjusts all terminal class signs with this classification UE after sends to each UE by SIB3 message.
Equally, for cell reselection parameters: Sintrasearc, Sintersearch, SsearchRAT and gravity treatment skew thresholding, RNC can be according to adjusting range and current each parameter value of each parameter, and the parameter value after directly being adjusted is handed down to UE with the parameter value after adjusting by SIB3 message; But for the R value, because the R value is calculated by UE, therefore, RNC can only be handed down to UE by SIB3 message with the adjusting range of R value,, according to this adjusting range the R value that calculates is adjusted by UE.
Step 206:UE receives SIB3 message, the IMEI of self and each terminal class sign in this message are mated, if on coupling, each cell reselection parameters that this terminal class sign is corresponding as self current cell reselection parameters, is carried out cell reselection according to this cell reselection parameters.
Below provide the application example that an application drawing 1 or Fig. 2 embodiment carry out cell reselection:
The residence reselecting flow chart that Fig. 3 provides for the embodiment of the present invention, as shown in Figure 3, its concrete steps are as follows:
Step 301: when UE finds that current service cell can not normally provide service, start cell reselection process.
For example: when UE find that current service cell is hindered or the Srxlev of a N continuous DRS cycle current service cell all less than or equal to 0 the time, definite current service cell can not normally provide service.N is default positive integer.
Step 302:UE measures the RSCP of each neighbor cell, according to the measurement RSCP of each neighbor cell, calculates Srxlev and the Rn value of each neighbor cell.
Here, for arbitrary neighbor cell, the Rn value=Qmeas of this neighbor cell, n-Qoffsets, n
Wherein, Qmeas, n are the RSCP of the neighbor cell that records on P-CCPCH; Qoffsets, the side-play amount when n is cell reselection between current service cell and this neighbor cell is broadcasted by system message.
Step 303:UE selects to satisfy the neighbor cell of the first preselected conditions according to Srxlev and the Rn value of each neighbor cell, according to the Rn value of each neighbor cell, the neighbor cell that satisfies the first preselected conditions is carried out priority queueing.
First preselected conditions here is often referred to: Srxlev＞0 and Rn＞0.
When neighbor cell was carried out priority queueing, normally the R value more reached, and more came the front.
The adjusting range of the R value that step 304:UE sends recently according to RNC is adjusted the Rn value of the highest neighbor cell of priority.
Step 305:UE attempts resident in the highest neighbor cell of priority according to the Rn value after adjusting.
Here, in step 301, UE can start a timer T when starting cell reselection process usually, and before timer T was overtime, UE can repeated execution of steps 302～305.If neighbor cell B continuous N time is chosen as the highest neighbor cell of priority, and all satisfy: the Rs value of the Rn value after the adjustment of residential quarter B-current service cell S＞gravity treatment is offset thresholding at every turn, definite re-selecting cell successfully, UE is resident in the B of residential quarter; Otherwise, determine the cell reselection failure, UE can stop cell reselection, carries out the initial cell selection course in current public land mobile network (PLMN, Public Land Mobile Network), selects persistent district.Wherein, Rs=Qmeas, s+Qhysts, Qmeas, s is the RSCP of the current service cell that records on P-CCPCH, Qhysts is the lag parameter of current service cell, being obtained by system message broadcasting.
Step 306: when UE finds that current service cell can normally provide service, according to Sintrasearc, Sintersearch, the SsearchRAT that RNC sends recently, select to satisfy the neighbor cell of default measurement triggering condition.
Even current service cell can normally provide service, UE also can seek better residential quarter and come resident.Here, the measurement triggering condition is:
(1) when having carried Sintrasearch in current SIB3 message:
If Srxlev＞Sintrasearch, UE does not need to carry out common frequency measurement;
If Srxlev≤Sintrasearch, terminal need to be carried out common frequency measurement.
When not carrying Sintrasearch in current SIB3 message, UE need to carry out common frequency measurement.
(2) when having carried Sintersearch in current SIB3 message:
If Srxlev＞Sintersearch, UE do not need to carry out different-frequency measure;
If Srxlev≤Sintersearch, UE need to carry out different-frequency measure.
When not carrying Sintersearch in current SIB3 message, UE need to carry out different-frequency measure.
(3) if Srxlev≤SsearchRAT, UE need to carry out isosystem measurement;
Step 307:UE measures the RSCP of the neighbor cell that satisfies default measurement triggering condition, and calculates Srxlev, the Rn value of each neighbor cell, and according to the Rn value, the neighbor cell of selecting to satisfy the second preselected conditions carries out priority queueing.
Here second in advance condition can adopt condition in existing protocol.
When neighbor cell was carried out priority queueing, normally the Rn value was larger, more came the front.
Step 308:UE attempts resident in the highest neighbor cell of priority according to the gravity treatment skew thresholding that RNC sends recently.
If neighbor cell C continuous N time is chosen as the highest neighbor cell of priority, and all satisfy: the Rs value of the Rn value of residential quarter C-current service cell S＞gravity treatment is offset thresholding at every turn, definite re-selecting cell successfully, UE is resident in the C of residential quarter; Otherwise, determine the cell reselection failure, UE can continue to reside in current service cell S.
