Embodiment
It is below in conjunction with the accompanying drawings and specific real to enable the above-mentioned purpose of the application, feature and advantage more obvious understandable
Mode is applied to be described in further detail the application.
One of core idea of the embodiment of the present application is, when adjacent cell is event cell, first judges in measurement report
Whether the pilot value of event cell is had, if UE just is not switched into event cell.If so, then determine whether time cell
Received signal strength value subtracts whether corresponding penalty value meets to cut thresholding, if satisfied, UE then is switched into event cell
Reference picture 1, a kind of step flow chart of cell switching method embodiment 1 of the application is shown, can specifically be wrapped
Include following steps：
Step 101, the measurement report of reported by user equipment UE is obtained；
The corresponding adjacent area of RNC sending measurings control information (Measurement Control) configuration UE progress (including service is small
Area) measurement, measuring control information：Trigger condition including measurement report, and need the measurement event performed.When UE has found
After meeting the condition that measurement reports, corresponding measurement result is reported by RNC by measurement report (Measurement Report).
Step 102, Target cell is determined according to measurement report, and determines the current serving cells of the UE；
Measurement report includes the information of each measurement event of UE current service cells and adjacent cell, and RNC is according to survey
The information of amount event can will be event cell as Target cell.
Step 103, judge whether there is the pilot value of the Target cell in measurement report；
Pilot value specifically refers to PCCPCH-RSCP (Primary Common Control Physical Channe-
Received Signal Code Power, Primary Common Control Physical Channel received signal code power).RSCP is to be directed to some code
The receiving power in road.PCCPCH-RSCP is to refer to the received signal code power for Primary Common Control Physical Channel PCCPCH.
Step 104, if not having, by the UE from the tangential Target cell of the serving cell；
In outfield (commercial public network), it sometimes appear that UE not reported event cell RSCP situation, although causing event
Cell RSCP is strong, and resident serving cell RSCP is very weak, but still can not trigger switching, influences user's perception.Therefore, can be with
When not receiving the pilot value of Target cell, by the directly tangential Target cells for not reporting pilot value of UE.
Step 105, if so, then obtaining the received signal strength value of the Target cell；
If there is the pilot value of Target cell in audit report, the reception signal that Target cell is obtained from measurement report is strong
Angle value.
Specifically, if cell is TD-SCDMA (Time Division-Synchronous Code Division
Multiple Access, TD SDMA) cell, then using PCCPCH-RSCP as received signal strength value.
PCCPCH-RSCP refers to the received signal code power for Primary Common Control Physical Channel PCCPCH.
If cell is GSM (Global System for Mobile communication, global mobile communication system
System) cell, then made using RSSI (Received Signal Strength Indication, the signal intensity instruction of reception)
For received signal strength value.RSSI represents all signal power sums that UE receives in some time slot on some frequency,
RSSI cannot distinguish between this cell signal power and other cell signal powers.
Step 106, judge that the received signal strength value subtracts, the difference of the penalty value of the default Target cell,
Whether default Target cell incision thresholding is more than or equal to；
In the embodiment of the present application, in RNC systems, a penalty value is provided with to each cell.Judging whether to cut
When entering cell, RNC systems subtract the received signal strength value of cell, penalty value corresponding to cell, and the difference for judging to obtain is
It is no to be more than or equal to incision thresholding corresponding to the cell, if it is, by UE from the tangential cell of original serving cell.
Thresholding is cut if less than cell, then without switching.
Step 107, if so, the UE then is switched into the Target cell from the serving cell.
In the embodiment of the present application, when adjacent cell is event cell, using for the adjacent cell of event cell it is small as target
Area.First judge whether there is the pilot value of Target cell in measurement report；If UE no, is switched into Target cell.If so, then
Determine whether that the received signal strength value of Target cell subtracts whether corresponding penalty value meets to cut thresholding, if satisfied, then
UE is switched into Target cell.Judge whether that needs switch over by setting Rule of judgment in the embodiment of the present application, avoid
UE frequent switchings, the scene for soldier's pang switching occur is avoided, RNC systems is alleviated and switches over processing load, and improve
User perception.

Step 203, judge whether there is the pilot value of the Target cell in measurement report；
Step 204, if not having, by the UE from the tangential Target cell of the serving cell；
Step 205, if so, then obtaining the received signal strength value of the Target cell；
Step 206, judge that the received signal strength value subtracts, the difference of the penalty value of the default Target cell,
Whether default Target cell incision thresholding is more than or equal to；
Step 207, if so, the UE then is switched into the Target cell from the serving cell；
Step 208, after the completion of switching, penalty value corresponding to the serving cell is increased, and start and be directed to the service
The punishment timer of cell；
After completing once to switch, in RNC systems, it can all increase for punishing as the serving cell for cutting out cell
Penalties.And serving cell is directed to, start a punishment timer.
Specifically, being set with punishment step-length in RNC, often complete once to switch, just increase penalty value a punishment step-length.
The span for punishing step-length can be 1-15dB；Preferably, step-length is punished using 3dB by default.Punishment timer is determined

The penalty value of cell is arranged to the default maximum penalty value.
After penalty value is increased, penalty value exceedes default maximum penalty value, then using the penalty value of maximum as cell pair
The penalty value answered.
Specifically, the span of maximum penalty value can be 1-60dB；Preferably, punished using 30dB as maximum
Value.
Step 209, before the punishment timer expiry, penalty value corresponding to the serving cell is preserved.
Before timer expiry, the penalty value of corresponding serving cell remains effective.
Step 210, after the punishment timer expiry, penalty value corresponding to the serving cell is reset；
When punishing that timer reaches corresponding time-out time, then penalty value corresponding to cell, the punishment of cell initial are reset
Value is arranged to 0.
For each UE, RNC needs to safeguard the pingpang handoff penalty value and pingpang handoff of serving cell and each adjacent cell
Punish timer, initial pingpang handoff penalty value be 0, the parameter for safeguarding serving cell be because be likely to occur timer expiry it
It is preceding to cut out situation about cutting into repeatedly.In addition, if the cell once cut out before has not been the adjacent cell of current service cell
, but pingpang handoff punishment timer is still effective, then stills need to preserve the pingpang handoff penalty value of the cell and table tennis is cut
Change punishment timer
In a kind of preferred exemplary of the embodiment of the present application, described method can also comprise the following steps：
When corresponding to the serving cell punish timer expiry before, serving cell described in UE from other cell switchbacks,
And when being cut out again from the serving cell, increase penalty value corresponding to the serving cell, and restart the serving cell
Corresponding punishment timer.If after increasing penalty value, penalty value exceedes default maximum penalty value, then by the penalty value of maximum
As penalty value corresponding to cell.
In order that those skilled in the art better understood when the embodiment of the present invention, below by an example to this hair
Bright embodiment is illustrated：
Assuming that there is cell ABC adjacent cells each other, the punishment step-length that RNC is set is S.
Cell A is UE initial service cell.In original state, penalty value Qa corresponding to cell A is 0；Corresponding to cell B
Penalty value Qb is 0；Penalty value corresponding to cell C is Qc0；Punishment timer Ta is closed corresponding to cell A；Punished corresponding to cell B
Timer Tb is penalized to close；Punishment timer Tc is closed corresponding to cell C.
UE is switched into cell B from cell A.Now, penalty value Qa corresponding to cell A is S；Penalty value corresponding to cell B
Qb is 0；Penalty value Qc corresponding to cell C is 0；Punishment timer Ta starts corresponding to cell A；Punishment timing corresponding to cell B
Device Tb is closed；Punishment timer Tc is closed corresponding to cell C.
Before Ta time-out, UE is switched back into cell A from cell B.Now, penalty value Qa corresponding to cell A is S；B pairs of cell
The penalty value Qb answered is S；Penalty value Qc corresponding to cell C is 0；Punishment timer Ta starts corresponding to cell A；Cell B is corresponding
Punishment timer Tb start；Punishment timer Tc is closed corresponding to cell C.
Before Ta time-out, UE is switched into cell C from cell A.Now, penalty value Qa corresponding to cell A is 2S；Cell B
Corresponding penalty value Qb is S；Penalty value Qc corresponding to cell C is 0；Punishment timer Ta is restarted corresponding to cell A；Cell B
Corresponding punishment timer Tb starts；Punishment timer Tc is closed corresponding to cell C.
Ta time-out, penalty value Qa corresponding to cell A are 0；Penalty value Qb corresponding to cell B is S；Punished corresponding to cell C
Value Qc is 0；Punishment timer Ta is closed corresponding to cell A；Punishment timer Tb starts corresponding to cell B；Punished corresponding to cell C
Timer Tc is penalized to close.
In a kind of preferred exemplary of the embodiment of the present application, described method can also comprise the following steps：
If the serving cell and Target cell of current handover procedures belong to different signal command boards, the first signal command board will be belonged to
, punishment timer ends corresponding to cell are had not timed out, and corresponding penalty value is reset；First signal command board is worked as to be described
Signal command board belonging to the serving cell of preceding handoff procedure；It is described to have not timed out cell having not for the handoff procedure before the UE
The serving cell of time-out punishment timer.
For example, carrying out first time switching first, the cell A that UE is subordinated to business board A is switched to and is belonged to the small of business board A
Area B；After the completion of switching, increase is directed to cell A penalty value Qa, and punishment timer Ta of the activation pin to cell A.
Then carry out second to switch, the cell B that UE is subordinated to business board A is switched to and belonged to business board C cell C；
After the completion of switching, increase is directed to cell B penalty value Qb, and punishment timer Tb of the activation pin to cell B.
Second of handoff procedure is current handover procedures, because cell C and cell B belongs to different signal command boards, therefore is worked as
Preceding switching belongs to inter-broad handoff.Signal command board A is the signal command board belonging to serving cell (cell B) in current handover procedures.
Cut out in source plate UE in multiple cells, it is understood that there may be the cell cut out before, which also has, punishes that timer is not super
When, at this moment only preserve penalty value and punishment timer that last time cuts out cell.
If for example, for the punishment timer for cutting out cell (cell A) of handoff procedure before UE, still have not timed out, i.e.,
Cell A is to have not timed out cell.RNC will be reset for cell A penalty value by for cell A punishment timer ends.
After inter-broad handoff process, RNC only preserves the punishment timer of the serving cell of UE current handover procedures and right
The penalty value answered.
If inter-broad handoff, i.e., the serving cell of current handover procedures and Target cell belong to same signal command board,
Then retain the punishment timer having not timed out for cutting out cell of each switching of UE, and corresponding penalty value.
