A possibility that connecing and switch to Target cell, can reduce UE handover failure and in time recovery UE and internetwork business.
Fig. 2 is a kind of flow chart of the cell switching method shown according to another exemplary embodiment.The cell switching side
Method is applied in UE, which may include the following steps.
In step 201, the measurement configuration information for carrying the first measurement cell list that network side equipment is sent is received,
The first measurement cell list includes the cell ID of at least one cell to be measured.
Wherein, network side equipment can be the corresponding base station in the present access subzone UE or the corresponding wireless access network of the cell
(Radio Access Network, RAN) etc., the base station in long term evolution (Long-Term Evolution, LTE) system
For evolved base station (Evolved Node B, eNB).
Cell ID in the present embodiment can be Physical Cell Identifier (Physical Cell Identifier, PCI).
After the cell of UE access network side equipment, when needing to carry out business with network, nothing is established with the network side equipment
Line resources control (Radio Resource Control, RRC) connection.Wherein, which is connected as between UE and the network side equipment
It transmits the carrying of RRC control message, UE and the network side equipment and connects achievable communication service using the RRC.
After RRC connection is established, which can determine at least from the adjacent cell of the UE access cell for the UE
One cell to be measured generates the first measurement cell list using the cell ID of at least one above-mentioned cell to be measured, to UE
Issue the measurement configuration information for carrying the first measurement cell list.
In step 202, the cell for determining UE history handover failure, detect this first measurement cell list whether include
The cell ID of the cell of above-mentioned UE history handover failure.
UE when switching to the Target cell failure of network side equipment instruction switching every time, by the cell mark of the Target cell
Know and is recorded as the cell ID of UE history handover failure cell.
Then this step can be with are as follows: UE obtains its record after the measurement configuration information for receiving network side equipment transmission
The cell ID of history handover failure cell detects whether the first measurement cell list includes that its UE history switching recorded is lost
Lose the cell ID of cell.
Optionally, the specific implementation of this step can be with are as follows: UE obtains the cell ID in blacklist list, blacklist column
Table is used to record the cell ID of the UE history handover failure cell；Detect whether the first measurement cell list includes above-mentioned black
Cell ID in list list.
In step 203, when the first measurement cell list includes the cell ID of cell of UE history handover failure,
The cell ID for the cell for deleting above-mentioned UE history handover failure from the first measurement cell list obtains the second measurement cell
List.
In step 204, the corresponding cell of each cell ID for including to the second measurement cell list measures
To measurement report, the measurement report is sent to network side equipment, keeps network side equipment small from the second measurement according to the measurement report
Target cell is determined in the corresponding cell of the cell ID that area's list includes, and executes step 206.
UE is needed to be detached from and is currently connect usually in the case where detecting its lower situation of communication quality between the network side equipment
The cell entered switches to other cells and continues business to improve communication quality.Specifically, UE is at it between the network side equipment
When communication quality is lower, obtains the corresponding cell of each cell ID that the second measurement cell list includes and is used as measurement cell,
Wireless resource management (Radio Resource Management, RRM) measurement is carried out to these measurement cells, obtains including upper
The measurement report for stating the channel quality information of measurement cell, is sent to the network side equipment for the measurement report.
It is that the UE determines Target cell from these measurement cells that the network side equipment, which is based on measurement report, is sent out to UE
It send the RRC connection reconfiguration for the access parameter for carrying Target cell to set (English: Connection Reconfiguration) to disappear
Breath, so that UE can access Target cell using the access parameter, UE is in the case where accessing Target cell according to RRC connection weight
Corresponding with the Target cell network side equipment of configuration message establishes RRC connection, continues it with internetwork communication service and improves
Communication quality.
In step 205, UE is detecting that the first measurement cell list does not include the small of the cell of UE history handover failure
When area identifies, RRM measurement is carried out to the corresponding cell of each cell ID that the first measurement cell list includes and obtains measurement report
It accuses, sends the measurement report to network side equipment, network side equipment is made to measure cell list packet from first according to the measurement report
Target cell is determined in the corresponding cell of the cell ID included.
In step 206, UE receives the access parameter for the Target cell that network side equipment is sent, and determines the small of Target cell
Area identifies whether to be located in banned list.
The RRC connection reconfiguration that UE receives the access parameter for carrying Target cell sets message, usually wraps in the access parameter
Cell ID and frequency point containing Target cell.What UE obtained its maintenance forbids (English: forbidden) list, the banned list
The cell ID that UE forbids accessing cell is had recorded, whether the cell ID for detecting Target cell is located in banned list.
Optionally, UE is small by this in banned list when the cell ID for detecting Target cell is located at banned list
Area's mark is labeled as reconfiguring.
It for example, will be small in banned list when UE detects that the cell ID a of Target cell is located in banned list
Area identifies the corresponding reconfiguration flag bit of a and is labeled as TRUE, and the banned list is as shown in table 1.
Table 1
| Cell ID | Marker is reconfigured | Switch marker |
| a | TRUE | |
| b | ||
| c |
UE executes step 207 or step 208 after executing step 206.
It should be noted that UE is when the cell ID for detecting Target cell is located at banned list, it can be in banned list
In mark the cell ID of the Target cell in several ways, switch to the stream of the Target cell to show that the UE is started
Journey, for example, it is also possible to which adding special identifier at the cell ID accords with " # ", the present embodiment no longer repeats mark mode, no one by one
Specific limit is made to mark mode.
In step 207, cell switching is carried out according to the access parameter, after successful switch to Target cell, if the taboo
Only list includes the cell ID of Target cell, then from banned list delete target cell cell ID.
UE starts to switch after receiving the access parameter of Target cell of network side equipment transmission according to the access parameter
To the process of Target cell.
UE is in the case where the mark for detecting Target cell is located at banned list, after successful switch to Target cell,
The cell ID of delete target cell from banned list, and set according to the RRC connection reconfiguration received from the network side equipment
Message network side equipment corresponding with Target cell establishes RRC connection, to continue itself and internetwork communication service.
Specifically, in the case that UE detects that the mark of Target cell is located at banned list, it is small to target in successful switch
Qu Hou is marked as the cell ID reconfigured in remove ban list.For example, mark is reconfigured in UE remove ban list 1
Know the cell ID that position is TRUE, the banned list after deletion is as indicated in the chart 2.
Table 2
| Cell ID | Marker is reconfigured | Switch marker |
| b | ||
| c |
Optionally, step 207 could alternatively be: cell switching be carried out according to the access parameter, in successful switch to target
After cell, if the banned list includes the cell ID of Target cell, by the cell ID of Target cell in banned list
Labeled as handover success.
UE is in the case where the cell ID for detecting Target cell is located at banned list, in successful switch to Target cell
Afterwards, the cell ID is labeled as switching successfully in banned list, and according to the RRC connection received from the network side equipment
Reconfiguration message network side equipment corresponding with Target cell establishes RRC connection, to continue itself and internetwork communication service.
Specifically, in the case that UE detects that the mark of Target cell is located at banned list, it is small to target in successful switch
Qu Hou will be marked as the cell ID reconfigured labeled as handover success in banned list.For example, UE is in successful switch
To Target cell, the switching marker that the cell ID that marker is TRUE is reconfigured is labeled as TRUE, which is identified
The TRUE of position is revised as FALSE, and modified banned list is as shown in table 3.
Table 3
| Cell ID | Marker is reconfigured | Switch marker |
| a | FALSE | TRUE |
| b | ||
| c |
It should be noted that in the present embodiment, in the case where the cell ID of Target cell is located at banned list, UE at
After function switches to Target cell, the cell ID of the Target cell can be marked in several ways, in banned list to show
Once successful switch was to the Target cell by the UE, for example, UE can also add special identifier symbol " * " at the cell ID, originally
Embodiment no longer repeats mark mode one by one, does not make specific limit to mark mode.
In a step 208, UE carries out cell switching according to the access parameter, is switching to Target cell failure and is forbidding arranging
When table includes the cell ID of Target cell, the cell ID of Target cell is added to blacklist list.
UE is switching to Target cell failure in the case where the cell ID for detecting Target cell is located at banned list
When, the cell ID of Target cell is added to blacklist list.It is marked as reconfiguring in banned list specifically, UE is obtained
Cell ID, which is added in blacklist list.
For example, UE, will when switching to Target cell failure and banned list includes the cell ID of Target cell
The cell ID that reconfiguration marker is TRUE is added in blacklist list, then the TRUE of the reconfiguration marker is revised as
FALSE。
Optionally, above-mentioned steps 208 are that a kind of realization example of UE history handover failure cell is recorded in the application, in addition to
The example, the application can also be realized using other modes.In a kind of mode, step 208 be could alternatively be: according to this
Access parameter carries out cell switching, when switching to Target cell failure and banned list includes the cell ID of Target cell,
The cell ID of Target cell is labeled as handover failure in banned list.Meanwhile the implementation of step 202 can be replaced
Are as follows: the cell ID for being marked as handover failure in banned list is obtained, detects whether the first measurement cell list includes upper
State the cell ID that handover failure is marked as in banned list.
For UE in the case where the cell ID for detecting Target cell is located at banned list, UE is switching to Target cell mistake
When losing, the cell ID is labeled as handover failure in banned list.
Specifically, UE will be marked as the cell ID reconfigured after switching to Target cell failure in banned list
Labeled as handover failure.For example, the cell ID that marker is TRUE will be reconfigured when switching to Target cell failure in UE
Switching marker be labeled as FALSE, the TRUE of the reconfiguration marker is revised as FALSE, modified banned list such as table
Shown in 4.
Table 4
| Cell ID | Marker is reconfigured | Switch marker |
| a | FALSE | FALSE |
| b | ||
| c |
It should be noted that it is small that UE switches to target in the case where the cell ID of Target cell is located at banned list
After area's failure, the cell ID of the Target cell can be marked to be to show the Target cell in banned list in several ways
The cell of UE history handover failure, for example, UE can also be added at the cell ID special identifier symbol "！", the present embodiment is not
It repeats mark mode one by one again, specific limit is not made to mark mode.
In conclusion the cell switching method provided in the embodiment of the present disclosure, by by the cell of UE history handover failure
Cell ID from first measurement cell list in delete obtain the second measurement cell list, due to second measurement cell list in
No longer include the cell ID for the cell that UE history handover failure is crossed, cell switching is carried out according to the second measurement cell list, is kept away
UE is exempted from and has accessed the cell that history handover failure is crossed again, even if the Target cell that UE is switched to is located in banned list, also directly
A possibility that connecing and switch to Target cell, can reduce UE handover failure and in time recovery UE and internetwork business.
In addition, due in the prior art: when UE detects that the cell ID of Target cell B is located in the banned list,
UE stops switching to the process of Target cell B, so that UE enters non-service state.After UE enters non-service state, it can scan attached
Close cell therefrom selects the cell once accessed to be accessed immediately.It will be apparent that UE accesses the possibility of source cell A again
Property it is very big, it is assumed that UE access cell A, UE access cell A after may be still lower with internetwork communication quality, it is desired nonetheless to
It switches to other cells and continues data service.But during execution is switched to other cells, net corresponding to cell A
Network side apparatus may still choose the Target cell that cell B switches as UE.When selecting cell B as Target cell, UE is again
Once enter non-service state.The process for causing network side equipment instruction UE after UE access cell A to switch to cell B in this way is anti-
Multiple to carry out, UE ceaselessly switches between non-service state and service state, and UE can hardly be carried out any with network during this
Business.In the application, UE passes through every time in the measurement for carrying the first measurement cell list for receiving network side equipment transmission
When configuration information, the cell ID of the cell of UE history handover failure is deleted from the first measurement cell list and obtains the second survey
Cell list is measured, when needing to carry out cell switching, cell switching is carried out according to the second measurement cell list, avoids UE again
