Connect and switch to Target cell, the possibility of UE handoff failures can be reduced and recover UE and internetwork business in time.
Fig. 2 is a kind of flow chart of the cell switching method according to another exemplary embodiment.The cell switching side
Method is applied in UE, and the cell switching method can include following several steps.
In step 201, the measurement configuration information for carrying the first measurement cell list that network side equipment sends 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 UE present access subzones 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
It is 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 apparatus, when needs and network carry out business, nothing is set up with the network side equipment
Line resources control (Radio Resource Control, RRC) is connected.Wherein, the RRC is connected as between UE and the network side equipment
The carrying of RRC control messages is transmitted, UE and the network side equipment are capable of achieving communication service using RRC connections.
After RRC connections are set up, the network side equipment can be that the UE is determined at least from the adjacent cell of UE access cells
One cell to be measured, measures cell list, to UE using the cell ID generation first of above-mentioned at least one cell to be measured
Issue the measurement configuration information for carrying the first measurement cell list.
In step 202., the cell of UE history handoff failures is determined, detects whether the first measurement cell list includes
The cell ID of the cell of above-mentioned UE history handoff failure.
UE switch to every time network side equipment indicate switching Target cell fail when, by the cell mark of the Target cell
Knowledge is recorded as the cell ID of UE history handoff failure cells.
Then this step can be：UE obtains its record after the measurement configuration information for receiving network side equipment transmission
The cell ID of history handoff failure cell, detects whether the first measurement cell list includes that the UE history switching of its record is lost
Lose the cell ID of cell.
Optionally, implementing for this step can be：UE obtains the cell ID in blacklist list, blacklist row
Table is used to record the cell ID of the UE history handoff failure cells；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 handoff failures,
The cell ID of the cell for deleting above-mentioned UE history handoff failure from the first measurement cell list obtains the second measurement cell
List.
In step 204, the corresponding cell of each cell ID that the second measurement cell list includes is measured
To measurement report, the measurement report is sent to network side equipment, make network side equipment small from the second measurement according to the measurement report
Target cell is determined in the corresponding cell of cell ID that area's list includes, step 206 is performed.
UE generally detect its it is relatively low with communication quality between the network side equipment in the case of currently connect, it is necessary to depart from
The cell for entering, switches to other cells and continues business to improve communication quality.Specifically, UE at it between the network side equipment
When communication quality is relatively low, obtains second and measure the corresponding cell of each cell ID that includes of cell list as measurement cell,
RRM (Radio Resource Management, RRM) measurement is carried out to these measurement cells, obtains including
The measurement report of the channel quality information of measurement cell is stated, the measurement report is sent to the network side equipment.
It is that the UE determines Target cell from these measurement cells that the network side equipment is based on measurement report, is sent to UE
The RRC connections for carrying the access parameter of Target cell reconfigure (English：Connection Reconfiguration) message,
So that UE can access Target cell using the access parameter, UE matches somebody with somebody again in the case where Target cell is accessed according to RRC connections
Put message network side equipment corresponding with Target cell and set up RRC connections, continue it and lead to internetwork communication service and raising
Letter quality.
In step 205, UE detect the first measurement cell list including UE history handoff failures cell it is small
When area identifies, RRM measurements are carried out to the corresponding cell of each cell ID that the first measurement cell list includes and obtains measurement report
Accuse, the measurement report is sent to network side equipment, make network side equipment according to the measurement report from the first measurement cell list bag
Determine Target cell in the corresponding cell of cell ID for including.
In step 206, UE receives the access parameter of the Target cell that network side equipment sends, and determines the small of Target cell
Area identifies whether to be located in banned list.
UE receives the RRC connection reconfiguration messages of the access parameter for carrying Target cell, is generally wrapped in the access parameter
Cell ID and frequency containing Target cell.UE obtain its maintenance forbid (English：Forbidden) list, the banned list
The cell ID that UE forbids accessing cell is have recorded, detects whether the cell ID of 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.
For example, when UE detects that the cell ID a of Target cell is in banned list, will be small in banned list
Area mark a it is corresponding it is heavy be labeled as TRUE with flag bit, the banned list is as shown in table 1.
Table 1
| Cell ID | Match somebody with somebody flag again | Switching flag |
| a | TRUE | |
| b | ||
| c |
UE performs step 207 or step 208 after step 206 is performed.
It should be noted that UE is when the cell ID for detecting Target cell is located at banned list, can be in banned list
In mark the cell ID of the Target cell in several ways, to show that the UE starts the stream for switching to the Target cell
Journey, for example, it is also possible to add special identifier symbol " # " at the cell ID, the present embodiment no longer repeats mark mode, no one by one
Make specific restriction 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
The only cell ID of list including Target cell, then from banned list delete target cell cell ID.
UE starts switching after the access parameter of Target cell of network side equipment transmission is received according to the access parameter
To the flow of Target cell.
UE detect Target cell mark be located at banned list in the case of, after successful switch to Target cell,
The cell ID of delete target cell from banned list, and reconfigured according to the RRC connections received from the network side equipment
Message network side equipment corresponding with Target cell sets up RRC connections, to continue it with 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 for reconfiguring in remove ban list.For example, again with mark in UE remove bans list 1
It is the cell ID of TRUE to know position, and the banned list after deletion is as indicated in the chart 2.
Table 2
| Cell ID | Match somebody with somebody flag again | Switching flag |
| b | ||
| c |
Optionally, step 207 could alternatively be：Cell switching is 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 detect Target cell cell ID be located at banned list in the case of, in successful switch to Target cell
Afterwards, the cell ID is labeled as handover success in banned list, and according to the RRC connections received from the network side equipment
Reconfiguration message network side equipment corresponding with Target cell sets up RRC connections, to continue it with 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 for reconfiguring labeled as handover success in banned list.For example, UE is in successful switch
To Target cell, will again match somebody with somebody flag for the switching flag of the cell ID of TRUE is labeled as TRUE, this is heavy with mark
The TRUE of position is revised as FALSE, and amended banned list is as shown in table 3.
Table 3
| Cell ID | Match somebody with somebody flag again | Switching flag |
| 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 into
After work(switches to Target cell, the cell ID of the Target cell can be in several ways marked in banned list, to show
The UE once successful switch to the Target cell, for example, UE can also add special identifier symbol " * " at the cell ID, this
Embodiment no longer repeats mark mode, does not make specific restriction to mark mode one by one.
In a step 208, UE carries out cell switching according to the access parameter, is switching to Target cell failure and is forbidding row
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.Specifically, UE is marked as reconfiguring in obtaining banned list
Cell ID, by the cell ID added in blacklist list.
For example, UE, will when Target cell failure is switched to and banned list includes the cell ID of Target cell
Again with flag for the cell ID of TRUE is added in blacklist list, then the heavy TRUE with flag is revised as
FALSE。
Optionally, above-mentioned steps 208 are that one kind that UE history handoff failure cells are recorded in the application realizes example, except
The example, the application can also be realized using other modes.In a kind of mode, step 208 could alternatively be：Connect according to this
Entering parameter carries out cell switching, when Target cell failure is switched to and banned list includes the cell ID of Target cell,
The cell ID of Target cell is labeled as handoff failure in banned list.Meanwhile, the implementation of step 202 can be replaced
For：The cell ID of handoff failure is marked as in acquisition banned list, detects whether the first measurement cell list includes upper
State the cell ID that handoff failure is marked as in banned list.
In the case where the cell ID for detecting Target cell is located at banned list, UE is switching to Target cell mistake to UE
When losing, the cell ID is labeled as handoff failure in banned list.
Specifically, UE will be marked as the cell ID for reconfiguring after Target cell failure is switched in banned list
Labeled as handoff failure.For example, when Target cell failure is switched to, it is the cell ID of TRUE that will again match somebody with somebody flag to UE
Switching flag be labeled as FALSE, the heavy TRUE with flag is revised as FALSE, amended banned list such as table 4
It is shown.
Table 4
| Cell ID | Match somebody with somebody flag again | Switching flag |
| a | FALSE | FALSE |
| b | ||
| c |
It should be noted that in the case where the cell ID of Target cell is located at banned list, it is small that UE switches to target
After area's failure, the cell ID of the Target cell can be in several ways marked to be to show the Target cell in banned list
The cell of UE history handoff failures, for example, UE can also be added at the cell ID special identifier symbol "！", the present embodiment is not
Repeat mark mode one by one again, do not make specific restriction to mark mode.
In sum, the cell switching method for being provided in the embodiment of the present disclosure, by by the cell of UE history handoff failures
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 of the cell that UE history handoff failures are crossed, cell switching is carried out according to the second measurement cell list, keep away
UE is exempted from and has accessed the cell that history handoff failure is crossed again, even if the Target cell that UE is switched to is located in banned list, also directly
Connect and switch to Target cell, the possibility of UE handoff failures can be reduced and recover UE and internetwork business in time.
Further, since in the prior art：When the cell ID for detecting Target cell B in UE is located in the banned list,
UE stops switching to the flow of Target cell B so that UE enters non-service state.After UE enters non-service state, can scan attached
Near cell, therefrom selects the cell for once accessing to be accessed immediately.It will be apparent that UE accesses the possibility of cell-of-origin A again
Property it is very big, it is assumed that UE accesses cell A, and UE may be still relatively low with internetwork communication quality after accessing cell A, it is desired nonetheless to cut
Shift to other cells and continue data service.But, during execution is switched to other cells, the network corresponding to cell A
Side apparatus may still choose the Target cell that cell B switches as UE.When selecting cell B as Target cell, UE is another
Secondary entrance non-service state.Network side equipment indicates the flow that UE switches to cell B to enter repeatedly after so causing UE to access cell A
OK, UE ceaselessly switches between non-service state and service state, and UE hardly can carry out any business with network during this.
In the application, UE in the measurement for carrying the first measurement cell list for receiving network side equipment transmission by matching somebody with somebody confidence every time
During breath, the cell ID of the cell of UE history handoff failures is deleted from the first measurement cell list and obtains the second measurement cell
List, when needing to carry out cell and switching, cell switching is carried out according to the second measurement cell list, it is to avoid UE is accessed go through again
The cell that history handoff failure is crossed, it is to avoid UE ceaselessly switches between non-service state and service state, UE is hardly during this
The problem of any business can be carried out with network, the effect of timely recovery UE and internetwork business has been reached.
In addition, UE to the cell that history handoff failure is crossed by not measuring, network side equipment will not also receive UE
The measurement report of the channel quality information of the cell that handoff failure is crossed, the measurement report that network side equipment is reported according to UE is determined
Target cell also will not UE history handoff failures cross, therefore avoid that UE accesses that history handoff failure crosses again it is small
