Embodiment one
In the present embodiment, cell pre-configuration is carried out to UE by RRC dedicated signaling by eNB.
As shown in figure 4, between eNB interaction UE switching historical information or cell configure historical information, by eNB1 Lai
The switching historical information of UE or the historical information of cell configuration are collected, when eNB1 has obtained the regular process of some UE
After the statistical result of cell1-cell5, and when cell1 services the UE again, eNB1 belonging to cell1 will be cell1-
The cell access parameters of cell5 are all sent to UE, and UE retains these cell access parameters after receiving these cell access parameters.
Cell management scene:
When passing through cell1-cell5, PCell (main plot) has not been changed UE always, is cell0, and cell1-cell5 makees
For the SCell (secondary cell) of UE.
When UE selects cell1 as serving cell (alternatively, as eNB0 belonging to UE enters cell0), belonging to cell1
ENB1 according to the serving cell historical information and/or traffic path of UE predict UE will be by cell1-cell5, by cell1-
The community configured information of cell5 is sent to UE by RRC connection reconfiguration message, as wherein configuration information relevant to SCell,
UE feeding back ACK/nack message is to eNB1；It is also possible to eNB0 belonging to cell0 to believe the cell access parameters of cell1-cell5
Breath is sent to UE by RRC connection reconfiguration message, as wherein configuration information relevant to SCell, UE feeding back ACK/NACK letter
It ceases to eNB0.
Hereafter, it with the movement of UE, gives the correct time when in UE triggering measurement, UE does not carry out Signalling exchange with eNB2, automatically begins to
Cell2 is accessed using the cell access parameters of the cell2 of storage, for the cell access parameters of used cell1 before,
UE can choose deletion or continue to retain.When eNB1 receives the measurement report that UE is reported, network side begins to use cell0+
Cell2 carries out data transmission UE.
Cell handoff scenario:
Cell switching occurs when passing through cell1-cell5 for UE.When UE selects cell1 as serving cell, cell1 institute
The eNB1 of category predicts that UE will be by cell1-cell5, by cell1- according to the serving cell historical information and/or traffic path of UE
The community configured information of cell5 is sent to UE by RRC connection reconfiguration message, matches confidence as wherein relevant to cell switching
It ceases, i.e. the information for including in IE MobilityControlInfo, UE feeding back ACK/nack message is to eNB1.
Hereafter, it with the movement of UE, gives the correct time when in UE triggering measurement, UE does not carry out Signalling exchange with eNB2, automatically begins to
Cell2 is accessed using the cell access parameters of the cell2 of storage, for the cell access parameters of used cell1 before,
UE can choose deletion or continue to retain.When eNB1 receives the measurement report that UE is reported, eNB1 is (upper and lower by UE context
Text) information passes to eNB2, and the data not being transmitted are passed to eNB2 simultaneously, and after UE access eNB2, eNB2 is opened
Beginning carries out data transmission the UE.
Embodiment two:
In the present embodiment, cell pre-configuration is carried out to UE by broadcast mode or multicast mode by eNB.
As shown in figure 5, if there is a large number of users behavior unanimous circumstances, if a large number of users is all got on the bus at same station,
And get off at same station, then it is prewired can to carry out cell to corresponding UE by broadcast mode or multicast mode for network side
It sets.
Cell management scene (by taking broadcast mode as an example):
When passing through cell1-cell5, PCell has not been changed UE always, is cell0, and cell1-cell5 is used as UE's
SCell.ENB0 predicts that a large amount of UE will include in the broadcast message of eNB0 by cell1-cell5 according to the traffic path of UE
The community configured information of cell1-cell5, as eNB0 belonging to UE enters cell0, UE is read from the broadcast message of eNB0
The cell access parameters of cell1-cell5.Hereafter, it with the movement of UE, gives the correct time when in UE triggering measurement, is entered from cell1
When cell2, UE does not carry out Signalling exchange with eNB2, automatically begins to access using the cell access parameters of the cell2 of storage
Cell2, for the cell access parameters of used cell1 before, UE can choose deletion or continue to retain.When eNB1 is received
When the measurement report reported to UE, network side begins to use cell0+cell2 to carry out data transmission UE.
Cell handoff scenario (by taking multicast mode as an example):
Cell switching occurs when passing through cell1-cell5 for UE.ENB0 has in advance carried out the UE with same routes
Marshalling, when there is the UE of a certain number of identical marshallings to enter eNB0 belonging to cell0, eNB0 will will with multicast mode
The community configured information of cell1-cell5 is sent to these UE, and UE feeding back ACK/nack message is to eNB0.Hereafter, with UE's
It is mobile, it gives the correct time when in UE triggering measurement, when entering cell2 from cell1, UE does not carry out Signalling exchange with eNB2, automatically begins to
Cell2 is accessed using the cell access parameters of the cell2 of storage, the configuration for used cell1 before, UE can be selected
It selects deletion or continues to retain.When eNB1 receives the measurement report that UE is reported, eNB1 passes to UE context information
ENB2, and the data not being transmitted are passed into eNB2 simultaneously, after UE access eNB2, eNB2 starts to count the UE
According to transmission.
Embodiment three
In the present embodiment, eNB carries out cell pre-configuration to UE according to the common cell of UE.
As shown in fig. 6, the historical information that eNB is configured according to the switching historical information or cell of UE, available UE connect
Indegree is greater than the common cell of preset value, and for commonly using the cell access parameters of cell, UE can voluntarily retain, alternatively,
When eNB sends community configured information to UE, instruction UE wherein which be common cell, i.e. instruction which cell access parameters of UE exist
Using finishing or temporarily needing to continue to retain when not in use, in this way when accessing common cell after UE, it is not necessary to again with commonly use it is small
The eNB in area carries out Signalling exchange, directly can access common cell using the cell of the common cell of storage.
For example, when user by the direction cell1 by bus to cell5 when, when UE selects cell1 as serving cell, cell1
Affiliated eNB1 predicts that UE will be by cell1-cell5, by the community configured information of cell1-cell5 according to the traffic path of UE
Be sent to UE, and indicate that cell1-cell5 is common cell, UE after the cell access parameters using cell1-cell5, after
The cell access parameters of cell1-cell5 are stayed in continuation of insurance, in this way in user by the direction cell5 by bus to cell1 when, network side is not required to
The cell access parameters of these cells are issued for UE again, UE voluntarily can access this using the cell access parameters retained
A little cells.In this way, the signaling overheads of network side can be further reduced.
By taking cell management scene as an example, when passing through cell5-cell1, PCell has not been changed UE always, is cell0,
