SCell collection is combined into UE, and this is measured in all adjacent cells reported, the home base station identical cell of its home base station and the UE,
I.e.：Cell4And Cell5, because base station calculates UE in Cell4On RSRQ be 23dB, in Cell5On RSRQ be 20dB, because
This ranking results is：Cell4>Cell5（That is Cell4Priority be more than Cell5）.
Base station this source SCell and mesh for changing is determined according to candidate source SCell set and candidate target SCell set
Mark SCell.So that base station is using first determining that source SCell determines target SCell method again as an example：
First, base station selects the Cell of highest priority from candidate source SCell set3Source as this modification operation
SCell；
Then, candidate target SCell is selected from candidate target SCell set in such a way：Due to candidate target
Cell in SCell set4And Cell5CC4 and CC5 are corresponded respectively to, except the source SCell having determined that（Cell3）Outside, should
UE other 2 serving cell Cell1And Cell2Correspond respectively to CC1 and CC2, it can be seen that in candidate target SCell set
2 candidate target SCell and cell Cell1And Cell2All correspond to different frequencies, therefore base station is from candidate target SCell collection
The Cell of highest priority is selected in conjunction4；
Afterwards, UE is compared in candidate target SCell in base station（Cell4）With source SCell（Cell3）On RSRQ, due to the UE
In Cell3On RSRQ be 18dB, in Cell4On RSRQ be 23dB, i.e. RSRQs of the UE on target candidate SCell be more than should
RSRQs of the UE on the SCell of source, candidate target SCell performance are better than the performance on the SCell of source, therefore by Cell4Configuration
For the SCell of the UE, to replace the original auxiliary serving cell Cell of the UE3。

Power, sorted according to the data carrying capabilities order from big to small of surplus resources.
Step a3：A candidate target SCell is selected from candidate target SCell set, such as, from the candidate after sequence
Highest priority is selected in target SCell set（The data carrying capabilities highest of RSRQ highests or surplus resources）Candidate target
SCell；
Step a4：Base station judges whether the candidate target SCell and source SCell determined before is same cell,
If not same cell, then candidate target SCell is defined as this target SCell for changing operation；Otherwise, then do not enter
Row SCell modification.
Another specific implementation process of step 2 in above-mentioned flow can comprise the steps of b1 ~ b4：
Step b1：Base station determines the source SCell of this SCell modification operations.The source SCell of this SCell modification operations
The SCell of SCell modifications is performed for triggering, i.e. the SCell that A2 event measurement reports are reported；
Step b2：The serving cell that base station configures according to the carrier wave of system and UE is current configures, and determines that this SCell is repaiied
Change the candidate target SCell set of operation.Specific method is：Removed in all available member carriers of system and be already allocated to this
UE CC（PCC can only be included by distributing to UE CC, can also include PCC and SCC）, these remaining member carrier composition times
Target CC is selected to gather, by cell corresponding to candidate target CC set（These cells serving cell current with UE belongs to same

It is defined as the target SCell of this modification operation；Otherwise, then without SCell modification.
Illustrate the detailed process using the triggering SCell modifications of A2 events below by a concrete scene.
The scene is：5 descending carriers of CA system configurations, are designated as CC1, CC2, CC3, CC4 and CC5 respectively.Some UE
Base station n is belonged to, and the UE currently has 3 serving cells, i.e.,：1 PCell and 2 SCell.Wherein：PCell corresponds to CC1,
It is designated as Cell1；2 SCell correspond to CC2 and CC3 respectively, are designated as Cell respectively2And Cell3.Base station n is carried out down for the UE
Row data transfer.Base station n is that A2 measurement events are respectively configured in UE on frequency CC1, CC2 and CC3.
Sometime, base station n receives the A2 event measurement reports from the UE, and the frequency reported is CC2, explanation
Now the UE is in Cell2On channel quality it is poor.Now, UE is in Cell2On average transmission rate be 300bit, in Cell3
On average transmission rate be 500bit, because UE is in Cell2On transmission rate（300bit）<UE is on all SCell
Average transmission rate（（300+500）/2=400bit）, therefore trigger the SCell modification operations performed for the UE.
After triggering performs the SCell modification operations for the UE, base station will trigger the SCell for performing this SCell and changing
（That is Cell2）It is defined as the source SCell of this SCell modification operations.
Base station determines that the candidate target SCell collection of this SCell modification operations merges the Deta bearer according to surplus resources
Cell during ability is gathered candidate target SCell is ranked up.Assuming that network topology is omni cell scene, then for one
For individual base station, the corresponding cell of each CC.Removed in all 5 available member carriers of base station n and be already allocated to the UE
CC（PCC may only be included by distributing to UE CC, it is also possible to which, including PCC and SCC, the CC that the UE is distributed in this scene is
CC1、CC2、CC3）, by the member carrier CC2 corresponding to remaining 2 member carrier CC4 and CC5 and candidate source SCell totally 3
Individual member carrier composition is gathered for candidate target CC, by cell corresponding to this 3 candidate target CC（These cells and UE are current
Serving cell belongs to same base station）It is defined as the candidate target SCell set of this SCell modification operations, the i.e. candidate
Cell is included in target SCell set2、Cell4And Cell5.Cell in gathering for candidate target SCell, considers UE
The average resource occupancy on RSRQ and each cell in this 3 cells, estimates the surplus resources in this 3 cells respectively
Data carrying capabilities, it is assumed that according to estimation result, cell Cell2On the data volume that can carry of surplus resources be 1500bit,
Cell Cell4On the data volume that can carry of surplus resources be 2000bit, cell Cell5On the data that can carry of surplus resources
Measure as 3000bit, therefore ranking results are：Cell5>Cell4>Cell2（That is Cell5Priority be more than Cell4, Cell4It is excellent
First level is more than Cell2）.
Base station selects the candidate target SCell of highest priority from candidate target SCell set（Cell5）.Due to source
SCell（Cell2）With candidate target SCell（Cell5）It is not same cell, therefore by Cell5It is configured to the UE's
SCell, to replace the original auxiliary serving cell Cell of the UE2。

The A6 event measurement reports reported present embodiment describes base station according to UE carry out the flow of SCell modifications, the stream
Journey may include：
Step 1：Base station receives UE A6 measurement events report, and judges whether triggering pin according to the A6 event measurement reports
Operation is changed to the SCell of the UE.
Specifically, base station, which is UE frequencies where each SCell, configures A6 measurement events.Exist if base station receives from UE
A6 event measurement reports on frequency where some SCell, then illustrate that now UE is present on the frequency than current this
The more preferable cell of SCell channel qualities.If the cell in the adjacent area that this measurement of UE reports under the home base station comprising the UE,
Then triggering performs the modification operation for the SCell of the UE；Otherwise, the modification operation for the SCell of the UE is not triggered.
Step 2：This SCell modification operation determinations the source SCell and target SCell that base station is the UE.Specifically, the step
Suddenly 2.1 ~ 2.3 can be comprised the steps of：
Step 2.1：The SCell on frequency that this A6 affair is reported, it is defined as the source of this modification operation
SCell；
Step 2.2：The candidate target SCell set of this modification operation is determined, a step of going forward side by side is ranked up.Preferably,
The embodiments of the invention provide following two sort methods：
Sort method 1：According to UE candidate target SCell set in each cell on RSRQ, according to RSRQ from greatly to
Small order sequence；
Sort method 2：Consider RSRQs of the UE in each cell in candidate target SCell set, and these are small
Average resource occupancy in area, estimate the Deta bearer energy of the surplus resources in each cell in candidate target SCell set
Power, sorted according to the data carrying capabilities order from big to small of surplus resources.
Step 2.3：Gathered according to candidate target SCell, determine the target SCell of this modification operation.If specifically, adopt
It is ranked up with sort method 1, then selects the maximum cells of the RSRQ in candidate target SCell set, repaiied as this SCell
The target SCell changed；It is ranked up according to sort method 2, then selects the number of the surplus resources in candidate target SCell set
According to the cell that bearing capacity is maximum, the target SCell as this SCell modifications.
Step 3：The base station target SCell determined, replaces the source SCell determined.
Illustrate the detailed process using the triggering SCell modifications of A6 events below by a concrete scene.
The scene is：2 descending carriers of CA system configurations, are designated as CC1 and CC2 respectively.Network topology is that three sectors are small
Area's scene, i.e., for a base station, corresponding 3 cells of each CC.Cell corresponding to 2 CC under the n of base station is designated as respectively
Cellij, wherein i expression carrier index, i span is 1 and 2；J represents the sector number under same carrier wave, j value model
Enclose for 1,2 and 3.Some UE belongs to base station n, and the UE currently has 2 serving cells, i.e.,：1 PCell and 1 SCell.Its
In：PCell corresponds to CC1, is Cell11；SCell corresponds to CC2, is Cell21.Base station n carries out downlink data biography for the UE
It is defeated.Base station n is that UE configures A6 measurement events on frequency CC2.
Sometime, base station n receives the A6 event measurement reports from the UE, illustrates that now the UE is in frequency CC2
It is upper the SCell channel quality more preferable cell more current than the UE to be present.Assuming that include base station n in the adjacent area that this measurement of UE reports
Under 2 cell Cell22And Cell23, then modification operation of the triggering for UE execution SCell.
After triggering performs the SCell modification operations for the UE, base station determines that the source SCell of this SCell modifications is tactile
