As shown in figure 5, SCell may include following steps according to implicit judgement bar triggering SCell deactivation processes are deactivated：
Step 501：PCell is the SCell in across the base station carrier polymerization of UE configurations, and activates the SCell.Wherein, the stream
PCell and SCell in journey are main plot and secondary cell in across the base station carrier polymerization for UE configurations, where PCell
SCell eNB where PCell eNB and SCell are different base stations.
Step 502：SCell carries out the implicit deactivation judgement of the SCell.
SCell home base stations can be to safeguard the packet data inactivity timer (deactivation using the station as SCell each UE
Timer is referred to as sCellDeactivationTimer), when SCell is activated, start or restart corresponding to the SCell
SCellDeactivationTimer, and the scheduling authorization physical down control distributed for SCell ownership UE on the SCell
During channel (Physical Downlink Control Channel, abbreviation PDCCH), restart corresponding
sCellDeactivationTimer。
When SCell is the sCellDeactivationTimer time-out that a UE is configured, then judgement needs to be directed to the UE
SCell is performed to deactivate.
Step 503：SCell eNB where the SCell send SCell triggerings by X2 interface to PCell eNB
SCell deactivates instruction, (asks PCell to set the carrier aggregation state of the SCell to ask to deactivate the SCell
For deactivation status), it is that SCell is implicitly deactivated that UE marks, SCell marks and SCell are carried in the instruction and deactivates reason
It is living.
Step 504：After PCell receives SCell deactivation instructions, the SCell is arranged to deactivation status.Because should
SCell deactivates reason and deactivated to be implicit, and PCell can need not send MAC CE and notify the UE to deactivate the SCell.
Step 505：PCell eNB are deactivated by X2 interface transmission secondary cell to be confirmed, UE marks are carried in the message, are somebody's turn to do
SCell marks etc..
Step 506：After SCell eNB receive secondary cell deactivation confirmation, remove all RBs of the UE on the SCell
Relevant information.
By above description as can be seen that when the UE is not scheduled for a long time, UE side bases are in SCell packet data inactivity timers
SCell deactivation is carried out, UE no longer monitors the SCell after SCell is deactivated.Now, SCell judges whether the UE goes
It has activated the SCell.If it is determined that the UE has deactivated the SCell, then SCell synchronously deactivates the SCell, it is impossible to after
Continue the data that the UE is sent on the SCell., it is necessary to lead in time after SCell eNB judge that the UE has deactivated the SCell
Know PCell eNB, PCell eNB are no longer in the SCell transmitting datas afterwards.
As shown in fig. 6, the process that SCell triggers SCell deactivations according to cell load may include following steps：
Step 601：PCell is the SCell in across the base station carrier polymerization of UE configurations, and activates the SCell.Wherein, the stream
PCell and SCell in journey are main plot and secondary cell in across the base station carrier polymerization for UE configurations, where PCell
SCell eNB where PCell eNB and SCell are different base stations.
Step 602：SCell periodically carries out load balancing judgement.After the cell load is higher than setting thresholding, then really
The fixed cell needs to trigger load balancing.
Step 603：Scell determines load balancing targeted customer, is performed for these load balancing targeted customer in station
SCell activation, SCell shares the cell load and realizes load balancing in the station by activating these UE.Wherein, should
SCell can select load balancing targeted customer according to following condition：Using the SCell as the PCell of carrier aggregation, and it is configured
But SCell UE not yet in activation station.
For example, the base station where cell 1 is eNB1, cell 2 and cell 3 belong to same base station eNB 2.In cell 1
UEa is configured with across base station carrier polymerization, wherein, cell 1 is the PCell in across the base station carrier polymerization, and cell 2 is should be across base station
SCell in carrier aggregation.UEb in cell 2 is configured with station intercarrier polymerization, wherein, cell 2 is in the station intercarrier polymerization
PCell, cell 3 is the SCell in the polymerization of station intercarrier and is not yet activated.Cell 2 is as in across base station carrier polymerization
SCell carry out cell load detection, when detecting that cell load is more than the load balancing thresholding of setting, perform following load
The selection course of equalization target user：
In using cell 2 as the PCell of station intercarrier polymerization UE, if SCell in configured station be present but not yet swash
It serves somebody right station in SCell UE, if in the presence of, by the UE selection be load balancing targeted customer.For example the UEb in this example is chosen
It is selected as load balancing targeted customer.
Further, if in selecting the targeted customer of load balancing using aforesaid way and these users being stood
After SCell activation, the load of the cell is less than or equal to setting thresholding, then terminates this load balancing flow；If using upper
The mode of stating selects the targeted customer of load balancing and after the interior SCell activation that to these users stand, the load of the cell is still
More than setting thresholding, then step 604 is performed.
Further, if using the load balancing targeted customer number that aforesaid way is selected as 0, step 604 is performed.
Step 604：SCell selections using this cell as across base station carrier polymerization in SCell UE be used as load balancing
Targeted customer.
Step 605：SCell sends SCell by X2 interface to the PCell attributive eNBs of these load balancing targeted customer
Instruction is deactivated, request is no longer using this cell as SCell between station.In the instruction message carry UE mark, the SCell mark and
It is load balancing that SCell, which deactivates reason,.
Step 606：After PCell receives secondary cell deactivation instruction, by being somebody's turn to do in corresponding UE across base station carrier polymerization
SCell is arranged to deactivation status, and sends MAC CE and notify corresponding UE to deactivate the SCell.
Step 607：PCell eNB are sent secondary cell and deactivated by X2 interface to be confirmed, UE marks are carried in the confirmation message
Knowledge, SCell marks etc..
Step 608：After SCell eNB receive secondary cell deactivation confirmation, remove all RBs of the UE on the SCell
Relevant information.
By above description as can be seen that in order to realize across base station carrier polymerization, X2 interface chain of command and X2 interface user
Face needs to interact many information/datas, larger across the cost that eNB carrier aggregation needs are paid, if SCell load is
Very high, in order to reduce load, SCell eNB can ask the deactivation of the SCell to PCell eNB.
