The mobile device of load.
Base station is public mobile communication base station, is a kind of form of radio station, is referred in certain area of radio coverage
In, radio station is believed by the transceiving that information transmission is carried out between mobile switching center, with mobile telephone terminal.
A kind of method and device for processing carrier aggregation configuration provided in an embodiment of the present invention is based on network as shown in Figure 1
Framework, including MME (Mobility Management Entity, mobile management nodes) 101, SGW (Serving GateWay,
Gateway) 102, eNB (Evolved Node B, evolved NodeB) 103, UE (User Equipment, user equipment)
104.MME101 mainly processes the interaction of signaling between UE and core network, and SGW102 is responsible for the forwarding of signaling and data,
ENB103 is responsible for carrying out signal transacting and resource management, and UE104 is measured and forwarded to wireless signal, and provides the user language

As shown in figure 1, cell when if UE is initially accessed is Cell1, the main plot PCell of UE is Cell1, cell
Cell12, Cell3, Cell4 can be used as secondary cell SCell.
A kind of method for processing carrier aggregation configuration provided in an embodiment of the present invention is entered below for the above-mentioned network architecture
Row explanation.As shown in Fig. 2 being a kind of method flow schematic diagram for processing carrier aggregation configuration provided in an embodiment of the present invention, bag
Include：
Step 201：The measurement report that receiving terminal is reported, according to the measurement report, determines that multiple carrier waves of terminal gather
Close handling process；
Specifically, terminal sends measurement report when measurement report condition is met to base station, and measurement report content includes：
Measurement ID, the measured value of Serving cell, specific measured value include RSRP (Reference Signal Receiving Power,
Reference Signal Received Power) and RSRQ (ReferenceSignalReceivingQuality, Reference Signal Received Quality) etc..
Base station multiple carrier aggregation handling processes of terminal, i.e., same survey are determined according to the measurement report of terminal to report
Comprising multiple carrier aggregation operations in amount report, i.e., multiple carrier aggregation process concurrencies.For example, according to measurement report, determining
Increase secondary cell, delete secondary cell and change three operations of secondary cell and be concurrent.
Step 202：For each carrier aggregation handling process, determine that the carrier aggregation of the carrier aggregation handling process is matched somebody with somebody
Confidence ceases；
Specifically, for example increase secondary cell, delete three operations of secondary cell and modification secondary cell concurrently, then to any of which
Flow, determines carrier aggregation configuration information.Carrier aggregation configuration information can be scheduling carrier wave, including PDCCH (Physical
Downlink Control Channel, Physical Downlink Control Channel) and PDSCH (Physical Downlink Shared
Channel, Physical Downlink Shared Channel) etc..
Step 203：Serial process multiple carrier aggregation configuration information.
Specifically, serial process is carried out to concurrent carrier aggregation flow, i.e., is gathered by default each carrier wave that is arranged in order
Interflow journey.If multiple polymerization carrier configuration information includes increasing secondary carrier, deletes secondary carrier and modification secondary carrier, sequentially hold
Row increases secondary carrier, deletes secondary carrier, the configuration process of modification secondary carrier.
Further, if to the configuration processing failure of increase secondary carrier, the resource for carrying out rrc layer is retracted, and judgement is repaiied
Whether the configuration for changing secondary carrier is related to the configuration for increasing secondary carrier；If so, then deleting the configuration of modification secondary carrier, it is directly entered
Modification secondary carrier configuration failure flow.Further, if to the configuration processing failure of deletion secondary carrier, the auxiliary of failure will be deleted
Carrier wave is used as delete processing.Further, if the configuration failure of modification secondary carrier, after judging the rollback of modification secondary carrier
Whether resource distribution is related to the configuration for deleting secondary carrier；If so, then being reconfigured to modification secondary carrier, RRC is otherwise carried out
The resource of layer retracts.
As shown in figure 3, being a kind of Serving cell configuration diagram of terminal provided in an embodiment of the present invention.Assuming that Cell1
As the main plot PCell301 of UE, and the secondary cell SCell1 302 and SCell2 of Cell2 and Cell3 as UE are added
303., it is necessary to set its scheduling carrier wave for secondary cell SCell, scheduling carrier wave can be this secondary cell, or its
Its cell (PCell or other SCell).Assuming that the scheduling carrier wave of SCell1302 is SCell2 303, the tune of SCell2 303
Degree carrier wave is itself SCell2 303.
Base station receives the measurement report of terminal transmission, and determining needs to increase Cell4 as secondary cell SCell3304,
And its scheduling carrier wave is set for itself, and delete secondary cell SCell2 303.For deleting secondary cell SCell2 303, due to auxiliary
The scheduling carrier wave of cell SCell1 302 is SCell2 303, deletes SCell2 303, then trigger modification secondary cell simultaneously
SCell1 302, it is assumed that modification SCell1 302 scheduling carrier waves are SCell3304.
Now, SCell3 304 increases, and SCell2 303 is deleted, and SCell1 302 changes three process concurrencies, then order
Performing increases secondary cell, deletes secondary cell, the configuration process of modification secondary cell, that is, ensure other SCell when processing a SCell
Can normally use, so as to ensure that UE speed is balanced.
When increasing the configuration failure of secondary cell, first judge to whether there is and increase in the list of modification secondary cell
The related secondary cells of SCell, if it does, can the directly deletion from the waiting list of modification secondary cell, directly carry out RRC
Layer resource is retracted, and the signaling consumption of base station side and UE is not related to.If for example, increase secondary cell SCell3 304 failing, judging
Configuration (modification SCell1302 scheduling carrier waves are SCell3 304) and the increased secondary cell of modification secondary cell SCell1 302
SCell3 304 is relevant, then delete the configuration of modification secondary cell SCell1 302, carries out rrc layer resource rollback.After rollback
The scheduling carrier wave of SCell1 302 is SCell2 303, because concurrent waiting list includes that SCell2 303 deletes configuration, then
Need to recalculate the scheduling carrier wave of SCell1 302, specifically optional scheduling carrier wave is itself SCell1 302.Now
SCell3 304 increases, and SCell2 303 is deleted, and three process concurrencies of modification of SCell1 302 have been optimized to SCell1 302 and have repaiied
Change, SCell2 303 deletes two process concurrencies, so as to reduce frequent replacement operation, improves systematic function.
There is any exception and be all successfully processed as deletion in the configuration for deleting secondary cell, base station is no longer for secondary cell is matched somebody with somebody
Radio Resource is put, abnormality processing flow is reduced.
For change secondary cell configuration failure, then judge change secondary cell configuration whether with deletion secondary cell configuration
It is related；If so, then being reconfigured to modification secondary cell, the resource for otherwise carrying out rrc layer retracts.For example, modification secondary cell
The configuration failure of SCell1 302, will the scheduling carrier wave of SCell1 302 SCell3 304 be revised as by SCell2303 fail,
Because SCell2 303 has been deleted, then need to recalculate the scheduling carrier wave of SCell1 302, specifically optional scheduling carrier wave is
Itself SCell1 302.
The embodiment of the present invention is serially located in the multipaths concurrent processing of terminal to carrier aggregation process concurrency flow
Reason mechanism, reduces frequent replacement operation, improves systematic function；Corresponding fallback mechanism and abnormal protection mechanism are supported, is had
Good business robustness, improves the satisfaction of user.
It should be noted that the embodiment of the present invention also includes that the measurement configuration information and/or bearer management that determine terminal are matched somebody with somebody
Confidence ceases, i.e., carrier aggregation configuration flow can be concurrent with measurement configuration flow and bearer management configuration flow, now for load
At least two configuration informations carry out parallel processing in ripple aggregation configuration information, measurement configuration information, bearer management configuration information.
Further, bearer management configuration includes re-synchronizing configuration information and bearing modification configuration information.Specifically, first
Carrier aggregation configuration information is added in advance re-synchronizes configuration information and bearing modification configuration information.If any of which was configured
Journey fails, then terminate to process other configurations process, and trigger the application for discharging the terminal resource.
As shown in figure 4, the method schematic diagram of the concurrent flow configuration that the present invention is provided, wherein, carrier aggregation is configured and is flowed
Increase secondary cell 4011, deletion secondary cell 4012, the serial execution of the order of modification secondary cell 4013 in journey 401, to carrier aggregation
Flow 4031, bearing modification stream are re-synchronized in configuration flow 401, measurement configuration flow 402, bearer management configuration flow 403
The parallel processing of journey 4032.
The embodiment of the present invention in the multipaths concurrent processing of terminal, to carrier aggregation configuration flow and other process concurrencies
When, parallel processing each flow, it is ensured that each flow processing independence a, flow will not be impacted to another flow extremely,
The coupled relation between each flow is relieved, abnormal operation flow is reduced, Service control surface current journey processing delay is reduced.
When measuring configuration flow and carrier aggregation configuration flow is concurrent, because meeting is same when now each flow is configured
When reconfiguration message is issued to UE, thus measurement procedure and carrier aggregation configuration flow are bound into corresponding flow ID respectively, two
Individual flow ID controls each process state.So as to reduce the coupling of flow, interrelated, each flow ID between flow is reduced
The exception of appearance can also independent process, be independent of each other.
It is concurrent for carrier aggregation configuration flow and bearer management configuration flow, it is all to UE due to re-synchronizing requirements of process
Public resource reconfigured, bearing modification flow can be according to QCI (QOS Class Identifier, service quality rating)
The change of grade and change all of public resource of UE.Therefore by carrier aggregation configuration flow, re-synchronize flow, bearing modification
Flow distributes corresponding flow ID, respectively carrier aggregation configuration flow ID1, bearing modification flow ID2 and re-synchronizes flow
ID3, and to three flow-independent treatment.
Because tri- flows of ID1, ID2, ID3 can all be related to the modification of UE public resources, thus the mistake of any one flow
Lose, can all have influence on other two carrying out of flow.Due to each flow-independent, when re-synchronizing flow and the configuration of bearing modification flow
Cannot know that ID1 is concurrent, i.e., cannot know whether that needs reconfigure the increased public resource because of ID1, if ID1 is concurrent but does not enter
Row configuration, then can cause to reconfigure UE failures.Therefore in advance by carrier aggregation configuration information added to re-synchronize configuration information and
Bearing modification configuration information, will carrier aggregation physical layer resources configuration flow ID4 additions ID2, ID3.If flow ID2 and ID3
Flow includes ID4, then re-synchronize any flow failures of flow ID3 and bearing modification flow ID2, and other concurrent flows all need not
Reprocessing, directly application discharges the resource of UE.
The embodiment of the present invention provides a kind of rrc layer system structure diagram of base station side, as shown in figure 5, including：Measurement pipe
Reason unit 501, carrier aggregation administrative unit 502, cell management unit 503, UE administrative units 504；Wherein cell management unit
503 include radio resource managing unit 5031, and UE administrative units 504 include bearer management unit 5041.Wherein, carrier aggregation pipe
The reason triggering carrier aggregation flow of unit 502, the triggering measurement configuration flow of measuring management unit 501, bearer management unit 5041 is touched
Hair bearer management flow, whether bearer management unit 5041 adds during radio resource managing unit 5031 notifies UE administrative units 504
Loading ripple polymerization process.UE administrative units 504 and carrier aggregation administrative unit 502 are processed concurrent flow.Additionally, carrier wave
Cohesively managed unit carries out modularized processing for base station, cell, the function of terminal, will not be repeated here.
The embodiment of the present invention in the multipaths concurrent processing of terminal, to carrier aggregation flow and during other process concurrencies,
Parallel processing each flow, it is ensured that each flow processing independence a, flow will not be impacted to another flow extremely, releases
Coupled relation between each flow, reduces abnormal operation flow, reduces Service control surface current journey processing delay.
