Description
Technical field
The present invention relates to the communications field, in particular to a kind of method and system of switch multicarrier management measurement.
Background technology
Advanced long-term evolution system (Long Term Evolution Advance, abbreviate LTE-A as) carrier aggregation technology (Carrier Aggregation proposed, abbreviate CA as), it can be UE (the User Equipment with respective capabilities, subscriber equipment) provides bigger bandwidth, and improve the peak rate of UE.Long evolving system (Long Term Evolution, abbreviate LTE as) in, the maximum downstream transmission bandwidth of system's support is 20MHz, and in LTE-A, can be by carrier aggregation with two or more component carrier (component carriers, abbreviating CC as) polymerization gets up to support that greater than 20MHz, maximum is no more than the transmission bandwidth of 100MHz, and Fig. 1 is the schematic diagram according to the carrier aggregation of correlation technique.
The frequency range that component carrier can use LTE to define also can be used the newly-increased specially frequency range as LTE-A.Whether continuous on frequency domain by each component carrier, carrier aggregation can be divided into continuous carrier aggregation and discrete carrier aggregation.By each component carrier whether in identical frequency band, carrier aggregation can be divided into the carrier aggregation of single band (single band) and stride the carrier aggregation of frequency band (over multiple frequency bands), so-called single carrier aggregation is meant all component carriers that participate in carrier aggregation all in same frequency band, and single carrier aggregation can be that continuous carrier aggregation also can be discontinuous carrier aggregation; The carrier aggregation that what is called is striden frequency band is meant that the component carrier that participates in carrier aggregation can be derived from different frequency bands.LTE-A UE with carrier aggregation ability is transceive data on a plurality of component carriers simultaneously, and LTE UE can only be on the component carrier of a compatible LTE transceive data.The coverage that participates in each component carrier of carrier aggregation may be identical, and as shown in Figure 2, the coverage of downlink component carrier CC1 and CC2 is identical; The coverage that participates in each component carrier of carrier aggregation also may be different, and as shown in Figure 3, the coverage of downlink component carrier CC2 is greater than the coverage of downlink component carrier CC1.
In mobile communication system, UE can be in each moving between cells, in order to guarantee business continuance, guarantee quality of service, after the user set up business, UE need measure according to the configuration of serving BS, and satisfied the measurement report of serving BS configuration requirement to the serving BS report.With the LTE system is example, and factor such as the measurement report that serving BS can report according to UE and the load of neighbor cell, service distribution, hardware resource is carried out the mobile management (also can be called switch decision) of connected state; The measurement report that reports according to UE and the resource operating position of homogeneous frequency adjacent area and business load situation carry out Inter-Cell Interference Coordination (Inter-cell Interference Coordination, ICIC).
With the intrasystem example that is measured as of LTE, the detailed process that connected state is measured down is: network side will be measured control messages and send to UE, wherein, measure in the control messages and comprise measuring object (MeasurementObject, be called for short MO) tabulation, MO comprises the LTE frequency that needs are measured, and each frequency is with the unique sign of a MOID (measObjectId, measuring object identifies); Measurement report configuration (ReportConfiguration, be called for short RC) tabulation, the attribute that comprises each measurement report configuration, such as, measurement report is reporting events or periodic report and configuration parameter corresponding, each measurement report disposes with the unique sign of a RCID (reportConfigId, measurement report configuration identifier); Measure sign (Measurement ID is called for short MID) tabulation, MID is the sign of each concrete measurement task, in the MID tabulation, the related MOID of each MID and a RCID, thereby measurement task of unique sign, the measurement configuration information on promptly unique certain frequency of sign.Measure thresholding (s-Measure) in addition in addition, represent the signal quality thresholding of persistent district; Measuring amount configuration (QuantityConfiguration) is used to indicate concrete measuring amount; Measurement clearance configuration (Measurement GapConfiguration) is used for the configuration of alien frequencies, isosystem measurement etc.UE can be known the number of tasks of measurement by the number of MID, the attribute that MO and the RC by the MID correspondence obtains the task of measuring, such as, should how to measure, should how to report etc.
Switching can cause the propagation delay time of user data in handoff procedure, and causes certain data-bag lost; In order to seek suitable switching target small area, need UE to measure and reporting measurement reports in addition, consume the electric weight of UE on the one hand, reporting of measurement report also expended interface-free resources on the other hand; Handoff procedure itself also can cause bigger overhead in addition.Therefore in the LTE system, have only the Serving cell poor signal quality as UE to arrive to a certain degree, UE just can open nearby region measurement, reports the measurement report that satisfies condition, to avoid unnecessary measurement, measurement to report and to switch.This external cause has only when UE just can be subjected to more serious homogeneous-frequency adjacent-domain when the cell edge and disturbs, thereby need the UE measurement and report the strong jamming homogeneous-frequency adjacent-domain to carry out Inter-Cell Interference Coordination, therefore for Inter-Cell Interference Coordination, in the LTE system, also have only Serving cell poor signal quality to arrive to a certain degree as UE, UE just can open homogeneous-frequency adjacent-domain and measure, and reports the measurement report that satisfies condition.In sum, in the LTE system, have only when the signal quality of Serving cell during less than the pre-configured thresholding (S-measure) of network, UE just can start nearby region measurement, reports the measurement report that satisfies condition.
After introducing carrier aggregation technology, in order to satisfy the requirement of carrying peak value speed, need provide bigger bandwidth for UE, UE with carrier aggregation ability can be operated on the individual component carrier of N (N is 5 to the maximum) (frequency), promptly, UE can (working frequency points of these sub-districts is respectively above-mentioned N different component carrier, and these sub-districts are called work sub-district or the Serving cell of UE) enterprising line data transmitting-receiving simultaneously N sub-district.In order to distribute suitable component carrier to UE, the base station need obtain the signal quality of each sub-district on current each component carrier that can carry out carrier aggregation of UE, load in conjunction with each component carrier, service distribution, disturbed condition on the component carrier etc. carries out component carrier management (multicarrier management), selects cell allocation on one or more component carriers that can carry out carrier aggregation to UE.
As Fig. 2 or shown in Figure 3, the component carrier with overlapping coverage that only is positioned under the same base station just can carry out carrier aggregation, if continue to adopt the mechanism of LTE system start-up nearby region measurement, promptly have only when the signal quality of Serving cell and just start nearby region measurement during less than certain thresholding, can not satisfy the demand of component carrier management on the one hand, promptly when the signal quality of Serving cell during greater than thresholding, UE does not start nearby region measurement, thereby cause the base station can't obtain the signal quality of each sub-district on each component carrier that can carry out carrier aggregation, can't carry out the component carrier management; On the other hand, can't satisfy the demand of many Serving cells, promptly when UE is operated on the more than one component carrier, have a plurality of Serving cells, and the mechanism of LTE system start-up nearby region measurement be only applicable to a Serving cell.

S601: the base station is the measurement task of UE configuration component carrier management.
Based on component carrier operating position schematic diagram as shown in Figure 4, the base station is that the measurement task of serving the component carrier management of UE configuration illustrates with S501.
The base station is in the above-mentioned measurement task of configuration, and notice UE switch multicarrier is managed the pre-defined rule configuration information needed of measuring.Below lift the pre-defined rule that the management of two example explanation switch multicarriers is measured, and need to notify the configuration information of UE under the ad hoc rules:
Example one (pre-defined rule 1): the base station is thresholding of each component carrier configuration of UE work, and when arbitrary Serving cell signal quality of UE work during less than the thresholding on the component carrier at this Serving cell place, UE opens the component carrier management and measures.Otherwise when the signal quality of all Serving cells of UE work during greater than the thresholding on the component carrier at Serving cell place separately, UE stops the component carrier management and measures.
According to component carrier operating position schematic diagram shown in Figure 4, the base station is that CC1 and CC2 dispose two thresholdings, S1 and S2 respectively in this example.When signal quality＜S1 of cell1 or the thresholding of cell2＜S2, UE opens the component carrier management and measures; Otherwise when signal quality 〉=S1 of cell1 and the thresholding of cell2 〉=S2, UE stops the component carrier management and measures.
Thresholding S1 on the UE CC1 and the thresholding S2 on the CC2 are notified in the base station in S601.
Example two (pre-defined rule 2): the base station is unified thresholding that is applied to all working component carrier of UE configuration, and when arbitrary Serving cell signal quality of UE work was unified thresholding less than this, UE opened the component carrier management and measures; Otherwise when the signal quality of all Serving cells of UE work was unified thresholding greater than this, UE stopped the component carrier management and measures.
According to component carrier operating position schematic diagram shown in Figure 4, the base station is the unified thresholding S that switch component carrier management of UE configuration is measured in this example.When signal quality＜S of cell1 or the thresholding of cell2＜S, UE opens the component carrier management and measures; Otherwise when signal quality 〉=S of cell1 and the thresholding of cell2 〉=S, UE stops the component carrier management and measures.
Above-mentioned unified thresholding S is notified UE in the base station in S601.
Example three (pre-defined rule 3): the measurement task that the base station is measured for each Serving cell configuration starting/stop component carrier management, when arbitrary Serving cell signal quality of UE work triggered the measurement report of the measurement task that above-mentioned startup component carrier management measures, UE opened the component carrier management and measures; Otherwise when the signal quality of all Serving cells of UE work triggered the above-mentioned measurement report that stops the measurement task that the component carrier management measures, UE stopped the component carrier management and measures.
