Description
Technical field
The present invention relates to the communications field, in particular to a kind of starting method and subscriber equipment of measurement task in multiple carriers.
Background technology
In LTE system under connected state, the detailed process measured is: Survey control message is sent to UE by network side, wherein, this Survey control message comprises other association attributeses measured mark, measuring object, report configuration and measure, and measures mark by measuring object with report that configuration association is got up the complete measurement task of formation one.Measuring object contains measuring object attribute (as carrier frequency, Neighboring Cell List etc.), each carrier frequency only can configure a measuring object, report configuration packet contains report configuration attribute (as event triggers or periodic report, the event definition (A1, A2...) triggered, reports number of times etc.).UE goes to perform measure and assessment according to the measuring object in Survey control message, report configuration, and reports network side according to measurement result generation measurement report.The measurement report that network side reports according to UE, carry out switch decision and Inter-Cell Interference Coordination (Inter-cellInterferenceCoordination, referred to as ICIC), wherein ICIC only carries out for homogeneous-frequency adjacent-domain.
For the measurement task that event triggers, be just considered to meet the measuring object of trigger conditions when the duration that measuring object meets the entry criteria (such as neighboring cell signal quality is better than thresholding) of event is equal to or greater than TTT (TimeToTrigger).After having measuring object to meet the trigger condition of event, reporting measurement reports, to network side, reports the measuring object in report to be sort according to the measuring amount of network settings, optimum above.For ICIC, when the community meeting event entry criteria meet leave condition time, also reporting measurement reports, network side carries out ICIC according to this information, this is distinguished by measuring reportOnleave in configuration, namely when reportOnleave is that TRUE, UE need the reporting measurement reports when community meets the condition of leaving, just the measurement task of event A3 has this characteristic at present.
In Current protocol, the prerequisite of the same frequency that UE startup network side configures, alien frequencies, isosystem measurement is, s-measure (value of a RSRP specified) is configuration not, or the RSRP being configured with s-measure Serving cell simultaneously after the filtration of layer three, (be called s-Serving) lower than s-measure.The object of current configuration s-measure is to reduce the frequency measured and report.If be configured with s-measure, s-Serving is always higher than s-measure simultaneously, and so UE does not start the measurement task of network side configuration, as shown in Figure 1.
For providing higher data rate to mobile subscriber, advanced long-term evolution system (LongTermEvolutionAdvance, be called for short LTE-A) propose carrier aggregation technology (CarrierAggregation, be called for short CA), its objective is that the UE for having respective capabilities provides larger broadband, improving the peak rate of UE.In LTE, the maximum downstream transmission bandwidth of system support is 20MHz, and carrier aggregation the component carrier of two or more (ComponentCarriers is called for short CC) is aggregating support be greater than 20MHz, the maximum transmission bandwidth being no more than 100MHz.Component carrier can use the defined frequency range of LTE, also can use the frequency range for LTE-A increases newly specially.Nervous based on current frequency spectrum resource, continuous print component carrier on frequency domain always can not be had can to distribute to operator and use, therefore whether carrier aggregation is continuous on frequency domain by each component carrier, can divide continuous print carrier aggregation and discrete carrier aggregation.Carrier aggregation by each component carrier whether in identical frequency band, the carrier aggregation of single band (singleband) and the carrier aggregation across frequency band (multiplefrequencybands) can be divided into, so-called single carrier aggregation refers to that all component carriers participating in carrier aggregation are all in same frequency band, and single carrier aggregation can be continuous print carrier aggregation also can be discrete carrier aggregation; The so-called carrier aggregation across frequency band refers to that the component carrier participating in carrier aggregation can be derived from different frequency bands.There is the LTE-AUE of carrier aggregation capacity, can simultaneously transceiving data on multiple component carrier, the UE below related to except special instruction be all this type of UE.In lte-a system, UE to enter after connected state can simultaneously by multiple component carrier (as CC1, CC2) communicate with source base station, base station can be that UE specifies a principal component carrier wave (PrimaryComponentCarrier by explicit configuration or according to protocol conventions, referred to as PCC), other component carrier is called auxiliary component carrier (SecondaryComponentCarrier, referred to as SCC), Serving cell on DLPCC is called main Serving cell (PrimaryCell, referred to as Pcell), Serving cell on DLSCC is called auxiliary serving cell (SecondaryCell, referred to as Scell).NAS information (as information such as ECGI, TAI) is obtained by Pcell, needs to perform RRC process of reconstruction if RLF, UE occur DLPCC.After UE enters connected state from IDLE state access network, the CC of access is PCC.UE is when connected state, and network can complete the transfer process of Pcell by RRC reprovision or switching within cell, or network side carries out specifying Pcell in the process switched at notice UE.
In defined measurement event, the measurement task that partial event triggers needs to be configured to the signal quality of the component carrier of UE as a reference when carrying out measurement event assessment, as event A3 (skew that the signal quality of abutting subdistrict is specified higher than than the signal quality of Serving cell), for this type of common frequency measurement task, with the signal quality of the Serving cell on the component carrier that this frequency has been configured as a reference (i.e. reference cell), namely the signal quality when abutting subdistrict meets the entry criteria of event A3 than the signal quality of corresponding component carrier higher than this abutting subdistrict when specifying Offsets.For this type of different-frequency measure task, can with the signal quality of Pcell as a reference, or the signal quality of the component carrier of specifying as a reference, the signal quality namely when abutting subdistrict meets the entry criteria of event A3 than the signal quality of Serving cell on Pcell or appointment component carrier higher than this abutting subdistrict when specifying Offsets.(signal quality of Serving cell is lower than appointed threshold 1 for event A5, the signal quality of abutting subdistrict is higher than appointed threshold 2), event B2 (, lower than appointed threshold 1, the signal quality of different system abutting subdistrict is higher than appointed threshold 2 for the signal quality of Serving cell) and event A3 are similar.The measurement task that partial event triggers carries out Measuring Time assessment without the need for reference cell, as event A1 (signal quality of Serving cell is higher than appointed threshold), event A2 (signal quality of Serving cell is lower than appointed threshold), event A4 (signal quality of abutting subdistrict is higher than appointed threshold), event B1 (signal quality of different system abutting subdistrict is higher than appointed threshold).Period measurement task is also without the need for reference cell.It should be noted that the startup of the measurement task of event A1 and A2 does not control by s-measure, because event A1 and A2 measures Serving cell, as long as therefore measurement task is configured with, just measuring, until measurement task deletes always.
For the measurement task of event A3, defined two classes at present, the carrier frequency of a class to be the carrier frequency of measuring object be SCC, reference cell is the Scell identical with the carrier frequency of measuring object, is called with A3 event frequently.An other class is the carrier frequency of measuring object is all possible carrier frequency, and comprise the carrier frequency of SCC, reference cell is Pcell, is called A3-PCC.
But inventor finds, the starting method of measurement task in multiple carriers is also uncertain, thus may increase measurement report, waste interface-free resources, and then can not meet consumers' demand.
