Embodiment
The technical scheme providing in order more clearly to set forth the embodiment of the present invention, the following knowledge of paper:
(1) measurement mechanism of LTE system
In LTE system, base station is by RRC (Radio Resource Control, Radio Resource control) signaling sends measurement configuration information to UE, UE (for example measures according to the content of this measurement configuration information, common frequency measurement, different-frequency measure, different commercial measurement etc.), then measurement result is reported to network side.
Concrete, what network side measured that configuration used is RRC connection reprovision process, and the institutional framework of measurement configuration information comprises:
A) measuring object (measurement object): take frequency as base unit, each measuring object being configured is an independent frequency, has independent measuring object sign (ID).
B) report configuration (report configuration): according to triggering type, be divided into Event triggered and report with the cycle and trigger and report, each reports configuration to have independent ID.Wherein, the reporting the some event threshold values of configuration meeting dispensing and meet duration (Time to Trigger) of trigger condition of Event triggered type, the object that reports configuration meeting dispensing periodic triggers of periodic triggers type, for example, report CGI (Global Cell ID, Cell Global Identity) etc.
LTE is intrasystem at present has five with frequency/different-frequency measure event one, comprising:
Event A1 (Serving becomes better than threshold, Serving cell channel quality is greater than thresholding)
Event A2 (Serving becomes worse than threshold, Serving cell channel quality is less than thresholding)
Event A3 (Neighbour becomes offset better than serving, adjacent cell channel quality is better than Serving cell channel quality)
Event A4 (Neighbour becomes better than threshold, adjacent cell channel quality is greater than thresholding)
Event A5 (Serving becomes worse than threshold 1and neighbour becomes better than threshold2, Serving cell channel quality is less than thresholding 1, adjacent cell channel quality is greater than thresholding 2 simultaneously)
C) measure sign (measurement ID): independent ID, can connect a measuring object simultaneously and report configuration.If reached, open the thresholding of measuring, UE can have or not to judge whether to carry out this kind of measurement according to what measure sign.
D) other parameters: also may comprise measuring amount configuration, measure other parameters such as opening thresholding and speed state parameter.
It should be noted that to measure to have reported three kinds of triggering modes, be respectively: Event triggered reports, periodic report, Event triggered periodic report.These three kinds of modes can be according to reporting the combination of various parameters in configuration to distinguish.
(2) measure the configuration that starts thresholding
UE in LTE system is operated on single carrier, the measurement of its mobility frequency (except A4 event) is all relevant with current service cell, network side need to be measured startup thresholding (s-measure) for UE configures one, when the channel quality of Serving cell is during lower than this s-measure value, start the measurement of all configurations.
Particularly, network side connects measurement configuration IE (the Information Elements in reallocation message at RRC, information element) the s-measure value of configuration pin to current service cell in, as shown in Figure 3, it should be noted that, in the configuration of s-measure parameter value, need to be relevant with the factors such as RRM algorithm of noise circumstance, coverage and the network side of region, current service cell.
(3) Pcell in LTE-A system (primary cell, main Serving cell) and Scell (secondary cell, auxiliary serving cell)
In LTE-A system, UE can be aggregated in simultaneously and on a plurality of carrier waves, carry out signaling scheduling and business transmission, the angle of distributing from resource, at present by the configurable limit of some ascending resources on certain up-link carrier, and definition PCC (primary component carrier, main carrier) concept, wherein, this ascending resource comprises CQI (Channel Quality Indicator, channel-quality feedback), DSR (Dedicated Scheduling Request, specific schedule request), ascending HARQ (Hybrid Auto Repeat request, mixed automatic retransfer request) feeding back ACK (Acknowledge Character, acknowledge character)/NACK (Negative Acknowledgment, negative acknowledge character) etc., after definition main carrier, the restriction in above-mentioned three kinds of ascending resources configuration can be bundled on main carrier.
In addition, in a plurality of carrier waves of UE polymerization, the carrier wave outside main carrier is SCC (secondary component carrier, auxiliary carrier wave), main carrier choose be UE level other, do not require that all UE in LTE-A system are certain to use identical main carrier.It should be noted that the up-downgoing carrier wave that forms main carrier need to meet the corresponding relation of indicating in system information SIB2.
Further, in LTE system, measure the concept that has related to serving cell, in carrier aggregation system, UE can work a plurality of communities of polymerization simultaneously.Current about defined the concept of main Serving cell (Pcell) and auxiliary serving cell (Scell) in the discussion of measuring for a plurality of cell of UE polymerization, corresponding respectively UE works as main carrier (PCC) community and auxiliary carrier wave (SCC) community of pre-polymerization.
(4) measurement in carrier aggregation system
A) CC for UE configuration (comprise activation with unactivated) for each, network side all can be for it configures A1 event and A2 event, and as shown in Figure 4, community 3 is Pcell, community 1 and 2 is Scell, and network side is F1 frequency configuration A1 thing and A2 event.
B) CC for UE configuration (comprise activation with unactivated) for each, network side can be all frequency configuration A3 (with the frequency A3) event at its place, the serving cell (Serving cell) of this A3 event is for configuring the Scell on this frequency to UE, neighbor cell (adjacent cell) can be other any one cell on this frequency, as shown in Figure 4, network side is F2 frequency configuration A3 affair, and serving cell is community 2.
C) do not adopt the event with frequency A5.
D) for any frequency, network side can configure A3/A5 event for it, the serving cell of this A3/A5 event is the current Pcell of UE, neighbor cell can be any cell on this frequency, as shown in Figure 4, for the frequency F4 not configuring, network side configuration A3/A5 affair, serving cell is Pcell community 3.
In prior art, after having introduced carrier aggregation characteristic in LTE-A system, base station is managed except normal mobility RRM, also need to consider QoS (Quality of Service, the service quality) demand of UE, for example, traffic carrying capacity increase need to increase carrier wave newly, and the QoS demand of this UE and the UE signal quality when pre-polymerization work community does not have direct relation, if still adopt the measurement startup/shutdown mechanism of LTE system, can have influence on user's experience.For the problems referred to above, the embodiment of the present invention provides a kind of method and apparatus of measuring control, the execution that QoS demand is measured and s-measure mechanism are independent of one another, in UE power saving, have better served the execution of QoS demand measurement and have measured the configuration that starts thresholding.

The embodiment of the present invention two provides a kind of method of measuring control, as shown in Figure 6, comprises the following steps:
Step 601, user equipment (UE) obtains the corresponding informance of measuring ID and the measurement of QoS demand.
Step 602, described UE measures according to the corresponding informance of described measurement ID and the measurement of described QoS demand.
In the embodiment of the present invention, described UE measures according to the corresponding informance of described measurement ID and the measurement of described QoS demand, comprising:
When Serving cell quality higher than s-measure or Serving cell quality during lower than s-measure (regardless of the signal quality of current service cell, described UE need not be with reference to the signal quality of current service cell), described UE measures and always measures the QoS demand on frequency corresponding to described measurement ID.
In addition, described UE measures according to the corresponding informance of described measurement ID and the measurement of described QoS demand, also comprises:
When Serving cell quality is during higher than s-measure, described UE judges that on the frequency that described measurement ID is corresponding, whether having configured QoS demand measures;
If configure QoS demand, do not measure, described UE stops on the frequency that described measurement ID is corresponding and measures;

The technical scheme providing in order more clearly to set forth the embodiment of the present invention, the method for this measurement being controlled below in conjunction with specific embodiment is discussed in detail.Wherein, the embodiment of the present invention is applicable to carrier aggregation system.In embodiments of the present invention, the Serving cell quality of reference can be the quality of Pcell; The Serving cell quality of reference can be also the Scell quality on this frequency; Explanation no longer in detail in the embodiment of the present invention.
The embodiment of the present invention three provides a kind of method of measuring control, as shown in Figure 7, comprises the following steps:
Step 701, network equipment is determined the information that QoS demand is measured.
In the embodiment of the present invention, consider the QoS demand of UE, network equipment can be determined the information that QoS demand is measured.For example, when the traffic carrying capacity increase of UE causes increasing carrier wave newly, network equipment can be determined the information that QoS demand is measured, if the carrier aggregation subdistrict of current UE is community 1 and community 2, because the traffic carrying capacity of this UE increases, this community 1 and community 2 cannot meet the traffic needs of this UE, now need for this UE polymerization Xin community (for example, community 3), network equipment determines that the QoS demand that is measured as of Gai Xin community measures.
Step 702, network equipment is that QoS demand is measured allocating and measuring ID.
Concrete, for distinguishing QoS demand, measure and RRM measurement, can measure configuration for QoS demand and measure different measurement ID from RRM.For example, when measurement ID is A, represent that the corresponding RRM that is measured as measures; When measurement ID is B, represent the corresponding QoS demand that is measured as measurement, now, when needs are measured allocating and measuring ID for QoS demand, network equipment need to be configured to B by measurement ID.
Step 703, network equipment obtains measurement configuration information according to this measurement ID, and sends this measurement configuration information to UE.
Concrete, this network equipment can send measurement configuration information to UE by RRC signaling, also can to UE, send measurement configuration information by other signalings, take and describe to UE transmission measurement configuration information as example by RRC signaling in the embodiment of the present invention.
When having determined, measure ID and measuring object, report after the corresponding relation between configuration, network equipment is when sending measurement configuration information by RRC signaling to UE, need to carry this measurement ID and measuring object, report the corresponding relation between configuration, and measured accordingly according to this corresponding relation by UE, this process will repeat in detail in subsequent step.
It should be noted that in the embodiment of the present invention, when sending measurement configuration information to UE, it is the measurement ID measuring for QoS demand that network equipment also needs to indicate which measurement ID of UE, and this measures ID and s-measure mechanism is irrelevant.
In the embodiment of the present invention, for distinguishing QoS demand is measured and RRM measurement, and which measurement ID to be that the measurement ID measuring for QoS demand notifies to UE by, the processing mode that can adopt includes but not limited to:
(1) by dividing the span of different measurement ID, come distinguishing QoS demand to measure and RRM measures, for example, by uses, measure ID1-measurement ID4 and represent that QoS demand measures, and by use, measure ID5-measurement ID8 and represent that RRM measures.
Can find out, by dividing the span of different measurement ID, coming distinguishing QoS demand to measure and during RRM measurement, when measuring allocating and measuring ID for QoS demand, the span that need to measure ID according to this to measure allocating and measuring ID for QoS demand, for example, when measuring allocating and measuring ID for QoS demand, need allocating and measuring ID1-to measure the measurement ID within the scope of ID4.
(2) by measuring the mode of ID list, come the measurement of distinguishing QoS demand and RRM to measure, for example, for measuring the measurement ID showing in ID list, represent the measurement of QoS demand, for measuring the measurement ID that there is no demonstration in ID list, represent that RRM measures; Again for example, for measuring the measurement ID showing in ID list, expression RRM measures, and for measuring the measurement ID that there is no demonstration in ID list, represents the measurement of QoS demand.
Can find out, when coming distinguishing QoS demand to measure by the mode of measurement ID list and RRM measures, when measuring allocating and measuring ID for QoS demand, need to measure ID list according to this to measure measurement ID corresponding to configuration for QoS demand, for example, when the measurement ID showing in measuring ID list represents that QoS demand is measured, needing the measurement ID showing in allocating and measuring ID list is the measurement ID that QoS demand is measured.
(3) for each measures an ID expansion bit (bit), and come distinguishing QoS demand to measure and RRM measurement with this bit.Wherein, whether be QoS demand measure to this bit if can be used to indicate this measurement ID.
Certainly, in actual applications, can also come by other means distinguishing QoS demand to measure and RRM measurement, and which measurement ID to be that the measurement ID measuring for QoS demand notifies to UE by, in the embodiment of the present invention, repeat no longer in detail.
Step 704, UE measures according to the measurement ID in this measurement configuration information, and when measuring report condition corresponding to ID and meet reporting measurement result.
Concrete, for the measurement ID relevant to s-measure mechanism, while measuring ID and be the measurement ID that corresponding RRM measures, employing s-measure mechanism is measured, when Serving cell quality is during higher than s-measure, stop measurement corresponding to this measurement ID, if when not configuring QoS demand on frequency corresponding to this measurement ID and measuring, UE stops the measurement on this measurements ID correspondence frequency; If when having configured QoS demand on frequency corresponding to this measurement ID and measuring, UE does not stop the measurement on this frequency, but to RRM, measurement does not report, and only to QoS demand, measurement reports.
For with the irrelevant measurement ID of s-measure mechanism, while measuring ID and be the measurement ID that corresponding QoS demand measures, signal quality regardless of current service cell, UE measures for these measurement that ID is corresponding and reports and always carries out, the frequency that this measurement ID is corresponding always needs to measure, and when measuring report condition corresponding to ID and meet to network equipment reporting measurement result.
It should be noted that in order to determine whether be the measurement ID that for QoS demand measure, UE, when obtaining measurement configuration information, need to judge accordingly according to the measurement ID in this measurement configuration information if measuring ID.
Concrete, (1), when network equipment is by dividing the span of different measurement ID and come distinguishing QoS demand to measure and RRM measuring, the span that UE can measure the measurement ID that ID is positioned at according to this judges whether this measurement ID is the measurement ID for the measurement of QoS demand.
(2), when network equipment is by measuring the mode of ID list and come distinguishing QoS demand to measure and RRM measuring, whether UE can measure ID according to this and be arranged in and measure ID list and judge whether this measurement ID is the measurement ID for the measurement of QoS demand.
(3) when network equipment is each, measure a bit of ID expansion, and come distinguishing QoS demand to measure and during RRM measurement, the expansion bit that UE can measure ID according to this judges whether this measurement ID is the measurement ID for the measurement of QoS demand with this bit.
In order further to set forth the technical scheme that the embodiment of the present invention provides, the method for this measurement being controlled below in conjunction with several concrete application scenarioss is discussed in detail.

The special span of dividing a measurement ID of network equipment is measured to QoS demand, and define QoS demand and measure the maximum use and measure ID parameter, for example, it can be maxCellAddMeasId (this maxCellAddMeasId can be 4) that this maximum is measured ID parameter, now, measurement ID from 1 to maxCellAddMeasId is allocated to QoS demand and measures, when UE receives measurement configuration information, if know that the span of measuring ID is between 1 to maxCellAddMeasId time, this measurement ID is the measurement ID measuring for QoS demand, irrelevant with s-measure mechanism.
Further, for maxCellAddMeasId, to the RRM that is measured as of maxMeasId, measure above.
In the embodiment of the present invention, the value of this maxCellAddMeasId can send to UE by the mode of RRC signaling, also can in agreement, limit the value of this maxCellAddMeasId, certainly, can also by other means the value of maxCellAddMeasId be notified to UE, in the embodiment of the present invention, repeat no longer in detail.
