Abstract
The embodiment of the invention discloses a realization method and a device for MDT (mobile data terminal) measurement. The technical scheme disclosed by the embodiment can distinguish MDT measurement from RRM (radio resource management) measurement so that user equipment UE can use different strategies, measuring precision demands and reporting requirements on different types of measurements.
Description
Technical field
The present invention relates to communication technical field, implementation method and equipment that particularly a kind of MDT measures.
Background technology
In following mobile communication system, wish, by introducing the mechanism of network self-organization, to reduce the artificial participation of the network planning and Operation and Maintenance, by network based statistic Automatic Optimal parameter, reduce construction and the operation cost of network.In order to reduce the O&M cost of network, hope can be taked network configuration UE report method, reduces the work of artificial drive test.On the other hand, also wish to obtain the wireless measurement information in the region that common drive test cannot arrive.
Current LTE (Long Term Evolution, Long Term Evolution) in, at R10, set up the project and determined MDT (Minimization of drive-tests, minimum road test) adopt the framework of chain of command (control plane), the benefit of this framework is exactly that base station can be controlled subscriber equipment (User Equipment, UE) accurately.The configuration and UE the reporting to network that adopt chain of command framework need to use RRC (Radio Resource Control, Radio Resource is controlled) signaling bear network to carry out UE.
1, the measurement in LTE configures and reports mechanism
In LTE system, base station sends measurement configuration information by RRC signaling to UE, and UE measures (with frequency, alien frequencies, different technology) according to the content of measurement configuration information, then measurement result is reported to network.
Wherein, what network measured that configuration used is that RRC connects reconfiguration course, the theing contents are as follows of measurement configuration information:
(1) measuring object (measurement object): take frequency as base unit, each measuring object being configured is an independent frequency, has independent measuring object sign (Identity, ID).
(2) 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.The threshold value that reports the some events of configuration meeting dispensing of Event triggered type and the duration (Time to Trigger) that meets trigger condition, the object that reports configuration meeting dispensing periodic triggers of periodic triggers type, for example, report CGI (CellGlobal Identity, global unique cell identification).
LTE is intrasystem at present has five with frequency/different-frequency measure event one, comprising:
Event A1: Serving cell channel quality is greater than thresholding;
Event A2: Serving cell channel quality is less than thresholding;
Event A3: adjacent cell channel quality is better than Serving cell channel quality;
Event A4: adjacent cell channel quality is greater than thresholding;
Event A5: Serving cell channel quality is less than thresholding 1, adjacent cell channel quality is greater than thresholding 2 simultaneously.
The intrasystem different commercial measurement event one of LTE has two kinds, comprising:
Event B1: different technology adjacent cell channel quality is greater than thresholding;
Event B2: Serving cell channel quality is less than thresholding 1, different technology adjacent cell channel quality is greater than thresholding 2 simultaneously.
(3) measure sign (measId): independent ID, connects a measuring object and one and report configuration.If reached, open the thresholding of measuring, UE can judge whether to carry out this kind of measurement according to measuring having or not of sign.
(4) other parameters: also may comprise measuring amount configuration, measure other parameters such as opening thresholding and speed state parameter.
UE is (serving cell) acceptance service in Serving cell, if Serving cell signal quality is fine, does not need to carry out any type of measurement.When Serving cell signal quality drops to a certain degree, reach while opening the thresholding of measuring, UE will independently start all measurements with frequency, alien frequencies, different technology according to the measurement sign of preserving.
Measure completely and carry out according to the indication of measuring sign.Each measurement sign can connect a measuring object sign simultaneously and report configuration identifier with one, and the measuring object that is not connected to measurement sign identifies and reports configuration identifier can not carry out any type of measurement.Concrete measurement configuration organizes schematic diagram as shown in Figure 1.
Measurement reports by criterion classification can be divided into three kinds: once reporting of Event triggered, periodically reports and Event triggered periodic report.Which kind of UE adopts report mode to determine when measuring configuration distributing, is included in and reports in configuration, by deploy content and form, determines.
Measuring reporting message for every only can report to measure the corresponding content of sign, under a frequency, meet the relevant community (reporting at most maxCellReport is 8 communities) that reports configuration, measuring reporting message content has: measure sign, Reference Signal Received Power in this community (Reference SignalReceived Power, RSRP) (the Reference SignalReceived Quality of the Reference Signal Received Quality in He Zhe community, the physical-layer cell ID of the adjacent cell RSRQ), satisfying condition etc.
2, UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system) measures configuration and reports mechanism:
Different from LTE is, in each measurement sign of UMTS, can fix the corresponding explicit measuring object issuing and report configuration, if need to revise, re-issue a complete set of content, can not only for the measuring object of measuring sign connection, carry out again associated modification with reporting configuration ID.
Measuring type has seven kinds, is respectively: Intra-frequency, Inter-frequency, Inter-RAT, Traffic volume, Quality, UE internal and UE positioning.
In UMTS, defined and located relevant measurement type UE positioning measurement, the located in connection comprising reports content, can be used by MDT measurement, and LTE does not have the detailed locating information of RRC signaling support to report.
3, the existing measuring amount of MDT:
The thought of MDT is to allow UE report relevant metrical information, or corresponding failed turkey is recorded to then report and get on.When recording metrical information and turkey, UE also needs the time at this moment to preserve, and then carries up together, is used for auxiliary network to do the network optimization.
Several MDT measuring amount of having passed through are at present:
(1) Periodical downlink pilot measurements (cycle descending pilot frequency is measured)
(2) Serving Cell becomes worse than threshold (it is poorer than setting thresholding that service district becomes)
(3) Transmit power headroom becomes less than threshold (it is poorer than setting thresholding that PHR becomes)
(4) Random access failure (random access failure)
(5) Paging Channel Failure (paging channel takes defeat)
(6) Broadcast Channel failure (broadcast channel takes defeat)
(7) Radio link failure report (Radio Link Failure report)
In these measuring amount, having some is to trigger that to have some are Event triggered the cycle.
4, MDT measures configuration needs:
Existing RRM (Radio Resource Management, RRM) measure only for connection status, can initiate to report immediately to the UE Event triggered under connected state or cycle triggering, once and Connection Release, UE can not preserve any configuration information for mobility measurements, and the measurement configuration that more can not carry out sending according to connected state is measured and reports.But MDT measures and requires can carry out and reservation record measurement result (logging) in idle condition.
In realizing process of the present invention, inventor finds that prior art at least exists following problem:
MDT measures the multiplexing existing RRM measurement mechanism of can trying one's best, if but use identical mechanism, can not make UE distinguish MDT and RRM measurement configuration, and the partial content in existing RRM measurement is for some redundancy of MDT measurement.

(2) the Serving cell sign that MDT measures, Serving cell identify corresponding MDT measure for current service cell and/or adjacent cell.
Wherein, adjacent cell specifically comprises the co-frequency neighbor cell of current service cell, and/or iso-frequency adjacent community, and/or different technology adjacent cell.
(3) default information, has stipulated in agreement that once measuring object be the measuring object content that default information UE should be used, and can by network side and UE, be arranged by this kind of mode, reduces space interface signaling size.
When MDT measurement is specially the MDT measurement of UMTS system, in the configuration information that the MDT that the network equipment that subscriber equipment receives sends measures, included MDT measures corresponding measuring object information, specifically comprises following two kinds of situations:
(1) MDT measure for current service cell information.
(2) MDT measure institute for current service cell and/or the corresponding MDT measurement of adjacent cell type information.
On the other hand, MDT included in the configuration information that the MDT that the network equipment that subscriber equipment receives sends measures measures the corresponding configuration information that reports, and is specially:
Network equipment adds the new configuration messages element that reports, wherein comprise MDT measure in the parameters information of required measurement, and the new configuration messages element that reports is sent to subscriber equipment; Or,

According to above-mentioned configuration information, subscriber equipment, by the MDT metrical information receiving and other metrical informations, as RRM metrical information is distinguished mutually, thereby completes corresponding MDT measuring process.
Compared with prior art, the present invention has the following advantages:
The technical scheme proposing by the application embodiment of the present invention, the in the situation that of multiplexing existing RRM measurement mechanism and resource, in measuring configuration, RRM is measured with MDT measurement and distinguished, make UE apply different strategies, certainty of measurement demand and to report requirement different measurements.
Below, in conjunction with concrete application scenarios, the technical scheme that the embodiment of the present invention is proposed is elaborated.
Existing RRM mobility measurements mechanism, comprises that arranging one measures sign (measId), connects a measuring object and reports configuration with corresponding one.
Not yet there is at present concrete grammar to relate to MDT and measure configuration mode and structure, below by three kinds of methods explanation MDT, measure the difference that multiplexing RRM measures, be convenient to UE and distinguish, further apply different measurements and reporting policy.
Method one, by measurement, identify and distinguish.
In the prior art, the measurement comprising in LTE identifies maximum 32, maximum 16 of the measurement signs that UMTS comprises.So, for MDT is measured with other measurements and distinguished, can realize by following two kinds of modes:
1, utilize existing measurement sign, mark off the scope of MDT special use:
Take LTE system as example, at existing 32, measure in sign, can stipulate that latter 8 are measured for MDT, other for other measurements or temporarily default, made other purposes.Wherein, measure sign and the division in all measurements signs is example for convenience of explanation a kind of and that propose for MDT measurements for 8, the concrete measurement of selecting to measure for MDT identifies quantity and position can't affect protection scope of the present invention.
In such cases, network is used these to be specifically designed to measurements sign that MDT measures and is configured, and UE receives and measures after configuration, can be easily according to measuring tag slot, which separate is the measurement configuration of MDT special use.
Need to further be pointed out that; above-mentioned explanation is to take LTE system to describe as example; in other system, also can apply such thinking; in the existing measurement sign of this system, determine that one or more measurement signs are for MDT measurement, the variation of concrete system type can't affect protection scope of the present invention.
2, sign number is measured in expansion, and expansion is only measured for MDT:
Take UMTS system as example, the present measurement sign of UMTS only has 16, if mark wherein a part of for LTE or other purposes, may cause RRM to measure sign not enough, can expand existing measurement sign number, from present 4bit (16), extend to 5bit (32), and whole in or a part of MDT measurement special use in the measurement of regulation expansion sign.
Wherein, the concrete measurement sign quantity expanding is example for convenience of explanation a kind of and that propose, and concrete measurement sign quantity and the position measured for MDT selected can't affect protection scope of the present invention.
Need to further be pointed out that; above-mentioned explanation is to take UMTS system to describe as example; in other system, also can apply such thinking; on the existing measurement sign of this system basis, expand for MDT and measure object, the variation of concrete system type can't affect protection scope of the present invention.
Method two, use measuring object are distinguished:
Measuring object be take frequency as unit in existing LTE system, each frequency configuration measuring object parameter separately, and possible black and white lists etc.; Mobility measurements object is divided into frequency/different frequency/different technology in existing UMTS system, and the alien-frequency district of a plurality of frequencies can be configured in a measuring object.
MDT measures mainly for current service cell and possible adjacent cell, carries out periodically or the measurement collection of Event triggered, and measuring object can multiplexing existing structure or added new MDT measuring object.
For the MDT of LTE, measure, measuring object reality is only current area and possible adjacent cell, can:
(1) measuring object being set is only current service frequency, optionally comprises the alien frequencies frequency that adjacent cell may exist;
(2) for MDT arranges measuring object, be Serving cell and adjacent cell around separately, adjacent cell may comprise with frequency/iso-frequency adjacent community and different technology adjacent cell;
(3) for MDT, measure measuring object is not set, or an empty measuring object (NULL) is set, the object that UE is defaulted as MDT measurement is current service cell, optionally comprises adjacent cell around.
On the other hand, for UMTS system, because existing mobility measurements has been divided into measurement types such as frequency/different frequency/different technology, for MDT, measure, can:
(1) measuring object is only made as to Serving cell, uses existing common frequency measurement type;
(2) adding independent MDT and measure type, is Serving cell and possible surrounding's adjacent cell to the type allocating and measuring object.Wherein Serving cell can adopt the default configuration of acquiescence mode, does not appear in explicit configuration, and adjacent cell may comprise with frequency/alien frequencies or different technique district.
For example, in Measurement type, add the type of " UE MDT measurement ", list the list of MDT measuring object, may comprise the frequency at the place, adjacent cell ，Ge community that Serving cell (optional)/needs are measured, cell information etc.By this explicit measuring object, configure, can distinguish MDT and measure and common mobility measurements.
Measurement Control the content in UMTS:
Add a new measurement type UE MDT measurement, relevant information is specifically as shown in table 1:

Method three, use report configuration to distinguish:
Existing LTE report configuration is divided into EUTRAN and InterRAT two classes: ReportConfigEUTRA, and ReportConfigInterRAT, measures for MDT, can:
1, special-purpose reporting of parallel interpolation configures IE (information elements, message element), such as ReportConfigMDT, defines brand-new all MDT measurement event in this IE;
For example:
New interpolation event eventC1-C7 (only defined now 7, follow-up have new events definition can also add other event), corresponding MDT 7 in measuring amount, in each measurement event, add the required parameter configuration of this event.
ReportConfigMDT::＝ SEQUENCE{
eventId CHOICE{
eventC1 SEQUENCE{
[C1 parameter configuration]
}，
eventC2 SEQUENCE{
[C2 parameter configuration]
}，
[other MDT measurement event ...]
}
Other MDT measure desired parameters]
}
Wherein eventC1 may measure for cycle descending pilot frequency, and C1 parameter configuration may comprise periodical timer Periodic timer, measure logging number The number of logging etc.;
Wherein eventC2 may be for Serving cell quality be lower than threshold thresholding, and C2 parameter configuration may comprise that in threshold T hreshold, the long Measurement logging of measurement logging window window, window, logging records frequency in sampling Measurement logging interval etc.
Other event the like.
2, multiplexing existing ReportConfigEUTRA, just adds measurement event and its parameter configuration.
The eventA2 of LTE of take is example:
In existing LTE RRC agreement, having defined A2 event is:
Event A2: Serving cell channel quality is less than thresholding;
For MDT, measure, be similarly Serving cell quality lower than threshold thresholding, the in the situation that of multiplexing original eventA2 event, may measure the threshold value different from MDT measure setup to RRM, can also increase the required parameter of MDT newly, such as measuring logging in the long Measurement logging of logging window window, window, record the contents such as frequency in sampling Measurement logging interval.
The position of newly-increased parameter may be the expansion for event A2, the parameter that the expansion " eventA2-v9x0 " of only adding after the extension marker expansion sign " ... " of closelying follow after several measurement event for A2 is comprised to new interpolation; Or the expansion to other report configuration of high one-level, adds this new argument in " ReportConfigEUTRA-v9x0-IEs " the inside.Rear a kind of mode is exemplified below:
