Specifically, in scheme of the present invention, for network side, for any cell, when needing to carry out MDT
When, base station needs each terminal for carrying out drive test to send MDT measurement configuration message into cell, and required precision is notified to cell
The middle each terminal for needing to carry out drive test；Match somebody with somebody it is preferred that needing each terminal for carrying out drive test to send MDT measurements into cell in base station
Put message, and required precision notified, to before each terminal for needing to carry out drive test in cell, to can first determine whether that needs are
Cell configuration required precision, if it is, need each terminal for carrying out drive test to send MDT measurement configuration message into cell, and
Required precision is notified, to each terminal for needing progress drive test in cell, otherwise, required precision can not to be notified.The required precision
Refer to the required precision of positional information.
Each terminal for carrying out drive test is needed to determine to receive from base station for end side, in cell
MDT measurement configuration message, and after getting the required precision from base station, following handle can be carried out：Drive test is carried out, and determination is
It is no to get the positional information for meeting required precision, if it is, the positional information for meeting required precision that will be got

Data report base station together.Generally, each terminal for carrying out drive test is needed to determine to receive MDT measurement configuration message in cell,
And after getting required precision, can since in one section of scheduled duration current time, when meeting drive test trigger condition every time,
Perform the step in above-mentioned " following processing ".
To make technical scheme clearer, clear, develop simultaneously embodiment referring to the drawings, to of the present invention
Scheme is described in further detail.
Fig. 1 is the flow chart of MDT of the present invention implementation method embodiment.As shown in figure 1, comprise the following steps：
Step 11：For any cell, when needing to carry out MDT, base station determines the need for will for cell configuration precision
Ask, if it is desired, then need each terminal for carrying out drive test to send MDT measurement configuration message into cell respectively, and will by precision
Seek each terminal notified respectively to progress drive test is needed in cell.
For any cell, if need to configure required precision for it, can be determined by webmaster, as webmaster is found in a cell
Abnormal area be present, then can determine that is needed to configure required precision for it, and by specific required precision, how much rice be such as accurate to
Base station corresponding to cell is notified (such as 5 meters), meanwhile, base station can be notified to need how many individual terminals to carry out drive test etc..Or also may be used
To be determined the need for as cell configuration required precision, specific required precision by base station and be needed to carry out the terminal of drive test
Number etc., can be realized by configuring relevant information in a base station.
If it is determined that needing for cell configuration required precision, then base station needs to carry out each terminal of drive test respectively into cell
MDT measurement configuration message is sent, and required precision is notified to each terminal that progress drive test is needed in cell respectively.
Specifically choosing which terminal can be decided according to the actual requirements as the terminal for needing to carry out drive test.For example base station exists
Need each terminal for carrying out drive test to send MDT into cell respectively to measure before configuring message, can be by strengthening cell ID (E-
CID, Enhanced Cell ID) localization method gets the rough location of each terminal in cell, and then choose rough location and exist
In abnormal area (approximate region) or neighbouring terminal is as the terminal for needing progress drive test.
In actual applications, the number of terminals for needing to carry out drive test of selection can have certain redundancy, as webmaster notifies base
50 terminals of needs of standing carry out drive test, but base station can choose 60 terminals as the terminal for needing progress drive test, subsequently can be from 60
The reported result of individual terminal selects 50 preferably as required reported result.
As previously described, if it is determined that need to need into cell respectively except needs for cell configuration required precision, base station
Carry out drive test each terminal send MDT measurement configuration message outside, it is also necessary to required precision is notified respectively to needed in cell into
Each terminal that walking along the street is surveyed.Specifically, required precision is carried in MDT measurement configuration message, is also carried in system message
In broadcast etc..
In addition, base station can also need each terminal for carrying out drive test to send the precision lower limit that can be tolerated into cell respectively,
When the precision for the positional information that user to be reported is less than the thresholding, the data have little significance for network side, therefore can
Without reporting, to save interface-free resources and power consumption.Equally, the precision lower limit that can be tolerated is carried in MDT measurement configuration message
In, also it is carried in system message and broadcasts etc..The precision lower limit that can be tolerated can be determined by webmaster and notify to
Base station or be pre-configured with a base station.
Further, base station can also need the corresponding localization method of each terminal transmission for carrying out drive test excellent into cell respectively
First level list, as it was previously stated, the rough location of each terminal is understood, then can then be determined respectively according to the rough location of each terminal
The localization method priority list for being adapted to its position to use, wherein can have according to the journal of priority from high to low more
Individual localization method, such as assisted global navigational satellite system (A-GNSS, Assisted Global Navigation Satellite
System) localization method, descending positioning (Downlink Positioning) method etc..For the terminal of diverse location, due to
Influenceed by factors such as topography and geomorphologies, specific localization method may can more be got compared to other localization methods meets precision
It is required that positional information, so as to reduce the trial that terminal carries out unnecessary localization method.Localization method corresponding to each terminal
Priority list can be determined by webmaster and notify to determine to base station or by base station, and can by with each end
End carries out information exchange in advance, obtains its ability information, so as to ensure to occur without end in localization method priority list as far as possible
Hold the localization method do not supported.
Step 12：Need each terminal for carrying out drive test to determine to receive MDT measurement configuration message in cell, and get essence
After degree requires, since in one section of scheduled duration current time, when meeting drive test trigger condition every time, then following locate is carried out
Reason：Drive test is carried out, and determines whether that the positional information for meeting required precision can be got, if it is, the symbol that will be got
The positional information for closing required precision reports base station together with drive test data, if it is not, then by the precision that can be got most
Excellent positional information reports base station together with drive test data.
Need each terminal for carrying out drive test to receive MDT measurements configuration message in this step, in cell and get precision
After it is required that, since current time, to following one section of scheduled duration sometime in, when meeting drive test trigger condition every time
When, then drive test is carried out according to existing way, and determine whether that the positional information for meeting required precision can be got, if it is,
The positional information for meeting required precision got is then reported into base station together with drive test data, if it is not, then can
The optimal positional information of the precision that gets reports base station together with drive test data.
The drive test trigger condition, time triggered or the triggering of self-explanatory characters' part can be referred to, which kind of is specifically can be by net
Pipe determines, can also be determined by base station, and can carry together with above-mentioned scheduled duration etc. and be notified in MDT measures configuration message to cell
The middle each terminal for needing to carry out drive test.
Needed in cell carry out drive test each terminal can determine whether to get in such a way meet precision will
The positional information asked：
If 1) it is not received by localization method priority list
According to predefined procedure, determine whether the positional information that each localization method supported according to itself is got accords with successively
Required precision is closed, untill obtaining meeting the positional information of required precision；Concrete foundation which kind of sequentially can be according to being actually needed
Depending on；
If 2) receive localization method priority list
According to the order of priority from high to low, determine successively according to each localization method in localization method priority list
Whether the positional information got meets required precision, untill obtaining meeting the positional information of required precision.
1) or 2) in actual applications, each terminal for needing to carry out drive test in cell is according to the mode carries out handling it
Before, also it can first determine whether itself preserves the positional information got in advance due to certain demand, if it is, further
1) or 2) determine whether the precision of the positional information meets required precision, if it is, can not have to according still further to the mode is carried out
Processing, power consumption and interface-free resources are wasted so as to avoid unnecessary unlatching positioning service.In addition, obtained in place no in advance
When confidence ceases, whether it can also further determine that currently because certain demand has had turned on certain positioning service, if it is, entering one
Whether the precision for the positional information that step determines to get according to localization method corresponding to the positioning service meets required precision, if
1) or 2) be that can then not have to according still further to the mode is handled, so as to avoid unnecessary unlatching positioning service and power consumption and
Waste interface-free resources.If it cannot meet the positional information of required precision according to above two mode, according still further to 1) or 2)
The mode is handled.
1) or 2) if after the mode is handled, the positional information of required precision cannot still be met, then
The optimal positional information of the precision that can be got can be reported base station together with drive test data.Such as by localization method
After 5 localization methods recorded in priority list were attempted, it still cannot meet the positional information of required precision,
Assuming that the precision of the positional information got using the 3rd localization method is optimal, then will can then be obtained according to the 3rd localization method
The positional information got reports base station.The precision for the positional information for how determining to get according to each localization method is existing skill
Art.
Mentioned in step 11, base station can also need each terminal for carrying out drive test to send the essence that can be tolerated into cell respectively
Spend lower limit, then, can be true first after correspondingly, in cell needing each terminal for carrying out drive test to obtain the optimal positional information of precision
Whether the precision of the optimal positional information of precision is determined less than the precision lower limit that can be tolerated, if it is, without reporting, if
It is no, then reported.
In addition, also proposed a kind of update mechanism in scheme of the present invention, including to required precision and can tolerate
Precision lower limit renewal, and the renewal to localization method priority list introduces individually below.
1) to required precision and the renewal for the precision lower limit that can be tolerated
To realize to required precision and the renewal for the precision lower limit that can be tolerated, need to carry out each end of drive test in cell
End is while the positional information of itself is reported, it is also necessary to reports the precision of reported positional information.As it was previously stated, how to obtain
The precision for taking positional information is prior art.
Correspondingly, can be reported at interval of scheduled duration, base station or webmaster according to each terminal in nearest one section of scheduled duration
The precision lower limit that the precision of positional information determines once whether to need required precision to cell and can tolerated is updated,
Such as increase or reduce, if it is, being sent to the required precision after renewal and the precision lower limit that can be tolerated by base station
Each terminal of progress drive test is needed in cell；Need to carry out in cell each terminal of drive test according to the required precision after renewal and
Positional information after the precision lower limit that can tolerate is carried out reports.
Wherein, the precision for the positional information that webmaster or base station can report to each terminal in nearest one section of scheduled duration adds
The processing such as weight average, so as to obtain an overall accuracy on cell, and is determined the need for small according to the overall accuracy
The required precision in area and the precision lower limit that can be tolerated are updated.
It should be noted that if base station does not need each terminal for carrying out drive test to send the precision that can be tolerated into cell
Lower limit, then without being updated to the precision lower limit that can be tolerated.
2) to the renewal of localization method priority list
To realize the renewal to localization method priority list, each terminal for needing to carry out drive test in cell is on first time
While reporting the positional information of itself, it is also necessary to report predetermined information, the predetermined information includes：Obtain this position reported
Localization method used in information, to obtain the localization method that this positional information reported was attempted, and according to being reported
The precision of positional information that gets respectively of each localization method.
Afterwards, when needing to carry out each terminal of drive test in cell every time (other each times i.e. in addition to reporting for the first time report)
When reporting the positional information of itself, before determining to obtain the localization method used in the positional information that this is reported respectively compared to acquisition
Whether the localization method used in positional information once reported is changed, if it is, the predetermined information is reported simultaneously,
If it is not, then the predetermined information need not be reported.
Correspondingly, can be reported at interval of scheduled duration, base station or webmaster according to each terminal in nearest one section of scheduled duration
Predetermined information determines once whether need to needing to carry out localization method priority list corresponding to each terminal of drive test in cell
It is updated, as adjusted the priority of each localization method in localization method priority list or deleting that certain precision is excessively poor to determine
Position method etc., and the localization method priority list after renewal is sent to corresponding terminal by base station；Corresponding terminal according to
Positional information after localization method priority list after renewal is carried out reports.
In actual applications, each terminal for carrying out drive test is needed to carry each information for reporting base station in cell
Base station is sent in MDT measurement report messages.The MDT measurement report messages can be UEInformationResponse message
Or Measurement Report message etc..
Wherein, if terminal is in Idle states, each information reported is carried in UEInformationResponse
Base station is sent in message, if terminal is in connection status, each information reported is carried in Measurement
Base station is sent in Report message.UEInformationResponse message and Measurement Report message are
Wireless heterogeneous networks (RRC, Radio Resource Control) message.Specifically, can will be in addition to existing drive test data
The other each information to be reported carry UEInformationResponse message logMeasReport-r10 fields or
In the MeasResultEUTRA fields of Measurement Report message.
In addition, base station can (such as required precision, precision lower limit, the localization method that can be tolerated be preferential by the information after renewal
Level list) carry in MDT measurement configurations message, the RRC information newly defined newly defined, or be sent in system message corresponding
Terminal.
In above example, illustrated exemplified by needing for cell configuration required precision, below to that need not be cell
The situation of configuration required precision illustrates.
If it need not be cell configuration required precision, then base station needs to need each terminal for carrying out drive test into cell
MDT measurement configuration message is sent, but without required precision is notified to each terminal that progress drive test is needed in cell.Namely
Say, required precision need not be carried in MDT measurement configuration message, further, instruction can be carried eventually in MDT measures configuration message
End obtains the configured information of positional information according to the principle for guarantee of trying one's best, or, configured information can also be carried
Broadcasted etc. in system message.
Need each terminal for carrying out drive test to determine to receive MDT measurement configuration message in cell, but do not get precision and want
After asking, regardless of whether receiving above-mentioned configured information, itself can be reported to base station according to the principle for guarantee of trying one's best
Positional information, it is implemented as prior art.
In addition, base station can also need each terminal for carrying out drive test to send the precision lower limit that can be tolerated into cell respectively；
Correspondingly, given the correct time when each terminal that progress drive test is needed in cell has on positional information needs, it is determined that the positional information to be reported
Precision whether less than the precision lower limit that can tolerate, if it is, without reporting, if it is not, then being reported.
Further, each terminal for needing to carry out drive test in cell can also report institute while the positional information of itself is reported
The precision of the positional information reported；Correspondingly, at interval of scheduled duration, base station or webmaster according to each in nearest one section of scheduled duration
The precision for the positional information that terminal reports determines once whether need to be updated the precision lower limit that can be tolerated of cell, such as
Fruit is that the precision lower limit that can be tolerated after renewal is then sent to each terminal for needing to carry out drive test in cell by base station；It is small
Each terminal for needing to carry out drive test in area is according to the upper of the positional information after the precision lower limit that can the be tolerated progress after renewal
Report.
When terminal is moved to new cell, according to required precision of new cell etc., again using the positioning being more suitable for
Method obtains reporting for positional information, row positional information of going forward side by side etc..
