Embodiment
For overcoming problems of the prior art, need to all carry out certain improvement to network side and end side.
Specifically, in scheme of the present invention, for network side, for arbitrary community, when carrying out MDTShi， base station, in community, need each terminal of carrying out drive test to send MDT measurement configuration messages, and required precision is notified to each terminal that needs to carry out drive test in community; Preferably, in base station, in community, need each terminal of carrying out drive test to send MDT measurement configuration messages, and required precision is notified to before needing to carry out each terminal of drive test in community, can first determine whether need to be cell configuration required precision, if in ，Ze Xiang community, need each terminal of carrying out drive test to send MDT measurement configuration messages, and required precision is notified to each terminal that needs to carry out drive test in community, otherwise, can not notify required precision.Described required precision refers to the required precision of positional information.
Correspondingly, for end side, in community, need each terminal of carrying out drive test to determine that the MDT receiving from base station measures configuration messages, and get after the required precision from base station, can carry out following processing: carry out drive test, and determine whether to get the positional information that meets required precision, if, the positional information that meets required precision getting is reported to base station together with drive test data, the positional information of the precision optimum that can get if not, reports base station together with drive test data.Conventionally, in community, need each terminal of carrying out drive test to determine that receiving MDT measures configuration messages, and get after required precision, in one section of scheduled duration that can start from current time, when meeting drive test trigger condition, carry out the step in above-mentioned " processing below " at every turn.
For make technical scheme of the present invention clearer, understand, referring to the accompanying drawing embodiment that develops simultaneously, scheme of the present invention is described in further detail.
Fig. 1 is the flow chart of the implementation method embodiment of MDT of the present invention.As shown in Figure 1, comprise the following steps:
Step 11: for arbitrary community, when needs carry out MDT, base station determines whether need to be cell configuration required precision, if needed, in community, need each terminal of carrying out drive test to send MDT measurement configuration messages respectively, and required precision is notified respectively to each terminal that needs to carry out drive test in community.
For arbitrary community, whether need for its configuration required precision, can be determined by webmaster, as webmaster is found to have abnormal area in a community, can determine need to be for it configures required precision, and by concrete required precision, as be accurate to how many rice (as 5 meters) notice to base station corresponding to community, meanwhile, can need how many terminals to carry out drive test etc. by informing base station.Or, also can be determined whether and need to carry out number of terminals of drive test etc. for cell configuration required precision, concrete required precision by base station, can realize by configure relevant information in base station.
If determine and need to measure configuration messages for cell configuration required precision ，Ze base station sends MDT to each terminal that needs to carry out drive test in community respectively, and required precision is notified respectively to each terminal that needs to carry out drive test in community.
Specifically choosing which terminal can be decided according to the actual requirements as the terminal that need to carry out drive test.Such as, base station is sending to each terminal that needs to carry out drive test in community respectively before MDT measures configuration messages, can be by strengthening cell ID (E-CID, Enhanced Cell ID) localization method gets the preliminary position of each terminal in community, then choose preliminary position in abnormal area (approximate region) or near terminal as the terminal that need to carry out drive test.
In actual applications, the number of terminals that need to carry out drive test of choosing can have certain redundancy, as needing 50 terminals, webmaster informing base station carries out drive test, but 60 terminals can be chosen as the terminal that need to carry out drive test in base station, follow-uply can select 50 preferably as required reported result from the reported result of 60 terminals.
As previously mentioned, if determine need to be cell configuration required precision, base station sends MDT measurement configuration messages except needs need respectively each terminal of carrying out drive test in community, also needs required precision to notify respectively to each terminal that needs to carry out drive test in community.Specifically, required precision is carried in MDT and measures in configuration messages, is also carried in system message, to broadcast etc.
In addition, base station also can be respectively need each terminal of carrying out drive test to send the precision lower limit that can tolerate in community, and the precision of the positional information that will report as user is during lower than this thresholding, and these data have little significance for network side, therefore can report, to save interface-free resources and power consumption.Equally, the precision lower limit that can tolerate is carried in MDT and measures in configuration messages, is also carried in system message, to broadcast etc.The precision lower limit that can tolerate can be determined and be notified to base station by webmaster, also can be pre-configured in base station.
Have again, base station also can need each terminal of carrying out drive test to send the localization method priority list corresponding with it respectively in community, as previously mentioned, the preliminary position of each terminal is known, so can determine respectively and be applicable to the localization method priority list that its position is used according to the preliminary position of each terminal, wherein can there be a plurality of localization methods according to priority journal from high to low, as assisted global navigational satellite system (A-GNSS, Assisted Global Navigation Satellite System) localization method, descending location (Downlink Positioning) method etc.For the terminal of diverse location, owing to being subject to the impact of the factors such as topography and geomorphology, specific localization method may more can get the positional information that meets required precision than other localization method, thereby can reduce the trial that terminal is carried out unnecessary localization method.Localization method priority list corresponding to each terminal can be determined and be notified to base station by webmaster, also can Shi You base station determine, and can be by carrying out in advance information interaction with each terminal, obtain its ability information, thereby guarantee not occur the localization method that terminal is not supported as far as possible in localization method priority list.
Step 12: need each terminal of carrying out drive test to determine that receiving MDT measures configuration messages in community, and get after required precision, in the one section of scheduled duration starting from current time, when meeting drive test trigger condition at every turn, carry out following processing: carry out drive test, and determine whether to get the positional information that meets required precision, if, the positional information that meets required precision getting is reported to base station together with drive test data, the positional information of the precision optimum that can get if not, reports base station together with drive test data.
In this step, in community, need each terminal of carrying out drive test receive MDT measurement configuration messages and get after required precision, from current time, in following one section of scheduled duration sometime, when meeting drive test trigger condition at every turn, according to existing mode, carry out drive test, and determine whether to get the positional information that meets required precision, if, the positional information that meets required precision getting is reported to base station together with drive test data, if not, the positional information of the precision optimum that can get reports base station together with drive test data.
Described drive test trigger condition, the time that can refer to triggers, and also can refer to Event triggered, and specifically which kind of can be determined by webmaster, Ye Keyou base station determines, and can be carried at MDT together with above-mentioned scheduled duration etc. and measure in configuration messages notice to each terminal that needs to carry out drive test in community.
In community, need each terminal of carrying out drive test can determine whether in such a way to get the positional information that meets required precision:
1) if do not receive localization method priority list
According to predefined procedure, whether the positional information that definite each localization method of supporting according to self gets successively meets required precision, until obtain meeting the positional information of required precision; Which kind of specifically according to order, can be decided according to the actual requirements;
2) if receive localization method priority list
According to priority order from high to low, determine successively whether the positional information getting according to each localization method in localization method priority list meets required precision, until obtain meeting the positional information of required precision.
In actual applications, each terminal that needs to carry out drive test in community is according to 1) or 2) before described mode processes, also can first determine whether self preserves the positional information getting in advance due to certain demand, if, whether the precision of further determining this positional information meets required precision, if so, can be again according to 1) or 2) described mode processes, thereby avoid unnecessary unlatching positioning service and power consumption and waste interface-free resources.In addition, when not getting positional information in advance, also can further determine current whether because certain demand has been opened certain positioning service, if, whether the precision of further determining the positional information getting according to localization method corresponding to this positioning service meets required precision, if so, can be again according to 1) or 2) described mode processes, thereby avoid unnecessary unlatching positioning service and power consumption and waste interface-free resources.If all can not get meeting the positional information of required precision according to above-mentioned two kinds of modes, then according to 1) or 2) described mode processes.
If according to 1) or 2) after described mode processes, still can not get meeting the positional information of required precision, the positional information of the precision optimum that can get can be reported to base station together with drive test data.Such as, after 5 localization methods that record in localization method priority list were all attempted, still can not get meeting the positional information of required precision, suppose to utilize the precision of the 3rd positional information that localization method gets optimum, so can will report base station according to the 3rd positional information that localization method gets.The precision of the positional information that how to confirm gets according to each localization method is prior art.
In step 11, mention, base station also can need each terminal of carrying out drive test to send the precision lower limit that can tolerate respectively in community, so correspondingly, in community, need each terminal of carrying out drive test to obtain after the positional information of precision optimum, can first determine that the precision of positional information of precision optimum, whether lower than the precision lower limit that can tolerate, if so, does not report, if not, report.
In addition, in scheme of the present invention, also proposed a kind of update mechanism, comprised the renewal to required precision and the precision lower limit that can tolerate, and the renewal to localization method priority list, below introduced respectively.
1) renewal to required precision and the precision lower limit that can tolerate
For realizing the renewal to required precision and the precision lower limit that can tolerate, in community, need each terminal of carrying out drive test when reporting the positional information of self, also need to report the precision of reported positional information.As previously mentioned, precision how to obtain positional information is prior art.
Correspondingly, at interval of scheduled duration, whether base station or webmaster can once need the required precision of community and the precision lower limit that can tolerate to upgrade according to the determine precision of the positional information of each terminal to report in nearest one section of scheduled duration, as increased or reducing etc., if ，Ze You base station sends to by the required precision after upgrading and the precision lower limit that can tolerate each terminal that needs to carry out drive test in community; Reporting of the positional information of each terminal that needs to carry out drive test in community after carrying out according to the required precision after upgrading and the precision lower limit that can tolerate.
Wherein, webmaster or base station can be weighted flat equalization process to the precision of the positional information of each terminal to report in nearest one section of scheduled duration, thereby obtain one about the overall accuracy of community, and determine whether to upgrade the required precision of community and the precision that can tolerate lower limit according to this overall accuracy.
It should be noted that, if need each terminal of carrying out drive test to send the precision lower limit that can tolerate in Wei Xiang community, base station, without the precision lower limit to tolerating, upgrade.
2) renewal to localization method priority list
For realizing the renewal to localization method priority list, in community, need each terminal of carrying out drive test when reporting for the first time the positional information of self, also need to report predetermined information, described predetermined information comprises: obtain this positional information reporting localization method used, be to obtain the localization method that this positional information reporting was attempted and the precision of the positional information getting respectively according to each reported localization method.
Afterwards, when each terminal each (i.e. other each time except reporting for the first time reports) that needs to carry out drive test in community reports the positional information of self, determine respectively whether obtain this positional information reporting localization method used, than the positional information localization method used once reporting before obtaining, variation has occurred, if, report described predetermined information simultaneously, if not, without reporting described predetermined information.
Correspondingly, at interval of scheduled duration, base station or webmaster can determine once whether need needing localization method priority list corresponding to each terminal that carries out drive test to upgrade in community according to the predetermined information of each terminal to report in nearest one section of scheduled duration, as adjusted the priority of each localization method in localization method priority list or delete the excessively poor localization method Deng，Bing You base station of certain precision, the localization method priority list after upgrading is sent to corresponding terminal; Corresponding terminal is carried out reporting of positional information afterwards according to the localization method priority list after upgrading.
In actual applications, each terminal that needs in community to carry out drive test can be carried at each information that reports base station in MDT measurement report message and send to base station.Described MDT measurement report message can be UEInformationResponse message or Measurement Report message etc.
Wherein, if terminal is in Idle state, each information reporting is carried in UEInformationResponse message and sends to base station, if terminal, in connection status, is carried at each information reporting in Measurement Report message and sends to base station.UEInformationResponse message and Measurement Report message are Radio Resource and control (RRC, Radio Resource Control) message.Specifically, other each information that will report except existing drive test data can be carried in the logMeasReport-r10 field of UEInformationResponse message or the MeasResultEUTRA field of Measurement Report message.
In addition, the MDT that base station can be carried at the information (as required precision, the precision lower limit that can tolerate, localization method priority list) after upgrading new definition measures the RRC message of configuration messages, new definition, or in system message, sends to corresponding terminal.
In above embodiment, the needs of take describe as cell configuration required precision as example, below to not needing, for the situation of cell configuration required precision, describe.
If do not needed for cell configuration required precision, base station need to need each terminal of carrying out drive test to send MDT measurement configuration messages in community so, but without required precision being notified to each terminal that needs to carry out drive test in community.That is to say, MDT measures in configuration messages without carrying required precision, further, can measure and in configuration messages, carry the indication information that principle that indicating terminal guarantees according to trying one's best is obtained positional information at MDT, or, also indication information can be carried in system message and broadcast etc.
In community, need each terminal of carrying out drive test to determine that receiving MDT measures configuration messages, but do not get after required precision, no matter whether receive above-mentioned indication information, all can to base station, report the positional information of self according to the principle guaranteeing of trying one's best, specific implementation is prior art.
In addition, base station also can need each terminal of carrying out drive test to send the precision lower limit that can tolerate respectively in community; Each terminal that correspondingly needs to carry out drive test in ，Dang community has on positional information needs gives the correct time, and determines that the precision of the positional information that will report, whether lower than the precision lower limit that can tolerate, if so, does not report, and if not, reports.
In Zai You， community, need each terminal of carrying out drive test when reporting the positional information of self, also can report the precision of reported positional information; Correspondingly, at interval of scheduled duration, whether base station or webmaster once need the precision lower limit that can tolerate of community to upgrade according to the determine precision of the positional information of each terminal to report in nearest one section of scheduled duration, if ，Ze You base station sends to by the precision lower limit that can tolerate after upgrading each terminal that needs to carry out drive test in community; In community, need each terminal of carrying out drive test to carry out reporting of positional information afterwards according to the precision lower limit that can tolerate after upgrading.
When fast mobile terminal Dao Xin community, according to the required precision of Xin community etc., again adopt the localization method being more suitable for to obtain positional information, the reporting of the line position information of going forward side by side etc.
