Background technology
In a communications system, in order to ensure network communication quality, it is necessary to using drive test technical testing network communication quality.Pass The drive test technology of system needs staff to reach each test point, and the network of each test point is obtained using special instrument Communication quality, to detect network coverage situation.As can be seen here, using traditional drive test technical testing network communication quality, it is necessary to Expend substantial amounts of manpower and materials.
For the above-mentioned test problems to network coverage situation, the third generation Partnership Program (abbreviation 3GPP) tissue is proposed MDT(Minimization Drive Tests；Minimize drive test) technology, the UE (User in the direct application network of the technology Equipment；User equipment) to base station report network communication quality, base station is obtained network coverage situation, so as to effectively keep away While having exempted from the consumption of human and material resources, can user can actually reach in overlay network any place, cover model Enclose the coverage for being far longer than measurable network communication quality during using traditional drive test technology.
In a communications system, the minimum particle size of MDT measurement activities NMS initiated to UE is defined as one MDT trace sessions (MDT Trace Session).According to the difference of MDT measuring system frameworks, MDT trace sessions can be divided into MDT (Area) measurements and the measurements of the MDT based on signaling based on region：MDT measurements based on region refer to a MDT tracking meeting Talk about the process that the UE triggered in designated area is carried out MDT measurements and reports MDT measurement result；MDT measurements based on signaling Refer to that a MDT trace session only triggers some special user equipment or some specific IMSI (International Mobile Subscriber Identity；IMSI International Mobile Subscriber Identity) corresponding to UE carry out MDT measurements and measure MDT The process that result is reported.According to the difference of MDT metering systems, MDT trace sessions can be divided into formula MDT (Immediate immediately MDT) measurement and recording MDT (Logged MDT) measurements：Immediate MDT measurements refer to UE in RRC (Radio Resource Control；Wireless heterogeneous networks) for connected state when measure, using Immediate MDT measurement can and When MDT measurement result is reported into base station；Logged MDT measurements refer to that UE is measured when RRC is Idle state, and only MDT measurement result is reported into base station after RRC returns to connected state, therefore, generally existed using Logged MDT measurements larger Time delay.
In a communications system, above-mentioned MDT trace sessions are by NM (the Network Manager in NMS；Net Network administrative unit) initiate, herein, the process that above-mentioned NM initiates a MDT trace session is referred to as one MDT tracking meeting of activation Words, the process that NM stops a MDT trace session is referred to as to deactivate a MDT trace session.
For the MDT measurements based on region, use MDT technologies carry out the process of network communication quality measurement for：Network pipe EM (Element Manager in reason system；NE management unit) MDT measurement initiation message is sent to UTRAN (Universal Terrestrial Radio Access Network；Universal Terrestrial Radio Access Network) in base station it is corresponding RNC(Radio Network Controller；Radio network controller) or E-UTRAN (Evolved UTRAN, evolution it is logical With grounding wireless access network) in eNB (Evolved NodeB, the node B of evolution) with initiate MDT measurement；Base station receives above-mentioned After message is initiated in MDT measurements, you can selection meets the UE configuration MDT measurements that 3GPP agreements specify, that is, select and do not configure MDT surveys Amount, and the UE in the configurable MDT measurement cells specified, base station obtains the MDT measurement knots that above-mentioned selected UE is reported After fruit, you can network communication quality is estimated according to the MDT measurement result.And for the MDT measurements based on signaling, use The process that MDT technologies carry out network communication quality measurement is：Because the MDT measurements based on signaling configure MDT for the UE for specifying Measurement, therefore, it is that the above-mentioned UE configurations MDT for specifying is measured and set MDT measurements with confidence after base station obtains the UE that EM is specified Breath, after base station obtains the MDT measurement result that above-mentioned selected UE is reported, you can according to the MDT measurement result to network service matter Amount is estimated.
For Immediate MDT measurements, the base station that the initiation and end that MDT is measured are UE offer services is directly controlled System, and for Logged MDT measurements, the initiation of MDT measurements is directly controlled by the base station that service is provided for the UE, MDT measurements Terminate to be that the MDT record durations that the UE is configured are controlled during by initiating, i.e., when Logged MDT are initiated in base station for certain UE During measurement, it is impossible to control the UE to stop above-mentioned MDT and measure, and the corresponding MDT records of the timer in the UE can only be waited to continue After duration time-out, control the UE to stop MDT and measure.
The process of network communication quality measurement is carried out from above-mentioned use MDT commercial measurements, for the MDT based on region Measurement, only being carried in the MDT measurement initiation message that base station reception EM sends can carry out the cell information of MDT measurements, you can think Particular UE in specified cell sets MDT measurement configuration informations, therefore, base station can only obtain and be not provided with MDT measurements and match somebody with somebody UE lists and the UE lists of MDT measurement configuration informations have been set that confidence ceases, and arranged from the UE for being not provided with MDT measurement configuration informations Randomly choosed in table and authorize the UE of configurable MDT measurements that MDT measurement configuration informations are set, so that in the presence of selected all UE positions Compare concentration, it is impossible to reflect the network communication quality of each test point under network coverage, the network for obtaining base station leads to Letter quality measurements can not comprehensively reflect the problem of network coverage, also, when setting in all cells of base station administration The number of the UE of MDT measurement configuration informations reflects network coverage situation comprehensively by reaching certain amount (such as M), and base station is administered All cells in actual setting MDT measurement configuration informations UE number (N) be more than above-mentioned M when, base station cannot adjust its pipe The corresponding MDT measuring states of UE in any one cell of linchpin, consumption is measured so as to increased unnecessary MDT.

Specific embodiment
During in order to solve to be measured for the MDT measurement configurations MDT based on region, it is poor to there is selected UE composite indexes, The network coverage situation that base station obtains is not comprehensive, the excessive problem of MDT measurement resource consumptions.In the embodiment of the present invention, receive It is according to the corresponding load information of each cell of local administration and default negative when message is initiated in the MDT measurements that EM sends Information carrying ceases threshold value, and the MDT measurement configuration statuses of each cell are judged respectively；When the MDT measurements for judging any one cell are matched somebody with somebody Configuration state is unrestricted for configuration, and is first when there is the UE for meeting default MDT configuration conditions in any one cell UE sets MDT measurement configuration informations；Overloaded as configuration when the MDT for judging any one cell measures configuration status, and this is any one When there is two UE for meeting default MDT regularization conditions in cell, the corresponding MDT measurements of the 2nd UE are deleted or reconfigured Configuration information.Using technical solution of the present invention, base station can respectively for the corresponding MDT measurements configuration status in different districts, choosing Select and meet the UE of default MDT configuration conditions and MDT measurement configuration informations are set, are deleted or is reset and meet default MDT The corresponding MDT measurement configuration informations of UE of regularization condition, the MDT of cell measures configuration status with reference to where UE, selects more excellent UE reports MDT measurement result, so that the MDT measurement consumption in base station is smaller, and can obtain the more accurate network coverage Situation.
The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.
The corresponding network architecture schematic diagram of the embodiment of the present invention is shown refering to Fig. 1, wherein, the network architecture includes EM, Base station, and UE.
Refering to shown in Fig. 2, in the embodiment of the present invention, the detailed process for being UE configuration MDT measurements is：
Step 200：When message is initiated in the MDT measurements that base station receives EM transmissions, according to each cell of local administration Corresponding load information, and default load information threshold value, judge the MDT measurement configuration statuses of each cell respectively.
In the embodiment of the present invention, after base station receives the MDT measurement initiation message that EM sends, you can triggering MDT measurement configurations Flow.Wherein, above-mentioned MDT measurements are initiated to carry the cell (hereinafter referred to as can configure cell) that can carry out MDT measurements in message, when Exist in above-mentioned configurable cell EM authorize can configure MDT measurement UE when, can to the UE set MDT measurement match somebody with somebody confidence Breath.Base station can obtain the MDT measurement configuring conditions that the corresponding EM of any one UE are authorized from EM.
Preferably, due in NMS, there is a base station or multiple base stations, when in the presence of multiple base stations When, triggering MDT measurement configuration flows during in order to ensure different between multiple base stations to greatest extent, base station receives what EM sent After message is initiated in MDT measurements, OAM (Operation, Administration and Maintenance are obtained；Operation, management With safeguard) the delay duration scope of systemic presupposition, base station random selection in the range of the default delay duration is local corresponding Postpone duration, start delay timer, the delay timer a length of randomly selected delay duration in base station when corresponding maximum. For example, being by the delay duration scope of OAM systemic presuppositions【0, Tmdt】, wherein, TmdtIt is optional maximum duration, base station can be from this Postpone the local corresponding delay duration of random selection in the range of duration.
Using above-mentioned preferably technical scheme, can to greatest extent ensure that each base station sets MDT for its corresponding UE The moment of measurement configuration information is differed, and this UE pairs can be detected with configured information with the record measurement for facilitating base station to be reported according to UE Whether the MDT measurement configuration informations answered are to be locally located.By taking recording MDT measurements as an example, specific detection method is：When UE connects When entering current base station, i.e., can report the record measurement can be with configured information to base station, record measurement can be carried with configured information The corresponding MDT measurements configuration parameters of UE, comprising TRSR (Trace Recording Session Reference；Keep track of into Journey reference) and absolute time information (absoluteTimeInfo) etc., it is available that base station receives the record measurement that certain UE reports After configured information, all MDT that set recorded by the TRSR and absolute time information and the inside of base station that wherein carry are measured The corresponding TRSR of UE and absolute time information of configuration information compare, and check whether both is identical.If it is above-mentioned both It is identical, then it represents that the corresponding MDT measurement configuration informations of above-mentioned UE are by being locally located.In the embodiment of the present invention, using in time delay In the range of duration, different delay durations are randomly choosed to different base stations to ensure that different base station is matched somebody with somebody for UE sets MDT measurements The absolute time information of confidence breath is different；Also, standard gauge is scheduled in same base station the TRSR differences set for different UE, because This, same base station can be distinguished not for different UE according to the TRSR carried in its corresponding MDT measurement configuration information Same UE, that is, use absolute time information and TRSR to uniquely determine a MDT and keep track of process.
In the embodiment of the present invention, base station is to be the UE while UE configurations MDT is measured to set MDT measurement configuration informations, After base station preserves above-mentioned MDT measurement configuration informations, UE can carry out MDT measurements and MDT measurement result is reported into base station, base station Network communication quality, and network coverage situation are obtained according to the MDT measurement result.By the above-mentioned UE for carrying out MDT measurements The UE of MDT measurement configuration informations has referred to as been set；Terminate when the corresponding MDT measurement configuration informations time-out of UE or by current base station When, then the UE is that stopping carries out MDT measurements, and the UE for not carrying out MDT measurements is referred to as being not provided with the UE of MDT measurement configuration informations.
After the corresponding duration of above-mentioned delay timer is reached, to should delay timer base station triggers MDT measurements just Secondary configuration flow, i.e. base station are that the UE for meeting MDT configuration limits conditions sets MDT measurement configuration informations for the first time, specially：Selection Meet the UE of default MDT configuration limits condition, and for the UE of selection sets MDT measurement configuration informations；Also, selected each time During selecting, if in the presence of at least two meet default MDT configuration limits condition UE when, selection MDT measurement allocation index most UE high sets MDT measurement configuration informations.In the embodiment of the present invention, MDT measurement allocation indexs include the stationkeeping ability parameter of UE, The location parameter of UE, the translational speed of UE, and the corresponding channel quality parameters of UE；First configuration process is measured in above-mentioned MDT In, base station only selects a UE to set MDT measurement configuration informations each time, is that UE sets MDT measurement configuration informations each time Afterwards, judge whether the current number of the UE for having set MDT measurement configuration informations reaches default first threshold value, when it is determined that When the current number for setting the UE of MDT measurement configuration informations reaches default first threshold value, terminate to match somebody with somebody for UE sets MDT measurements The process of confidence breath, otherwise, continuation selects the UE for meeting MDT configuration limits conditions to carry out MDT and measures configuration.
In the embodiment of the present invention, above-mentioned MDT configuration limits condition refers to that message is initiated in the MDT measurements that base station sends according to EM The configurable cell for determining, and there is the UE of the configurable MDT measurements of EM mandates in the configurable cell, while meeting above-mentioned Two UE of condition can set MDT measurement configuration informations；Above-mentioned default first threshold value is that base station current time is most Number (the N of the UE of MDT measurement configuration informations can be setmax_add), it is that the default ginseng in each base station is directed to by OAM systems Number.
During base station sets MDT measurement configuration informations for the first time for UE, default MDT is met when having at least two During the UE of configuration limits condition, selection MDT measurement allocation index highests UE sets the detailed process of MDT measurement configuration informations For：The maximum UE of regioselective ability parameter sets MDT measurement configuration informations, and herein, stationkeeping ability parameter refers to rule in standard The corresponding stationkeeping ability parameter of positioning method of fixed UE, such as independent GNSS (Global Navigation Satellite System；GLONASS) positioning method and base station received signal-sending signal time difference measurements positioning method, its In, the corresponding stationkeeping ability parameter of independent GNSS positioning methods is maximum, i.e., when the positioning method of UE is independent GNSS positioning During mode, the stationkeeping ability of the UE is most strong；Now, if still suffering from least two stationkeeping ability parameter identical UE, position is selected Put parameter maximum UE and MDT measurement configuration informations are set, herein, location parameter maximum refers to have matched somebody with somebody relative to having set MDT measurements The UE of confidence breath apart from the farthest UE for meeting MDT configuration limits conditions, when in any one cell of base station administration in the absence of When the UE for meeting MDT configuration limits conditions of MDT measurement configuration informations is set, then any position of base station administration can be randomly choosed That puts meets the UE of MDT configuration limits conditions, and MDT measurements have been set with confidence when there is multiple in all cells of base station administration During the UE of breath, then random first UE to be selected that obtains has set MDT measurement configuration informations with each from above-mentioned UE to be selected The distance between UE, calculate putting down for above-mentioned first UE select and the distance of all UE that MDT measurement configuration informations have been set Average, continues the second UE to be selected of acquisition average with all distances for having set MDT measurement configuration informations according to the method described above Value, compares the average value of above-mentioned two distance, and the UE of the average value maximum of chosen distance is used as the maximum UE of location parameter；If still In the presence of at least two location parameter identical UE, then select translational speed maximum UE that MDT measurement configuration informations are set；If to upper After stating multiple parameters relatively, at least two translational speed identical UE are still suffered from, then the UE for selecting channel quality parameter minimum sets MDT measurement configuration informations are put, to ensure that base station can accurately and comprehensively obtain network of network coverage condition and communication matter Measure position of problems.
Special, when the number of the UE for having set MDT measurement configuration informations is less than default first threshold value, and base station is managed When in any one cell of linchpin in the absence of the UE for meeting MDT configuration limits conditions, terminate to set MDT measurement configuration information mistakes for UE Journey.
After the process of MDT measurement configuration informations is terminated to be set for the first time for UE in base station, preferably, starting MDT measurement configurations Timer, the corresponding duration (T of MDT measurement configuration timersmdt) by OAM system configurations, timer is configured not in MDT measurements When overtime, base station obtains the corresponding load information of each cell locally administered at current time, including base station current time sheet The corresponding ascending resource occupancy of each cell of ground administration, and the MDT measurements of setting that current time is locally stored are matched somebody with somebody The corresponding MDT measurement configuration informations of UE of confidence breath take memory space value.Further, base station obtains local current residual and deposits Storage spatial value.
The corresponding ascending resource occupancy (R of each cell that base station will obtaini), MDT measurement configuration informations take and deposit Storage spatial value (MMDT), and default load information threshold value is compared, and according to comparative result, obtains each cell MDT measures configuration status.In the embodiment of the present invention, for E-UTRAN systems, base station can count the corresponding PRB of each cell (Physical Resource Block；Ascending physical signal Resource Block) resources occupation rate as ascending resource occupancy, for UTRAN systems, can count the corresponding E-DCH of each cell (Enhanced-Dedicated Channel；Enhanced special letter Road) resources occupation rate as ascending resource occupancy.Wherein, above-mentioned base station acquisition current time local each administered is small The corresponding load information in area, including the corresponding ascending resource occupancy of each cell that base station current time locally administers, with And the corresponding MDT measurement configuration informations of the UE for having set MDT measurement configuration informations that current time is locally stored take storage sky Between be worth；Default load information threshold value includes default first ascending resource occupancy, and default second ascending resource takes Rate, default first memory space value, and default second memory space value.
In the embodiment of the present invention, after the corresponding load information of each cell of the local administration of acquisition, when above-mentioned MDT is surveyed After amount configuration timer expiry, or (i.e. the average uplink resource of all cells of base station administration is accounted for when the corresponding load in base station With rate) reach preset first threshold value after, or after current residual storage space value in base station is less than default Second Threshold, base station according to The corresponding ascending resource occupancy of each cell for obtaining, MDT measurement configuration informations take memory space value, and default Load information, judges the MDT measurement configuration statuses of each cell.Detailed process is：When the corresponding ascending resource of cell takes Rate is less than default first ascending resource occupancy (Ri<R1), and above-mentioned MDT measurement configuration informations take memory space value be less than Default first memory space value (MMDT<M1) when, judge that the cell is unrestricted as MDT measurement configurations；When cell is corresponding up Resources occupation rate is more than or equal to default first ascending resource occupancy, less than default second ascending resource occupancy (R1≤Ri <R2), and above-mentioned MDT measurement configuration informations take memory space value less than default second memory space value (MMDT<M2) when, sentence The fixed cell is that MDT measurement configurations are limited；Wherein, above-mentioned default first ascending resource occupancy is up less than default second Resources occupation rate, default first memory space value is less than default second memory space value；When the corresponding ascending resource of cell Occupancy is less than default second ascending resource occupancy (Ri<R2), and above-mentioned MDT measurement configuration informations take memory space value More than or equal to default first memory space, less than default second memory space value (M1≤MMDT<M2) when, judge the cell as MDT measurement configurations are limited；When the corresponding ascending resource occupancy of cell is more than or equal to default second ascending resource occupancy (Ri ≥R2), or above-mentioned MDT measurement configuration informations occupancy memory space value is more than or equal to default second memory space value (MMDT≥M2) When, judge that the cell is MDT measurement configuration overloads.
In the embodiment of the present invention, in any one cell of base station administration, when set the UE of MDT measurement configuration informations by Current base station is moved to other base stations；Or the corresponding MDT of UE be measured as recording MDT measure when, due to recording MDT measurement It is to be initiated by base station, and could only terminates when recording MDT measures time-out, therefore, the UE of MDT measurement configuration informations has been set In the presence of the situation that the change of MDT measuring states occurs.Sent out when there is MDT measuring states in the UE for having set MDT measurement configuration informations During the UE of changing, base station will delete the corresponding MDT measurement configuration informations of UE that above-mentioned MDT measuring states change, and more The new UE current numbers that MDT measurement configuration informations have been set being locally stored.In order to ensure that base station obtains network communication quality Related data is more accurate and comprehensive, and base station can be according to following processes to the corresponding MDT measurements of UE in its compass of competency State enters Mobile state adjustment.
Step 210：When base station judges that the MDT measurement configuration statuses of any one cell are unrestricted to configure, and this is any one It is that a UE sets MDT measurement configuration informations when there is the UE for meeting default MDT configuration conditions in cell.
The corresponding MDT measuring states of the UE in any one cell that base station is administered to it enter the process bag of Mobile state adjustment Include, the UE to being not provided with MDT measurement configuration informations sets MDT measurement configuration informations, and deletes or reset and set The corresponding MDT measurement configuration informations of UE of MDT measurement configuration informations.
To be not provided with MDT measurement configuration informations UE set MDT measurement configuration informations process be：If base station judges any One MDT measurement configuration status of cell is unrestricted for configuration, and is not provided with MDT measurement configuration informations in any one cell UE meets default MDT configuration limits condition, then therefrom selecting one is not provided with the UE of MDT measurement configuration informations as first UE, and for a UE sets MDT measurement configuration informations；In selection course each time, surveyed when MDT is not provided with the presence of at least two When measuring the UE of configuration information, selection MDT measures allocation index highest UE as a UE, is that UE setting MDT measurements are matched somebody with somebody Confidence ceases.In the embodiment of the present invention, selection MDT measurement allocation index highests UE sets the specific mistake of MDT measurement configuration informations Cheng Wei：The maximum UE of regioselective ability parameter sets MDT measurement configuration informations；Now, if in the presence of at least two stationkeeping abilities Parameter identical UE, then select the maximum UE of location parameter to set MDT measurement configuration informations, and herein, location parameter maximum refers to Relative to having set the UE of MDT measurement configuration informations apart from the farthest UE for meeting MDT configuration conditions；If in the presence of at least two Parameter identical UE is put, then selects translational speed maximum UE that MDT measurement configuration informations are set；If in the presence of at least two movement speed Degree identical UE, then select the minimum UE of channel quality parameter to set MDT measurement configuration informations, to ensure that base station can accurately simultaneously And comprehensively obtain network of network coverage condition and communication quality position of problems.
The corresponding MDT measurement configuration informations states of UE in any one cell that above-mentioned base station is administered to it enter Mobile state During adjustment, default MDT configuration conditions refer to judge any one cell as configure it is unrestricted after, base station determine set When the current number for putting the UE of MDT measurement configuration informations is not up to default first threshold value, any one cell of its administration It is middle to there is the UE for meeting default MDT configuration limits condition, and the UE is the UE for being not provided with MDT measurement configuration informations.
In the embodiment of the present invention, when UE accesses current base station, i.e., can to base station report record measurement can with configured information, Record measurement can measure configuration parameter with the corresponding MDT of UE are carried in configured information, comprising TRSR and absolute time information etc.. Also, because formula MDT measurements immediately are only carried out in RRC connected states, RRC Idle state stops ongoing MDT surveys during switching Amount, therefore the new UE for accessing current base station is in the absence of the ongoing MDT of formula immediately measurements；And measured for recording MDT Continuous and effective (no matter UE is now in RRC connected states or RRC Idle state) within a period of time, therefore base station needs detection Whether whether the new UE for accessing also is carrying out recording MDT measurements (being the UE that is not provided with MDT measurement configuration informations).Now, Need to be judged with the information carried in instruction according to record measurement.Specifically decision process is：If record measurement is available There is no available MDT measurement result in configured information, then it represents that the UE is the UE for being not provided with MDT measurement configuration informations；Or, if Base station obtains the record measurement that the UE reports can be with, comprising available MDT measurement result, base station is according to the note in configured information Record measurement can detect that whether the corresponding MDT of the UE are measured by locally setting with the TRSR and absolute time information that are carried in configured information Put, if it is determined that the corresponding MDT measurement configuration informations of the UE are set for home base stations, and the configuration take-effective moment is measured according to MDT With MDT measurement configuration record duration (Logging Duration), judge that the UE had stopped before current time on MDT measurement, i.e. the UE is the UE for being not provided with MDT measurement configuration informations, then the UE matches somebody with somebody confidence for that can set MDT measurements Breath；Otherwise, then it represents that the UE is that cannot set MDT measurement configuration informations.
In the embodiment of the present invention, if it is determined that the MDT measurement configuration statuses of any one cell of base station administration are not received for configuration It is being each time that after UE sets MDT measurement configuration informations, all should judge to have set a UE of MDT measurement configuration informations after limit Current number whether reach default second threshold value, if reaching, terminate be UE set MDT measurement configuration informations；Or, The MDT measurement configuration statuses for judging any one cell of base station administration as configure it is unrestricted after, MDT measurements have been set with confidence The number of the first UE of breath is less than in default second threshold value, and any one cell of base station administration matches somebody with somebody in the absence of meeting MDT When putting the UE of condition, terminate to set MDT measurement configuration information processes for UE.When above-mentioned default second threshold value is current base station Quarter can at most set the number of the UE of MDT measurement configuration informations, be to be directed to the default parameter in each base station by OAM systems, Its numerical value is equal with default first threshold value.
Step 220：It is when base station judges that the MDT measurement configuration statuses of any one cell overload as configuration and above-mentioned any one When there is two UE for meeting default MDT regularization conditions in cell, the corresponding MDT measurements of the 2nd UE are deleted or reconfigured.
In order to the occupation condition of more neatly adjustment MDT measurements, in the embodiment of the present invention, base station is according to need Ongoing MDT measurements are actively discharged, that is, deletes or reconfigure the corresponding MDT measurements of the 2nd UE.
In the embodiment of the present invention, the corresponding MDT of UE for having set MDT measurement configuration informations are deleted or reset in base station The process of measurement configuration information is：If it is determined that the MDT measurement configuration statuses of any one cell of base station administration overload for configuration, and There is the UE that MDT measurement configuration informations have been set in any one cell, then can will meet default MDT regularization conditions The UE for having set MDT measurement configuration informations therefrom selects a UE for having set MDT measurement configuration informations as the 2nd UE, deletes Or reset the corresponding MDT measurement configuration informations of the 2nd UE；In selection course each time, meet when in the presence of at least two During the UE for having set MDT measurement configuration informations of default MDT regularization conditions, the minimum UE of selection MDT measurement allocation indexs makees It is the 2nd UE, deletes or reconfigure the corresponding MDT measurement configuration informations of the 2nd UE.
Further, the minimum UE of selection MDT measurements allocation index deletes or resets MDT surveys as the 2nd UE Measure configuration information detailed process be：The UE of regioselective ability parameter minimum (i.e. stationkeeping ability is worst) sets MDT measurements and matches somebody with somebody Confidence ceases；Now, if in the presence of at least two stationkeeping ability parameter identical UE, the minimum UE of selection location parameter sets MDT Measurement configuration information, herein, location parameter minimum refers to closest relative to the UE for having set MDT measurement configuration informations UE；If in the presence of at least two location parameter identical UE, the minimum UE of selection translational speed sets MDT measurement configuration informations； If in the presence of at least two translational speed identical UE, the maximum UE of selection channel quality parameter sets MDT measurement configuration informations.
Because MDT measurements include the measurements of formula MDT immediately and recording MDT measurements, for the measurements of formula MDT immediately, its initiation With terminate by current base station control, therefore, when the corresponding MDT measurement configuration informations of UE are set by current base station, then base station Measurement configuration information deletion can be measured to terminate this MDT measurements by deleting the corresponding MDT of the UE；And for recording MDT is measured, and base station cannot directly delete the corresponding MDT measurement configuration informations of UE of configured recording MDT measurement, but standard Regulation, if after base station sets new recording MDT measurement configuration informations for UE, UE is to abandon original recording MDT measurements to match somebody with somebody Confidence ceases and MDT measurement result, and performs MDT measurements according to the MDT measurement configuration informations for resetting, and therefore, it can pass through For the UE that recording MDT measurement configuration informations have been set in the cell of MDT configuration overloads resets the smaller MDT of resource occupation Measurement configuration information, to mitigate the resource occupation that MDT is caused.
In the embodiment of the present invention, base station receives the type of carrying MDT measurements in the MDT measurement initiation message that EM sends (i.e. Message is initiated in formula MDT measurements immediately or message is initiated in recording MDT measurements), for example, disappearing when for the initiation of formula MDT measurements immediately During breath, then only for the UE that MDT measurement configuration informations are formula MDT measurements immediately.
After base station receives the MDT of the formula immediately measurements that EM sends initiates message, selection MDT measurement configuration informations are formula immediately 2nd UE of MDT measurements carries out MDT measurement dynamic adjustment, if carried in the corresponding MDT measurement configuration informations of above-mentioned 2nd UE Report triggering mode meet it is default report trigger condition, then delete the corresponding MDT measurement configuration informations of the 2nd UE.Wherein, What is carried in the corresponding MDT measurement configuration informations of two UE reports triggering mode to meet default to report the trigger condition to refer to：If the In the corresponding MDT measurement configuration informations of two UE carry report triggering mode for A2 (Event A2for LTE) event trigger or Person A2 (A2event triggered periodic for LTE) event triggers periodic report or 1F (Event 1F for UMTS) event triggering, or 1I (Event 1I for UMTS 1.28Mcps TDD) event triggering, or above-mentioned report triggering Mode is unlimited for periodicity is reported and reports number of times, then turn when the 2nd UE is no after MDT measurement configuration informations are set Enter RRC (Radio Resource Control；Wireless heterogeneous networks) Idle state or when being switched to other cells, believed by RRC The corresponding MDT measurement configuration informations of the 2nd UE are deleted in order；Or, if reporting in the corresponding MDT measurement configuration informations of the 2nd UE Triggering mode is not unlimited for periodicity is reported and reports number of times, then when the 2nd UE is not transferred to RRC after MDT measurements are set Idle state is switched to other cells, and measures configuration take-effective moment, reporting time in MDT measurement configuration informations according to MDT Number and when reporting the UE of interval acquiring the 2nd to carry out MDT and measure, deletes the corresponding MDT of the 2nd UE and measures by RRC signaling Configuration information.
After base station receives the recording MDT measurement initiation message that EM sends, selection MDT measurement configuration informations are recording 2nd UE of MDT measurements carries out MDT measurement dynamic adjustment, if above-mentioned 2nd UE correspondence MDT measurement residual time lengths are more than default note Duration is recorded, and the 2nd UE is not transferred to RRC Idle state or is switched to other cells after MDT measurement configuration informations are set, Then reset the corresponding MDT measurement configuration informations of the 2nd UE.In the embodiment of the present invention, recording MDT measures corresponding measurement Minimum 600 seconds of time duration, i.e., above-mentioned preset recording duration is 600s, therefore, if it is determined that certain has set MDT The corresponding measurement residual time lengths of UE of measurement configuration information are less than 600 seconds, then again for the UE sets recording MDT measurement configurations Information may heavy system burden, i.e., only for MDT measurement residual time lengths more than default record duration threshold value UE resets MDT measurement configuration informations.Its specific method is：Set in any one cell for obtaining current base station administration MDT measurement configuration informations, and RRC Idle state is not transferred to after MDT measurement configuration informations are set or to be switched to other small 2nd UE in area, by contrasting, MDT measures the configuration take-effective moment and MDT measures configuration record duration, is calculated from current time Remaining twoth UE of the duration more than 600 seconds of MDT measurements for rising is the 2nd UE of reconfigurable MDT measurement configuration informations.
