The target of MDT measurements is to provide data analysis network performance.MDT measures the key for finding influence network performance
Link, to determine whether necessary adjustment network configuration parameters or carry out the network capacity extension.In network early deployment or big rule
Mould in use, the function can be used for detect UE service quality experience (Quality of experience, referred to as
QoE the requirement of the network planning) whether is met.Existing artificial drive test equally has a function of measurement, but the cost of artificial drive test compared with
Height, and some specific regions can not fully be measured using artificial drive test.Therefore MDT measurements use certain amount
UE report using measured data during business, the measurement data of statistical significance is provided for operator.
For MDT user, that is, for operator, this measurement result, which is associated with positional information, just more reality
Border meaning, if measurement result shows that existing capacity can not meet throughput requirement, operator can contemplate on particular location
Deployment small base station with solve the problems, such as user service impression it is bad, but if above-mentioned network side measurement result can not and position
Together, operator then needs just to can determine that the positional information of installation small base station by artificial drive test information association.Therefore have
Necessity provides the positional information of network side MDT measurement result.
Current position information generally all produces in end, and the positional information can be terminal because the needs of other business
And caused available position information, given the correct time on MDT measurements are carried out, if there is such positional information end side, it is possible to take
Bring network.But often end side is without such available position information.In order to solve this problem, existing scheme proposes
It is a kind of to trigger the method for obtaining positional information, that is, actively triggering when MDT measurement reports are reported of network requirement terminal
Obtain positional information.
In the prior art, the minimum road measuring method of triggering acquisition positional information can bring extra electric power to disappear to terminal
Consumption, and it is well known that terminal-pair power consumption is extremely sensitive, because this will have a strong impact on use feeling of the user to terminal.For
Do not consume more electric energy and abandon using triggering obtain that positional information can only largely rely on existing subscriber can
With positional information, such scheme considerably reduces the reliability of positional information acquisition, because the terminal under many scenes can not
Effective positional information is provided, causes the validity for minimizing drive test information to reduce.But in turn if obtained using triggering
The problem of minimum road measuring method of positional information will bring terminal to consume energy.

Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, below in conjunction with accompanying drawing to the present invention
Embodiment be described in detail.It should be noted that in the case where not conflicting, in the embodiment and embodiment in the application
Feature can mutually be combined.
In the present embodiment, mainly included the following steps that as shown in figure 1, minimizing road measuring method：
During MDT, node receives MDT configuration information, wherein the measurement for including triggering acquisition positional information will
Ask；
The number that node obtains positional information to triggering according to being locally configured optimizes limitation.
Wherein, above-mentioned node can include but is not limited to one below：Terminal or access network elements, such as：UE、eNB、
RNC etc..
Preferably, if node is access network elements, node can continue the MDT for having already passed through limitation optimization matching somebody with somebody confidence
Breath and/or optimization instruction are sent to terminal.
Preferably, if node is terminal device, terminal checks that MDT configuration information is before MDT measurement configurations are performed
It is no to optimize by limitation, to determine how to perform MDT measurements.
The above method is applied to E-UTRAN and UTRAN systems, and road is minimized suitable for minimizing drive test and record immediately
Survey, be also applied to the MDT based on the management and MDT based on signaling.
The MDT based on the signaling and MDT based on management is combined separately below, and based on minimum drive test immediately or is based on
The minimum drive test of record, above-described embodiment process is further described with four application examples.
Using example one
This application example is used to illustrate network side by directly changing MDT configuration information so as to which immediate constraint terminal is actively touched
Hair obtains the minimum road measuring method of positional information.
As shown in Fig. 2 this method can include following processing step：
Step S101：Network management system (network Element Management System, referred to as EMS) triggers most
Smallization drive test, send carry minimize drive test configuration information first message (such as TraceSession Activation disappear
Breath) give HSS network element；Wherein, the measurement request of positional information is obtained in the configuration information comprising triggering；
Step S102：Location register (HSS) retrieves UE into after attachment state, and transmission, which carries, to be minimized drive test and match somebody with somebody
Second message of confidence breath is to the core network element where UE；Wherein, positional information is obtained comprising triggering in the configuration information
Measurement request；
If under E-UTRAN network conditions, core network element MME；If UTRAN network conditions, core net net
Member is SGSN either MSC server.When core network element is MME, the second message can be Update location
answer。
Step S103：Core network element sends the 3rd message for carrying above-mentioned minimum drive test configuration information to access network
Network element；
Under E-UTRAN network conditions, access network elements eNB, above-mentioned 3rd message can be Initial context
Setup request (initial context sets request) message；If UTRAN ps domains, access network elements RNC, then the 3rd
Message can be CN invoke Trace (core net triggering tracking) message；Certainly, it is newly-increased can also to send one for core network element
Special message；
Step S104：Access network elements optimize limitation to the minimum drive test configuration information received, then will be excellent
Minimum drive test configuration information after change is sent to UE；
Specifically, access network elements such as identify that wherein including triggering obtains position after MDT configuration information is received
The measurement request of information, then further check whether to need to optimize the MDT measurable amounts included in the MDT configuration information
Limitation；
Assuming that using drive test pattern is minimized immediately in this example, base station needs to check the above-mentioned MDT configuration information received
The measurement type of middle instruction is periodic type or event trigger type.
If it is judged that instruction is periodic type, base station needs to check the above-mentioned MDT configuration information middle finger received
Whether the measurement interval (Report interval) and pendulous frequency (Report amount) shown meet that economize on electricity requires.
As being less than pre-configured interval threshold when the value for judging measurement interval, then base station needs to increase the length of measurement interval
Degree, the elongation at interval is helpful for saving power for terminal, therefore base station can accordingly increase what is indicated in above-mentioned MDT configuration information
The value of measurement interval, such as double.
In the prior art, pendulous frequency be configurable to 1 time, 2 times, 4 times, 8 times, 16 times, 32 times, 64 times or it is infinite repeatedly
(infinity).Such as pendulous frequency is configured to infinity, that is, during drive test is minimized immediately it is one straight
Row measurement.Base station receive after the MDT configuration information of such type, it is necessary to by pendulous frequency be optimized for it is limited repeatedly, such as basis
Pendulous frequency is revised as 32 times or 64 times by configuration；If the pendulous frequency indicated in MDT configuration information is 64 times, base station warp
Cross and judge that the measurement needs terminal actively to trigger and obtains positional information, pendulous frequency can excessively consume the electric energy of terminal, then base station
The pendulous frequency indicated in MDT configuration information can also be revised as by 32 times or less number according to configuration.
In specific implementation, a pendulous frequency upper limit, such as 32 times can be pre-configured with base station side.Received in base station
After the MDT configuration information for obtaining positional information requirement is triggered comprising active, the pendulous frequency indicated in the MDT configuration information is entered
Row checks, it is found that the pendulous frequency of instruction is more than the pendulous frequency upper limit, is such as infinite multiple (infinity), then base station can be with
The pendulous frequency is revised as 32 times according to the pendulous frequency upper limit being pre-configured with.
Closer, base station can be combined with measurement of the situation of movement of terminal to being indicated in above-mentioned MDT configuration information
Number is limited, if the pendulous frequency indicated in the MDT configuration information that base station is judged to carry is more than on the pendulous frequency
Limit, then the situation of movement of terminal can be obtained from the user history information (UE history) of terminal, if terminal movement speed
Spend at high speed, base station can not change the value, if moving velocity of terminal is low velocity, base station then can be according to being pre-configured with
The pendulous frequency upper limit pendulous frequency indicated in MDT configuration information is modified.
Base station is to use the message related to RRM measurement to the minimum drive test configuration information that terminal is sent
Carry, specifically, in the lte networks, can be disappeared by RRCConnectionReconfiguration (RRC connections reconfigure)
Breath carries the minimum drive test configuration information by optimization.
Step S105：UE receive minimize drive test configuration information after measured according to the parameter after optimization and on
Report.
Because UE is not aware that configuration has already been through optimization, thus can according to the measurement interval that is indicated in configuration information and
Pendulous frequency is measured and reported.Because the measurement minimized comprising triggering acquisition positional information in drive test configuration information will
Ask, thus UE in reporting measurement reports, it is necessary to carry available positional information, if without available positional information, UE will
Open its positional information equipment (such as：GPS (Global Positioning System, global positioning system) equipment or positioning
System (LocationService, referred to as LCS)) equipment etc. to be to obtain positional information.
In the case of further optimization, UE can check the configuration information after minimum drive test configuration information is received
Optimization whether is had been subjected to, such as checks whether the pendulous frequency indicated in the configuration information is countless, is judging it is infinite
In the case of secondary, UE can select not supporting infinite repeatedly triggering to obtain positional information, i.e. UE, which can select not trigger, obtains position
Confidence ceases or only triggered the acquisition of limited repeatedly positional information..
Using example two
This application example is used to illustrate terminal with the help of no network side, and initiative recognition and optimization triggering obtain position
The method of information.
As shown in figure 3, this method can include following processing step：
Step S201：EMS triggerings minimize drive test, and MDT configuration information is sent into access network elements by southbound interface
(such as eNB or RNC)；Wherein, the measurement request that triggering obtains positional information is contained in the configuration information；
Step S202：Access network elements select suitable terminal, and send MDT configuration information to selected terminal, its
In, the measurement request that triggering obtains positional information is contained in the MDT configuration information.This application example is the MDT based on management,
Therefore one or more suitable terminal may be selected in access network elements eNB or RNC；Access network elements can pass through existing message
Above-mentioned MDT configuration information is sent to the selected terminal, such as in E-UTRAN networks, the message can be
Loggedmeasurements configuration (record measurement configuration) message.
Step S203：The MDT configuration information that end-on receives optimizes limitation, and is configured according to the MDT after optimization
The acquisition of information execution position information.
Such as in E-UTRAN systems, UE checks that pendulous frequency configuration therein is after MDT configuration information is received
It is no reasonable.By pendulous frequency can derive once minimize drive test during overall measurement number (the two value is equal, that is, surveys
Amount number as once minimizes the overall measurement number during drive test), it is default total to judge whether the overall measurement number is more than
Pendulous frequency higher limit, if it is, UE can further optimize, such as increase interval time of measurement, actively triggered with reducing
Obtain the number of positional information.It should be strongly noted that UE optimizations is actively to trigger the number for obtaining positional information, UE's
The record of MDT measurement result and reporting is carried out still according to the measurement period and measurement interval that are indicated in MDT configuration information, also
It is that the optimization process for saying this example has no effect on the implementation of terminal MDT measurement process.
Optimization, UE can also be only in the acquisition of partial period active trigger position information, such as only in measurement period
Before, in or the later stage perform active obtaining positional information.As an example it is assumed that the measurement period indicated in MDT configuration information is 2 small
When, measurement interval is 10 minutes, then overall measurement number is 12 times.Assuming that this value is higher than default overall measurement number higher limit,
Then this example can allow UE actively to trigger acquisition positional information only within first hour, that is, carry out 6 times.
Or UE can also be evenly distributed the opportunity that actively triggering obtains positional information, it is assumed for example that in MDT configuration information
The measurement period of instruction is 2 hours, and measurement interval is 10 minutes, then overall measurement number is 12 times, it is assumed that this value is higher than default
Overall measurement number higher limit, then this example can allow UE every one-shot measurement process actively triggering once obtain position letter
Breath.
Or, UE can also actively triggering obtains positional information according to the situation of movement of oneself, it is assumed for example that MDT is configured again
The measurement period indicated in information is 2 hours, and measurement interval is 10 minutes, then overall measurement number is 12 times.Assuming that this value is high
In default overall measurement number higher limit, then when each measurement period arrives, as UE detects its velocity factor
(speed factor) is shown as high-speed mobile, then this example allows UE actively triggering acquisition positional informations；As UE detects it
Velocity factor (speedfactor) is shown as low speed or static, then now actively triggering does not obtain position to UE to the permission of this example
Information.
In the case of further optimization, UE is after it have modified MDT configuration information, the active trigger position that will finally configure
Access network elements are supplied in the number write-in measurement report of information.
In addition, actively triggering acquisition positional information can be realized UE by opening its positional information equipment, such as GPS device
Or LCS equipment etc..
Using example three
This application example is used for explanation in the case of drive test is minimized immediately, and terminal is how to optimize actively to obtain position letter
Breath.
As shown in figure 3, this method can include following processing step：
Step S301：EMS triggerings minimize drive test, and MDT configuration information is sent into access network elements by southbound interface
(such as eNB or RNC)；Wherein, the measurement request that triggering obtains positional information is contained in the configuration information；
Step S302：Access network elements select suitable terminal, and send MDT and be allocated to selected terminal, wherein, should
The measurement request that triggering obtains positional information is contained in MDT configuration information.This application example is the MDT based on management, access
One or more suitable terminal may be selected in network element eNB or RNC；Access network elements can will be above-mentioned by existing message
MDT configuration information is sent to the selected terminal of terminal, and the message, which can be, to be used and the related identical of RRM measurement
Message, specifically, in the lte networks, the message can be RRCConnectionReconfiguration message.
Step S303：The MDT configuration information that end-on receives optimizes limitation, and is configured according to the MDT after optimization
The acquisition of information execution position information.
Such as in E-UTRAN systems, UE such as checks that the above-mentioned MDT received matches somebody with somebody after MDT configuration information is received
The measurement type indicated in confidence breath is periodic measurement such case, then determines whether report amount and report
Whether interval configurations are reasonable.The overall measurement once minimized during drive test can be such as derived by above-mentioned pendulous frequency
Number, judges whether the overall measurement number is more than default overall measurement number higher limit, if it is, UE can be further excellent
Change, such as increase interval time of measurement, to reduce the number that actively triggering obtains positional information.It should be strongly noted that UE
Optimization be actively triggering obtain positional information number, the record of UE MDT measurement result and report still according to MDT configure
The measurement period and measurement interval indicated in information is carried out, that is to say, that the optimization process of this example has no effect on terminal MDT surveys
The implementation of amount process.
Optimization, UE can also be only in the acquisition of partial period active trigger position information, such as in overall measurement number
(report amount) be 32 times, more than the overall measurement number higher limit set in the case of, then this example can allow UE to select
Preceding 16 actives triggering obtains positional information, and latter 16 times actively triggering does not obtain positional information.
Or UE can actively triggering obtains opportunity of positional information with mean allocation, it is assumed for example that overall measurement number is
16 times, then when the overall measurement number is more than default overall measurement number higher limit, this example allows UE to be measured every a MDT
Process just actively triggers and once obtains positional information.
Or, UE can also actively triggering obtains positional information according to the situation of movement of oneself, it is assumed for example that MDT is measured again
Overall measurement number be 10 times, it is assumed that this value be higher than default overall measurement number higher limit, then each cycle arrival when
Wait, as UE detects that its velocity factor (speed factor) is shown as high-speed mobile, then this example allows UE actively triggering obtains
Take positional information；As UE detects that its velocity factor (speed factor) is shown as low speed or static, then this example allows
Actively triggering does not obtain positional information to UE.
In the case of further optimization, UE is after it have modified configuration measurement, the active trigger bit confidence that will finally configure
Access network elements are supplied in the number write-in measurement report of breath.
In addition, actively triggering acquisition positional information can be realized UE by opening its positional information equipment, such as GPS is set
It is standby, such as LCS equipment etc.
Using example four
This application example is used to illustrate to optimize configuration by network side, and explicit instruction terminal performs follow-up MDT measurements
Process.
As shown in figure 4, this method can include following processing step：
Step S401：EMS triggerings minimize drive test, and MDT configuration information is sent into access network elements by southbound interface
(such as eNB or RNC)；Wherein, the measurement request that triggering obtains positional information is contained in the configuration information；
Step S402：Access network elements select suitable terminal, and limitation is optimized to the MDT configuration information received
Afterwards, the MDT configuration information after optimization and optimization instruction are sent to selected terminal：Wherein, after optimization in MDT configuration information
The measurement request of positional information is still obtained comprising triggering.This application example is the MDT based on management, access network elements eNB or
Person RNC can select one or more suitable terminal；Access network elements can be configured the MDT after optimization by existing message
Information is sent to selected terminal.
Specifically, access network elements, that is, base station are such as identified wherein comprising tactile after MDT configuration information is received
Hair obtains the measurement request of positional information, then further checks whether to need to optimize limitation MDT measurable amounts.
Using drive test pattern is minimized immediately in this example, base station needs to check the above-mentioned MDT configuration information middle finger received
The measurement type shown is periodic type or event trigger type.
If it is judged that being periodic type, then base station needs to check what is indicated in the above-mentioned MDT configuration information received
Whether measurement interval and pendulous frequency meet that economize on electricity requires.
As being less than pre-configured interval threshold when the value for judging measurement interval, then base station needs to increase the length of measurement interval
Degree, the elongation at interval are helpful for saving power for terminal；Because terminal can actively trigger according to the identical cycle in default situations
Obtain the measurement of positional information and relevant information, therefore base station can accordingly increase actively triggering and obtain between the measurement of positional information
Every, such as double, the number of terminal active triggering acquisition positional information is reduced with this.
In the prior art, pendulous frequency be configurable to 1 time, 2 times, 4 times, 8 times, 16 times, 32 times, 64 times or it is infinite repeatedly
(infinity), such as pendulous frequency is configured to infinity, that is, during drive test is minimized immediately it is one straight
Row measurement.Base station receives after the MDT configuration information of such type and is optimized for, it is necessary to which active is triggered and obtains the number of positional information
It is limited multiple, such as be limited to the number of active triggering acquisition positional information 32 times or 64 times according to configuration；If MDT matches somebody with somebody
The pendulous frequency indicated in confidence breath is 64 times, and base station obtains positional information by judging that the measurement needs terminal actively to trigger,
Pendulous frequency can excessively consume the electric energy of terminal, then base station can also trigger active according to configuration the number for obtaining positional information
It is revised as 32 times or less secondary.
Unlike application example 1, using the pendulous frequency indicated in example 4 and unmodified MDT metrical informations, but
Optimization limits terminal and actively triggers the number for obtaining positional information.Therefore confidence after processing is completed, is matched somebody with somebody in base station in original MDT
In the content basis of breath, the number limitation that the triggering after optimization obtains positional information is also add, number limitation can be one
Individual optimization instruction parameter, such as how much indicate measurement interval increase, or indicate it is how many etc. that pendulous frequency is limited to.
Base station is to use the message related to RRM measurement to the minimum drive test configuration information that terminal is sent
Carry, specifically, in the lte networks, MDT can be carried by RRCConnectionReconfiguration message and match somebody with somebody confidence
Breath and optimization instruction parameter.
Step S403：Terminal upon receipt, measures according to the MDT configuration information received, and is indicated according to optimization
The active triggering that parameter carries out finite number of time obtains positional information.
This application example is to minimize drive test immediately, such as in E-UTRAN systems, UE is after MDT configuration information is received
Check for optimization instruction parameter.If any, then terminal can indicate that parameter carries out active obtaining position according to the optimization
The operation of confidence breath.
Such as the pendulous frequency indicated in MDT configuration information is 64 times, and optimize the acquisition position letter of instruction parameter request
The number of breath is 32 times, then UE can be in measurement period first 32 times are actively triggered to obtain positional information.
If the interval for optimizing the acquisition positional information of instruction is twice of the measurement interval indicated in MDT configuration information,
Then UE can actively triggering once obtains positional information after a MDT measurement.
In the case of further optimization, if network side does not issue optimization instruction parameter, UE should check report
Whether amount and report interval configurations are reasonable, can such as be derived by above-mentioned pendulous frequency and once minimize road
Overall measurement number during survey, judges whether the overall measurement number is more than default overall measurement number higher limit, if it is,
UE can further optimize, such as increase interval time of measurement, to reduce the number of active trigger position information.Need especially to say
Bright, what UE optimized is the number of active trigger position information, and UE MDT is measured and reported configures message still according to MDT
The measurement period and measurement interval of middle instruction are carried out, that is to say, that the optimization process of this example has no effect on terminal MDT measurements
Implement.
