Description
Technical field
The present invention relates to a kind of minimum road measuring method in the communications field, more particularly to wireless communication system and realize the party
The terminal of method.
Background technology
The cost and complexity of artificial drive test, third generation partnership meter are carried out to reduce operator using special equipment
Draw (3GPP, Third Generation Partnership Projects) universal land radio access web (UTRAN,
Universal Terrestrial Radio Access Network, including base station NodeB and radio network controller (RNC))
With universal land radio access web (E-UTRAN, Evolved Universal Terrestrial the Radio Access of evolution
Network, including evolution base station eNB) system version 10 (Release-10) start introduce minimize drive test (MDT,
Minimization of Drive Test) function.Core net corresponding to UTRAN (CN, Core Network) is used including host
Family server (location register (HSS), Home Subscriber Server), Mobile Switching Center Server (MSC
Server, Mobile Switching Centre Server), service GPRS Support Node (SGSN, Serving GPRS
Support Node, GPRS-General Packet Radio Service- GPRSs) etc..E-UTRAN pairs
The core net CN answered includes host-user server location register (HSS), mobile management entity (MME, Mobile
Management Entity) etc..Minimize drive test function and utilize user equipment (UE, User Equipment, or be terminal)
Automatic collection metrical information is reported by chain of command (Control Plane) signaling gives wireless access network (RAN, Radio
Access Network, refer to RNC for UTRAN systems, refer to eNB for E-UTRAN systems), then reported by wireless access network
Entity (TCE, Trace are collected in tracking to Operation ＆ Maintenance System (OAM, Operation And Maintenance)
Collection Entity), for the network optimization, such as find and solve the problems, such as the network coverage.
MDT functions are divided into the MDT (Management based MDT) based on the management and MDT based on signaling
(Signaling based MDT).The activation of MDT based on management is typically (by taking E-UTRAN systems as an example, below
OAM (Operation and Maintenance or network management system) sends tracking activate message (the Trace session for including MDT configurations together)
Activation eNB, eNB suitable UE of selection in region (Area) as defined in the message) are given, and the MDT is matched somebody with somebody into confidence
Breath is sent to the UE chosen.The activation of MDT based on signaling is that the tracking activate message for including MDT configurations is sent by OAM
(Trace session activation) is specified to location register (HSS) (Home Subscriber Server) with activating
The MDT configuration information of the UE is sent to MME by UE MDT measurements, location register (HSS), and MME configures the MDT of the UE
Information is sent to eNB, and most MDT configuration information is sent to UE to eNB at last.MDT based on signaling is generally with international mobile subscriber mark
Know (IMSI, International Mobile Subscriber Identity) or international mobile station device identification (IMEI,
International Mobile Station Equipment Identity) specify some UE, or plus area information with
Limit UE selection.The track reference from OAM is included in MDT based on management and the tracking activate message based on signaling
(Trace Reference) information, including public land mobile network (Public Land Mobile Network,
PLMN) information, by Mobile Country Code MCC (Mobile country code, MCC) and Mobile Network Code (Mobile Network
Code, MNC) composition.
MDT functions are operated in Idle state and are operated in connected state according to it can be divided into two kinds of mode of operations, be specially " note
Record minimizes drive test (Logged MDT) " and " minimizing drive test (Immediate MDT) immediately ".Record minimizes drive test and refers to UE
(refer to RRC_IDLE states for E-UTRAN systems in wireless heterogeneous networks idle condition；Also include cell for UTRAN systems
PCH state (CELL_PCH) and UTRAN Acceditation Area PCH states (utran registration area_paging indicator channel)), when the condition configured meets
When collect and store correlation measurement information and be used to report when receiving wireless access network (RAN) order request in the future, wireless access network
(RAN) after receiving the data, collect or be directly forwarded to TCE.Drive test is minimized immediately refers to UE in wireless heterogeneous networks
Connection status (refers to RRC_CONNECTED states for E-UTRAN systems；Refer to cell dedicated channel status for UTRAN systems
(CELL_DCH) correlation measurement information is collected when) and active upload gives wireless access network (RAN) when report meets report condition,
After wireless access network (RAN) receives report, collect or report is directly passed into TCE.
The measurement for minimizing drive test immediately has M1 and M2 to measure two kinds in E-UTRAN measurement at present, and E-UTRAN M1 is
UE according to 36.214 agreements requirement measuring reference signals receiving power (RSRP, Reference Signal Received
Power) and Reference Signal Received Quality (RSRQ, Reference Signal Received Quality), the measurement can be
Periodic measurement or event triggering measurement, E-UTRAN M2 measurements be according to 36.213 protocol measure power levels (PH,
Power Headroom)；There is M1 in UTRAN sides at present, M2, M3 measurement, UTRAN M1 measurements are according to 25.215 protocol measures
It can be periodic measurement to receive parameter, the measurements such as reference code power (RSCP, Received Signal Code Power)
Or event triggering measurement；UTRAN M2 measurements are to measure to receive the parameters such as reference code power, the measurement according to agreement 25.255
Can be periodic measurement or event triggering measurement；UTRAN M3 measurements are to test signal to noise ratio (SIR) according to agreement 25.255
Etc. parameter.
The target of MDT QoS (Quality of Service, service quality) measurements is to provide data analysis network performance.
MDT QoS measure the key link for finding to influence network performance, discover whether to be necessary to adjust network configuration parameters or
Person's network capacity extension.In network early deployment or large-scale use, the function can be used for detecting UE service quality sense
Whether met the requirement of the network planning by (QoE, Quality of experience).Existing artificial drive test equally has QoS measurements
Work, but the cost of artificial drive test is higher, and some specific regions can not fully be measured using artificial drive test.
Therefore MDT QoS measurements are reported using a number of UE is measured using QoS during business, and statistical significance is provided with for operator
Measurement data.
The method of MDT QoS measurements is based on the method that existing layer two measures (Layer2 measurements).Existing layer two
Measure and provided in agreement 36.314, the data of some performances for providing the concern of webmaster side, such as packet message throughput
The measurement items such as (IP Throughput), message delay (packet delay), packet loss (Data Loss).These measurements exist
ENB sides perform, and UE is simultaneously not involved in actual measurement.
In the prior art for example in E-UTRAN networks, eNB, which can realize, to be measured the layer two of particular UE, can be based on this
MDT QoS measurements, such as throughput (Throughput) measurement etc. are carried out, for operator, this measurement result is associated with
More specific location information is just more of practical significance, and MDT more specific location information comprises at least latitude and longitude information in the prior art, may be used also
With including information such as height；If measurement result shows that existing capacity can not meet throughput requirement, operator can contemplate
On particular location dispose small base station to solve user service impression, if the network side measurement result can not and particular location
Together, operator then needs just to can determine that the more specific location information of installation small base station by artificial drive test information association.Cause
This is necessary the more specific location information for providing network side MDT QoS measurement results.
Access network relies on the positional information that terminal provides in disclosed technology, has two kinds of main offers in public technology
Mode, a kind of mode are terminals when each cycle is recorded or reported, there is provided available positional information at that time, another kind side
Formula is that actively triggering obtains positional information and is supplied to network the requirement of terminal accessed network.No matter which kind of mode, terminal providing

Embodiment
In order to ensure that network side on the premise of its normal MDT measurement result can associate more specific location information, avoids end
End provides inoperative position information, it is therefore desirable to which terminal further checks the reason for inoperative position information triggering.According to prior art,
Network side is that MDT measurement objects configuration MDT and MDT measurement object business actual conditions are to separate, that is, MDT configuration distributings
When, measurement object is uncontrollable with the presence or absence of business network side, and terminal constantly provides after this has resulted in configuration distributing
Positional information, and some positional informations are to the completely useless place of network side.Therefore in this case, if terminal can identify
The scene of invalid measurement simultaneously avoids providing positional information under invalid situation, it is possible to reaches and saves interface-free resources and terminal electric energy
Purpose.
Provided herein is following methods：
After terminal receives MDT configuration information, judge whether MDT measurement objects meet relative position information requirements, terminal is only
When judging that MDT measurement objects meet relative position information requirements, the positional information of this terminal is provided to network side.
Above-mentioned MDT measurement objects refer to that the MDT of network side progress MDT measurements in the MDT configuration information that terminal receives is surveyed
Object is measured, including at least the object of measurement, such as throughput (Throughput) or data volume (data volume) etc..It is optional
Ground, business information can also be included, configured by MDT configuration information, for indicating the industry corresponding to this MDT measurement object
Business, can be indicated by traffic direction and/or type of service.If, can without business information is not included in MDT measurement objects
It is defaulted as being to be directed to all business.Such as it can indicate to be uplink service in configuration and/or be downlink business；In addition in configuring also
Can indicate be certain quality of service type mark (QCI, QoS Class Identifier) business either all classes of terminal
The business of type.Illustrated by taking throughput as an example, if being designated as uplink service in MDT configurations, MDT measurement objects are up
The throughput of business, in addition if MDT configurations further indicates certain QCI business, then MDT measurement objects are certain QCI uplink service
Throughput.
Relative position information requires to include time requirement and business need, only all meets in time requirement and business need
When, just it is considered to meet relative position information requirements, either condition is unsatisfactory for, then it is assumed that be unsatisfactory for relative position information requirements.
Checking process is as follows：
Terminal judges locally whether preserve positional information, whether has positional information additional symbols below according to local：
If terminal local preserves positional information (other business that the positional information possibly relies on terminal obtain), sentence
Break the positional information whether before the deadline, if not before the deadline, then it is assumed that be unsatisfactory for time requirement, terminal will not report
Positional information, if before the deadline, further determining whether to meet business need, that is, judging in the effective of the positional information
In phase, whether the portfolio of business corresponding to MDT measurement objects exceedes predetermined threshold value, if not less than, then it is assumed that it is unsatisfactory for industry
Business requires, terminal not reporting position information, if it does, now time requirement and business need are satisfied by, then terminal is to network
Side provides the positional information of this terminal；
Judge whether positional information includes before the deadline：Judge current time whether the positional information the term of validity
It is interior, or judge the time (time for providing positional information to network side) of reporting measurement reports whether in the positional information
In the term of validity.The purpose of judgement be to ensure that to network side provide positional information when terminal positional information it is still effective, i.e., on
The positional information for offering network side is effective.Due to current time and the difference very little that above calls time, so when judging current
Between scheme it is also feasible.
If the non-save location information of terminal local, (now positional information is effective for the term of validity for judging in positional information
Phase includes the one section of valid interval recalled forward from current time) in, whether the portfolio of business corresponding to MDT measurement objects
More than predetermined threshold value, if not less than, then it is assumed that it is unsatisfactory for business need, terminal not reporting position information, if it does, then eventually
End triggering obtains positional information (random time that can be when being obtained at the end of measurement period or aperiodicity measures obtains),
And the positional information of this terminal is provided to network side.The judgement of time conditions can be omitted under such a scene.
In the case where terminal local preserves positional information, during the acquisition of the term of validity=positional information of positional information
Between ± positional information valid interval.In the case where terminal local does not preserve positional information, the term of validity of positional information=
The valid interval of m- positional information during the acquisition of the positional information.Valid interval can use prior art value or enter as needed
Row setting.
The judgement of business need is exemplified below, such as MDT measurement objects are throughput (Throughput) measurements, it is false
If the threshold value of pre-set business amount is 0, then if in the positional information term of validity throughput more than zero if it is considered that meet business
It is required that.Such as MDT measurement objects are data volume (data volumn) measurements again, it is assumed that predetermined threshold value is 10 kilobytes (10k
Byte) (threshold value can also be zero or other numerical value, herein by way of example only), then if in the positional information term of validity number
Exceed the threshold value according to amount, then it is assumed that meet business need.
The terminal of the above method is realized, as shown in figure 1, including receiving module, module and reporting module are checked, wherein：
The receiving module, for receiving MDT configuration information；
The inspection module, for checking whether MDT measurement objects meet the requirement of relative position information；
The reporting module, for it is described inspection module judge that MDT measurement objects meet relative position information requirements when, to
Network side provides the positional information of this terminal.
Above-mentioned relative position information requires to include time requirement and business need, when time requirement and business need are full
When sufficient, it is believed that meet relative position information requirements.Specifically, time requirement is included to terminal during network side offer positional information
Positional information is still effective；Business need is included in the business of business corresponding to MDT measurement objects in the term of validity of positional information
Amount exceedes predetermined threshold value.
Preferably, the terminal also includes logging modle, for preserving the positional information of the terminal；
When the inspection module preserves the positional information of the terminal in logging modle, MDT is checked in the following ways
Whether measurement object meets relative position information requirements：Whether before the deadline the positional information is judged, if not effective
In phase, then inspection result is is unsatisfactory for relative position information requirements, if before the deadline, judged in the positional information
In the term of validity, whether the portfolio of business corresponding to MDT measurement objects exceedes predetermined threshold value, if not less than inspection result
To be unsatisfactory for relative position information requirements, if it does, then inspection result is to meet relative position information requirements.Positional information
The valid interval of the acquisition time ± positional information of the term of validity=positional information.
Preferably, terminal also includes position information acquisition module, in the inspection module triggering, obtaining terminal
Positional information；When checking that module does not preserve the positional information of the terminal in the logging modle, examine in the following ways
Look into whether MDT measurement objects meet relative position information requirements：The term of validity of positional information is determined, is judged in the term of validity,
Whether the portfolio of business corresponding to MDT measurement objects exceedes predetermined threshold value, if not less than inspection result is to be unsatisfactory for closing
Join positional information requirement, if it does, then inspection result is to meet relative position information requirements, trigger position acquisition module.Position
The valid interval of m- positional information during the acquisition of the term of validity=positional information of confidence breath.
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.
Embodiment one
This example explanation is based on signaling MDT, immediately under MDT scenes, and actively triggering obtains positional information and judged and is terminal
The no process reported.As shown in Fig. 2 this method includes following steps：
Step 101：Network management system (EMS) triggering minimizes drive test, sends and minimizes drive test configuration message such as Trace
Session Activation message gives location register (HSS) network element, and MDTQoS measurement requests are included in the message；
Step 102：Location register (HSS) is retrieved after UE is in attachment state, is sent and is minimized drive test configuration message
To the core network element where UE, MDT QoS measurement requests are included in the message；
If under E-UTRAN network conditions, the core network element is MME；If UTRAN network conditions, the core
Heart network element is SGSN either MSC server.Such as core network element, when being MME, the message for carrying MDT configurations is more new position
Response (update location answer).
Step 103：Core network element, which is sent, minimizes drive test configuration message to access network element, and MDT QoS are included in the message
Measurement request；
If under E-UTRAN network conditions, the access network element is eNB, if UTRAN networks, the access network
Member is RNC.
If in the case of E-UTRAN networks, the minimum drive test configuration message of carrying can build for initial context
Vertical (Initial context setup request) message, if UTRAN ps domains, the minimum drive test configuration of carrying disappears
Cease and trigger tracking (CN invoke Trace) message for core net.
Step 104：Access network receives the minimum drive test configuration message that core network element sends signaling MDT, to the UE
MDT QoS business measure；
Access network element, which starts, to be measured the QoS of the UE.Such as in E-UTRAN systems, eNB starts MDT measurements such as layer two
Measurement, QoS measurement is carried out to UE business；Measurement amount can be throughput or data volume etc.；Measuring can be according to configuration
Independent up, independent descending or up-downgoing；Measurement can be based on QCI or based on whole UE.
Step 105：Access network element, which is sent, minimizes drive test configuration message to UE, and starts and minimize drive test immediately；
The cell that the configuration configures message by existing measurement is sent to UE；Specifically, can be RRC in the lte networks
Connection reconfigures to be carried in (RRCConnectionReconfiguration) message；
Step 106：UE performs the measurement of configuration requirement, and whether given the correct time in inspection needs to provide positional information；
UE receive configuration after according to configuration measured accordingly, if such as E-UTRAN systems be configured with M1 measure,
UE should carry out corresponding RSRP and RSRQ measurement；
According to prior art, UE report conditions when minimizing drive test immediately are periodicity or event triggering, such as all
During phase property type, terminal configures according to MDT checks the need for actively triggering acquisition positional information in end cycle；Such as thing
When part triggers type, terminal checks whether need according to MDT configurations when for example A2 events (Event A2) meet when event meets
Actively to trigger acquisition positional information；According in disclosed technology, terminal can also postpone triggering measurement receiving to match somebody with somebody,
In this case, terminal should check whether to need active obtaining positional information.
UE according to MDT configuration determine MDT measurement objects, such as UE distinguish measurement throughput or data volume or its
The MDT measurements of his type, distinguish this measurement and be directed to up or downlink business, and distinguishing is measured based on QCI
Or measured based on whole UE；
UE determines the term of validity of positional information, such as can be set according to UE itself settings or fixed threshold, such as actively
5 milliseconds before acquisition positional information are all the terms of validity；Can also be adjusted according to UE speed, for example, high-speed mobile when
Wait, the term of validity is shorter can be adjusted to 2 milliseconds, and the longer term of validity can be 100 milliseconds when low speed moves, that is, obtain
The time for taking 2 milliseconds or 100 milliseconds before positional information is the term of validity.Because terminal in this example receives MDT with postponing master
Dynamic to obtain positional information, then the positional information is given the correct time necessarily effectively upper, can be without the inspection of time conditions.
Whether UE check measurements object meets business need in the positional information term of validity：For example, if MDT measurement objects
During for uplink service, current business only has downlink business, then it is assumed that is unsatisfactory for business need；Or such as MDT measurement objects
During for QCI type services, if the business without the type QCI, then it is assumed that be unsatisfactory for business need；Or such as MDT surveys
Amount object is data volume (data volume), if data volume be zero or less than some threshold value if think to be unsatisfactory for business will
Ask, the threshold value that basis for estimation can be realized or arranged according to UE；When above-mentioned time conditions and professional qualification are satisfied by requiring,
UE actively attempts to obtain positional information, and otherwise UE abandons actively attempting to obtain positional information.
Step 107：Terminal will get positional information and be sent to network side；
UE presses prior art report measurement results, such as in LTE, UE sends measurement report (measurement report)
Message carries positional information and/or measurement result to eNB.
Embodiment two
For this example explanation based on management MDT, immediately MDT, terminal has got positional information (after the triggering of other business
The positional information of preservation) scene under, terminal judges whether the process of reporting position information, as shown in figure 3, including following
Step：
Step 201：Network management system (EMS) triggering minimizes drive test, and will minimize drive test by southbound interface configures message
It is sent to access network elements, such as eNB or RNC；MDT QoS measurement requests are contained in the message；
Step 202：Access network element selects suitable UE, and starts the MDT QoS measurements of the UE；
This example is the MDT based on management, one or more suitable UE of access network eNB or RNC selection；
According to the requirement of configuration, access network starts UE MDT QoS measurements in this example.Such as in E-UTRAN systems,
ENB starts MDT measurements such as layer two and measured, and QoS measurement is carried out to UE business；Measurement object can be throughput or data
Amount etc.；Measurement can be directed to independent uplink service, independent descending business or up-downgoing business according to configuration；This external pelivimetry is also
Can be based on QCI or based on whole UE.
Step 203：Access network element, which is sent, minimizes drive test configuration message to UE；
The cell that the configuration configures message by existing measurement is sent to UE；Specifically, in the lte networks, Ke Yishi
Carried in RRCConnectionReconfiguration message；
Step 204：UE performs the measurement of configuration requirement, and positional information is checked the need in upper give the correct time；
Receive according to prior art UE and measured accordingly according to configuration after configuring；
UE checks the need for the point of addition information in measurement report in the upper needs that give the correct time, and terminal has relied on it in this example
He obtains positional information at business, that is to say, that the application triggers in terminal in addition to MDT functions obtain position letter
Breath, the positional information after acquisition, which is stayed in terminal, can be used to recorded in measurement report.
UE according to MDT configuration determine MDT measurement objects, such as UE distinguish measurement throughput or data volume or its
The MDT measurements of his type, UE distinguish this measurement and are directed to up or downlink business, and distinguishing is measured also based on QCI
It is to be measured based on whole UE；
UE determines the term of validity of positional information, is obtained due to positional information by other applications triggering, therefore obtain
Time and MDT time of measuring are not consistent, and MDT is configured to preiodic type and event mode two types immediately, in preiodic type MDT
In, such as the cycle is 240 milliseconds, obtains middle part of the time in the cycle of positional information, such as is obtained at the 200th millisecond, position
The valid interval of confidence breath is, for example, 50 milliseconds, then 50 milliseconds and afterwards 50 are obtained before positional information at the 200th millisecond
Millisecond is all to have the term of validity, that is, if first Period Start Time is 0 millisecond and starts to calculate, from the 150th millisecond to 250
Millisecond section is all the term of validity of the positional information, and the term of validity contains the period end time at the 240th millisecond, due to upper
Call time comprising before the deadline, now time conditions meet.UE can also set the term of validity according to the speed of oneself, such as high
When speed is mobile, shorter virtual value is, for example, 2 milliseconds, such as virtual value is longer such as 100 milliseconds when low speed movement,
That is 2 milliseconds or 100 milliseconds of time is the term of validity before positional information is obtained.
Whether UE check measurements object meets portfolio requirement in the positional information term of validity：For example, if MDT measurements pair
During as uplink service, current business only has downlink business, then it is assumed that is unsatisfactory for professional qualification；Such as MDT measurement object pins
During to QCI type services, if there is no the type QCI, then it is assumed that be unsatisfactory for professional qualification；Such as MDT measurement objects are data
Measure (data volume), if data volume be zero or less than some threshold value if think to be unsatisfactory for business need, basis for estimation can
With the threshold value realized or arranged according to UE.When above-mentioned time conditions and professional qualification are satisfied by requiring, UE is by positional information
It is added in measurement report, does not otherwise add, or abandons the positional information.
Step 205：Terminal sends minimum drive test and reported to network side.
UE report measurement results, such as in LTE, UE sends measurement report message to eNB, carries measurement knot
