Same MDT tasks, and the measurement data for causing user terminal to report can not determine it is which MDT task, cause to report failure,
The problem of to measure unsuccessfully.
Fig. 1 is a kind of flow chart of MDT measurement methods one embodiment provided by the embodiments of the present application.
This method may include following steps：
101：When the MDT is the MDT based on region, operation management maintainance (Operator Administrator＆
Maintenance, OAM) module when getting MDT tasks, sends to Call- Control1 (Calling Control, CC) module and creates
Build the task requests of the MDT tasks.
The present embodiment mainly describes the MDT based on region.
MDT includes mainly the MDT based on the region and MDT based on signaling.It is to select certain in the MDT based on region
Whole user terminals in one configuration cell are configured, and configuration process includes issuing configuration parameter, and trigger user terminal and press
It is measured according to configuration parameter.
Wherein, OAM modules and CC modules are provided in the function module namely the embodiment of the present application in base station
Operation is executed by base station.
In the MDT based on region, the MDT tasks are by operation management maintainance center (Operation and
Maintenance Center, OMC) it is issued to base station, the OAM modules in base station receive the MDT tasks.
The MDT tasks carry configuration parameter, and the configuration parameter includes task identification, metrical information, configuring area letter
The contents such as breath.
After OAM modules receive MDT tasks, i.e., the task requests for creating the MDT tasks are sent to CC modules, to increase
Add MDT tasks.
102：The CC modules judge whether the task identification that not there is no the MDT tasks and whether the MDT tasks
Configuration parameter meet audit condition, if being to be, then follow the steps 103, otherwise terminate flow.
Wherein, the task identification is for MDT tasks described in unique mark.
When CC modules receive the task requests for creating MDT tasks, judge in base station whether the existing MDT tasks are appointed
Business mark, if the task identification of the existing MDT tasks, you can directly to terminate flow.To avoid existing in a base station
When two identical MDT tasks, which corresponding MDT task can not be determined for the measurement data that user terminal reports, cause to survey
The problem of amount failure.
The configuration parameter of the MDT tasks whether meet audit condition may include the task identification whether effectively and
Whether the task type of the MDT tasks area type for configuring cell, areal, measures the other configurations parameters such as content
Meet 3GPP agreements regulation.
The task identification can be by Mobile Country Code MCC (MCC：Mobile Country Code)+mobile network code
(MNC, Mobile Network Code)+tracking mark (Trace ID) is constituted, and MCC and MNC constitute public land mobile network
Network identifies (Public Land Mobile Network ID, PLMNID.By in task identification first three byte, that is, MCC+MNC with
The PLMNID of base station configuration is compared, and shows that task identification is invalid if inconsistent, the audit fails.
It cause what user terminal was unable to measure to ask by the audit to configuring parameter, when can be wrong to avoid configuration parameter
Topic.
It, can be to be somebody's turn to do it is first determined whether existing in order to save resource and time since the content that configuration parameter includes is more
MDT task identifications；In the task identification of the existing MDT tasks, you can directly to terminate flow, without subsequently being judged.
103：When the judging result is to be, the CC modules selection is in the configuring area of the MDT tasks
User terminal configured.
The task identification that there is no the MDT tasks in base station shows not creating the MDT tasks, Yi Jipei in base station
When setting parameter and meeting audit condition, you can to select user terminal to be configured.
In the present embodiment, the MDT based on region can select whole user terminals in a certain configuration cell to be configured, because
This is configured by user terminal of the CC modules selection in the configuration cell of the MDT tasks.To avoid user's end
End is not in configuration cell, the problem of can not measuring.
Wherein, since a base station can establish multiple cells, MDT tasks may be just for one or several in base station
User terminal configuration in a cell.
Therefore in the selection course of user terminal, can not there be the task identification of the MDT tasks in base station, with
And after configuration parameter meets audit condition, it can be determined that whether user terminal affiliated subdistrict is in the configuring area of MDT configuration requirements
In domain, if so, configured again to the user terminal in the configuring area, to avoid when user terminal in the same base station but
Not when the region of MDT configuration requirements, it may appear that the problem of being unable to measure.
It includes that will configure parameter to be issued to user terminal, and trigger user terminal according to described to carry out configuration to user terminal
Configuration parameter measures.
Inventor is by a series of the study found that in the prior art, MDT measures the problem of failing and is often as user
Terminal can not measure or the data of user terminal measurement can not be reported and be caused.Therefore in the present embodiment, for being based on
The MDT in region is measured, after base station gets MDT tasks, it is first determined whether there are the task identification of the MDT tasks and
Whether the configuration parameter of the MDT tasks meets audit condition, and in the case where judging result is to be, selection is located at described
User terminal in the configuring area of MDT tasks is configured.By to configure parameter audit and user terminal selection,
It the problem of can not being measured to avoid user terminal, can be to avoid existing in base station by the judgement to MDT task identifications
Two identical MDT tasks, and the measurement data for causing user terminal to report can not determine it is which MDT task, cause
It reports lost property to the authorities and loses.
Wherein, since the task type of MDT tasks generally includes to report (Immediate MDT) type and daily record immediately
(Logged MDT) type is reported, reporting types refer to user terminal measurement in connected state and report pattern immediately, one
Denier meets report condition, is reported immediately.And what daily record reporting types were issued in connection foundation, and measure and tie
Fruit record carries out in an idle state, and it is also to establish to carry out in connection to report.
For different task type in the embodiment of the present application, the opportunity configured to user terminal and item can be carried out
Part judged, as shown in Fig. 2, in another embodiment provided by the present application, the method may include：
101：When the MDT is the MDT based on region, when OAM modules get MDT tasks, sends and create to CC modules
Build the task requests of the MDT tasks.
102：The CC modules judge whether the task identification that not there is no the MDT tasks and whether the MDT tasks
Configuration parameter meet audit condition, if being to be, then follow the steps 201, otherwise terminate flow.
Step 101 and step 102 may refer to embodiment illustrated in fig. 1, no longer be repeated herein.
In the present embodiment, step 103 may include：
201：The MDT tasks task type be immediately on give the correct time, selection positioned at the MDT configuring area in,
And the user terminal not configured according to reporting types immediately is reported configuration immediately.
Wherein, be located in configuring area, the user terminal that is not configured according to reporting types immediately may include not into
The user terminal of any configuration of row and the user terminal that daily record reports configuration is carried out.Namely in task type it is immediately to report
When, even if user has been carried out daily record and reports configuration or do not carry out any configuration, configuration is reported immediately；And for into
Row reports the user terminal of configuration then without configuration immediately.
It is reported the user terminal of configuration no longer to be reported configuration immediately immediately, can allow be reported immediately and match
The user terminal continuation set is reported according to configuration before, and the UE of configuration is not reported to be reported configuration immediately immediately,
So that UE carries out the configuration of different configuration parameters in a configuring area, it is conducive to collect more comprehensive data.
To reconfigure all UE in configuring area, it may be used and delete original MDT tasks, re-issue MDT
The mode of task is realized.
202：It is to give the correct time in daily record in the task type of the MDT tasks, selection is located in the configuration cell of the MDT,
And the user terminal progress daily record that daily record reports is supported to report configuration.
Wherein, it is located in configuring area, supports that the user terminal that daily record reports includes the user's end for not carrying out any configuration
Daily record is held and has carried out to report configuration or reported the user terminal of configuration immediately.Namely work as task type
For daily record reporting types when, no matter user terminal whether carried out daily record reports configuration either report immediately configuration or do not carry out
Any configuration re-starts daily record and reports configuration.
Due to being to measure in an idle state for daily record reporting types, for the user for supporting daily record to report
Terminal can be configured, user terminal by whether supporting daily record reporting types to judge user terminal, to avoid
User terminal carries out the problem of daily record reports configuration to lead to not measure when not supporting daily record reporting types, to user terminal.
In order to be properly received measurement data that user terminal reports and distinguish, as another embodiment, such as
Described in Fig. 3, after CC modules configure user terminal, the method can also include：
104：The CC modules are that configured user terminal assignment record identifies, and sends and carry to the OAM modules
The instruction message of the record identification, the record identification is for distinguishing different user terminals.
105：The OAM modules create the corresponding record identification memory node, the storage according to the instruction message
Node is for preserving the measurement data that the corresponding user terminal of the record identification reports.
CC modules are directed to the user terminal configured in the MDT tasks, and a uniqueness note can be distributed for it
Record mark, and sent to OAM modules and carry the record identification instruction message.
After OAM modules receive the instruction message, the corresponding record identification memory node is created.
When CC modules receive the measurement data of user terminal reporting base station, it is sent to OAM modules immediately and carries record
The measurement data for the user terminal for belonging to same record mark can be incorporated on same file by mark, the OAM modules
It reports to OMC.
Wherein, memory node can refer to buffer zone etc..
In the present embodiment, by distributing the record identification of uniqueness for configured user terminal, can effectively it distinguish
The measurement data that different user terminals report.
Wherein, the record identification for user terminal distribution can be stored in the predetermined word in the contextual information of user terminal
Duan Zhong, the preset field can refer to track record reference mode (trace Rcord Session Reference).
Wherein the distribution of the record identification can there are many realization methods, in one possible implementation：
Preset field in the contextual information of each user terminal is attached, and there are one initial values.
After user terminal has carried out MDT configurations, it can be judged, if the value of preset field is initial value, table
Show not to the user terminal assignment record ident value, then then carries out the assigning process of record sign value, detailed process to it
It is illustrated below：
When first user terminal carries out MDT with postponing, the value of distribution is maximum value, such as 65534, then by itself and base
Preset field in standing in the contextual information of all user terminals is compared, without identical value, just maximum value
65534 assignment, first user terminal；It postpones, maximum value is successively decreased, such as distribute when second user terminal progress MDT matches
65533, then it is compared with the preset field in the contextual information of all user terminals in base station, if uniquely, it will
The value 65533 is assigned to the preset field in the user terminal contextual information, as record sign value, and so on, for
Third has carried out the user terminal of MDT configurations, then distributes 65530 and carry out uniqueness judgement.
Namely the CC modules are that configured user terminal assignment record identifies and carries out uniqueness judgement, for convenience
Distribution, one group of data that the value of record identification can select one group of incremental data or successively decrease are respectively allocated to user terminal.
Refer to being configured to some or multiple specific user terminals for the MDT based on signaling.In order to enable base
MDT in the signaling and MDT based on cell uses identical interface, to reduce code development quantity etc., therefore as shown in figure 4,
To the MDT based on signaling, present invention also provides another embodiments of MDT measurement methods, and the method may include following
Several steps：
401：When the MDT is the MDT based on signaling, the MDT that the CC modules receive the user terminal that MME is sent appoints
Business.
The MDT tasks of OMC are first issued in MME, and base station is sent to by MME, and the CC modules in base station receive the MDT and appoint
Business.
402：The configuration parameter of the MDT tasks is mapped as the MDT based on region and configures parameter by the CC modules, and is sentenced
Whether the configuration parameter of breaking meets audit condition.
In order to enable the MDT based on the signaling and MDT based on region uses identical interface, it is necessary first to appoint MDT
The configuration parameter of business is mapped, and is converted to the configuration parameter of the MDT based on region, in order to be able to according to based on region
MDT configuration flows handle the MDT configurations based on signaling.
Wherein, since the value in the interface of the MDT tasks based on management is to need to map at present as defined in operator oneself
Content can include but is not limited to task type, MDT measure content, report immediately the MDT measurements of configuration report trigger condition and
Daily record reports the measurement of configuration to report interval time etc..
In the present embodiment, configuration parameter is audited by CC modules, it is careful whether the configuration parameters of the MDT tasks meets
Core condition may include that whether the task identification effective and the task type of the MDT tasks, the region class for configuring cell
Type, areal measure whether the other configurations parameters such as content meet 3GPP agreements regulation.
403：When the configuration parameter meets audit condition, the CC modules send establishment task to the OAM modules
Task requests.
404：The OAM modules judge whether the task identification of the MDT tasks, and judge to tie to CC module feedbacks
Fruit.
405：The CC modules determine the task identification there is no the MDT tasks according to the judging result, to described
User terminal is configured.
Wherein, OAM modules are being determined there are when the task identification of the MDT tasks, then are disappeared to CC module feedbacks are uncertain
Breath when OAM modules determine the task identification there is no the MDT tasks, then creates MDT tasks, and determine to CC module feedbacks
Message configures user terminal if CC modules receive determining message.
In the present embodiment, the MDT based on signaling is measured, after base station gets the MDT tasks of MME transmissions, is judged
Whether the configuration parameter of task identification and the MDT tasks with the presence or absence of the MDT tasks meets audit condition, is judging
Result is in the case of being, selection is configured positioned at the user terminal of the configuration cell of the MDT tasks.By to configuration
The audit of parameter can be to avoid by the judgement to MDT task identifications the problem of can not being measured to avoid user terminal
There are two identical MDT tasks in base station, and the measurement data for causing user terminal to report can not determine it is which MDT appoints
Business, the problem of causing to report unsuccessfully.Pass through the technical solution of the embodiment of the present application so that MDT and the application based on signaling are real
It applies the MDT based on region in example and identical configuration flow may be used so that identical interface, before improving measurement success rate
It puts, reduces code development quantity.
Wherein, since the task type of MDT tasks generally includes reporting types immediately and daily record reporting types,
The CC modules also need to judge the configuration whether user terminal can carry out corresponding task type.
And the representation of the task type and the task type of the MDT based on region due to the MDT based on signaling differs
Sample, in order to ensure that the MDT based on the signaling and MDT based on region can use identical interface, as another embodiment：
Task type in the configuration parameter can be mapped as the task class of the MDT based on region by the CC modules
Type.
It is to start (TRACESTART) message, TRACE using tracking for example, when MME issues MDT tasks to base station
START is the message in agreement, in the protocol when assignment of mission type：Reporting types are indicated with 0 immediately, immediately reporting types and
Trace indicates that daily record reporting types are indicated with 2 with 1.And in the MDT based on region, report immediately indicated with 0, daily record reports use
1 expression Trace is indicated with 2, is reported indicated with 3 with Trace immediately.It therefore, can will be in the configuration parameter by mapping
Task type is mapped as the task type of the MDT based on region.
Such as when the MME task types for being sent to base station are that daily record reporting types are indicated with 2, by 2 after base station receives
The task type being mapped as in the MDT based on region, i.e., be indicated with 1, therefore can be used with the MDT based on region same
The interface of sample.
Therefore, after using identical interface, the process flow of the MDT based on region may be used in the MDT based on signaling,
Therefore the CC modules, which to the user terminal configure, may include：
Task type in the configuration parameter is to report immediately, and the user terminal does not carry out giving the correct time on immediately,
