Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present application, be clearly and completely described the technical scheme in the embodiment of the present application, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the application's protection.
It is medium that the technical scheme of the embodiment of the present application is mainly applicable to LTE system.
User terminal (UT, User Terminal) also can be referred to as subscriber equipment (UE, UserEquipment), mobile terminal (MT, Mobile Terminal), travelling carriage (MS, Mobile Station) etc., can communicate with one or more core net through wireless access network (such as, RAN, Radio Access Network).
Base station can refer to the evolved base station (being called eNB or e-NodeB, evolutionNodeB) in LTE.In addition, one or more community (cell) may be supported/manage in a base station, and when user terminal needs and network service, network insertion is initiated in selection community by it.
In the embodiment of the present application, at minimum road test (MDT, Minimazation of Drive Tests) when being MDT based on region, after base station gets MDT task, first judge whether whether the configuration parameter of the task identification and described MDT task that there is described MDT task meets examination & verification condition, when judged result be, select the user terminal being positioned at the allocating cell of described MDT task to be configured.By to the examination & verification of configuration parameter and the selection of user terminal, user terminal can be avoided cannot to carry out the problem measured, by can avoid the MDT task that in base station, existence two is identical to the judgement of MDT task identification, and which MDT task causes the measurement data of user terminal to send up to determine be, cause reporting failure, thus measure failed problem.
The flow chart of a kind of MDT method of measurement embodiment that Fig. 1 provides for the embodiment of the present application.
The method can comprise following step:
101: when described MDT is the MDT based on region, operation management maintain (OperatorAdministrator & Maintenance, OAM) when module gets MDT task, the task requests creating described MDT task is sent to Call-Control1 (Calling Control, CC) module.
The present embodiment mainly describes the MDT based on region.
MDT mainly comprises the MDT based on region and the MDT based on signaling.Based in the MDT in region, be select the whole user terminals in a certain allocating cell to be configured, layoutprocedure comprises and issues configuration parameter, and activated user terminal is measured according to configuration parameter.
Wherein, OAM module and CC module are all the functional modules be arranged in base station, are also that the operation in the embodiment of the present application is all performed by base station.
Based in the MDT in region, described MDT task is issued to base station by operation management maintain center (Operationand Maintenance Center, OMC), and the OAM module in base station receives this MDT task.
This MDT task carries configuration parameter, and described configuration parameter comprises the contents such as task identification, metrical information, configuring area information.
After OAM module receives MDT task, namely send the task requests creating described MDT task to CC module, to increase MDT task.
102: the configuration parameter of task identification and whether described MDT task that described CC module judges whether not exist described MDT task meets examination & verification condition, is then perform step 103 if be, otherwise process ends.
Wherein, described task identification is used for MDT task described in unique identification.
When CC module receives the task requests creating MDT task, judge the task identification that whether there is this MDT task in base station, if there is the task identification of this MDT task, namely can direct process ends.During to avoid there is two identical MDT tasks in a base station, the measurement data for user terminal to send up cannot determine which MDT task corresponding, causes measuring failed problem.
Whether the configuration parameter of described MDT task meets that examination & verification condition can comprise the whether effective and task type of described MDT task of described task identification, whether other configuration parameters such as area type, areal, measurement content of allocating cell meet 3GPP agreement regulation.
Described task identification can by Mobile Country Code MCC (MCC:Mobile Country Code)+mobile network code (MNC, Mobile Network Code)+follow the tracks of mark (Trace ID) to form, MCC and MNC constitutes public land mobile network mark (Public Land Mobile Network ID, PLMNID.Compared by the PLMNID that first three byte in task identification and MCC+MNC and base station configure, if inconsistent, show that task identification is invalid, examination & verification is not passed through.
By the examination & verification to configuration parameter, the problem causing user terminal to measure when configuration parameter can be avoided wrong.
The content comprised due to configuration parameter is more, in order to saving resource and time, first can judge whether to there is this MDT task identification; There is the task identification of this MDT task, namely can direct process ends, without the need to carrying out follow-up judgement.
103: described judged result be time, the user terminal that described CC model choice is positioned at the configuring area of described MDT task is configured.
In base station, there is not the task identification of described MDT task, show in base station, not create this MDT task, and when configuration parameter meets examination & verification condition, user terminal namely can be selected to be configured.
In the present embodiment, the MDT based on region can select whole user terminal in a certain allocating cell to be configured, and the user terminal being therefore positioned at the allocating cell of described MDT task by described CC model choice is configured.To avoid user terminal not in allocating cell, the problem measured cannot be carried out.
Wherein, because multiple community can be set up in a base station, MDT task may just for the user terminal configuration in one or several community in base station.
Therefore in the selection course of user terminal, the task identification of described MDT task can be there is not in base station, and after configuration parameter meets examination & verification condition, user terminal affiliated subdistrict can be judged whether in the configuring area of MDT configuration requirement, if, again the user terminal in this configuring area is configured, to avoid when user terminal not when the region of MDT configuration requirement, there will be the problem that cannot measure in same base station.
Be configured to comprise to user terminal and configuration parameter is issued to user terminal, and activated user terminal is measured according to described configuration parameter.
Inventor finds through a series of research, and in prior art, MDT measures failed problem normally because user terminal cannot carry out measuring or the data of user terminal measurement cannot report and cause.Therefore in the present embodiment, MDT based on region is measured, after base station gets MDT task, first judge whether whether the configuration parameter of the task identification and described MDT task that there is described MDT task meets examination & verification condition, when judged result be, select the user terminal being positioned at the configuring area of described MDT task to be configured.By to the examination & verification of configuration parameter and the selection of user terminal, user terminal can be avoided cannot to carry out the problem measured, by can avoid the MDT task that in base station, existence two is identical to the judgement of MDT task identification, and cause the measurement data of user terminal to send up to determine being which MDT task, causing reporting failure.
Wherein, task type due to MDT task generally includes and reports (Immediate MDT) type and daily record to report (Logged MDT) type immediately, reporting types refers to user terminal measurement in connected state and reports pattern immediately, once meet report condition, report immediately.And daily record reporting types issues in connection establishment situation, and measurement and outcome record are carried out in an idle state, reporting also is carry out in connection establishment situation.
For different task type in the embodiment of the present application, can carry out opportunity of being configured user terminal and condition judges, as shown in Figure 2, in another embodiment that the application provides, described method can comprise:
101: when described MDT is the MDT based on region, when OAM module gets MDT task, the task requests creating described MDT task is sent to CC module.
102: the configuration parameter of task identification and whether described MDT task that described CC module judges whether not exist described MDT task meets examination & verification condition, is then perform step 201 if be, otherwise process ends.
Step 101 and step 102 can embodiments shown in Figure 1, no longer repeat at this.
In the present embodiment, step 103 can comprise:
201: give the correct time on immediately at the task type of described MDT task, select the configuring area being positioned at described MDT, and do not report configuration immediately according to the user terminal that reporting types is configured immediately.
Wherein, be positioned at configuring area, can not comprise according to the user terminal that reporting types is configured immediately the user terminal that do not carry out any configuration and carry out the user terminal that daily record reports configuration.Also namely give the correct time on immediately at task type, report configuration even if user has carried out daily record or do not carry out any configuration, reporting configuration all immediately; Then be not configured for reporting the user terminal of configuration immediately.
The user terminal of configuration is reported to report configuration no longer immediately immediately, can allow and report the user terminal of configuration to continue to report according to configuration before immediately, and report the UE of configuration to report configuration immediately immediately, make UE in a configuring area carry out the configuration of different configuration parameter, be beneficial to collection more comprehensively data.
To be reconfigured by all UE in configuring area, can adopt and delete original MDT task, the mode re-issuing MDT task realizes.
202: be that daily record is given the correct time at the task type of described MDT task, select the allocating cell being positioned at described MDT, and support that user terminal that daily record reports carries out daily record and reports configuration.
Wherein, be positioned at configuring area, the user terminal supporting the user terminal that reports of daily record to comprise not carry out any configuration and carried out the user terminal that daily record reports configuration or report configuration immediately.Also, namely when task type is daily record reporting types, no matter whether user terminal has carried out daily record reports configuration or reports configuration immediately or do not carry out any configuration, all re-starts daily record and reports configuration.
Owing to being measure in an idle state for daily record reporting types, therefore for supporting that the user terminal that daily record reports all can be configured, to user terminal, whether user terminal is by supporting that daily record reporting types judges, avoiding user terminal when not supporting daily record reporting types, daily record being carried out to user terminal and reports configuration to cause the problem that cannot measure.
In order to can correctly receive the measurement data of user terminal to send up and distinguish, as another embodiment, as described in Figure 3, after CC module is configured user terminal, described method can also comprise:
104: described CC module is the user terminal assignment record mark configured, and sends the Indication message carrying described record identification to described OAM module, and described record identification is for distinguishing different user terminals.
105: described OAM module creates corresponding described record identification memory node according to described Indication message, and described memory node is for preserving the measurement data of user terminal to send up corresponding to described record identification.
CC module, for the user terminal be configured in described MDT task, can distribute a uniqueness record identification for it, and carries this record identification Indication message to the transmission of OAM module.
After OAM module receives this Indication message, create corresponding described record identification memory node.
When CC module receives the measurement data of user terminal to send up base station, be sent to OAM module immediately and carry record identification, the measurement data of the user terminal belonging to same record identification can be incorporated into same file and report to OMC by described OAM module.
Wherein, memory node can refer to a buffer zone etc.
In the present embodiment, being distributed the record identification of uniqueness by the user terminal for having configured, effectively can distinguish the measurement data that different user terminals reports.
Wherein, the record identification of distributing for user terminal can be kept in the preset field in the contextual information of user terminal, and this preset field can refer to track record reference node (trace Rcord SessionReference).
Wherein the distribution of this record identification can have multiple implementation, in a kind of possible implementation:
Preset field in the contextual information of each user terminal is with an initial value.
After user terminal carries out MDT configuration, can judge it, if the value of preset field is initial value, represent not to this user terminal assignment record ident value, then then carry out to it assigning process recording sign value, detailed process illustrates as follows:
After first user terminal carries out MDT configuration, the value of distributing is maximum, such as 65534, then the preset field in the contextual information of user terminals all in itself and base station is compared, there is no identical value, just this first user terminal of maximum 65534 assignment; After second user terminal carries out MDT configuration, maximum is successively decreased, such as distribute 65533, then comparing with the preset field in the contextual information of all user terminals in base station, if uniquely, then the preset field in this user terminal contextual information is given by this value 65533 assignment, as record sign value, the like, the 3rd is carried out to the user terminal of MDT configuration, then distributed 65530 and carry out uniqueness judgement.
Also namely described CC module is that the user terminal assignment record configured identifies and carries out uniqueness judgement, and conveniently distribute, the value of record identification can select the one group of data increased progressively or one group of data of successively decreasing to distribute to user terminal respectively.
MDT based on signaling is referred to some or multiple specific user terminal is configured.Identical interface is adopted in order to make the MDT based on signaling and the MDT based on community, to reduce code development quantity etc., therefore as shown in Figure 4, to the MDT based on signaling, present invention also provides another embodiment of MDT method of measurement, described method can comprise following step:
401: when described MDT is the MDT based on signaling, described CC module receives the MDT task of the user terminal that MME sends.
The MDT task of OMC is first issued in MME, is sent to base station by MME, and the CC module in base station receives this MDT task.
402: the configuration parameter of described MDT task is mapped as the MDT configuration parameter based on region by described CC module, and judge whether described configuration parameter meets examination & verification condition.
Identical interface is adopted in order to make the MDT based on signaling and the MDT based on region, first the configuration parameter of MDT task is needed to map, be converted to the configuration parameter of the MDT based on region, so that can process for the MDT configuration based on signaling according to the MDT configuration flow based on region.
Wherein, due to based on management MDT task interface in Zhi Shi operator oneself regulation, need at present mapping content can include but not limited to task type, MDT measure content, report the MDT measurement of configuration to report trigger condition and daily record to report the measurement of configuration to report interval time etc. immediately.
In the present embodiment, audited configuration parameter by CC module, whether the configuration parameter of described MDT task meets that examination & verification condition can comprise the whether effective and task type of described MDT task of described task identification, whether other configuration parameters such as area type, areal, measurement content of allocating cell meet 3GPP agreement regulation.
403: when described configuration parameter meets examination & verification condition, described CC module sends the task requests of creation task to described OAM module.
404: described OAM module judges whether the task identification that there is described MDT task, and to CC module feedback judged result.
405: described CC module determines according to described judged result the task identification that there is not described MDT task, is configured described user terminal.
Wherein, OAM module is when determining the task identification that there is described MDT task, then to the uncertain message of CC module feedback, when OAM module determines the task identification that there is not described MDT task, then create MDT task, and to CC module feedback determination message, if CC module receives determine message, then user terminal is configured.
In the present embodiment, MDT based on signaling is measured, after base station gets the MDT task of MME transmission, judge whether whether the configuration parameter of the task identification and described MDT task that there is described MDT task meets examination & verification condition, when judged result be, select the user terminal being positioned at the allocating cell of described MDT task to be configured.By the examination & verification to configuration parameter, user terminal can be avoided cannot to carry out the problem measured, by can avoid the MDT task that in base station, existence two is identical to the judgement of MDT task identification, and cause the measurement data of user terminal to send up to determine being which MDT task, causing the problem reporting failure.By the technical scheme of the embodiment of the present application, making the MDT based on signaling can adopt identical configuration flow with the embodiment of the present application based on the MDT in region, make identical interface, improving under the prerequisite measuring success rate, decreasing code development quantity.
Wherein, the task type due to MDT task generally includes reporting types and daily record reporting types immediately, and therefore, described CC module also needs to judge whether described user terminal can carry out the configuration of corresponding task type.
And the representation of the task type of the task type due to the MDT based on signaling and the MDT based on region is different, in order to ensure that the MDT based on signaling can use identical interface with the MDT based on region, as another embodiment:
Task type in described configuration parameter can be mapped as the task type of the MDT based on region by described CC module.
Such as, time MME issues MDT task to base station, use to follow the tracks of to start (TRACESTART) message, TRACE START is the message in agreement, in the protocol during assignment of mission type: reporting types represents with 0 immediately, reporting types and Trace represent with 1 immediately, and daily record reporting types represents with 2.And based in the MDT in region, report with 0 representing immediately, daily record reports and represents that Trace represents with 3 with Trace with 2 representing, reporting immediately with 1.Therefore by mapping, the task type in described configuration parameter can be mapped as the task type of the MDT based on region.
Such as when MME sends to the task type of base station to be that daily record reporting types represents with 2, when being mapped as 2 based on the task type in the MDT in region after base station receives, namely representing with 1, therefore just can use same interface with the MDT based on region.
Therefore, after adopting identical interface, the MDT based on signaling can adopt the handling process of the MDT based on region, and therefore described CC module is configured can comprises described user terminal:
Task type in described configuration parameter is for report immediately, and described user terminal does not carry out giving the correct time immediately, or be that daily record reports at the task type of described MDT task, described user terminal is supported daily record is given the correct time, and judges whether described configuration parameter meets examination & verification condition.
Wherein, conveniently distinguishing user terminal, based in the MDT of signaling, be adopt cell ID and terminal iidentification to distinguish different user terminals, but cell ID and terminal iidentification at least needs to take two fields in prior art.In order to avoid interface redundancy, be convenient to safeguard, reduce running time, as described in Figure 5, in another embodiment that the application provides, described method can comprise following step:
501: when described MDT is the MDT based on signaling, described CC module receives the MDT task of the user terminal that MME sends, and the configuration parameter of described MDT task is kept at the contextual information of described user terminal.
502: the configuration parameter of described MDT task is mapped as the MDT configuration parameter based on region by described CC module, and judge whether described configuration parameter meets examination & verification condition.
503: when described configuration parameter meets examination & verification condition, described CC module is that described user terminal distributes association identification, and the cell ID of described association identification and described user terminal and terminal iidentification are set up corresponding relation, and be kept in the contextual information of described user terminal.
504: described CC module sends the task requests of carrying the described MDT task of establishment of described association identification and described configuration parameter to described OAM module.
505: described OAM module judges whether the task identification that there is described MDT task, and carries the judged result of described association identification to CC module feedback.
506: when described CC module determines according to described judged result the task identification that there is not described MDT task, search the user terminal that described association identification is corresponding, according to the configuration parameter stored in described user terminal contextual information, described user terminal is configured.
This association identification can define according to actual needs, can unique identification user terminal.
