Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of minimum road test MDT method of measurement, equipment and system.
Background technology
In the GSM in future, hope to reduce the manual work of the network planning and Operation and Maintenance and participate in through introducing the mechanism of network self-organization, by network based statistic Automatic Optimal parameter, reduce the construction and the operation cost of network.In order to reduce the O&M cost of network, hope can take network configuration UE (User Equipment, the subscriber equipment) method that reports to reduce the work of artificial drive test, i.e. MDT (Minimization Drive Test, minimum road test) scheme.In addition, also hope to measure the wireless measurement information that common drive test can't arrive the zone that obtains through MDT.
In order to reach the purpose of optimization, the MDT measurement needs the multiple information relevant with UE of statistics, obtains statistics.During MDT measures; The base station according to the upper layer network side (like OAM (Operation Administration and Maintenance; Operations,Administration And Maintenance)) the base station side MDT measurement configuration information that issues; The information type that definite needs are added up (the MDT measuring amount that promptly need obtain), UE side MDT measurement configuration information is made according to the concrete condition of UE in the base station then, and is handed down to concrete UE.Wherein, said UE side MDT measurement configuration information has defined in MDT measures, and whether UE need participate in measuring and reporting the MDT measuring amount, has specifically defined the MDT measuring amount type that UE need measure and report simultaneously.Therefore; According to said base station side MDT measurement configuration information and UE side MDT measurement configuration information; Just clearly in all information types that need add up, which MDT measuring amount is initiatively obtained by the base station in the base station, and which reports the base station after being measured by the UE side again.
In MDT measures; The base station is carried out related with the MDT measuring amount that reception UE reports the MDT measuring amount of initiatively obtaining; Generate the MDT measurement result; And give upper layer network side (like OAM or TCE (Trace Collection Entity follows the tracks of and collects entity)) with this MDT reporting measuring result, be used to carry out the network optimization.
MDT measures and can be divided into following two types among LTE (Long Term Evolution, the Long Term Evolution) Rel-10 (version 10):
Immediate MDT (instant MDT): the MDT that connected state carries out measures and reports.
Logged MDT (non-instant MDT): the MDT that Idle state carries out measures, and reports at follow-up connected state.
It all is the enhancing to coverage optimization that these two types of MDT measure.
At present LTE Rel-11 (version 11) to MDT measurements optimize, on the one hand, optimized the obtain manner of UE geographical location information in the MDT measurement; Make the base station can initiatively obtain the UE geographical location information; Also can ask UE to open the located in connection function, report geographical location information, in other words; The geographical location information of UE both can be that the base station initiatively obtains, and also can be that UE reports; On the other hand, in the MDT measuring amount, introduced the relevant measuring amount (hereinafter to be referred as the QoS measuring amount) of QoS (Quality of Service, service quality), like UE up-downgoing throughput, UE up-downgoing data amount transmitted, UE uplink business data time delay etc.
In LTE Rel-11, some QoS measuring amount (like UE up-downgoing throughput, UE up-downgoing data amount transmitted etc.) can only be in connected state at UE to be measured, yet in real network; If UE has switched the sub-district; Because UE produces service disconnection in handoff procedure, this type QoS measuring amount that will cause the base station to obtain is inaccurate, that is to say that MDT measuring amount that the base station obtains can't react the truth of UE veritably; Just can not obtain MDT measurement result accurately; In follow-up processing procedure, network carries out the network optimization based on inaccurate MDT measurement result, will reach corresponding optimization effect; Even also possibly run counter to desire, cause serious consequence.
Summary of the invention

Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the embodiment of minimum road test MDT method of measurement of the present invention, equipment and system is described in further detail.
The present invention provides a kind of minimum road test MDT method of measurement, is used for the MDT measurement that base station side is carried out, and is as shown in Figure 1, comprising:
Step 101, source base station are confirmed user equipment (UE) when target BS switches, and the MDT that stops said UE measures;
After step 102, target BS were confirmed said UE successful switch, the MDT that begins said UE measured.
In the inventive method; When UE switched, the MDT that source base station stops UE measuring, and at the UE successful switch to target BS; The MDT that begins UE again measures; Owing in the process that switches, stop to carry out the MDT measurement of UE, avoided when UE is in service disconnection, obtaining inaccurate MDT measuring amount, and then avoided producing thus the problem of bad network optimization effect.
Preferably; In the above-mentioned steps 101, said source base station is confirmed UE when target BS switches, and the MDT that stops said UE measures; Specifically comprise: said source base station confirms that UE is when target BS switches; Stop initiatively to obtain the MDT measuring amount of said UE, and/or, stop to receive the MDT measuring amount that said UE reports.
It is pointed out that among the present invention program that the MDT measuring amount that source base station stops initiatively to obtain said UE is meant: source base station stops to measure and getting access to the MDT measuring amount relevant with said UE through said UE being carried out corresponding MDT.
Concrete, the MDT of UE measures can be divided into following three kinds of situation: the MDT measuring amount of only initiatively obtaining said UE through the base station is accomplished, is only obtained through UE and reports the MDT measuring amount to accomplish, initiatively obtains the MDT measuring amount of said UE and UE obtains and report the MDT measuring amount to accomplish jointly through the base station.According to above three kinds of situation, for fear of when UE switches, the base station initiatively obtains insecure MDT measuring amount because of continuing that UE is carried out the MDT measurement, or receives the unreliable MDT measuring amount that UE sends, and the practical implementation process is in this step:
When the MDT of said UE measurement was only initiatively obtained the MDT measuring amount completion of said UE through the base station, said source base station stopped initiatively to obtain the MDT measuring amount of said UE immediately;
When the MDT of said UE measurement was only obtained through UE and reported the MDT measuring amount to accomplish, said source base station stopped to receive the MDT measuring amount that said UE reports immediately;
When measuring through the base station, the MDT of said UE initiatively obtains the MDT measuring amount of said UE and UE obtains and when reporting the MDT measuring amount to accomplish jointly; Said source base station stops initiatively to obtain the MDT measuring amount of said UE immediately, and stops to receive the MDT measuring amount that said UE reports immediately.
Preferably; In the above-mentioned steps 102, after said target BS was confirmed said UE successful switch, the MDT that begins said UE measured; Specifically comprise: after said target BS is confirmed said UE successful switch; The MDT measuring amount of said UE is initiatively obtained in beginning, and/or, begin to receive the MDT measuring amount that said UE reports.
It is pointed out that among the present invention program that the MDT measuring amount that target BS begins initiatively to obtain said UE is meant: target BS begins to measure and get access to the MDT measuring amount relevant with said UE through said UE being carried out corresponding MDT.
Concrete, similar with step 101, the practical implementation process of this step is:
When the MDT of said UE measurement was only initiatively obtained the MDT measuring amount completion of said UE through the base station, said source base station began initiatively to obtain the MDT measuring amount of said UE immediately;
When the MDT of said UE measurement was only obtained through UE and reported the MDT measuring amount to accomplish, said source base station began to receive the MDT measuring amount that said UE reports immediately;
When measuring through the base station, the MDT of said UE initiatively obtains the MDT measuring amount of said UE and UE obtains and when reporting the MDT measuring amount to accomplish jointly; Said target BS begins initiatively to obtain the MDT measuring amount of said UE immediately, and begins to receive the MDT measuring amount that said UE reports immediately.
Preferably, in the inventive method, also comprise: the MDT measurement configuration information that said source base station will be relevant with said UE sends to said target BS; Said target BS receives said MDT measurement configuration relevant information and preserves.
Preferably, relevant with said UE MDT measurement configuration information comprises base station side MDT measurement configuration information and UE side MDT measurement configuration information.Said base station side MDT measurement configuration information is carried out the configuration information that MDT measures for the said base station that is used for that the upper layer network side issues, and said UE side MDT measurement configuration information is that the said UE that is used for that formulate said base station carries out the configuration information that MDT measures and reports the MDT measuring amount;
Concrete, upper layer network side apparatus (like OAM) is handed down to source base station with base station side MDT measurement configuration information when confirming that need carry out MDT measures; Said base station side MDT measurement configuration information has specifically defined the MDT measuring amount that need obtain; Source base station is made UE side MDT measurement configuration information according to the concrete condition of UE then, and is handed down to concrete UE, and said UE side MDT measurement configuration information has defined in MDT measures; Whether UE need participate in measuring and reporting the MDT measuring amount; Simultaneously specifically defined the MDT measuring amount type that UE need measure and report, like this, according to said base station side MDT measurement configuration information and said UE side MDT measurement configuration information; Said source base station can specifically be determined the MDT measuring amount of which type and initiatively obtained by self, and the MDT measuring amount of which type is obtained then by UE and reported; When UE switches, have continuity for making the MDT measurement of before and after the switching said UE being carried out, source base station sends to said target BS with said base station side MDT measurement configuration information and UE side MDT measurement configuration information, and is preserved by said target BS.
It is pointed out that in the inventive method, specifically defined UE in the UE side MDT measurement configuration information and whether need participate in measuring and reporting the MDT measuring amount; Promptly according to said UE side MDT measurement configuration information; Can set UE and carry out the MDT measurement and report the MDT measuring amount, also can set the UE side and not carry out the MDT measurement and report the MDT measuring amount, in other words; When UE side MDT measurement configuration information was preserved in UE this locality, said UE may not just need carry out MDT and measure and report the MDT measuring amount.
There are following two kinds of situation in UE in carrying out the process of switching: delete former UE side MDT measurement configuration information, or, keep former UE side MDT measurement configuration information, no matter which kind of situation occurs, source base station and target BS all can be known according to communication protocol.
Preferably; In the inventive method; When said target BS confirms that said UE deletes from UE side MDT measurement configuration information that source base station receives in handoff procedure, judge that after switching the UE side MDT measurement configuration information of whether preserving according to said target BS carries out MDT and measure; If target BS sends to said UE with the UE side MDT measurement configuration information of self preserving; If not, target BS regenerates UE side MDT measurement configuration information and sends to said UE.The UE side MDT measurement configuration information that regenerates is different from the said UE side MDT measurement configuration information that receives from source base station.
Preferably; Said target BS confirms that said UE keeps the UE side MDT measurement configuration information that receives from source base station in handoff procedure; And confirm after switching to carry out MDT when measuring not according to the UE side MDT measurement configuration information that said target BS is preserved, regenerate UE side MDT measurement configuration information and send to UE.
Wherein, the UE side MDT measurement configuration information that regenerates of target BS is different from the said UE side MDT measurement configuration information that receives from source base station.
As UE when deletion is from UE side MDT measurement configuration information that source base station receives in the process of carry out switching; Measure in order after UE switches to target BS, still to carry out MDT smoothly; Target BS need resend UE side MDT measurement configuration information and give said UE; At this moment, whether the target BS judgement still carries out the MDT measurement according to receive UE side MDT measurement configuration information from source base station, i.e. whether judgement needs said UE still to carry out MDT according to the UE side MDT measurement configuration information that receives from source base station is measured; If; Then target BS will send to said UE from the UE side MDT measurement configuration information that source base station receives, otherwise the UE side MDT measurement configuration information that target BS will be confirmed again sends to said UE.
When UE keeps from UE side MDT measurement configuration information that source base station receives in the process of carry out switching; Whether the target BS judgement carries out MDT according to the said UE side MDT measurement configuration information that receives from source base station after switching measures; If then target BS need not be for further processing, otherwise; Target BS will be confirmed UE side MDT measurement configuration information again and send to said UE, so that said UE upgrades UE side MDT measurement configuration information.
Preferably, before target BS sent switching command, the MDT measurement configuration information that said source base station will be relevant with said UE sent to said target BS; Said target BS specifically with UE side MDT measurement configuration information, is included in the switching command and sends to said UE through said source base station.
Perhaps, before UE accomplished switching, the MDT measurement configuration relevant information that said source base station is relevant with said UE sent to said target BS; Said target BS specifically after UE switches, directly sends to said UE with UE side MDT measurement configuration information.
Concrete, when UE was carrying out deletion in the process of switching from UE side MDT measurement configuration information that source base station receives, target BS sent UE side MDT measurement configuration information to said UE, has following two kinds of situation:
1) target BS sends before the switching command, and the MDT measurement configuration information that said source base station will be relevant with said UE sends to said target BS
Because this moment, UE did not also switch; Said target BS can not be directly and UE communicate, for this reason, target BS can comprise UE side MDT measurement configuration information in the switching command that generates; Then switching command is sent to said source base station, by source base station switching command is transmitted to UE again.
2) before UE accomplished and switches, the MDT measurement configuration relevant information that source base station is relevant with said UE sent to said target BS
After UE switches, target BS can be directly and UE communicate, therefore, target BS directly sends to UE with UE side MDT measurement configuration information.
Preferably, in the inventive method, said source base station stops said UE is carried out after MDT measures, and also comprise: said source base station is with the MDT measuring amount of the said UE that initiatively obtains, and/or the MDT measuring amount that the said UE of reception reports reports.
Concrete; In the inventive method; When UE switches; Source base station stops initiatively to obtain the MDT measuring amount of said UE and/or stops to receive the MDT measuring amount that said UE reports, and its purpose mainly is for fear of in the process that UE switches, carrying out MDT measurements and obtain inaccurate MDT measuring amount because of continuing UE to service disconnection, still in order to guarantee that upper layer network side (like OAM) still can get access to enough comprehensive and accurate MDT measuring amount; Source base station is stopping said UE carried out after MDT measures, and the MDT measuring amount of the said UE that has got access to (comprise initiatively obtain and/or receive that UE reports) is reported the upper layer network side.
Preferably, said MDT measurement includes but not limited to the measurement to QoS measuring amount and/or UE geographical location information.
Concrete, Rel-11 to MDT measurement optimize, on the one hand; Mode to obtaining the UE geographical location information in the MDT measurement is optimized; Make the base station both can initiatively obtain the geographical location information of UE, also can ask UE to open the located in connection function, report its geographical location information; On the other hand, in the MDT measuring amount, introduced the QoS measuring amount, like UE up-downgoing throughput, UE up-downgoing data amount transmitted, UE uplink business data time delay etc.In the above-mentioned QoS measuring amount; Needing is had by what the base station initiatively obtained: UE up-downgoing throughput, UE up-downgoing data amount transmitted; Needing is had by what UE obtained and reported: UE uplink business data time delay; In addition, the UE geographical location information in the MDT measuring amount both can initiatively be obtained by the base station, also can obtain and report the base station by UE.In the practical implementation, the base station can confirm as the case may be that various MDT measuring amount are initiatively to be obtained by the base station, reports the base station again after still being obtained by UE.
Accordingly, the present invention provides another kind of minimum road test MDT method of measurement, is used for the MDT measurement that the UE side is carried out, and is as shown in Figure 2, comprising:
Step 201, user equipment (UE) are confirmed from source base station when target BS switches, to stop to carry out MDT and measure, and stop the MDT measuring amount is reported said source base station;
Step 202 after said UE confirms successfully to switch to said target BS, is restarted to carry out MDT and is measured, and begin the MDT measuring amount is reported said target BS.
Preferably, in the above-mentioned steps 201, the UE UE side MDT measurement configuration information that deletion receives from source base station when switching, this method further comprises: the UE side MDT measurement configuration information that send UE receiving target base station is also preserved.The said UE side MDT measurement configuration information that receives from source base station is that the UE that is used for that source base station is formulated carries out the configuration information that MDT measures and reports the MDT measuring amount.
Concrete; UE will delete from the UE side MDT measurement configuration information that source base station receives; Make UE needn't in the process that difference is switched, safeguard the UE side MDT measurement configuration information that receives from source base station, simplified the processing procedure of UE when switching, improved the switching efficiency of UE.
Preferably; The MDT measurement configuration information that UE receives from target BS; The UE side MDT measurement configuration information of obtaining from source base station for target BS; Perhaps be the UE side MDT measurement configuration information that target BS is confirmed again, the UE side MDT measurement configuration information that target BS is confirmed again is different from the UE side MDT measurement configuration information of obtaining from source base station.
After then said UE confirms successfully to switch to said target BS,, restart and carry out the MDT measurement, and begin the MDT measuring amount is reported said target BS according to current local said UE side MDT measurement configuration information of preserving.Wherein, current local UE side MDT measurement configuration information of preserving receives from target BS.
If what receive is the UE side MDT measurement configuration information that target BS obtains from source base station; Then UE is after switching to target BS; The MDT that still is correlated with according to former UE side MDT measurement configuration information measures; If what receive is the UE side MDT measurement configuration information that target BS is confirmed again, then UE will measure according to the MDT that the UE side MDT measurement configuration information of confirming again is correlated with after switching to target BS.
Preferably, in the said method, UE specifically before switching from the switching command that said source base station sends, obtain the UE side MDT measurement configuration information that said target BS sends.
Concrete; If target BS is before UE switches; Just will send to UE from UE side MDT measurement configuration information or the definite again UE side MDT measurement configuration information that source base station receives; Then since this moment UE can't with the target BS direct communication, in the switching command that said UE forwards through the reception sources base station, get access to the UE side MDT measurement configuration information that said target BS sends.
Perhaps, UE after switching, the UE side MDT measurement configuration information that send the receiving target base station.
Concrete, if target BS after said UE switches, just sends to UE with said UE side MDT measurement configuration information, then since this moment UE can with the target BS direct communication, therefore, UE receives said UE side MDT measurement configuration information from said target BS.
Preferably, in the above-mentioned steps 201, said UE keeps the UE side MDT measurement configuration information that receives from source base station when switching, and this method further comprises:
If said UE receives the UE side MDT measurement configuration information that target BS sends, then will be updated to the UE side MDT measurement configuration information that receives from target BS from the UE side MDT measurement configuration information that source base station receives.
Concrete; UE still protects the UE side MDT measurement configuration information that receives from source base station in handoff procedure; Then when target BS confirms that UE can still carry out relevant MDT measurement according to former UE side MDT measurement configuration information after switching, just can send UE side MDT measurement configuration information to UE again, like this; Target BS just can save unnecessary operation, has simplified the treatment mechanism of target BS.
After then said UE confirms successfully to switch to said target BS, restart according to current local UE side MDT measurement configuration information of preserving and to carry out MDT and measure, and begin the MDT measuring amount is reported said target BS.
Concrete; Because UE has kept the UE side MDT measurement configuration information that receives from source base station when switching; When the MDT that then after target BS is being confirmed the UE switching, can still be correlated with according to former UE side MDT measurement configuration information measures; Just no longer sent UE side MDT measurement configuration information to said UE, then UE is after switching, and the MDT that the UE side MDT measurement configuration information from the source base station reception of still preserving according to this locality is correlated with measures; When the MDT that after target BS is being confirmed the UE switching, can not be correlated with according to former UE side MDT measurement configuration information again measures; Will generate the UE side MDT measurement configuration information that is different from former UE side MDT measurement configuration information; And send to said UE; Then UE receives after the said UE side MDT measurement configuration information, and the UE side MDT measurement configuration information from the source base station reception with preserve this locality is updated to the UE side MDT measurement configuration information that receives from target BS; And after switching completion, the MDT that is correlated with according to the UE side MDT measurement configuration information after upgrading measures.
Preferably, in the said method, before switching, said UE obtains said UE side MDT measurement configuration information from the switching command that said source base station sends.
Concrete; If target BS is before UE switches; When the UE side MDT measurement configuration information that just will confirm again sends to UE; Then since this moment UE can't with the target BS direct communication, in the switching command that said UE forwards through the source base station that receives, get access to target BS and confirm UE side MDT measurement configuration information again.
Perhaps, UE after switching, the UE side MDT measurement configuration information of confirming again that send the receiving target base station.
Concrete; If target BS is after said UE switches, the UE side MDT measurement configuration information that just will confirm again sends to UE, then since at this moment UE can with the target BS direct communication; Therefore, UE receives the said UE side MDT measurement configuration information of confirming again from said target BS.
Preferably, said MDT measurement includes but not limited to the measurement to QoS measuring amount and/or UE geographical location information, as comprises the measurement to UE uplink business data time delay.
