Description
Technical field
The present invention relates to wireless communication technology, particularly a kind of minimization drive test measurement method and subscriber equipment.
Background technology
One, MDT (minimization drive test, minimum road test) measures classification brief introduction.
Immediate MDT (instant MDT): the MDT carrying out at connected state measures and reports.Multiplexing RRM (Radio Resource Management, RRM) measurement mechanism, once meet report condition, immediately to eNB/RNC (evolution base station/radio network controller; RNC:Radio Network Controller, radio network controller) report.
Logged MDT (non-instant MDT): the MDT carrying out at Idle state measures, and reports at follow-up connected state.Once meet the trigger condition of configuration, will obtain measurement result and store (log), on follow-up suitable opportunity, report eNB/RNC.
Conventionally, for ease of statement, alleged log refers to that execution " obtains measurement result and store " resulting stored record after This move in the industry; Logging refers to that execution " obtains measurement result and store " This move.
Two, geographic range (area scope) configuration brief introduction.
MDT measurement is to have restriction in geographic range, is currently divided into 3 kinds of situations:
1) network does not have the geographic range that explicit configuration MDT measures, and UE carries out MDT log measurement by all communities in whole RPLMN (Registered Public Land Mobile Network, the public land mobile network of registration);
2) UE (User Equipment, subscriber equipment) also can, by the explicit configuration of network 30Ge community at the most, use CGI (Cell Global Identifier, Cell Global Identity) to identify, under this configuration, UE only carries out MDT log measurement in configuration Liao community;
3) UE also can be by the explicit configuration of network TA/LA/RA (Tracking Area/Location Area/Routing Area, tracking area/this area/Route Area) list, under this configuration, when UE is only resident in these TA/LA/RA Nei communities, just carry out MDT log measurement.
Three, the existing measurement introduction of MDT.
Following 7 UE measuring amount have been determined in existing MDT measurement:
1, Periodical downlink pilot measurements (cycle descending pilot frequency is measured);
2, Serving Cell becomes worse than threshold (it is poorer than setting thresholding that service district becomes);
3, Transmit power headroom becomes less than threshold (it is poorer than setting thresholding that PHR becomes);
4, Random access failure (random access failure);
5, Paging Channel Failure (paging channel takes defeat);
6, Broadcast Channel failure (broadcast channel takes defeat);
7, Radio link failure report (Radio Link Failure report).
Except above-mentioned 7 measuring amount, in follow-up standard process, do not get rid of the measuring amount that increases other, as the relevant measuring amount of the QoS of UE (QoS Quality of Service, service quality).If several in these measuring amount are during for the immediate MDT of connected state, when network has issued after the configuration of these measurements, UE will monitor at connected state, and after having event to be triggered, still multiplexing RRM measures the reporting message using and proceeds to reporting of network side.
The deficiencies in the prior art are: existing scheme, agreement have only stipulated to carry out the UE behavior of MDT measurement in area scope, in UE measuring process, if crossed over the border of measuring geographic range configuration, how this processes the problems such as MDT measurement configuration, timer also not have technical scheme to solve UE.

Embodiment
In following mobile communication system, wish, by introducing the mechanism of network self-organization, to reduce the artificial participation of the network planning and Operation and Maintenance, by network based statistic Automatic Optimal parameter, reduce construction and the operation cost of network.In order to reduce the O&M cost of network, hope can be taked network configuration UE report method, reduces the work of artificial drive test.On the other hand, also wish to obtain the wireless measurement information in the region that common drive test cannot arrive.
In LTE (Long Term Evolution, Long Term Evolution), at R10 (version 10), set up the project and determined that MDT adopts the framework of chain of command (control plane) at present, the benefit of this framework is exactly that base station can be controlled UE accurately.The configuration and UE the reporting to network that adopt chain of command framework need to use RRC (Radio Resource Control, Radio Resource is controlled) signaling bear network to carry out UE.The geographic range area scope of network to a measurement of UE configuration, UE carries out normal MDT measurement within the scope of this.
But inventor notices: MDT Log only measures at UE and just carries out during in idle condition, network has configured MDT measured zone to UE, UE is according to autonomous path movement, between different districts, carry out gravity treatment, likely move to outside the measured zone (community/tracking area) of network configuration.But existing scheme, agreement have only stipulated to carry out the UE behavior of MDT measurement in area scope; And in UE measuring process, if crossed over the border of measuring geographic range configuration, how this processes the problems such as MDT measurement configuration, timer also not have technical scheme to solve UE.
Given this, the processing scheme that provides a kind of UE to cross over MDT configuring area in the embodiment of the present invention, in order to provide the solution of UE behavior after the geographic range that UE spanning network configuration MDT measures.Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Fig. 1 is MDT method of measurement implementing procedure schematic diagram, as shown in the figure, crosses over MDT configuring area carry out when MDT measures comprising the steps: at UE
After the geographic range that step 102, UE measure at the MDT that leaves configuration, stop obtaining MDT measurement result.
In concrete enforcement, network issues MDT in connection status to UE and measures configuration, and this configuration comprises the absolute time issuing, the time span timer (timer) that allows this MDT Log to measure, and possible Restriction of the Measuring region.Different according to the processing mode to timer, can be divided into three kinds of modes, respectively: one, timer is continued to timing; Two, delete timer; Three, pause timer timing, describes their embodiments below.
One, timer timer does not suspend, and UE is not logging, until come back to after the geographic range that the MDT of configuration measures.
That is, at UE, leaving after the geographic range that the MDT of configuration measures, can further include:
UE is kept for the timer continuation timing that MDT Log measures, and timer length is that the MDT that network issues to UE measures the timer length in configuration parameter.
In enforcement, can further include:
Before timer expiry, after the geographic range that UE measures at the MDT that gets back to configuration, the MDT issuing to UE by described network measures configuration and starts to obtain MDT Log measurement result and store.
Under which, behind the Restriction of the Measuring zone boundary that UE deviated from network limits, the timer timer of restriction MDT Log whole time of measurement works on and does not suspend, and UE also continues to retain MDT measurement configuration information, but UE does not carry out MDT log measurement, until timer expiry;
Before timer timer is overtime, if crossing over Measured Boundary again, gets back among measured zone UE, UE can, on the basis of measuring before, continue to use the MDT retaining to measure configuration and carry out log DATA REASONING and collection;
The benefit of which is: the triggering relative time stamp of each event of record can not produce error, and periodically the relative time stamp of logging record can not produce error yet.
Two, delete timer, UE deletes configuration.
That is,, after the geographic range that UE measures at the MDT that leaves configuration, can further include:
UE deletes the timer of measuring for MDT Log, and timer length is that the MDT that network issues to UE measures the timer length in configuration parameter.
In enforcement, at UE, deleting after the timer of measuring for MDT Log, can further include:
UE is retained in the MDT issuing to UE by network in the geographic range that the MDT of configuration measures and measures the MDT Log measurement result that configuration is obtained;
UE reports the MDT Log measurement result of reservation after entering connection status.
Further, in enforcement, at UE, leaving after the geographic range that the MDT of configuration measures, further comprising:
UE deletes the MDT Log measurement configuration that network issues to UE.
The benefit of which is: implement simple.Once the appointed area of UE deviated from network configuration, deletes all configurations that MDT log measures, and comprises timer and measured zone restriction, this MDT measures and finishes.But the log result data that UE has measured still retains, after entering connection status, wait reports again.
Three, suspend timer, retain configuration, UE is not logging, gets back to after the geographic range that the MDT of configuration measures, and recovers timer, continues logging.
That is, at UE, leaving after the geographic range that the MDT of configuration measures, can further include:
UE suspends the timer timing of measuring for MDT Log, and timer length is that the MDT that network issues to UE measures the timer length in configuration parameter.
In enforcement, can further include:
After the geographic range that UE measures at the MDT that gets back to configuration, recover timer timing, and the MDT issuing to UE by described network measurement configuration starts to obtain MDT Log measurement result and stores.
On the basis of aforesaid way, in enforcement, when UE suspends the timer timing of measuring for MDT Log, can further include:
UE is left to the time of the geographic range that the MDT of configuration measures and carry out timing.
In enforcement, can adopt timer to carry out timing.
In implementing, can further include:
When the duration leaving surpasses setting threshold, UE deletes the timer of measuring for MDT Log, and/or the MDT that deletion network issues to UE measures configuration.
In enforcement, can further include:
UE reports MDT Log measurement result, upper giving the correct time, determines the relative time stamp of event/periodic recording according to the timer suspending and the duration leaving.
Under which, in order to guarantee the Measuring Time of actual MDT Log in limited range, when UE leaves the measuring range of restriction, the time span timer timer that this MDT Log can be measured suspends, and measures configuration and hangs up, and measures and suspends.Also, UE suspends the timer timing of measuring for MDT Log.
UE left in a period of time of measuring behind localized area, and the probability that comes back to measurement localized area is larger.If UE gets back to and measures in localized area in a period of time, continue to open timer, use the measurement configuration of hanging up to carry out log collection.Also, UE, after the geographic range of MDT measurement of getting back to configuration, recovers timer timing, and the MDT measurement configuration that before suspending by measurement, network issues to UE starts to obtain MDT measurement result and stores.
After if UE is gone for a season, think that the possibility that UE gets back to Restriction of the Measuring region reduces greatly, can delete timer and MDT and measure configuration.Wherein " a period of time " can be to reopen the timer timer ' that an agreement provides, or realized and being settled a dispute by the parties concerned themselves by UE.Also, when the duration leaving surpasses setting threshold, UE deletes the timer of measuring for MDT Log, and/or the MDT that deletion network issues to UE measures configuration.
Fig. 2 is that the MDT log measurement collection MDT of periodic triggers processes implementing procedure schematic diagram, as shown in the figure, can comprise:
Suppose that UE moves to outside the Restriction of the Measuring region of network configuration, proceeds to step 202;
In this step, the object of new timer timer ' is that the time of UE being left to the geographic range that the MDT of configuration measures carries out timing;
Before step 204, Timer ' are overtime, judge that whether UE gets back to former Restriction of the Measuring region, is to proceed to step 205, otherwise proceeds to step 206;
For the MDT log measurement collection of periodic triggers, if the time-out of timer timer can have influence on the calculating of timestamp time stamp, can when timer suspends, reopen another timer timer ", for the calculating of time out; Or multiplexing above-mentioned timer timer '.Timer timer suspends during from the measured zone of UE deviated from network configuration, and timer ' opens during from the measured zone of UE deviated from network configuration.Above-mentioned timer ' or timer " all can carry out timing at timer pause stage, guarantee the accuracy that timestamp calculates:
Relative time stamp=timer+timer '/timer of event/periodic recording ".
