Embodiment

(1) MDT measures

The measuring amount that MDT measures the UE that confirms includes but not limited to:

1, Periodical downlink pilot measurements (the 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 (access failure at random)

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)

It should be noted that except above-mentioned 7 measuring amount in follow-up standard process, do not get rid of the measuring amount that increases other, for example, the relevant measuring amount of the QOS of UE (Quality of Service, service quality) repeats no more in the embodiment of the invention.

Concrete, above-mentioned measuring amount can be used for the logged MDT of Idle state, issued the configuration of some measurement when network after, UE will measure and the log information of keeping records according to configuration parameter, after getting into connected state, proceed to reporting of network.

(2) measurement configuration of IDLE attitude logged MDT

The measurement configuration of Logged MDT is used independent handling process, and is independent fully with the measurement configuration of RRM/immediate MDT.Wherein, the measurement configuration of Logged MDT includes but not limited to:

1, the configuration of the measurement that will write down comprises measuring object (frequency) etc.

2, the measuring amount of LoggedMDT is fixed; To EUTRA(EvolvedUniversalTerrestrialRadioAccessNetwork; The general continental rise wireless access network of evolution) be RSRP(ReferenceSignalReceivedPower; The reference symbol received power) and RSRQ(ReferenceSignalReceivedQuality; The reference symbol quality of reception); To UTRA(UniversalTerrestrialRadioAccessNetwork; General continental rise wireless access network) be RSCP(ReceivedSignalCodePower; Received signal code power) with the Ec/No(noise ratio); To GERAN(GSMEDGERadioAccessNetwork; GSM EDGE Radio Access Network) is Rxlev(ReceivedSignalLevel, Received signal level).

3, the periodically measurement triggering of descending pilot frequency intensity is supported in the triggering of Logging incident configuration, comprises it and measures (for the multiple of IDLE pattern DRX) at interval; Also can support Event triggered, for example, record measured value when the Serving cell quality is lower than a thresholding.

4, the absolute time that comes into force of measurement configuration is stabbed, and is used for UE and when measurement and report, feeds back to network.

5, the configuration of Logging total time length is used to control logging time of UE.Wherein, this timer timer begins to start when configuration, when the overtime logging of timer stops, deleting measurement configuration simultaneously, but log result will keep at least 48 hours.If UE is in connected state always, then this MDT does not measure and starts.

6, the configuration of measured zone (optional) can be used the form of TA (Tracking Area, tracking area)/RA (Routing Area, route district)/LA list, also can use the form of cell list (cell list), is used to control the zone of UE logging.If do not dispose measured zone, then the UE acquiescence is all measured in the whole PLMN (Public Land Mobile-communication Network, public land mobile communication network) of registration.

(3) Log reports indication

Under the situation of Logged MDT; When UE has available log; If get into connected state or move to new sub-district, then UE need can use log indication (Log available) to report network through RRC (RadioResource Control, Radio Resource control) signaling.

With the LTE system is example, and the RRC connection is set up process as shown in Figure 2, and UE sends RRCConnectionRequest message to network side, and network side sends RRCConnectionSetup message to UE; After successfully setting up the RRC connection; UE can send RRCConnectionSetupComplete message to network side; At this moment; Carry the indication information whether UE preserves available log in this RRCConnectionSetupComplete message; After network side is received this indication, can the MDT measurement log result who preserve be reported subsequent request UE.

Same, in the switching and process of reconstruction of LTE, UE can notify new sub-district whether at UE available log result to be arranged with sending this log available indication for the sub-district of the Target cell that switches/be reconstructed into.

In addition, in UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system) system, if SRNS relocation process has taken place, UE also can send to Target cell with log available indication.

(4) Log reports content

The measurement report of Logged MDT can self-explanatory, even i.e.: the network that the receives log result deploy content measured of this MDT not also can directly explain the content that reports through the log measurement result.Wherein, above-mentioned functions can realize that network and UE no longer identify specific logged MDT measurement configuration information through measuring ID through the measurement ID mechanism of no longer multiplexing connected state.

In addition, can also comprise geographical location information in the Logged MDT reporting information, UE provides this information according to the principle of doing one's best.

Further, UE also needs the absolute time that feedback configuration issues to stab, and the relative time that stabs of this absolute time relatively during each log measuring amount, and these information all will report network at last.

Based on the correlation technique of MDT, under normal circumstances, the UE that is in the IDLE state can find the sub-district resident, and detects effective measurement result; When UE was in the covering cavity, UE does not have any sub-district can be resident, and this moment, the MDT behavior of UE did not have complete rational solution, thereby can not guarantee that UE can leave the position that covers the cavity under log.
