For easy narration, the indication information that the following embodiment of the invention is carried by common signaling all is that example is set forth with the enumeration type, and indication information is that Boolean type and enumeration type are similar, repeats no more.
In the embodiment of the invention be with the network side eNB (Evolved Node B, evolved NodeB) for example describes, but be not limited to this, every entity with identical function all belongs to protection scope of the present invention.
ENB at first carries out the configuration of MDT configuration information, secondly independent system information block is set in system information, and the MDT configuration information that is used for configuring is placed on this system information block, and sends on broadcast channel by broadcast signaling.ENB also will send indication information to UE by common signaling (call signaling or broadcast signaling) or dedicated signaling, in order to the transmission position of this MDT configuration information of notice UE.When UE read this indication information, UE can obtain the schedule information of this system information block according to this indication information in the SIB1 of system information, and gets access to the MDT configuration information of eNB transmission according to the schedule information of this system information block.
Wherein, eNB sends to UE by broadcast signaling with the MDT configuration information, and following dual mode is arranged: 1, eNB sends the MDT configuration information by broadcast channel for the UE in all service areas; 2, eNB sends out an indication by the fixed system block of information of paging channel/broadcast channel earlier and gives UE, and UE mates, and has only the UE on the coupling just receiving specific MDT configuration information at specific broadcast channel.
Wherein, the MDT configuration information comprises but is not limited to following one or several combined information:
1) MDT general function opening/closing;
2) MDT record (log) configuration information, comprising but be not limited to following one or several combined information:
The startup rule of MDT record promptly starts the MDT record for which UE, satisfied certain rule (as the ability based on UE) can be set start the MDT record, supports positioning function to start the MDT record as being set to, and does not support positioning function not start the MDT record.Owing to be to send by broadcast channel, after all UE received, UE judged whether to satisfy rule (whether supporting as the ability based on the UE) decision that sets and whether starts the UE record, starts the MDT record as the UE that supports positioning function, otherwise does not start.
The beginning that MDT starts with by the time, as be arranged on special time and begin the MDT record, stop the MDT record at special time;
The measurement of MDT record: be meant which MDT measuring amount configuration will write down, comprising but be not limited to following one or several combination:
(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) in follow-up standard process, increase other measuring amount newly, relevant as the QOS of UE, be used for other measuring amount that MBMS optimizes etc.
3) MDT report (log) configuration information, comprising but be not limited to following one or several combined information:

(2) periodically report, comprising Cycle Length and starting time.
(3) report based on absolute time, comprising time started that reports and the dwell time that reports.
(4) reporting based on the UE internal memory: the MDT record data account for the absolute thresholding of UE internal memory, report when accounting on the UE internal memory 1/3 as the MDT record data;
(5) based on the reporting of UE position, comprising: a, based on the rule that reports of UE position, as be set at the city record, arrived the suburb burden of eating dishes without rice or wine and hour reported; Perhaps be that UE is at outdoor record, to reporting during indoor use Home eNodeB; B, MDT report employed resource; Which resource the operating position of c, resource Network Based, configuration use report, as use which RB, which logic channel, which transmission/physical channel report etc.
Below in conjunction with concrete application scenarios, do at technical scheme of the present invention and to carry out further detailed elaboration.
The embodiment of the invention provides a kind of Notification Method of MDT configuration information, adds 1bit MDT configuration and read indication in call signaling, is applicable to the UE of connected state or Idle state, specifically may further comprise the steps:
When judging that reading the MDT configuration in call signaling reads indication bit, forward step 303 to;
When judging that not reading the MDT configuration in call signaling reads indication bit, forward step 301 to.
The embodiment of the invention is example (also can be used for UMTS system etc.) with the LTE system, need in call signaling, add 1bit MDT configuration and read indication bit, if exist this MDT configuration to read indication bit indication in the call signaling, then UE obtains MDT configuration information place system information block; If do not exist this MDT configuration to read indication bit indication in the call signaling, then UE does not obtain MDT configuration information place system information block.Wherein, the MDT configuration of adding in the call signaling (Paging Message) is read the following band of instruction content and is glided shown in the literal of ruling:

}
In the embodiment of the invention, the Notification Method of MDT configuration information can also for: in SIB1, carry this MDT configuration by system information and read indication bit.The content of system information block to be correctly obtained, the schedule information among the SIB1 must be at first read.When eNB can be sent to UE transmission MDT configuration information under needs, can notify UE by following dual mode:
1, by call signaling notice UE system information modification.
At this moment, if UE is known system information modification by call signaling, then UE reads SIB1 from system information, and obtains the schedule information of MDT configuration information place system information block from SIB1, thereby knows and need read the MDT configuration information.
2, carrying the MDT configuration in SIB1 reads indication bit and requires UE to read.
At this moment, if UE has directly read SIB1, and indication UE obtains MDT configuration among the SIB1, and then UE obtains the schedule information of MDT configuration information place system information block from SIB1, thereby knows and need read the MDT configuration information.
The Notification Method of MDT configuration information in the embodiment of the invention can also read indicating bit for carry the MDT configuration in PDCCH, and UE reads the MDT configuration information by the PDCCH notice.Particularly, at first newly-increased MDT_RNTI (Radio Network Temporary Identifier RNTI, Radio Network Temporary Identifier), and MDT configuration is set in the PDCCH of MDT_RNTI reads indicating bit, its method to set up reads with the MDT configuration indicates being provided with of bit similar.Secondly, when UE reads this MDT configuration when reading indicating bit in PDCCH, UE then obtains the MDT configuration information from system information block, repeat no more herein.Need to prove, adopt this method, do not need to merge with beep-page message, and UE runs through PDSCH (the Physical Downlink Shared Channel that PDCCH goes up does not need to continue to read the back behind the MDT_RNTI of carrying, Physical Downlink Shared Channel), just adopt the PDCCH of MDT_RNTI carrying not dispatch PDSCH.
More than carried out detailed elaboration at Notification Method for the MDT configuration information, but when adopting this mode, reporting of MDT measurement result needs a trigger condition, can adopt in the following dual mode any:
1), triggers reporting of MDT measurement result: be divided into and periodically report or Event triggered reports by UE.
2), triggering reporting of MDT measurement result: eNB by eNB can require UE that the MDT measurement result of accumulation is reported to particular UE transmission indication.
Advice method can be carried among call signaling or the PDCCH for MDT being reported indication.Wherein, the MDT in the call signaling reports and is designated as MDT and reports indication bit, and MDT reports and is designated as MDT and reports indicating bit among the PDCCH.
Below in conjunction with concrete application scenarios, carry out further detailed elaboration at the method that eNB triggering MDT measurement result reports.
Whether the method that the embodiment of the invention provides a kind of MDT of triggering measurement result to report is added 1bit MDT and is reported indication in call signaling, be used for notice and require UE to report the MDT measurement result, is applicable to the UE of connected state or Idle state, specifically may further comprise the steps:
Step 401, when eNB notice UE reports the MDT measurement result, in call signaling, add 1bit MDT and report indication bit.
Step 402, UE monitor call signaling, judge that whether reading MDT in call signaling reports indication bit.
When judging that reading MDT in call signaling reports indication bit, forward step 403 to;
When judging that not reading MDT in call signaling reports indication bit, forward step 401 to;
The MDT measurement result that step 403, UE tissue get access to forms MDT and measures message.
Step 404, UE report MDT to measure message, and this MDT measures in the message and carries the MDT measurement result.
Preferably, eNB can also carry the MDT measurement at call signaling and open or close indication bit.After UE reads this MDT measurement unlatching or closes indication bit, stop all MDT and measure, optionally delete all MDT measurement results, and/or deletion MDT configuration information.Concrete grammar reports indication bit similar with carry MDT at call signaling, repeats no more herein.Certainly, UE also can after UE obtains the MDT configuration information, need not the relevant indication of opening described in the above-mentioned embodiment of the invention, can measure.
ENB triggers the method that the MDT measurement result reports in the embodiment of the invention, can also report the MDT measurement result for using PDCCH notice UE.Particularly, at first newly-increased MDTRE_RNTI, and in the PDCCH of MDTRE_RNTI, MDT is set and reports indicating bit, be used to notify UE whether to require to report.Secondly, when UE reads MDT when reporting indicating bit in PDCCH, UE organizes the MDT measurement result and sends MDT to eNB and measures message.Need to prove, adopt this method, UE does not need to continue to read the PDSCH of back after having read the MDTRE_RNTI that carries on the PDCCH, just adopts the PDCCH of MDTRE_RNTI carrying not dispatch PDSCH.
Preferably, eNB can also increase MDTDE_RNTI newly, and MDT measurement unlatching is set in the PDCCH of MDTDE_RNTI or closes indicating bit.When UE reads MDT measurement unlatching or closes indicating bit from the MDTDE_RNTI of PDCCH carrying after, stop all MDT and measure, optionally delete all MDT measurement results, and/or deletion MDT configuration information.Concrete grammar reports indication bit similar with carry MDT at PDCCH, repeats no more herein.Need to prove, after this moment, UE ran through the MDTDE_RNTI of the last carrying of PDCCH, still do not need to continue to read the PDSCH of back, just adopt the PDCCH of MDTDE_RNTI carrying not dispatch PDSCH.Certainly, UE also can after UE obtains the MDT configuration information, need not the relevant indication of opening described in the above-mentioned embodiment of the invention, can measure.
Preferably, when using PDCCH that UE is indicated, not only can indicate UE as an indicating bit is set in the above-mentioned embodiment of the invention, can also indicate respectively a plurality of measuring amount (measuring amount that may newly add after comprising) by a plurality of indicating bits are set, thereby realize opening and/or close different MDT and measure.
