101E-PDN in Fig. 1 (Extern Packet Data Network) is outside public data network, and various types of bag data are provided.Bag data are transferred to 103 gateway general packet radio service (being GPRS hereinafter to be referred as GPRS) support nodes (being GGSN hereinafter to be referred as Gateway GPRS Support Node) by external network by predetermined interface 102.GGSN receives after data, and data are sent to 105 Serving GPRS Support Nodes (hereinafter to be referred as SGSN) by interface 104.Between GGSN and SGSN, connect by tunnel, interface 104 meets the agreement of gn interface, has the standard of this interface in TS25.413.SGSN receives after data, data need to be sent to 107 service wireless network controllers (hereinafter to be referred as SRNC).In WCDMA, between SGSN and RNC, be to connect by tunnel, if also do not set up the tunnel of transfer of data, SGSN sends message by predetermined interface 106 and sets up the Deta bearer between SRNC, if set up tunnel, SGSN sends to SRNC data by 106 interfaces.Interface 106 meets the agreement of Iu interface, and the standard of Iu interface comprises the agreement RNSAP agreement of control plane, and the agreement of datum plane.RNSAP agreement comprises the signaling process of setting up datum plane, and datum plane has stipulated the form in the data of Iu interface transmission.107 SRNC receives after data, data need to be sent to 109NodeB.If the bearer context for data transmission between SRNC and NodeB is not also set up, SRNC sends message by predetermined interface 108 and sets up the Deta bearer between base station, and transmission message is set up the wireless link between base station and UE to UE.Establish after Deta bearer, SRNC is responsible for data to be packaged into predetermined form, and sending to base station 109,108 interfaces by 108 interfaces is Iub interface, and the standard of Iub interface comprises the agreement NBAP agreement of control plane, and the agreement of datum plane.NBAP agreement has comprised the signaling process of setting up Iub interface Deta bearer, and the agreement of datum plane has stipulated the form of the data of Iub interface transmission.109 base stations send to 110UE data by the wireless link of air interface.Between two RNC, also can have interface, if interface exists, this interface is followed the agreement of RNSAP.When the community below UE moves to another one RNC, SRNC is originally that a new Deta bearer link is set up in the community below new RNC, and this RNC is known as Drift Radio Network Controller (being called for short DRNC).Data send to DRNC by SRNC, then send to base station by DRNC.SRNC originally also can initiate reset process, the function of SRNC is transferred to DRNC upper, and after reset process, DRNC just becomes the SRNC of UE.
MDT (Minimization ofdrive tests) is to transmit some metrical informations at control plane, to reduce manual testing's burden.MDT measures will support real-time and non real-time measurement.The configuration information of measuring is configured in Access Network control system (E-UTRAN or UTRAN) by network management system, then sends to UE by Access Network control system RRC message.The MDT measurement result of UE sends to E-UTRAN/UTRAN, and measurement report can comprise positional information and temporal information.E-UTRAN/UTRAN sends to the MDT entity in core net measurement result.
According to MDT initiate mode, MDT can be divided into based on management MDT and the MDT based on signaling.MDT based on management refers to that E-UTRAN/UTRAN receives from management entity the message that MDT activates, and the MDT based on signaling refers to that E-UTRAN/UTRAN receives from MME/SGSN the message that MDT activates.
Fig. 2 has described the structure chart of MDT.The 201st, management node (Element Management is called for short EM), under UMTS system, it can be SGSN or an independent node.201 management nodes send follows the tracks of activation request message to 202 network nodes, and 202 network nodes can be the RNC in UMTS system, comprise the configuration information of MDT in message.The configuration information of MDT mainly comprises: MDT regional extent, reporting mechanism configuration, track reference (Trace Reference, be called for short TR), Trace collects the entity IP address of (Trace Collection Entity is called for short TCE), job category, the information such as MDT data anonymity.Above-mentioned job category can be configured to one of Four types: Immediate MDT only, Logged MDT only, Trace only, ImmediateMDT and Trace.MDT regional extent has configured needs to carry out MDT measurement in which region.
202 network nodes send to UE measuring configuration, and UE carries out MDT measurement according to configuration, and in meeting report condition, measurement result is sent to 202 network nodes, and 202 network nodes will send measurement report to TCE.
202 network nodes have been preserved MDT record, and according to predefined strategy, send MDT and record to TCE.
Specifically, in the time carrying out MDT measurement, SGSN sends CN INVOKE TRACE message to RNC, and this message comprises MDT configuration information.The type that MDT configuration information comprises MDT, the type can be arranged to type immediately, recordable type, immediately and following-up type; Also comprise MDT regional extent, the scope that this information has indicated MDT to measure, can be arranged to cell list, band of position indication (being called for short LAI) list, Routing Area indication (being called for short RAI) list, and whole PLMN scope.LAI and RAI are the position indication of operator's definition, larger than the scope of community, can comprise Yi Zu community.Wherein LAI is larger than the scope of RAI.MDT configuration information also comprises the measuring object of MDT, and for example measuring object can be to measure the energy and the quality that receive signal, and the mechanism of measuring object report, for example, be periodically to report.
If MDT type is type immediately, RNC sends and measures configuration messages to UE, allows UE measure and reports.UE measures according to the configuration of measuring object, according to the configuration of reporting mechanism, measurement result is reported to message by measurement and sends to RNC.When the community below UE moves to DRNC, if the community below DRNC still in measuring range, UE can proceed to measure and report, and measures and reports if the community below DRNC not in measuring range, need to stop the MDT of UE.For the MDT measurement of type immediately, UE does not know the measuring range of MDT at present, and it is upper that this measuring range is kept at RNC, and therefore RNC determines whether discharging MDT and measures and initiate new RRC measurement configuration messages, allows UE not carry out measurement and the report of MDT.
Current problem is, when UE moves under DRNC, the Serving cell of UE is the community below DRNC, and that should judge that also discharging the MDT that is configured in UE measures by which RNC.The invention provides the method addressing this problem.A method is to be judged by DRNC, and SRNC sends to DRNC MDT configuration information, and DRNC judges that the community at current UE place is whether in measuring range.Or DRNC does not receive MDT configuration information, but the MDT that UE has been configured measures, and DRNC also will discharge the measurement configuration of the MDT that is configured in UE, and according to current definition, DRNC can not directly discharge the configuration of UE to UE transmission RRC message.
Whether another method is to allow community that SRNC judges current UE place in measuring range, and according to current definition, SRNC does not have enough information to judge.Specifically, if MDT regional extent is arranged to cell identification list or is arranged to whole region, SRNC has obtained the cell ID of Serving cell and the PLMN of service mark below DRNC, can judge that community below DRNC is whether in scope, but, if MDT regional extent is arranged to LAI list or RAI list, current SRNC does not know LAI and the RAI of the community below DRNC, and SRNC has no idea to judge
