Description

A method of transmission MDT configuration

Technical field

The present invention relates to wireless communication technique, in particular to a kind of method for supporting transmission MDT configuration.

Background technique

Fig. 1 is the system architecture diagram of System Architecture Evolution (SAE).Wherein:

User equipment (UE) 101 is the terminal device for receiving data.Evolved universal terrestrial radio access network (E- UTRAN) 102 be Radio Access Network, provides the macro base station (eNodeB/ of access radio network interface including for UE NodeB).Mobile management entity (MME) 103 is responsible for mobile context, session context and the security information of management UE.Service network It closes (SGW) 104 and the function of user plane is mainly provided, MME 103 and SGW 104 are likely to be at same physical entity.Packet count According to functions such as the responsible charging of network gateway (PGW) 105, Lawful Interceptions, same physical entity can also be in SGW 104.Plan Slightly and charging regulation function entity (PCRF) 106 provides service quality (QoS) strategy and charging criterion.General Packet Radio Service Supporting node (SGSN) 108 is that transmission in Universal Mobile Communication System (UMTS) for data provides the network node of routing and sets It is standby.Home subscriber server (HSS) 109 be UE local ownership subsystem, be responsible for protection include user equipment current location, The user informations such as address, user security information, the packet data content of user equipment of service node.

MDT (Minimization of drive tests) is in the control some metrical informations of planar transmission, to reduce people The burden of work test.MDT measurement will support real-time and non real-time measurement.The configuration information of measurement is configured by Network Management System In access network control system (E-UTRAN or UTRAN), UE then is sent to by accessing network control system RRC information.UE's MDT measurement result is sent to E-UTRAN/UTRAN, and measurement report may include location information and temporal information.E-UTRAN/ UTRAN is sent to measurement result the MDT entity in core net.

According to the mode that MDT is initiated, MDT is segmented into the MDT based on the management and MDT based on signaling.Based on management MDT refers to that E-UTRAN/UTRAN receives the message that MDT is activated from management entity, and the MDT based on signaling refers to E-UTRAN/ UTRAN receives the message that MDT is activated from MME.

Fig. 2 describes the structure chart of the MDT based on management.201 be management node (Element Management, abbreviation EM), 201 management nodes send tracking activation request message to 202 network nodes, and 202 network nodes can be in LTE system ENB includes the configuration information (MDT Configuration) of MDT in message.The configuration information of MDT mainly includes: the position MDT Alternative condition, reporting mechanism configuration, track reference (Trace Reference, abbreviation TR), Trace collect entity (Trace Collection Entity, abbreviation TCE) IP address, job category, the information such as MDT data anonymity.Above-mentioned job category can To be configured to one of four seed types: Immediate MDT only, Logged MDT only, Trace only, Immediate MDT and Trace.The UE which position the position MDT alternative condition is configured with may be selected the user of MDT measurement.Position choosing The condition of selecting can be configured to the range of the cell perhaps range of TAC or entire PLMN.UE in range, may be selected It is the UE of MDT.One MDT process of TR unique identification.During a MDT, eNB can choose multiple users and carry out MDT Measurement.

202 network nodes selection UE does MDT measurement, when eNB selects UE, to consider the user that MME is sended over Position alternative condition inside approval information and MDT configuration information, if UE disagrees MDT or UE and is unsatisfactory for position selection Condition, the UE cannot be chosen as being the UE of MDT.UE is chosen, eNB is that UE distribution track record session refers to (Trace Recoding Session Reference, abbreviation TRSR).MDT configuration information is sent to UE by eNB.Configuration information includes: position Set alternative condition, reporting mechanism configuration, track reference (Trace Reference), the mark of the IP address of TCE.

UE carries out MDT measurement according to configuration, and when meeting report condition, measurement result is sent to network section Point eNB, eNB will send Cell Traffic Trace message to MME.ENB obtains TR, TRSR from the measurement report that UE is reported, The mark of the IP address of TCE and measurement result, eNB send Cell Traffic Trace message to MME.Message contains TR, TRSR, cell ID, eNB/MME are the IP address of the S1AP Id and TCE of UE distribution., MME find UE IMSI or IMSI/IMEI (SV) is sent to TCE by IMEI (SV).

202 network nodes save MDT record, and according to strategy predetermined, according to the IP of the UE TCE sent The mark of location finds the IP address of corresponding TCE.The relationship of the IP address of the mark and corresponding TCE of the IP address of TCE is preparatory It is stored in above eNB.ENB sends MDT and records the information sent to TCE, TCE combination MME, is known that MDT record is for which A little UE's.

The MDT type that MDT based on signaling is supported is also four above-mentioned seed types, and different places is MDT initiation message It is that eNB is sent to from MME, configuration information is that MME is sent to eNB, and TR, TRSR are that MME is distributed.In UE in different eNB Between when move, MDT configuration information needs to be transferred to above purpose eNB.And the MDT of the MDT based on management match confidence Breath does not need to be transferred to above purpose eNB.

In order to support the MDT under multiple PLMN to measure, network need for UE configure a MDT PLMN list, the list by MME is sent to eNB, and MDT PLMN is a subset of equivalent PLMN, and MME establishes request message by S1 initial UE context, Switching request message or downlink NAS transmit message and the MDT PLMN list of UE are sent to eNB.

If MME is configured with, some UE carries out MDT measurement or eNB has selected some UE to carry out MDT measurement, and eNB is sent RRC information allows user to carry out the measurement of MDT to the UE of connection mode.From the point of view of the measurement of configuration UE, there are two types of MDT types: note Record type MDT (Logged MDT) and immediate-type MDT (Immedicate MDT).If configuring the measurement that UE carries out recordable type MDT, ENB sends Logged MDT measuring configuration message to UE, includes the configuration information of MDT, such as TR, TRSR, MDT measurement in message Range, the MDT measurement that UE is carried out in idle mode.If configuring the measurement that UE carries out immediate-type MDT, eNB sends common Reconfiguration message is wirelessly connected to UE, it, can be in the report configuration of report comprising measurement and the configuration information reported in message The instruction that position report is carried out comprising one, if UE carries out MDT measurement, and matching according to network immediately comprising the instruction It sets, measurement result is reported to network.

When carrying out S1 or X2 switching, the context of UE has been transferred to purpose eNB from source eNB.The letter of corresponding MDT Breath, MDT configuration as mentioned above, if need to shift, there is different processing in different situations.

For the MDT based on management, when UE has carried out the switching of X2, source eNB sends switching request message, does not need to pass through MDT configuration information element (MDT Configuration IE) is sent to purpose eNB by switching request message.

It for the MDT based on signaling and is immediate-type MDT, source eNB needs in switching request message MDT configuration information Element is sent to purpose eNB.If measured in the UE that source cell has been configured, the RRC or more in switching request message The configuration of the measurement to UE is further comprised in text.Purpose eNB is according to MDT range information in MDT configuration information element, if purpose For cell not within the scope of MDT, purpose eNB, which is sent, is wirelessly connected reconfiguration message to UE, discharges the measuring configuration of UE.

It for the MDT based on signaling and is recordable type MDT, source eNB is not needed in switching request message MDT with confidence Breath element is sent to purpose eNB.

S1 switching is also suitable identical principle, and difference is that MME decides whether to send MDT configuration information to purpose eNB Element.

It for the MDT based on signaling and is immediate-type MDT, source eNB is needed in switching request message according to current method Middle that MDT configuration information element is sent to purpose eNB, before sending switching request, current method is that source eNB needs to judge Whether purpose PLMN belongs to MDT PLMN list, if so, MDT configuration information element is sent to purpose eNB by source eNB, if It is not that source eNB does not need a MDT configuration information element and is sent to purpose eNB.

This method has implemented a problem, currently, in the switching request order of S1 and X2, the configuration information of MDT Element is included in inside tracking information element, for example, TR, TRSR are included in inside tracking information element, MDT measurement Range is included in inside MDT configuration information element.Tracking information element is the mesh that forwarding is required within the scope of entire PLMN ENB, if purpose eNB has received tracking information element, without receiving MDT configuration information element, purpose eNB be will be considered that Need to carry out UE tracking measurement, and in fact, the TR/TRSR it is corresponding be MDT measurement.In this way, purpose eNB is just carried out The operation of mistake.

To make the objectives, technical solutions, and advantages of the present invention more comprehensible, right hereinafter, referring to the drawings and the embodiments, The present invention is described in further detail.

Embodiment one describes MME and the relevant information of MDT is sent to eNB, and the relevant information of MDT is arranged comprising MDT PLMN Table, MDT configuration information etc., when X2 switching, source eNB has selected new service PLMN, source eNB to determine whether to a MDT Configuration information element is sent to purpose eNB.Method shown in Fig. 3 may comprise steps of:

Step 301:MME sends MDT PLMN list to eNB.The information can be transmitted by following method:

Request message is established by UE initial context, the information contains UE in the mark of S1 interface, Yao Jianli at present E-RAB information, the cryptographic capabilities of UE, UE wireless capability, the information such as current service PLMN and ePLMN list.In the message In, the list of MDT PLMN is further comprised, which is the set of PLMN mark, net of the UE in the corresponding PLMN of the mark The measurement of MDT can be carried out under network.

Message is transmitted by downlink NAS, the information contains UE in the mark of S1 interface at present, non-access layer information, when The information such as preceding service PLMN and ePLMN list.Within the message, the list of MDT PLMN is further comprised.

By S1 switching request message, the message contains UE contextual information, RRC contextual information, switching limit at present The information such as list processed.Within the message, the list of MDT PLMN is further comprised.

Step 302:MME sends tracking active information to eNB.Track active information include TR, TRSR, TCE IP address, The interface of tracking, tracking depths also include MDT configuration information element, and MDT configuration information element includes the type of MDT, and MDT is surveyed The information such as the range of amount.The information can be transmitted by following method:

Request message is established by UE initial context, the information contains UE in the mark of S1 interface, Yao Jianli at present E-RAB information, the cryptographic capabilities of UE, UE wireless capability, the information such as current service PLMN and ePLMN list.In the message In, further comprise tracking active information element.

By S1 switching request message, the message contains UE contextual information, RRC contextual information, switching limit at present The information such as list processed.Within the message, tracking active information element is further comprised.

Start request message by tracking and contain the mark of UE within the message, further comprises tracking active information member Element.

Step 303:eNB receives the measurement report of UE, according to the measurement report of UE, needs to be switched to UE on purpose eNB Face.There is X2 interface between source eNB and purpose eNB, source eNB initiates X2 handoff procedure.Source eNB sends switching request message to purpose ENB, source eNB are the service PLMN mark that UE selects purpose eNB to use above, and source eNB includes new in switching request message Service PLMN mark.Switching request message also includes the type of MDT.

If being configured with for UE in 302 steps and carrying out immediate-type MDT measurement, and purpose service PLMN is in MDT PLMN In list, handoff request message active information element containing tracking, tracking active information element the inside includes MDT configuration information member Element and other information element, other information element include TR, TRSR, TCE IP, track interface, tracking depths.

If being configured with for UE in 302 steps and carrying out immediate-type MDT measurement (including immediate-type onlyMDT, immediate-type MDT And tracking), and purpose services PLMN not in MDT PLMN list, according to current definition, if purpose service PLMN is not MDT configuration information element is not included in switching request in MDT PLMN list.But other letters in tracking active information element Breath, such as TR, TRSR, TCE IP track interface, and tracking depths are to be transferred to purpose in switching request message to be included in eNB.In this way, purpose eNB, which will be considered that, to track message of the UE on specified interface, therefore, according to the present invention, switching is asked Seeking message also includes the instruction of MDT type, which indicates UE and be configured for Trace and Immediate MDT, purpose Base station needs to track the message on specified interface, if MDT type indicates UE and is configured for Immediate MDT The related information element with Trace in switching request message is ignored in only, purpose base station.

Or the tracking active information element in switching request message also includes an information instruction, indicates whether to be configured with UE carries out Trace, carries out Trace to UE if the information indicate that being configured with, purpose base station is to disappearing on specified interface Breath is tracked, if the information indicate that not configuring Trace, having in switching request message with Trace is ignored in purpose base station The information element of pass wrong will not track UE.

If being configured with other MDT measurements, it (includes MDT that switching request message, which does not include tracking active information element, Configuration information element and other information element).

According to another aspect of the present invention, eNB receives the measurement report of UE, according to the measurement report of UE, needs UE It is switched to above purpose eNB.There is X2 interface between source eNB and purpose eNB, source eNB initiates X2 handoff procedure.ENB transmission in source is cut Changing request message and giving purpose eNB, source eNB is the service PLMN mark that UE selects purpose eNB to use above, and source eNB is asked in switching It asks in message and is identified comprising new service PLMN.If being configured with UE in source base station carries out MDT measurement, switching request message Also comprising tracking active information element, tracking includes MDT configuration information element and other information in active information element.It needs It is bright, at present only source base station be configured with the measurement of the immediate-type MDT based on signaling (including immediate-type only MDT, immediately Type MDT and tracking), it include MDT configuration information element in the tracking active information element in switching request message.If in source base Station is configured with common tracking (Trace), (to match confidence without MDT comprising tracking active information element in switching request message Cease element).Other MDT are configured, not comprising tracking active information element in switching request message.

Step 304: purpose eNB saves information, sends switching response message and gives source eNB.Message includes that purpose eNB can be built Vertical E-RAB information, the RRC information to UE that purpose eNB will be forwarded by source eNB.

If the switching request message that purpose eNB is received, the inside contain the RRC configuration information to UE, wherein may have RRC measurement configuration information, if being configured with UE in source eNB carries out MDT measurement, purpose eNB need to decide whether to continue into Row MDT measurement, only regional scope of the cell where current UE inside MDT configuration information, purpose eNB continue to UE hair The MDT report sent, does not need the MDT measuring configuration of release UE.Otherwise purpose eNB includes RRC information in switching response message The MDT measuring configuration of UE is discharged, which is transmitted to UE by source eNB.

If not including the configuration information element of MDT in the switching request message that purpose eNB is received, include tracking activation letter The other information and MDT type (perhaps information instruction) for ceasing element are when MDT type (or information instruction) instruction is needed to UE's When designated port is tracked, purpose eNB carries out the message of the designated port of UE according to the configuration of tracking active information Tracking, otherwise, purpose eNB ignores the tracking active information that switching request includes, and wrong will not track to UE.

If in the switching request message that purpose eNB is received including the configuration information element of MDT, when MDT type indicates to need When tracking to the designated port of UE, purpose eNB is according to the configuration of tracking active information to the designated port of UE Message is tracked, and otherwise, purpose eNB ignores the tracking active information that switching request includes, will not mistake to UE carry out with Track.

Step 305: source eNB sends switching command to UE.Message includes to be switched to all information of purpose eNB needs, Include encryption information, channel parameter etc..

After step 306:UE is with purpose cell synchronous, sends switching response message and give target eNB.Uplink and downlink data can It is transmitted with starting interface in the sky.

Step 307: purpose eNB transmitting path switching request message is to MME.It include mark of the UE in S1 interface in message, Target area identifies (abbreviation TAI), the purpose service PLMN mark (selected PLMN) in TAI comprising selection, under eNB is The information such as the tunnel number of row data distribution.

Step 308:MME transmitting path handover request ack message gives purpose eNB.Message includes mark of the UE in S1 interface Know, is the information such as the tunnel number that upstream data distributes comprising MME.

X2 handoff procedure terminates.

Embodiment two describes MME and the relevant information of MDT is sent to eNB, and the relevant information of MDT is arranged comprising MDT PLMN Table, MDT configuration information etc., when X2 switching, source eNB has selected new service PLMN, source eNB to determine whether to a MDT Configuration information element is sent to purpose eNB, and purpose eNB decides whether to continue to track according to the information element received.Fig. 4 institute Show that method may comprise steps of:

Step 401:MME sends MDT PLMN list to eNB.The information can be transmitted by following method:

Step 402:MME sends tracking active information to eNB.Track active information include TR, TRSR, TCE IP address, The interface of tracking, tracking depths also include MDT configuration information element, and MDT configuration information element includes the type of MDT, and MDT is surveyed The information such as the range of amount.The information can be transmitted by following method:

Step 403:eNB receives the measurement report of UE, according to the measurement report of UE, needs to be switched to UE on purpose eNB Face.There is X2 interface between source eNB and purpose eNB, source eNB initiates X2 handoff procedure.Source eNB sends switching request message to purpose ENB, source eNB are the service PLMN mark that UE selects purpose eNB to use above, and source eNB includes new in switching request message Service PLMN mark.Switching request message also includes the type of MDT.
