Description

A kind of MBMS minimum road test method and access device

Technical field

The present invention relates to the communications field, particularly relate to a kind of minimum road test method and the access device of supporting MBMS function.

Background technology

Special equipment is utilized to carry out cost and the complexity of artificial drive test in order to reduce operator, third generation partnership project (3GPP, Third Generation Partnership Projects) at universal land radio access web (UTRAN, Universal Terrestrial Radio Access Network, comprise base station NodeB and radio network controller (RNC)) and the universal land radio access web (E-UTRAN of evolution, Evolved Universal Terrestrial Radio Access Network, comprise evolution base station eNB) the version 10(Release-10 of system) start to introduce minimum road test (MDT, Minimization of DriveTest) function.Core net (the CN that UTRAN is corresponding, Core Network) comprise host-user server (HSS, Home Subscriber Server), Mobile Switching Center Server (MSC Server, Mobile Switching Centre Server), service GPRS Support Node (SGSN, ServingGPRS Support Node, GPRS-General Packet Radio Service-GPRS) etc.The core net CN that E-UTRAN is corresponding comprises host-user server HSS, mobile management entity (MME, Mobile Management Entity) etc.Minimum road test functional utilization subscriber equipment (UE, User Equipment, or be called terminal) automatically collect metrical information and be reported to wireless access network (RAN by chain of command (ControlPlane) signaling, Radio Access Network, RNC is referred to for UTRAN system, eNB is referred to for E-UTRAN system), Operation & Maintenance System (OAM is reported to again by wireless access network, Operation And Maintenance) tracking collect entity (TCE, TraceCollection Entity), for the network optimization, such as find and solve network coverage problem.

MDT function is divided into the MDT(Management based MDT based on management) and based on the MDT(Signaling based MDT of signaling).Based on the activation of MDT of management normally (for E-UTRAN system, below all with) OAM(Operation and Maintenance or claim network management system) send comprise MDT configuration tracking activate message (Trace session activation) to eNB, select suitable UE in the region (Area) that eNB specifies in this message, and described MDT configuration information is sent to the UE chosen.Activation based on the MDT of signaling sends by OAM the tracking comprising MDT configuration to activate message (Trace session activation) to HSS(Home Subscriber Server) measure to activate the MDT specifying UE, the MDT configuration information of described UE is sent to MME by HSS, the MDT configuration information of this UE is sent to eNB by MME, and eNB the most at last MDT configuration information sends to UE.MDT based on signaling uses IMSI International Mobile Subscriber Identity (IMSI usually, InternationalMobile Subscriber Identity) or international mobile station device identification (IMEI, International MobileStation Equipment Identity) specify certain UE, or add that area information is to limit the selection of UE.MDT based on management and the MDT based on signaling activates in message track reference (Trace Reference) information comprised from OAM, comprising public land mobile network (Public Land MobileNetwork, PLMN) information, by Mobile Country Code MCC (Mobile country code, MCC) and Mobile Network Code (Mobile Network code, MNC) composition.

MDT function is operated in Idle state according to it and is operated in connected state and can be divided into two kinds of mode of operations, is specially " record minimum road test (Logged MDT) " and " immediately minimum road test (immediateMDT) ".Record minimum road test refers to that UE (refers to RRC_IDLE state for E-UTRAN system in wireless heterogeneous networks idle condition; Cell _ paging channel state (CELL_PCH) and UTRAN Acceditation Area _ paging channel state (URA_PCH) are also comprised for UTRAN system).Report when collecting when configured condition meets and store correlation measurement information for receiving wireless access network (RAN) order request in the future, after wireless access network (RAN) receives described data, gather or be directly transmitted to TCE.Minimum road test refers to that UE (refers to RRC_CONNECTED state for E-UTRAN system in wireless heterogeneous networks connection status immediately; CELL _ DCH status (CELL_DCH) is referred to for UTRAN system) time collect correlation measurement information and when report meets report condition active upload to wireless access network (RAN), after wireless access network (RAN) receives report, gather or directly report passed to TCE.

In existing protocol version, MDT only supports to measure based on the MDT of clean culture (unicast) signal, but do not support the measurement based on multicast (multicast) signal, that is: the MDT function for MBMS is not supported, and on the other hand, prior art has provided some measuring amount measuring MBMS performance, such as multicast single-frequency network Reference Signal Received Power (MBSFN RSRP), multicast single-frequency network Reference Signal Received Quality (MBSFN RSRQ), Multicast Channel packet loss (MCH BLER).With reference to the description in 3GPP manuscript R1-135918, MBSFN RSRP is defined as the power linear mean value of MBSFN reference signal place Resource Unit (resource element) in measuring frequency bandwidth, MBSFN RSRQ is defined as the ratio of MBSFN RSRP and the instruction of acknowledge(ment) signal intensity, MBSFN BLER is defined as Cyclical Redundancy Check (CRC) result based on assessment multicast channel (MCH) transmission block, this value is the ratio in the measuring period, the denominator of ratio is the sum of MCH transmission block, and the molecule of ratio is the MCH transmission block number of crc error.These measurements can only untied in the subframe (subframe) of physics multicast channel (PMCH) and frequency (carrier) in terminal and carried out.

If terminal on certain frequency (such as certain MBSFN) accepts MBMS, then can measure the measuring amount of this frequency, if operator is further to the analysis of these measuring amount information, the actual deployment situation of MBMS can be known, such as judge whether to there is business cavity, whether exist and need for certain MBSFN(multicast single-frequency network) open and close some MBMS communities etc.

It can be seen from the above, in existing 3GPP version, MDT function does not support MBMS, secondly performing the MDT(management MDT based on management) when MBMS is measured, base station cannot judge which terminal supports MBMS, do not know which MBMS is terminal receiving, cannot judge the information such as the frequency at the business place that MBMS terminal is accepting simultaneously yet yet.This is because MBMS terminal does not report MBMS ability (MBMS capability) at present, therefore base station cannot know which terminal supports MBMS ability; Terminal also can not report the information such as the frequency of received business, and therefore the base station MDT that cannot configure based on frequency such as to measure at the task.In addition, record MDT in prior art and do not support allocating and measuring amount, terminal acquiescence after receiving configuration measures all measuring amount of protocol conventions, and MBMS measure in especially error rate BLER measure do not accepting cannot measure under corresponding MBMS, be therefore necessary that flexible configuration is to support MBMS.Finally, because MBSFN region can be overlapping, after the measured value that terminal provides is supplied to TCE, TCE cannot distinguish the measured value in different MBS FN region, and this problem does not provide in the prior art.

Below in conjunction with embody rule, the specific implementation process of said method is described.

Example one

For Fig. 2, illustrate based on management MDT(Management based) under (Immediate) immediately minimum road test process.This process comprises the steps 201a to 207a.

Step 201a: access device obtains terminal MBMS relevant information;

The method obtained can be terminal active reporting and or access device active obtaining.

Wherein, for the situation of terminal active reporting, terminal initiatively can carry MBMS information in the flow process of access network, this process as shown in Figure 3, for the flow process (with reference to agreement 36.331) that Radio Resource connects is set up in base station in prior art.

In addition, terminal also can carry MBMS information in RRCconnctionrequest message, as shown in Figure 4, in the RRC Reconfiguration Procedure of prior art, terminal can carry MBMS information to this process in RRCconnectionReconfigurationComplete message.

Or terminal, with process shown in Fig. 5, in the MBMS interesting indication flow process of prior art, initiatively carries MBMS information in MBMSInterestIndication message.

For the situation of access device active obtaining, access device also can initiatively start flow to obtain the MBMS information of terminal, as shown in Figure 6, for on the MBMS counting process base of prior art, access device can initiatively start this flow process for the MDT function of MBMS, and terminal carries MBMS information in MBMScountingresponse message.

Terminal and access device can use other and the mutual MBMS information of new flow process equally, such as, use new information by access device initiative reporting information by terminal, or terminal active reporting MBMS information.

Access device is kept in terminal contexts after obtaining terminal MBMS information.

Step 202a:EM triggers access device and activates trace session;

This example is (Immediate) MDT immediately, and as shown in Figure 2, webmaster sends and activates message, triggers and measures the MDT of MBMS.Network management configuration can adopt explicit configuration mode.

When explicit configuration: comprise MBMS in configuration and specifically measure requirement, such as, need the MBSFN zone list measured, to each MBSFN needing to measure, or also comprise multicast channel (MCH) list of needs measurement;

Concrete measuring amount parameter can also be comprised in configuration, such as each MBSFN region is needed to the MBSFN signal measured, further instruction need to measure certain/MBSFNRSRP in some MBSFN region and or MBSFN RSRQ, to in each MBSFN region, several need the multicast channel measured, indicate whether further to measure MCH BLER, think that the multicast channel MCH being configured with needs measurement just needs to measure MCH BLER as long as also can give tacit consent to;

Can also measuring period be comprised in configuration, measure the relevant configuration such as sum;

Step 203a: access device selects MBMS terminal;

The measurement that access device obtains according to step 202 requires (needing the MCH measured under needing the MBSFN of measurement and each MBSFN), and MBMS information (the MBMS ability of the terminal obtained from step 201, terminal interested and or the MBSFN that accepting, the business information etc. that terminal is just accepting), select suitable MBMS terminal.RSRP and RSRQ such as, in step 202 under certain MBSFN of webmaster requirement measurement, then access device can require the contextual information of inquiry terminal according to this, and selects suitable terminal.

Step 204a: access device configurating terminal MDT measures;

This example belongs to the mode based on MDT immediately, needs the measuring amount clearly measured during configuration, will need the MBSFN numbering measured, and measuring amount such as RSRP and RSRQ configures to terminal in this example.Increase new measurement such as M6.

Configuration can use RRC to measure Message Transmission, in the message for MBMS increases the measurement M6 that new field such as innovates, or new Message Transmission can be used to configure.

Step 205a:UE starts MDT immediately and measures;

UE measures according to configuration, to the measurement result of each measuring amount, adds corresponding MBSFN numbering and belonging MBMS district numbering (SA).

Such as according to configuration, UE measures RSRP and the RSRQ value of certain frequency under certain MBSFN, record described value after completing, add MBSFN numbering corresponding to this frequency upper and service area number information, the measured value under these information can help TCE to differentiate different MBSFN simultaneously.

Step 206a:UE measurement completes, access network report MDT measurement report;

According to prior art, when UE measures message feedback MDT measurement report by RRC;

Step 207a: the access device receiving the measurement report of UE selects suitable TCE equipment, and effective MDT measurement report is reported described TCE equipment.

This step uses prior art, measurement report is reported TCE equipment.MBSFN numbering and the information such as service area numbering of MBMS measured value and correspondence thereof is comprised in measurement report.

Example two

Still for such as Fig. 2, the process based on record (logged) MDT under management (Management based) is described.This process comprises the steps 201b to 207b.

Step 201b: access device obtains terminal MBMS relevant information

Particularly, above-mentioned steps 201b can reference example one step 201a.

Access device is kept in terminal contexts after obtaining terminal MBMS information.

Step 202b:EM triggers access device and activates trace session;

Particularly, above-mentioned steps 202b can reference example one step 202a.

Step 203b: access device selects MBMS terminal;

This example is record MDT, and as shown in Figure 2, webmaster sends and activates message, triggers and measures the MDT of MBMS.Network management configuration can adopt explicit configuration mode also can adopt the configuration mode of implicit expression.

When explicit configuration: comprise MBMS in configuration and specifically measure requirement, such as, need the MBSFN zone list measured, to each MBSFN needing to measure, or also comprise multicast channel (MCH) list of needs measurement;

Concrete measuring amount parameter can also be comprised in configuration, such as to each MBSFN needing to measure, further instruction need to measure MBSFN RSRP and or MBSFN RSRQ, to each multicast channel needing to measure, indicate whether further to measure MCH BLER, think that the multicast channel MCH being configured with needs measurement just needs to measure MCH BLER as long as also can give tacit consent to;

Can also measuring period be comprised in configuration, measure the relevant configuration such as sum;

When implicit expression configuration: webmaster only indicates the MDT needing to carry out MBMS to measure, access device and network side according to the measuring amount of making an appointment to terminal RSRP in receptible MBSFN region and or RSRQ measure, further the error rate (MCH BLER) that terminal in each MBSFN is just accepting MBMS is measured.

When optimizing, if the MBSFN region that terminal can receive is too much, can making an appointment, it is limited multiple only to measure, such as four MBSFN, and other MBSFN just no longer measures.

Step 204b: access device configurating terminal MDT measures;

When this example is the mode based on record MDT, can use explicit mode configurating terminal during configuration, such as configuration needs the MBSFN numbering measured, need the RSRP that measures and or the information such as RSRQ; Loggedmeasurementconfiguration message in RRC information can be used, in the message for MBMS increases new field, or new Message Transmission configuration can also be used.

Step 205b:UE starts record (logged) MDT and measures when entering Idle state;

UE measures according to configuration, to the measurement result of each measuring amount, adds corresponding MBSFN numbering and belonging MBMS district numbering (SA), to the MCH measured value under each MBSFN, adds corresponding MCH number information.

Such as according to configuration, UE measures RSRP and the RSRQ value of certain frequency under certain MBSFN, record described value after completing, add MBSFN numbering corresponding to this frequency upper and service area number information, the measured value under these information can help TCE to differentiate different MBSFN simultaneously.

Step 206b:UE measurement completes, access network report MDT measurement report;

According to prior art, when UE enters connected state, UE indicates this terminal to preserve MDT measurement report to Access Network; The access device obtaining MDT measurement result obtains MDT measurement report by the terminal obtains information (UEinformation flow process) of prior art.

Step 207b: the access device receiving the measurement report of UE selects suitable TCE equipment, and effective MDT measurement report is reported described TCE equipment.

This step uses prior art, measurement report is reported TCE equipment.MBSFN numbering and the information such as service area numbering of MBMS measured value and correspondence thereof is comprised in measurement report.

Example three

This example, for Fig. 7, illustrates based on the process of minimum road test immediately under signaling (Signaling based).This process comprises the steps 701a to 705a.

Step 701a: webmaster (EM) triggers minimum road test, sends MDT message to location register (HSS) network element.According to prior art, MDT configuration messages can be trace session activation (Trace SessionActivation) message.

Comprise MBMS in configuration and specifically measure requirement, such as, need the MBSFN zone list measured, to each MBSFN needing to measure, or also comprise multicast channel (MCH) list of needs measurement;

Concrete measuring amount parameter can also be comprised in configuration, such as to each MBSFN needing to measure, further instruction need to measure MBSFN RSRP and or MBSFN RSRQ, to each multicast channel needing to measure, indicate whether further to measure MCH BLER, think that the multicast channel MCH being configured with needs measurement just needs to measure MCH BLER as long as also can give tacit consent to;

Can also measuring period be comprised in configuration, measure the relevant configuration such as sum

Step 702a: location register (HSS) retrieves after UE is in attachment state, sends MDT configuration messages to the core network element at UE place.

Complete according to prior art, if under E-UTRAN network condition, described core network element is MME; If UTRAN network condition, described core network element is SGSN or MSC server; Such as, when core network element is MME, the message of carrying MDT configuration is location updating response (updatelocation answer).

Step 703a: core network element sends MDT configuration messages to base station.

According to prior art, if under E-UTRAN network condition, described base station is eNB, if UTRAN network, described base station is RNC;

If when E-UTRAN network, the message of the described MDT of carrying configuration is that initial context sets up request (Initial context setup request) message, if UTRAN PS territory, described in carry minimum road test configuration message be CN invoke Trace message;

Step 704a: access device obtains terminal MBMS relevant information

This step can reference example one step 201a;

Step 705a: base station receives the MDT configuration messages that core network element sends, checks whether terminal allows to perform MBMS and measure;

The MDT configuration information that base station obtains according to step 703, and the MBMS information that step 4 obtains, check whether terminal meets MDT and measure requirement.If terminal cannot meet, base station can stop this MDT and measure.

Such as configuring request requires that terminal measures MBMS, and terminal does not support MBMS, then base station stops this MDT and measures.

Such as configuring request requires that terminal measures the BLER of MCH under certain MBSFN, but terminal and lose interest in and or do not accept this MBSFN business, therefore cannot perform MDT and measure, in this case, base station can stop this MDT and measure.

Example four

The present embodiment, still for Fig. 7, illustrates based on record (logged) the minimum road test process under signaling (Signaling based).This process comprises the steps 701b to 704b.

Step 701b: webmaster (EM) triggers minimum road test, sends MDT message to location register (HSS) network element.According to prior art, MDT configuration messages can be trace session activation (Trace SessionActivation) message.

This example is record MDT situation, and network management configuration can adopt explicit configuration mode also can adopt the configuration mode of implicit expression.

When adopting explicit configuration: comprise MBMS in configuration and specifically measure requirement, such as, need the MBSFN zone list measured, to each MBSFN needing to measure, or also comprise multicast channel (MCH) list of needs measurement;

Concrete measuring amount parameter can also be comprised in configuration, such as to each MBSFN needing to measure, further instruction need to measure MBSFN RSRP and or MBSFN RSRQ, to each multicast channel needing to measure, indicate whether further to measure MCH BLER, think that the multicast channel MCH being configured with needs measurement just needs to measure MCH BLER as long as also can give tacit consent to;

Can also measuring period be comprised in configuration, measure the relevant configuration such as sum;

When adopting implicit expression configuration: webmaster only indicates the MDT needing to carry out MBMS to measure, access device and network side according to the measuring amount of making an appointment to terminal RSRP in receptible MBSFN region and or RSRQ measure, further the error rate (MCH BLER) that terminal in each MBSFN is just accepting MBMS is measured.

When optimizing, if the MBSFN region that terminal can receive is too much, can making an appointment, it is limited multiple only to measure, such as four MBSFN, and other MBSFN just no longer measures.

Step 702b: location register (HSS) retrieves after UE is in attachment state, sends MDT configuration messages to the core network element at UE place.

Complete according to prior art, if under E-UTRAN network condition, described core network element is MME; If UTRAN network condition, described core network element is SGSN or MSC server; Such as, when core network element is MME, the message of carrying MDT configuration is location updating response (updatelocation answer).

Step 703b: core network element sends MDT configuration messages to base station.

According to prior art, if under E-UTRAN network condition, described base station is eNB, if UTRAN network, described base station is RNC;

If when E-UTRAN network, the message of the described MDT of carrying configuration is that initial context sets up request (Initial context setup request) message, if UTRAN PS territory, described in carry minimum road test configuration message be CN invoke Trace message;

Step 704b: access device obtains terminal MBMS relevant information

This step can reference example one step 201a;

Step 705b: base station receives the MDT configuration messages that core network element sends, checks whether terminal allows to perform MBMS and measure;

The MDT configuration information that base station obtains according to step 703b, and the MBMS information that step 704b obtains, check whether terminal meets MDT and measure requirement.If terminal cannot meet, base station can stop this MDT and measure.Such as when explicit configuration, base station checks whether terminal meets explicit configuration one by one.Such as under implicit expression configuration, base station needs to check that institute surveys terminal whether satisfied configuration requirement of making an appointment.

Such as configuring request requires that terminal measures MBMS, and terminal does not support MBMS, then base station stops this MDT and measures.

Such as configuring request requires that terminal measures the BLER of MCH under certain MBSFN, but terminal and lose interest in and or do not accept this MBSFN business, therefore cannot perform MDT and measure, in this case, base station can stop this MDT and measure.

This step uses prior art, measurement report is reported TCE equipment.MBSFN numbering and the information such as service area numbering of MBMS measured value and correspondence thereof is comprised in measurement report.
