Embodiment 1

[0111] Such as Figure 7A As shown in , OAM configures an IMSI to participate in MDT measurement and the geographical area for measurement, that is, the UE corresponding to the IMSI is required A MDT measurements are performed in cell1, cell2, and cell3. UE A An RRC connection establishment request is initiated to cell4, and cell4 and cell1 belong to the same base station.

[0112] Step 1a: The EMS sends the MDT measurement configuration parameters to the HSS;

[0113] Step 1b: UE in IDLE state A Initiate an RRC connection establishment request to eNB1;

[0114] Step 2: eNB1 and UE A After establishing the RRC connection, send an initial terminal message (initial UE message) to the MME;

[0115] Step 3: The MME sends an Update Location Request (Update Location Request) message to the HSS to request the HSS to update the location of the UE in the network;

[0116] Step 4: After the HSS receives the update location request, it sends an update location answer (Update Locat...

Embodiment 2

[0122] Such as Figure 7B As shown, UE A A connection to the network has been established. The OAM configures an IMSI to participate in the MDT measurement and the geographical area where the measurement is performed, that is, the UE in the cell list is required to perform the MDT measurement in cell1, cell2, and cell3. The IMSI corresponds to the UE A .

[0123] Step 1: UE A Establish a connection with the network through eNB1, and the UE's current serving cell is cell 4;

[0124] Step 2: EMS sends a trace activation (trace activation) message to HSS, which carries MDT measurement configuration parameters;

[0125] Step 3: After receiving the tracking activation message, the HSS sends an insert subscriber data (insert subscriber data) message to the MME, carrying MDT measurement configuration parameters in the message;

[0126] Step 4: MME determines the measurement range of MDT as cell1, cell2 and cell3 according to the MDT measurement configuration parameters;

[012...

Embodiment 3

[0131] Such as Figure 7C As shown in , OAM configures an IMSI to participate in MDT measurement and the geographical area for measurement, that is, the UE corresponding to the IMSI is required A MDT measurements are performed in cell1, cell2 and cell3. UE in connected state A S1 handover is initiated, the target cell is cell 4, and cell1 and cell4 belong to the same base station.

[0132] Step 1: UE establishes a connection with the network through eNB 1;

[0133] Step 2: EMS sends trace activation message to HSS, which carries MDT measurement configuration parameters;

[0134] Step 3: After receiving the trace activation message, the HSS sends an insert subscriber data message to the MME, in which the MDT measurement configuration parameters are carried;

[0135] Step 4: MME determines the measurement range of MDT as cell1, cell2 and cell3 according to the MDT measurement configuration parameters;

[0136] Step 5: The MME judges that any cell in the MDT measurement cell...

Abstract

The invention discloses a method for sending Minimization Driving Test(MDT) measure configuration parameter, a system and equipment thereof which are used to solve the problem that network side configuration terminal UE can not carry out MDT measure when needed, relating to the wireless communication technical field. The method comprises the following steps: Mobile Management Entity (MME) receives terminal MDT measure configuration parameter sent by Home Subscriber Server (HSS); MME determines whether cell list information in the MDT measure configuration parameter contains the cell information of the base station to which the terminal belongs; if so, MME sends the MDT measure configuration parameter to the base station to which the terminal belongs. According to the invention, the problem that UE can not carry out MDT measure is solved.

Description

technical field [0001] The present invention relates to the field of wireless communication, and in particular to a method, system and equipment for delivering configuration parameters for minimum drive test measurement. Background technique [0002] In the future mobile communication system, it is hoped that by introducing a network self-optimization mechanism, manual participation in network planning and operation and maintenance will be reduced, and the network will automatically optimize parameters according to statistics to reduce network construction and operation costs. In order to reduce network operation and maintenance costs, it is hoped that a network configuration terminal (UE) report method can be adopted to reduce manual drive test work, that is, a minimized drive test (MDT) solution. On the other hand, it is also hoped that MDT can obtain wireless measurement information in areas that cannot be reached by ordinary drive tests. [0003] According to the report...
