Embodiment 1

[0049] Such as figure 1 As shown, taking the E-UTRAN system as an example, the process of realizing MDT activation includes the following steps:

[0050] Step 101, the operation management and maintenance (OAM, Operation Administration and Maintenance) tracking system sends a tracking session activation message to the eNodeB through the network element management system (EMS, Element Management System), and the tracking control parameters in the message include the location service key indicator attributes;

[0051] Step 102, the eNodeB saves the received tracking control parameters, and activates the tracking session;

[0052] In step 103, the eNodeB inquires about the device capability of the UE, and the device capability includes key indicators of the UE's location service; the UE returns its own device capability, including the key indicator of the UE's location service;

[0053] Step 104, the eNodeB checks whether the UE's location service key indicator matches the locat...

Embodiment 2

[0063] As shown in Figure 2, taking EPC as an example, the process of implementing MDT activation includes the following steps:

[0064] Step 101, the OAM tracking system sends a tracking session activation message to the HSS through the EMS, and the tracking control parameters in the message include the location service key indicator attributes;

[0065] Step 202, the HSS receives the tracking session activation message sent by the EMS, and saves the tracking control and configuration parameters therein;

[0066] From step 203 to step 204, the UE initiates an attach request to the eNodeB, and the eNodeB forwards the UE's attach request to the MME;

[0067] Step 205, after receiving the attachment request from the eNodeB, the MME sends the location update request of the UE to the HSS;

[0068] Step 206: After receiving the location update request from the MME, the HSS returns a location update response carrying the tracking control and configuration parameters to the MME.

Abstract

The invention discloses a method and a system for activating an MDT (Minimization of drive test). According to the invention, positioning service key indicator attribute is configured to all UE (user equipment), and only the MDT of the UE conforming to the positioning service key indicator attribute is activated. The MDT process of the UE is linked with the UE positioning service activating process so as to ensure that the report of the position information is realized based on the MDT process.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for realizing the activation of minimization of drive tests (MDT, Minimization of Drive Tests). Background technique [0002] At present, the use of MDT is a fast and effective way to optimize the coverage of the mobile communication network. The mobile communication network can activate the MDT of the user equipment (UE, User Equipment), so that the UE can collect and report network performance data. [0003] The network performance data reported by the UE needs to correspond to the location information, so as to be helpful for network optimization of the mobile communication network. In order to be able to report location information, the UE first needs to obtain its own location information. Currently, the techniques for UE to obtain location information mainly include: [0004] 1. Cell ID technology [0005] This technology relies on the mobile communi...
