Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on the Chinese patent application with the application number of 202010791022.X and the application date of August 7, 2020, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is incorporated herein by reference.

technical field

The present application relates to the field of communication technologies, and in particular, to an MDT processing method, core network equipment, access network equipment and terminals.

Background technique

Minimization of Drive-Tests (MDT) is an automated drive-testing technology that configures ordinary users or commercial terminals through the network to collect and report measurement data. Compared with traditional drive test technology, MDT has the following advantages:

More labor-saving, ordinary users can participate, which can reduce the cost of manual road testing;

More comprehensive, road testing can also be performed in areas where test vehicles such as narrow roads and residential quarters cannot reach;

More timely, common terminal problems are reported in time.

Through MDT, coverage loopholes, excessive coverage, if coverage, and pilot pollution problems can be found. In addition, abnormal events, such as connection establishment failure, can be found. At the same time, based on the MDT results, cell coverage maps and cell handover area maps can be drawn. The concept of MDT design is to minimize the extra power consumption of the UE, fully rely on the existing measurement volume, and do not increase the additional measurement of the terminal. Also, maximize the availability of location information; to pinpoint problem areas.

MDT can be divided into two categories according to task tracking objects:

Management/area-based MDT (Management Based MDT): MDT data collection and reporting for subscribers within a specific range (such as cell ID, tracking area TA).

Signaling/user-based MDT (Signalling Based MDT): Designate a specific user for MDT data collection and reporting.

Both of the above two types can be implemented in Logged MDT (recorded MDT) or immediate MDT (real-time MDT) mode. logged MDT: MDT related measurement records in idle or inactive state; Immediate MDT: MDT related measurement and reporting in connected state.

The signaling-based MDT and the management/area-based MDT can be configured to the base station at the same time. In addition, if the base station has sent the Logged MDT configuration to the terminal, the base station will no longer retain the Logged MDT-related context, nor will it be transmitted between base stations. Logged MDT context.

But a new potential requirement in 5G or subsequent communication systems is that management/area-based MDT cannot cover signaling-based MDT. However, in the existing MDT configuration principle, the base station only configures MDT for the terminal according to its own state, and the terminal will apply the latest MDT configuration after receiving the new MDT configuration, so there may be management/area-based MDT covering signaling-based MDT. problem.
