Description

A method, device and storage medium for minimizing drive test

technical field

The present invention relates to communication technology, in particular to a method, device and storage medium for minimizing drive testing.

Background technique

Minimization of Drive-tests (MDT) is an automated drive-test technology introduced by UMTS/LTE that configures common user/commercial terminals through the network to collect and report measurement data. Compared with traditional drive test technology, MDT has the following advantages:

1. More labor-saving, the participation of ordinary users can reduce the cost of manual drive testing;

2. More comprehensive: Road tests can also be carried out in narrow road sections, residential areas and other areas that cannot be reached by test vehicles;

3. More timely: Report any problems with ordinary terminals in time.

Coverage holes, excessive coverage, weak coverage, and pilot pollution can be found through MDT. In addition, abnormal events such as connection establishment failures can be found. At the same time, cell coverage maps and cell handover area maps can be drawn based on MDT measurement results. The concept of MDT design is to minimize the extra power consumption of the UE, fully rely on the existing measurement, and not increase the additional measurement of the terminal. Maximize location information availability to pinpoint problem areas.

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

1. Management Based MDT (Management Based MDT): MDT data collection and reporting for subscribers within a specific range (such as Cell ID, TA, etc.);

2. Signaling Based MDT (Signalling Based MDT): Specify a specific user (such as based on IMSI, IMEI-SV, IMEI-TAC, etc.) to collect and report MDT data.

Both of the above two types can be realized by recording the minimized roadside (Logged MDT) or immediately minimizing the roadside (immediate MDT) mode. The logged MDT is to perform MDT related measurement records in the idle state, and then enter the connected state and meet the reporting conditions It is to report again; immediate MDT is to perform MDT related measurement and report in the connected state.

In order to cope with the current explosive growth of mobile data traffic, massive device connections, and various new services and application scenarios emerging, 5G has emerged as the times require. In order to meet the application scenarios and key technical capabilities defined by the International Telecommunication Union (ITU), 5G defines a variety of dual-connection architectures, that is, LTE air interfaces and 5G new air interfaces provide air interface connections for UEs at the same time. Access to EPC, LTE as the primary node, NR as the secondary node Option 3 series, also includes access to NGC, eLTE as the primary node, NR as the secondary node Option7 series, also includes access to NGC, NR as the primary node, eLTE as the secondary node The Option 4 family of nodes.

Detailed ways

In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

First, take the Options 3a architecture defined by 5G as an example. As shown in Figure 1, the UE first accesses the core network EPC through an LTE eNB (base station). According to service requirements, the LTE eNB can add an NR gNB ( base station), so that the UE can transmit data on the two links at the same time. According to the conclusion of the 5G standard, both the LTE base station and the NR base station can send RRC signaling, the RRC signaling of the LTE base station can be carried on SRB1 and SRB2, and the NR base station can be carried on SRB3, and the LTE base station and the NR base station can issue independent measurement configuration. That is to say, the measurement configurations sent to the UE by two base stations of different standards serving the UE at the same time may be different. For example, the LTE base station measures FR1-related information, and the NR base station measures FR2-related information. Therefore, if MDT is applied to a dual-connection architecture, it is not comprehensive enough to collect MDT measurement results from only one link. In addition, the MDT configuration includes not only the UE side but also the base station side, and some measurement results, such as user throughput information, need to be collected from the base station side.

Therefore, how to issue MDT configurations and collect relevant measurement results under the dual-connection architecture is a problem that has not yet been covered in the current 5G dual-connection scenario. The embodiment of the present invention proposes a solution to this problem, aiming at solving the problems of MDT configuration distribution, data reporting and signaling interaction between base stations under the dual connection architecture.

When the reporting condition is satisfied, the UE reports the measurement result (Measurement Report) on the terminal side to the master base station.

Here, the first measurement result specifically includes: a measurement result at the base station side and/or a measurement result at the terminal side.

2) The measurement process of the secondary base station for the base station side is as follows: the secondary base station receives the base station configuration information in the second configuration information sent by the primary base station; performs MDT measurement based on the base station configuration information, and obtains the measurement result of the base station side.

The measurement process of the secondary base station for the terminal side is as follows:

The secondary base station sends an RRC connection reconfiguration request (RRC Connection Reconfiguration) to the UE, including the MDT configuration (MDT configuration);

The UE returns RRC Connection Reconfiguration Complete (RRC Connection ReconfigurationComplete) to the secondary base station;
