Description
Technical Field
The present invention relates to communications technologies, and in particular, to a method, an apparatus, and a storage medium for minimization of drive tests.
Background
The minimization of drive tests (Minimization of Drive-tests, MDT) is an automated drive test technology introduced by UMTS/LTE for collecting and reporting measurement data by configuring a common user/commercial terminal through a network. Compared with the traditional drive test technology, the MDT has the following advantages:
1. the labor is saved, the participation of common users can be reduced, and the cost of manual drive test can be reduced;
2. more comprehensive: the road test can be performed in areas where test vehicles cannot reach, such as narrow road sections, residential communities and the like;
3. More timely: and the problem of the common terminal is reported in time.
Problems such as coverage holes, excessive coverage, weak coverage, pilot pollution and the like can be found through the MDT, and abnormal events such as connection establishment failure can be found, and meanwhile, a cell coverage map, a cell switching area map and the like can be drawn based on an MDT measurement result. The MDT design concept is to reduce the extra power consumption of the UE as much as possible, fully depend on the existing measurement, and do not increase the extra measurement of the terminal. The availability of the position information is increased as much as possible so as to accurately locate the problem area.
MDT can be divided into two classes by task tracking object:
1. management/zone based MDT (Management Based MDT): MDT data acquisition and reporting are carried out on subscribers in a specific range (such as Cell ID, TA and the like);
2. signaling/user based MDT (Signalling Based MDT): specific subscribers (e.g., based on IMSI, IMEI-SV, IMEI-TAC, etc.) are designated for MDT data collection and reporting.
Both types can be realized by recording a minimization of drive side (Logged MDT) or an immediate minimization of drive side (immediate MDT) mode, wherein the Logged MDT is used for carrying out MDT related measurement record in an idle state, and then entering a connection state and meeting reporting conditions for re-reporting; the immediate MDT is used for MDT related measurement and reporting under the connection state.
In order to cope with the current explosive mobile data flow increase, mass equipment connection and various new services and application scenes which are continuously emerging, 5G is generated. In order to meet the application scenario and key technology capabilities defined by the international telecommunications union (International Telecommunication Union, ITU), 5G defines multiple dual connectivity architectures, i.e. LTE air interface and 5G new air interface provide air interface connection for UE simultaneously, these dual connectivity architectures include not only the Option 3 series accessing EPC, LTE as a master node, NR as a slave node, but also the Option7 series accessing NGC, NR as a slave node, and further include the Option 4 series accessing NGC, NR as a master node, and ehte as a slave node.
However, since the technology related to MDT is limited to a single connection scenario, how to support MDT in a 5G dual connection scenario is a yet to be solved problem.

Detailed Description
For a more complete understanding of the nature and the technical content of the embodiments of the present invention, reference should be made to the following detailed description of embodiments of the invention, taken in conjunction with the accompanying drawings, which are meant to be illustrative only and not limiting of the embodiments of the invention.
Firstly, taking an operation 3a architecture defined by 5G as an example, as shown in fig. 1, a UE accesses a core network EPC through an LTE eNB (base station), and according to service requirements, the LTE eNB may add an NR gNB (base station) capable of serving the UE to the UE, so that the UE may transmit data on two links simultaneously. According to the 5G standard conclusion, both the LTE base station and the NR base station can send RRC signaling, the RRC signaling of the LTE base station can be borne on SRB1 and SRB2, the NR base station is borne on SRB3, and the LTE base station and the NR base station can issue independent measurement configuration. That is, the measurement configuration sent by the base station serving the UE in two different formats to the UE may be different, for example, the LTE base station measures FR1 related information and the NR base station measures FR2 related information. Thus, if MDT is applied to a dual connectivity architecture, collecting MDT measurements from only 1 link is not comprehensive. In addition, the MDT configuration includes not only the UE side but also the base station side, from which some measurement results, such as throughput information of the user, need to be collected.
Therefore, how to issue MDT configuration and collect relevant measurement results under the dual connectivity architecture is a problem that is not yet involved in the current 5G dual connectivity scenario. The embodiment of the application provides a solution to the problem, and aims to solve the problems of MDT configuration issuing, data reporting and signaling interaction between base stations under a double-connection architecture.
