Description

MDT processing method, core network equipment, access network equipment and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for processing MDT, a core network device, an access network device, and a terminal.

Background

Minimization of Drive Tests (MDT) is an automated Drive test technology for collecting and reporting measurement data by configuring a general user or a commercial terminal through a network. Compared with the traditional drive test technology, MDT mainly has the following advantages:

the labor is saved, and the cost of manual drive test can be reduced by the participation of common users;

more comprehensive, the test vehicles in narrow road sections, residential areas and the like can not reach the areas and can also be subjected to drive test;

and more timely reporting the problem of the common terminal in time.

Coverage holes, excessive coverage, coverage and pilot pollution problems can be found through MDT, abnormal events such as connection establishment failure can be found, and a cell coverage map, a cell switching area map and the like can be drawn based on the MDT result. The MDT design idea is to reduce the extra power consumption of the UE as much as possible, fully rely on the existing measurement quantity and not increase the extra measurement of the terminal. In addition, the usability of the position information is increased as much as possible; to accurately determine the problem area.

MDT can be divided into two categories by task trace object:

management/region-Based mdt (management-Based mdt): and MDT data acquisition and reporting are carried out aiming at the signed users in a specific range (such as a cell ID and a tracking area TA).

Signaling/user Based MDT (Signaling Based MDT): and appointing a specific user to carry out MDT data acquisition and report.

Both of the above two types can be realized by a Logged MDT (Logged MDT) or an immediatate MDT (real-time MDT) model. logged MDT: performing MDT related measurement record in an idle state or an inactive state; immedate MDT: and carrying out MDT related measurement and reporting in a connected state.

The signaling-based MDT and the management/area-based MDT may be simultaneously configured to the base station, and further, if the base station has transmitted the configuration of the Logged MDT to the terminal, the base station does not retain the context related to the Logged MDT any more, and does not transfer the context of the Logged MDT between the base stations.

But there is a recent potential need in 5G or subsequent communication systems that management/area based MDT cannot override signaling based MDT. However, in the existing MDT configuration principle, the base station configures the MDT to the terminal only according to its own state, and the terminal receives a new MDT configuration and applies the latest MDT configuration, so that there may be a problem that the MDT based on management/area covers the MDT based on signaling.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

Aiming at the problem that the MDT configuration mode in the prior art possibly has MDT based on management/area to cover MDT based on signaling, the embodiment of the invention provides at least two modes for ensuring that the MDT based on management/area does not cover the MDT configuration based on signaling. The first mode is as follows: the terminal ensures that the MDT based on management/area does not cover the MDT configuration based on signaling; the second way is: the management/area based MDT of the network side device does not override the signaling based MDT configuration.

For the first mode, as shown in fig. 1, an embodiment of the present invention provides a method for processing minimization of drive test MDT, which is applied to a terminal, and includes:

step 11, receiving configuration information of an MDT sent by a network device, where the configuration information includes a type of the MDT; the type of the MDT is MDT based on signaling, or the type of the MDT is MDT based on management/area;

and step 12, determining whether to ignore the configuration information according to the type of the current MDT of the terminal.

Wherein step 12 comprises:

For example, the terminal resides in the base station a and enters a connected state, and the core network sends the configuration information of the MDT to the base station a; the base station A sends the configuration information of the MDT to the terminal, and the type of the MDT is indicated in the configuration information of the MDT; the terminal enters an idle state, reselects to the base station B and establishes RRC connection, and if the terminal receives the configuration information based on the management/area MDT sent by the core network equipment and sends the configuration information to the terminal, the terminal ignores the configuration information, so that the MDT based on the management/area can not cover the MDT based on the signaling.

In summary, in the embodiments of the present invention, through the type of the MDT interaction between the base station and the terminal, it is ensured that the MDT based on management/area does not cover the MDT configuration based on signaling, so that the prepared measurement information of the tracking terminal can be ensured.

Correspondingly, for the first mode, an embodiment of the present invention further provides a method for processing minimization of drive test, MDT, applied to a network device, including:

step 31, receiving the state information of the MDT sent by the second device, where the state information of the MDT includes at least one of:

a time of signaling-based MDT configured for the terminal;

a duration of signaling-based MDT configured for the terminal;

the execution time of the signaling-based MDT configured by the terminal;

the remaining time of the signaling-based MDT that the terminal has configured.

It should be noted that the first device may be a target base station to which the terminal is handed over, or an auxiliary base station in a dual connectivity scenario, and the like, which is not specifically limited herein.

Further, the method further comprises:

Determining whether to configure management/area-based MDT to a terminal according to the state information of the MDT, including:

For example, the first device determines the remaining time of the signaling-based MDT configured by the terminal according to at least one of the time of the signaling-based MDT configured by the terminal, the duration of the signaling-based MDT configured by the terminal, the execution time of the signaling-based MDT configured by the terminal, and the remaining time of the signaling-based MDT configured by the terminal, and does not configure the management/area-based MDT to the terminal for the remaining time; further, after the configuration of the signaling-based MDT has expired, the first device may transmit the configuration information of the management/area-based MDT to the terminal at an appropriate time.

As an optional embodiment, in a case that the second device is a core network device, receiving the state information of the MDT sent by the second device includes:

Example 1

the core network sends an initial context establishing message to the base station B, wherein the initial context establishing message carries the state information of the MDT;

and based on the state information of the MDT, the base station B manages the configuration of the MDT of the terminal, and ensures that the MDT of the economic management/area does not cover the MDT based on the signaling.

As another optional embodiment, in the case that the second device is an access network device, receiving the status information of the MDT sent by the second device includes:
