Embodiment 1

[0056] This preferred embodiment overcomes the current shortcoming of using a fixed period for log (LOG) recording for all neighboring cells, and proposes a method for performing LOG measurement and recording according to UE measurement capability (measurement period), thereby improving the overall performance of MDT.

[0057] Figure 4 is a schematic diagram of the minimization drive test method according to a preferred embodiment of the present invention, such as Figure 4 As shown, the schematic diagram includes the following steps.

[0058] Step S402, the terminal enters the connected state, in the RRC_CONNECTED state;

[0059] Step S404, receiving and saving the MDT measurement configuration information, the UE receiving and saving the LOG configuration information LoggedMeasurementConfiguration pushed by the network side, where LoggingInterval is an optional information element;

[0060] Step S406, the UE returns to the idle state to complete the camping and starts the...

Embodiment 2

[0067] Figure 5 is a schematic flow chart of the MDT information method of the preferred embodiment of the present invention, such as Figure 5 As shown, the steps of the method for recording MDT information proposed in this preferred embodiment are described in further detail:

[0068] Step S502, RRC_CONNECTED state, the UE receives the MDT configuration message LoggedMeasurementConfiguration sent by the network, and saves it in the local variables VarLogMeasConfig and VarLogMeasReport of the UE, and records the RPLMN that resides at this time;

[0069] In step S504, the UE leaves the connected state and returns to the idle state to camp normally. First, it starts the required neighbor cell measurement according to the quality of the serving cell. The measurement of the specified frequency point and cell must be completed within the specified period. Start the LOG recording process when the RPMN and AreaConfiguration conditions are met at the same time;

[0070] Step S506,...

Abstract

The present invention discloses a method and device for minimizing drive tests, wherein the method includes: a terminal determines a measurement period for minimizing drive tests of one or more cells according to its own capabilities, and performs the one or more cells according to the measurement period. Minimize drive test measurement; the terminal performs log recording after the measurement is completed, which solves the problem of minimizing the storage of multiple redundant information of the drive test MDT and the inability to record the changes of adjacent cells in real time, and improves the overall performance of the MDT.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for minimizing drive testing. Background technique [0002] At present, compared with traditional drive tests, Minimization of Drive Tests (MDT for short) has many advantages, such as: it can reduce the cost of drive tests, shorten the optimization cycle, save energy and reduce emissions, and can collect data that cannot be collected by traditional drive tests. The measurement information of the whole area (such as narrow roads, forests, private places, etc.), thereby reducing the network optimization and maintenance costs of mobile communication operators. But in practical application, there are also many deficiencies. [0003] The protocol (36.133) stipulates the minimum measurement capability of the UE, that is, the longest measurement cycle interval. Like frequency adjacent cell measurement (Table 1) and UTRA measurement (Table 2): [0004] Table 1...
