Abstract

The invention discloses a minimized drive test (MDT) method and equipment and belongs to the field of communication. The MDT method comprises the following steps of: acquiring an MDT measuring result and the position information of user equipment (UE) which executes MDT, wherein the position information is obtained by control plane (CP) positioning; and associating the MDT measuring result with the position information of the UE, and acquiring association information. By the embodiment of the invention, the accuracy of the position information in the MDT measuring result is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and equipment for minimizing drive testing. Background technique [0002] In the current network optimization of mobile communication systems, drive testing is usually used to check whether the network coverage quality and system performance meet the expected design requirements, but the drive testing requires operators to invest a lot of manpower and material resources to complete. At present, 3GPP (3rd Generation Partnership Project, the third generation mobile communication cooperation organization) officially introduced the MDT (Minimization of Drive Tests) function in the R10 version, in which MDT requires UE (User Equipment, user equipment) to be in the connection state and idle (idle) state Record the measurement results such as network conditions and location information at the time of recording, and report the measurement results to the network side at an appropriate t...
