Abstract

The embodiment of the invention provides a method and a device for MDT (Minimization of Drive Test) measurement. The method includes the steps of: when MDT is the region-based MDT, and an OAM (Operation Administration Module) obtains an MDT task, sending a task request for establishing the MDT task to a CC (Call Control) module; judging whether the task identifier of the MDT task does not exists and the configuration parameter of the MDT task meets an audit condition by the CC module, wherein the task identifier is used for uniquely identifying the MDT task, and when the judgment result is yes, the CC module selects a user terminal positioned in the configuration cell of the MDT task for configuration. According to the method and device, the success rate of MDT measurement is improved.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and more specifically relates to a method and device for minimizing drive test measurement. Background technique [0002] In the current network optimization of mobile communication systems, drive testing is widely used to check whether the network coverage quality and performance meet the expected design requirements. Traditional road testing usually uses a dedicated test vehicle equipped with test terminals, measurement equipment and some additional tools, such as network parameter measurement equipment, spectrum analyzer, etc., and is done manually. [0003] In order to reduce the operation and maintenance cost of network optimization, shorten the optimization cycle, and obtain more comprehensive network coverage and performance measurement data, the Minimazation of Drive Tests (MDT) technology is introduced. measurement and collection to obtain the information needed f...
