Method and system for implementing drive test

摘要

A method and system for implementing a drive test are provided in the present document. The method includes: a mobility management entity sending activation message including measurement configuration information of Minimization of drive test (MDT) to a base station; after receiving the activation message, if determining that it is appropriate for a corresponding UE to perform a corresponding MDT measurement, the base station sending the measurement configuration information to the UE. With the present document, a MDT configuration information interaction between a core network and the base station can be effectively implemented in a communication system, which enables the base station to better select an appropriate UE according to local information and enables the base station to utilize measurement information reported by the UE to achieve an object of MDT, thereby reducing maintenance and operation costs of the current communication network and enhancing the network performance.

1. A method for implementing a drive test, comprising:
a mobility management entity sending activation message carrying measurement configuration information of Minimization of drive test (MDT) to a base station, wherein the measurement configuration information comprises an MDT measurement type and an MDT measurement content but without an identification of a specific User Equipment (UE) for MDT measurement; after receiving the activation message, the base station determining whether a UE is appropriate to perform a corresponding MDT measurement, and if yes, the base station sending the measurement configuration information from the mobility management entity to the UE, so that the UE performs the MDT measurement based on the measurement configuration information; wherein the activation message comprises: a handover request message; and wherein: the MDT measurement type comprises one or two of the following types: an immediate report type and a log report type, wherein:
if the MDT measurement type comprises the immediate report type, the measurement configuration information further comprises: a report trigger event, a report interval and a report amount; andif the MDT measurement type comprises the log report type, the measurement configuration information further comprises: a log record interval and a log configuration duration.
