Patent Description:
In current network optimization of a mobile communication system, a drive-test is usually adopted to check whether a coverage quality of a network and system performance meet expected requirements of a design, that is, professional network-optimization personnel drive a measurement vehicle to move at random, during which a measurement terminal records an event and a measurement variable to be provided to an operator for decision-making of network-optimization.

Some or all of the units may be selected according to actual needs to achieve objectives of the solutions of the present disclosure.

In addition, various functional units in the embodiments of the present disclosure may be integrated in one processing unit, may be physical units existing separately, or two or more units may be integrated in one component.

Functions may be stored in a computer readable storage medium if the functions are implemented in a form of software functional units and sold or used as separate products. Based on such an understanding, an essential part, or a part contributing to the related art, or a part, of technical solutions of the present disclosure may be embodied in a form of a computer software product which is stored in a storage medium. The storage medium includes several instruction used to cause a computer device (which may be a personal computer, a server, or a network device, etc.) to perform all or a part of that steps of the method of various embodiments of the present disclosure. The aforementioned storage medium includes a variety of media capable of storing program codes, such as a USB disk, a mobile hard disk, a ROM, a RAM, a magnetic disk, an optical disc, and the like.

Claim 1:
A method of processing abnormality configuration of Minimization of Drive-Test , MDT, the method being perfomed by a base station and comprising:
receiving (<NUM>, <NUM>, <NUM>, <NUM>) first information related to MDT-measurement configuration sent by a network operation-administration-and-management entity or a network node of a core network, wherein the first information related to MDT-measurement configuration comprises at least MDT-tracking report information;
activating (<NUM>, <NUM>, <NUM>, <NUM>) an MDT-measurement execution object to perform MDT measurement if the MDT-measurement execution object satisfies an MDT measurement condition in the MDT tracking report information;
not activating (<NUM>, <NUM>, <NUM>, <NUM>) the MDT-measurement execution object to perform MDT measurement if the MDT-measurement execution object does not satisfy the MDT measurement condition in the MDT tracking report information;
wherein the MDT-measurement execution object comprises a user equipment ,UE,
wherein,
the method further comprises:
forwarding (<NUM>) the MDT-tracking report information to a target base station if the user equipment does not satisfy the MDT measurement condition and the base station knows that the user equipment hands over to the target base station, characterized in that,
after forwarding (<NUM>) the MDT-tracking report information to the target base station, the method further comprises:
sending, by the base station to the network operation-administration-and-management entity or the network node, information of failure of MDT-measurement configuration and information of forwarding the MDT-tracking report information to the target base station, wherein the information of failure of MDT-measurement configuration carries a cause for the failure of MDT-measurement configuration.
