Embodiment Construction

[0049] In the future mobile communication system, it is hoped that by introducing a network self-optimization mechanism, manual participation in network planning and operation and maintenance will be reduced, and the network will automatically optimize parameters according to statistics to reduce network construction and operation costs. In order to reduce network operation and maintenance costs, it is hoped that a network configuration UE reporting method can be adopted to reduce manual drive test work, that is, a minimized drive test (MDT) solution. On the other hand, it is also desirable to obtain wireless measurement information in areas that cannot be reached by ordinary drive tests.

[0050] The purpose of MDT collection is for network operation optimization. If terminal equipment can only provide wireless signal measurement results but cannot provide location information or precise location information, it is difficult for operators to optimize the specific deployment lo...

Abstract

The embodiment of the invention discloses a method and equipment for feeding back MDT (Minimization Drive Test) measurement information. By utilizing the technical scheme proposed by the embodiment of the invention, network side equipment informs terminal equipment of a requirement on a precise position information record, so that when the current position reaches a corresponding requirement on the precise position information record, the terminal equipment carries out MDT measurement and reports the measurement result and position information, thus the problem of overlarge expenditure caused by the condition that the terminal equipment frequently triggers the position information record can be solved, and the air interface resource of the system is effectively saved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for feeding back MDT measurement information. Background technique [0002] In the existing technical solutions, MDT (Minimization Drive Test, minimized drive test mechanism) measurement is divided into Immediate MDT (instant type minimized drive test mechanism, IMD MDT) and Logged MDT (log type minimized drive test mechanism, LOG MDT) two types: [0003] Immediate MDT, the MDT measurement and reporting performed by the terminal device in the connected state, multiplexes the form of RRM (Radio Resource Management, radio resource management) measurement. Once the reporting conditions are met, the terminal device immediately reports to the eNB (evolved Node B, evolved base station) ) / RNC (Radio Network Controller, radio network controller) reports the measurement result. [0004] Logged MDT, the MDT measurement performed by the terminal device in the id...
