Problems solved by technology

[0009] However, the current protocol does not specify whether to perform MDT measurement configuration if the UE does not reside within the MDT measurement range, or the serving cell to which the UE is currently attached is not within the MDT measurement range

Embodiment Construction

[0036] In order to improve the existing MDT measurement mechanism and implement corresponding processing operations based on the MDT measurement range indication where the UE is located, in the embodiment of the present invention, when the mobility management entity (MME) determines that the UE accesses the cell under the jurisdiction of the base station, it obtains the preset MDT Measure the configuration parameters, and send the MDT measurement configuration parameters to the above-mentioned base station, instructing the base station to send the obtained MDT measurement configuration parameters to the above-mentioned UE when determining that the UE is located in the specified MDT measurement range, and notify the UE based on the received MDT measurement configuration parameters to perform MDT measurements. Correspondingly, when the base station determines that the UE accesses the local jurisdiction cell, it obtains the preset MDT measurement configuration parameters from the ...

Abstract

The invention discloses an indicating method, a device and a system of mean down time (MDT) measurement in order to perfect an existing MDT measurement mechanism. The method includes: a mobility management entity (MME) ensures that user equipment (UE) is connected into a controlled area of an evolved node B (eNB) and sends a configuration parameter of an MDT measurement to the eNB, and the eNB determines whether the UE is located in a predetermined MDT measurement scope or not. If the UE is located in the predetermined MDT measurement scope, the MDT measurement parameter is dispatched. Otherwise, the MDT measurement parameter is not dispatched. Therefore, when the UE meeting the selection requirement of operation and maintenance (OAM) is not located in the predetermined MDT measurement scope, the eNB can avoid dispatching the MDT measurement parameter so as to save signaling expenses. When the UE moves into the predetermined MDT measurement scope, the eNB dispatches the MDT measurement parameter to the UE so as to ensure that the UE can measure and report MDT measurement timely and further ensure performance and service quality of a system. Meanwhile, a corresponding device and a corresponding system are provided.

Description

technical field [0001] The present invention relates to the communication field, in particular to an indication method, device and system for MDT measurement. Background technique [0002] 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. At present, in order to reduce the operation and maintenance cost of the network, it is hoped to adopt the method of network configuration UE reporting to reduce the work of manual drive test. On the other hand, it is also hoped to obtain wireless measurement information in areas that cannot be reached by ordinary drive test. In the R10 protocol of the Long Term Evolution (LTE) system, it has been determined that Minimization Drive Test (MDT) adopts a control pla...
