Embodiment 1

[0093] In this embodiment, the source base station actively obtains the QoS measurement amount (in this embodiment, UE uplink and downlink throughput) and UE geographic location information, and the UE deletes the locally saved original UE side MDT measurement configuration information when a handover occurs, and Before the handover, the target base station sends the newly generated UE-side MDT measurement configuration information (indicating that the UE needs to locate geographic location information and report it to the base station) to the UE through a handover command.

[0094] The specific process of the embodiment of the present invention includes:

[0095] Step A1, when the source base station receives the base station side MDT measurement configuration information issued by OAM (indicating that UE uplink and downlink throughput and UE geographic location information need to be counted within the cell range covered by the base station), the source base station formulate...

Embodiment 2

[0103] In this embodiment, the source base station actively obtains the QoS measurement amount (in this embodiment, specifically, the uplink and downlink throughput of the UE), and the UE obtains the geographical location information of the UE and reports it to the source base station. When a handover occurs, the UE deletes the original UE-side MDT measurement configuration information, the target base station directly sends the original UE-side MDT measurement configuration information to the handover UE after handover.

[0104] The specific process of the embodiment of the present invention includes:

[0105] Step B1, when the source base station receives the base station side MDT measurement configuration information issued by OAM (indicating that UE uplink and downlink throughput and UE geographic location information are counted within the cell range covered by the base station), the source base station formulates the original UE side MDT measurement configuration informat...

Embodiment 3

[0114]In this embodiment, the UE obtains and reports the QoS measurement amount (specifically, UE uplink service data delay in this embodiment) and UE geographic location information, and the UE deletes the locally stored original UE-side MDT measurement configuration information when a handover occurs, And the target base station sends the newly generated UE-side MDT measurement configuration information to the UE through a handover command before the handover.

[0115] For the specific implementation manner of this embodiment, refer to the first and second embodiments above, and details are not repeated here.

Abstract

The invention discloses an MDT (minimization drive test) measuring method, MDT measuring equipment and an MDT measuring system. The MDT measuring method includes: a source base station stops MDT measuring of UE (user equipment) when determining that the user equipment UE switches to a target base station; and the target base station starts MDT measuring of the UE after determining that the UE switches successfully. The invention provides another MDT measuring method, which includes that the UE stops MDT measuring and stops reporting MDT measuring value to the source base station when being determined to switch from the source base station to the target station; the UE restarts MDT measuring and reporting the MDT value to the target base station after being determined to switch to the target base station successfully. During switching of the UE, the MDT measuring is stopped so as to avoid the problem of poor network optimizing effect due to inaccurate MDT measuring value during switching of the UE.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method, device and system for minimizing drive test (MDT). 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. In order to reduce the operation and maintenance cost of the network, it is hoped that the network configuration UE (User Equipment, user equipment) report method can be adopted to reduce the manual drive test work, that is, the MDT (Minimization Drive Test, minimized drive test) solution. In addition, it is also hoped to obtain wireless measurement information in areas that cannot be reached by ordinary drive tests through MDT measurements. [0003] In orde...
