Description

Method, terminal device and network device for realizing minimization of drive tests under dual-connection architecture

technical field

The present application relates to the field of communications, and more particularly, to a method, a terminal device, and a network device for realizing minimization of drive tests under a dual-connection architecture.

Background technique

In order to better understand the performance of the mobile network, the mobile network introduces a signal acquisition method called Minimization of Drive Tests (MDT, Minimization of Drive Tests). Its core idea is to enable many user terminals to report their signal acquisition volume. On the premise that the number of terminals is sufficient, the network can quickly and economically obtain information about network performance in an area. This method of collecting the network performance of terminals in certain target areas is called management-based MDT (management-based MDT). Since then, MDT is also used to help the network collect data related to network performance of specific terminals. This MDT collection method is called signal-based MDT (signaling-based MDT). The MDT configuration file is directly sent to the terminal through the 5G core network control plane network element or network management, and the terminal completes the collection and reports it to the base station.

The signal acquisition state of the target terminal of the MDT may be in a connected state or an idle/inactive state. Among them, when the terminal is in the connected state, the MDT method for reporting the measurement and collection volume is called immediate MDT (immediate MDT). After MDT, the terminal uses the mechanism of measurement reporting (measurement reporting) in the connected state. When the measurement reporting conditions (periodic or event-based) are met, the terminal reports the measurement amount to the base station through the measurement reporting on the Uu interface.

The current technology does not support the MDT under the dual-connection architecture. Under the dual-connection network architecture, the terminal device cannot receive the MDT configuration of the secondary node, and cannot report the corresponding MDT measurement quantity.
