Abstract
The embodiment of the application relates to a method for realizing Minimization of Drive Test (MDT) under a dual-connection architecture, terminal equipment and network equipment, wherein the method comprises the steps that the terminal equipment receives measurement configuration of the MDT sent by an access network node; and the terminal equipment performs MDT measurement and/or records the MDT measurement result according to the MDT measurement configuration, and sends the MDT measurement result to the access network node. The embodiment of the application can realize MDT under a double-connection network architecture.
Description
The present application relates to the field of communications, and in particular, to a method, a terminal device, and a network device for implementing minimization of drive test under a dual connectivity architecture.
In order to understand the performance of the mobile network, the mobile network introduces a signal acquisition method called Minimization of Drive Tests (MDT), which has the core idea of enabling a plurality of user terminals to report their signal acquisition amount under the condition of acquiring terminal permission. On the premise that the number of terminals is sufficient, the network can quickly and economically acquire the network performance related information in the region, and the mode of collecting the network performance of the terminals in some target regions is called management-based MDT (management-based MDT). Hereinafter, MDT is also used to help the network collect network performance related data of a specific terminal, and this MDT collection manner is called signal-based MDT (signaling-based MDT). The MDT configuration file is directly sent to the terminal through a 5G core network control plane network element or a network manager, and the terminal finishes acquisition and reports the acquisition to the base station.
The target terminal signal acquisition state of the MDT may be in a connected state or an idle/inactive state. When the terminal is in a connected state and reports the measured acquisition quantity, the method is called an immediate MDT (immediate MDT), after the terminal receives an immediate MDT configured by a Mobility Management Entity (MME) or Operation Administration and Maintenance (OAM), the terminal uses a mechanism of connection state measurement reporting (measurement reporting), and when a measurement reporting condition (period or based on an event) is met, the terminal reports the measured quantity to a base station through the measurement reporting on a Uu interface.
The current technology does not support MDT under a dual connectivity architecture, and under a dual connectivity network architecture, a terminal device cannot receive MDT configuration of an auxiliary node and cannot report corresponding MDT measurement quantities.
