  • Publication number: 20220393963
    Abstract: This application provides a method and an apparatus for configuring minimization of drive-tests MDT. The method for configuring MDT includes: A terminal device receives first MDT measurement configuration information and first indication information from a first network device. The terminal device learns, based on the first indication information, whether a type of first MDT configured by the first network device for the terminal device is signaling based MDT or management based MDT. Further, after establishing a connection to a second network device, the terminal device sends second indication information to the second network device, and reports the type of the first MDT that has been configured for the terminal device. The management based MDT overwrites signaling based MDT previously configured by the first network device for the terminal device can be avoided, thereby increasing a possibility that the management based MDT does not overwrite the configured signaling based MDT.

  • Patent number: 11523468
    Abstract: Example communications systems, methods and network devices are described. One example method includes sending a first message by a first access network device to a core network device to enable the core network device to send a second message to a second access network device, where the first message includes an identity of the second network device. The first message is used to request for X2 transport network layer (TNL) configuration information of a third network device, and the third network device is a network device that has established an X2 connection to the second network device. The first network device receives the X2 TNL configuration information of the third access network device from the second access network device. Therefore, a network device connected to a control plane of a core network can obtain TNL addresses of more network devices that are not connected to the control plane of the core network.
