  • Publication number: 20220030444
    Abstract: Embodiments of this application provide a communication method, apparatus, and system. The method includes: A terminal device receives first information from a first network device or a second network device, and determines, based on the first information, that it is allowable that the terminal device sends MDT information to the first network device. When it is allowable that the terminal device sends the MDT information to the first network device, the terminal device sends the MDT information to the first network device. This prevents the terminal device from sending the MDT information to the first network device immediately after obtaining the MDT information and avoids disclosure of a network coverage status, thereby effectively and securely using the MDT information.

  • Publication number: 20220015189
    Abstract: This application provides a communication method and apparatus, to determine a DRX cycle. The method includes: receiving data in an active time of a current DRX cycle; when a DRX inactivity timer of the current DRX cycle expires, determining a type of a next DRX cycle depending on whether at least some data received in the active time is associated with a DRX short cycle, where if the at least some data is not associated with a DRX short cycle, the next DRX cycle is a DRX long cycle, or the type of the next DRX cycle is the same as that of a DRX cycle previous to the current DRX cycle. When the DRX inactivity timer expires, the type of the next DRX cycle can be more flexibly determined, and may not necessarily be a DRX short cycle. This can save power of a device to some extent.
