Publication number: 20220053421Abstract: A communication method, apparatus, and system may include terminal device that receives first information from a core network device, where the first information is used to indicate whether the terminal device is to use a power-saving paging discontinuous reception cycle. The terminal device determines a paging discontinuous reception cycle of the terminal device based on the first information. Therefore, the terminal device avoids always selecting a shortest cycle as the paging discontinuous reception cycle, so that the paging discontinuous reception cycle determined by the terminal device is more appropriate, and power saving of the terminal device is facilitated.Type: ApplicationFiled: October 29, 2021Publication date: February 17, 2022Inventors: Lili ZHENG, Qinghai ZENG, Hongping ZHANG, Haibo XU, Yiru KUANG

Publication number: 20220015189Abstract: 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.Type: ApplicationFiled: September 27, 2021Publication date: January 13, 2022Inventors: Lili ZHENG, Qinghai ZENG, Hongping ZHANG
