摘要： Embodiments of this application provide a paging message transmission method and a related device. The method mainly includes: receiving a first paging message from a core network device, where the first paging message includes a first indication corresponding to a terminal, and the first indication is used to indicate that the terminal supports latency-sensitive paging; determining a first paging carrier group corresponding to the first indication, where the first paging carrier group includes a portion of a plurality of paging carriers of a network side device; and paging the terminal on the paging carrier in the first paging carrier group. During implementation of the embodiments of this application, paging carriers are grouped, and different groups of paging carriers correspond to different paging configurations, so that different paging cycles in a cell can be supported, and paging requirements of both a short-latency and a deep-coverage terminal can be satisfied. According to the method provided in the embodiments, a network coverage capability is improved. The method may be applied to an internet of things, for example, MTC, the IoT, LTE-M, and M2M.

摘要： This application provides a cell establishment method and apparatus. The method includes: receiving, by a relay node, first downlink information sent by a base station, where the first downlink information includes cell configuration information of a first cell, and the first cell is a cell of the base station; and establishing, by the relay node, a second cell based on the cell configuration information, where the second cell serves as extended coverage of the first cell, and a cell global identifier and/or a physical cell identifier of the second cell are/is the same as those/that of the first cell. According to this application, the relay node may be used as extended coverage of any cell of the base station, to avoid complexity of operation, administration and maintenance caused by the relay node as an independent cell.

摘要： This application provides a key update method, a device, and a storage medium. After determining that a key needs to be updated, a network device sends, to user equipment, a first message used for releasing an RRC connection, where the message carries an indication used to indicate that the key is to be updated. After receiving the first message, the user equipment releases the RRC connection, and may determine that a release cause is that the key needs to be updated. In this case, the user equipment actively initiates an access process, obtains a new security configuration to complete updating the key, and does not need to wait for data to be uploaded or paging of the network device to perform access, thereby effectively shortening a disconnection time of the user equipment. In addition, the network device does not need to page the user equipment, thereby saving radio resources on a network side.
