Abstract: This application provides a paging message transmission method and relates to the field of communications technologies, to resolve a problem of waste of a downlink time-frequency resource. The method includes: determining, by a network device, that a communications device is in a beam update mode; then determining, by the network device, a second beam based on beam information reported by the communications device, where the beam information includes information about at least one receive beam, and the information about the at least one receive beam includes information about the second beam; and finally sending, by the network device, a paging message to the communications device over a first beam, where the first beam corresponds to the second beam. This application is applicable to a paging message transmission process.
