Abstract: This application provides a random access method and apparatus. The method may include determining, by a terminal, a service attribute of to-be-transmitted data, where the service attribute includes one or more of the following: a service type attribute, a service packet attribute, and a service latency attribute. The method may also include sending, by the terminal when the service attribute meets a preset condition for early data transmission, a random access request to a network device using a dedicated resource for the early data transmission. In this way, the early data transmission is initiated after the service attribute meets the preset condition for the early data transmission, so that a quantity of times for which the early data transmission is initiated is reduced, thereby saving resources. In addition, a success rate of the early data transmission can be improved.

Abstract: This application relates to wireless communications technologies, and in particular, to a random access device, method, and system. In a network device provided in this application, a processing module is configured to determine a same processing result for random access procedures initiated by N terminal devices in M terminal device sets, where M and N are positive integers; and a sending module is configured to send a same random access control message to the N terminal devices, where the random access control message indicates the same processing result determined by the processing module, the message includes terminal set identification information, and the terminal set identification information identifies the N terminal devices. The network device uses a same random access reject message to indicate the same processing result for the random access procedures to the N terminal devices.
