Abstract: Embodiments of this application provide a configuration method and apparatus. When indicating, by using an RRC connection release message, a terminal to enter an inactive state from a connected state, a network device may include, in the RRC connection release message, a configuration parameter allocated to the terminal in the inactive state. That is, the terminal receives the radio resource control RRC connection release message sent by the network device, where the RRC connection release message includes first information used to indicate a target configuration parameter. In this way, the terminal may enter the inactive state based on the RRC connection release message, and determine a context parameter of the inactive state based on the first information, so that the configuration parameter is properly allocated to the terminal in the inactive state.

Abstract: Various embodiments provide a resource allocation method and an apparatus. In those embodiments, a terminal device obtains a first parameter indicating a maximum service data volume to be provided by an access network device for a first service in a first time length; and determines, based on the maximum service data volume, a resource of a media access control protocol data unit MAC PDU, the resource being occupied by buffered data of the first service. In those embodiments, the terminal device determines, based on the maximum service data volume of the first service, the resource of the MAC PDU. Compared with a conventional method, the maximum service data volume of the first service is considered. This helps improve reasonableness of allocating the resource of the MAC PDU to the data of the first service.

Abstract: A random access method is provided including: a terminal side device obtains first uplink data from a first message buffer, wherein the first message buffer is a buffer specific to a first random access procedure, the first random access procedure is a procedure in which the terminal side device sends a first random access request, sends the first uplink data on a first uplink resource, and receives response information, and the response information is a first random access response to the first random access request or a response to the first uplink data. The terminal side device sends the first random access request to a network side device, and sends the first uplink data to the network side device on the first uplink resource. The terminal side device detects downlink control information, wherein the downlink control information indicates a resource of the response information.
