Abstract: This application relates to the field of communications technologies, and discloses a communication method and a communication apparatus, to reduce service delay due to uplink data cannot be directly sent by a terminal when the terminal is in an inactive state. The method in this application includes: receiving a first message from a first access network device; then releasing or suspending a configured dedicated signaling radio bearer SRB and resetting protocol entities corresponding to a configured data radio bearer DRB. The first message is used to indicate to a terminal to enter a radio resource control (RRC) inactive state, and the first message carries an identifier of the terminal in the radio resource control (RRC) inactive state and radio access network notification area (RNA) information.

Abstract: Embodiments of this application provide a communications method, apparatus, and system. The method includes: A terminal device receives first information sent by a network device, where the first information includes access control information of services with N service attributes, and N is an integer greater than or equal to 1; and the terminal device determines, based on a first service that currently needs to be initiated and the first information, whether the terminal device can initiate the first service, where the N service attributes include at least a non-public network service, and the first service is any one of the services with the N service attributes. Therefore, access control on the terminal device is implemented when there is a non-public network service.

Abstract: Embodiments of this application provide a communication method, a communications apparatus, and a storage medium. The communication method includes: sending, by a new master network device, a request to an original master network device, to request context information of a terminal device on the original master network device and an original secondary network device; and receiving the context information of the terminal device on the original master network device and the original secondary network device from the original master network device. This application can effectively simplify implementation steps of resuming a multi-connectivity mode by the terminal device, reduce signaling procedures, and shorten a delay, thereby improving network transmission efficiency.
