Abstract: This application provides a communication method and apparatus, to improve communication security. The method includes: receiving first system information from a network device, where the first system information includes a first signature; determining a first digest based on the first signature; determining a second digest based on the first system information; and if the first digest matches the second digest, storing or applying the first system information. In embodiments of this application, a signature is carried in a field of system information, so that both a terminal device that supports the signature and a terminal device that does not support the signature can complete decoding of the system information. Specifically, the terminal device that supports the signature may perform verification by using a signature obtained through decoding.

Abstract: A communication method and a communication apparatus. In the method, a terminal device can obtain first resource information according to a preset rule or from a network device, where the first resource information includes at least one of frequency domain position information, a cyclic prefix, or a subcarrier spacing; and receive a multicast broadcast service in a radio access control (RRC) idle state or an RRC inactive state based on the first resource information. According to the method, a resource used when the terminal device receives the multicast broadcast service in the RRC idle state or the RRC inactive state can be determined, so that the terminal device can receive the multicast broadcast service in the RRC idle state or the RRC inactive state.

Abstract: A communication method includes determining, by an access network device, that first information from a terminal device is not received in a first bandwidth part (BWP). The first BWP is an active BWP for the terminal device. The first BWP does not include common search space (CSS) used to transmit a system information block (SIB). The first information is associated with a system information update. The communication method also includes sending, by the access network device, updated system information to the terminal device in the first BWP in response to determining that the first information is not received.

Abstract: A paging method includes: determining, by an access network device or a core network device, a paging cycle based on type information of a terminal, and sending first information based on the paging cycle, where the first information is used to page the terminal. The paging cycle is determined as 2.56 s according to the type information indicating that the terminal is REDCAP UE, so that the REDCAP UE can perform monitoring in the paging cycle of 2.56 s, receive emergency broadcast in time, and obtain energy saving gains. In some situations, a paging method includes receiving first information comprising information of a paging cycle for a terminal, and determining, according to type information of a camped cell on which the terminal is currently camped, whether to use PTW in monitoring paging in accordance with the first information.

Abstract: This application pertains to the field of communication technologies, and provides a communication method and apparatus, to implement false base station detection. A false base station may attack a terminal in a denial of service manner, and consequently, the terminal cannot access the false base station after selecting the false base station, in other words, the terminal fails to set up a connection to a cell. In this case, if a first message indicates that a first terminal fails to set up a connection to a cell, it may be determined, based on the first message, that a false base station attack exists in the cell, to implement false base station detection.

Abstract: Examples of message transmission methods and apparatus are described. In one example, a message transmission method includes that a first network device receives a first message from a terminal device, where the first message includes a resume cause value and an integrity check code. The integrity check code is generated based on the resume cause value, the terminal device is in an inactive state, and the resume cause value is a resume cause indicated by a higher layer or a radio resource control (RRC) layer. The first network device sends a second message to a second network device, where the second message includes the resume cause value and the integrity check code. The second network device is a network device that stores a context of the terminal device.
