Abstract: This application provides a communication method, a communication apparatus, and a communication system. The method includes: obtaining a security policy corresponding to a quality of service flow identifier (QFI), where the security policy includes an integrity protection policy and/or a confidentiality protection policy; and performing, according to the security policy, security protection on a first data radio bearer (DRB) corresponding to the QFI. According to the technical solutions provided in this application, data security protection on a user plane at a QoS flow/DRB granularity can be implemented.

Abstract: A vehicle-to-everything terminal provides a vehicle-to-everything server with a security credential that can prove an identity of the vehicle-to-everything terminal, and requests the vehicle-to-everything server to apply for a certificate for the vehicle-to-everything terminal. The security credential may be a token preconfigured in the vehicle-to-everything terminal, or may be a digital signature of the vehicle. The vehicle-to-everything server performs identity verification on the vehicle-to-everything terminal based on the security credential. After the verification succeeds, the vehicle-to-everything server selects a proper certificate server to apply for a certificate for the vehicle-to-everything terminal.

Abstract: A software upgrade management method, a server, a terminal, an apparatus, and a storage medium are provided. The method includes: obtaining, by a server, an upgrade package; determining, by the server, a target upgrade mode for a terminal, where the target upgrade mode includes one of a server-determined upgrade mode, a terminal-determined upgrade mode, or a negotiated upgrade mode; and sending, by the server, the upgrade package to the terminal and performing, based on the target upgrade mode, a software upgrade procedure of the terminal. According to this solution, unmanned and automated scheduling of an upgrade can be implemented.

Abstract: This application provides a wireless communication method and apparatus. The wireless communication method includes: A first device obtains first information, where the first information includes a correspondence between first customer premise equipment and at least one first terminal device, and a correspondence between the first terminal device and at least one second terminal device. The first device configures the first information on a second device, where the first information is used by the second device to verify that a received service packet is a service packet sent by the first terminal device to the second terminal device by using the first customer premise equipment. Therefore, accuracy of service packet transmission of an industrial terminal device can be ensured, an industrial terminal or customer premise equipment can be prevented from being attacked to some extent, a loss caused by the attack on the device is reduced, and information security of the industrial terminal device in an industrial field network and an entire industrial field network is improved.

Abstract: A vehicle-to-everything (V2X) abnormal behavior detection method applied to a vehicle communications system that includes a V2X sending terminal, a V2X receiving terminal, and a V2X server. The method includes that the V2X receiving terminal receives a V2X message from the V2X sending terminal. The V2X receiving terminal determines, according to an abnormal behavior detection policy, that the V2X message is an abnormal message. The V2X receiving terminal sends a report message including the V2X message to the V2X server.
