Abstract: This application provides a fake network device identification method and a communications apparatus. An uplink message sent by a terminal device is forwarded to a first network device via a second network device. After receiving the uplink message, the first network device generates a downlink message for the uplink message, performs security processing on the downlink message based on first time information, and/or sends the downlink message to the second network device. The second network device sends, to the terminal device, the downlink message on which the security processing is performed. The terminal device performs security verification on the received downlink message, and/or identifies whether the second network device is a fake network device. This helps improve communication security.

Abstract: This application provides a communication method and a communication apparatus. The method includes: A target access network device determines that a first terminal device is handed over from a source access network device to the target access network device; and sends first information to the first terminal device, where the first information indicates a first packet header compression context, and the first packet header compression context is for compressing or decompressing a packet header of a data packet. In this application, the target access network device sends, to the first terminal device, the first information indicating the first packet header compression context, so that in a handover scenario, the first terminal device can correctly decompress a subsequently received data packet with a compressed packet header. This helps improve communication reliability.

Abstract: A terminal device determines that local first system information is abnormal in the case of any of the following: a quantity of times of sending first signaling is greater than or equal to a first preset threshold within first preset duration; a time length in which a first service is unavailable is greater than or equal to a second preset threshold; a change trend of a tag value of a same system information block is abnormal; or a quantity of changes in a tag value of a same system information block is greater than or equal to a third preset threshold within second preset duration. The terminal device receives, from an access network device, second system information that is used to update the local first system information. Therefore, the terminal device can determine as soon as possible whether the terminal device is being attacked by a rogue base station.

Abstract: This application provides a method for handling a radio link failure, a terminal device, and a network device. The method includes: sending, by a terminal device, duplicated data packets to a network device on a first carrier and a second carrier; and sending, by the terminal device, RLF indication information to the network device in accordance with determining that an RLF event occurs on at least one of the first carrier and the second carrier, where the RLF indication information is used to indicate that the RLF event occurs on the first carrier, the second carrier, or the first carrier and the second carrier. The foregoing technical solution can optimize handling of the radio link failure.
