Abstract: A configuration data update method is provided. The method includes: When configuration data for a terminal apparatus is first configuration data, where the first configuration data includes a first restriction indication and an empty closed access group CAG list, the first restriction indication is used to indicate the terminal apparatus to access a network through a closed access group CAG, an access and mobility management function apparatus configures the terminal apparatus to be in a state in which the terminal apparatus is allowed to access the network not only through a CAG in the CAG list. When the configuration data for the terminal apparatus is updated to second configuration data, where a CAG list in the second configuration data is not empty or does not include the first restriction indication, the access and mobility management function apparatus sends the second configuration data to the terminal apparatus.

Abstract: Embodiments of this application provide a method and an apparatus for detecting a false base station. The method includes: A network device sends system information to a terminal device, where the system information includes a first signature of the system information and a first timestamp, and the first timestamp identifies time at which the network device generates the first signature. The network device receives private information from the terminal device. The network device signs the private information of the terminal device by using a private key corresponding to the network device, to obtain a second signature. The network sends the second signature to the terminal device. According to the foregoing method, the terminal device can accurately verify whether the terminal device is attacked by a false base station, to improve communication security.

Abstract: This application provides a method for controlling a connection between a terminal and a network, and an apparatus. The method includes: receiving, by a terminal, a packet filter; and discarding, by the terminal, an uplink data packet matching the packet filter. Based on this solution, a connection can be blocked near a source (that is, the connection is blocked from the terminal), to reduce traffic exchanged between the terminal and a user plane network element. Compared with an existing technical solution, the terminal implements traffic control to reduce a quantity of uplink data packets sent to the user plane network element, thereby reducing load of the user plane network element.
