Abstract: Example subscription information configuration methods and a communications device are described. One example method includes receiving a first device identifier by a network device from a first terminal device in a first access mode and receiving a second device identifier from a second terminal device in a second access mode. The network device determines whether the first device identifier matches the second device identifier to identify legality of the first terminal device. If the first device identifier matches the second device identifier, it indicates that the first terminal device is a legal terminal device. The network device sends subscription information of the first terminal device to the first terminal device in the first access mode, so that the first terminal device successfully accesses a network by using the subscription information.

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.

Abstract: This application provides a communication method and apparatus. The method includes: a terminal sending first network information of a second network to a first network, where the first network information includes first indication information of the second network, and the first indication information indicating that the terminal requests to access the second network. The terminal performs onboarding delivery authentication of the second network through the first network. After onboarding delivery authentication of the second network succeeds, the terminal receives configuration information of the first network through the first network, and obtains a credential of the second network through the first network from an online sign-up server in the second network.

Abstract: This application provides a method for protecting a truncated parameter and an apparatus, and relates to the field of communications technologies, to ensure security of a truncated parameter in a transmission process. The method includes the following steps: A mobility management network element determines whether a terminal that accesses a network meets a preset condition, where the preset condition includes that the terminal uses a control plane CIoT 5GS optimization function. The mobility management network element sends, to the terminal when the terminal meets the preset condition, a downlink NAS message on which NAS security protection is performed by using a NAS security context, where the downlink NAS message includes a truncated parameter. This application is applicable to a truncated parameter transmission process.
