Abstract: This application discloses a call method and system, and a related apparatus. When a specific condition is met (for example, a callee fails to be paged), a network device forwards, to a VoIP server, a first call request to a target number, where the first call request is a call request initiated by a calling terminal to the target number, and the target number has been subscribed to a call forwarding service. Then the VoIP server parses a forwarding message from the network device to obtain a called number, searches, based on the called number, for the called terminal associated with the called number, and initiates a VoIP call to the called terminal, so that the callee in an out-of-service state (for example, there is no signal of an operator network or the callee is in an airplane mode) can still receive the call request from the caller.

The terminal disconnects from a 5G network in a first 5G serving cell when the terminal activates a dual connectivity function, and re-establishes a connection to the 5G network in a second 5G serving cell.

Abstract: In a battery charging system (100), a charger (110) and a smart battery (160) enhance safety in recharging a cell (180) in the smart battery (160) by a power supply (130) of the charger (110). The smart battery (160) is communicable with the charger (110). If a communication failure occurs, the charger (110) disconnects the power supply (130) from the smart battery (160). The smart battery (160) and the charger (110) share the same symmetric encryption key for encrypting and decrypting message data, allowing one party to determine if the other part is an authentic one. When the smart battery (160) finds that the charger (110) is not authentic, or vice versa, the power supply (130) and the cell (180) are disconnected.
