Abstract: A local area network (LAN) communication management method includes obtaining, by an access and mobility management function (AMF) network element, registration area information of the terminal, the LAN identifier (ID) of the terminal, and the service area information corresponding to the LAN ID, determining, by the AMF network element, LAN communication area information of the terminal based on the registration area information of the terminal and the service area information corresponding to the LAN ID, sending, by the AMF network element, LAN information of the terminal to the terminal, where the LAN information of the terminal includes the LAN ID and the LAN communication area information of the terminal, and managing, by the terminal, LAN communication of the terminal based on the LAN information.

Abstract: A vaporizer device includes a vaporization unit for heating the smoke oil to generate an aerosol, a battery for supplying power to the vaporization unit, a housing connected to one end of the vaporization unit and accommodating the battery and a mouthpiece connected to the other end of the vaporization unit and used for inhaling the aerosol generated by the vaporization unit. The vaporizer device further includes a rotating part provided on the outside of the housing to rotate relative to the housing. By turning the rotating part, a user can relieve anxiety and stress. This indicates that the vaporizer device has an improved pressure relief effect. An annular knob is slidable toward a printed circuit board (PCB), so that a light-emitting diode (LED) lamp is controlled to change color.
