The invention discloses a different-network switching method and terminal based on an AP (application processor) in an Android system. When a mobile broadband network is switched to a wireless broadband network and an SIP (session initiation protocol) session is established, a PPP (point-to-point protocol) unit initiates a PPP dial and processes a PPP message, a switching control unit intercepts a PPP data message transmitted by the mobile broadband network, and the data message undergoes a tunnel encapsulation and then is transmitted to the wireless broadband network. When the wireless broadband network is switched to the mobile broadband network, an RIL (radio interface layer) interface redirects a link establishment request to the PPP unit, i.e., a whole switching process uses the PPP unit in the AP, and the switching control unit intercepts PPP data originally transmitted by the wireless broadband network and sends the PPP data to the mobile broadband network. According to the invention, the continuous operation connection is guaranteed without the PPP renegotiation authentication required in different-network switching and without the redistribution of IP addresses of the mobile terminal device.
