The embodiment of the invention provides a mobile terminal operation method and a mobile terminal. The method comprises the following steps: when the mobile terminal is in a wireless network connection state, determining a first change of the acceleration of the mobile terminal, a second change of the position of the mobile terminal and a third change of the wireless network signal; If the first variation, the second variation, and the third variation meet the target conditions, the network connection is switched from the wireless network to the mobile network. If the first variation, the second variation, and the third variation meet the target conditions, the mobile terminal is in the scene of getting on and off the elevator, and the wireless network signal is poor in the process of getting on and off the elevator, so the mobile terminal switches from the wireless network connection to the mobile network connection, and the automatic switching is realized without manual switching ofthe user, and the stability of the network connection can be maintained, and the user's use experience can be improved.
