Problems solved by technology
[0004] However, due to the repair operation of the crystal resonator when connecting to the previous network standard, there will be signal deviation in the generated clock signal. When the network standard is switched, the signal between the clock signal with signal deviation and the reference signal of the target network standard When the deviation exceeds the repair ability of the crystal resonator itself, the signal deviation between the clock signal with signal deviation and the reference signal of the target network standard cannot be repaired, that is, the network standard switching occurs due to the inability to achieve signal synchronization between the clock signal and the reference signal In the case of failure, it affects the user's experience on the mobile terminal

The embodiment of the present application discloses a network standard switching method, device, storage medium and mobile terminal. The method includes: when a network standard switching event is detected, generating a crystal oscillator refresh command; restarting the crystal resonator according to the crystal oscillator refresh command; based on the first signal generated by the restarted crystal resonator and the target network standard sent by the base station Signal synchronization is performed on the reference signal, so as to switch the current network standard to the target network standard. In the embodiment of the present application, by adopting the above-mentioned technical solution, when the network standard is switched, the crystal oscillator is restarted to the initial state, and the signal offset generated by the crystal oscillator in the previous network standard is eliminated, and the problem existing when the network standard is switched is solved. The problem that the difference between the reference signal and the first signal generated by the crystal oscillator cannot be repaired ensures the successful switching of the mobile terminal network standard.
Description
technical field [0001] The embodiments of the present application relate to the technical field of mobile terminals, and in particular, to a network standard switching method, device, storage medium, and mobile terminal. Background technique [0002] With the continuous development of electronic technology and communication technology, a mobile terminal can support multiple network standards, such as 2G (Second Generation, second-generation mobile communication technology), 3G (3rd-Generation, third-generation mobile communication technology) and 4G (4rd-Generation, fourth-generation mobile communication technology) and other network standards. When the mobile terminal is in different application states or in different locations, it can switch between different network standards. [0003] The connection between the mobile terminal and the base station is based on high-frequency electromagnetic waves, wherein the high-frequency electromagnetic waves are generated by digital ...
