Clock setting method, mobile terminal and storage medium based on sim module

Abstract

The invention discloses a clock setting method based on a SIM module, a mobile terminal and a storage medium. The method includes: detecting battery power, and judging whether the battery power is greater than a preset upper limit or less than a preset lower limit; When the terminal enables the SIM module, set the clock power supply of the SIM module to the default current configuration; detect the positive voltage and negative voltage of the clock signal of the SIM module, judge whether the maximum voltage is within the first preset range, and judge the minimum voltage at the same time. Whether the voltage is within the second preset range; if not at the same time, the clock supply current of the SIM module is set to a preset multiple of the currently set clock supply current configuration of the SIM module. The present invention dynamically sets the clock of the SIM module of the mobile terminal, so that the clock signal of the SIM module of the mobile terminal can work stably, ensures the normal communication of the SIM module of the mobile terminal, prevents the network from being disconnected due to communication failure, and provides convenience for users.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a clock setting method based on a SIM module, a mobile terminal and a storage medium. Background technique [0002] Calling is one of the most basic functions of a mobile terminal. The network must be used when making a call, and the medium connecting the mobile terminal to the network is the SIM (subscriber identification module) issued by the operator. The SIM module is used for network registration in the mobile terminal. Card / module; At present, the SIM module replacement card detection technology has been widely used in various mobile terminals, and the SIM module is common in the prior art, that is, the SIM module can be used in any mobile terminal with a SIM module interface . SIM modules are mainly used in GSM networks, W-CDMA networks and TD-SCDMA networks, but compatible modules can also be used in IDEN phones. There are also RUIM cards and UIM cards of CDMA2...

Problems solved by technology

In the prior art, in order to save power, the mobile terminal only needs to provide a clock signal for the SIM module when periodically polling the network status, and the stability of the clock signal is very important for the use of the SIM module, especially when When the battery voltage of the mobile terminal is high or low, the clock signal of the SIM module of the mobile terminal cannot be dynamically set in the prior art, so that the clock signal of the SIM module of the mobile terminal cannot work stably, resulting in the normal communication of the SIM module of the mobile terminal.
