Abstract: Disclosed are a method for determining an access method of a mobile terminal, a storage medium, and a mobile terminal. A database comprising APN types and APN access identifiers is pre-stored in a mobile terminal, such that when a SIM card is inserted into the mobile terminal, the APN type and the APN access identifier corresponding thereto can be searched in the database according to information about the SIM card, thereby determining that the access method of an operator corresponding to the SIM is VoLTE or VoWiFi, distinguishing between VoLTE and VoWiFi, reducing the probability of access failure of the mobile terminal.

Abstract: The disclosure provides a method for reducing radiation and a mobile terminal. The method comprises: detecting whether a current operating mode of the mobile terminal is a voice call mode or a data communication mode; and if the current operating mode of the mobile terminal is the voice call mode, transmitting by an AP side a preset first AT command to a modem to control the modem to restore a maximum transmit power for normal operation; if the current operating mode of the mobile terminal is the data communication mode, transmitting by the AP side a preset second AT command to the modem to control the modem to reduce the maximum transmit power.

Abstract: Embodiments of the present disclosure are directed to a radio frequency (RF) parameter processing method, a related device, a mobile terminal and a storage medium. The RF parameter processing method includes obtaining an RF parameter, performing a calibration process on the RF parameter to obtain a target RF parameter, wherein the target RF parameter comprises a target dynamic RF parameter, backing up the target dynamic RF parameter into a predetermined partition, and upon detecting a setting information, injecting the target dynamic RF parameter stored in the predetermined partition into an activated partition.
