Embodiment 1

[0048] This embodiment provides a power supply method for a SIM card, such as figure 2 shown, which includes:

[0049] S201. When the mobile terminal is in the power-on state, detect the data communication state between the main controller configured in the mobile terminal and the SIM card;

[0050] S202. If the data communication status is no communication, record the duration of no communication;

[0051] S203. When the duration reaches a preset threshold, stop supplying power to the SIM card, and detect the data communication status between the main controller and the SIM card;

[0052] S204. When detecting that the main controller sends data to the SIM card, control the main controller to connect to the VDD pin of the SIM card, so as to supply power to the SIM card.

[0053] Specifically, when the main controller stops supplying power to the SIM card, the SIM card is in an unavailable state. At this time, if the main controller has data to send to the SIM card, the sen...

Embodiment 2

[0060] This embodiment provides a storage medium, which stores a plurality of instructions, and the instructions are suitable for being loaded by a processor and executing any one of the power supply methods for a SIM card described above.

Embodiment 3

[0062] This embodiment provides a mobile terminal, such as image 3 As shown, it includes at least one processor (processor) 30 ( image 3 A processor 30 is taken as an example); a display screen 31 ; and a memory (memory) 32 may also include a communication interface (Communications Interface) 33 and a bus 34 . Wherein, the processor 30 , the display screen 31 , the memory 32 and the communication interface 33 can communicate with each other through the bus 34 . The display screen 31 is configured to display the preset user guidance interface in the initial setting mode. The communication interface 33 can transmit information. The processor 30 can invoke logic instructions in the memory 32 to execute the methods in the above-mentioned embodiments.

[0063] In addition, the above-mentioned logic instructions in the memory 32 can be implemented in the form of software function units and can be stored in a computer-readable storage medium when sold or used as an independent p...

Abstract

The invention discloses a power supply method for an SIM card, a storage medium, and a mobile terminal. The method comprises the following steps: when the mobile terminal is in a power-on status, detecting a data communication status between a master controller arranged on the mobile terminal and the SIM card; if the data communication status is a non-communicated status, recording a non-communication duration; and when the duration reaches a preset threshold, stopping the power supply to the SIM card. The method, the storage medium and the mobile terminal provided by the invention have the advantages that whether data communication between the master controller and the SIM card is continuously unavailable during the preset duration or not is detected, and the power supply to the SIM card is controlled according to a detection result, so that the power supply to the SIM card can be stopped when the SIM card is idle to save electric energy, and the continuous working time of a battery of the mobile terminal and the service life of the battery can be further prolonged.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a power supply method for a SIM card, a storage medium, and a mobile terminal method and system. Background technique [0002] With the development of technology, digital electronic devices, such as digital cameras, smart phones (smart phones), tablet PCs (tablet PCs) and mobile phones, etc., allow users to obtain required information anytime and anywhere in daily life. In the use of smart phones or mobile phones, the use of a mobile phone number usually needs to correspond to a Subscriber Identity Module (SIM) card to store the identification data of the user of the mobile phone service, and can Store SMS data and phone numbers. At the same time, smart phones or mobile phones need to provide power for the SIM card. [0003] At present, the power supply process for the SIM card by the mobile terminal is to start to supply power to the SIM card and load the...
