Mobile terminal realizing hot plug of SIM card and SIM card hot plug method

Abstract

The invention relates to a mobile terminal realizing hot plug of a SIM card and a SIM card hot plug method. The mobile terminal comprises a baseband processor, an antenna connected with the baseband processor through a radio frequency circuit, a memory connected with the baseband processor and a SIM card holder. The mobile terminal is characterized in that the SIM card holder is provided with an electronic switch; and in operation, the electronic switch can trigger low level or high level by drawing or plugging the SIM card, and further trigger software operating on the baseband processor to carry out the operation of drawing the SIM card or plugging the SIM card. The mobile terminal and the method mainly solve the technical problems that the prior mobile terminal software regular detecting method cannot find the operations of the drawing and the plugging of the SIM card in real time, and easily causes misoperation of a user; and the proposal realizes the hot plugging and drawing of the SIM card of the mobile terminal, ensures that the mobile terminal can correctly identify the operation of the drawing or the plugging of the SIM card under a startup state, and ensures normal operation of the mobile terminal.

Description

technical field [0001] The invention relates to a mobile communication terminal and a SIM card, in particular to a mobile terminal and a SIM card hot plugging method for realizing hot plugging of the SIM card. Background technique [0002] With the rapid development of personal mobile communication, mobile terminals are getting smaller and thinner, and the requirements for structural design are getting higher and higher. The structural design of many mobile terminals requires that the SIM can be plugged and unplugged in a power-on state, that is, the mobile terminal supports hot plugging of the SIM card. [0003] At present, the general technologies that support the hot swapping of mobile terminal SIM cards are: [0004] The mobile terminal software regularly reads and writes the SIM card (generally, the inspection period is 5-10 seconds). When the SIM card is pulled out, the mobile terminal software finds that the SIM card cannot be read and written, that is, the SIM card ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a mobile terminal and SIM card hot-swapping method for realizing SIM card hot-swapping, which mainly solves the problem that the existing mobile terminal software timing detection method cannot find the pulling-out and inserting actions of the SIM card in real time, which may easily cause user For the technical problem of misoperation, this solution realizes the hot-swapping of the SIM card of the mobile terminal, ensuring that the mobile terminal can correctly identify the action of pulling out or inserting the SIM when the mobile terminal is turned on, and ensures the normal operation of the mobile terminal
