Problems solved by technology

In order to make the mobile terminal thinner, the technical solution adopted in the prior art is: the SIM card is arranged on the side of the mobile terminal, so that the user can insert or pull out the SIM card when the mobile terminal is turned on normally, but, If the mobile terminal is reading or writing data to the SIM card when the SIM card is inserted or pulled out, the SIM card will be damaged

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. The following examples are only used to illustrate the present invention, but should not be used to limit the scope of the present invention.

[0015] see figure 1 , figure 1 It is a flow chart of the method for detecting SIM card hot plugging in the first embodiment of the present invention, and the method of the present embodiment includes the following steps:

[0016] Step S101: detecting the magnetic field strength of the magnetic field generated by the magnet arranged on the SIM card holder;

[0017] In step S101, when the SIM card is inserted into the SIM card holder or the SIM card is pulled out from the SIM card holder, the SIM card holder needs to be moved for a displacement, and the magnet arranged on the SIM card holder moves along with the movement of the SIM card holder. Therefore, what this embodiment detects is the magnetic fie...

Abstract

The invention discloses a mobile terminal and a method thereof for detecting hot swapping of a subscriber identity module (SIM) card. The method comprises the steps of detecting the magnetic field intensity of a magnetic field produced by a magnet arranged on a SIM card holder, presetting a threshold value, judging whether the magnetic field intensity is lower than or equal to the threshold value or not, determining that the SIM card is inserted into the SIM card holder if a judgment result is yes, determining that the SIM card is pulled out of the SIM card holder if the judgment result is no. Through adopting the manner, the mobile terminal can effectively avoid the SIM card from being damaged due to hot swapping.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a mobile terminal and a method for detecting hot plugging of a SIM card. Background technique [0002] At present, with the continuous development of science and technology, the appearance of mobile terminals such as mobile phones is becoming more and more fashionable, and the thinning of mobile terminals has become a trend. In order to make the mobile terminal thinner, the technical solution adopted in the prior art is: the SIM card is arranged on the side of the mobile terminal, so that the user can insert or pull out the SIM card when the mobile terminal is turned on normally, but, If the mobile terminal is reading or writing data to the SIM card when the SIM card is inserted or pulled out, the SIM card will be damaged. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a mobile terminal and a method for detec...
