Problems solved by technology

In the prior art, the in-position detection switch is controlled by timing adjustment to generate a disconnection trigger signal SIM_DCT to realize the hot-swapping protection of the SIM card, which has low reliability and sometimes damages the SIM card interface during the hot-swapping process of the SIM card.
[0004] In addition, in the prior art, for a terminal inserted with a SIM card supporting NFC (Near Field Communication, short-range wireless communication) technology, when the terminal is turned off, due to the signal transmission path and power supply of the SIM card socket The channels have been disconnected, so that the SIM card has no power supply and cannot perform information interaction, so the terminal cannot realize the NFC card swiping function

Abstract

An embodiment of the invention provides SIM (subscriber identity module) card hot plug protection method and terminal, and SIM card in-place power-down swiping method and terminal. The SIM card hot plug protection method includes: if first effective level triggered by a first signal generation switch of an SIM card socket is detected, generating a power-down control signal according to the first effective level; and powering down the SIM card socket according to the power-down control signal. The first effective level is trigged when an SIM card moves to a first position of the SIM card socket and touches the first signal generation switch during insertion, or the first effective level is triggered when the first SIM card moves to a second position of the SIM card socket during pulling. Compared with the prior art using timing adjustment schemes, the methods are higher in reliability.

Description

technical field [0001] The invention relates to communication technology, in particular to a SIM card hot-swapping protection method and a terminal for swiping the SIM card when the SIM card is in place. Background technique [0002] With the continuous development of smart phones, terminals are developing in the direction of large battery capacity and thinness, and more and more terminals adopt the solution of built-in batteries. The structure of the built-in battery makes it easier for mobile phone users to pull out or insert the Subscriber Identity Module (SIM card for short) from the SIM card holder. Regardless of whether the terminal supports hot swapping of the SIM card, the user may mistakenly pull out or insert the SIM card from the SIM card holder when the terminal is turned on. [0003] The biggest problem in the SIM card hot-swapping process is that the SIM card holder will randomly contact the non-power signal of the SIM card when it is not powered off, resultin...
