Problems solved by technology

[0003] For terminals that do not support hot-swapping, random SIM card hot-swapping operations are likely to burn the user's SIM card and bring losses to the user
More importantly, if the SIM card is unplugged or a new SIM card is reinserted, the terminal cannot detect the status of the SIM card in time, resulting in that the network resources cannot be released in time after the SIM card is unplugged, or when a new SIM card is inserted. After the SIM is installed, the new network cannot be searched, but the new network must be manually restarted after the terminal is manually restarted, which obviously affects the user experience

Embodiment Construction

[0042] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the method for supporting hot swap in the present invention.

[0044] The method for supporting hot swap proposed in this embodiment includes:

[0045] Step S10, receiving a signal that the SIM card is inserted or pulled out;

[0046] In this embodiment, the preferred way to receive the signal of SIM card insertion or extraction is: a signal trigger is set right behind the card slot where the SIM card is installed to form a small switch for front and rear PUSH-PUSH, or a small switch in the SIM card slot Set a signal trigger at the bottom to form a small UP-DOWN switch; when...

Abstract

The invention relates to a SIM card hot plugging method, a device and a system; when a SIM card plugging signal is received, is the SIM card is determined to be unavailable, then the SIM card is initialized; if the SIM card is available, then power off treatment is carried out for a contact of the SIM card; network resource is released according to the state of the SIM card, or re-initialize the search network resource according to the SIM card state; a terminal needs not to be reset after the SIM card is plugged in so as to re-initialize the SIM card, thus improving user experience; in addition, when the SIM card is pulled out, the contact of the SIM card is powered off, so the SIM card is hard to burn.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method, device and system for hot plugging and unplugging of SIM cards. Background technique [0002] In mobile phone terminal products, when we replace the SIM (Subscriber Identity Module, Subscriber Identity Module) card, we usually turn off the power supply before replacing it. And in the conventional terminal design, the SIM card slot is generally designed under the battery, so we must remove the battery when replacing the SIM, so the problem of hot swapping of the SIM card is generally not involved. However, with the rise of electronic products such as PAD (Personal Access Device, personal ultra-thin computer) products and vehicle-mounted modules, the usage scenarios of users have changed, and the design of mobile terminals has also changed. We can find that for PAD products, the SIM card slot is not designed under the power supply, but on the side of the ter...
