Abstract
The invention provides a method and device of hot plug detection and a mobile terminal, and relates to the development technology of mobile terminals. A hot plug detecting switch which is opened when a subscriber identity module (SIM) card exists in an SIM card connector and is closed otherwise, or is closed when the SIM card exists in the SIM card connector and is opened otherwise is arranged. When the hot plug detecting switch is changed from being opened into being closed or from being closed into being opened, a hot plug detecting unit is confirmed that the hot plug phenomenon exists, hot plug treatment is carried out, so that the detection of a hot plug is judged only based on the fact that whether the SIM card exists or not, rather than be judged based on a card support of the SIM card, erroneous judgment due to the empty card support of the SIM card can be avoided, and the detection precision of the hot plug is improved.
Description
Technical field
The present invention relates to the portable terminal development technique, relate in particular to a kind of hot plug detection method, device, and portable terminal.
Background technology
Subscriber identification module (Subscriber Identification Module, SIM) card is a kind of integrated circuit (Integrated Circuit that has, IC) smart card of chip, be used to be installed in and carry out user identity in the portable terminal and differentiate, and recording user basic document, address list, communication information etc.Along with developing rapidly and extensive use of mobile communication technology, at present a lot of mobile subscribers hold multiple SIM card, so that dissimilar contact persons is used different SIM card, perhaps use different SIM card in different areas, the realization multiple SIM card is replaced use on same portable terminal.
At present, a lot of portable terminals generally are not supported in and directly plug SIM card under the electric power thus supplied, it is the hot plug function of SIM card, for fear of directly plug SIM card and consequence such as cause that SIM card burns out under the portable terminal power supply state, be used to install the bottom that is arranged on the battery installation position with the SIM card slot of reading SIM card data usually, therefore, when the user changes SIM card in the portable terminal, need shut down, retract battery, take out former card, a series of flow processs of neocaine being installed and starting shooting again, operating process is loaded down with trivial details and lose time, for user's use has caused inconvenience.
In order to solve SIM card hot plug problem, assurance is stuck in the plug process safe, the hot plug sense switch need be set on portable terminal, under power supply state, detect when plugging SIM card, take corresponding safety operation, prevent to burn out SIM card, at present, detection how to carry out the SIM card hot plug is a problem demanding prompt solution.
A kind of scheme that addresses this problem is by detecting whether there is the SIM card Kato, to judge whether to have carried out the SIM card hot plug.
The drawback of this method is, when having empty SIM card Kato, the erroneous judgement of hot plug can occur, and the detection of hot plug is not accurate enough, can influence the normal use of portable terminal.
In sum, at present, the method accuracy of carrying out the hot plug detection is lower.
Summary of the invention
The embodiment of the invention provides a kind of hot plug detection method, device and portable terminal, to improve the accuracy that hot plug detects.
A kind of hot plug checkout gear comprises:
The hot plug sense switch is used for opening when there is SIM card in sim card connector, otherwise cuts out; Perhaps when having SIM card in the sim card connector, close, otherwise open;
Detecting unit is used for closing by opening to become when the hot plug sense switch, perhaps becomes when opening by closing, and determines to exist hot plug, and carries out hot plug and handle.
A kind of portable terminal comprises the hot plug checkout gear that the embodiment of the invention provides.
A kind of hot plug detection method is characterized in that, comprising:
Determine that the hot plug sense switch cuts out by opening to become, perhaps open, open when there is the User Recognition SIM card in described hot plug sense switch in sim card connector, otherwise close by closing to become, close when perhaps in sim card connector, having SIM card, otherwise open;
