Detailed Description
In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings.
The invention realizes that the same card slot can be compatible with the functions of the SIM card and the IC card simultaneously by identifying and supporting the SIM card and the IC card in one card slot, thereby effectively improving the use efficiency of the card slot in the equipment and bringing greater convenience for the use of the card of the electronic equipment in work and life of people.
As shown in fig. 1, is a typical form of the main file system partition of the SIM card. Both SIM cards and IC cards are required to meet the basic ISO7816 protocol, and they differ mainly in the file system present therein.
The invention realizes the automatic identification of the SIM card and the IC card in the same card slot by different acquisition modes of the SIM card and the IC file system. The following is a detailed description of the preferred embodiments of the present invention:
referring to fig. 2, a method for adapting a SIM card and an IC card according to the present invention in a preferred embodiment includes:
s101, arranging a self-adaptive card slot for inserting an SIM card or an IC card on equipment;
s102, starting a device power supply, and electrifying the self-adaptive card slot;
step S103, judging whether a reset response ATR signal is acquired or not,
if the reset response ATR signal cannot be acquired, returning a card not inserted or invalid card signal, and powering off the adaptive card slot;
if the reset response ATR signal is obtained, returning a card-inserted signal;
s104, judging whether a DF file system is acquired or not after receiving the card inserting signal,
if the DF file system is obtained, returning an SIM card insertion confirmation signal; activating the SIM card and registering the network, and then performing APDU interaction;
if the DF file system is not obtained, returning an IC card insertion confirmation signal; keeping the power-on state of the IC card and waiting for APDU interaction of the user.
As shown in the figure, the present invention firstly needs to configure an adaptive card slot capable of inserting a SIM card or an IC on a device, and the connection terminal in the card slot can simultaneously adapt to the configuration position of each connection terminal of the SIM card and the IC card, so as to implement power-on and data transmission. After the power supply is started, the self-adaptive card slot can perform power-on operation on the inserted card; of course, the voltage for powering up needs to be set according to actual conditions, and includes voltage values such as 1.8V, 3.0V and 5V. The purpose of automatic power-on can be realized by different setting voltages on the continuous turns. Of course, when the power-on voltage is accurate, the relevant response signal is acquired, then the power-on voltage does not change any more, and the communication with the card is determined according to the voltage.
After the power is on, whether a SIM card or an IC card is inserted is judged by checking whether an ATR signal of a reset response is obtained or not, if the ATR signal is not obtained, the SIM card or the IC card is not inserted or an invalid card is inserted, and at the moment, the adaptive card slot is controlled to perform power-off operation on the SIM card or the IC card.
And when the ATR signal is obtained by checking, the inserted card is indicated to be a valid card, namely a SIM card or an IC card, and then the judgment stage of the SIM card and the IC card is started. Because the file systems of the SIM card and the IC card are different, after the ATR signal is obtained, whether a DF file system (such as one of the SIM card file systems shown in FIG. 1) can be obtained is further checked, the SIM card file system necessarily comprises the DF file system, and therefore, if the DF file system data can be obtained, the inserted card can be the SIM card by default; and if the DF file system cannot be acquired, the inserted card is the IC card by default.
After the card is determined to be the SIM card, activation or network registration operation may be started, and subsequently APDU interactive communication of the SIM card is performed. And when the card is determined to be the IC card, the power-on state of the IC card is maintained according to preset or self-adaptive parameters, and the start of APDU interaction of the IC card is waited.
Therefore, by the SIM card and IC card self-adapting method, the SIM card or the IC card can be automatically identified no matter the SIM card or the IC card is inserted into the same self-adapting card slot, and after the identification is finished, the electrification and communication of the card slot can be controlled according to different data reading modes of the SIM card or the IC card, so that the effect that the SIM card and the IC card are compatible in the same card slot is realized.
Furthermore, the invention also comprises an APDU interactive reporting mode for setting the SIM card and the IC card, after the returned 61XX or 6CXX status words are obtained through APDU interaction, the system framework layer can be selected to obtain the subsequent instructions and data by setting the reporting mode, and then the application program can obtain the instructions and data from the system framework layer; or choose to have the application actively fetch instructions and data directly.
In the foregoing method for adapting a SIM card and an IC card according to the present invention, in a preferred embodiment, after obtaining the DF file system, the method further includes determining whether one or a combination of the ICCID, the IMSI, and the PL file system is obtained;
if one or the combination of the ICCID, the IMSI and the PL file system is obtained, returning an SIM card insertion confirmation signal; executing the SIM card activation and network registration;
if the ICCID, the IMSI and/or the PL file system cannot be obtained, returning an IC card insertion confirmation signal; keeping the power-on state of the IC card and waiting for APDU interaction of the user.
The DF file system of the SIM card comprises an ICCID file system, an IMSI file system and a PL file system, so that the accuracy of the inserted card as the SIM card is further confirmed by confirming whether the file system can be acquired or not. If the further acquired file system is one or a combination of the ICCID, the IMSI and the PL file systems, the card is considered as the SIM card, and then subsequent communication operations such as SIM card activation, registration and the like are carried out.

When the power supply of the equipment is started to power on the self-adaptive card slot, a starting interface of an application user interface is displayed on the display screen, for example, the main interface of the application user interface is started; when the process of electrifying the card in the self-adaptive card slot in the step two is carried out, a return signal of the SIM card and the like are obtained, and a graphical indication of the obtained signal after electrification appears in an application user interface; and in the third step and the fourth step, according to the judgment result, displaying an icon that the card in the self-adaptive card slot is the SIM card or the IC card on the application user interface. Through the arrangement of the signal output module, the output display of the application user interface is better, and a more intuitive identification process of the self-adaptive card slot and the monitoring of the card state can be brought to a user.

And Di is a bit rate adjustment factor (bit rate adjustment factor), and the calculation formula is F × Di/Fi.
The Baud rate value during the IC card identification can be obtained by calculating Fi and Di returned by the IC card, and the Baud rate matched with the IC card is set in a signal clock for reading the IC card, so that the self-adaptive identification and support of the IC card are realized; of course, when different IC cards are used, the situation that the IC cards cannot be identified due to different baud rates can be met, and the purpose that different IC cards can be identified is achieved by setting the card slot to read the baud rate of the IC cards through the method and the device.
In the foregoing SIM card and IC card adaptive method according to the present invention, in the preferred embodiment of the present invention, in step four, the IC card power-on state is maintained, after the APDU interaction of the user is waited, the time-out time of the APDU interaction is set, and when the APDU interaction does not obtain the return information within the time-out time of the APDU interaction, a card unplugged signal or an invalid IC card signal is returned, and the adaptive card slot is powered off.
