Description
Technical field
The present invention relates to communication technical field, and in particular to a kind of film SIM card and its method for transparent data.
Background technology
Film SIM card technology refers to one film SIM card of attaching in the original SIM card of user (we are referred to as host's card),
And the SIM card attached has independent SIM card function and identity.Host blocks and the same SIM card in film card shared terminal
Groove, the STK menus provided by SIM card complete the handover operation between host's card and film card, so as to adjust and dispatch both
Between state of activation.
After insertion film card, film clamping pipe 7816 interfaces of end side, the order sent for terminal, after parsing
If order is to give film card, directly responded.If order is to give host's card, film card can be by blocking with host
Order is transmitted to host's card by 7816 interfaces, and the response of host's card also can return to terminal by film card.It is this to pass through film
The pattern ordered between card forwarding and response terminal and host's card, we are referred to as film card transparent data pattern.
Existing film card is all, by software Signal Transparent Transmission Technology, to easily cause compatibility issue, and SIM card fails to terminal response
Afterwards by reset, or switching on and shutting down again, or physics plugs SIM card, or switchgear offline mode to recover.
On the one hand these means cause very big influence to Consumer's Experience, on the other hand such as switchgear offline mode, and differing
Surely prove effective.
The content of the invention
(1) technical problem solved
In view of the shortcomings of the prior art, the present invention provides one kind and realizes that a hardware transparent data is cut in film SIM card
Function is changed, when terminal operation host's SIM card, hardware exchange is directly connected to the interface that terminal and host block, so as to improve end
The stability that end and host's cartoon are interrogated.
(2) technical scheme
To realize object above, the present invention is achieved by the following technical programs：A kind of film SIM card, including：Control
Device, the first interface being connected respectively with the controller two ends and second interface, it is characterised in that also include：Described first connects
On-off circuit, the controller connection switch electricity are connected between the output end of mouth and the output end of the second interface
Road, wherein, the first interface, the output end of second interface connect terminal, host's SIM card respectively；Terminal is sent out to film SIM card
Command signal is sent, the controller judges that the command signal should be responded by host's SIM card, then the controller sends control letter
Number so that the on-off circuit is closed, otherwise, the controller sends control signal so that the on-off circuit disconnects.
The first interface and second interface are the standard interfaces of ISO 7816.
A kind of method of film SIM card transparent data, it is characterised in that including：
Step S1, terminal send command signal to film SIM card, and the controller of the film SIM card is believed the order
Number judge, if the command signal should be handled by host's SIM card, step S2 is performed, if the command signal should be by institute
State film SIM card or handled by the film SIM card together with host's SIM card, then perform step S3；
On-off circuit closure in step S2, controller control film SIM card, so that host's SIM card and institute
Terminal communication is stated, the film SIM card enters listening mode；
Step S3, the controller control the on-off circuit to disconnect, and the film SIM card responds the command signal,
Or the film SIM card and host's SIM card respond the command signal, host's SIM card passes through the film SIM
Card sends response signal to the terminal.
(3) beneficial effect
The film SIM card of the present invention realizes the function of hardware transparent data switching, and when terminal operation host blocks, hardware is cut
Change and the interface of terminal and host's card is directly connected to, at this moment film card is in listening mode, when terminal operation film card, switching
General modfel is returned, the order of terminal is responded by film card is unified, so as to improve the stability of terminal and host's cartoon letters, lifting is used
Experience at family.
