Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Apparatus embodiment
According to an embodiment of the present invention, a SIM device for multi-network switching is provided, which specifically includes:
the multi-network switching module is used for switching networks, and the first SIM card holder is connected with the multi-network switching module and the terminal and used for placing the multi-network switching module, receiving signals sent by the multi-network switching module and sending the signals to the terminal.
The device still includes: and the second SIM card holder is connected with the multi-network switching module and used for placing the SIM card of the user.
The first SIM card seat is a flip type.
The first SIM card holder is self-ejecting.
On the basis of a flip-type or self-ejection SIM card seat, a 6P (or 7P) is connected into a three-in-one network circuit board: 6P is the number of terminals of the SIM card seat, which is a parameter of the specification;
fig. 1 is a detailed schematic diagram of a multi-network-switched SIM device according to an embodiment of the present invention, as shown in fig. 1:
finally, the circuit board and the SIM card seat are combined into a form of a circuit board with a multi-network switching MCU algorithm and a SIM card seat. Finally, the circuit board and the SIM card seat are combined into a form of a circuit board with a multi-network switching MCU algorithm and a SIM card seat.
The invention continues to use the technology of combining multiple networks into one, can automatically switch to other operator networks for network injection under the condition that a certain operator network has poor signal or no network coverage, and solves the problem that network injection cannot be performed due to network black holes formed by insufficient coverage of a single network signal.
Meanwhile, an SIM card seat can be opened for the user, so that the user can use the SIM card to participate in multi-network switching.
Patch cards of three operators are connected through an integrated circuit board, and a scheduling algorithm chip is added.
The algorithm chip is in butt joint with the upper layer communication module, and the mechanism of the communication instruction transparent transmission of the SIM card is realized.
And when the communication module carries out network injection, judging whether the current network is available according to the selected strategy.
And if the SIM card is not available, switching to another SIM card for network injection.
The MCU is connected with the MS-1, the MS-2 and the SIM card seat, the MCU realizes the instruction routing function, and in the process of network injection of the communication module, the MCU distributes instructions to the MS-1, the MS-2 or the SIM card inserted in the SIM card seat to execute according to the setting of the application layer.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; the technical solutions of the embodiments of the present invention are not modified or replaced, and the essence of the corresponding technical solutions does not depart from the scope of the present invention.
