First embodiment
Fig. 3 is a flowchart illustrating a method for selecting a multi-region SIM card according to an embodiment of the present invention. Referring to fig. 3, the method includes:
step S110: the server obtains a selection request sent by the user terminal, wherein the selection request comprises network information.
When the user is out of the country, the service SIM card of the user terminal needs to be replaced so that the local SIM card can be used as the service SIM card.
In the embodiment of the present invention, the user terminal may send a selection request including the network information to the server. It is understood that the network information is network identification information of the local operator.
Further, a specific implementation manner of sending the selection request to the server by the user terminal may be that the user terminal is in communication connection with the server in the selection system of the SIM, and the user terminal sends the network identification information to the server. The specific network identification information may be location information. The communication connection between the user terminal and the server in the selection system of the SIM is realized, specifically, the user terminal is provided with a service SIM card capable of realizing global roaming, so that the communication connection between each position of the user terminal and the server can be realized. Therefore, the user terminal can send the network identification information of the position to the server in the selection system of the multi-region SIM card.
Of course, the specific implementation manner of the user terminal sending the selection request to the server is not limited in the embodiment of the present invention.
Correspondingly, the server receives a selection request including network information sent by the user terminal. Then, the server can send a selection request including the network information to an industrial personal computer in communication connection with the server.
Step S120: and the industrial personal computer selects the SIM card corresponding to the network information from the SIM card pool according to the selection request.
After receiving a selection request including network information, the industrial personal computer can select an SIM card corresponding to the network information from the SIM card pool according to the selection request. The SIM card pool is formed by a plurality of SIM cards coupled on a singlechip coupled with the industrial personal computer. The multiple SIM cards may be SIM cards served by operators in different regions, that is, different SIM cards have different network information. For example, the plurality of SIM cards are those of operator servers in the united states, japan, germany, hong kong, taiwan, uk, and the like. The specific region corresponding to the SIM card is not limited in the embodiment of the present invention.
Of course, the multiple SIM cards in the SIM card pool should be usable, i.e. registered SIM cards. Therefore, before step S120, the method may further include: the industrial personal computer sends SIM card reading instructions to the plurality of second single-chip computers through the plurality of first single-chip computers; the second single-chip microcomputers read the information of the SIM cards according to the SIM card reading instruction and send the information to the industrial personal computer through the first single-chip microcomputers; and the industrial personal computer registers the information of the plurality of SIM cards and acquires the registration information of the plurality of SIM cards.
The industrial personal computer obtains the information of the multiple SIM cards through the first single chip microcomputer and the second single chip microcomputer, registers the information of the multiple SIM cards, and stores the successfully registered information, so that the information can be quickly searched when the SIM card pool is used. In addition, the industrial personal computer stores all information of a plurality of SIM cards.
After acquiring the registration information of the multiple SIM cards, the method for selecting the multiple SIM cards may further include: and the industrial personal computer stores the registration information of the plurality of SIM cards according to a hash list.
The hash list is a data structure directly accessed according to the key value. That is, the registration information is mapped to a position in the table to access the record, so that the searching speed is increased. Of course, the storage manner of the registration information of the SIM card is not limited in the embodiment of the present invention.
The industrial personal computer can directly select the SIM card according to the network information when selecting the SIM card according to the selection request including the network information. For example, if the network information is network identification information formed by location information, a SIM card may be selected according to the location information, and the region to which the operator corresponding to the selected SIM card belongs should correspond to the location information.
Step S130: and the industrial personal computer takes the SIM card corresponding to the network information as a current service SIM card of the user terminal.
After the industrial personal computer selects the SIM card corresponding to the network information, the SIM card corresponding to the network information can be used as the current server SIM card of the user terminal sending the selection request.
Of course, after the SIM card corresponding to the network information is used as the current server SIM card of the user terminal, the information of the SIM card corresponding to the network information should be sent to the user terminal, so that the user terminal can use the SIM card corresponding to the network information. Therefore, the method for selecting the multi-region SIM card may further include: the industrial personal computer sends the SIM card information of the SIM card corresponding to the network information to the user terminal through the server; and the user terminal receives the SIM card information and activates the SIM card corresponding to the network information according to the SIM card information.
Specifically, the industrial personal computer may send the SIM card information of the SIM card corresponding to the network information to a server in a system for selecting the SIM card in the multi-region, and then the server sends the SIM card information to the user terminal that sends the selection request.
In the embodiment of the invention, the industrial personal computer can adopt an aes encryption algorithm in transmitting information to the server, rsa signature algorithm can be adopted in authenticating the server, and a crc algorithm can be adopted in serial port verification. Of course, the encryption algorithm, the verification algorithm and the serial port test algorithm for data transmission by the industrial personal computer are not specifically limited in the embodiment of the present invention.
Of course, the industrial personal computer should also acquire the SIM card information of the SIM card before sending the SIM card information of the SIM card corresponding to the network information to the server. The industrial personal computer can adopt a 'getseverinfo' instruction to acquire the SIM card information. The industrial personal computer may select the SIM card according to the network information, and then send a reading instruction to the first single chip microcomputer according to an identifier of the SIM card, such as a card number, the first single chip microcomputer sends the reading instruction to the second single chip microcomputer, and the second single chip microcomputer feeds back the SIM card information of the SIM card corresponding to the reading instruction to the industrial personal computer through the first single chip microcomputer.
After obtaining the SIM card information of the SIM card, the user terminal may activate according to the SIM card information, so that the user terminal can use the SIM card for communication. Specifically, activating the SIM card corresponding to the network information according to the SIM card information may include: the user terminal stores the SIM card information into a virtual SIM card; the user terminal authenticates the virtual SIM card to obtain an authentication result; and if the authentication result is that the authentication is successful, the user terminal determines that the SIM card corresponding to the network information is successfully activated.
The user terminal can realize the virtual SIM card technology, the SIM information is stored in the virtual SIM card, then the authentication operation is carried out on the virtual SIM card, and if the authentication is successful, the SIM card is successfully activated. After the user terminal successfully activates the SIM card corresponding to the network information, the user terminal completes the replacement of the current service SIM card of the user terminal, so that the user terminal can perform network communication and the like by using the SIM card corresponding to the network information.
In the embodiment of the present invention, the method for selecting a multi-region SIM card may further include: the industrial personal computer sends a heartbeat instruction to the server according to preset interval time; and when the state corresponding to the heartbeat instruction is a communication disconnection state, the server acquires a selection request sent by the user terminal so that the user terminal completes the selection of the service SIM card again.
After the user terminal completes replacement of the current service SIM card, the situation that a plurality of SIM cards coupled with the industrial personal computer are disconnected may occur, so that real-time detection on the communication condition is required. The industrial personal computer and the server can be in a tcp communication mode, a tcp thread adopts a poll io multiplexing model to read and write messages, and a heartbeat instruction is sent to the server at regular time. When the state corresponding to the heartbeat instruction is a communication disconnection state, namely, when no heartbeat exists, the socket pipeline can be disconnected. Then, the server may send a selection instruction acquisition request to the user terminal. Correspondingly, the user terminal feeds back a selection request to the server, wherein the selection request can include network information, then the contents of the steps S120 to S130 are repeated, and the industrial personal computer sends the SIM card information of the SIM card corresponding to the network information to the user terminal through the server, until the user terminal receives the SIM card information, and completes the replacement of the current service SIM card by the user terminal again according to the step that the SIM card corresponding to the network information is activated by the SIM card information.
