摘要

The present disclosure relates to a SIM card sharing method and device, a communication device, and a storage medium. The SIM card sharing method applied to the first device may include: in response to the first device's requirement for obtaining cellular mobile communication, sending share request information to a second device through an interactive channel, where the interactive channel is established between the first device and the second device through a preset connection manner; receiving SIM card information that is returned by the second device based on the share request information; and establishing a cellular mobile communication connection with the base station according to the SIM card information.

說明書

The client sends a “SIM Ready” event to the Server App after completing the initialization of the Share-SIM card, and the server APP transfers this event to the Modem.

At this point, the server supports the client to complete the SIM card initialization through the established Bluetooth connection.

The Share-SIM card may access to the network by:

    • transferring, by the client, the authentication request issued by the network during accessing the network;
    • the authentication request being carried with AUTN and RAND;
    • transferring, by the Share-SIM server APK (i.e., the Server app), the authentication request to the Modem;
    • sending, by the Modem, the authentication request to the shared physical card to complete the authentication operation by the shared physical card and obtain the authentication result RES, and returning the RES to the Server app.

The Server app returns the authentication result to the client. At this point, the network registration is completed by the client under the cooperation of the server.

The de-energizing of the Share-SIM card may include operations described below.

The client sends the power down command “power down” to the server.

The Server app transfers the event to the Modem, and the Modem completes the de-energizing operation of the Share-SIM card, and sends ‘Power Down OK’ back to the Server app. The server sends the event back to the client to notify that the de-energizing is completed.
