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(shuō)明書

The examples of the present disclosure provide a SIM card sharing method, which can be applied to a client (the client may include: a PAD and/or a mobile phone) that currently supports communication functions of a modem. If no SIM card is inserted into the client, or when a SIM card is inserted and the data traffic is limited, the terminal can share the SIM card of other servers through the SIM card sharing technology, i.e., “virtually moving the SIM card”, without plugging or unplugging any physical SIM card, so that the terminal can use the SIM card of another terminal to access the network and/or make calls.

As shown in FIG. 5, an example of the present disclosure provides a schematic diagram illustrating a framework of a client 410 and a server 310.

The server 310 includes two processors:

    • an application processor 311, used for information processing at the application layer; and
    • a modem processor 312, used for data processing of a modem.

The application processor 311 and the modem processor 312 exchange information through a multi-processor inter-process communication interface (or called as a general interface). The interface may be a Qualcomm Message Interface (QMI) as shown in FIG. 5. QMI is generally used for communication between chips produced by Qualcomm Inc.

The application processor 311 operates on the application layer, and the modem processor 312 can operate on the physical layer.
