In addition, the first change-over switch is connected with the communication storage device through a first communication storage interface of the communication device, and the second change-over switch is connected with the communication device through a second communication storage interface of the communication storage device.
As can be seen from the connection relationship described above: the first UICC module and the second UICC module can be connected through the switching action of the first switch and the second switch, so that the user identification function of the terminal equipment is realized; or, the first storage module and the second storage module can be connected through the switching action of the first switch and the second switch, so that the storage function of the terminal device is realized.

It should be noted that, in the embodiment of the present application, the type of the two-wire bus and the type of the first communication storage interface for connecting the first storage module and the second storage module are not limited, that is, the first storage module and the second storage module do not necessarily adopt USB connection, and the first communication storage interface is not limited to a USB interface. The first storage module and the second storage module are connected by adopting other types of two-wire buses, and the first communication storage interface is a two-wire interface of other types, so that the scheme of the embodiment of the application can be realized.

The communication storage device can be used for realizing the function of identifying the kinetic energy by the user and can also be used for realizing the storage function. Which function the communication storage device specifically implements can be switched by the second switch in the communication storage device.
In particular, the communication storage device may have the same shape and size as the SIM card, micro SIM card or nano SIM card.

The communication device 200 comprises a first UICC module 201, a first memory module 202, a first switch 203, and a first communication memory interface 204. Wherein,
the first switch 203 is used for connecting the first communication storage interface 204; the first switch 203 is further configured to connect the first UICC module 201 or the first storage module 202, so that the first communication storage interface 204 is connected with the first UICC module 201, or so that the first communication storage interface 204 is connected with the first storage module 202; the first communication storage interface 204 is used for connecting the communication storage device 300; when the first communication storage interface 204 is connected with the first UICC module 201, the communication apparatus communicates with the communication storage apparatus 300 through the first communication storage interface 204 to implement the user identification function; when the first communication storage interface 204 is connected to the first storage module 202, the communication device communicates with the communication storage device 300 through the first communication storage interface 204, so as to implement a storage function.
It should be noted that the communication device 200 can communicate with the communication storage device through the first communication storage interface 204. Illustratively, the communication device 200 can be connected to the communication storage device through a two-wire bus, which can be USB, for example, in which case the first communication storage interface 204 is a USB interface. Of course, the type of the two-wire bus connecting the communication device 200 and the communication storage device and the type of the first communication storage interface 204 in the embodiment of the present application are not limited, that is, the USB connection is not necessarily adopted between the communication device 200 and the communication storage device, and the first communication storage interface 204 is not limited to the USB interface.
In the embodiment of the present application, the communication apparatus 200 may be understood as follows: communication apparatus 200 may be understood as a chip integrated circuit, such as a System On Chip (SOC) chip, a Central Processing Unit (CPU), an arm (advanced RISC machine) processor, a Field Programmable Gate Array (FPGA), a special purpose processor, and other devices with computing processing capabilities; the communication device 200 can also be understood as a terminal device, and the communication device 200 cooperates with the communication storage device to realize the user identification function and the storage function of the terminal device.
Specifically, when the first communication storage interface 204 is connected to the first UICC module 201, the first communication storage interface 204 may be used to transmit a data signal and a clock signal, and at this time, the communication device 200 and the communication storage device cooperate with each other to implement a user identification function of the terminal device; when the first communication storage interface 204 is connected to the first storage module 202, the first communication storage interface 204 can be used to transmit two paths of data signals, and at this time, the communication device 200 and the communication storage device are mutually matched to realize the storage function of the terminal device.
By adopting the implementation mode, the storage function and the user identification function can be realized by time division multiplexing of two pins originally used for transmitting the clock signal and the data signal in the communication device.
In addition, in the embodiment of the present application, when the communication apparatus 200 is powered on, the first switch 203 may be connected to the first UICC module 201.
In the embodiment of the present application, when the communication apparatus 200 is powered on, the first switch 203 may be connected to the first UICC module 201, and its specific meaning is: when the communication apparatus 200 is powered on, the terminal device where the communication apparatus 200 is located can communicate with other terminal devices. For example, the communication device 200 is arranged in a mobile phone, and when the communication device 200 is powered on (for example, when the mobile phone is powered on), the mobile phone is preferentially ensured to realize the user identification function, so that the mobile phone can acquire the service provided by an operator in as short a time as possible, realize communication with other equipment, and meet the requirement of a user for communication by using the mobile phone.
With the communication apparatus 200 provided in the embodiment of the present application, since the first switch 203 in the communication apparatus 200 can switch between the first UICC module 201 and the first storage module 202, and the first switch 203 is connected to the communication storage apparatus through the first communication storage interface 204. Therefore, with the communication device 200 according to the embodiment of the present application, by switching the first switch 203, the communication device 200 can communicate with the communication storage device through the first communication storage interface 204 to realize the user identification function, and the communication device 200 can communicate with the communication storage device through the first communication storage interface 204 to realize the storage function. Therefore, with the communication device 200 provided in this embodiment of the present application, the external storage function and the user identification function of the terminal device can be realized when the terminal device where the communication device 200 is located is removed from the SD card and the SD card socket, so that the purpose of saving the space of the terminal device is achieved without affecting the function of the terminal device.
Based on the above embodiments, the embodiments of the present application further provide a communication storage device. Referring to fig. 3, the communication storage 300 includes a second UICC module 301, a second storage module 302, a second switch 303, and a second communication storage interface 304. Wherein,
the second switch 303 is used for connecting the second communication storage interface 304; the second switch 303 is further configured to connect the second UICC module 301 or the second storage module 302, so that the second communication storage interface 304 is connected to the second UICC module 301, or so that the second communication storage interface 304 is connected to the second storage module 302; the second communication storage interface 304 is used for connecting the communication device 200; when the second communication storage interface 304 is connected with the second UICC module 301, the communication storage apparatus 300 communicates with the communication apparatus 200 through the second communication storage interface 304 to implement the user identification function; when the second communication memory interface 304 is connected to the second memory module 302, the communication memory device 300 communicates with the communication device 200 through the second communication memory interface 304 to implement a memory function.
It should be understood that the communication storage device 300 can be used to implement both user identification capabilities and storage functions. Which function is specifically implemented by the communication storage apparatus 300 can be switched by the second changeover switch 303 in the communication storage apparatus 300. The communication storage device 300 can be understood as a device independent from the terminal equipment, and is used for cooperating with the communication device 200 in the terminal equipment to realize the user identification function and the storage function of the terminal equipment.
Specifically, when the second communication memory interface 304 is connected to the second UICC module 301, the second communication memory interface 304 is configured to transmit a data signal and a clock signal; when the second communication memory interface 304 is connected to the second memory module 302, the second communication memory interface 304 is used for transmitting two paths of data signals.
With this implementation, the memory function and the user identification function can be implemented by time-division multiplexing of the two pins originally used for transmitting the clock signal and the data signal in the communication memory device 300.
Further, when the communication apparatus 200 is powered on, the second changeover switch 303 connects the second UICC module 301.
As mentioned above, the communication apparatus 200 may be understood as a chip integrated circuit in a terminal device or as a terminal device. With the above scheme, when the communication apparatus 200 is powered on, the second switch 303 is connected to the second UICC module 301, and the specific meaning is: when the communication apparatus 200 is powered on, the communication apparatus 200 or a terminal device in which the communication apparatus 200 is located preferentially implements the user identification function. This has the advantage that it is ensured that the communication apparatus 200 or the terminal device in which the communication apparatus 200 is located can communicate with other terminal devices. For example, the communication device 200 and the external communication storage device 300 are configured in a mobile phone, and when the communication device 200 is powered on (e.g., when the mobile phone is powered on), the mobile phone is preferentially ensured to realize the user identification function, so that the mobile phone can acquire the service provided by an operator in as short a time as possible, realize communication with other devices, and meet the requirement of a user for communication by using the mobile phone.
Further, the communication storage apparatus 300 is the same in shape and size as the SIM card; or, the shape and size of the communication storage device 300 are the same as those of the micro SIM card; or the communication storage device 300 may have the same shape and size as the nano SIM card.
