[0064] When the smart card 60 is placed on the card tray 2 and the card tray 2 carrying the smart card 60 is inserted into the card socket 1, the smart card 60 is plugged into the card socket assembly 10, so that the interface 62 of the smart card 60 is connected to the interface 21 of the card socket 1, thereby enabling the smart card 60 to communicate with the processor 20.

[0065] Please also read Figure 5 The interface 21 may include a plurality of springs, which are used to be electrically connected to the data codec 22 to exchange a first data packet with the data codec 22, wherein the first data packet includes storage data and SIM data. Specifically, the interface 21 may include a first spring 211, a second spring 212, a third spring 213, a fourth spring 214, a fifth spring 215, a sixth spring 216, a seventh spring 217, and an eighth spring 218. The first spring 211 to the eighth spring 218 may all be electrically connected to the data codec 22 to exchange data packets with the data codec 22.

[0066] The first spring clip 211 is used to transmit the transmission data signal TX-, the second spring clip 212 is used to transmit the reference clock signal REF_CLK, the third spring clip 213 is used to transmit the reset signal RST, and the fourth spring clip 214 is used to transmit the transmission data signal TX+.

The seventh spring clip 217 is used to transmit the reception data signal RX-. The eighth spring clip 218 is used to transmit the reception data signal RX+.

[0067] Exemplarily, the eight spring pieces of the interface 21 are arranged into a first column of spring pieces and a second column of spring pieces along the length direction. The first column of spring pieces may include a first spring piece 211, a third spring piece 213, a fifth spring piece 215, and a seventh spring piece 217 arranged in the width direction.

[0068] When the smart card 60 is inserted into the card holder assembly 10, the first connection end 621, the second connection end 622, the third connection end 623, the fourth connection end 624, the fifth connection end 625, the sixth connection end 626, the seventh connection end 627 and the eighth connection end 628 of the interface 62 are respectively abutted and electrically connected with the first spring clip 211, the second spring clip 212, the third spring clip 213, the fourth spring clip 214, the fifth spring clip 215, the sixth spring clip 216, the seventh spring clip 217 and the eighth spring clip 218 of the interface 21 in a one-to-one correspondence.

[0069] For example, in an application scenario, the data codec 66 can receive storage data from the memory card circuit 64 and SIM data from the SIM card circuit 65, and encode the storage data transmitted by the memory card circuit 64 and the SIM data transmitted by the SIM card circuit 65 to generate multiple data packets, and can transmit the multiple data packets to the interface 21.

[0070] In a specific implementation process, the data codec 22 can receive data packets transmitted by the smart card 60 through the eight springs of the interface 21. It can be understood that in some embodiments of the present application, the data codec 22 can also decode multiple data packets transmitted by the eight springs of the interface 21 to obtain storage data and SIM data. The data codec 22 can transmit the storage data obtained after decoding to the application processor 23. The data codec 22 can also transmit the SIM data obtained after decoding to the modem 24.

[0071] Please refer to Figure 6 and Figure 7 The memory data transmitted by the memory card circuit 64 to the data codec 66 may include data packets DM1 and DM2. The SIM data transmitted by the SIM card circuit 65 to the data codec 66 may include data packets DS1, DS2, DS3 and DS4.

[0072] It can be understood that in the embodiment of the present application, the data codec 66 can receive the data packets DM1 and DM2 transmitted by the memory card circuit 64 and the data packets DS1, DS2, DS3 and DS4 transmitted by the SIM card circuit 65, and re-encode the received multiple data packets so that they can be packaged into Figure 7 The data packet shown.

[0073] like Figure 8As shown, data packet T1 may include data packet DM1 and data packet DS1, wherein data packet DM1 is memory data and data packet DS1 is SIM data. Data packet T2 may include data packet DM2 and data packet DS2, wherein data packet DM2 is memory data and data packet DS2 is SIM data.

[0074] For example, in the first time period, the data codec 66 transmits the data packet T1 to the interface 21 through the multiple connection ends of the interface 62, and the multiple springs of the interface 21 transmit the data packet T1 to the data codec 22, and the data codec 22 decodes the data packet T1 into the first memory data and the first SIM data. The first memory data is stored in the application processor 23, and the first SIM data is stored in the modem 24. In the second time period, the data codec 66 transmits the data packet T2 to the interface 21 through the multiple connection ends of the interface 62, and the multiple springs of the interface 21 transmit the data packet T2 to the data codec 22, and the data codec 22 decodes the data packet T2 into the second memory data and the second SIM data. The second memory data is stored in the application processor 23, and the second SIM data is stored in the modem 24.

[0075] In another application scenario, the data codec 22 can receive the storage data of the application processor 23 and the SIM data of the modem 24, and encode the storage data of the application processor 23 and the SIM data of the modem 24 to generate a data packet, and can transmit the data packet to the smart card 60.

[0076] In a specific implementation process, the data codec 22 can transmit the data packet to the interface 62 of the smart card 60 through the interface 21. The data codec 66 can receive the data packet transmitted by the interface 21 through the interface 62. It can be understood that in some embodiments of the present application, the data codec 66 can also decode the data packet transmitted by the interface 62 to obtain the storage data and the SIM data. Among them, the data codec 66 can store the storage data obtained after decoding in the storage card circuit 64. The data codec 22 can also store the SIM data obtained after decoding in the SIM card circuit 65.

[0077] By using the smart card and terminal device with SIM and SD storage functions of the present application, the storage card information and SIM information can be repackaged through a protocol and transmitted through the same interface, and then re-decoded on the smart card or terminal device. Based on such a design, the present application can not only realize the two-in-one of SIM card and memory card, but also reduce the number of IO of the smart card and improve the space utilization of the terminal device.

[0078] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application. Therefore, as long as they are within the scope of the essence and spirit of the present application, appropriate changes and modifications made to the above embodiments should fall within the scope of protection claimed in the present application.
