[0031] Please combine Figure 1 The present application provides a wearable device 10, which is wirelessly connected to a mobile terminal 20. The wearable device 10 is provided with a SIM card, a first processor 12 and a first communication module 14. The mobile terminal 20 includes a second radio frequency module 22. The first processor 12 is used to: when a wireless connection is established between the mobile terminal 20 and the wearable device 10, read and copy the SIM card data of the SIM card, control the first communication module 14 to send the SIM card data to the mobile terminal 20 so that the mobile terminal 20 controls the second radio frequency module 22 to communicate with the base station according to the SIM card data.

[0032] The wearable device 10 of the present application is provided with a SIM card. When the mobile terminal 20 is wirelessly connected to the wearable device 10, the SIM card data of the SIM card is transmitted to the mobile terminal 20, so that the mobile terminal 20 communicates with the base station according to the SIM card data through the second radio frequency module 22. Thus, the mobile terminal 20 can indirectly connect to the base station through the mobile terminal 20 to achieve cellular network communication, thereby avoiding the wearable device 10 from being in a continuous standby state due to the SIM card being stationed on the network, which causes the wearable device 10 to consume a large amount of power. In this way, the battery life of the wearable device 10 is extended, and the user experience is improved.

[0033] It should be noted that the wearable device 10 may be a smart wearable device such as a smart watch, a smart bracelet, a smart helmet, smart glasses, a virtual reality device, or an augmented reality device, etc. For example, in the present application, the wearable device 10 may be a smart watch.

[0034] The wearable device 10 includes at least one SIM card slot 16, a first communication module 14, and a first processor 12, wherein the first processor 12 is connected to the SIM card slot 16 and the first communication module 14. The SIM card slot 16 is inserted with a SIM card, and the number of SIM cards can be one or more.

[0035] The SIM card includes corresponding SIM card data, which may include but is not limited to a unique identification code (ICCID), an International Mobile Subscriber Identification Number (IMSI), a Service Provider Name (SPN), a Temporary Mobile Subscriber Identity (TMSI), Forbidden PLMNs (FPLMNs), Administrative Data (AD), Emergency Call Codes (ECC), Mobile Station International ISDN Number (MSISDN), Short Message Service (SMS), a Phone Book, a Personal Identification Number (PIN), etc. After the user installs the SIM card in the SIM card slot 16, the first processor 12 reads the IMSI and TMSI information from the SIM card through the SIM card slot 16.

[0036] The first processor 12 can refer to the ISO7816 communication protocol to read and write the SIM card data of the SIM card in APDU format. And the SIM card data in APDU format, wherein the APDU request packet format is:

[0037] CLA INS PI P2 P3 DATA1

[0038] Among them, CLA is the command category, which is always A0 in GSM applications. INS is the command code, which varies depending on the command. P1 and P2 are command parameters, which vary depending on the command. P3 is the data length, which indicates the number of data characters transmitted during the command (it can be the length of data input from the ME to the SIM, DATA1, or the length of data returned from the SIM to the ME, DATA2). When data is sent from the SIM card, P2 = 00 means the data length is 256 characters. When data is sent from the ME, P3 = 00 means no data is transmitted.

[0039] The APDU response packet format is:

[0040] DATA2 SW1 SW2

[0041] SW1 and SW2 are status words, indicating whether the command was successfully executed. SW1 = 90, SW2 = 00 indicates that the command was successfully completed. SW1 = 91, SW2 = XX indicates that the SIM card is about to transmit the command to the ME. SW1 = 9F, SW2 = XX indicates that there is a response data of XX length. SW1 = 94, SW2 = 04 indicates that the file cannot be found or the parameters are incorrect. SW1 = 6D, SW2 = 00 indicates an unknown command.

[0042] The first communication module 14 may include a wireless communication module such as a Bluetooth module, a Wi-Fi module, etc., for realizing a wireless connection such as Bluetooth or Wi-Fi with the mobile terminal 20 to realize wireless communication between the wearable device 10 and the mobile terminal 20 .

[0043] Furthermore, when the first processor 12 detects that the first communication module 14 is communicating with the mobile terminal 20, the SIM card data can be read from the SIM card in the SIM card slot in the APDU format and sent to the first communication module 14. Alternatively, when the first processor 12 obtains that the first communication module 14 has received a communication request from the mobile terminal 20, the SIM card data can be read from the SIM card in the APDU format and sent to the first communication module 14. For example, the first communication module 14 has a time limit or a usage limit for sending SIM card data. When the mobile terminal 20 needs to make a call again, the mobile terminal 20 needs to send a communication request to obtain the SIM card data. Therefore, when the first processor 12 detects that the first communication module 14 has received a communication request, the SIM card data can be read from the SIM card in the APDU format and sent to the first communication module 14. It should be noted that the communication request can be triggered by the user making a call through the mobile terminal 20.

[0044] After receiving the SIM card data in the APDU format, the first communication module 14 may encapsulate the SIM card data in the APDU format into a TCP / UDP packet and send the packet to the mobile terminal 20 .

[0045] After receiving the SIM card data encapsulated in TCP / UDP, the mobile terminal 20 can parse the TCP / UDP SIM card data into APDU format SIM card data. Thus, the mobile terminal 20 can control the radio frequency module to connect to the base station according to the SIM card data, realize the communication between the home network and the mobile cellular network, and enable the wearable device 10 to indirectly realize communication services such as making or receiving calls through the mobile terminal 20. In addition, since the radio frequency module realizes communication with the base station according to the SIM card data in the mobile terminal 20, the wearable device 10 can turn off the standby mode of the SIM card, which reduces the power consumption of the wearable device 10. In addition, since the wearable device 10 is not directly connected to the base station to realize the communication between the home network and the mobile cellular network, the wearable device 10 does not need to set up a radio frequency module to realize the mobile cellular network communication. This can not only further reduce the power consumption of the wearable device 10 and extend the battery life of the wearable device 10, but also reduce the size of the wearable device 10 and save the cost of the wearable device 10.

[0046] Please combine Figure 2 In some embodiments, the wearable device 10 further includes a first radio frequency module 18, and the first processor 12 is further configured to control the first radio frequency module 18 to communicate with the base station according to the SIM card data.

[0047] It can be understood that since the wearable device 10 mentioned above needs to be wirelessly connected to the mobile terminal 20 to achieve the network station to make or receive calls, and if the mobile terminal 20 and the wearable device 10 are too far away and cannot be connected wirelessly through Bluetooth or Wi-Fi, the wearable device 10 cannot make or receive calls. Therefore, in this embodiment, the wearable device 10 can also be provided with a first radio frequency module 18, and the first radio frequency module 18 can be directly connected to the base station according to the SIM card data of the SIM card to achieve the network station function.

[0048] Specifically, the wearable device 10 may also include a SIM card driver module 19, which is connected to the SIM card slot 16. The first RF module 18 is connected to the first processor 12. The first RF module 18 may include a first RF driver unit 182 and a first RF device 184. If the first processor 12 detects that the first communication module 14 is disconnected from the mobile phone, the first processor 12 may control the SIM card driver unit 19 to drive the SIM card to read the SIM card data, and control the first RF driver unit 182 to drive the first RF device 184 to connect to the base station according to the SIM card data, so as to realize the network and communication functions of the wearable device 10. In this way, the wearable device 10 can make or receive calls even when the wireless communication with the mobile terminal 20 is disconnected.

[0049] Please further combine Figure 1The present application also provides a mobile terminal 20, which can be an electronic device with wireless communication and mobile communication functions, such as a mobile phone or a tablet. The mobile terminal 20 is wirelessly connected to the wearable device 10.

[0050] The mobile terminal 20 includes a second communication module 26, a second processor 24 and a second radio frequency module 22, wherein the second processor 24 is used to control the second communication module 26 to obtain the SIM card data of the SIM card in the wearable device 10 when the mobile terminal 20 and the wearable device 10 establish a wireless connection. The second processor 24 is also used to store the SIM card data and control the second radio frequency module 22 to communicate with the base station according to the SIM card data.

[0051] Specifically, the second communication module 26 can communicate with the wearable device 10 via Bluetooth or Wi-Fi. For example, the second communication module 26 includes a Bluetooth module, and the second communication module 26 realizes a Bluetooth connection with the wearable device 10 through the Bluetooth module. For another example, the second communication module 26 includes a Wi-Fi module, and the second communication module 26 realizes a Wi-Fi connection with the wearable device 10 through the Wi-Fi module.

[0052] Furthermore, when the second processor 24 detects that the second communication module 26 is connected to the wearable device 10, the second processor 24 can directly control the second communication module 26 to receive the SIM card data encapsulated in a TCP / UDP packet from the wearable device 10 and parse it into SIM card data in APDU format. Alternatively, after the second processor 24 controls the second communication module 26 to send a communication request to the wearable device 10, the second processor 24 can control the second communication module 26 to receive the SIM card data encapsulated in a TCP / UDP packet from the wearable device 10 and parse it into SIM card data in APDU format. Furthermore, the second processor 24 can store the SIM card data in APDU format and control the second RF module 22 to communicate with the base station based on the SIM card data, thereby enabling the mobile terminal 20 to communicate with the mobile cellular network.

[0053] Please combine Figure 3 In some embodiments, the second processor 24 includes a call driving unit 242 and a telephone unit 244. The telephone unit 244 is used to store SIM card data. The call driving unit 242 is used to control the second communication module 26 to initiate a communication request to the wearable device 10, obtain the response request generated by the wearable device 10 receiving the communication request and reading and copying the SIM card data of the SIM card according to the communication request, and parse the response request to obtain the SIM card data.

[0054] In some embodiments, the second RF module 22 includes a second RF driving unit 222 and a second RF device 224 . The second RF driving unit 222 is configured to drive the second RF device 224 to transmit RF signals to communicate with the base station.

[0055] Specifically, after the second processor 24 receives the SIM card data, the second processor 24 can control the second RF driver unit 222 to drive the second RF device 224 to transmit RF signals based on the SIM card data to connect to the base station. After the second RF device 224 successfully connects to the base station, the mobile terminal 20 can achieve network access and communication functions. In this way, the mobile terminal 20 can achieve communication functions such as making or receiving calls.

[0056] Please combine Figure 4 The present application also provides a communication method for the wearable device 10 described above, wherein the wearable device 10 is wirelessly connected to the mobile terminal 20 described above, and the communication method includes:

[0057] S12, when the mobile terminal and the wearable device establish a wireless connection, receiving a communication request from the mobile terminal to read and copy SIM card data of the SIM card; and

[0058] S14, sending the SIM card data to the mobile terminal to control the second radio frequency module to connect to the base station according to the SIM card data to achieve mobile communication.

[0059] In this way, the wearable device 10 can achieve mobile cellular network communication without setting up a radio frequency module, which can not only further reduce the power consumption of the wearable device 10 and extend the battery life of the wearable device 10, but also reduce the volume of the wearable device 10 and save the cost of the wearable device 10.

[0060] Please combine Figure 5 The present application also provides a communication method for the mobile terminal 20 described above, wherein the mobile terminal 20 is wirelessly connected to the wearable device 10 described above, and the communication method includes:

[0062] S24, storing the SIM card data and controlling the second radio frequency module to communicate with the base station according to the SIM card data.

[0063] In this way, when the mobile terminal 20 communicates with the wearable device 10, it can connect to the base station without inserting a SIM card to achieve communication functions such as receiving or making calls.
