Description

[0001] This application is a divisional application of the Chinese patent application with application number 201910579025.4, application date June 28, 2019, and invention name “User identity identification integrated card, data communication method, device, equipment and system”. Technical Field

[0004] In the IoT scenario that uses cellular networks for network connection, due to the complex cellular network standards of multiple network operators, the continuous evolution of the network, the continuous withdrawal of old 2G networks, and the incomplete coverage of new technology networks such as NB-IoT (Narrow Band Internet of Things), the coverage of operators in various regions is very uneven. In a large number of scenarios such as inside buildings, underground garages, and remote suburbs, only certain operator networks are available. If each site of an IoT application deployment uses a single operator network, there will be many single-operator blind spots. If each site performs signal evaluation and then deploys the best operator network according to the situation, the deployment labor cost will be greatly increased.

[0005] At the same time, the signal integrity rate index of single-operator base stations in China is generally only 99.75%. Coupled with the reasons such as the transmission optical fiber being dug up and the core network failing, the reliability of the single-operator cellular network at the same site will be even lower and cannot meet the high reliability requirements required by the Internet of Things applications.

[0006] Therefore, it is necessary to propose a data communication method that can effectively improve the stability and reliability of the communication connection of each IoT device in the IoT network. Summary of the invention

[0042] The data communication system of the present invention is used to enable data communication devices in the Internet of Things to be connected to other terminals in the Internet so that users can remotely control the data communication devices. Figure 1 , Figure 1 FIG. 1 is a schematic diagram of a data communication system according to an embodiment of the present invention. The data communication system 10 includes a data communication device 11 in the Internet of Things and a background server 12 communicating with the data communication device 11 .

The backend server 12 is used to bind the integrated circuit card identification codes of the plurality of subscriber identification cards in the data communication device 11 with the chip identification code of the control chip, so that the backend server 12 detects the data communication information of each subscriber identification card by detecting the data communication information of the control chip, and can perform data statistics and switching control on the subscriber identification card, so as to improve the stability of the communication signal of the data communication device 11 in the Internet of Things.

[0044] The SIM card here is a special smart card specified by major international standard organizations (such as GSM (a digital mobile communication standard formulated by the European Telecommunications Standards Institute (ETSI)) and 3GPP (3rd Generation Partnership Project)) and operators. Generally speaking, a SIM card includes an 8-bit CPU, 8KB of RAM (Random Access Memory) and 64-138KB of user storage; the core purpose of existing SIM cards is to store confidential authentication information of the operator network and IMSI (International Mobile Subscriber Identification Number) information such as mobile phone numbers; that is, for the communication module in the data communication device 11 to query the operator information, authentication information, mobile phone number and other information corresponding to the SIM card.

[0045] Please refer to Figure 2 , Figure 2 The data communication device in the data communication system of the present invention includes a user identity identification integrated card, and the user identity identification integrated card 20 includes a card body 21, a plurality of user identity identification cards 22, a control chip 23 and a communication interface 24.

[0046] The card body 21 includes a first circuit layout layer arranged on the front side of the card body and a second circuit layout layer arranged on the back side of the card body. The circuit layout layer here is used to form the routing between different pins or interfaces on the card body 21.

The user identification card 22 is connected to the communication interface 24 through the control chip 23.

[0048] The user identity integrated card 20 in this embodiment can be made into a 12mm*15mm Micro-SIM card or a 15mm*25mm standard SIM card.

[0049] Specifically, the control chip 23 may include a control ground pin CGND, a control power pin CVCC, a control reset pin CRST, a control clock pin CCLK, a plurality of identification card communication pins CIO1 and COI2, and an interface communication pin CIO.

[0050] The identification card communication pins CIO1 and COI2 should meet the GSM11.11VCC drive standard and domestic operator specification standards, and can independently drive different user identification cards to realize data reading and switching of user identification cards.

[0051] The control reset pin CRST should meet the GSM11.11RST signal interface standard and the requirements of domestic operators for the RST signal interface, and can sense and simulate the RST signal (reset signal) between the communication module of the data communication equipment and the user identity card.

[0052] The control clock pin CCLK should meet the GSM11.11CLK driving standard and the requirements of domestic operators for the CLK signal interface, and can sense and transparently transmit the CLK signal (clock signal) between the communication module of the data communication equipment and the user identity card.

[0053] The user identification card 22 includes an identification card ground pin GND, an identification card power pin VCC, an identification card reset pin RST, an identification card clock pin CLK, and a control communication pin I / O. The identification card ground pin GND is used to provide a ground voltage to the user identification card 22; the identification card power pin VCC is used to provide a driving voltage to the user identification card 22; the identification card reset pin RST is used to reset the user identification card 22; the identification card clock pin CLK is used to provide a clock signal for communication to the user identification card 22; the control communication pin I / O is connected to the identification card communication pins CIO1, COI2, and COI3 of the control chip 23 so that the control chip 23 drives the user identification card 22. The user identification card 22 in this embodiment can be a 5mm*6mm patch SIM card.

[0054] The communication interface 24 includes a power interface SIM_VDD, a reset interface SIM_RST, a clock interface SIM_CLK, a data interface SIM_DATA, and a ground interface SIM_GND.

[0055] Please refer to Figure 3 , Figure 3 The present invention is a schematic diagram of a specific circuit structure of an embodiment of a user identity recognition integrated card for data communication equipment of the present invention.

[0056] The control ground pin CGND of the control chip 23 and the identification card ground pin GND of the user identity card 22 are respectively connected to the ground interface SIM_GND; the control power pin CVCC of the control chip 23 and the identification card power pin VCC of the user identity card 22 are respectively connected to the power interface SIM_VDD; the control reset pin CRST of the control chip 23 and the identification card reset pin RST of the user identity card 22 are respectively connected to the reset interface SIM_RST; the control clock pin CCLK of the control chip 23 and the identification card clock pin CLK of the user identity card 22 are respectively connected to the clock interface SIM_CLK; the control communication pin CIO of the user identity card 22 is connected to the identification card communication pins CIO1 and COI2 corresponding to the control chip 23, and the interface communication pin CIO of the control chip 23 is connected to the communication interface 24.

[0057] Please refer to Figure 4a and Figure 4b , Figure 4a A front structural diagram of an embodiment of a user identity identification integrated card for data communication equipment of the present invention; Figure 4b The back structure diagram of an embodiment of the user identity identification integrated card of the data communication device of the present invention. The user identity identification integrated card in this embodiment includes three user identity identification cards 41 and a control chip 42. The three user identity identification cards 41 can be a mobile user identity identification card, a Unicom user identity identification card, and a Telecom user identity identification card.

[0058] In order to ensure the stability of the communication signal of the user identification card 41, the communication signal routing of the user identification card 41 and the communication signal routing of the control chip 42 are both realized through the first circuit layout layer (located on the front of the card body of the user identification integrated card). That is, the control communication pins I / O of the three user identification cards 41 are connected to the identification card communication pins CIO1, COI2, and COI3 corresponding to the control chip 42 through the routing of the first circuit layout layer; the interface communication pin CIO of the control chip 42 is connected to the data interface SIM_DATA through the routing of the first circuit layout layer.

[0059] Since the power signal and reset signal of the user identification card 41 are also used frequently, the relevant wiring is also set in the first circuit layout layer as much as possible. That is, the identification card power pins VCC of the three user identification cards 41 are set to a power collection point 411 through the wiring of the first circuit layout layer, and are connected to the power interface SIM_VCC through the power collection point 411, the wiring of the second circuit layout layer and the wiring of the first circuit layout layer; the control power pin CVCC of the control chip 42 is connected to the power interface SIM_VCC through the first circuit layout layer. The identification card reset pins RST of the three user identification cards 41 are set to a reset collection point 412 through the wiring of the first circuit layout layer, and are connected to the reset interface SIM_RST through the reset collection point 412 and the wiring of the second circuit layout layer; the control reset pin CRST of the control chip 42 is connected to the reset interface SIM_RST through the wiring of the second circuit layout layer.

[0060] Since the area of ​​the routing area of ​​the first circuit layout layer is not enough, the routing lines related to the ground signal and the clock signal of the user identification card 41 are set in the second circuit layout layer. That is, the identification card ground pins GND of the three user identification cards 41 and the control ground pin CGND of the control chip 42 are respectively connected to the ground interface SIM_GND through the routing lines of the second circuit layout layer. The identification card clock pins CLK of the three user identification cards 41 and the control clock pin CCLK of the control chip 42 are respectively connected to the clock interface SIM_CLK through the routing lines of the second circuit layout layer.

[0061] The signal routing corresponding to different types of pins on the user identification card 41 can adopt different routing methods, and the stability of the communication signal routing, power signal routing and reset signal routing, especially the stability of the communication signal routing, can be ensured by routing on the same circuit layout layer as much as possible and setting the routing on the first circuit layout layer as much as possible. When routing, some power collection points 411 and 412 can be used to gather the wiring of the circuit layout layer on the same layer to avoid using too many through holes to connect the first circuit layout layer and the second circuit layout layer.

[0062] The external structure of the user identity integrated card of the present embodiment is compatible with the existing SIM card. Specifically, the user identity integrated card of the present embodiment is only a hardware package that simulates the physical entity of the SIM card. The internal control chip is a programmable, input- and output-capable embedded technology integrated circuit. The control chip can use a CPU based on the ARM32 architecture, with a Thumb / Thumb2 instruction set and multiple security properties against SPA / DPA attacks; and the control chip can program and modify the function of each pin, which greatly improves the scope of application of the user identity integrated card.

[0063] When the data communication device of the present invention is used, the control chip can switch the user identification card according to the actual situation, thereby ensuring the stability of the communication signal of the Internet of Things device. Figure 5 , Figure 5 The flowchart of the data communication method of the present invention is an embodiment of the data communication method. The data communication method is used in an Internet of Things device based on a cellular network, that is, it is used for the above-mentioned data communication device (Internet of Things device) to communicate with other external terminals. The Internet of Things device includes a user identity identification integrated card, which can be a 12mm*15mm Micro-SIM card or a 15mm*25mm standard SIM card; the user identity identification integrated card includes a plurality of different types of user identity identification cards and a control chip that controls the user identity identification card. The data communication method of this embodiment includes:

[0064] Step S501, detecting the communication status information of the current user identity card through the control chip;

[0065] Step S502, if the communication status information of the current user identity card is abnormal status information, the candidate user identity card is set as the current user identity card, and the candidate user identity card is reset based on a preset rule; and the process returns to step S501;

[0066] Step S503, if the communication status information of the current user identity card is normal status information, the communication value information of the current user identity card is detected by the software tool development kit in the communication module of the Internet of Things device;

[0067] Step S504, if the communication value information of the current user identity card is abnormal data information, the candidate user identity card is set as the current user identity card, the candidate user identity card is reset based on the preset rule, and the process returns to step S501;

[0068] Step S505, if the communication value information of the current user identity card is normal data information, perform data communication operation based on the current user identity card; and after the data communication operation is performed for a set time interval, return to step S501 until the data communication operation is completed.

[0069] The specific process of each step of the data communication method of this embodiment is described in detail below.

[0070] In step S501, the IoT device detects the communication status information of the currently activated user identity identification card in the user identity identification integrated card through the control chip. Since the user identity identification integrated card includes multiple different types of user identity identification cards, but only one user identity identification card can be activated at the same time, that is, all current data communication data is carried out through the activated current user identity identification card; at the same time, the other user identity identification cards are candidate user identity identification cards.

[0071] In this embodiment, the IoT device determines whether it is necessary to switch the user identity card by detecting the communication status information of the current user identity card (i.e., the communication status information of the network corresponding to the current user identity card). Since the control chip can only detect the communication status information of the current user identity card, i.e., the information of network connection and disconnection. The communication status information here can be the network connection and disconnection status information of the circuit domain or packet domain of the public land mobile network (PLMN, Public Land Mobile Network) such as 2G, 3G, 4G, NB-IoT, and network signal information.

[0072] In step S502, when the IoT device detects that the communication status information of the current user identity card is abnormal status information, such as the network connection on / off status information of the current user identity card is disconnection information (PLMN rejection, such as shutdown due to arrears, etc.), or the network signal information of the current user identity card is no signal information (the current network is unavailable, such as the current network coverage is poor, etc.), then other candidate user identity cards are set as the current user identity card, and the candidate user identity card is reset based on the preset rules, that is, the current user identity card is switched. The preset rules here can be to switch the candidate user identity cards in turn to determine the user identity card with the better signal at present. Then return to step S501 to continue to detect the communication status information of the current user identity card after switching.

[0073] In step S503, when the IoT device detects that the communication status information of the current user identity card is normal information, such as the public land mobile network information of the current user identity card is that the network is normal, and the network signal information of the current user identity card is that the network signal is normal, the IoT device detects the communication value information of the current user identity card (i.e., the communication value information of the network corresponding to the current user identity card) through the software tool development kit in the communication module. When the communication status information of the current user identity card is normal, the control chip can call the application in the software tool development kit (SDK, Software Development Kit) in the communication module of the IoT device to detect the communication value information of the current user identity card. The communication value information here can be network signal strength information, detection heartbeat response information, detection heartbeat response delay information, and network standard information, so that the control chip can further optimize the user identity card.

[0074] In step S504, when the Internet of Things device detects that the communication value information of the current user identity card is abnormal data information, such as the network signal strength information of the current user identity card is lower than the first set value (weak signal strength, etc.), the detection heartbeat response information is unresponsive information (no heartbeat response), etc., the detection heartbeat response delay information is greater than the second set value (heartbeat response time is too long, etc.) or the network standard information is low standard information (such as the network standard falls back to 2g state, etc.). Then, based on the command of the communication module of the Internet of Things device, other candidate user identity cards are set as the current user identity card, and the candidate user identity card is reset based on the preset rules, that is, the current user identity card is switched. The preset rules here can be to switch the candidate user identity cards in turn to determine the user identity card with better current signal. Then return to step S501 to continue to detect the communication status information of the current user identity card after switching.

[0075] In step S505, when the Internet of Things device detects that the communication value information of the current user identity card is normal data information, such as the network signal strength information of the current user identity card is high strength information, the detection heartbeat response delay information is also small, and the network standard information is above 3g; the Internet of Things device can perform data communication operations based on the current user identity card, and return to step S501 after the data communication operation is performed at a set time interval, and continue to detect the communication status information of the current user identity card until the data communication operation is completed.

[0076] This completes the data communication process of the data communication method of this embodiment.

[0077] Specifically, in step S504, if the IoT device detects that the communication value information of all user identification cards is normal data information, the IoT device can set a time interval, detect the network signal strength value corresponding to each user identification card through the software tool development kit in the communication module, set the user identification card with the largest network signal strength value as the current user identification card, and perform data communication operations based on the current user identification card. This can further improve the stability of the communication signal of the IoT device.

[0078] The data communication method of this embodiment effectively improves the stability of the communication model of each IoT device in the IoT network by setting multiple user identity cards and setting the switching rules of the user identity cards. The communication status information and communication value information in this embodiment cannot be directly realized through ordinary user identity cards. It must be realized by the application of the third-party control chip or the software tool development kit in the communication module to detect the information of the user identity card. At the same time, the local network switching is also directly controlled by the control chip.

[0079] Please refer to Figure 6 , Figure 6 : is a schematic diagram of the structure of an embodiment of the data communication device of the present invention. The data communication device of this embodiment can be implemented using the above-mentioned data communication method. The data communication device can be set in an Internet of Things device based on a cellular network. The Internet of Things device has a user identity identification integrated card, which includes a plurality of different types of user identity identification cards and a control chip for controlling the user identity identification card. The data communication device 60 includes a communication status information detection module 61, a first setting module 62, a first data communication module 63, a second data communication module 64 and a timing module 65.

[0080] The communication status information detection module 61 is used to detect the communication status information of the current user identity identification card through the control chip; the first setting module 62 is used to reset the current user identity identification card based on preset rules when the communication status information of the current user identity identification card is abnormal status information; the first data communication module 63 is used to perform data communication operations based on the current user identity identification card when the communication status information of the current user identity identification card is normal status information; the second data communication module 64 is used to detect the network signal strength value corresponding to each user identity identification card at a set time interval, set the user identity identification card with the largest network signal strength value as the current user identity identification card, and perform data communication operations based on the current user identity identification card; the timing module 65 is used to return to the communication status information detection module to detect the communication status information of the current user identity identification card after the data communication operation is performed for a set time interval until the data communication operation is completed.

[0081] The first data communication module 63 includes a communication value information detection unit 631, a second setting unit 632 and a first data communication unit 633. The communication value information detection unit 631 is used to detect the communication value information of the current user identity card through the software tool development kit in the communication module of the Internet of Things device; the second setting unit 632 is used to reset the current user identity card based on a preset rule when the communication value information of the current user identity card is abnormal value information; the first data communication unit 633 is used to perform data communication operations based on the current user identity card when the communication value information of the current user identity card is normal value information.

[0082] When the data communication device 60 of this embodiment is used, the communication status information detection module 61 detects the communication status information of the currently activated user identity identification card in the user identity identification integrated card through the control chip. Since the user identity identification integrated card includes multiple different types of user identity identification cards, but only one user identity identification card can be activated at the same time, that is, all current data communication data is carried out through the activated current user identity identification card; at the same time, the other user identity identification cards are candidate user identity identification cards.

[0083] In this embodiment, the communication status information detection module 61 determines whether it is necessary to switch the user identity card by detecting the communication status information of the current user identity card. Since the control chip can only detect the communication status information of the current user identity card, that is, the network connection and disconnection information. The communication status information here can be the network connection and disconnection status information of the circuit domain or packet domain network of the public land mobile network (PLMN, Public Land Mobile Network) such as 2G, 3G, 4G, NB-IoT, and network signal information.

[0084] Then, when the communication status information detection module 61 detects that the communication status information of the current user identity card is abnormal status information, such as the network connection on / off status information of the current user identity card is disconnection information (PLMN rejection, such as shutdown due to arrears, etc.), or the network signal information of the current user identity card is no signal information (the current network is unavailable, such as the current network coverage is poor, etc.), the first setting module 62 sets other candidate user identity cards as the current user identity card, and resets the candidate user identity card based on the preset rules, that is, switches the current user identity card. The preset rules here can be to switch the candidate user identity cards in turn to determine the user identity card with better signal at present. Then, the communication status information detection module 61 is returned to continue to detect the communication status information of the current user identity card after switching.

[0085] When the communication status information detection module 61 detects that the communication status information of the current user identity card is normal information, such as the public land mobile network information of the current user identity card is that the network is normal, and the network signal information of the current user identity card is that the network signal is normal, the communication value information detection unit 631 of the first data communication module 63 detects the communication value information of the current user identity card through the software tool development kit in the communication module of the Internet of Things device. When the communication status information of the current user identity card is normal, the control chip can call the application in the software tool development kit in the communication module of the Internet of Things device to detect the communication value information of the current user identity card. The communication value information here can be network signal strength information, detection heartbeat response information, detection heartbeat response delay information, and network standard information, so that the control chip can further optimize the user identity card.

[0086] When the communication value information detection unit 631 detects that the communication value information of the current user identity card is abnormal data information, such as the network signal strength information of the current user identity card is lower than the first set value (weak signal strength, etc.), the detection heartbeat response information is unresponsive information (no heartbeat response), etc., the detection heartbeat response delay information is greater than the second set value (heartbeat response time is too long, etc.) or the network standard information is low standard information (such as the network standard falls back to 2g state, etc.). Then the second setting unit 632 of the first data communication module 63 sets other candidate user identity cards as the current user identity card based on the command of the communication module of the Internet of Things device, and resets the candidate user identity card based on the preset rules, that is, switches the current user identity card. The preset rules here can be to switch the candidate user identity cards in turn to determine the user identity card with the better signal at present. Then return to the communication status information detection module 61 to continue to detect the communication status information of the current user identity card after switching.

[0087] When the communication value information detection unit 631 detects that the communication value information of the current user identity identification card is normal data information, such as the network signal strength information of the current user identity identification card is high strength information, the detection heartbeat response delay information is also small, and the network standard information is above 3g; the first data communication unit 633 of the first data communication module 63 can perform data communication operations based on the current user identity identification card, and finally the timing module 65 returns to the communication status information detection module 61 after the data communication operation is performed at a set time interval to continue detecting the communication status information of the current user identity identification card until the data communication operation is completed.

[0088] This completes the data communication process of the data communication device 60 of this embodiment.

[0089] The data communication device 60 of this embodiment also includes a second data communication module 64, which is used to detect the network signal strength value corresponding to each user identity identification card at a set time interval, set the user identity identification card with the largest network signal strength value as the current user identity identification card, and perform data communication operations based on the current user identity identification card.

[0090] Specifically, if the communication value information detection unit 631 detects that the communication value information of all user identification cards is normal data information, the second data communication module 64 can set a time interval, detect the network signal strength value corresponding to each user identification card through the software tool development kit in the communication module, set the user identification card with the largest network signal strength value as the current user identification card, and perform data communication operations based on the current user identification card. This can further improve the stability of the communication signal of the Internet of Things device.

[0091] The data communication device of this embodiment effectively improves the stability of the communication model of each IoT device in the IoT network by setting multiple user identity cards and setting the switching rules of the user identity cards. The communication status information and communication value information in this embodiment cannot be directly realized through ordinary user identity cards. It must be realized by the application of the third-party control chip or the software tool development kit in the communication module to detect the information of the user identity card. At the same time, the local network switching is also directly controlled by the control chip.

[0092] The following is a specific example to illustrate the specific working principle of the data communication method and the data communication device of the present invention. Figure 7a as well as Figure 7b , Figure 7a is a timing diagram of communication status information detection of a specific embodiment of the data communication method and data communication device of the present invention, Figure 7b It is a timing diagram of communication value information detection of a specific embodiment of the data communication method and the data communication device of the present invention.

[0093] The IoT device of this embodiment can be various intelligent devices such as machine tool remote control, fleet control, smart home, etc. The IoT device includes a user identity identification integrated card, which is in the form of a 12mm*15mm Micro-SIM (Mini UICC) card or a 15mm*25mm standard SIM card (Plug-in UICC) with an interface compatible with ETSI TS 102 671 and ETSI TS102 221, without any modification to the identification card interface of the IoT device. The user identity identification integrated card includes a plurality of different types of user identity identification cards and a control chip, wherein the user identity identification card is a 5mm*6mm patch SIM card, and the control chip includes various communication pins respectively connected to the user identity identification card and the communication interface, and may also include a memory for storing control chip applications, so as to improve the storage capacity and computing power of the control chip.

[0094] The control chip can obtain the communication status information of the user identity card through the communication data with the user identity card and the communication module of the Internet of Things device, and then the control chip can obtain the communication value information of the user identity card by controlling the chip application and the communication module with the user identity card and the Internet of Things device.

[0095] Please refer to the process of obtaining the communication status information of the user identification card Figure 7a The user identity integrated card includes a first user identity card and a second user identity card. The process of obtaining communication status information and performing data communication operations includes:

[0096] Step S701a, the control chip detects the public land mobile network information of the first user identity card. Here, the control chip can obtain the packet domain network status of the public land mobile network of the current user identity card as disconnection information (the disconnection reason is PLMN rejection) by intercepting an APDU message (Application Protocol Data Unit) between the first user identity card and the communication module of the Internet of Things device.

[0097] Specifically, the control chip can also be used here to intercept the APDU message between the first user identity card and the communication module of the Internet of Things device to obtain the network connection on-off status information, so as to judge the communication status information of the first user identity card through the network connection on-off status information.

[0098] Of course, here you can also use AT commands such as AT+CGREG / +CREG / +CEREG / +CGATT through the application in the software tool development kit in the communication module to detect the connection status between the first user identity card and the communication module of the Internet of Things device to obtain the network connection status information.

[0099] If the public land mobile network information fed back by the first user identity card is rejection information, the cellular network is notified through the communication module of the Internet of Things device, and the first user identity card goes offline.

[0100] Step S702a: The control chip sends a reset request to the communication module and starts the second user identity card.

[0101] In step S703a, the control chip detects the public land mobile network information of the second user identity card. If the public land mobile network information fed back by the second user identity card is normal network information, the communication module of the Internet of Things device notifies the cellular network to use the second user identity card for dial-up connection to perform corresponding data communication.

[0102] Please refer to the process of obtaining the communication value information of the user identification card Figure 7b The user identity integrated card includes a first user identity card and a second user identity card. The process of acquiring communication value information and performing data communication operations includes:

[0103] Step S701b, the control chip detects whether the network signal strength information (Received Signal Strength Indication, Rssi) of the first user identity card is less than 25 through the application in the software tool development kit in the communication module. Here, the application in the software tool development kit in the communication module uses the AT+CSG command to detect the network signal strength of the communication module between the first user identity card and the IoT device.

[0104] Specifically, here, a heartbeat can be sent to the background server and the heartbeat response can be detected through the application in the software tool development kit in the communication module to obtain the heartbeat response information and the heartbeat response delay information, so as to judge the communication value information of the first user identity card through the heartbeat response information and the heartbeat response delay information.

[0105] The network standard information can also be obtained by using the AT+QNWINFO query command in the application in the software tool development kit in the communication module to detect the connection status between the first user identity card and the communication module of the Internet of Things device, so as to judge the communication value information of the first user identity card through the network standard information.

[0106] If the network signal strength information of the first user identity card is less than 25, the application in the software tool development kit in the communication module makes a switching request to the control chip in the user identity integrated card. The application in the software tool development kit calls the standard AT+CSIM / +CLCK command according to the module's support for AT commands, and sends a downlink switching command to the control chip through the communication module to perform a switching operation on the user identity card.

[0107] Step S702b: The control chip completes the user identity card switching, starts the second user identity card, and reads the information of the second identity card.

[0108] Step S703b, the control chip completes the user identity card switching and notifies the software tool development kit. The application in the software tool development kit in the communication module of the Internet of Things device notifies the cellular network to use the second user identity card for dial-up connection. The application in the software tool development kit in the communication module detects the network signal strength information of the second user identity card. If the network signal strength information of the second user identity card is greater than or equal to 25, the Internet of Things device uses the network of the second user identity card.

[0109] This completes the data communication process of the data communication method and the data communication device of this embodiment.

[0110] The user identity identification integrated card, data communication method, device, equipment and system of the present invention effectively improve the communication model stability of each Internet of Things device in the Internet of Things network through the setting of multiple user identity identification cards and the setting of switching rules of user identity identification cards, and solve the technical problem of poor communication signal stability of Internet of Things devices in existing data communication methods and data communication devices; and the interface structure of the user identity identification integrated card in the data communication device of the present invention is the same as the interface structure of the existing user identity identification card, so it is compatible with the interfaces of the user identity identification cards of all existing Internet of Things devices, and users do not need to perform hardware modifications on existing devices using ordinary SIM cards, which greatly improves the scope of use of the data communication device of the present invention.
