[0022] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] Cloud SIM card is a new type of SIM card. Unlike traditional physical SIM cards, it stores the user's phone number in the cloud and communicates with terminal network devices through network connections. The core advantage of cloud SIM card is that it can support multiple network operators, and users do not have to change different physical SIM cards to use different operators' networks. Users can also temporarily choose different local operators based on cloud SIM cards when traveling, avoiding the high cost of international roaming.

[0024] However, for terminal networking devices that do not have a communication module for the cloud SIM card to access the Internet, the cloud SIM card cannot be used to access the Internet, so the use scope of the cloud SIM card is limited.

[0025] Based on this, the embodiments of the present application provide a cloud SIM card providing device and a terminal networking device, which can solve the technical problem that a terminal networking device that does not have a communication module for a cloud SIM card to access the Internet cannot use a cloud SIM card to access the Internet.

[0026] In order to better illustrate the technical solution of the present application, examples are given below.

[0027] like Figure 1 and Figure 2 As shown, the cloud SIM card providing device 100 provided in the embodiment of the present application may include: a communication module 110 , a cloud SIM card placement module 120 and a power management module 130 .

[0028] The communication module 110 has a built-in SIM card for communicating with the cloud server 200 and obtaining cloud SIM card information corresponding to the cloud SIM card allocated by the cloud server 200 .

[0029] The cloud SIM card placement module 120 is used to receive the cloud SIM card information corresponding to the cloud SIM card sent by the communication module 110, and enable the terminal networking device 300 to register and access the Internet based on the SIM card information corresponding to the cloud SIM card.

[0030] The power management module 130 includes a power regulation module 131 and a battery 132 connected to the power regulation module 131; the power regulation module 131 draws power from the SIM card interface of the terminal networking device 300 to charge the battery 132, and adjusts the charging power of the battery based on the load capacity of the SIM card interface of the terminal networking device 300; the battery 132 is used to power the communication module, and the cloud SIM card placement module 120 draws power from the SIM card interface of the terminal networking device 300.

[0031] In one embodiment of the present application, the built-in SIM card of the communication module 110 can be a plug-in card, a patch card, a virtual SIM card (VSIM card) or an electronic SIN card (ESIM card), which is used for network registration of the communication module 110, and when the cloud SIM card providing device needs to be used globally, the built-in SIM card of the communication module 110 can also be a global SIM card.

[0032] The cloud SIM card providing device provided by the present application communicates with the cloud server through the SIM card built in the communication module, obtains the cloud SIM card allocated by the cloud server, and places the cloud SIM card (i.e., the cloud SIM card information corresponding to the cloud SIM card, not the physical card) in the cloud SIM card placement module, so that the terminal networking device can read the cloud SIM card information, and then register to access the Internet through the cloud SIM card, so that when the terminal networking device is a terminal networking device that does not have a communication module for the cloud SIM card to access the Internet, it can also use the cloud SIM card to access the Internet based on the communication module and the cloud SIM card placement module of the cloud SIM card providing device, thereby solving the technical problem that the terminal networking device that does not have a communication module for the cloud SIM card to access the Internet cannot use the cloud SIM card to access the Internet.

[0033] In addition, the cloud SIM card providing device of the present application is also provided with a power management module including a power regulating module and a battery. The power regulating module is used to draw power from the SIM card interface of the terminal networking device to charge the battery, so that the battery can provide the communication module with the large current required for startup, network search and cloud SIM card authentication. At the same time, the power regulating module also adjusts the charging power for charging the battery based on the load capacity of the SIM card interface of the terminal networking device, so that the SIM card interface of the terminal networking device will not be overloaded and powered off due to the large current of the communication module. The cloud SIM card providing device provided in the embodiment of the present application realizes power drawing from the SIM card interface of the terminal networking device based on the power management module, without the need for additional external power supply or user charging, and has the characteristics of small size and easy installation.

[0034] In one embodiment, the power regulation module can adjust the current charging the battery by configuring the resistance value of the resistor to adjust the charging power of the battery so that the SIM card interface of the terminal networking device will not be overloaded and powered off due to the high current of the communication module.

[0035] In one embodiment of the present application, the power regulation module can adjust the current for charging the battery to 18 mA, or less than 18 mA, by configuring the resistance value of the resistor.

[0036] Specifically, Figure 3 The figure shows the service cycle of the communication module. After the communication module is turned on, it performs the network search, cloud card fetching and cloud card authentication functions in sequence to obtain the cloud card, then enters the standby mode, and then returns to the network search (network change), cloud card fetching and cloud card authentication steps based on the identified network change request to achieve the switching of different cloud SIM cards. In this process, the energy consumption of the communication module in one day mainly includes the network change / authentication power consumption and standby power consumption. Among them, one network change / authentication takes about 25s, the average current is about 200mA, and the power consumption is 200mA*25s / 3600s / 24H=0.055mAh. Assuming 24 network changes / authentications a day, the total power consumption of network change / authentication in one day is 0.055mAh*24=1.32mAh. The standby power consumption of the communication module is 4mA*24h=96mAh, and the total power consumption of the communication module in one day is about: 1.32mAh+96mAh=97.32mAh.

[0037] When the power regulating module adjusts the current for charging the battery to 18mA, the power supply capacity of the battery is 18mA*24H=432mAh, which is greater than the total power consumption of the communication module in one day, 97.32mAh. Moreover, by testing terminal networking devices such as mobile phones and tablet computers, when the charging current of the power regulating module is controlled at 18mA, it will not cause abnormal power supply to the SIM card interface of the terminal networking device. Therefore, when the power regulating module adjusts the current for charging the battery to 18mA, the terminal networking device will not be overloaded and powered off due to the large current of the communication module, and can continuously provide a small current power supply for the cloud SIM card providing device, so that the cloud SIM card providing device can take power from the SIM card interface of the terminal networking device, without the need for additional external power supply, and can work stably for a long time without user charging, eliminating the user's maintenance work, and the battery of the power management module of the cloud SIM card providing device can be a small-capacity battery, so that the cloud SIM card providing device has the characteristics of small size.

[0038] In order to make the cloud SIM card providing device compatible with terminal networking devices of different interface types, so as to make it more applicable and more compatible, in one embodiment of the present application, Figure 4As shown, the cloud SIM card providing device can also be provided with a first interface 150 and an interface conversion module 140; the first interface 150 is connected to the cloud SIM card placement module 120 and the power regulation module 131; the interface conversion module is used to establish a physical connection path between the first interface 150 of the cloud SIM card providing device and the SIM card interface 310 of the terminal networking device 300.

[0039] Specifically, the SIM card interface of the terminal networking device 300 can be of various types, such as a full-size SIM card (1FF), a Mini-SIM card (2FF), a Micro-SIM card (3FF), a Nano-SIM card (4FF), etc. In order to make the cloud SIM card providing device 100 compatible with terminal networking devices with different types of SIM card interfaces, a physical connection path can be established between the first interface 150 of the cloud SIM card providing device and the SIM card interface 310 of the terminal networking device 300 through an interface conversion module, that is, the first interface 150 of the cloud SIM card providing device and the SIM card interface 310 of the terminal networking device 300 are physically connected by a cable.

[0040] In one embodiment of the present application, Figure 4 As shown, the interface conversion module includes a second interface 141 and a third interface 142 , the second interface is adapted to the first interface 150 of the cloud SIM card providing device, and the third interface 142 is adapted to the SIM card interface 310 of the terminal networking device 300 .

[0041] In practical applications, in order to make the cloud SIM card providing device 100 compatible with terminal networking devices with different types of SIM card interfaces, the third interface 142 of the interface conversion module may include multiple sub-interfaces, which are physically connected to different SIM card interfaces 310 of different terminal networking devices 300 respectively.

[0042] In a practical application, the interface conversion module can also be a switching cable customized according to the SIM card interface of the terminal networking device and the first interface of the cloud SIM card providing device. This application does not limit the specific structure of the interface conversion module.

[0043] In addition, if Figure 4 As shown, the third interface 142 can also be made into the shape of a SIM card, so that when it is connected to the SIM card interface 310 of the terminal networking device, it can better simulate the effect that the terminal networking device has been inserted with a SIM card.

[0044] For example, the third interface 142 can be designed in size according to the form of the SIM card interface of the terminal networking device in the market, such as full-size SIM card (1FF), Mini-SIM card (2FF), Micro-SIM card (3FF), Nano-SIM card (4FF), to meet the requirements of SIM card insertion and contact. The third interface 142 can also be customized according to the special SIM card interface of the terminal networking device to adapt to various types of terminal networking devices.

[0045] In one embodiment of the present application, the first interface 150 , the second interface 141 , and the third interface 142 may be ISO / IEC 7816 protocol interfaces.

[0046] Among them, ISO and IEC are organizations that formulate world standards. In the field of information technology, ISO / IEC JTC1 has formulated the ISO / IEC 7816 series of standards. Among them, ISO / IEC 7816-3 stipulates the electrical interface and transmission protocol for contact cards. The electrical characteristics of SIM cards include interface definition, power supply, signal structure and information exchange. The interface contains C1 (VCC) power supply, C2 (RST) reset signal, C3 (CLK) clock signal, C5 (GND) ground, C6 (SPU) standard or automatically defined usage and C7 (I / O) serial input and output data. The power supply requirements, signal characteristics, voltage levels, current values, parity conventions, operation procedures and transmission mechanisms under normal operating conditions are all described in detail in the protocol.

[0047] In the embodiment of the present application, since the third interface 142 is adapted to the SIM card interface 310 of the terminal networking device 300, when the third interface 142 is connected to the SIM card interface 310 of the terminal networking device, an effect of simulating that a SIM card has been inserted into the terminal networking device can be achieved. Therefore, the first interface, the second interface and the third interface can draw power from the VCC pin of the SIM card interface 310 of the terminal networking device, and the terminal networking device can be registered for Internet access based on the cloud SIM card information corresponding to the cloud SIM card received by the cloud SIM card providing device.

[0048] In one embodiment of the present application, the cloud SIM card placement module 120 is also used to dynamically receive cloud SIM card information corresponding to the cloud SIM card allocated by the cloud server via the communication module, so that in application scenarios where the cloud SIM card needs to be switched frequently, the terminal networking device can realize timely switching of the cloud SIM card.

[0049] For example, the terminal networking devices used by personnel working in some ports may need to switch back and forth between different cloud SIM cards to meet their communication needs. In this case, the cloud SIM card placement module 120 of the present application can dynamically receive the cloud SIM card information corresponding to the cloud SIM card assigned by the cloud server to achieve dynamic switching of the cloud SIM card. That is, each time the cloud server assigns a new cloud SIM card to the terminal networking device, the terminal networking device can switch to the new cloud SIM card in real time and use the new cloud SIM card to register for Internet access, which can achieve frequent switching of cloud SIM cards.

[0050] In practical applications, when the SIM card interface of the terminal networking device is an ISO / IEC7816 protocol interface, the voltage provided by its VCC pin includes three types of voltages: 5V, 3V and 1.8V. Since the voltage used by the power regulation module to charge the battery is generally 5V, in one embodiment of the present application, Figure 5 As shown, the power management module may further include a voltage conversion unit 133 connected to the power regulation module 131 and the first interface 150, for converting the voltage output by the SIM card interface of the terminal networking device into the charging voltage required by the battery.

[0051] In actual applications, when the voltage output by the VCC pin of the SIM card interface of the terminal networking device is 5V, the voltage conversion unit can directly output the 5V voltage to the power regulation module. When the voltage output by the VCC pin of the SIM card interface of the terminal networking device is 3V or 1.8V, the voltage conversion unit will boost the voltage to 5V and output it to the power regulation module.

[0052] In one embodiment of the present application, the communication module 110 in the above embodiments supports at least two communication units. That is, it supports two or more channel communications, one channel is used for the SIM card built into the communication module 110 to access the network, download cloud SIM card information, remotely authenticate the cloud SIM card, etc.; one channel is used for the terminal networking device connected to the cloud SIM card providing device to access the corresponding cloud SIM card network after the cloud SIM card information is downloaded to the communication module 110.

[0053] In one embodiment of the present application, the communication module 110 in the above embodiments may be a cellular communication module, including two or more communication units, capable of realizing dual-card online standby at the same time. For example, the communication module 110 may be a cellular communication module including a first communication unit and a second communication unit; the first communication unit is used to communicate with the cloud server based on the built-in SIM card and obtain the cloud SIM card information corresponding to the cloud SIM card assigned by the cloud server; the second communication unit is used to provide a channel for the terminal networking device to register for the Internet based on the cloud SIM card.

[0054] Specifically, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the battery 132 supplies power to the communication module 110 and provides the peak current required for startup. After the communication module 110 is powered on, it first registers and connects with the cloud server through the built-in SIM card, which is usually a global SIM card. After successfully connecting to the cloud server 200, the cloud server 200 communicates with the cloud SIM card carrier device 210, and allocates the cloud SIM card in the cloud SIM card carrier device 210 to the communication module 110 according to the set strategy; after receiving the cloud SIM card, the communication module 110 places the cloud SIM card (i.e., the cloud SIM card information corresponding to the cloud SIM card) into the cloud SIM card placement module 120 to complete the scheduling of the cloud SIM card. At the same time, the cloud SIM card placement module 120 communicates with the SIM card interface of the terminal networking device through the first interface, so that the terminal networking device 300 reads the cloud SIM information and registers the cloud SIM card for Internet access through the second communication unit of the communication module 110.

[0055] The embodiment of the present application also provides a terminal networking device. The terminal networking device can be a terminal that needs to use the cloud SIM card providing device in any of the above embodiments to access the Internet. For example, the terminal networking device can be a smart device such as a mobile phone, a tablet computer, and a smart home device such as an air conditioner and a refrigerator. The present application does not limit the specific type of the terminal networking device. The terminal networking device is connected to the cloud SIM card providing device, and registers for Internet access based on the SIM card information corresponding to the cloud SIM card received by the cloud SIM card providing device.
