[0026] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to 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.

[0027] A cloud SIM card is a newly emerging SIM card. Different from traditional physical SIM cards, it stores the user's phone number in the cloud and communicates with the terminal networking device through a network connection. The core advantage of the cloud SIM card is that it can support multiple network operators, and users do not have to replace different physical SIM cards to use the networks of different operators. When traveling, users can also temporarily select different local operators based on the cloud SIM card, avoiding the high costs of international roaming.

[0028] However, for a terminal networking device that does not have a communication module for the cloud SIM card to access the Internet, it cannot use the cloud SIM card to access the Internet, which limits the scope of use of the cloud SIM card.

[0029] 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 without a communication module for the cloud SIM card to access the Internet cannot use the cloud SIM card to access the Internet.

[0030] In order to better illustrate the technical solution of the present application, the following will be illustrated by way of embodiments.

[0031] As Figure 1 and Figure 2 shown, the cloud SIM card providing device 100 provided by the embodiments of the present application may include: a communication module 110, a cloud SIM card placement module 120, and a power management module 130.

[0032] Among them, the communication module 110 is built-in with a SIM card, and is used to communicate with the cloud server 200 and obtain the cloud SIM card information corresponding to the cloud SIM card allocated by the cloud server 200.

[0033] 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.

[0034] 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, charges the battery 132, and adjusts the charging power for the battery based on the load capacity of the SIM card interface of the terminal networking device 300; the battery 132 is used to supply power to the communication module, and the cloud SIM card placement module 120 draws power from the SIM card interface of the terminal networking device 300.

[0035] In an embodiment of the present application, the SIM card built into the communication module 110 can be a pluggable card, a patch card, a virtual SIM card (VSIM card), or an electronic SIM card (eSIM card), and is used for network registration of the communication module 110. Moreover, when the cloud SIM card providing device needs to be used globally, the SIM card built into the communication module 110 can also be a global SIM card.

[0036] The cloud SIM card providing device provided by the embodiment of the present application communicates with the cloud server through the SIM card built into 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 and access the Internet through the cloud SIM card. When the terminal networking device is a terminal networking device without 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, solving the technical problem that the terminal networking device without a communication module for the cloud SIM card to access the Internet cannot use the cloud SIM card to access the Internet.

[0037] Moreover, the cloud SIM card providing device of the present application is also provided with a power management module including a power regulation module and a battery. The power regulation module draws power from the SIM card interface of the terminal networking device to charge the battery, so that the battery can provide the large current required for the communication module to start up, search for a network, and authenticate the cloud SIM card. At the same time, the power regulation module also adjusts the charging power for 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 by the embodiment of the present application realizes drawing power from the SIM card interface of the terminal networking device based on this power management module, without additional external power supply and without user charging, and has the characteristics of small volume and easy installation.

[0038] In one embodiment, the power adjustment module can adjust the current for charging the battery by configuring the resistance value of the resistor, so as to adjust the charging power for charging the battery, 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.

[0039] In one embodiment of the present application, the power adjustment 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.

[0040] Specifically, as Figure 3 shown is a schematic diagram of the service cycle of the communication module. After the communication module is powered on, it sequentially executes functions such as network search, obtaining the cloud card, and cloud card authentication to obtain the cloud card, and then enters the standby mode. Then, based on the recognized network switching request, it returns to the steps of network search (network switching), obtaining the cloud card, and cloud card authentication to realize the switching of different cloud SIM cards. In this process, the energy consumed by the communication module in one day mainly includes power consumption for network switching / authentication and standby power consumption. Among them, one network switching / authentication takes about 25 s, the average current is about 200 mA, and the power consumption is 200 mA * 25 s / 3600 s / 24 H = 0.055 mAh. Assuming 24 network switchings / authentications in one day, the total power consumption for network switching / authentication in one day is 0.055 mAh * 24 = 1.32 mAh. The standby power consumption of the communication module is 4 mA * 24 h = 96 mAh. The total electrical energy consumed by the communication module in one day is approximately: 1.32 mAh + 96 mAh = 97.32 mAh.

[0041] When the power adjustment module adjusts the current for charging the battery to 18 mA, the power supply capacity of the battery is 18 mA * 24 H = 432 mAh, which is greater than the total electrical energy consumed by the communication module in one day, 97.32 mAh. And, through testing terminal networking devices such as mobile phones and tablet computers, when the charging current of the power adjustment module is controlled at 18 mA, it will not cause abnormal power supply of the SIM card interface of the terminal networking device. Therefore, when the power adjustment module adjusts the current for charging the battery to 18 mA, it can not only prevent the terminal networking device from being overloaded and powered off due to the large current of the communication module, but also continuously provide small-current power supply for the cloud SIM card providing device, enabling the cloud SIM card providing device to obtain power from the SIM card interface of the terminal networking device, without the need for additional external power supply or user charging, and can work stably for a long time, eliminating the user's maintenance work. Moreover, the battery of the power management module of the cloud SIM card providing device can be a small-capacity battery, making the cloud SIM card providing device have the characteristic of small volume.

[0042] In order to enable the cloud SIM card providing device to be compatible with terminal networking devices of different interface types, so that its application range is wider and its compatibility is better, in one embodiment of the present application, as Figure 4As shown in the figure, the cloud SIM card providing device may 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 adjustment 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.

[0043] Specifically, the SIM card interfaces of the terminal networking device 300 can have various types, such as full-size SIM cards (1FF), Mini-SIM cards (2FF), Micro-SIM cards (3FF), Nano-SIM cards (4FF), etc. In order to enable the cloud SIM card providing device 100 to be 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 the interface conversion module, that is, a physical cable connection is made between the first interface 150 of the cloud SIM card providing device and the SIM card interface 310 of the terminal networking device 300.

[0044] In an embodiment of the present application, as Figure 4 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.

[0045] In practical applications, in order to enable the cloud SIM card providing device 100 to be compatible with terminal networking devices with different types of SIM card interfaces, the third interface 142 of the interface conversion module can include multiple sub-interfaces, which are respectively physically connected to different SIM card interfaces 310 of different terminal networking devices 300.

[0046] In a practical application, the interface conversion module can also be a patch cord customized according to the SIM card interface of the terminal networking device and the first interface of the cloud SIM card providing device. The present application does not limit the specific structure of the interface conversion module.

[0047] In addition, as Figure 4 shown, the third interface 142 can also be made in 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 of the SIM card being inserted into the terminal networking device.

[0048] For example, the third interface 142 can be designed in terms of size according to the form of the SIM card interface of the market terminal networking device, such as a full-size SIM card (1FF), a Mini-SIM card (2FF), a Micro-SIM card (3FF), or a Nano-SIM card (4FF), to meet the requirements for SIM card insertion, removal, 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.

[0049] In an embodiment of the present application, the first interface 150, the second interface 141, and the third interface 142 can be ISO / IEC 7816 protocol interfaces.

[0050] Among them, ISO and IEC are organizations that formulate world standards. In the field of information technology, ISO / IEC JTC1 has formulated a series of ISO / IEC 7816 standards. Among them, ISO / IEC 7816-3 stipulates the electrical interface and transmission protocol for contact cards. The electrical characteristics of the SIM card include interface definition, power supply, signal structure, and information exchange. The interface includes a C1 (VCC) power supply, a C2 (RST) reset signal, a C3 (CLK) clock signal, a C5 (GND) ground, a C6 (SPU) standard or automatically defined usage, and a C7 (I / O) serial input / output data. The power supply requirements, signal characteristics, voltage levels, current values, parity conventions, operation procedures, and transmission mechanisms in the normal operation state are described in detail in the protocol.

[0051] 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, the effect of simulating that the 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 obtain power from the VCC pin of the SIM card interface 310 of the terminal networking device, and the terminal networking device can be registered to access the Internet based on the cloud SIM card information corresponding to the cloud SIM card received by the cloud SIM card providing device.

[0052] In an embodiment of the present application, the cloud SIM card placement module 120 is further configured to dynamically receive, via the communication module, the cloud SIM card information corresponding to the cloud SIM card allocated by the cloud server, so that in an application scenario where the cloud SIM card needs to be frequently switched, the terminal networking device can achieve timely switching of the cloud SIM card.

[0053] For example, for the personnel working at some ports, the terminal networking devices they use may need to switch different cloud SIM cards back and forth 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 allocated by the cloud server, realizing the dynamic switching of the cloud SIM card. That is, each time the cloud server allocates 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, register and access the Internet using the new cloud SIM card, and can realize the frequent switching of the cloud SIM card.

[0054] In practical applications, when the SIM card interface of the terminal networking device is an ISO / IEC7816 protocol interface, the voltages provided by its VCC pins include three types of voltages: 5V, 3V, and 1.8V. Since the voltage for the power regulation module to charge the battery is generally 5V, in an embodiment of the present application, as Figure 5 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.

[0055] In practical 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 boosts the voltage to 5V and then outputs it to the power regulation module.

[0056] In an 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 built-in SIM card of the communication module 110 to access the network, download the cloud SIM card information, and 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.

[0057] In an 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, and can realize dual-card simultaneous online standby. 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 allocated by the cloud server; the second communication unit is used to provide a channel for the terminal networking device to register and access the Internet based on the cloud SIM card.

[0058] Specifically, asFigure 2 , Figure 3 , Figure 4 and Figure 5 As shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 , the battery 132 powers the communication module 110 to provide the peak current required for startup. After the communication module 110 is powered on, it first registers and connects to the cloud server through the built-in, usually global SIM card. After successfully connecting to the cloud server 200, the cloud server 200 communicates with the card-carrying device 210 of the cloud SIM card, and allocates the cloud SIM card in the card-carrying device 210 of the cloud SIM card to the communication module 110 according to the set policy; 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 can read the cloud SIM information and perform cloud SIM card registration and Internet access through the second communication unit of the communication module 110.

[0059] 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 for Internet access. For example, the terminal networking device can be a smart device such as a mobile phone or a tablet computer, as well as a smart home device such as an air conditioner or a refrigerator. The specific type of the terminal networking device is not limited in the present application. The terminal networking device includes a SIM card interface, which is used to connect to the cloud SIM card providing device and enable the terminal networking device to register and access the Internet based on the SIM card information corresponding to the cloud SIM card received by the cloud SIM card providing device.
