Information acquisition system and communication method thereof
[ technical field ] A method for producing a semiconductor device
The present invention relates to a Narrow Band cellular Internet of Things (NB-IoT) device, and more particularly, to an information acquisition system and a communication method thereof.
[ background of the invention ]
Narrow-band cellular internet of things (NB-IoT) is one of the important branches of internet of things. The NB-IoT supports low power devices to communicatively connect to the cellular wide area network. Among them, the cellular wide Area Network is also called a Low-power wide-Area Network (LPWAN). In other words, the NB-IoT devices have at least low power consumption and the ability to transmit data over long distances.
However, the NB-IoT device needs to install a Subscriber Identity Module (SIM) card so that the NB-IoT device supports the connection service of the LPWAN. The small size NB-IoT devices employ embedded SIM (eSIM) cards, i.e., the SIM cards installed in the NB-IT devices are not removable.
When the NB-IoT device has the SIM card, although the NB-IoT device can communicate with the remote server through the SIM card, the NB-IoT device cannot transmit a large amount of data and needs a transmission method with a larger bandwidth, and the SIM card is built in the NB-IoT device and cannot be replaced or taken out for other devices.

[ detailed description ] embodiments
In some embodiments, please refer to fig. 1. The information retrieval system 90 includes an information retrieval device 50 and a host device 60.
As shown in fig. 1, the information retrieving device 50 includes: a first control unit 501, a first connection unit 502, an information retrieving unit 503, a storage unit 504, a low power networking unit 505, and a SIM card 506. The first control unit 501 is coupled to the information retrieving unit 503, the storage unit 504, the first connection unit 502, the low power networking unit 505 and the SIM card 506, respectively.
The first control unit 501 is used to control the operations of other components (e.g., the first connection unit 502, the information retrieving unit 503, the storage unit 504, and the low power networking unit 505). The first connection unit 502 can be used to communicate with the host device 60.
The information retrieving unit 503 is used for retrieving environmental data. The storage unit 504 is used for storing the environment data captured by the information capturing unit 503. In some embodiments, the environmental data may be, for example, live video and/or audio.
The low power networking unit 505 is used to connect to a network. In some embodiments, the low power networking unit 505 may be, for example, a narrow frequency cellular internet of things (NB-IoT) module or the like.
The SIM card 506 stores an authentication information. This authentication information is suitable for the low power networking unit 505 to connect to the network accordingly. In other words, the information retrieving device 50 can utilize the identity authentication information stored in the SIM card 506 to establish a network connection E02 with a base station 100 through the low power networking unit 505, as shown in fig. 2. In some embodiments, the identity authentication information comprises: an Integrated Circuit Card Identity (ICCID), an International Mobile Subscriber Identity (IMSI) code, security authentication and encryption information, temporary information related to the home network, and a list of services to which the user has access.
In some embodiments, please refer to fig. 1. The host device 60 includes: a second control unit 601, a second connection unit 602, and a high power networking unit 603. The second control unit 601 is coupled to the second connection unit 602 and the high power networking unit 603, respectively.
The second control unit 601 is used to control the operations of other elements (e.g., the second connection unit 602 and the high power networking unit 603).
The second connection unit 602 can be used to establish a communication link with the first connection unit 502 of the information capturing device 50. In one embodiment, the communication link may be a hardware wired link. In an exemplary embodiment, the first connection unit 502 and the second connection unit 602 can be mutually connected USB connection interfaces. For example, the first connection unit 502 has a USB2.0 or USB3.0 jack, and the second connection unit 602 has a USB2.0 or USB3.0 plug. In another example, the first connection unit 502 can be a charging connector, and the second connection unit 602 can be a charging cradle that mates with a plug. In another embodiment, the communication link may be a wireless link. In an example, the first connection unit 502 and the second connection unit 602 may be Bluetooth (BT) modules matched with each other. In another example, the first connection unit 502 and the second connection unit 602 may be Wireless Fidelity (WiFi) modules.
The high power networking unit 603 is used for connecting a network. In some embodiments, the high power networking unit 603 may be, for example, a fourth generation mobile communication technology (4G) module or a fifth generation mobile communication technology (5G) module, etc.
In some embodiments, referring to fig. 1 to fig. 3, the first connection unit 502 or the second connection unit 602 detects a communication link N11 between the host device 60 and the information capturing device 50 (step s101), so as to determine whether a communication link N11 is established between the host device 60 and the information capturing device 50.
For example, it is assumed that the first connection unit 502 of the information capturing device 50 is a cradle (charging dock), and the second connection unit 602 of the host device 60 is a transmission line. The information acquisition device 50 is mounted on the charging stand and connected to the host device 60 via a transmission line. The charging seat is provided with a plurality of PINs (PIN). When the information capturing device 50 is connected to the charging cradle, the charging cradle has a detection circuit for detecting whether the information capturing device 50 is installed on the charging cradle via the PIN. When the PIN of the cradle detects an electrical signal transmitted to the transmission line, the host device 60 also receives the electrical signal from the PIN through the transmission line, indicating that the information capturing device 50 and the host device 60 establish a communication link.
Referring to fig. 3, fig. 3 is a flowchart illustrating an operation of the information capturing system. When the communication link is established, the high power networking unit 603 obtains the authentication information in the SIM card 506 via the communication link (step s103) and uses the authentication information to establish a network connection E01 with the base station by the high power networking unit 603 (step s105), as shown in fig. 4. For example, when the communication link is established between the host device 60 and the information capturing device 50, the second control unit 601 of the host device 60 causes the high power networking unit 603 to obtain the authentication information stored in the SIM card 506 of the information capturing device 50 through the communication link, and the high power networking unit 603 sends the broadcast signal with the authentication information to the base station 100. When the base station 100 receives the broadcast signal and confirms that the identity authentication information is valid, the base station 100 returns a confirmation signal to start establishing a bidirectional network connection.
In some embodiments, when the host device 60 establishes a communication link with the information capturing device 50, the information capturing device 50 stops the operation of the low power networking unit 503. For example, the first control unit 501 of the information capturing apparatus 50 sends a shutdown signal to the low power networking unit 505 to shut down (disable) the low power networking unit 505, that is, the low power networking unit 505 is temporarily not operating.
In some embodiments, host device 60 may have a SIM card driver 6010, as shown in fig. 4. The SIM card driver 6010 is coupled to the second wire connection unit 602. The SIM card driver 6010 is configured to drive the SIM card 506, so as to allow the high power networking unit 603 to read the authentication information stored in the SIM card 506 of the information capturing device 50 through the communication link.
In other embodiments, on the contrary, when the communication link is not established, if the information retrieving device 50 is to be connected to the network, the low power networking unit 505 obtains the identification information in the SIM card (step s107), and the low power networking unit 505 establishes the network connection E02 with the base station 100 using the identification information (step s109), as shown in fig. 2. In some embodiments of step s109, the low power networking unit 505 of the information retrieving apparatus 50 sends a broadcast signal with the authentication information. When the base station 100 receives the broadcast signal and confirms that the authentication information is valid, the base station 100 sends a confirmation signal back to the information capturing device 50 to start establishing the bidirectional network connection E02.
In some embodiments, the information capturing device 50 may have a SIM card driver 5010, as shown in fig. 2. The SIM card driver module 5010 couples the SIM card 506. The SIM card driver 5010 is used to drive the SIM card 506, so as to allow the low power networking unit 505 to read the authentication information stored in the SIM card 506.
In an exemplary embodiment, the SIM card driver 5010 can be integrated into the first control unit 501. In another example, the SIM card driver module 5010 may be disposed outside the first control unit 501 and coupled to the first control unit 501.
In an exemplary embodiment, the SIM card driver module 6010 may be integrated in the second control unit 601. In another example, the SIM card driver module 6010 may be disposed outside the second control unit 601 and coupled to the second control unit 601.
In some embodiments, the information capturing device 50 can be, for example, a portable electronic device, a wearable camera (body work camera), a portable camera, or a smart phone. The present invention is illustrative of possible embodiments, but is not limited thereto.
In some embodiments, the host device 60 may be, for example, a personal computer, a smart phone, a tablet computer, a notebook computer, or a server. The present invention is illustrative of possible embodiments, but is not limited thereto.
In other embodiments, the base station 100 includes, but is not limited to, a site Controller, an Access Point (AP), a Radio Network Controller (RNC), or any other peripheral device capable of operating in a wireless environment. The present invention is illustrative of possible embodiments, but is not limited thereto.
The invention provides an information acquisition system and a communication method thereof, which can share identity authentication information in a built-in SIM card of an information acquisition device to a host device when the information acquisition device (such as an NB-IoT device) is connected with the host device, so that the host device can establish network connection with a base station through the identity authentication information in the SIM card, and the information acquisition device can carry out data synchronization through a high-power-consumption networking unit of the host device so as to save the power consumption of the device.
However, the above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all simple equivalent changes and modifications made according to the claims and the contents of the patent specification should be included in the scope of the present invention.
