[0002] At present, with the rapid development of Internet of Things technology, more and more smart devices are entering homes. However, existing network technologies such as 4G / 5G (fourth generation mobile communication technology / fifth generation mobile communication technology) mobile networks, NB-IoT (NarrowBand Internet of Things), ZigBee (ZigBee protocol) or LoRa (an Internet of Things access layer network transmission technology) have obvious shortcomings when facing a large number of densely populated Internet of Things devices indoors, such as high cost, weak signal, easy congestion and other problems. These technologies are usually suitable for outdoor low-density Internet of Things device access scenarios, and it is difficult to meet the needs of indoor large-scale and dense device access scenarios. Therefore, it is particularly urgent to develop an efficient, stable and low-cost home Internet of Things access solution. Summary of the invention

After the home broadband gateway device is connected to the telecom operator's home broadband access server, the home broadband gateway device turns on an independent IPv6 Wi-Fi network SSID signal by default, and the home Internet of Things smart terminal will connect to the above SSID by default. After turning on the Wi-Fi network, the home broadband gateway device is used to implement IPv6+ network slicing management through SRv6, create a dedicated channel that does not occupy the home broadband capacity, and form a home Internet of Things shared network system between multiple families. The home broadband gateway devices of multiple broadband users turn on the same SSID signal, allowing the home Internet of Things smart terminal to access nearby, forming a new shared networking architecture for the IPv6 Internet of Things. The network slice channel is provided with independent traffic services and billing models by telecom operators; the home IoT smart terminal contains a Wi-Fi communication module; the home IoT smart terminal is used to search and connect to the SSID signal within the signal coverage area, and connect to the network through preset standardized authentication information; the home IoT smart terminal is also used to obtain the unique IPv6 network address assigned by the home broadband gateway device using DHCPv6 technology, and access the IoT access platform based on the IPv6 network address.

[0005] In an optional embodiment of the present application, the above-mentioned telecommunications operator provides a logical virtual private network (VPN) on the same physical network through its network infrastructure.

[0006] In an optional embodiment of the present application, the above virtual private network provides secure communication and is dedicated to the connection and data transmission between home IoT smart terminals.

[0010] In an optional embodiment of the present application, the above-mentioned home broadband gateway device creates a dedicated channel that does not occupy the home broadband capacity, forming a home Internet of Things shared network system among multiple households. Multiple broadband user home gateways turn on the same SSID signal, allowing home Internet of Things smart terminals to access nearby based on signal strength.

[0011] In an optional embodiment of the present application, the above-mentioned telecom operator's home broadband access server allocates two IPv6 address segments to the home broadband gateway, one for allocating a unique IPv6 address for access of non-home IoT smart terminals in the home, and the other for allocating a unique IPv6 address for access of home IoT smart terminals.

[0012] In an optional embodiment of the present application, the above-mentioned home Internet of Things smart terminal is automatically connected to the home Internet of Things shared network through preset standardized authentication information, and the home broadband gateway device uses DHCPv6 technology to allocate an IPv6 address segment provided for the home Internet of Things smart terminal, and allocates a unique IPv6 address for the connected home Internet of Things smart terminal.

[0013] In an optional embodiment of the present application, the above-mentioned home broadband gateway device intelligently selects channels to implement a channel scanning function. The home broadband gateway device periodically checks the interference of available channels and evaluates the quality of the channels by monitoring channel activities or sending detection signals. When it is detected that the interference of the currently used channel is too high, the home broadband gateway should be able to make a decision quickly and switch the device to a channel with lower interference.

[0014] In an optional embodiment of the present application, the above-mentioned IPv6 home Internet of Things shared network system is suitable for the deployment of Internet of Things devices in indoor environments.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] At present, with the rapid development of Internet of Things technology, more and more smart devices are entering homes. However, existing network technologies such as 4G / 5G mobile networks, NB-IoT, ZigBee or LoRa have obvious shortcomings when facing a large number of densely populated IoT devices indoors, such as high cost, weak signal, and easy congestion. These technologies are usually suitable for low-density outdoor IoT device access scenarios, but are difficult to meet the needs of large-scale, densely populated device access scenarios indoors. Therefore, it is particularly urgent to develop an efficient, stable, and low-cost home IoT access solution.

[0026] Based on this, an IPv6 home Internet of Things shared network system provided by an embodiment of the present invention includes: a telecom operator's home broadband access server, a home broadband gateway device and a home Internet of Things smart terminal. The home broadband gateway device serves as a supplement to the telecom operator's traditional cellular network signal coverage and acts as a "wireless indoor distribution system". An independent IPv6 Wi-Fi network SSID signal is enabled by default, and IPv6+ network slicing management is implemented through SRv6. The channel does not occupy the broadband capacity of traditional home broadband services, and the operator uniformly provides independent traffic services and billing modes. The Wi-Fi communication module of the home Internet of Things smart terminal automatically connects to the hidden SSID within the signal coverage range, and automatically selects idle channels between multiple home gateways to avoid signal interference. The home smart terminal realizes automatic network connection through standardized preset authentication information, allocates a globally unique IPv6 network address, and then connects to the Internet of Things access platform to realize two-way direct connection management of devices and create a smarter home application scenario.

[0027] The embodiments of the present invention can realize a new shared networking architecture for IPv6 Internet of Things through a home gateway. The home gateways of multiple broadband users turn on the same SSID signal, and home terminals can access the nearest one, solving the problem that traditional 4G / 5G mobile networks are suitable for outdoor low-density Internet of Things device access scenarios, but covering a large number of indoor Internet of Things devices will face problems such as high cost, weak signal, and easy congestion.

[0028] To facilitate understanding of this embodiment, an IPv6 home Internet of Things shared network system disclosed in an embodiment of the present invention is first introduced in detail.

[0029] Embodiment 1:

[0030] The embodiment of the present invention provides an IPv6 home Internet of Things shared network system, see Figure 1 A structural schematic diagram of an IPv6 home Internet of Things shared network system is shown, and the IPv6 home Internet of Things shared network system includes: a telecom operator's home broadband access server, a home broadband gateway device, and a home Internet of Things smart terminal;

[0031] The home broadband gateway device is connected to the telecom operator's home broadband access server;

[0032] The home broadband gateway device starts an independent IPv6 Wi-Fi network SSID signal. The home broadband gateway device is used to implement IPv6+ network slicing management through SRv6 technology. The network slicing channel does not occupy the home broadband capacity. The network slicing channel is provided with independent traffic services and billing models by telecom operators.

[0033] The home IoT smart terminal includes a Wi-Fi communication module; the home IoT smart terminal is used to search and connect to the SSID signal within the signal coverage range, and connect to the network through preset authentication information;

[0034] The home IoT smart terminal is also used to obtain the IPv6 network address allocated by the home broadband gateway device using DHCPv6 technology, and access the IoT access platform based on the IPv6 network address.

[0035] See also Figure 2 A schematic diagram of a connection process between a home broadband gateway device and a smart terminal is shown and Figure 3 A schematic diagram of a home Internet of Things smart terminal switching to connect to a home gateway is shown.

[0036] In some embodiments, the telecom operator adds additional bandwidth for home IoT smart terminal data transmission based on the original bandwidth capacity of the home broadband gateway, and allocates two IPv6 address segments to the home broadband gateway.

[0037] Telecom operators add additional bandwidth to the original bandwidth capacity of the home broadband gateway for device terminal data transmission. After the home broadband gateway device is connected to the telecom operator's home broadband access server, an independent IPv6 Wi-Fi network SSID signal is enabled by default, and the home IoT smart terminal will connect to the above SSID by default.

[0038] In some embodiments, the above-mentioned home broadband gateway device implements IPv6+ network slicing management through SRv6, and divides a network channel dedicated to data transmission of home IoT smart terminals from the original physical network.

[0039] After the Wi-Fi network is turned on, the home broadband gateway device implements IPv6+ network slicing technology through SRv6, creates a dedicated channel that does not occupy the home broadband capacity, and forms a home IoT shared network system between multiple families. Multiple broadband user home gateways turn on the same SSID signal, allowing home terminals to access the nearest one according to the signal strength, forming a new shared networking architecture for IPv6 IoT. The home IoT smart terminal automatically connects to the shared network through the preset standardized authentication information, obtains the globally unique IPv6 address assigned by the home broadband gateway, and then connects to the IoT open access platform.

[0040] Step 1: Add additional bandwidth (for example, 20Mbps) to the original bandwidth capacity of the home broadband gateway for device terminal data transmission, and allocate at least two / 64 IPv6 address segments to the home broadband gateway, one for allocating a unique IPv6 address for non-IoT device access in the home, and the other for allocating a unique IPv6 address specifically for IoT device access in the home.

[0041] Step 2: The home broadband gateway device implements IPv6+ network slicing technology through SRv6, and divides a network channel dedicated to data transmission of home IoT devices from the original physical network. SRv6 cuts the IPv6 data message forwarding path into different segments, and inserts segment information into the message at the starting point of the path. The intermediate nodes forward according to the segment information carried in the message to achieve segment routing. When the home gateway forwards the IPv6 message sent to it by the home IoT device, it selects a suitable intermediate node, generates a segment list, and sets the number of network nodes and segment list information that the data message passes through according to the IPv6 destination address, thereby guiding the forwarding path and behavior of the message and isolating the transmission data from non-home IoT devices. .

[0042] In some embodiments, the above-mentioned IPv6 home IoT shared network system includes multiple home broadband gateway devices that enable the same IPv6 Wi-Fi network SSID signal by default.

[0043] Step 3: The home gateway device turns on an independent IPv6 Wi-Fi network SSID (Service Set Identifier) ​​signal (such as "HomeIoT-IPv6") by default.

[0044] In some embodiments, the above-mentioned home IoT smart terminal is used to detect and connect to a home IoT gateway device of an IPv6 Wi-Fi network SSID signal within the signal coverage range.

[0045] Step 4: Figure 2 As shown, the home IoT device automatically connects to the IPv6 IoT shared network with SSID "HomeIoT-IPv6" within the signal coverage range.

[0046] In some embodiments, the above-mentioned home broadband gateway device uses DHCPv6 technology to allocate a unique IPv6 address to each home IoT smart terminal to achieve traceability and billing management of the home IoT smart terminal.

[0047] Step 5: After the home IoT device is connected to the IPv6 shared network, the home broadband gateway uses the Dynamic Host Configuration Protocol (DHCPv6) to select from the / 64 IPv6 address segment provided by the telecom operator for the home IoT device and allocate a globally unique IPv6 address to the connected home IoT device. The telecom operator's access server determines whether the device is a home IoT device based on the device's IPv6 address. If so, the traffic used by the device terminal is included in the independent billing model of the IPv6 home IoT shared network.

[0048] In some embodiments, when the IPv6 Wi-Fi network to which the home IoT smart terminal is connected fails or is shut down, the home IoT device switches to the same SSID IPv6 Wi-Fi network within the coverage of a nearby home signal.

[0049] Step 6: Figure 3 As shown, when the "HomeIoT-IPv6" network to which the current home IoT device is connected fails or is shut down, the home IoT device will automatically switch to the "HomeIoT-IPv6" network within the signal coverage range available to nearby homes.

[0050] Step 7, see Figure 4 The schematic diagram of a multi-home gateway channel selection flow chart is shown, in which the optimal channel is automatically selected among multiple home gateways through an algorithm to reduce signal interference and improve network efficiency.

[0051] Embodiment 2:

This embodiment is implemented on the basis of the above embodiment. The method for automatically selecting an idle channel between multiple home gateways includes the following steps:

[0053] Step 1: Channel scanning. Each home broadband gateway device will regularly scan the surrounding wireless channels to collect information such as the signal strength, interference, and usage rate of each channel.

[0054] Step 2: Intelligent algorithm decision-making. The system uses intelligent algorithms (such as machine learning algorithms) to analyze the comprehensive performance indicators of each channel, including signal strength, interference level, utilization rate, etc. Based on the evaluation results of the algorithm, each home gateway device will dynamically select the current optimal channel to reduce interference and improve network performance. If it detects that the quality of the currently used channel has deteriorated, the gateway device will automatically switch to other better channels.

[0055] In some embodiments, the above-mentioned IPv6 home IoT shared network system is also used to separately bill the traffic usage of the home IoT smart terminal through the independent traffic service and billing model provided by the operator.

[0056] Step 3: Channel switching mechanism. In order to ensure the stability of network connection during the switching process, the system has designed a smooth switching mechanism. When the channel needs to be switched, the gateway device will notify the connected IoT device in advance, inform the new channel information, and guide the device to switch gradually to avoid sudden disconnection.

[0057] The home broadband gateway device in this embodiment has a channel scanning function. Through an intelligent algorithm and a smooth switching mechanism, each home gateway device will dynamically select the current optimal channel.

[0058] The above-mentioned home broadband gateway device is also used to open the same SSID signal so that the IoT smart terminals of different households can access the optimal network signal source nearby.

[0060] The above-mentioned home broadband gateway device inserts a forwarding instruction into the IPv6 message header through the SRv6 technology, so that the data message specifies a path during the transmission process.

[0061] The home broadband gateway device in this embodiment uses SRv6 technology to insert forwarding instructions into the IPv6 message header, so that the data message can specify a path during transmission, thereby achieving data isolation between IoT devices and non-IoT devices.

[0064] The above-mentioned IPv6 home IoT shared network system is also used to connect IoT devices of multiple households to the same virtual private shared network, and logically divide the virtual private shared network into multiple network slices.

[0065] The IPv6 home IoT shared network system in this embodiment supports connecting IoT devices of multiple households to the same virtual private network (VPN), logically dividing multiple network slices, thereby enhancing network and data transmission isolation.

[0066] The above-mentioned home Internet of Things smart terminal is used to identify and access a virtual private shared network through authentication information.

[0067] The home IoT smart terminal in this embodiment can automatically identify and access the shared network through preset authentication information, which simplifies the device access process and improves the user experience.
