Description

Technical Field

[0001] This invention relates to the field of Internet of Things (IoT) technology, and in particular to an IPv6 home IoT shared network system. Background Technology

[0002] Currently, with the rapid development of IoT technology, more and more smart devices are entering homes. However, existing network technologies such as 4G / 5G mobile networks, NB-IoT (Narrowband Internet of Things), ZigBee, or LoRa (an IoT access layer network transmission technology) have significant shortcomings when dealing with a large number of densely packed IoT devices indoors, such as high cost, weak signal, and susceptibility to congestion. These technologies are typically suitable for low-density outdoor IoT device access scenarios and are insufficient for the needs of large-scale, densely packed indoor device access scenarios. Therefore, developing an efficient, stable, and low-cost home IoT access solution is particularly urgent. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide an IPv6 home IoT shared network system to solve the problems existing in the access of indoor home IoT smart terminals in the prior art. By using independent IPv6 (Internet Protocol version 6) Wi-Fi network SSID and SRv6 network slicing technology, the system solves the problems of high cost, weak signal, and easy congestion faced by a large number of densely packed IoT devices accessing the home, and realizes an efficient, stable, and low-cost solution for smart home appliances to access the home gateway.

[0004] This invention provides an IPv6 home IoT shared network system, comprising: a telecom operator's home broadband access server, a home broadband gateway device, and home IoT smart terminals. The telecom operator adds extra bandwidth to the existing bandwidth capacity of the home broadband gateway for data transmission by the home IoT smart terminals. After the home broadband gateway device connects to the telecom operator's home broadband access server, it defaults to enabling an independent IPv6 Wi-Fi network SSID signal, and the home IoT smart terminals will connect to this SSID by default. With the Wi-Fi network enabled, the home broadband gateway device uses SRv6 to implement IPv6+ network slicing management, creating a dedicated channel that does not occupy home broadband capacity, forming a shared home IoT network system among multiple households. Multiple broadband users' home broadband gateway devices enable the same SSID signal, allowing home IoT smart terminals to access the nearest available network, forming a novel shared networking architecture for IPv6 IoT. The network slicing channel is provided with independent traffic services and billing models by the telecom operator; the home IoT smart terminal includes a Wi-Fi communication module; the home IoT smart terminal is used to search for and connect to the SSID signal within the signal coverage area, and connect to the network through pre-set standardized authentication information; the home IoT smart terminal is also used to obtain a 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 this application, the aforementioned telecommunications operator provides a logical virtual private network (VPN) on the same physical network through its network infrastructure.

[0006] In an optional embodiment of this application, the aforementioned Virtual Private Network provides secure communication and is dedicated to the connection and data transmission between home IoT smart terminals. This channel does not consume home broadband capacity, and is provided with independent traffic services and billing models by a unified operator.

[0007] In an optional embodiment of this application, the aforementioned Virtual Private Network (VPN) is configured with a specific hidden SSID, used only for connection of home IoT smart terminals. This SSID is distinguishable from ordinary Wi-Fi networks, enabling home IoT smart terminals to search for and connect to the private network.

[0008] In an optional embodiment of this application, the aforementioned home broadband gateway device implements IPv6+ network slicing management through SRv6. SRv6 divides the original physical network into multiple logical network slices, forming a flexible, virtual, and mutually isolated logical network between home IoT smart terminal services and non-home IoT smart terminal services.

[0009] In an optional embodiment of this application, the aforementioned home broadband gateway device uses SRv6 technology to insert forwarding instructions into the IPv6 packet header to guide the forwarding of data packets, enabling the data packet sender to specify the routing path of the data packet when it is transmitted in the network, thereby achieving data isolation between home IoT smart terminals and non-home IoT smart terminals.

[0010] In an optional embodiment of this application, the aforementioned home broadband gateway device creates a dedicated channel that does not occupy the home broadband capacity, forming a home IoT shared network system among multiple homes. Multiple broadband user home gateways enable the same SSID signal, allowing home IoT smart terminals to access the nearest one based on signal strength.

[0011] In an optional embodiment of this application, the aforementioned telecom operator's home broadband access server allocates two IPv6 address ranges to the home broadband gateway: one for allocating a unique IPv6 address for non-home IoT smart terminals accessing the home, and the other for allocating a unique IPv6 address for home IoT smart terminals accessing the home.

[0012] In an optional embodiment of this application, the aforementioned home IoT smart terminal automatically connects to the home IoT shared network through pre-set standardized authentication information. The home broadband gateway device uses DHCPv6 technology to allocate a segment of IPv6 addresses for the home IoT smart terminal and assign a unique IPv6 address to the connected home IoT smart terminal.

[0013] In optional embodiments of this application, the aforementioned home broadband gateway device intelligently selects channels to implement a channel scanning function. The home broadband gateway device periodically checks the interference levels of available channels, evaluating channel quality by monitoring channel activity or sending probe signals. When excessive interference is detected on the currently used channel, the home broadband gateway should be able to quickly make a decision to switch the device to a channel with lower interference.

[0014] In an optional embodiment of this application, the above-described IPv6 home IoT shared network system is suitable for the deployment of IoT devices in an indoor environment.

[0015] The embodiments of the present invention bring the following beneficial effects:

[0016] This invention provides an IPv6 home IoT shared network system, including: a telecom operator's home broadband access server, a home broadband gateway device, and a home IoT smart terminal. The home broadband gateway device, as a supplement to the traditional cellular network signal coverage of the telecom operator, acts as a wireless indoor distribution system. It enables an independent IPv6 Wi-Fi (mobile hotspot) network SSID (Service Set Identifier) ​​signal by default and implements IPv6+ network slicing management through SRv6 (Segment Routing IPv6). This channel does not occupy home broadband capacity and is provided with independent traffic services and billing modes by the operator. The home IoT smart terminal's Wi-Fi communication module automatically searches for hidden SSIDs within the signal coverage area. Multiple home gateways automatically select idle channels to avoid signal interference. The home smart terminal achieves automatic network connection through standardized pre-set authentication information, is assigned a unique IPv6 network address, and then connects to the IoT access platform to realize bidirectional direct connection management of devices, creating a more intelligent home application scenario.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Currently, with the rapid development of IoT 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 significant shortcomings when dealing with a large number of densely packed IoT devices indoors, such as high cost, weak signal, and susceptibility to congestion. These technologies are typically suitable for low-density outdoor IoT device access scenarios, and are insufficient for the needs of large-scale, densely packed indoor device access scenarios. Therefore, developing an efficient, stable, and low-cost home IoT access solution is particularly urgent.

[0026] Based on this, the present invention provides an IPv6 home IoT shared network system, including: a telecom operator's home broadband access server, a home broadband gateway device, and a home IoT smart terminal. The home broadband gateway device, as a supplement to the traditional cellular network signal coverage of the telecom operator, acts as a "wireless indoor distribution system." It enables an independent IPv6 Wi-Fi network SSID signal by default and achieves IPv6+ network slicing management through SRv6. This channel does not occupy the bandwidth capacity of traditional home broadband services, and the operator provides independent traffic services and billing modes. The home IoT smart terminal's Wi-Fi communication module automatically connects to the hidden SSID within the signal coverage area. Multiple home gateways automatically select idle channels to avoid signal interference. The home smart terminal achieves automatic network connection through standardized pre-set authentication information, is assigned a globally unique IPv6 network address, and then connects to the IoT access platform to achieve bidirectional direct connection management of devices, creating a more intelligent home application scenario.

[0027] This invention provides a novel shared networking architecture for IPv6 IoT that can be implemented through a home gateway. Multiple broadband users can enable the same SSID signal on their home gateways, allowing home terminals to access the network from the nearest location. This addresses the problems that traditional 4G / 5G mobile networks face when used for low-density outdoor IoT device access scenarios, but when used to cover a large number of indoor IoT devices, such as high cost, weak signal, and congestion.

[0028] To facilitate understanding of this embodiment, a detailed description of an IPv6 home IoT shared network system disclosed in this embodiment of the invention will be provided first.

[0029] Example 1:

[0030] This invention provides an IPv6 home IoT shared network system, see [link to documentation]. Figure 1 The diagram shows the structure of an IPv6 home IoT shared network system, which includes: a telecom operator's home broadband access server, a home broadband gateway device, and a home IoT smart terminal.

[0031] Home broadband gateway devices connect to the home broadband access server of telecommunications operators;

[0032] The home broadband gateway device enables an independent IPv6 Wi-Fi network SSID signal. The home broadband gateway device is used to implement IPv6+ network slicing management through SRv6 technology. Among them, the network slice channel does not occupy the home broadband capacity, and the network slice channel is provided with independent traffic service and billing mode by the telecom operator.

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

[0034] The home IoT smart terminal is also used to obtain the 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.

[0035] See also Figure 2 The diagram shows a connection process between a home broadband gateway device and a smart terminal. Figure 3 The diagram shows a home IoT smart terminal switching its connection to a home gateway.

[0036] In some embodiments, the aforementioned telecommunications operators add extra bandwidth to the existing bandwidth capacity of the home broadband gateway for data transmission of home IoT smart terminals, and allocate two IPv6 address ranges to the home broadband gateway.

[0037] Telecommunications operators add extra bandwidth to the existing bandwidth capacity of home broadband gateways for data transmission to terminal devices. After the home broadband gateway device is connected to the telecommunications operator's home broadband access server, it will by default enable an independent IPv6 Wi-Fi network SSID signal, and home IoT smart terminals will connect to the aforementioned SSID by default.

[0038] In some embodiments, the aforementioned home broadband gateway device implements IPv6+ network slicing management through SRv6, dividing a dedicated network channel from the original physical network for data transmission of home IoT smart terminals.

[0039] After enabling Wi-Fi, the home broadband gateway device utilizes SRv6 to implement IPv6+ network slicing technology, creating a dedicated channel that does not consume home broadband capacity. This forms a shared home IoT network system among multiple households. Multiple broadband users' home gateways enable the same SSID signal, allowing home terminals to connect based on signal strength, creating a novel shared networking architecture for IPv6 IoT. Home IoT smart terminals automatically connect to the shared network through pre-installed standardized authentication information, obtaining a globally unique IPv6 address assigned by the home broadband gateway, and then connecting to the IoT open access platform.

[0040] Step 1: Add additional bandwidth (e.g., 20Mbps) to the existing bandwidth capacity of the home broadband gateway for data transmission to device terminals, and allocate at least two / 64 IPv6 address ranges to the home broadband gateway. One range is used to allocate a unique IPv6 address for non-IoT devices in the home, and the other range is used to allocate a unique IPv6 address specifically for IoT devices in the home.

[0041] Step two: The home broadband gateway device implements IPv6+ network slicing technology using SRv6, carving out a dedicated network channel from the existing physical network for data transmission from home IoT devices. SRv6 segments the IPv6 data packet forwarding path into different segments, inserting segment information into the packet at the beginning of the path. Intermediate nodes forward packets according to the segment information carried in the packet, achieving segmented routing. When the home gateway forwards IPv6 packets sent to it by home IoT devices, it selects appropriate intermediate nodes, generates a segment list, and sets the number of network nodes the data packet traverses and the segment list information according to the IPv6 destination address, thereby guiding the packet forwarding path and behavior, achieving data isolation from non-home IoT devices.

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

[0043] Step 3: By default, the home gateway device enables the independent IPv6 Wi-Fi network SSID (Service Set Identifier) ​​signal (such as "HomeIoT-IPv6").

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

[0045] Step four, as Figure 2 As shown, home IoT devices automatically connect to the IPv6 IoT shared network with SSID "HomeIoT-IPv6" within the signal coverage area.

[0046] In some embodiments, the aforementioned home broadband gateway device utilizes DHCPv6 technology to assign a unique IPv6 address to each home IoT smart terminal, thereby enabling traceability and billing management of the home IoT smart terminal.

[0047] Step 5: After the home IoT device connects to the IPv6 shared network, the home broadband gateway uses Dynamic Host Configuration Protocol (DHCPv6) to select a globally unique IPv6 address from the / 64 IPv6 address range provided by the telecom operator for the home IoT device. The telecom operator's access server determines whether the device is a home IoT device based on its IPv6 address. If so, the traffic used by the device terminal is classified into the independent billing mode 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 signal coverage area of ​​a nearby home.

[0049] Step six, as Figure 3 As shown, when the "HomeIoT-IPv6" network currently connected to a home IoT device fails or is shut down, the home IoT device will automatically switch to a "HomeIoT-IPv6" network within the signal coverage area of ​​a nearby home.

[0050] Step 7, see Figure 4 The diagram shows a multi-home gateway channel selection flowchart. Multiple home gateways automatically select the best channel through an algorithm to reduce signal interference and improve network efficiency.

[0051] Example 2:

[0052] This invention provides a method for automatically selecting an idle channel among multiple home gateways. This embodiment is based on the above embodiments and includes the following steps:

[0053] Step 1, Channel Scanning: Each home broadband gateway device periodically scans the surrounding wireless channels to collect information such as signal strength, interference, and usage of each channel.

[0054] Step two involves 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, and utilization rate. Based on the algorithm's evaluation results, each home gateway device dynamically selects the optimal channel to reduce interference and improve network performance. If a decline in the quality of the currently used channel is detected, the gateway device will automatically switch to another better channel.

[0055] In some embodiments, the aforementioned IPv6 home IoT shared network system is also used to separately bill the traffic usage of home IoT smart terminals through independent traffic services and billing models provided by operators.

[0056] Step 3: Channel switching mechanism. To ensure network connection stability during the switching process, the system is designed with a smooth switching mechanism. When a channel switch is required, the gateway device will notify the connected IoT devices in advance, informing them of the new channel information and guiding the devices to switch gradually, avoiding sudden disconnection.

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

[0058] The aforementioned home broadband gateway device is also used to enable the same SSID signal so that IoT smart terminals in different households can access the optimal network signal source nearby.

[0059] In this embodiment, the home broadband gateway devices enable the same SSID signal, allowing IoT smart terminals in different households to access the nearest high-quality network signal source, thus optimizing the access experience of indoor IoT devices.

[0060] The aforementioned home broadband gateway device uses SRv6 technology to insert forwarding instructions into the IPv6 packet header, so that the data packet specifies the path during transmission.

[0061] In this embodiment, the home broadband gateway device uses SRv6 technology to insert forwarding instructions into the IPv6 packet header, enabling data packets to specify a path during transmission and achieving data isolation between IoT devices and non-IoT devices.

[0062] The aforementioned IPv6 home IoT shared network system is used to assign a unique IPv6 address to each home IoT smart terminal based on DHCPv6 technology.

[0063] In this embodiment, the IPv6 home IoT shared network system uses DHCPv6 technology to assign a globally unique IPv6 address to each home IoT smart terminal, enabling device traceability and security management.

[0064] The aforementioned IPv6 home IoT shared network system is also used to connect IoT devices from multiple homes to the same virtual private shared network, logically dividing the virtual private shared network into multiple network slices.

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

[0066] The aforementioned home IoT smart terminal is used to identify and access a virtual private network (VPN) through authentication information.

[0067] In this embodiment, the home IoT smart terminal can automatically identify and access the shared network through pre-set authentication information, simplifying the device access process and improving the user experience.

[0068] The aforementioned IPv6 home IoT shared network system is also used to separately bill the traffic usage of IoT devices through independent traffic services and billing models provided by operators.

[0069] The IPv6 home IoT shared network system in this embodiment can bill IoT devices' traffic usage separately through independent traffic services and billing models provided by operators, thereby avoiding the impact on home broadband capacity.

[0070] In some embodiments, the above-described IPv6 home IoT shared network system is suitable for deployment of home IoT smart terminals in an indoor environment.

[0071] The IPv6 home IoT shared network system in this embodiment is particularly suitable for large-scale IoT device deployment in indoor environments, providing stable and efficient data transmission services, and forming a brand-new shared networking architecture for IPv6 IoT.

The home broadband gateway device, as a supplement to the traditional cellular network signal coverage of the telecom operator, acts as a wireless indoor distribution system. It defaults to enabling an independent IPv6 Wi-Fi network SSID signal and implements IPv6+VPN network slicing via SRv6. This channel does not occupy home broadband capacity and is provided with independent traffic services and billing modes by the operator. The home IoT smart terminal's Wi-Fi communication module automatically searches for the strongest hidden SSID signal. Multiple home gateways automatically select idle channels to avoid signal interference. The home smart terminal achieves automatic network connection through standardized pre-set authentication information, is assigned a globally unique IPv6 network address, and then connects to the IoT access platform to achieve bidirectional direct connection management of devices, creating a more intelligent home application scenario.
