Gateway Device Automatic Networking via Bridge Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cascade networking, user equipment connected to different gateway devices cannot communicate with each other due to distinct network parameters and IP addresses, limiting interconnectivity within a home network.
Innovation Solution
All gateway devices in a home network are set to use the same network parameter, allowing user equipment to connect to the same local area network segment, enabling communication among multiple devices by switching to a bridge mode and synchronizing network parameters across gateway devices.

Engineering Contradiction Analysis
1Area of stationary object
If cascade networking is used to expand network coverage, then network coverage area is improved, but interconnectivity between user equipment on different network segments deteriorates
Solution Approach 1:
The patent merges multiple network segments into a single unified network by making the gateway device transparent to IP address translation. The gateway forwards packets between network segments without modifying IP addresses, allowing user equipment on different segments to communicate as if they were on the same network, thus combining the benefits of extended coverage with seamless interconnectivity.
Solution Approach 2:
The gateway device acts as an intermediary that transparently forwards packets between different network segments. It receives packets from user equipment, determines the destination network segment, and forwards the packet without changing the source or destination IP addresses, enabling communication across segments while maintaining the illusion of a single network.
2Adaptability or versatility
If different network segments are used for different gateway devices, then network scalability is improved, but communication between user equipment on different segments deteriorates
Solution Approach 1:
The patent combines multiple network segments into a functionally unified network by implementing transparent IP forwarding at the gateway. User equipment on different segments can communicate reliably because the gateway forwards packets without IP address translation, preserving the original source and destination addresses and enabling direct communication across segments.
Solution Approach 2:
The gateway device performs multiple functions: it routes packets between network segments, maintains a mapping between user equipment and network segments, and forwards packets transparently without IP address modification. This multi-functionality enables both network scalability and reliable communication between segments.
3Ease of operation
If transparent IP forwarding is implemented, then interconnectivity between user equipment is improved, but device complexity increases
Solution Approach 1:
The gateway device automatically performs IP address translation and packet forwarding without requiring manual configuration for each user equipment or network segment. It maintains a mapping table that is automatically updated as user equipment connects and disconnects, and uses this mapping to transparently forward packets, reducing the need for complex manual setup while maintaining interconnectivity.

AI summary
This application provides a method and an apparatus for automatic networking of a gateway device. The method includes: after a first gateway device is connected to a second gateway device, determining, by the first gateway device, whether the second gateway device and the first gateway device are in a same home network; when the first gateway device and the second gateway device are in the same home network, switching, by the first gateway device, to be a bridge device of the second gateway device; receiving, by the first gateway device, a network parameter sent by the second gateway device, where the network parameter includes an SSID of the second gateway device and an Internet Protocol IP address assigned by the second gateway device to the first gateway device, and the IP address is an address in a network segment corresponding to the SSID; and performing, by the first gateway device, network configuration on the first gateway device according to the network parameter.
