Internet Access Box Multi-Path Data Routing via Wireless Backhaul
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Internet access boxes connected via xDSL networks face challenges in boosting throughput due to difficulties in placing 4G routers for optimal wireless reception and limitations in Wi-Fi frequency bands for inter-router traffic, which restricts speed enhancement.
Innovation Solution
A data routing method that connects an Internet access device to a local wireless network generated by the access box, using DHCP requests with a 'EXTWAN' parameter to allocate network addresses and generate routing tables for distributing data streams between wired and mobile communication networks, enabling Multi-Path Transport Control Protocol (MPTCP) sessions to optimize data routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the 4G router is connected by a cable to the xDSL router, then the connection is stable, but it is difficult to place it in a place where the reception of the wireless communication network is the best
Solution Approach 1:
The patent replaces the mechanical cable connection with a wireless communication link. The 4G router connects to the xDSL router via Wi-Fi instead of a physical cable, substituting the mechanical connection system with an electromagnetic field-based communication system. This allows the 4G router to be placed anywhere within wireless range while maintaining connection stability.
2Ease of operation
If the 4G router is connected via Wi-Fi to the xDSL router, then placement flexibility is improved, but a frequency band must be condemned for inter-router traffic, which limits the speed
Solution Approach 1:
The patent segments the wireless communication into two separate frequency bands: one band (e.g., 2.4 GHz) is dedicated to inter-router traffic between the xDSL router and 4G router, while another band (e.g., 5 GHz) is reserved for client device connectivity. This segmentation prevents frequency band contention and allows full-speed data transmission for both purposes simultaneously.
3Device complexity
If a single network interface is used, then the device complexity is low, but the network throughput is limited
Solution Approach 1:
The 4G router is configured to perform multiple functions simultaneously: it acts as both a wireless client (connecting to the xDSL router via Wi-Fi) and a wireless access point (providing connectivity to client devices). This multi-functionality allows the system to leverage both wired and wireless networks for internet access, increasing overall throughput without requiring complex multi-interface configuration on each device.

AI summary
The present invention relates to a method for routing data through an Internet access box (3) connected to the Internet via a wired communication network (300) by means of the steps for: (a) connecting an Internet access device (1), which is connected to the Internet via a mobile communication network (100), to a local wireless network generated by the Internet access box (3); (b) sending a network address assignment request to the access box (3), said request including a parameter representing a capability of the device (1) for providing access to the Internet; (c) generating a table associated with the device (1) for routing via the mobile communication network (100), said table, associated with the device (1), and at least one table, associated with the access box (3) for routing via the wired communication network (300), being stored on a data storage means (32) of the access box (3); and (d) routing said data via the wired communication network (300) and/or the mobile communication network (100) by using the routing tables stored on the data storage means (32) of the access box (3).
