CPE MAC Address Table for Portal Website Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for promoting portal websites on Customer Premise Equipment (CPE) devices, such as home gateways, are ineffective in repeatedly presenting the operator's portal website to multiple devices within a network, as they rely heavily on IP addresses and do not account for devices that remain constantly online, leading to lower promotion frequency and flexibility.
Innovation Solution
A method utilizing MAC address-based redirection rules, where an address association table links MAC addresses to IP addresses, allowing the CPE to set and manage portal website redirection rules, enabling regular promotion of the operator's portal website by querying the table after a WAN connection is established and using a timer to maintain and update redirections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If portal website promotion is performed based on IP address, then the promotion method is simple to implement, but only the first device to access the Internet can have the portal website presented, while other terminals cannot be promoted
Solution Approach 1:
The patent segments the identification of devices from IP addresses to MAC addresses. By using MAC addresses which are unique to each network interface card, the system can individually identify and promote the portal website to each terminal device separately, even when multiple devices share the same network connection through NAT.
Solution Approach 2:
The patent introduces a MAC address table as an intermediary data structure between the CPE and terminal devices. This table stores mappings between terminal MAC addresses and their corresponding IP addresses, enabling the CPE to track and manage promotion status for each device independently while maintaining the IP-based communication framework.
2Duration of action of stationary object
If the user keeps the CPE home gateway on-line continuously, then Internet access is maintained, but the portal website promotion frequency decreases because promotion only occurs on first access
Solution Approach 1:
The patent implements periodic portal website promotion by setting a timer that triggers promotion at regular intervals. When the timer expires, the CPE checks the MAC address table for connected devices and presents the portal website to them, ensuring continuous promotion even when devices remain online without disconnecting.
Solution Approach 2:
The patent establishes a feedback mechanism where the CPE monitors device connection status through the MAC address table and timer events. When a device is detected as connected and the timer expires, the system feedbacks by presenting the portal website, creating a closed-loop promotion system that adapts to continuous online scenarios.
3Ease of operation
If portal website promotion is performed only on first Internet access, then the promotion method is easy to implement, but it cannot promote to devices that access Internet repeatedly without disconnection
Solution Approach 1:
The patent performs preliminary actions by pre-establishing the MAC address table and configuring the timer mechanism before promotion needs to occur. The MAC address table is continuously updated with device information, and the timer is pre-configured with the promotion interval, so that when promotion is needed, the system can immediately act without complex real-time detection.
Solution Approach 2:
The patent ensures continuous promotion capability by maintaining the MAC address table continuously updated with device connection information and keeping the timer mechanism running constantly. This allows the system to promote the portal website to any connected device at any time, rather than only on first access, maintaining continuous promotional effectiveness.

AI summary
A method and CPE for promoting a portal website base on an MAC address are provided. The method includes: after a WAN connection is established successfully, CPE query a pre-established address association table; when a corresponding MAC address terminal in the address association table is connected with the CPE, the CPE set a portal website redirection rule to the IP address of the corresponding MAC address terminal; and when the terminal accesses an external network, the CPE promote the portal website according to the set portal website redirection rule. The present invention can realize the promotion of a portal website at selectable intervals, and improve the promotion frequency and flexibility of the portal website.
