Customer Premise Equipment Failover for Continuous Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Customer Premise Equipment (CPE) may experience abnormal communication states due to disasters or failures, leading to interruptions in data transmission with application devices.
Innovation Solution
The method involves detecting abnormal wireless communication states and switching data transmission to a backup communication device through local communication interfaces, enabling continuous data exchange without handshaking or coordinating communication parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission relies on a single primary communication device (CPE), then the communication system is simple and cost-effective, but the system reliability deteriorates when the primary device fails or encounters disasters
Solution Approach 1:
The patent pre-configures backup communication devices and establishes backup data transmission paths before failures occur. When the primary CPE fails, the system can immediately switch to the pre-prepared backup path without requiring complex real-time decision-making or coordination, thus improving reliability while keeping the system structure relatively simple.
Solution Approach 2:
The patent introduces a network manager as an intermediary that coordinates between the primary CPE, backup communication devices, and application devices. This intermediary handles the complexity of path switching and device coordination, allowing the overall system to achieve high reliability without requiring each component to be overly complex.
2Reliability
If the system implements backup communication devices and path switching mechanisms, then data transmission continuity is improved, but the device complexity and configuration overhead increase
Solution Approach 1:
The patent enables the backup communication devices and switching mechanisms to operate autonomously based on pre-configured rules and conditions. When the primary CPE fails, the system automatically detects the failure and switches to backup paths without requiring manual intervention or complex coordination protocols, thereby maintaining ease of operation while ensuring transmission continuity.
3Reliability
If the system requires handshaking and communication parameter coordination during path switching, then communication accuracy is maintained, but the switching time and loss of time increase
Solution Approach 1:
The patent pre-configures communication parameters and establishes backup transmission paths before failures occur. This preliminary setup eliminates the need for time-consuming handshaking and parameter coordination during actual path switching, as all necessary configurations are already in place and can be activated immediately when the primary path fails.

AI summary
A method and a system (600) for maintaining data transmission continuity are provided. The method includes: detecting, by first customer premise equipment (11), a first wireless communication state of the first customer premise equipment, in which the first customer premise equipment serves an application device (199); and in response to determining that the first wireless communication state is abnormal, executing, by the first customer premise equipment, at least one of the following operations: guiding first data from the application device to a first backup communication device (31); and guiding second data from the first backup communication device to the application device.
