CPE Backup Communication Switching for Data Transmission Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Customer Premise Equipment (CPE) experiences 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 in CPE and switching data transmission to a backup communication device through local communication interfaces, enabling continuous data exchange without handshaking or parameter coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If CPE uses a single communication device for data transmission, then device complexity is reduced, but reliability deteriorates when communication failure occurs
Solution Approach 1:
The system pre-configures backup communication devices and establishes standby connections before primary communication failures occur. When failure is detected, the backup device is immediately activated without requiring complex real-time negotiation or reconfiguration, thus maintaining reliability while limiting complexity to pre-established pathways.
Solution Approach 2:
The CPE acts as an intermediary that manages both primary and backup communication devices, automatically switching between them based on communication state. This intermediary role allows the system to maintain reliability through redundancy while the CPE's control logic manages the complexity of coordinating multiple devices.
2Reliability
If CPE implements backup communication devices, then reliability improves, but device complexity increases
Solution Approach 1:
The communication system is segmented into independent primary and backup pathways. Each pathway can function autonomously, and the CPE manages them as separate modules. This segmentation allows reliability to improve through redundancy while keeping complexity manageable by dividing the communication function into discrete, independently configurable segments.
Solution Approach 2:
The backup communication device operates in a standby state without requiring active coordination or configuration from the primary device. When failure occurs, the backup device automatically activates using pre-configured parameters, eliminating the need for complex real-time coordination between multiple devices and reducing overall system complexity.
3Reliability
If real-time communication state detection is implemented, then reliability improves, but use of energy increases
Solution Approach 1:
Instead of continuous real-time monitoring, the system employs periodic communication state detection at critical transition points (e.g., during data transmission, handover, or connection establishment). This periodic approach maintains reliability by detecting failures when they matter most while significantly reducing energy consumption compared to continuous monitoring.
Solution Approach 2:
The system implements feedback mechanisms that trigger communication state detection based on events or anomalies rather than continuous monitoring. When normal operation is detected, monitoring remains minimal; when anomalies occur (e.g., transmission errors, connection timeouts), the system activates comprehensive state detection and switches to backup pathways, thus maintaining reliability while minimizing energy expenditure during normal operation.
