Base Station Dynamic Failover to Secondary Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recovery planning in telecommunications systems faces challenges in enhancing recovery capability without significantly increasing network resources, particularly in ensuring continuous communication between base stations and exchanges, especially during failures or disasters, due to high costs and resource constraints.
Innovation Solution
Implementing a method where base stations monitor the status of their primary exchange connections and trigger a transition to a secondary exchange if issues are detected, optimizing resource use by minimizing the need for continuous heartbeat or state information exchange and allowing automatic re-registration of user terminals once the connection is restored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional duplication and redundancy schemes are implemented to improve recovery capability, then reliability of communications is improved, but network resources and cost significantly increase
Solution Approach 1:
The patent implements dynamic failover capability where base stations can switch between primary and secondary exchanges based on connection status. The system transitions from static redundancy to dynamic adaptation, allowing the network to activate backup resources only when needed, thus optimizing resource utilization while maintaining reliability.
Solution Approach 2:
The patent pre-configures base stations with knowledge of secondary exchanges and establishes backup connection paths in advance. This preliminary action enables rapid failover without requiring resource allocation during actual failure events, reducing both resource consumption and recovery time.
2Reliability
If continuous heartbeat or state information exchange is implemented to monitor exchange status, then reliability is improved, but network resource consumption increases
Solution Approach 1:
The patent implements periodic status checks instead of continuous monitoring. Base stations exchange status information at defined intervals with primary exchanges, reducing constant communication overhead while maintaining adequate surveillance of connection health. This periodic action balances monitoring effectiveness with resource conservation.
3Loss of time
If automatic transition to secondary exchange is implemented upon failure detection, then recovery time is reduced, but system complexity increases
Solution Approach 1:
The patent enables base stations to autonomously detect connection failures and automatically initiate failover to secondary exchanges without requiring complex centralized control or manual intervention. This self-service capability reduces recovery time while the automation is achieved through relatively simple local decision-making logic at each base station.
Data Source
AI summary
A recovery scheme where a base station monitors state of interoperation with a primary exchange. When the primary exchange becomes unavailable, active services may be lost, but the base station sends an activation request message to a secondary exchange that has access to base station configuration information of the base station. The secondary exchange uses the base station configuration information to activate the base station, and user terminals in the base station cell may begin to registrate to the system. Recovery capability of communications can be achieved with optimized use of network resources.
