Server Notification Interface for Redundant Backup Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In edge computing scenarios, particularly within 5G communication systems, there is a need for redundancy mechanisms to ensure continuous service availability and quality in case of failures, such as those caused by hardware or network outages, which existing technologies do not adequately address.
Innovation Solution
Implementing a notification interface within the server computer arrangement to inform the mobile communication network about a redundant server computer, allowing the network to switch to a backup server in case of failure, ensuring seamless service continuity and predetermined quality of service for mobile communication terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundant server computers are implemented in edge computing scenarios, then service availability and reliability are improved, but system complexity and resource requirements increase
Solution Approach 1:
The patent implements redundancy by creating a copy of the server computer functionality. A second server computer is established as a backup replica of the first server computer, both providing the same application services. This copying approach ensures service continuity while maintaining manageable system complexity through standardized redundant components.
Solution Approach 2:
The notification interface proactively informs the mobile communication network about the existence of the redundant server computer before any failure occurs. This preliminary notification enables the network to pre-configure failover paths and maintain service continuity without requiring complex real-time decision-making during actual failures.
2Reliability
If notification interface is implemented to inform network about backup server, then service continuity is improved, but communication overhead and network complexity increase
Solution Approach 1:
The notification function is extracted as a separate, dedicated interface between the server computer and the mobile communication network. This notification interface specifically handles only the redundancy information, separating it from other communication overhead and enabling efficient, targeted information exchange without burdening the main service communication channels.
3Loss of time
If automatic failover mechanism is implemented, then downtime is reduced, but control complexity and automation requirements increase
Solution Approach 1:
The system implements automatic failover where the mobile communication network autonomously detects server failures and switches traffic to the redundant server without requiring manual intervention. The notification interface enables this self-service capability by providing the network with the necessary information about backup servers, allowing the system to automatically maintain service continuity.

AI summary
According to one embodiment, a server computer (208) of an arrangement of server computers (208) is described comprising at least one application server (208) configured to provide an application to one or more mobile communication terminals (201) accessing the application server (208) via a radio access network (202) of a mobile communication network and a notification interface configured to notify the mobile communication network about another server computer of the arrangement of server computers which the mobile communication network may use as backup for providing the application to the one or more mobile communication terminals (201) in case the server computer (208) fails to provide the application at a predetermined quality level.
