Cross-Network Service Continuity for Mobile Core Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication networks face challenges in maintaining service continuity during crisis situations such as cyber-attacks, massive system failures, or temporary national border closures, which existing proprietary solutions struggle to address efficiently due to high design and maintenance efforts.
Innovation Solution
A method and system that monitor the operation of network nodes in a mobile communication network, determine indicator values for network performance, and generate control signals to request resource allocation from another network if performance deviates beyond a predefined limit, allowing for temporary service provision from a secondary network to ensure service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary mechanisms are implemented in the respective network to solve crisis situations, then the network can address crisis situations internally, but the design and implementation and maintenance require a lot of efforts
Solution Approach 1:
The patent implements a universal service continuity function that can operate across different mobile communication networks regardless of vendor-specific proprietary mechanisms. The control function in the first network can request and receive service provisioning from the second network using standardized procedures, making the solution applicable to multiple networks and vendors without requiring custom proprietary implementations in each network.
Solution Approach 2:
The patent introduces an intermediary control function that mediates between the first mobile communication network and the second mobile communication network. This control function manages the service continuity process by generating control signals to request service provisioning and receiving acknowledgments, thereby simplifying the complexity for individual networks by centralizing the coordination logic.
2Reliability
If resources are allocated from another network to ensure service continuity, then service provision can be maintained during crises, but inter-network coordination and resource management become more complex
Solution Approach 1:
The patent segments the service continuity functionality into distinct components: a control function in the first network that monitors service conditions and generates requests, and a control function in the second network that receives requests and provisions services. This segmentation allows each network to maintain its core functions while enabling coordinated resource allocation through standardized interfaces.
Solution Approach 2:
The patent implements a feedback mechanism where the control function in the first network monitors service conditions, compares indicator values against reference values, and generates control signals when deviations are detected. The second network provides feedback through acknowledgments that confirm service provisioning status, enabling dynamic adjustment and ensuring service continuity while simplifying coordination through structured feedback loops.
