Multi-Network Service Switching for Seamless Failure Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network services face issues with service disruption and inefficiency due to network failures, particularly when subscribers move out of coverage, leading to delayed network resumption and inadequate handling of unexpected failures.
Innovation Solution
A method and apparatus for providing seamless network services using multiple heterogeneous networks, involving a multi-network management system that synchronizes data across primary and secondary networks, dynamically switching the secondary network to primary in case of failures, and managing network selection based on real-time quality and coverage criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single network is used for service provision, then network simplicity is maintained, but service continuity is compromised when network failure occurs
Solution Approach 1:
The patent applies preliminary action by pre-configuring a secondary network alongside the primary network before any failure occurs. The multi-network management apparatus establishes and maintains a standby secondary network that is ready to take over immediately when the primary network fails, eliminating the need for complex real-time decision-making during failure events.
Solution Approach 2:
The multi-network management apparatus serves as an intermediary between the terminal and multiple networks. It manages the selection, switching, and coordination between primary and secondary networks, abstracting the complexity from the terminal and enabling reliable service continuity without requiring the terminal to handle complex network management logic.
2Reliability
If handover method is used when subscriber moves out of coverage, then service continuity is maintained, but service efficiency is compromised during unexpected failures
Solution Approach 1:
The patent applies preliminary action by pre-establishing a secondary network in standby state before any failure occurs. When a failure happens, the system can immediately switch to the pre-configured secondary network without waiting for network discovery or reconfiguration, thus maintaining both reliability and efficiency.
Solution Approach 2:
The secondary network acts as a cushioning backup that absorbs the impact of primary network failures. By maintaining a ready-to-switch secondary network, the system prevents service disruption and maintains efficiency during unexpected failures, as the backup network is already in place and doesn't require reconfiguration time.
3Speed
If multiple networks are used to increase data transfer rate, then service speed is improved, but network management complexity increases
Solution Approach 1:
The multi-network management apparatus serves as an intermediary that centralizes network management functions. It handles the complexity of monitoring, selecting, and switching between multiple networks (including primary and secondary networks), allowing the terminal to benefit from high-speed data transfer without managing the underlying network complexity directly.
Solution Approach 2:
The multi-network management apparatus provides universal network management capabilities that work across different network types (wired, wireless, 5G, LTE, etc.). It performs multiple functions including network selection, failure detection, handover management, and service continuity ensuring, thereby simplifying the overall system architecture despite using multiple networks.
4Reliability
If service data is synchronized across multiple networks, then service continuity is ensured during failure, but data management complexity increases
Solution Approach 1:
The multi-network management apparatus acts as an intermediary that centralizes data synchronization management. It handles the complexity of synchronizing service data across primary and secondary networks by providing a unified control mechanism, thereby ensuring service continuity during failures without requiring complex distributed synchronization logic at the terminal.

AI summary
Disclosed herein are an apparatus and method for providing a seamless network service based on multiple heterogeneous networks. The method for providing a seamless network service based on multiple heterogeneous networks includes providing, by a multi-network management apparatus, a service transmitted from a server to a terminal over a primary network, synchronizing, by the multi-network management apparatus, service data transmitted over the primary network with a secondary network maintained in a standby state, changing, by the multi-network management apparatus, the secondary network to the primary network as a communication failure between the primary network and the terminal occurs, and providing, by the multi-network management apparatus, the service transmitted from the server to the terminal over the changed primary network.
