Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication systems face challenges in providing reliable services, especially for critical services like emergency calls, due to fluctuations in radio transmission quality between user equipment and base stations, leading to service unavailability.
Innovation Solution
A method and apparatus for heterogeneous network systems that allow user equipment to temporarily switch from one network to another, utilizing the capabilities of a second network system to ensure service continuity and quality, by performing registration, determining service feasibility, and executing a system switchover process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile communication system relies on a single network system to provide services, then the system complexity is low, but the service availability deteriorates when radio transmission quality drops below a certain level
Solution Approach 1:
The patent combines multiple network systems (first network system and second network system) into a unified service delivery architecture. The user equipment can be simultaneously connected to both networks, and the system can dynamically switch or aggregate services from either network, thereby improving service availability while managing complexity through coordinated multi-network operation.
Solution Approach 2:
The patent implements dynamic service provisioning where the network can adaptively switch between different network systems based on service requirements, network status, and radio transmission quality. The system dynamically determines whether to provide services through the first network system or switch to the second network system, enabling flexible response to changing conditions and maintaining high service availability.
2Reliability
If the system switches between different network systems to ensure service continuity, then the service quality improves, but the ease of operation deteriorates due to the complexity of system switchover processes
Solution Approach 1:
The patent implements automated system switchover mechanisms where the network system automatically determines and executes network switching without requiring manual user intervention. The base station or network controller autonomously monitors service quality, evaluates network status, and performs seamless switchover between network systems, thereby maintaining service continuity while preserving ease of operation for end users.
Solution Approach 2:
The patent introduces a network controller or base station as an intermediary that manages the complexity of multi-network coordination. This intermediary handles registration, service determination, and switchover processes, shielding users from the operational complexity while ensuring seamless service continuity through automated network management.
3Adaptability or versatility
If the system uses multiple network systems to provide services, then the adaptability improves, but the device complexity increases due to multiple connections and switching mechanisms
Solution Approach 1:
The patent creates a universal service delivery framework where the user equipment and network infrastructure can operate across multiple network systems (different technologies, frequencies, or operators). The system is designed to handle various service types and network configurations through a unified multi-network architecture, enabling broad adaptability while managing device complexity through standardized protocols and procedures.
