Terminal Network Access Method for Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network access methods often result in intermittent stops or service interruptions when the network quality deteriorates or fails to meet the required service indicators for ongoing services, such as download services, due to variations in transmission rates and quality of service parameters.
Innovation Solution
A network access method where a terminal assesses the network service class of available networks, switches to a higher quality network if the current network's service class is insufficient, and manages bandwidth by simultaneously using multiple networks to ensure continuous service quality and reduce costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal uses a single network for service access, then the device complexity is reduced, but the service reliability deteriorates when network quality deteriorates
Solution Approach 1:
The terminal dynamically selects between single-network and multi-network modes based on service requirements and network conditions. The system transitions from a static single-network approach to a dynamic multi-network approach when service reliability cannot be guaranteed, resolving the contradiction between simplicity and reliability.
Solution Approach 2:
The system changes the network configuration parameter from single-network to multi-network based on service quality requirements. When network quality parameters (transmission rate, delay, jitter) fall below thresholds, the system activates additional networks to maintain service reliability.
2Reliability
If the terminal switches to higher quality networks for all services, then the service quality is improved, but the cost increases
Solution Approach 1:
Different services are assigned to different networks based on their quality requirements. High-quality services (voice, video) use high-service-class networks, while low-quality services (file transfer) use lower-service-class networks. This local quality assignment improves service quality where needed while reducing overall costs.
Solution Approach 2:
The system applies high-quality network access partially - only to services that require it - rather than universally to all services. This partial application of high-quality access resolves the contradiction between service quality and cost.
3Reliability
If the terminal monitors and switches between multiple networks, then the service reliability is improved, but the device complexity increases
Solution Approach 1:
The terminal pre-establishes connections to multiple networks before service interruptions occur. By proactively monitoring network quality and pre-switching to backup networks, the system avoids service interruptions without requiring complex real-time switching mechanisms.
Solution Approach 2:
The system implements automated network quality monitoring and switching without user intervention. The terminal independently evaluates network conditions and performs switching decisions, reducing the complexity of user-side network management while maintaining high service reliability.

AI summary
A network access method and a terminal relate to the communications field, where the method includes obtaining, by the terminal, a priority of a first network service, determining, by the terminal according to a relationship between a network service priority and a network service class, a network service class required for performing the first network service, where the relationship is stored in the terminal, obtaining, by the terminal, a network service class of a first network currently accessed by the terminal, accessing, by the terminal, a second network whose network service class is higher than the network service class of the first network when the network service class of the first network is lower than the network service class required for performing the first network service, and performing the first network service using the second network.
