Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing service obtaining methods for terminals are simplistic and lack flexibility in accessing and obtaining subscription services from networks without prior contracts.
Innovation Solution
A method for terminals to obtain subscription data from a second network, select and access a first network using the subscription data, and receive corresponding services, enabling dynamic service acquisition from third-party entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal signs a contract with a network operator in advance to obtain services, then service reliability is ensured, but service adaptability deteriorates
Solution Approach 1:
The terminal device performs preliminary actions by obtaining subscription data from multiple networks in advance, storing network selection policies and subscription information before actual service access is needed. This allows the terminal to quickly select and access services from appropriate networks without requiring advance contract signing, thus improving service adaptability while maintaining reliable service delivery through pre-validated network options.
2Device complexity
If a terminal uses a simple service obtaining method with advance contracts, then device complexity is reduced, but service versatility deteriorates
Solution Approach 1:
The terminal device performs self-service by autonomously obtaining subscription data from multiple networks, automatically selecting appropriate networks based on stored policies, and independently accessing services without requiring complex manual configuration or advance contract management. The terminal manages its own service acquisition process, reducing the need for complex external coordination while enabling versatile service access across multiple networks.
3Adaptability or versatility
If a terminal accesses multiple networks for service diversity, then service versatility is improved, but system complexity deteriorates
Solution Approach 1:
The system segments the service acquisition process into distinct functional modules: subscription data acquisition from multiple networks, network selection policy storage and management, network selection based on service requirements, and service access execution. This segmentation allows the terminal to handle multiple networks systematically through organized, manageable steps rather than complex simultaneous operations, reducing system complexity while maintaining service versatility.
Solution Approach 2:
The patent introduces subscription data and network selection policies as intermediary elements that mediate between the terminal and multiple networks. These intermediaries contain pre-configured service information and selection criteria, allowing the terminal to automatically determine which network to access for which service without requiring complex real-time decision-making or direct negotiation with each network, thus simplifying the overall system while enabling versatile multi-network access.
