Terminal Multi-RAT Selection for Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in ensuring continuity and quality of service across different environments due to the lack of cooperation among various Radio Access Technologies (RATs), leading to performance and convenience issues for users who must manually select between them.
Innovation Solution
A service communication method that enables a terminal to autonomously select and utilize multiple RATs based on acquired network capabilities, service requirements, and terminal conditions, establishing connections and adjusting communication modes to optimize performance and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration is used to select radio access networks, then user control and simplicity are maintained, but service continuity and quality across different environments deteriorate
Solution Approach 1:
The terminal device autonomously performs RAT selection and network switching based on pre-configured service requirements and real-time network conditions, eliminating the need for continuous manual user intervention while ensuring service continuity across different access networks
Solution Approach 2:
Service requirements and selection criteria are pre-configured in the terminal device before actual network usage, enabling the terminal to automatically make optimal RAT selection decisions in real-time without requiring manual configuration during service operation
2Device complexity
If multiple RATs work without cooperation, then device complexity and implementation difficulty are reduced, but service performance and user convenience deteriorate
Solution Approach 1:
The patent merges multiple RATs (e.g., WLAN and cellular networks) into a coordinated multi-RAT system where the terminal can simultaneously utilize multiple access technologies for a single service, achieving service continuity and enhanced performance through cooperative operation rather than isolated RAT functionality
3Reliability
If automatic RAT selection is implemented, then service continuity and performance are improved, but terminal complexity and processing requirements increase
Solution Approach 1:
Service requirements, network conditions, and selection criteria are pre-configured and stored in the terminal before actual network operation. This preliminary configuration enables the terminal to automatically perform RAT selection based on simple real-time comparisons against pre-established criteria, reducing the need for complex real-time processing algorithms

AI summary
Embodiments provide a service communication method. The method uses multiple Radio Access Technologies (RATs), and includes that: a terminal receives network capabilities of the multiple RATs; the terminal selects at least two RATs for a service of the terminal from the multiple RATs according to the network capabilities; and the terminal performs communication of the service by using the at least two RATs. In the embodiments, the terminal selects the at least two RATs for the service, so that manual setting of a user can be avoided, and thereby performance and convenience of the multiple RATs can be improved.
