Communication Path Selection for Radio Access Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems fail to select an optimal communication path that satisfies the service requirements of radio terminals, leading to inefficient resource utilization due to the lack of consideration for service characteristics and backhaul characteristics when interworking between different radio access apparatuses.
Innovation Solution
A communication system that acquires service characteristic information and backhaul characteristic information to determine the type of communication path for downlink user data, allowing for the selection of paths that go through one or both of the first and second radio access apparatuses, optimizing the use of available resources based on the specific service requirements and backhaul characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If communication systems use conventional path selection without considering service characteristics, then the system operation is simple, but resource utilization efficiency deteriorates
Solution Approach 1:
The system changes the parameter of path selection by introducing service characteristic information and backhaul characteristic information as decision criteria. The communication path is dynamically selected based on matching service requirements (bandwidth, delay, reliability) with available path characteristics, transforming the selection from a simple conventional process to an optimized parameter-based decision process that improves resource utilization efficiency.
2Productivity
If communication systems select optimal paths based on service characteristics, then resource utilization efficiency is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary action by pre-acquiring and storing service characteristic information and backhaul characteristic information before actual communication path selection. This advance preparation allows the path selection process to efficiently match service requirements with available paths using stored information, reducing the computational complexity during real-time operation while maintaining high resource utilization efficiency.
3Reliability
If communication systems consider service requirements for path selection, then communication performance is improved, but information processing complexity increases
Solution Approach 1:
The system applies local quality by acquiring and processing service characteristic information and backhaul characteristic information specifically for path selection purposes. Instead of processing all possible information globally, the system focuses on the specific local qualities (bandwidth, delay, reliability characteristics) that are relevant to communication path optimization, thereby improving communication performance while controlling information processing complexity.

AI summary
A communication system includes a first radio access apparatus, a second radio access apparatus, and a radio terminal that is enabled to simultaneously communicate with the first radio access apparatus and the second radio access apparatus. The communication system acquires service characteristic information that indicates a characteristic of a service provided to the radio terminal and determines a type of a communication path for downlink user data used for provision of the service to the radio terminal, from among a plurality of types of communication paths, based on the service characteristic information.
