Split Bearer Configuration for Mobile-Fixed Access Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing architecture for integrating mobile and fixed communication systems faces challenges in adding new functions to the mobile core and integrating radio bearers, making it difficult to efficiently support both types of communication while minimizing additional functions in the mobile network.
Innovation Solution
A communication system with a split bearer configuration that performs protocol conversion, separating the communication path into mobile and non-mobile access paths using a base station master station apparatus, mobile access slave station apparatuses, and non-mobile access slave station apparatuses, with a user gateway for packet format conversion and pseudo cell information management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a function is added to the mobile core to support fixed access accommodation, then the mobile and fixed communication can be integrated, but the complexity of the mobile core increases and adjustment processes with conventional functions increase
Solution Approach 1:
The system segments the mobile core functionality from the fixed access accommodation by introducing a separate fixed access accommodation base station apparatus. This apparatus handles fixed access-specific functions independently, while the mobile core maintains its conventional functions, thus avoiding complexity increase in the mobile core while enabling integration capability.
Solution Approach 2:
The fixed access accommodation base station apparatus acts as an intermediary between the mobile core and fixed access networks. It translates and adapts protocols between mobile and fixed access, enabling integration without requiring modifications to the mobile core's conventional functions.
2Adaptability or versatility
If the mobile core is connected to all base stations for centralized control, then comprehensive management is achieved, but it becomes difficult to implement small-scale new functions for only necessary parts
Solution Approach 1:
The system divides base stations into different types (conventional mobile base stations and fixed access accommodation base stations). The fixed access accommodation base station can be deployed selectively in specific locations where fixed access is needed, without requiring changes to the mobile core or other base stations, thus enabling selective function deployment.
Solution Approach 2:
The fixed access accommodation base station introduces local quality by providing fixed access-specific capabilities only in specific geographic locations or network segments where they are required, rather than uniformly across the entire mobile network, allowing targeted deployment without system-wide complexity.
3Adaptability or versatility
If radio bearers for mobile access and fixed access are separated, then each access type can be optimized independently, but a new function is required to integrate the two radio bearers when both communications are used together
Solution Approach 1:
The fixed access accommodation base station merges the mobile radio bearer and fixed access bearer into a unified communication path. It receives data from the mobile core via mobile radio access and forwards it through fixed access networks, effectively combining both access types into a single integrated flow without requiring additional integration functions.
