6G RAN Service Bridging Through eDU for Legacy 5G Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in integrating with legacy networks due to hierarchical architectures that lead to resource wastage and difficulty in customizing services, especially when transitioning to service-based systems like 6G, where operators may not offer a full suite of services.
Innovation Solution
A service-based network architecture where a 6G radio access network (RAN) provides a 5G core network service to user equipment (UE) through an enhanced distributed unit (eDU), enabling UE to communicate using a service context and message format compatible with the 5G CU, allowing seamless connectivity to legacy networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hierarchical architecture is used to integrate with legacy networks, then compatibility with existing infrastructure is maintained, but resource utilization efficiency deteriorates and service customization becomes difficult
Solution Approach 1:
The patent segments the network architecture into service-based functional units that can be independently deployed and managed. Instead of a rigid hierarchical structure, the network is divided into modular service components that can be selectively activated, enabling customization while reducing overall system complexity through distributed functionality.
Solution Approach 2:
The patent introduces dynamic service registration and discovery mechanisms that allow network services to be flexibly added, removed, or modified without reconfiguring the entire hierarchical architecture. This dynamic approach enables service customization while maintaining compatibility with legacy infrastructure through adaptive service deployment.
2Productivity
If a service-based protocol is implemented for 6G RAN to connect to 5G core network, then resource utilization and spectrum usage improve, but compatibility with legacy network architecture deteriorates
Solution Approach 1:
The patent introduces a service-based interface layer that acts as an intermediary between the 6G RAN and the 5G core network. This intermediary layer translates service-based protocols into legacy-compatible signaling, enabling efficient resource utilization through modern service architecture while maintaining reliable compatibility with existing 5G infrastructure.
Solution Approach 2:
The patent implements a universal service-based interface that can simultaneously support multiple network generations and service types. This multi-functional interface enables 6G RAN to connect to 5G core network using efficient service-based protocols while maintaining backward compatibility with legacy architectures through a single versatile communication framework.
3Adaptability or versatility
If operators deploy only specific core network services in a service-based system, then service customization and resource efficiency improve, but network complexity in managing multiple services deteriorates
Solution Approach 1:
The patent implements self-service mechanisms where network services automatically register, discover, and configure themselves without manual intervention. Services can autonomously manage their own deployment, configuration, and interconnections, reducing the complexity of managing multiple customized services while maintaining high adaptability through automated service orchestration.

AI summary
Methods, systems, and devices for wireless communications are described. Techniques described herein provide for establishing connectivity to legacy generation wireless network via a fully service based wireless network. The fully service based wireless network may offer a core network service that is associated with a central unit of the legacy generation wireless network. A distributed unit (DU) of the fully service based wireless network may indicate to a user equipment (UE) the offered core network service. The UE may receive a service context for communications with the core network service, and the UE may transmit a service message, in accordance with the service context, to the core network service via the DU that may be forwarded to a legacy generation core network.
