Coreless Mobile RAN Nodes With Intermittent Core Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G and 6G network architectures face limitations in network flexibility and service options due to heavy dependency on core networks, particularly in supporting mobile RAN nodes and accommodating industry verticals, with stationary RAN nodes posing further constraints.
Innovation Solution
A coreless RAN architecture is proposed, utilizing mobile RAN nodes like UAVs that communicate independently and intermittently connect to a core network for data offloading, with mechanisms for inter-node communication and local core network functionality to provide network coverage and services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a core network is used to provide network services, then service reliability is improved, but network flexibility and adaptability deteriorate
Solution Approach 1:
The patent segments the core network functionality by introducing a coreless RAN mode where RAN nodes operate independently without requiring constant core network connection. This allows the network to be divided into autonomous RAN nodes that can function independently, thereby improving flexibility while maintaining service reliability through selective core network connectivity.
Solution Approach 2:
The patent implements dynamic network operation modes where RAN nodes can switch between core-based and coreless operations based on operational requirements. This dynamic adaptability allows the system to optimize between reliability (when core network is available) and flexibility (when coreless mode is needed), resolving the contradiction between these two parameters.
2Stability of the object's composition
If stationary RAN nodes are used, then infrastructure stability is improved, but network flexibility and service options deteriorate
Solution Approach 1:
The patent introduces mobile RAN nodes that can dynamically change their operational location and mode. These nodes can operate in coreless mode for flexibility or connect to core network for stability, allowing the system to adapt between infrastructure stability and network flexibility based on operational needs, thereby resolving the contradiction.
3Adaptability or versatility
If mobile RAN nodes operate independently without core network, then network flexibility is improved, but service reliability and data offloading capability deteriorate
Solution Approach 1:
The patent implements periodic connection to the core network where mobile RAN nodes establish connections at scheduled intervals for data offloading and service updates. This periodic action allows nodes to maintain flexibility in their mobile operations while periodically gaining access to core network services, thereby balancing network flexibility with service reliability.

AI summary
The present disclosure provides a system and a method for enabling a coreless network architecture by proposing a Radio Access Network (RAN) node for providing network coverage and services to User Equipment (UE) while not being connected or dependent on the core network. In an embodiment, the RAN node may be a mobile RAN node that forms a part of a fleet to provide network coverage and services to UEs at any geolocation as per the requirement. The disclosure also proposes mechanisms for the mobile RAN nodes to communicate amongst each other and also intermittently with the core network and data network (ISP) when available.
