Network Hub Routing for Low-Latency Service-Based Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 5G service-based core network architecture suffers from increased latency and computational overhead due to point-to-point interactions between Radio Access Network (RAN) and Core Network (CN) entities, leading to inefficient data transmission mechanisms that do not facilitate simultaneous communication with multiple Network Function (NF) nodes.
Innovation Solution
A network hub is introduced to manage control message transmissions in a 6G wireless communication system, allowing direct interaction with multiple NF nodes, reducing latency and hops by identifying and transmitting response messages to either a single or multiple NF nodes based on preconfigured information and new header structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If point-to-point interactions are used between RAN and CN entities, then direct communication is established, but control plane latency increases and the number of hops increases
Solution Approach 1:
The patent introduces a service-based interface (SBI) as an intermediary layer between RAN and CN entities. This SBI enables indirect communication through a standardized service interface, which reduces the number of hops and control plane latency while maintaining communication reliability. The service-based interface acts as a mediator that streamlines the interaction between network entities.
2Reliability
If point-to-point interactions are used between RAN and CN entities, then direct communication is established, but computational overhead increases
Solution Approach 1:
The service-based interface is designed as a universal communication mechanism that can handle multiple types of interactions between different RAN and CN entities through a standardized interface. This multi-functional approach reduces computational overhead by providing a unified communication path rather than requiring separate point-to-point connections for each entity pair.
3Stability of the object's composition
If traditional data transmission mechanisms are used, then existing architecture is maintained, but simultaneous communication with multiple NF nodes is not facilitated
Solution Approach 1:
The patent implements a dynamic service-based interface that can adaptively route communications to multiple NF nodes based on service requirements. This dynamic mechanism allows the system to maintain architectural stability while enabling flexible parallel communication with multiple network function nodes simultaneously, transforming the static point-to-point model into a dynamic multi-path communication system.

AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data Embodiments of the disclosure describe a method for data transmission in a service-based architecture by a network hub (100). The method includes receiving a message from a plurality of network function (NF) nodes (300A-300N). The method further includes sending the received message to a user equipment (UE) (200), wherein the received message is processed by the UE (200). The method includes receiving a response message from the UE (200) in response to processing the received message. The method includes identifying NF node information in the received response message. The method includes determining, based on the identified NF node information, whether the received response message is transmitted to a single NF node or multiple NF nodes of the plurality of NF nodes (300A-300N). The method includes transmitting of the received response message to the single NF node or the multiple NF nodes based on indication of the identified NF node information.
