5G and ATSC 3.0 Integrated Core Network for Multimedia Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G mobile communication systems lack a scalable and cost-efficient Point-to-Multipoint (P2M) solution for transmitting high-quality multimedia content to multiple users, as they are designed for point-to-point (P2P) data transmission, which is inefficient for mass media distribution.
Innovation Solution
The integration of ATSC 3.0 terrestrial networks into 5G architecture using Access Traffic Steering, Switching, and Splitting (ATSSS) methods, allowing for the initialization of ATSC 3.0 sessions and the activation of control and user planes to transmit multimedia content over ATSC 3.0 terrestrial networks, enabling efficient P2M transmission.

Engineering Contradiction Analysis
1Productivity
If 5G mobile communication systems use point-to-point data transmission infrastructure, then individual user connectivity is maintained, but scalable and cost-efficient Point-to-Multipoint transmission for high-quality multimedia content to multiple users cannot be achieved
Solution Approach 1:
The patent merges 5G mobile network infrastructure with ATSC 3.0 terrestrial broadcast infrastructure to create an integrated network that supports both point-to-point and point-to-multipoint transmission modes, enabling efficient multimedia content delivery to multiple users simultaneously
Solution Approach 2:
The integrated core network is designed to perform multiple functions by supporting both 5G P2P communication and ATSC 3.0 P2M broadcast transmission through a unified architecture, allowing the network to adapt to different transmission requirements without requiring separate dedicated infrastructure
2Adaptability or versatility
If ATSC 3.0 broadcast downlink access is used, then unlimited simultaneous users can consume the same content, but integration with 5G control plane requires additional session initialization and activation procedures
Solution Approach 1:
The ATSC 3.0 gateway functionality is segmented into separate control plane and user plane functions, with the control plane handling session management and the user plane handling actual content transmission, allowing for modular integration with 5G control plane
Solution Approach 2:
The ATSC 3.0 gateway acts as an intermediary between the 5G core network and the ATSC 3.0 terrestrial broadcast network, facilitating controlled integration by initializing sessions and activating user planes through standardized procedures
3Productivity
If Access Traffic Steering, Switching and Splitting is performed to enable P2M transmission, then multimedia content can be delivered over ATSC 3.0 terrestrial network, but additional control procedures for session initialization and activation are required
Solution Approach 1:
The control plane performs preliminary actions by pre-establishing session parameters and activation configurations before actual content transmission begins, allowing for faster session setup and reducing the time required to activate P2M transmission

AI summary
Disclosed herein is an integrated core network of 5G and ATSC 3.0. The integrated core network of 5G and ATSC 3.0 includes multiple control plane entities and a user plane entity, and further includes an ATSC 3.0 gateway, thereby enabling multimedia content transmitted from the ATSC 3.0 gateway to the user plane entity under the control of the control entity to be delivered to user equipment over an ATSC 3.0 terrestrial network. The ATSC 3.0 gateway may include an ATSC 3.0 Control Plane Gateway (CP-GW) connected between the user plane entity and the multiple control plane entities and an ATSC 3.0 User Plane Gateway (UP-GW) connected to the user plane entity.
