5GMS Application Provider for Uplink-Downlink Streaming Session Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G media streaming architectures do not provide a method to set up sessions for streaming content from one user to other users by connecting uplink and downlink streaming, as defined by the 3rd Generation Partnership Project (3GPP) TS26.512 for uplink streaming.
Innovation Solution
A method involving a 5GMS application provider that transmits requests to create content hosting configuration templates for both downlink and uplink AFs, including protocol information, to establish connections for streaming content between users, utilizing specific interfaces and APIs within the 5GMS architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing streaming architecture is used for uplink streaming, then content can be streamed from device to external service provider, but there is no capability to set up sessions for streaming content from one user to other users by connecting uplink and downlink streaming
Solution Approach 1:
The patent introduces an application provider as an intermediary entity that mediates between uplink and downlink AFs to establish peer-to-peer streaming sessions. The application provider sends requests to both uplink and downlink AFs to create content hosting configuration templates, enabling indirect connection setup between users without requiring direct peer-to-peer protocol implementation in the core network architecture.
Solution Approach 2:
The patent segments the streaming session setup process into separate uplink and downlink configuration operations. Instead of attempting to establish a complete peer-to-peer session through a single monolithic procedure, the system independently configures uplink content hosting and downlink content hosting templates, then connects them through the application provider's coordination.
2Adaptability or versatility
If new session setup procedures are implemented to enable peer-to-peer streaming, then adaptability of the streaming architecture is improved, but the complexity of the system increases
Solution Approach 1:
The application provider serves as a mediator that abstracts the complexity of peer-to-peer session setup from the core network elements. By introducing this intermediary layer, the patent enables versatile peer-to-peer streaming functionality without requiring complex modifications to the existing AF architecture, as the application provider handles the coordination logic externally.
Solution Approach 2:
The patent implements a universal session setup mechanism that can handle both traditional uplink streaming and new peer-to-peer streaming scenarios through the same application provider interface. The content hosting configuration templates are designed to be multi-functional, supporting different streaming modes without requiring separate specialized procedures.

AI summary
A method, device, and non-transitory computer-readable storage medium are provided. The method includes transmitting, with a 5th generation media streaming (5GMS) application provider to a 5GMS downlink application function (AF), a first request to create a first content hosting configuration template, receiving, at the 5GMS application provider from the 5GMS downlink AF, the first content hosting configuration template, transmitting, with the 5GMS application provider to a 5GMS uplink AF, a second request to create a second content hosting configuration template, the second request including protocol information, and receiving, at the 5GMS application provider from the 5GMS uplink AF, an acknowledgement that the second content hosting configuration template is created.
