5G Uplink Streaming Call Flows for External Network Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G media streaming architectures lack defined call flows for various collaboration scenarios in uplink streaming, particularly in non-trusted data networks, limiting the flexibility and efficiency of media content delivery.
Innovation Solution
The proposed solution involves defining media architectures and call flows for uplink streaming in 5G networks, including collaboration scenarios where 5GMSu Application Providers can deploy 5GMSu AS in both trusted and external data networks, utilizing proprietary interfaces and functions to manage media streaming sessions and policies, ensuring compatibility and flexibility across different network environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 5GMSu AS is deployed only in trusted data networks, then security and reliability are improved, but adaptability and versatility are worsened
Solution Approach 1:
The patent segments the 5GMSu AS deployment into multiple independent scenarios: trusted data network deployment and external data network deployment. Each scenario has its own specific call flow and security requirements, allowing the system to adapt to different deployment environments while maintaining security through scenario-specific configurations.
Solution Approach 2:
The patent introduces dynamic deployment options where the 5GMSu AS can be flexibly deployed in either trusted or external data networks based on operator requirements. The system dynamically adapts its behavior and security measures according to the deployment scenario, enabling both security and versatility.
2Adaptability or versatility
If standardized interfaces are used for all deployment scenarios, then interoperability is improved, but adaptability to specific scenarios is worsened
Solution Approach 1:
The patent defines a universal 5GMSu architecture that can function in multiple deployment scenarios (trusted data network, external data network, home network, visited network). The same core architecture serves multiple purposes through scenario-specific configurations and call flows, reducing the need for separate standardized interfaces for each scenario.
Solution Approach 2:
The patent applies local quality by defining scenario-specific call flows and interface behaviors tailored to each deployment environment. Each scenario has optimized interfaces and procedures suited to its specific requirements, while still integrating into the overall universal architecture.
3Adaptability or versatility
If uplink streaming is supported in external data networks, then adaptability and coverage are improved, but security risks and harmful factors are worsened
Solution Approach 1:
The patent introduces the 5GMSu AF (Application Function) as an intermediary between the 5GMSu AS and external data networks. The AF performs critical functions including service authorization, authentication, and security policy enforcement, acting as a trusted mediator that enables external network deployment while mitigating security risks through layered security controls.
Solution Approach 2:
The patent implements preliminary security actions through authorization and authentication procedures that occur before uplink streaming begins in external data networks. The 5GMSu AF pre-validates service requests, checks authorization policies, and establishes security parameters in advance, preventing unauthorized access and reducing security risks before they can manifest.

AI summary
Systems, devices, and methods for media processing and streaming, including transmitting, by a 5G media streaming uplink (5GMSu) application provider (AP), a request to create a provisioning session for 5GMSu streaming using a 5GMS system; receiving, by the 5GMSu AP, an acknowledgement corresponding to the provisioning session; and performing, by the 5GMSu AP, a 5GMSu egest operation corresponding to the 5GMSu streaming, wherein the 5GMSu AP is included in an external data network (DN) which is external to the 5GMS system.
