5G RTC Edge Provisioning for Network-Driven WebRTC Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 3GPP TS26.506 specification lacks a method for communication workflow to dedicate edge servers for 5G real-time communication (RTC) sessions, necessitating a need for a network-driven management approach.
Innovation Solution
A method and apparatus for network-driven management of 5G Real-time Media Communication (5G RTC) involving the creation of a provisioning session between an edge-enabled RTC application function (AF) and an edge-enabled RTC application provider (AP), determining service access information, and initiating media streaming over a 5G network based on eligibility for edge processing resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If edge servers are used in 5G RTC sessions, then media streaming performance is improved, but the complexity of network management increases due to lack of dedicated communication workflow
Solution Approach 1:
The patent segments the edge server management into distinct functional components: RTC provisioning session creation between AF and AP, service access information determination, and eligibility verification for edge processing resources. This segmentation transforms the complex monolithic management process into manageable modular steps, reducing overall system complexity while maintaining improved media streaming performance
Solution Approach 2:
The patent implements preliminary actions by creating RTC provisioning sessions and determining service access information before actual media streaming begins. The network determines eligibility for edge processing resources in advance, so that when media streaming starts, the edge servers are already configured and ready, simplifying real-time management while ensuring optimal performance
2Adaptability or versatility
If edge processing resources are allocated for RTC sessions, then resource utilization is improved, but the difficulty of determining service access information increases
Solution Approach 1:
The patent implements feedback mechanisms where the network continuously monitors RTC session parameters, user equipment capabilities, and network conditions to determine service access information. The system receives feedback about session eligibility and adjusts edge processing resource allocation accordingly, enabling high resource utilization while managing the complexity of access information determination through iterative optimization
Solution Approach 2:
The patent utilizes parameter changes by evaluating multiple variables including user equipment capabilities, session type, network conditions, and service requirements to determine service access information. By systematically analyzing and weighting different parameters, the system can efficiently assess eligibility for edge processing resources without overwhelming complexity, achieving both high adaptability and manageable determination difficulty

AI summary
A method, apparatus, and non-transitory storage medium for network driven management of 5G Real-time Media Communication (5G RTC) for edge processing may be provided. The method may include creating a real-time communication (RTC) provisioning session by a RTC application provider (AP) with a RTC application function (AF) and provisioning one or more RTC features associated with the RTC provisioning session by the RTC AP. The method may also include receiving a notification of a WebRTC session starting over a 5G network, then determining whether the WebRTC session is eligible for requesting edge resources; and starting media streaming over the 5G network.
