WebRTC QoS Improvement via Network-Side Parameter Acquisition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current WebRTC QoS improvement methods burden user equipment with the task of collecting and managing IP addresses and service port numbers for audio and video communications, making the process difficult and inefficient.
Innovation Solution
A network-side solution where the WebRTC server and QoS decision network element collaborate to acquire and manage IP addresses and service port numbers, reducing the burden on user equipment by establishing a correspondence between these details and user identities, allowing for efficient QoS improvement requests to be sent to the PCRF.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment collects IP addresses and service port numbers of both parties to send QoS improvement requests, then QoS improvement can be achieved, but burden on user equipment increases and ease of operation deteriorates
Solution Approach 1:
The patent introduces a network element (PGW or PCRF) as an intermediary to collect and manage IP addresses and service port numbers. Instead of user equipment directly collecting this information, the network element automatically obtains these parameters during the webRTC communication setup and provides them to the QoS decision network element when a QoS improvement request is received. This intermediary approach maintains QoS improvement effectiveness while eliminating the operational burden from user equipment.
Solution Approach 2:
The network element performs self-service by automatically collecting and managing the communication parameters (IP addresses and service port numbers) without requiring user equipment intervention. The network element monitors the webRTC communication setup, extracts the necessary parameters, and maintains them ready for QoS improvement requests, thereby freeing user equipment from this task while ensuring accurate parameter availability.
2Reliability
If user equipment manages communication parameters manually, then QoS control is possible, but device complexity increases
Solution Approach 1:
The network element serves as an intermediary that centralizes the management of communication parameters. It automatically tracks IP addresses and service port numbers for both parties in the webRTC communication, maintaining this information in association with user identities. This eliminates the need for user equipment to implement complex parameter management logic, reducing device complexity while preserving QoS control capability through the network element.
Solution Approach 2:
The patent extracts the parameter management function from user equipment and relocates it to the network element. By separating this complex management task from the end devices, the system reduces user equipment complexity while maintaining QoS control capability through the dedicated network element that handles parameter collection, storage, and retrieval.
3Ease of operation
If the network side acquires and manages communication parameters, then ease of operation improves, but device complexity on network side increases
Solution Approach 1:
The network element leverages its existing multi-functional role in the network infrastructure to perform parameter management. As a PGW or PCRF, it already handles user authentication, session management, and QoS policy enforcement. By integrating parameter collection and management into these existing functions, the system improves ease of operation without requiring a completely new complex device, as the network element utilizes its inherent multi-functionality.
Solution Approach 2:
The network element performs parameter management as a self-service function within its existing operational framework. It automatically collects parameters during normal communication setup, associates them with user identities, and makes them available when needed for QoS improvement requests. This self-service approach allows the network element to handle the increased functional responsibility without requiring external management systems, balancing improved ease of operation with controlled network side complexity.
