5G Media Streaming QoS Binding for Service Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 5G media streaming system lacks fine-tuned control over media stream transmission, unable to distinguish between different types of media stream services with the same IP address and port number, and fails to consider continuity requirements during interaction between network devices and application servers.
Innovation Solution
Implementing service differentiators and service stream type identifiers to differentiate media stream services, enabling finer QoS control, and negotiating continuity features with the core network to ensure appropriate service continuity during user terminal movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the existing 5GMS system uses standard IP address and port number for media stream transmission, then the system architecture remains simple, but the network side device cannot distinguish between different types of media stream services
Solution Approach 1:
The patent introduces service differentiators as an intermediary element that carries service type information within existing IP packets. This mediator enables the network side device to distinguish different media stream services without fundamentally changing the IP addressing structure, thus resolving the contradiction between differentiation capability and system complexity
Solution Approach 2:
The patent modifies the existing packet structure by adding service differentiator parameters to identify different media stream services. This parameter change approach allows the network to recognize and handle different service types (e.g., video calling, streaming) using the same IP address and port, improving measurement precision without requiring complete system redesign
2Reliability
If the existing 5GMS system does not negotiate continuity requirements, then the interaction process remains simple, but service continuity cannot be ensured during user terminal movement
Solution Approach 1:
The patent implements preliminary negotiation of continuity requirements between the network side device and application server before media stream transmission begins. By establishing continuity features (such as SSC modes) in advance, the system ensures service continuity during user terminal movement without requiring complex real-time negotiations, thus improving reliability while controlling interaction complexity
Solution Approach 2:
The patent establishes a feedback mechanism where the network side device and application server exchange continuity requirement information and negotiate appropriate continuity features. This feedback loop enables the system to adapt to different service continuity needs (e.g., high mobility vs. stationary services) while maintaining a relatively simple interaction framework

AI summary
Embodiments of the present application provide a method for controlling media streaming service transmission, a user terminal for controlling media streaming service transmission, a network node in a data network, a network node in a core network, a system for controlling media streaming service transmission, a non-volatile computer-readable storage medium, and an electronic device. The method for controlling media streaming service transmission comprises: from a network node in a data network, receiving policy template information for controlling media streaming service transmission and a service distinguisher corresponding to said policy template information, said service distinguisher being used for distinguishing media streaming services of different service types among the media streaming services; on the basis of said policy template information and said service distinguisher, determining the service distinguisher of a media streaming service to be initiated; determining whether there is a protocol data unit session capable of carrying said media streaming service to be initiated, said protocol data unit session comprising a quality of service flow corresponding to the service distinguisher of the media streaming service to be initiated; if said protocol data unit session is present, then binding the media streaming service to be initiated to a quality of service flow in the protocol data unit session; if said protocol data unit session is not present, then establishing a protocol data unit session comprising a quality of service flow corresponding to the service distinguisher of the media streaming service to be initiated.
