Service Quality Negotiation via Service Identifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 3GPP networks, existing methods fail to distinguish between different services using the same IP 5-tuples, resulting in the same Quality of Service (QoS) being applied to various services, which limits the ability to tailor service quality according to specific service requirements.
Innovation Solution
A method and apparatus that allow for the creation of unique Quality of Service (QoS) information associated with each service by using a service identifier within the Quality of Service creation message, enabling different QoS to be applied to different services, even when they share the same IP 5-tuples, by negotiating QoS with the 3GPP network based on service-specific information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the same QoS is applied to all services with identical IP 5-tuples, then network configuration simplicity is maintained, but service differentiation capability is lost
Solution Approach 1:
The patent segments the QoS identification approach by introducing a service identifier dimension alongside the existing IP 5-tuple. This creates a two-dimensional identification space where QoS is no longer determined solely by network layer parameters but is differentiated by combining IP 5-tuple with service-specific identifiers, enabling service differentiation while maintaining network configuration simplicity
Solution Approach 2:
The patent adds a new dimension to QoS identification by incorporating service identifiers into the QoS creation message. This dimensional extension allows the system to distinguish between different services that share the same IP 5-tuple, transforming a one-dimensional identification system into a multi-dimensional one that supports service differentiation
2Adaptability or versatility
If service-specific QoS information is created and negotiated, then service quality differentiation is improved, but negotiation complexity increases
Solution Approach 1:
The patent applies preliminary action by having the application server create and include service-specific QoS information in advance within the QoS creation message. This pre-preparation of service differentiation parameters allows the network to receive complete QoS requirements upfront, reducing the complexity of subsequent negotiation processes and enabling efficient service quality differentiation
Solution Approach 2:
The patent uses the QoS creation message as an intermediary carrier that transports service-specific differentiation information between the application server and the network. This intermediary mechanism encapsulates complex service requirements in a standardized message format, simplifying the negotiation process while maintaining service quality differentiation capabilities

AI summary
This application provides a service quality of service negotiation method and apparatus. The method includes: obtaining, by a first device, quality of service creation message sent by an application server, and creating, based on the quality of service creation message, quality of service information associated with a service. The quality of service creation message includes a service identifier and quality of service information corresponding to the service identifier. In this way, the service is associated with the quality of service, and different quality of service is used for different services.
