QoS Provisioning via Interface Server Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication systems fail to provide services with desired Quality of Service (QoS) classes to mobile stations, limiting users to preset QoS classes supported by the network, which restricts the quality of services such as IPTV, music/video streaming, and other content services.
Innovation Solution
A system and method where a service server requests and verifies QoS information through an interface server, allowing mobile stations to receive services with requested QoS classes by identifying supported QoS classes over the access network and notifying users of available options, enabling selection of desired QoS classes for enhanced service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the communication network provides only preset QoS classes, then the network complexity is reduced and ease of operation is improved, but the adaptability of service quality to user requirements deteriorates
Solution Approach 1:
An interface server is introduced as an intermediary between the service server and the access network. This interface server handles QoS information requests and responses, mediating between user QoS requirements and network capabilities. The service server requests QoS information through the interface server, which then communicates with the access network to determine supported QoS classes, thereby resolving the contradiction by adding a coordinating layer that maintains network simplicity while enabling flexible QoS selection.
2Adaptability or versatility
If the service server allows selection of desired QoS classes, then the adaptability to user needs is improved, but the device complexity and information processing requirements increase
Solution Approach 1:
The service server autonomously manages QoS class selection by initiating requests to the interface server and processing the responses. The system performs self-service by automatically determining which QoS classes are supported by the access network and selecting appropriate classes without requiring manual intervention or complex user configuration, thereby reducing the perceived complexity for users while maintaining high adaptability.
Solution Approach 2:
The interface server provides feedback to the service server regarding which QoS classes are supported by the access network. This feedback mechanism enables the service server to make informed decisions about QoS class selection based on real-time network capabilities, resolving the contradiction by implementing a simple feedback loop that guides QoS selection without requiring complex decision-making logic.

AI summary
A system and method for providing a service in a communication system are provided, in which upon receipt of a request for provisioning of the service with a requested QoS class from an MS, a service server transmits a QoS information request message to an interface server and, upon receipt of a QoS information response message for the QoS information request message from the interface server, the service server provides the service with the requested QoS class to the MS.
