Telecommunication Service Parameter Matching for QoS Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing service composition technologies in telecommunication networks face challenges in dynamically selecting and invoking constituent services that meet specific user requirements and quality of service (QoS) parameters, especially as user demands and context change.
Innovation Solution
A method is proposed where a first group of parameters associated with a composite service is compared to a second group of parameters associated with a constituent service, determining matching parameters to set requirements for the constituent service, which are then used to invoke the service, ensuring optimal QoS and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If constituent services are selected based on generic service descriptions, then service composition flexibility is improved, but QoS matching precision deteriorates
Solution Approach 1:
The patent transforms generic service descriptions into structured parameter sets that explicitly represent QoS requirements. By changing the representation from textual descriptions to parameter tuples (e.g., bandwidth, latency, jitter), the system achieves both flexibility in service composition and precision in QoS matching through systematic parameter comparison and selection algorithms.
2Loss of time
If services are selected based on context alone, then response time is improved, but service functionality accuracy deteriorates
Solution Approach 1:
The patent performs preliminary analysis of service descriptions and QoS requirements before actual service selection. By pre-processing and structuring service parameters in advance, the system enables rapid matching during runtime while maintaining accuracy through the pre-established parameter frameworks, thus reducing response time without sacrificing functionality accuracy.
3Adaptability or versatility
If dynamic service selection is implemented, then adaptability to changing needs is improved, but selection complexity increases
Solution Approach 1:
The patent segments the service selection process into distinct manageable stages: service description parsing, QoS parameter extraction, parameter matching, and service invocation. This segmentation reduces overall selection complexity by breaking down the dynamic selection task into simpler, sequential operations that can be handled systematically despite changing user needs.

AI summary
A method is described for invoking a constituent service in a telecommunication network. The constituent service is associated to a composite service. A first group of parameters is determined which is associated with the composite service. A second group of parameters is determined which is associated with the constituent service. The first and the second group of parameters are compared. If there are matching parameters (212) in the first and the second group requirements are determined for the constituent service based on the matching parameters in the first and the second group. The constituent service (216) is invoked according to these requirements. An application server is also described.
