Network Resource Selection via Session Control Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IP networks lack a protocol arrangement to selectively designate the most appropriate network resource for multimedia sessions, leading to costly and complex palliative solutions for clients with access to multiple resources.
Innovation Solution
A method for selecting network resources in IP networks involves sending a session control signal containing a resource identifier, allowing clients to choose the most suitable physical or virtual network for multimedia sessions based on parameters like sender identity, session nature, and stream characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clients with access to multiple network resources use palliative solutions to select appropriate resources, then service quality can be maintained, but device complexity and cost increase
Solution Approach 1:
The patent introduces a network controller as an intermediary entity that manages network resource selection. The controller receives session control signals, determines appropriate network resources based on session parameters and client capabilities, and provides guidance to clients. This mediator approach maintains service quality while reducing client-side complexity by centralizing the decision-making logic in the network infrastructure.
2Productivity
If a protocol arrangement for selective resource designation is implemented, then resource management efficiency improves, but protocol complexity increases
Solution Approach 1:
The patent implements preliminary action by having the network controller pre-determine and indicate appropriate network resources to clients before actual multimedia session establishment. The controller analyzes session parameters, client capabilities, and network conditions in advance, then provides resource guidance that clients can directly use when initiating sessions. This approach improves resource management efficiency while minimizing protocol complexity by preparing decisions beforehand rather than making them in real-time during session establishment.
3Adaptability or versatility
If clients autonomously select network resources without guidance, then device independence is maintained, but service quality and QoS assurance deteriorate
Solution Approach 1:
The patent implements a dynamic resource selection mechanism where the network controller adapts its resource recommendations based on real-time session parameters, client capabilities, and network conditions. The system maintains client independence by providing guidance rather than mandatory assignments, allowing clients to make informed decisions while ensuring QoS through controller-based resource assessment. The dynamic nature allows the system to adjust to changing conditions while preserving client autonomy.

AI summary
The invention relates to a method for selecting a network resource, in which a so-called monitored device (10, 11) connected to an IP network (20) can further access at least one other physical and/or virtual telecommunication network. According to the invention, after a step in which a request is transmitted or forwarded by the monitored device (10, 11) or sent to said monitored device (10, 11), the monitored device (10, 11) receives a session monitoring signal including a resource identifier representative of the physical or virtual network that the monitored device (10, 11) can or must use to fulfill said request.
