Floor Controller for Wireless Network Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications networks, especially in multimedia and group communications, there is a need for effective floor control mechanisms to manage limited shared radio resources, as existing technologies struggle to efficiently allocate and manage media streams between multiple endpoints.
Innovation Solution
A floor controller system that uses message sequences and protocols like SIP and RTP to manage floor ownership among endpoints, allowing authorized devices to request and assign media stream control, ensuring only authorized devices transmit media data and maintaining synchronization across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If floor control is implemented to manage limited shared radio resources, then communication reliability is improved, but device complexity increases due to additional floor request and announcement message processing
Solution Approach 1:
The patent introduces a floor controller as an intermediary component that mediates between endpoints wishing to access shared radio resources. The floor controller receives floor request messages from endpoints, processes authorization, and sends floor control announcement messages to grant or deny access. This intermediary approach centralizes the complexity of resource management while keeping endpoint devices relatively simple, resolving the contradiction by isolating complex control logic in a dedicated component.
Solution Approach 2:
The patent implements preliminary floor control checks before allowing media transmission. Endpoints must first send floor request messages and receive authorized floor control announcement messages before they can transmit media data. This preliminary action ensures that only authorized devices access the shared radio resources, improving communication reliability by preventing unauthorized transmissions and reducing interference between multiple devices.
2Adaptability or versatility
If multiple endpoints access shared radio resources simultaneously, then communication versatility is improved, but harmful interference increases among concurrent transmissions
Solution Approach 1:
The patent implements periodic floor control announcements that inform endpoints of current floor ownership status. The floor controller periodically sends floor control announcement messages to all endpoints, updating them on which endpoint currently holds the floor and is authorized to transmit. This periodic information distribution allows multiple endpoints to access the shared radio resources in a coordinated manner, improving versatility while preventing interference by ensuring only the current floor owner transmits at any given time.
Solution Approach 2:
The patent establishes a feedback mechanism where the floor controller monitors floor request messages and sends floor control announcement messages back to endpoints based on authorization decisions. This feedback loop ensures that endpoints receive real-time information about their transmission rights, allowing them to adjust their behavior accordingly. The feedback mechanism enables multiple endpoints to communicate effectively while preventing harmful interference by clearly delineating who has transmission privileges at any moment.
3Reliability
If floor control messages are processed for each endpoint, then communication reliability is improved through authorization control, but processing time increases
Solution Approach 1:
The patent designs the floor controller to handle multiple endpoints and their floor requests through a unified processing mechanism. Rather than processing each endpoint's authorization separately and sequentially, the floor controller uses a single floor control announcement message to communicate authorization status to multiple endpoints simultaneously. This universal approach maintains reliable authorization control while reducing processing time by consolidating multiple authorization operations into a single efficient process.
Data Source
AI summary
A method and system for establishing floor control in a communication session enables remote control of devices in a network and provides a status update concerning floor ownership. The method includes processing at a floor controller a floor request message received from a first endpoint, where the floor request message requests that floor ownership be provided to a second endpoint (step 305). A floor control announcement message is then transmitted from the floor controller to at least both the first endpoint and the second endpoint, where the floor control announcement message indicates that the second endpoint has floor ownership (step 315).
