Floor Control Profile Integration in Communication Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems require separate message exchanges for call setup and floor control, leading to undesired delays in establishing multimedia sessions due to the need for simultaneous completion of both processes.
Innovation Solution
A method and apparatus that dynamically assign a floor control profile to each session at call initiation, associating floor control parameters with the session and media streams, and reserve communication resources only for endpoints that will source media, thereby eliminating the need for separate message sequences and minimizing call setup times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate protocols are used for call control and floor control, then each protocol can be optimized independently, but call setup time increases due to requiring two separate message exchanges
Solution Approach 1:
The patent combines call control and floor control into a single integrated protocol framework. Floor control parameters are embedded within the call setup messaging sequence, allowing both call establishment and floor control configuration to occur simultaneously through one message exchange rather than requiring separate protocol interactions.
Solution Approach 2:
Floor control parameters are predetermined and pre-configured in the system. During call setup, these pre-prepared parameters are automatically included in the messaging sequence, eliminating the need for separate floor control negotiation and reducing overall setup time while maintaining protocol optimization benefits.
2Reliability
If communication resources are reserved for all endpoints in a session, then resource availability is ensured, but resource utilization efficiency decreases when not all endpoints source media
Solution Approach 1:
The patent applies differentiated resource allocation based on individual endpoint characteristics. Instead of uniform resource reservation for all endpoints, the system identifies which endpoints will actually source media and reserves resources only for those specific endpoints, optimizing resource distribution according to local needs rather than applying a blanket approach.
Solution Approach 2:
The system reserves communication resources partially - only for endpoints that will source media - rather than reserving for all endpoints. This selective partial reservation maintains sufficient resource availability for active media sources while avoiding unnecessary resource consumption by endpoints that will not transmit media.

AI summary
Methods for enabling floor control are performed in an endpoint terminal (140, 142, 146) and a session controller (106). The session controller: receives (410) a message requesting a session that includes an SDP packet with a requested floor control profile having a requested set of floor control parameters or a requested list of potential floor owners; accepts (410) the session; determines (420) a final floor control profile having a final set of floor control parameters and a final list of potential floor owners; and communicates at least a portion of the floor control profile within a system (100). The endpoint terminal: communicates a message requesting a session that includes an SDP packet with a requested floor control profile; and receives a message having an SDP packet with a final floor control parameter. The final floor control profile may be the same as or different from the requested floor control profile.
