PoC Floor Control Scheme Transfer via Session Request
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional PoC technology lacks a method for applying a specified floor control scheme to randomly-created PoC sessions, such as one-to-one or ad-hoc sessions, and does not provide a detailed method for transferring a floor control scheme to corresponding clients in pre-arranged groups.
Innovation Solution
A method and system for transferring and applying a specific floor control scheme during PoC session establishment through a floor control scheme transmission or negotiation procedure, involving a PoC client acquiring a floor control scheme ID, sending a session participation request message to a PoC server, and the server applying the scheme to participating clients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional PoC technology is used without floor control scheme transfer, then PoC sessions can be established quickly, but floor control schemes cannot be applied to randomly-created sessions or pre-arranged groups
Solution Approach 1:
The patent applies preliminary action by having the PoC client acquire the floor control scheme ID and include it in the session participation request message before the session is actually established. This allows the floor control scheme to be predetermined and transferred in advance, enabling its application to both randomly-created and pre-arranged sessions without adding complexity to the session establishment process.
2Reliability
If floor control scheme details are transferred to all participating clients, then compatible clients can be ensured, but additional signaling overhead is introduced
Solution Approach 1:
The patent extracts only the essential floor control scheme ID from the complete floor control scheme details and transfers this condensed identifier to participating clients through the session participation request message. The PoC server then uses this ID to retrieve and apply the corresponding floor control scheme. This extraction approach ensures client compatibility while minimizing signaling overhead by transmitting only the necessary identifier rather than the entire scheme definition.

AI summary
Disclosed is a method and system for transferring and applying a floor control scheme when a Push-To-Talk (PTT) over Cellular (PoC) session is established between PoC clients supporting various types of floor control schemes (e.g., media burst control schemes). According the method and system, when a PoC client providing Open Mobile Alliance PoC multimedia communication service supports a plurality of floor control schemes and there is no floor control scheme appointed to be supported in a session, a floor control scheme requested by a PoC session establisher is transferred through a PoC session establishment procedure and is applied to the session.
