Push-to-Talk Floor Control for Coordinated Multi-Media Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing push-to-talk services, such as PoC 1, lack effective coordination of floor control for multiple media types during sessions, leading to issues like uncoordinated media access and discarding of media bursts from other clients, which is undesirable when sending different types of content like voice and video simultaneously.
Innovation Solution
A method and apparatus for sending a single floor request message that coordinates multiple media types, allowing or denying requests based on inter-dependencies and designations, enabling simultaneous or sequential access to media types, and specifying which terminal provides the media, ensuring coordinated access to multiple media types in a push-to-talk session.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate floor control mechanisms are used for different media types, then each media type can be controlled independently, but coordination between media types deteriorates leading to uncoordinated media access and discarding of media bursts
Solution Approach 1:
The patent combines multiple floor control requests for different media types (voice, video, data) into a single unified floor control mechanism. The floor control entity receives one request that encompasses all media types, evaluates them together considering their inter-dependencies, and grants or denies floor access in a coordinated manner, preventing the discarding of media bursts from other clients.
2Productivity
If floor control grants access to one media type, then that media can be transmitted, but other media types from the same or different clients may be discarded due to lack of coordination
Solution Approach 1:
The patent implements preliminary evaluation of all media type requests before granting floor access. The floor control entity assesses the inter-dependencies and compatibility of multiple media types in advance, determining the optimal combination to grant together. This preliminary coordination ensures that no media bursts are discarded due to lack of coordination, as all decisions are made holistically before transmission begins.
3Ease of operation
If multiple floor control mechanisms operate independently, then each can optimize its media type, but overall session integrity deteriorates
Solution Approach 1:
The patent creates a universal floor control mechanism that handles multiple media types (voice, video, data) through a single coordinated process. This multi-functional floor control entity evaluates and manages all media types together, considering their specific requirements and inter-dependencies, while maintaining overall session integrity. The unified approach ensures that no single media type optimization compromises the stability of the entire session.

AI summary
A method and apparatus for processing a floor request in a push to talk type service in which a floor is required for a first terminal to distribute media to a second terminal. The first terminal sends a floor request message to a PoC Server. The message relates to at least two different types of media content and indicates how and to what extent the granting or denial of the different media types interrelate. The message may indicate, for example, that if a first media type is denied, the others should be denied; or that the granting or denial of the first media type should not affect the other media types. The message may also indicate other conditions and relationships. The PoC Server processes the request based on the indicated interrelationships and/or conditions, and grants or denies each media type.
