Push-to-talk Virtual User Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing push-to-talk (PTT) communication systems only support content delivery in push mode, limiting the variety of services that can be provided to users, as they do not allow users to request specific content, thereby not supporting pull mode or content providing modes.
Innovation Solution
A method and system that associate a virtual user with content, establishing a push-to-talk session to deliver content from the virtual user to actual users, enabling content delivery in push, pull, and content providing modes by managing talk grants and session types, allowing users to request specific content and contribute content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If push-to-talk systems use traditional half-duplex voice communication mode, then users can communicate in real-time with simple operation, but the system cannot support content delivery services in pull mode or content providing mode
Solution Approach 1:
The patent introduces a virtual user as an intermediary entity that mediates between the content server and actual users. The virtual user acts as a placeholder that can be associated with content, allowing the system to manage content delivery sessions without requiring actual users to directly initiate or manage complex session states. This intermediary enables pull mode and content providing mode by allowing the virtual user to hold content references that can be delivered to requesting users.
Solution Approach 2:
The patent enhances the universality of the push-to-talk system by enabling it to perform multiple content delivery modes (push mode, pull mode, and content providing mode) using the same underlying session management infrastructure. By allowing virtual users to be associated with content and by enabling flexible talk grant allocation, the system becomes multi-functional, supporting diverse service types without requiring separate systems for each mode.
2Adaptability or versatility
If the system allows users to request specific content (pull mode), then service diversity increases, but the talk grant management becomes more complex
Solution Approach 1:
In pull mode, the system enables users to self-initiate content requests by selecting content associated with virtual users. The talk grant management becomes more automated, where the system automatically handles the allocation and release of talk grants based on session establishment and termination, reducing the manual burden on users while maintaining service diversity.
3Adaptability or versatility
If multiple content delivery modes are supported, then user interaction diversity enhances, but the session establishment and management becomes more complicated
Solution Approach 1:
The patent inverts the traditional approach by allowing virtual users to be the initiators of content delivery sessions rather than actual users. The content server associates content with virtual users, and these virtual users can then initiate sessions with actual users. This inversion simplifies session management because the virtual users serve as standardized, predictable entities that the system can manage centrally, reducing the complexity of handling diverse user-initiated sessions.

AI summary
A method of providing a content delivery service to an actual user of a communication system supporting push-to-talk. The content delivery service includes delivering a content to the actual user, wherein the method includes associating a virtual user to said content; establishing a push-to-talk session involving the actual user and the virtual user; and delivering the content from the virtual user to the actual user through the established push-to-talk session.
