Multi-Terminal Session Management for Multimedia Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies in multimedia messaging and Push to Talk systems do not allow users to receive communications on multiple terminals simultaneously, limiting the ability to use multiple devices during a session.
Innovation Solution
A method and device that create a group of terminals for a user, allowing a session to be established with multiple terminals by modifying the session invitation to include a list of terminals, enabling data distribution to all terminals in the group and managing the session history independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a session is established with only one terminal (first to respond positively), then the session establishment is simple and straightforward, but the user can only use one terminal during the session, limiting multi-terminal communication capability
Solution Approach 1:
The patent segments the session establishment process into two phases: first establishing a session with a single terminal (simple phase), then dynamically adding additional terminals to the existing session (extension phase). This allows the system to maintain simplicity for basic single-terminal communication while enabling multi-terminal capability when needed, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The patent performs preliminary actions by pre-establishing a session with one terminal before additional terminals join. The session framework is created in advance, and subsequent terminals are integrated into this pre-established structure. This preliminary session establishment simplifies the overall process while allowing flexible addition of terminals, addressing both simplicity and multi-terminal adaptability.
2Reliability
If data is retransmitted to each terminal separately, then each terminal receives complete data, but network overload and saturation occur
Solution Approach 1:
The patent merges multiple data transmission streams into a single consolidated data flow. Instead of sending separate data copies to each terminal individually, the system combines all terminal communications into one unified data stream that is processed and distributed efficiently, reducing network traffic and preventing overload while ensuring complete data delivery to all participants.
Solution Approach 2:
The patent introduces an intermediary component that acts as a central hub for data distribution. This intermediary receives data from any terminal, processes it once, and then distributes it to all other terminals in the session. This single-point processing approach ensures data completeness for all terminals while minimizing network overhead by avoiding redundant transmissions.
3Adaptability or versatility
If a single identity identifies several devices, then device group management is simplified, but the system cannot contact a given user on several of his terminals simultaneously
Solution Approach 1:
The patent implements dynamic terminal identification where the system can flexibly select which terminals to contact based on session requirements. The terminal identification is not static but adapts dynamically during the session, allowing the system to contact a given user on multiple terminals simultaneously when needed, while maintaining simplified group management through the single identity framework.
Solution Approach 2:
The patent makes the single identity framework universal by enabling it to serve multiple functions: it can identify a group of devices for simplified management, and simultaneously enable contact with multiple terminals of that user. The identity system becomes multi-functional, supporting both group-level and individual-terminal-level operations, thus resolving the contradiction between simplified management and simultaneous multi-terminal contact capability.
