Dynamic Media Proxy for Interoperability and Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in interoperability between different technologies and standards, leading to inefficient collaboration among security and safety personnel, as endpoints not conforming to expected behavioral characteristics may disrupt talk group features and pose security risks.
Innovation Solution
A dynamic media proxy system that negotiates capabilities and resources to connect non-compatible communication devices, assesses security risks, and optimizes system resource utilization by employing a proxy for endpoints that do not adhere to transmission rules, ensuring secure and efficient communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a static proxy is employed for all endpoints, then system security and resource management are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent implements a dynamic proxy assignment mechanism where the decision to assign a proxy to an endpoint is not fixed but changes based on real-time capability assessments and resource conditions. The system evaluates endpoint capabilities, resource availability, and transmission rule compliance dynamically, allowing the proxy configuration to adapt automatically rather than being statically predetermined for all endpoints.
Solution Approach 2:
The system changes the parameter of proxy assignment from a static binary state (always assigned or never assigned) to a dynamic state that varies based on multiple parameters including endpoint capability metrics, resource availability thresholds, and compliance status. This allows the same endpoint to have different proxy assignments at different times based on changing system conditions.
2Adaptability or versatility
If capability negotiation is implemented for all endpoints, then interoperability is improved, but system resource consumption and device complexity increase
Solution Approach 1:
The patent applies partial capability negotiation by selectively engaging in detailed capability assessment only with endpoints that require it based on initial screening criteria. Not all endpoints undergo the full capability negotiation process; instead, the system performs targeted assessments on endpoints where interoperability issues are detected or suspected, reducing overall system resource consumption while maintaining necessary interoperability.
Solution Approach 2:
The system introduces an intermediary assessment layer between endpoints and the full capability negotiation process. This intermediary performs initial capability screening and only triggers detailed negotiation when necessary, acting as a buffer that reduces the frequency and scope of full capability assessments while still enabling interoperability when needed.
3Measurement precision
If manual intervention is used for cross-network communication, then communication accuracy is improved, but productivity and loss of time worsen
Solution Approach 1:
The patent implements self-service capability assessment and proxy assignment where the system automatically evaluates endpoint capabilities, determines compliance with transmission rules, and assigns proxies without requiring manual human intervention. The endpoint devices themselves participate in the assessment process by providing capability information, and the system autonomously makes routing decisions based on assessed capabilities and resource conditions.
Solution Approach 2:
The system incorporates feedback loops where endpoint capability information is continuously collected, assessed, and used to adjust proxy assignments and routing decisions in real-time. This feedback mechanism enables automatic adaptation to changing conditions while maintaining communication accuracy through continuous monitoring and adjustment rather than static manual configuration.
Data Source
AI summary
A system and methodology to facilitate communication between non-compatible communication devices by utilization of a dynamic media proxy is provided. Information associated with an endpoint, such as, media capabilities, identity and system resource information is collected. Media proxy'ing is performed as part of capability negotiation. A dynamic media proxy is employed based on an analysis of the collected information. An analysis component can identify an endpoint that does not adhere to specific rules of transmission and can dynamically connect such an endpoint to a VTG (virtual talk group) via a proxy to prevent the endpoint from transmitting media into an active VTG that already has multiple talkers streaming media. Additionally, the location where media processing can occur can be dynamically determined based on the available system resources.
