Dynamic Satellite Link Management via Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multicast communication systems incur significant operational costs due to pre-configured, always-on satellite links that reserve bandwidth even when not needed, as they do not efficiently manage links based on user presence and bandwidth requirements.
Innovation Solution
A system that dynamically establishes and tears down satellite links based on user presence and bandwidth needs, using virtual talk group presence managers and dynamic trunking elements to bring up links only when active users are detected, optimizing bandwidth allocation and reducing unnecessary costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-configured satellite links are always on to reserve bandwidth, then link availability is improved, but operational costs increase
Solution Approach 1:
The system dynamically adjusts satellite link status based on real-time presence information. Links are activated when users are present and deactivated when no users are present, transitioning the system from a static always-on state to a dynamic on-demand state. This resolves the contradiction by maintaining link availability only when needed while reducing operational costs during idle periods.
Solution Approach 2:
The system changes the operational parameter of satellite links from a fixed state to a variable state based on presence detection. When presence information indicates active users, links are brought up; when no presence is detected, links are torn down. This parameter change allows the system to optimize between availability and cost by adjusting link status according to actual usage requirements.
2Speed
If satellite links are always on to ensure immediate communication, then communication speed is improved, but bandwidth waste increases
Solution Approach 1:
The system implements periodic monitoring of presence information and adjusts link status accordingly. Rather than maintaining continuous links, the system periodically checks for active users and activates or deactivates links based on current presence status. This periodic action ensures communication readiness when users are present while avoiding bandwidth waste during idle periods.
Solution Approach 2:
The system makes bandwidth allocation dynamic by tying it to real-time presence information. Bandwidth is allocated to satellite links only when presence data indicates active users require communication, and released when no users are present. This dynamic approach eliminates bandwidth waste while maintaining communication speed when needed.
3Device complexity
If manual link management is used, then system complexity is reduced, but productivity decreases
Solution Approach 1:
The system implements self-service automation where presence information automatically triggers link activation or deactivation without manual intervention. The automated link manager monitors presence data and independently manages satellite link status, eliminating the need for manual link management while significantly improving productivity through automated, real-time adjustments.
Solution Approach 2:
The system uses feedback from presence information to automatically control link status. Presence data serves as input feedback that triggers automated link management actions - links are activated when presence indicates users are available and deactivated when no presence is detected. This feedback loop enables automated link management that improves productivity without increasing system complexity.

AI summary
A method is provided in one example implementation and the method includes interacting, via a first communication resource manager located in a first domain, with a second communication resource manager located in a second domain. The method further includes determining whether to establish a link for multicasting between users in the first domain and users in the second domain, and the link between the domains is established based on presence data of at least one user in the first domain and at least one user in the second domain.
