MC Video Server Media Stream Termination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Mission Critical (MC) systems lack a procedure to terminate media stream transmission when no users are interested in receiving it, leading to resource wastage and preventing other users from transmitting critical data, as defined in 3GPP TS 24.581.
Innovation Solution
Implementing a new timer and counter in the MCVideo server to track active receivers and initiate a transmission end request when no receivers are active, informing the transmitter about the termination reason and allowing other users to transmit important data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If media stream transmission continues without termination procedure, then transmission stability is maintained, but network resource wastage increases and other users cannot transmit critical data
Solution Approach 1:
The server monitors receiver status and provides feedback to the transmitter. When all receivers terminate reception, the server sends a termination notification to the transmitter, creating a feedback loop that enables resource optimization based on actual reception status.
Solution Approach 2:
The server proactively monitors receiver status and initiates termination procedures before network resources are continuously wasted. The timer-based monitoring mechanism allows the server to detect when no receivers are actively receiving and trigger termination in advance, preventing ongoing resource consumption.
2Productivity
If transmission termination is implemented, then network resource efficiency improves, but system complexity increases due to new procedures and state management
Solution Approach 1:
The server's existing monitoring infrastructure is leveraged for dual purposes: current reception monitoring and future termination triggering. The timer mechanism serves multiple functions including tracking reception duration and detecting termination conditions, reducing the need for separate dedicated components.
Solution Approach 2:
The system automatically monitors receiver status and triggers termination procedures without requiring manual intervention or complex external control mechanisms. The server self-manages the termination process by detecting when all receivers have terminated and autonomously notifying the transmitter.
3Ease of operation
If no termination procedure is defined, then implementation simplicity is maintained, but transmission opportunity fairness deteriorates as other users cannot transmit important communications
Solution Approach 1:
The server monitors receiver status and provides feedback to the transmitter. When all receivers terminate reception, the server sends a termination notification to the transmitter, creating a feedback loop that enables resource optimization based on actual reception status.
Solution Approach 2:
The server proactively monitors receiver status and initiates termination procedures before network resources are continuously wasted. The timer-based monitoring mechanism allows the server to detect when no receivers are actively receiving and trigger termination in advance, preventing ongoing resource consumption.

AI summary
The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A system and a method to handle media transmission in the Mission Critical (MC) systems or MC Video system are provided. According to the system and the method, wastage of network resources can be avoided and other participants in the group can be given chance to transmit important data as maximum number of transmissions at a time in a group call are limited by network capacity. Accordingly, efficiency of the MC Video system can be improved.
