Mobile Terminal Speaking Turn Management via QoS Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing speaking in meetings using personal mobile terminals face issues such as high communication costs during international conferences, network congestion affecting audio quality, and difficulty in locating speakers, especially when using voice over IP technologies.
Innovation Solution
Implementing a method that restricts access to online services within a local area network to prioritize communication quality by imposing bit rate limits on terminals accessing the network, allowing for guaranteed minimum bit rates during voice over IP communications, and associating connection requests with location and reason data to facilitate speaker identification and queue management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If voice over IP communication is implemented using WiFi access point for free communication, then communication costs are reduced, but network congestion occurs and audio quality deteriorates
Solution Approach 1:
The patent segments network traffic into different priority levels: voice communication traffic is given high priority while other data traffic is deprioritized. This is achieved through traffic classification and quality of service (QoS) mechanisms that ensure voice packets receive sufficient bandwidth and low latency, preventing audio quality deterioration even when multiple devices are connected to the WiFi network.
Solution Approach 2:
The system dynamically adjusts network parameters such as bandwidth allocation, transmission power, and packet prioritization based on current network conditions and communication requirements. This allows the network to adapt to varying loads and maintain audio quality by changing operational parameters rather than relying on fixed configurations.
2Ease of operation
If participants use personal mobile terminals to speak during the conference, then microphone logistics are simplified, but speaker location identification becomes difficult
Solution Approach 1:
The patent introduces an intermediary system consisting of acoustic cameras and signal processing algorithms that mediate between the speaker's mobile terminal and the conference system. This intermediary captures acoustic signals, processes them to determine speaker location, and provides this information to the conference management system, thereby solving the location identification problem without requiring physical microphones.
Solution Approach 2:
The system replaces the mechanical microphone passing system with an electronic acoustic field-based detection system. Instead of physically locating and passing microphones to speakers, the system uses acoustic sensors and signal processing to automatically detect and identify speaker locations and voices, substituting mechanical operations with electronic and computational methods.
3Productivity
If there is a delay between receiving a request to speak and actually speaking, then queue management is necessary, but the contribution may no longer be relevant to the presentation
Solution Approach 1:
The system performs preliminary actions by pre-processing and buffering audio contributions during the waiting period in queue. Audio signals are captured, encoded, and prepared for transmission in advance, so that when a speaker's turn arrives, the contribution can be immediately broadcast without delay. This preliminary preparation maintains the timeliness and relevance of contributions despite queue management requirements.

AI summary
A method for managing speaking turns, between a first mobile terminal and a second terminal, the first and second terminals being included in a set of interconnected terminals via a first communication network. The method including, following reception and validation on the second terminal of a connection request sent by the first terminal, the acts of configuring, for each of the terminals of the assembly apart from the first and second terminals, a first communication restriction for the connections using the first communication network and, establishing a communication between the first and the second terminal. On detecting the end of the communication, the method further includes removing the communication restriction for the set of terminals.
