Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing push-to-talk (PTT) systems face challenges in providing real-time quality measurement and service adaptation due to the need for separate quality measurement servers and servers that may malfunction, leading to suboptimal service delivery based on the lowest processing power device, and lack of flexibility in network communication.
Innovation Solution
A device that transmits a heartbeat signal to PTT devices to assess their status in real-time, allocates segments of the PTT message based on response signals, and adjusts transmission methods accordingly, allowing direct communication without a central server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate quality measurement server is used to measure communication service quality for each PTT device, then measurement precision is improved, but device complexity increases and loss of time increases due to sequential measurement
Solution Approach 1:
The patent combines the quality measurement function with the PTT server into a single integrated system. The PTT server simultaneously performs both PTT service provision and communication quality measurement for multiple devices, eliminating the need for a separate quality measurement server and reducing system complexity while maintaining measurement precision
Solution Approach 2:
The patent implements continuous quality measurement during ongoing PTT communications. The server measures communication quality in real-time while services are being delivered, rather than performing separate sequential measurements, thereby reducing time loss and maintaining continuous operational efficiency
2Measurement precision
If quality measurement is performed sequentially for each PTT device, then measurement precision is maintained, but loss of time increases as the number of devices increases
Solution Approach 1:
The patent merges quality measurement for multiple PTT devices into a single simultaneous operation performed by the PTT server. Instead of sequentially measuring each device's quality one after another, the server conducts parallel measurements across all connected devices, dramatically reducing total measurement time while preserving measurement accuracy
Solution Approach 2:
The patent implements periodic quality measurement cycles where the server systematically measures communication quality for all PTT devices at regular intervals. This periodic approach ensures continuous monitoring of all devices without requiring sequential individual measurements, reducing overall time loss while maintaining precision
3Adaptability or versatility
If PTT service quality is determined based on the lowest processing power device, then adaptability is improved for all devices, but productivity decreases because high-performance devices cannot utilize their full capabilities
Solution Approach 1:
The patent applies local quality by customizing PTT service parameters individually for each device based on its specific processing capabilities. Instead of uniformly adapting all services to the lowest-performance device, the server identifies each device's capabilities and delivers appropriately optimized service quality, allowing high-performance devices to utilize their full potential while maintaining compatibility for all devices
Solution Approach 2:
The patent implements dynamic service adaptation where the server continuously monitors device performance and adjusts service parameters in real-time. This dynamic approach allows service quality to be optimized for each device's current state rather than being statically limited by the lowest-performance device, thereby improving overall system productivity while maintaining adaptability
4Reliability
If a central PTT server is used to provide services, then reliability is improved through centralized control, but device complexity increases and loss of time increases due to server dependency
Solution Approach 1:
The patent implements self-service capabilities where PTT devices can autonomously perform quality measurements and service optimizations without requiring constant centralized server intervention. Each device can independently assess its own communication quality and adjust parameters, reducing dependency on the central server while maintaining service reliability through distributed intelligence

AI summary
There is provided a device for transmitting a push-to-talk (PTT) message. The device includes a communication interface, and an operation processor that transmits a first segment group of the PTT message among segments of the PTT message to first to n-th PTT devices through the communication interface; transmits a heartbeat signal to the first to n-th PTT devices through the communication interface; receives an i-th response signal to the heartbeat signal from an i-th PTT device through the communication interface; allocates, based on the i-th response signal, the i-th PTT device to a first group to which a second segment group of the PTT message is transmitted without any conversion or a second group to which data obtained by converting the second segment group is transmitted; and transmits the second segment group to the first group and the data to the second group through the communication interface.
