Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IP telephones consume excessive power due to processes like digitizing sound data, restoring packets, and wireless communication, leading to battery drain and inability to be used continuously.
Innovation Solution
An IP telephone system that switches between standard and power-saving communication modes, stopping transmission of low-level sound data and interrupting data transmission during inactive periods to conserve battery power, using a data transmission and reception controller to manage these modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound data is continuously transmitted and received between communication devices through the IP network, then communication quality is maintained, but battery power is consumed rapidly
Solution Approach 1:
The patent implements periodic action by switching between standard communication mode and power-saving communication mode based on communication activity. In power-saving mode, the system periodically transmits only detection packets at extended intervals rather than continuous sound data transmission, thereby reducing battery consumption while maintaining basic connection functionality.
Solution Approach 2:
The communication system dynamically adjusts its operation mode based on real-time conditions. The data transmission and reception controller switches between standard mode (full communication quality) and power-saving mode (reduced transmission) according to whether communication is active or idle, optimizing the balance between quality and power consumption.
2Measurement precision
If digitizing and processing sound data is performed continuously, then communication fidelity is maintained, but power consumption increases
Solution Approach 1:
The patent extracts only the essential communication function by stopping the transmission and processing of sound data in power-saving mode. Only detection packets are transmitted to maintain connection, while full sound data digitizing and processing are suspended, thereby eliminating unnecessary power consumption while preserving basic communication capability.
3Reliability
If wireless packet communication is maintained continuously, then connection reliability is ensured, but battery capacity depletes quickly
Solution Approach 1:
The system employs periodic action by transmitting detection packets at extended intervals during power-saving mode rather than maintaining continuous wireless communication. This periodic transmission maintains basic connection reliability while significantly reducing power consumption, thereby extending battery usage duration.
4Use of energy by moving object
If all sound data transmission is stopped to save power, then battery life is extended, but communication quality deteriorates
Solution Approach 1:
The system dynamically switches between two operational states: standard mode for high-quality communication and power-saving mode for extended battery life. The data transmission and reception controller adjusts the transmission mode based on communication activity, ensuring that communication quality is maintained when needed while extending battery life during idle periods.

AI summary
An IP telephone system according to the present invention includes a plurality of communication devices T1, T2 allowed to mutually communicate through a network (IP network); a server for executing a connection starting process of communication between the communication devices, as well as for controlling communication data transmitted and received between the server and the communication devices during the communication between the communication devices; and a data transmission and reception controller for mutually switching, upon input of a predetermined command, a communication mode between a standard communication mode and a power-saving communication mode in a condition that communication connection is established between the communication devices upon execution of the connection starting process. The sound data is transmitted and received between the communication devices and the server in the standard communication mode. Transmission and reception between the communication devices and the server is stopped with respect to the sound data below a predetermined level while being continued with respect to the sound data beyond the predetermined level received in the power saving communication mode.
