IP Facsimile Communication Device Dynamic Network Mode Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication devices with IP facsimile functions face operational certification issues when the pre-set operation mode does not match the network environment, leading to failed call control in varying network settings such as Internet and Next-Generation Network (NGN) environments.
Innovation Solution
A communication device that performs DHCP negotiation upon activation to acquire network parameters, analyzes these parameters to identify the network environment, and selects an appropriate operation mode based on the network identification information, ensuring compatible call control protocols are used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pre-set operation mode is used in IP facsimile devices, then the device can operate with simple configuration, but the operation mode may not match the actual network environment leading to failed call control
Solution Approach 1:
The patent implements dynamic operation mode selection by having the facsimile device automatically detect network environment parameters (such as SIP server presence, network type) and switch between different operation modes (Internet mode, NGN mode, etc.) based on the detected environment, rather than using a fixed pre-set mode
Solution Approach 2:
The device performs self-diagnosis of the network environment by automatically acquiring network parameters through DHCP negotiation and analyzing them to determine the appropriate operation mode without requiring administrator intervention or manual configuration
2Reliability
If the operation mode is manually configured by administrator, then the call control can be optimized for specific network environment, but it requires administrator intervention and manual configuration
Solution Approach 1:
The facsimile device automatically performs network environment detection and operation mode selection without requiring administrator intervention. The device acquires network parameters, analyzes them to identify the network type, and autonomously selects the appropriate operation mode
Solution Approach 2:
The system implements a feedback mechanism where the device continuously monitors network environment parameters and adjusts the operation mode based on the detected conditions, ensuring the operation mode always matches the current network environment
3Adaptability or versatility
If multiple operation modes are supported to cover different network environments, then the device can adapt to various networks, but the device complexity increases
Solution Approach 1:
The patent introduces an operation mode selection unit that acts as an intermediary between the network environment and the facsimile communication functions. This unit automatically analyzes network parameters and selects the appropriate operation mode, shielding users from the complexity of multiple modes while maintaining adaptability
Solution Approach 2:
The system changes operational parameters (operation mode) based on detected network environment parameters (SIP server presence, network type, DHCP options) to optimize performance for each specific network condition

AI summary
A communication device includes a first acquisition unit that acquires communication setting information of communication device from a server, the communication setting information being information necessary for communication between communication devices through a communication network; a second acquisition unit that acquires network identification information, which is information for identifying the communication network to which the communication device is connected, on the basis of the communication setting information acquired by the first acquisition unit; and a selection unit that, in accordance with the network identification information acquired by the second acquisition unit, selects an operation scheme of the communication device when the communication device communicates with another device through the communication network.
