Communication Apparatus Direct Network Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems between heterogeneous networks, such as PSTN and UHF-AM, require gateways for data format conversion, leading to transmission delays and security vulnerabilities due to reprocessing of information security schemes.
Innovation Solution
A communication apparatus that directly transmits digitized and packetized data between networks using a modem, eliminating the need for gateways and allowing real-time communication by employing a common information security scheme and processing both speech and non-speech data through a single module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a gateway is used to convert data formats between heterogeneous networks, then compatibility between different network types is improved, but transmission delay increases due to conversion and reprocessing operations
Solution Approach 1:
The patent extracts the data format conversion function from the communication path by enabling direct communication between heterogeneous networks without requiring a gateway. The terminal devices perform format adaptation locally, removing the intermediate conversion step that causes delay while maintaining compatibility.
Solution Approach 2:
Instead of using a gateway to convert formats centrally, the patent inverts the approach by enabling terminal devices to directly communicate in heterogeneous networks, with each terminal handling its own format conversion locally, thus eliminating the time-consuming centralized conversion process.
2Reliability
If a gateway reprocesses information security schemes for secure communication, then security compatibility between networks is improved, but security vulnerabilities increase due to reprocessing operations
Solution Approach 1:
The patent extracts the security reprocessing function from the gateway and relocates it to terminal devices. Each terminal maintains its own information security scheme locally, eliminating the need for gateway reprocessing that creates security vulnerabilities, while still achieving security compatibility through direct peer-to-peer secure communication.
3Adaptability or versatility
If data format conversion is performed at the gateway, then data compatibility between networks is improved, but device complexity increases due to the need for multiple conversion modules
Solution Approach 1:
The patent extracts the data format conversion capability from the gateway infrastructure and embeds it directly into terminal devices. This eliminates the need for complex gateway conversion modules while maintaining data compatibility, as each terminal independently handles format adaptation for direct communication with other heterogeneous networks.

AI summary
Provided is a communication apparatus for direct communication between networks of different types. The communication apparatus includes a transmission data selector determining whether or not data input from a first communication network is speech data, a data processor digitizing and packetizing the data transferred from the transmission data selector, and a modem for converting the digitized and packetized data into analog data and then directly transmitting the analog data to a second communication network different from the first communication network through a speech channel.
