Solution Overview
Problem
Existing relay apparatuses face challenges in efficiently recording voice communications, requiring new hardware for external extraction and increasing the load on controllers, while also struggling to track and record communications from specific terminals.
Innovation Solution
A relay apparatus with a communicator, communication session processor, and communication monitor that registers participating terminals, transmits voice signals with session information, and records voice signals from specific terminals by establishing virtual communication sessions and buffering signals in volatile memory for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new recording function is added to a relay apparatus, then voice communication recording capability is improved, but the load on the controller increases and the addition process becomes time-consuming
Solution Approach 1:
The relay apparatus is divided into distinct functional modules: a communication session processor that handles voice signal transmission and a communication monitor that handles recording operations. This segmentation allows the recording function to operate independently without increasing the load on the controller, as each module processes its designated tasks separately
Solution Approach 2:
The communication monitor serves multiple functions: it monitors communication sessions, extracts voice signals from transmitted data, and performs recording operations. By making this component multi-functional, the system achieves recording capability without adding separate dedicated hardware, thereby avoiding increased controller load
2Ease of operation
If external extraction of voice signal is implemented, then voice signal output capability is improved, but new hardware requirements increase device complexity
Solution Approach 1:
The communication monitor extracts the voice signal from the transmitted data stream by identifying and separating voice signal packets from other communication data. This extraction is achieved through software-based packet analysis rather than physical signal separation, eliminating the need for additional external hardware while maintaining voice signal output capability
Solution Approach 2:
The patent replaces physical/mechanical signal extraction hardware with a software-based communication monitor that processes and extracts voice signals digitally. The monitor analyzes transmitted data packets, identifies voice signal portions, and outputs them without requiring physical signal routing hardware, thereby reducing device complexity
3Measurement precision
If individual terminal tracking is implemented, then communication tracking capability is improved, but the complexity of monitoring multiple terminals increases
Solution Approach 1:
The communication monitor is pre-configured with terminal identification information before monitoring begins. When a communication session is established, the monitor already has the criteria needed to identify and track specific terminals, eliminating the need for complex real-time analysis and reducing monitoring complexity while maintaining precise terminal identification
Data Source
AI summary
There is provided a relay apparatus that enables a communication voice of a specific communication terminal to be tracked and recorded. A call from a communication terminal results in establishment of a communication session in which the calling communication terminal and a called communication terminal are regarded as participating terminals. Transmission of a voice signal from any of the participating terminals in the established communication session allows the voice signal to be transmitted, together with session information, to the other participating terminal in the same communication session. A virtual device is associated with the communication terminal, and the communication terminal and the virtual device establish a virtual communication session. In the virtual communication session, the voice signal transmitted from the communication session to the virtual device is recorded in a communication monitor.
