Telephone Control Apparatus Ringtone Segmentation for Call Group Distinction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telephone systems cannot distinguish which incoming call group is receiving a call when a single telephone terminal belongs to multiple groups, and it is difficult to differentiate between a single incoming call and multiple incoming calls to multiple groups.
Innovation Solution
A telephone control apparatus that stores unique ringtone patterns for each incoming call group and controls telephone terminals to ring based on these patterns, allowing for distinct ringtone patterns to be used for each group, even when a terminal belongs to multiple groups and multiple groups receive calls simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single common ringtone is used for all incoming call groups, then the system is simple to operate, but it becomes impossible to distinguish which incoming call group is receiving a call
Solution Approach 1:
The patent divides the single common ringtone into multiple distinct ringtone patterns, each assigned to a specific incoming call group. The controlling unit selects and plays the ringtone pattern corresponding to the specific incoming call group that is receiving the call, enabling clear distinction between different call groups while maintaining operational simplicity through automated selection.
2Loss of information
If different ringtones are used for each telephone terminal or line group, then incoming call groups can be distinguished, but it becomes difficult to handle cases where a single terminal belongs to multiple groups receiving calls simultaneously
Solution Approach 1:
The patent implements a dynamic ringtone selection mechanism where the controlling unit determines the appropriate ringtone pattern based on the real-time status of incoming call groups. When a terminal belongs to multiple incoming call groups, the system dynamically selects which ringtone to play based on which specific group is receiving the call, or plays both ringtone patterns simultaneously if multiple groups are receiving calls, thus adapting to various operational scenarios.
3Device complexity
If the same ringtone is used for all incoming call groups, then the device complexity is low, but it is impossible to determine whether one or multiple incoming call groups are receiving calls
Solution Approach 1:
The patent establishes a feedback mechanism where the controlling unit monitors the status of each incoming call group and selects ringtone patterns accordingly. When multiple incoming call groups are receiving calls simultaneously, the system provides feedback by playing multiple distinct ringtone patterns, enabling users to understand the call status information without increasing overall system complexity, as the selection process is automated.

AI summary
There is provided an telephone control apparatus including storing unit for storing ringtone patterns for each incoming call group relative to one or more telephone terminals; and controlling unit for performing a ring operation of the telephone terminal belonging to the incoming call group which is to receive a call based on the ringtone pattern specified from the storing unit, wherein when a certain incoming call group among the plural incoming call groups becomes in a call receiving condition, the controlling unit specifies the ringtone pattern corresponding to the incoming call group in a call receiving condition by referring to the storing unit and controls the telephone terminals belonging to the incoming call group in the call receiving condition to perform a ring operation based on the ringtone pattern.
