Dynamic Telephone Directory Reordering for PTT Efficiency

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In PTT communication systems, users face inefficiency in finding frequent speakers within a telephone directory list, as individuals who speak the most are often listed at the end or on subsequent pages due to alphabetical ordering, leading to increased time spent scrolling or turning pages.

Innovation Solution

The method rearranges the order of users in the telephone directory list based on the number of speeches made, with frequent speakers appearing higher in the list, and includes options to display them differently, such as with a different color or icon, to facilitate quicker identification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the telephone directory list is arranged in alphabetical order, then the directory list maintains a simple and systematic structure, but frequent speakers are located at the end or on subsequent pages requiring more scrolling time

Engineering Contradiction:

Improveease of finding frequent speakersVSAvoidtime spent scrolling through directory

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent applies dynamics by making the directory list arrangement changeable based on communication behavior. The system dynamically reorders the directory list according to the number of speeches made by each user, transitioning from a static alphabetical arrangement to a dynamic behavior-based arrangement that adapts to usage patterns.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the ordering parameter of the directory list from alphabetical order to speech frequency order. By using the number of speeches as the new sorting parameter, the system prioritizes frequent speakers at the top of the list, reducing the time needed to locate them.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If the telephone directory list is arranged alphabetically, then the structure remains simple and systematic, but users must turn pages or scroll extensively to locate frequent speakers

Engineering Contradiction:

Improveefficiency of initiating PTT communicationVSAvoidtime spent searching directory

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary action by pre-ordering the directory list based on speech frequency before the user needs to search. Frequent speakers are automatically positioned at the top of the list in advance, so when users need to initiate communication, the target contacts are already visible without requiring extensive scrolling.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from communication behavior (number of speeches) to continuously optimize the directory list arrangement. By monitoring speech frequency and using this information to reorder the list, the system learns from user interactions and improves search efficiency over time.

Inventive Principle:

Principle #23Feedback

AI summary

The present invention avoids taking much time for finding a person who speaks in a lot of numbers out of a telephone directory list of a mobile phone in a step of starting PTT communication. The device for receiving data receives voice signals from other mobile phones through a server. The device for controlling speaker's voice output outputs speaker's voice to a speaker, and further outputs his/her name to a display unit. The device for counting up a number of speeches counts up a number of speeches made by each of speakers stored in a telephone directory list. The device for terminating PTT communication terminates PTT communication. The device for re-arranging a telephone directory list re-arranges persons recorded in the telephone directory list, in accordance with a number of speeches.
