Solution Overview

Problem

Users in a talk group need to manually switch between groups when moving to different locations, which is inconvenient, especially in scenarios like franchise shops or factories with multiple branches.

Innovation Solution

An information processing apparatus that automatically determines and switches a user's talk group based on terminal location information, using a storage to store correspondence relationships between talk groups and geographical areas, and a determining unit to assign the appropriate group.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual group switching is implemented, then users can belong to specific talk groups at specific locations, but user convenience deteriorates due to the need for manual withdrawal and participation in groups

Engineering Contradiction:
ImproveUser convenience in talk group managementVSAvoidTime required for manual group switching
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system enables automatic talk group switching based on terminal location information. The determining unit automatically identifies which talk group the terminal should belong to based on stored correspondence relationships between locations and talk groups, and the setting unit automatically switches the terminal's talk group membership without requiring manual user intervention. This self-service mechanism resolves the contradiction by eliminating manual operations while maintaining accurate location-based group assignment.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-stores correspondence relationships between locations and talk groups in advance. When a terminal's location is obtained, the determining unit quickly matches it against the pre-stored relationships to determine the appropriate talk group. This preliminary preparation of location-group mappings enables rapid automatic switching without time-consuming manual configuration, resolving the time loss issue.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If automatic talk group switching based on location is implemented, then user convenience is improved, but system complexity increases due to storage and determination mechanisms

Engineering Contradiction:
ImproveAutomatic talk group switchingVSAvoidSystem structure for location-based group management
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The information processing apparatus integrates multiple functions into a single system: the storage unit stores location-group correspondence relationships, the obtaining unit acquires terminal location information, the determining unit determines appropriate talk groups, and the setting unit switches group membership. This multi-functional integration achieves automatic location-based talk group switching while managing system complexity through a unified apparatus design.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The determining unit acts as an intermediary between the location information and the talk group switching mechanism. It receives terminal location information, matches it against stored correspondence relationships, and outputs the determined talk group to the setting unit. This intermediary layer simplifies the overall system architecture by centralizing the decision-making logic for group switching.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An information processing apparatus is configured to associate multiple terminals with a talk group and to enable one-to-many communications from one of the terminals belonging to the talk group to a remaining one or more of the terminals belonging to the talk group. The information processing apparatus includes a storage unit, an obtaining unit, a determining unit, and a setting unit. The storage unit stores a correspondence relationship between one or more talk groups and one or more group location information items about an area defining the one or more talk groups. The obtaining unit obtains terminal location information about a location of each terminal. The determining unit determines, based on the terminal location information and the correspondence relationship, a talk group to which each terminal is to belong. The setting unit switches a talk group to which each terminal currently belongs to the determined talk group.
