Solution Overview

Problem

The existing methods for associating priority information with group call categories in mobile telephone networks are not user-friendly, requiring users to memorize sequences of digits and leading to network congestion when many users request high-priority group calls, as the same priority level is applied universally regardless of geographical area.

Innovation Solution

A method that allows users to associate priority information with each group call category and geographical area, enabling customizable priority settings and prioritizing the right to speak within a group call, with priority information stored on a removable memory medium like a SIM card for seamless terminal changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a universal priority level is applied to all group calls regardless of geographical area, then the system is simple to implement, but network congestion occurs when many users request high-priority group calls

Engineering Contradiction:
Improvesimplicity of priority assignmentVSAvoidnetwork capacity
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent applies local quality by allowing priority information to vary according to geographical area. Each group call category can have different priority levels assigned to different geographical areas, enabling the system to manage network resources locally rather than applying a universal priority level everywhere. This resolves the contradiction by maintaining simplicity in the assignment mechanism while improving network capacity through localized priority management.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent segments the network into multiple geographical areas, each with its own priority assignments for group call categories. This segmentation allows the network to handle priority requests independently in different regions, preventing a single high-priority request from causing congestion across the entire network. The segmentation principle enables the system to maintain operational simplicity while improving overall network productivity.

Inventive Principle:
Principle #1Segmentation

2Productivity

If users can associate priority information with each group call category and geographical area, then network congestion is reduced, but the system complexity increases

Engineering Contradiction:
Improvenetwork capacityVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements self-service by allowing users to automatically associate priority information with group call categories during subscription, without requiring manual configuration for each call. The system automatically retrieves and applies the appropriate priority level based on the group call category and geographical area, reducing system complexity while maintaining improved network capacity management.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent applies preliminary action by pre-associating priority information with group call categories during the subscription process. Users select their desired priority levels in advance, and these associations are stored and automatically applied when initiating calls. This eliminates the need for complex real-time priority assignments, reducing system complexity while maintaining the network capacity benefits of localized priority management.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If priority information is stored on a removable memory medium, then the service becomes more flexible for terminal changes, but the ease of initial setup decreases

Engineering Contradiction:
Improveflexibility with terminal changesVSAvoidinitial setup convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies universality by storing priority information on a removable memory medium that can be used across multiple terminals. The priority associations are tied to the user rather than a specific device, allowing the same priority settings to be automatically applied regardless of which terminal is used. This provides flexibility with terminal changes while maintaining ease of operation through automatic retrieval and application of stored priority information.

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

AI summary

The present invention relates to a method of determining associations between priority information and group call categories of a group call service deployed on a mobile telephone network. A call priority level being one of said items of priority information, the method is characterized in that it comprises, furthermore, a step (100) of creating an association between priority information and group call category in the course of which a call priority level is associated with each group call category distributed over a geographical zone of said telephone network and subscribed to by a user, the subscription being with a provider of said service in respect of said geographical zone.
