Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current systems do not support the function of setting a selected MCPTT group for one MCPTT user or network system for another MCPTT user.

Innovation Solution

A method and system that allow a network device to receive a group selection request and send information about an MCPTT group to user equipment, enabling the setting of an MCPTT group as a selected group for a specific MCPTT user, with considerations for user authorization and group availability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a network device receives and processes group selection requests to set selected MCPTT groups for users, then the system's group management capability is improved, but the device complexity increases

Engineering Contradiction:

Improvegroup management capabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The network device is designed to perform multiple functions including receiving group selection requests, determining user authorization, checking group availability, and sending group information. This multi-functional approach allows a single device to handle various aspects of MCPTT group management, improving adaptability while managing complexity through consolidation rather than proliferation of separate components

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The network device acts as an intermediary between MCPTT users and the MCPTT groups. It mediates the group selection process by receiving requests from users, processing authorization and availability checks, and delivering appropriate group information. This intermediary role simplifies the overall system architecture by centralizing management functions in a dedicated mediator rather than distributing complexity across multiple components

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the system implements authorization checks and group availability determination, then the reliability of group selection is improved, but the processing time increases

Engineering Contradiction:

Improvegroup selection reliabilityVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The network device performs authorization determination and group availability checks as preliminary actions before finalizing the group selection. By proactively verifying user authorization status and group availability in advance, the system ensures reliable group selection outcomes while preparing the necessary information for efficient delivery to the user equipment

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The network device continuously maintains information about user authorization status and group availability, rather than performing these checks from scratch for each request. This continuous maintenance of useful information allows the device to quickly process new group selection requests by building upon previously gathered data, reducing processing time while maintaining high reliability

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A first network device receives a group selection request, where the group selection request is used to instruct to set a first MCPTT group as a selected MCPTT group for a first MCPTT user; and the first network device sends, according to the group selection request, information about the first MCPTT group to first UE used by the first MCPTT user, so that the first network device can set the first MCPTT group as a selected MCPTT group for the first MCPTT user.
