Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In MCPTT systems, users cannot currently change the association relationship between another user and a group, limiting dynamic management of group communications.

Innovation Solution

A method and apparatus where a first network element device receives an association change request from a user equipment (UE) to modify the association relationship between a second MCPTT user and an MCPTT group, allowing authorized users to change the association status of other users within a group.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an MCPTT user sends a group association request message to establish an association relationship with an MCPTT group, then the user can join group communication, but the user cannot change the association relationship between another user and the group

Engineering Contradiction:

Improveuser control over group associationVSAvoidassociation relationship modification capability

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces dynamic modification capability to the static association relationship between users and groups. By enabling authorized users to change association relationships through network element devices, the system transitions from a fixed join/leave model to a dynamic management model where users can be added or removed from groups during operation, enhancing adaptability while maintaining operational simplicity through authorized control mechanisms

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If authorized users can change association relationships between other users and groups, then service flexibility is enhanced, but system complexity increases

Engineering Contradiction:

Improvedynamic group managementVSAvoidassociation change request processing

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces network element devices as intermediary components that mediate between users and group association changes. These intermediaries receive association change requests from authorized users, validate permissions, and execute the association modifications. This intermediary layer simplifies the overall system architecture by centralizing the complexity of association management in dedicated network elements rather than requiring complex peer-to-peer coordination between users

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Embodiments of the present invention provide a method, an apparatus, and a system for changing an association relationship between an MCPTT user and an MCPTT group. A method for changing an association relationship between an MCPTT user and an MCPTT group includes: receiving, by a first network element device, an association change request sent by first user equipment UE, where the association change request includes request information, the request information is used to indicate that a first mission critical push to talk MCPTT user requests to change an association relationship between a second MCPTT user and a first MCPTT group, and the first MCPTT user is an MCPTT user using the first UE; and setting, by the first network element device, the association relationship between the second MCPTT user and the first MCPTT group according to the association change request. The present invention implements that an MCPTT user changes an association relationship between another MCPTT user and a group.
