Solution Overview

Problem

Current communication technologies do not support the temporary regrouping of multiple Mission Critical Push to Talk (MCPTT) groups, which is necessary for emergency situations where different departments need to communicate effectively.

Innovation Solution

A method and device that allow for the creation of a temporary group by a first group management functional entity, which receives a group regrouping creation message and configures information about the temporary group, including its identifier and the identifiers of the MCPTT groups to be regrouped, enabling communication between user equipment (UE) of MCPTT users across multiple groups.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional MCPTT group management is used, then group structure stability is maintained, but adaptability for emergency multi-group communication is insufficient

Engineering Contradiction:
Improveadaptability for emergency multi-group communicationVSAvoidgroup structure stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent implements dynamic group regrouping by allowing MCPTT users to temporarily regroup multiple MCPTT groups into a new group based on emergency requirements. The group management functional entity dynamically creates, manages, and releases temporary groups, enabling the system to adapt its structure in real-time while maintaining the stability of original groups through optional participation mechanisms.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If manual reconfiguration is implemented for emergency communication, then communication flexibility is improved, but operation complexity and time consumption increase

Engineering Contradiction:
Improveoperation simplicity for group regroupingVSAvoidtime for group reconfiguration
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent enables MCPTT users to autonomously initiate group regrouping operations by sending regrouping requests to the group management functional entity. The system automatically processes these requests, creates temporary groups, and manages communication resources without requiring manual operator intervention, thereby simplifying operations and reducing reconfiguration time.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If multiple MCPTT groups are regrouped into a temporary group, then communication coverage is expanded, but system complexity increases

Engineering Contradiction:
Improvecommunication coverageVSAvoidsystem complexity for group management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a group management functional entity as an intermediary between MCPTT users and the core network. This intermediary automatically manages the complex processes of temporary group creation, resource allocation, and coordination, thereby expanding communication coverage across multiple groups while shielding users from the underlying system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If temporary group creation is enabled, then communication versatility is improved, but control complexity increases

Engineering Contradiction:
Improvecommunication versatilityVSAvoidcontrol complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent establishes predefined regrouping rules and user authorization levels before emergency situations occur. The group management functional entity is pre-configured with policies for automatic group creation, resource allocation, and user permissions, enabling versatile temporary group formation during emergencies while maintaining straightforward control through pre-established protocols.

Inventive Principle:
Principle #10Preliminary action

AI summary

Embodiments of the present invention provide a method for regrouping multiple groups and a device. The method includes: receiving, by a first group management functional entity, a group regrouping creation message sent by first UE, where the group regrouping creation message includes identifiers of N MCPTT groups, and the group regrouping creation message is used to request the first group management functional entity to create, according to the identifiers of the N MCPTT groups, a temporary group which is initiated by a first MCPTT user and into which the N MCPTT groups are regrouped; the first group management functional entity is a group management functional entity in a home network of the first MCPTT user; and the first MCPTT user belongs to at least one MCPTT group of the N MCPTT groups; and configuring information about the temporary group, where the information about the temporary group includes an identifier of the temporary group into which the N MCPTT groups are regrouped, and the identifiers of the N MCPTT groups, so as to regroup the N MCPTT groups.
