Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In Mission Critical Data (MCData) communication systems, there is a challenge in identifying the sender of data within group sessions, as existing technologies do not provide a mechanism for User Equipment (UE) to include a sender user identifier (ID) in the signaling payload, making it difficult for receiver UEs to determine the source of the data.

Innovation Solution

A method and system where the sender UE adds a sender user identifier (ID) to the signaling payload of data transmitted during a MCData session, enabling receiver UEs to decode and identify the sender UE, thereby facilitating the identification of data origin within group sessions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If sender UE includes sender user ID in signaling payload, then receiver UE can identify the sender of data, but signaling payload structure becomes more complex

Engineering Contradiction:

Improvesender identification informationVSAvoidsignaling payload structure

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The sender user ID is nested within the existing signaling payload structure as a contained element, similar to how information elements are nested within MCData messages. This allows the sender ID to be integrated without creating a separate complex structure, resolving the contradiction by embedding the identification information within the existing framework.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The signaling payload structure is designed to serve multiple functions: it carries both the sender user ID for identification purposes and the actual MCData content for communication. This multi-functionality allows a single structure to handle both identification and data transmission, reducing the need for separate complex structures.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If sender UE adds sender user ID to signaling payload, then transparency and management in MCData sessions is enhanced, but processing overhead increases

Engineering Contradiction:

Improvesender identification accuracyVSAvoidprocessing overhead

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The sender user ID is added to the signaling payload in advance during the data transmission preparation phase, rather than being processed or generated at the moment of reception. This preliminary action allows receiver UEs to identify senders without requiring complex real-time processing, reducing processing overhead while maintaining identification accuracy.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If existing MCData signaling payload structure is used without modification, then device complexity is minimized, but sender identification capability is lost

Engineering Contradiction:

Improvesignaling payload structureVSAvoidsender identification information

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The signaling payload is segmented into distinct information elements, with one specific element dedicated to carrying the sender user ID. This segmentation allows the existing payload structure to be maintained for overall compatibility while adding the necessary sender identification capability through a dedicated, clearly-defined segment.

Inventive Principle:

Principle #1Segmentation
