Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In wireless communications, the asynchronous nature of message ordering leads to inefficiencies in correlating messages within a transaction, resulting in high network resource overhead due to the need for a separate transaction identifier field in each message.

Innovation Solution

Constructing a message identifier field as a combination of a transaction identifier and a message index, which reduces message size and saves network capacity by eliminating the need for a separate transaction identifier in subsequent messages within a transaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate transaction identifier field is added to every message to correlate messages within a transaction, then message correlation reliability is improved, but network resource overhead increases

Engineering Contradiction:

Improvemessage correlation reliabilityVSAvoidnetwork resource overhead

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent combines the transaction identifier and message identifier into a single unified message identifier field. Instead of adding a separate transaction identifier field to every message, the invention merges both identification functions into one field, thereby maintaining message correlation reliability while eliminating the additional network overhead that would result from duplicate identifier fields.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The message identifier field is designed to serve multiple functions simultaneously: it acts as both the unique message identifier and the transaction identifier. This multi-functional approach allows the same field to fulfill both identification needs, preventing the necessity of adding a separate transaction identifier field and thus reducing network resource consumption.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Measurement precision

If a transaction identifier field is added to every message to handle asynchronous message ordering, then message tracking accuracy is improved, but message size increases

Engineering Contradiction:

Improvemessage tracking accuracyVSAvoidmessage size

Core Design Contradiction:

Measurement precisionVSLength of stationary object

Solution Approach 1:

The patent merges the transaction identifier and message identifier into a single message identifier field, eliminating the need for a separate transaction identifier field. This consolidation maintains precise message tracking capability while reducing the overall message size by removing redundant identifier fields.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention extracts the transaction identification function from being a separate field and integrates it into the existing message identifier field. This extraction and integration approach maintains tracking accuracy while eliminating the additional space that would be required for a separate transaction identifier field.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A method and system for correlating messages within a wireless transaction, each of the messages requiring a unique message identifier, the method having the steps of: creating a transaction identifier, the transaction identifier being the same for related messages; and adding to the transaction identifier a message index, the message index corresponding to a number of a message within a transaction, whereby the transaction identifier and message index form the unique message identifier for each of the messages.
