Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Mobile wireless communication devices experience unnecessary connection termination due to repeated retransmissions of obsolete measurement messages in dynamically changing network conditions, where the information becomes outdated before acknowledgement is received from the wireless communication network.

Innovation Solution

A method where the mobile wireless device stores a measurement message pending acknowledgement and updates it with new values if the parameters change, transmitting a second measurement message instead of retransmitting the obsolete first message, thereby avoiding unnecessary retransmissions and connection terminations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the mobile wireless communication device retransmits measurement messages without receiving an acknowledgement, then the device ensures message delivery reliability, but the transmitted information becomes obsolete and connection termination occurs

Engineering Contradiction:

Improvemessage delivery reliabilityVSAvoidmeasurement information obsolescence

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The mobile device performs preliminary actions by storing the latest measurement message content before retransmission attempts. When a new measurement is obtained during the acknowledgement waiting period, the device updates the stored message, ensuring that the most current information is transmitted rather than obsolete data.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The device implements a feedback mechanism where it continuously monitors whether new measurement data is available during the acknowledgement waiting period. This feedback loop allows the device to detect when measurement information has changed and adjust its retransmission strategy accordingly, preventing the transmission of outdated information.

Inventive Principle:

Principle #23Feedback

2Duration of action of stationary object

If the mobile wireless communication device continuously retransmits measurement messages, then the device maintains communication with the network, but unnecessary retransmissions consume network resources and lead to connection termination

Engineering Contradiction:

Improveconnection durationVSAvoidnetwork resource consumption

Core Design Contradiction:

Duration of action of stationary objectVSLoss of energy

Solution Approach 1:

The device prepares the latest measurement message content in advance before retransmission. By storing the current measurement data and updating it when new measurements are available, the device ensures that each retransmission contains valid, non-obsolete information, making the retransmission process efficient and necessary.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The device changes the parameter of measurement message content based on whether new measurements are available. When new measurement data is obtained during the acknowledgement waiting period, the device updates the message content parameter, ensuring that retransmissions carry updated information rather than repeating obsolete data.

Inventive Principle:

Principle #35Parameter changes

3Stability of the object's composition

If the mobile wireless communication device waits for acknowledgement before transmitting new measurement messages, then the device maintains protocol compliance, but the transmitted information becomes outdated in dynamic network conditions

Engineering Contradiction:

Improveprotocol complianceVSAvoidmeasurement data timeliness

Core Design Contradiction:

Stability of the object's compositionVSLoss of information

Solution Approach 1:

The device performs preliminary action by obtaining and storing the latest measurement message content during the acknowledgement waiting period. This allows the device to have updated measurement data ready, maintaining protocol compliance by waiting for acknowledgement while ensuring the information is current when the retransmission eventually occurs.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The device dynamically updates the measurement message content based on when new measurements are available during the acknowledgement waiting period. This dynamic approach allows the device to adapt to changing network conditions while maintaining protocol compliance, ensuring that the most current measurement information is transmitted.

Inventive Principle:

Principle #15Dynamics

AI summary

A method to control measurement messaging is performed at a mobile wireless device. The mobile wireless device transmits a first measurement message to a radio access network in a wireless network and stores the first measurement message pending receipt of an acknowledgement from the radio access network. Before receiving the acknowledgement to the first measurement message, the mobile wireless device determines at least one parameter included in the first measurement message requires updating. The mobile wireless device deletes the stored pending first measurement message and transmits a second measurement message to the radio access network including an updated value for the at least one parameter in the first measurement message.
