Solution Overview

Problem

In wireless communication systems, the transmission of capability information by electronic devices often results in large signal capacity, leading to network errors such as decoding failures, registration failures, and channel allocation failures, especially during processes like CSFB, due to the complexity of reporting multi-carrier aggregation capabilities.

Innovation Solution

An electronic device is equipped with a processor and communication module that checks and selects relevant capability information based on supported connection schemes, generates a message, and transmits it to the network, adapting the message size based on error detection and network codes to ensure accurate communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the electronic device transmits all capability information according to the communication standard, then the capability report is complete and accurate, but the signal capacity becomes large leading to network errors

Engineering Contradiction:

Improvecapability information accuracyVSAvoidsignal capacity

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent extracts only the necessary capability information related to supported connection schemes from the complete capability report, removing redundant information about other connection schemes. This selective extraction reduces signal capacity while maintaining the accuracy of essential capability information that the network needs for registration and channel allocation.

Inventive Principle:

Principle #2Taking out (Extraction)

2Productivity

If the electronic device includes multi-carrier aggregation capability information, then the transmission rate capability is fully reported, but the signal capacity increases causing decoding failures

Engineering Contradiction:

Improvetransmission rate capabilityVSAvoidsignal transmission reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent extracts only the essential capability information needed for network operation (supported connection schemes) while excluding detailed multi-carrier aggregation capability information. This extraction maintains the device's productivity capability representation while reducing signal capacity to prevent decoding failures and improve transmission reliability.

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If the capability report includes all supported connection schemes, then the device versatility is fully represented, but the message size becomes large causing registration failures

Engineering Contradiction:

Improveconnection scheme supportVSAvoidmessage size

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent extracts only the capability information related to supported connection schemes that are essential for network registration, excluding information about other connection schemes. This selective extraction maintains the device's adaptability representation while reducing message size to prevent registration failures.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the complete capability report into essential information (supported connection schemes) and non-essential information (other connection schemes). Only the essential segment is transmitted in the capability report message, reducing message size while maintaining registration capability.

Inventive Principle:

Principle #1Segmentation

4Measurement precision

If the electronic device transmits comprehensive capability information, then the network can make accurate channel allocation decisions, but the signal capacity increases causing channel allocation failures

Engineering Contradiction:

Solution Approach 1:

The patent extracts only the capability information necessary for channel allocation decisions (supported connection schemes) while removing redundant information. This extraction maintains the precision needed for accurate channel allocation while reducing signal capacity to prevent channel allocation failures and improve success rate.

Inventive Principle:

Principle #2Taking out (Extraction)
