Solution Overview

Problem

In machine-type communication (MTC) systems, the existing method of reporting capability parameters from MTC devices to the network side consumes large air interface resources, leading to inefficiency and increased costs.

Innovation Solution

The method involves mapping a combination of capability parameters to an index based on a predefined rule, allowing the MTC device to report the index instead of individual parameters, which reduces the air interface resources required for reporting and simplifies the network side's analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the MTC device reports capability parameters item by item to the network side, then the network side can obtain complete capability information for resource allocation and configuration, but large air interface resources are consumed

Engineering Contradiction:

Improvecapability information completenessVSAvoidair interface resource consumption

Core Design Contradiction:

Loss of informationVSLoss of energy

Solution Approach 1:

The patent combines multiple capability parameters into a single capability index. Instead of reporting each capability parameter separately, the MTC device maps a combination of capability parameters to one index value, which is then reported to the network side. This merging approach maintains complete capability information while significantly reducing air interface resource consumption.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent transforms multiple capability parameters into a single capability index through mapping. The network side and MTC device establish a correspondence relationship between capability parameters and index values, allowing the device to report a single index that represents multiple capability characteristics, thereby changing the parameter representation from multiple individual parameters to one composite index.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If multiple capability parameters are reported separately, then detailed capability information is provided, but the reporting process becomes complex and time-consuming

Engineering Contradiction:

Improvecapability parameter detailVSAvoidcapability reporting time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent merges multiple capability parameters into a single capability index, allowing the MTC device to report all capability information in one index value rather than transmitting each parameter separately. This significantly reduces the time required for capability reporting while the network side can still retrieve detailed capability information by mapping the received index back to the original capability parameters using the pre-established correspondence relationship.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent establishes the correspondence relationship between capability parameters and index values in advance, before the actual capability reporting occurs. Both the network side and MTC device pre-configure the mapping rules, so that during capability reporting, the device can quickly map its capabilities to an index and the network side can rapidly interpret the index to obtain detailed capability information, avoiding time-consuming real-time processing.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If individual capability parameters are reported, then the network side can perform detailed resource allocation, but the air interface overhead increases

Engineering Contradiction:

Improveresource allocation precisionVSAvoidair interface overhead

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The patent combines multiple capability parameters into a single capability index for reporting over the air interface. This merging reduces the air interface overhead by transmitting one index value instead of multiple separate parameters. The network side maintains the ability to perform detailed resource allocation by mapping the received index back to the original capability parameters using the pre-established correspondence relationship, thus preserving resource allocation precision.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts the essential capability information into a compact index form for air interface transmission. By taking out only the necessary capability representation (the index) rather than transmitting all raw capability parameters, the air interface overhead is reduced while the network side can extract the full capability details by mapping the index to the corresponding capability parameters using the pre-configured correspondence relationship.

Inventive Principle:

Principle #2Taking out (Extraction)
