Solution Overview

Problem

Next-generation mobile communications networks face challenges in managing increased capacity and device variety, leading to potential network congestion and reduced quality of service, particularly in uplink transmissions where resource requests from numerous devices can cause inefficient resource allocation and increased power consumption.

Innovation Solution

A communications system that allows communications terminals to indicate transmission priority levels in resource request messages, enabling infrastructure equipment to allocate resources more efficiently and promptly, thereby prioritizing high-priority data and reducing unnecessary resource requests.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a large number of communications devices transmit resource requests in the uplink, then the network can serve more devices, but network congestion occurs and resource allocation efficiency decreases

Engineering Contradiction:

Improvenumber of communications devices servedVSAvoidresource allocation efficiency

Core Design Contradiction:

Quantity of substanceVSProductivity

Solution Approach 1:

The resource request mechanism is segmented by introducing priority levels that divide traffic into different categories. High-priority devices receive dedicated resource allocation channels while low-priority devices use shared channels, preventing congestion from uniform traffic handling and maintaining allocation efficiency as device numbers increase.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system changes the parameter of resource requests by incorporating priority indicators that modify how requests are processed. Infrastructure equipment uses these priority parameters to differentiate between devices, allocating resources based on urgency rather than treating all requests equally, thus maintaining efficiency under high device density.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If resource requests are transmitted frequently to ensure data transmission, then data transmission reliability improves, but power consumption increases

Engineering Contradiction:

Improvedata transmission reliabilityVSAvoidpower consumption at communications terminal

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

Instead of all devices transmitting resource requests at full frequency, the system applies partial action by allowing only high-priority devices to transmit frequently while low-priority devices transmit less often. This reduces overall power consumption while maintaining reliability for critical communications.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system performs preliminary prioritization at the device level before transmission, where devices determine their own priority status and adjust their resource request frequency accordingly. High-priority devices prepare and send requests proactively, while low-priority devices wait for lower-frequency opportunities, reducing unnecessary transmissions and power consumption.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If priority indication is added to resource request messages, then resource allocation efficiency improves, but message complexity increases

Engineering Contradiction:

Improveresource allocation efficiencyVSAvoidmessage structure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The priority indication is implemented as a localized modification within the existing message structure rather than a complete redesign. The priority field is inserted at a specific location in the message, allowing infrastructure equipment to quickly extract and act on priority information without processing complex restructured messages, thus maintaining low complexity while improving allocation efficiency.

Inventive Principle:

Principle #3Local quality

AI summary

A communications system communicating data to/from a communications terminal includes infrastructure equipment forming a mobile communications network to transmit/receive data to/from the communications terminal via a wireless access interface, the communications terminal configured to transmit/receive data to/from the infrastructure equipment. The communications terminal can receive transmission data to the infrastructure equipment at a buffer, transmit a resource request message requesting resources of the wireless access interface to the infrastructure equipment in response to receiving the data for transmission to the infrastructure equipment, and receive a resource allocation message from the infrastructure equipment. The resource allocation message allocates resources of the wireless access interface to the communications terminal. A characteristic of the resource request message transmitted by the communications terminal to the infrastructure equipment provides an indication of one of a predetermined set of transmission priority levels for transmitting the buffered data to the infrastructure equipment.
