Solution Overview

Problem

In LTE radio communication networks, base stations become congested due to limited radio resources, leading to prolonged data transmission times and increased power consumption, especially when multiple users request large data transmissions simultaneously, resulting in decreased efficiency.

Innovation Solution

A method where a base station acquires transmission attribute information from terminals, including priority, data amount, and delay requirements, to send scheduling suspension or start messages, suspending or initiating resource requests based on network conditions, thereby optimizing resource allocation and reducing congestion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the base station allocates radio resources to multiple UEs simultaneously, then the data transmission capacity increases, but the base station becomes congested and scheduling time increases

Engineering Contradiction:
Improvedata transmission capacityVSAvoidscheduling time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The base station performs preliminary assessment of transmission attribute information (data amount, priority, delay requirement) before actual resource allocation. This allows the base station to pre-plan resource distribution and avoid congestion during active scheduling, thereby reducing scheduling time while maintaining high data transmission capacity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention changes the parameter of resource allocation from uniform allocation to differentiated allocation based on transmission attribute information. By adjusting allocation parameters according to data amount, priority level, and delay requirements, the base station optimizes both throughput and scheduling efficiency, resolving the contradiction between capacity and time.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the base station serves multiple UEs with limited radio resources, then resource utilization increases, but the base station gets congested and data transmission efficiency decreases

Engineering Contradiction:
Improveresource utilizationVSAvoiddata transmission efficiency
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The base station applies different resource allocation strategies to different UEs based on their local characteristics (transmission attribute information). High-priority UEs with small data amounts receive quick service, while low-priority UEs with large data amounts are scheduled during off-peak times. This localized quality approach maintains high resource utilization while ensuring efficient data transmission for each UE.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The resource allocation scheme is dynamic rather than static. The base station continuously adjusts resource distribution based on real-time transmission attribute information and current network conditions. This dynamic adaptation allows the system to maintain high productivity and reliability simultaneously by responding to changing demands.

Inventive Principle:
Principle #15Dynamics

3Productivity

If the UE repeatedly requests radio resource scheduling, then the data transmission requirement is met, but the power consumption of the UE increases

Engineering Contradiction:
Improvedata transmission completionVSAvoidUE power consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The base station performs preliminary assessment of the UE's transmission attribute information and proactively allocates sufficient radio resources in advance. This prevents the UE from needing to repeatedly send scheduling requests, thereby reducing UE power consumption while ensuring complete data transmission. The base station anticipates future resource needs and prepares allocations beforehand.

Inventive Principle:
Principle #10Preliminary action

4Ease of operation

If the base station allocates small amounts of radio resources to each UE, then resource fairness is improved, but total data transmission time increases

Engineering Contradiction:
Improveresource fairnessVSAvoidtotal data transmission time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The invention changes the resource allocation parameter from fixed equal allocation to variable allocation based on transmission attribute information. The base station adjusts allocation size according to data amount, priority, and delay requirements, achieving both fairness (meeting all UEs' needs) and efficiency (minimizing total transmission time) simultaneously.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The base station implements periodic scheduling with different time allocations for different UEs based on their priorities. High-priority UEs receive more frequent and larger allocations, while low-priority UEs receive allocations during lower-traffic periods. This periodic differentiated action ensures fairness across all UEs while minimizing overall transmission time.

Inventive Principle:
Principle #19Periodic action

AI summary

Embodiments of the present invention provide a method and an apparatus for controlling data transmission on a radio communication network. The method includes: acquiring, by a base station, transmission attribute information, where the transmission attribute information includes attribute information of to-be-transmitted data and scheduling attribute information of the base station; and judging whether the acquired scheduling attribute information of the base station meets a preset scheduling condition; and if yes, the base station sends a scheduling suspension message and/or a scheduling start message to a terminal according to the transmission attribute information. By using the embodiments of the present invention, a scheduling suspension message/a scheduling start message may be sent to a terminal according to transmission attribute information, so as to schedule data resource of the radio communication network according to the transmission attribute information, thereby avoiding a situation in which the base station is congested, reducing scheduling time, and improving the data transmission efficiency of the radio communication network.
