Base Station Scheduling for Non-GBR Bearer QoS in 5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, particularly in Fixed Wireless Access (FWA) networks, communication devices in weak electric field areas consume excessive resources, leading to unsatisfactory service quality for other devices sharing the same base station resources, and non-GBR bearers without guaranteed data rates cause inefficient resource allocation.
Innovation Solution
A base station method that schedules communication devices with non-GBR bearers by considering service characteristics and resource constraints, prioritizing resource allocation based on QCI, ARP, and SPID information to ensure a predetermined bit rate for selected non-GBR bearers, similar to GBR bearers for real-time services, and allocates resources efficiently within constrained physical limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resources are allocated to communication devices in weak electric field areas to maintain service quality, then service quality for those devices is improved, but resource availability for other devices sharing the base station decreases
Solution Approach 1:
The patent changes the parameter of resource allocation by introducing dynamic classification of non-GBR bearers into guaranteed and non-guaranteed groups based on QoS requirements. This allows the system to adjust resource allocation parameters selectively - guaranteeing resources for critical services while allowing flexibility for non-critical services, thereby resolving the contradiction between maintaining service quality and preserving resource availability.
Solution Approach 2:
The patent applies local quality by differentiating resource allocation strategies for different types of services and devices. Instead of uniform resource allocation, the system applies specific allocation rules to GBR bearers, guaranteed non-GBR bearers, and non-guaranteed non-GBR bearers based on their local QoS requirements and channel conditions, optimizing overall system performance.
2Reliability
If non-GBR bearers are allocated resources indiscriminately to maintain data rate, then service quality standard is met, but physical resources are wasted and other services suffer
Solution Approach 1:
The patent introduces dynamics into the resource allocation system by making the classification of non-GBR bearers flexible and adaptive. The system can dynamically adjust which non-GBR bearers receive guaranteed resources based on current network conditions, QoS requirements, and available capacity, rather than using static allocation rules. This resolves the contradiction by enabling the system to meet service quality standards only when necessary and efficient.

AI summary
The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate beyond a 4G communication system such as LTE. The present invention relates to a method for guaranteeing quality of service in a wireless communication system. More particularly, a method of a base station according to an embodiment of the present invention comprises the steps of: identifying at least one non-Guaranteed bit rate (GBR) bearer configured for an arbitrary communication device; determining whether to guarantee a specific bit rate to the non-GBR bearer, on the basis of at least one of QoS class identifier (QCI) information, allocation and retention priority (ARP) information, and subscriber profile identifier (SPID), which are received from a core network node for the non-GBR bearer; and performing scheduling for the non-GBR bearer on the basis of the determination.
