Dynamic QoS Selection in 5G Service Provision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for providing services in 5G networks often result in wasted resources, traffic overload, long latencies, and reduced capacity due to the consistent use of highest quality of service (QoS) without considering user data plans, leading to poor network performance and user experience.
Innovation Solution
A computer-implemented method where nodes in a communications system request and determine allowed QoS and associated bit rates, enabling users to select appropriate video qualities based on data consumption, optimizing resource usage and network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the highest quality of service (QoS) is consistently applied for service provision, then the service quality is improved, but network resources are wasted and network capacity is reduced
Solution Approach 1:
The patent implements dynamic QoS selection where the network dynamically adjusts the quality of service level based on real-time conditions including user subscription plans, available network resources, and service requirements. Instead of consistently applying highest QoS, the system adapts QoS levels to match actual network capacity and user entitlements, thereby optimizing the balance between service quality and network resource utilization.
Solution Approach 2:
The patent changes the QoS parameter from a fixed highest level to a variable level that can take multiple values (e.g., high, medium, low) depending on network conditions and user subscriptions. This parameter change enables the system to adjust bit rates and service characteristics dynamically, resolving the contradiction between maintaining high service quality and preserving network capacity for other users.
2Reliability
If the highest quality of service (QoS) is consistently applied, then service quality is improved, but network latency increases and resources are wasted
Solution Approach 1:
The system dynamically adjusts QoS levels based on real-time network conditions, user subscriptions, and available resources. When network resources are constrained or user plans limit higher QoS, the system automatically selects appropriate lower QoS levels, reducing unnecessary latency and resource waste while maintaining acceptable service quality for all users.
Solution Approach 2:
The patent implements feedback mechanisms where the network monitors actual network conditions, user subscription status, and resource utilization. This feedback information is used to adjust QoS selections in real-time, ensuring that the highest possible quality service is provided without causing excessive latency or wasting resources when network conditions or user entitlements dictate otherwise.
3Ease of operation
If alternative QoS options are provided to users, then user experience is improved through informed selection, but network complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring and pre-calculating multiple QoS options and their associated bit rates before service activation. The network prepares QoS profiles in advance based on user subscription plans and network capabilities, so that when a user requests a service, the system can quickly present pre-defined options without complex real-time calculations, thereby improving user experience while limiting the increase in network complexity to manageable levels.
Data Source
AI summary
A method performed by a first node (111), for handling provision of a service to a device (130). The first node (111) receives (301) a request from a second node (112) operating in the communications system (100). The request requests an authorization for the provision of the service with a first quality of service (QoS), and for provision of the service with one or more alternative qualities of service (QoSs). The request further requests a bit rate associated to each of the first QoS and the one or more alternative QoSs. The first node (111) determines (302) one or more allowed QoSs, amongst the first QoS and the one or more alternative QoSs, and, for each allowed QoS, an associated bit rate. The first node (111) then sends (303) a response to the second node (112) to the received request. The response indicates the one or more allowed QoSs and the respectively associated bit rate.
