Radio Node Local QoS Profile Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, such as EPS/LTE networks, face performance degradation due to significant signaling required for updating Quality of Service (QoS) profiles, especially in scenarios like enterprise venues with frequent user entry and exit, leading to increased handovers and signaling overhead.
Innovation Solution
A method where a radio network node and wireless communication device manage traffic on an Access Stratum bearer by receiving requests with multiple QoS profiles and criteria, allowing local application of the appropriate QoS profile based on detected conditions, such as radio network node identity or service type, thereby reducing the need for extensive signaling updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If QoS profiles are updated through centralized core network nodes in existing wireless communication systems, then QoS management is maintained, but signaling overhead increases significantly especially in scenarios with frequent user entry and exit
Solution Approach 1:
The patent enables radio network nodes and wireless communication devices to locally store and apply multiple QoS profiles based on local criteria evaluation. Instead of centralized QoS management requiring continuous signaling updates, each node/device maintains a set of QoS profiles locally and autonomously selects the appropriate profile by evaluating local criteria such as service type, user identity, or network conditions. This localizes the QoS decision-making process, eliminating the need for frequent centralized updates and significantly reducing signaling overhead while maintaining reliable QoS management.
2Adaptability or versatility
If multiple QoS profiles are managed centrally with frequent updates to accommodate dynamic service requirements, then service adaptability is improved, but network performance degrades due to signaling overhead
Solution Approach 1:
The patent pre-configures multiple QoS profiles and associated criteria into radio network nodes and wireless communication devices during network setup or previous configuration phases. When dynamic service requirements arise, the nodes and devices autonomously evaluate local criteria against the pre-configured profiles and select the appropriate QoS profile without requiring real-time centralized updates. This preliminary configuration enables rapid service adaptation while avoiding the performance degradation caused by frequent signaling exchanges during operation.
3Measurement precision
If centralized QoS profile updates are performed for each user handover or service change, then QoS accuracy is maintained, but time consumption increases due to repeated signaling
Solution Approach 1:
The patent enables radio network nodes and wireless communication devices to self-serve QoS profile selection by autonomously evaluating local criteria and selecting appropriate QoS profiles from their local storage. Each node/device independently determines whether a QoS profile change is needed by comparing current service requirements against stored profiles and criteria, without requiring centralized verification or update signaling. This self-service mechanism maintains QoS accuracy through local decision-making while eliminating the time consumption associated with repeated centralized signaling for each handover or service change.

AI summary
A method and a radio network node (110) for handling traffic on an Access Stratum "AS" bearer are disclosed. The radio network node (110) receives, from a second core network node (122), an Access Stratum bearer request for setting up the Access Stratum bearer to carry traffic between a first core network node (121) and a wireless communication device (130), wherein the Access Stratum bearer request includes a first AS Quality of Service profile, a second AS Quality of Service profile, and at least one criterion for applying the first or second AS Quality of Service profile when processing the traffic. The radio network node (110) processes the traffic while applying the first or second AS Quality of Service profile based on whether or not one of the at least one criterion is fulfilled. Furthermore, corresponding methods, a first core network node (121), a second core network node (122) and a wireless communication device (130) for handling traffic on a common bearer are disclosed.
