Wireless Access Node QoS Priority Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless networks, particularly in LTE systems, there is a mismatch between access control and admission control prioritization, leading to inefficient resource allocation and poor quality of experience for prioritized connections, as access priority is not aligned with Quality of Service (QoS) profiles until late in the process, causing temporary resource waste and suboptimal service delivery.
Innovation Solution
A method where a wireless network access node receives Quality of Service (QoS) information from a mobility management node and transmits access priority information to the wireless device, aligning access and admission control priorities with the authorized QoS profiles, ensuring that resources are allocated based on the correct priority levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If access control uses hardcoded access classes in USIM card, then access priority is determined early in the process, but it does not align with authorized QoS profiles, causing mismatch with admission control priorities
Solution Approach 1:
The patent applies preliminary action by having the wireless device obtain access priority information from the network before attempting access control. The network node provides the device with priority information that reflects the authorized QoS profile in advance, so that when access control is performed, the device can use the correct priority that aligns with admission control requirements, rather than relying on hardcoded USIM classes.
2Productivity
If access priority is not aligned with QoS profiles until late in the process, then resource allocation can be optimized, but temporary resource waste occurs during the mismatch period
Solution Approach 1:
The patent implements feedback by having the network node provide access priority information to the wireless device based on the authorized QoS profile. The device uses this feedback information to adjust its access control behavior, ensuring that the priority used in access control matches the priority that will be used in admission control, thereby eliminating temporary resource waste.
3Adaptability or versatility
If access control and admission control use different priority mechanisms, then flexibility in handling different access scenarios is improved, but consistency in resource allocation is compromised
Solution Approach 1:
The patent applies universality by creating a unified priority mechanism where the access priority information provided to the device serves both access control and admission control functions. The network node determines a single priority based on the QoS profile that is then used consistently across both control mechanisms, eliminating the inconsistency between different priority mechanisms while maintaining flexibility through QoS-based priority determination.
