gNodeB Priority Adjustment for 5G Standalone QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network adoption of new 5G standalone services is delayed due to subscriber equipment limitations, leading to diminished user satisfaction and wasted investment in network technologies, as older devices may not support new spectrum allocations or require simultaneous support of multiple network technologies.
Innovation Solution
A gNodeB prioritizes 5G standalone traffic by adjusting the priority of user equipment requests, mapping 4G QoS class identifiers to 5G QoS class identifiers, and dynamically monitoring and adjusting priorities to maintain quality of service, especially for 5G standalone communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network supports multiple network technologies simultaneously to accommodate older devices, then device compatibility is improved, but service adoption speed deteriorates
Solution Approach 1:
The patent applies local quality by differentiating QoS treatment for different device types. 5G SA-capable devices receive prioritized service with higher quality-of-service class identifiers, while 5G NSA devices receive standard treatment. This localized differentiation allows the network to optimize for new devices without compromising compatibility with older devices, thereby resolving the contradiction between adaptability and adoption speed.
2Productivity
If the network prioritizes new 5G standalone services, then service adoption speed is improved, but quality of service for older devices deteriorates
Solution Approach 1:
The patent employs parameter changes by dynamically adjusting the quality-of-service class identifier (QCI) based on device capability. When a device is identified as 5G SA-capable, the network assigns a prioritized QCI value that ensures high QoS. This parameter adjustment allows the network to improve adoption speed for new services while maintaining reliable QoS for all devices through capability-based differentiation.
3Ease of operation
If the network assigns equal priority to all user equipment, then ease of operation is improved, but quality of service for 5G standalone services deteriorates
Solution Approach 1:
The patent implements dynamics by making priority assignment adaptive rather than static. The network dynamically determines device capabilities and adjusts QoS parameters accordingly. This dynamic approach maintains operational simplicity through automated capability detection while achieving differentiated QoS that prioritizes 5G standalone services, resolving the contradiction between ease of operation and service quality.

AI summary
Adjusting priority of 5G standalone traffic at a gNodeB can include detecting, at a gNodeB of a mobility network, a connection with a user equipment and examining, by the gNodeB, a connection request associated with the user equipment. The connection request can include bearer information. The gNodeB can determine if the user equipment is requesting 5G standalone services. In response to a determination that the user equipment is requesting the 5G standalone communications, the gNodeB can adjust a priority to be used for the communications associated with the user equipment to obtain an adjusted priority for a connection associated with the 5G standalone communications. The gNodeB also can tunnel communications between the gNodeB and a 5G core of the mobility network. The communications associated with the 5G standalone communications can be provided by the mobility network at the adjusted priority.
