Dynamic Network Slice Reliability for Human-Robot Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G and 5G-advanced communication systems provide static network slicing with high reliability as a 'static' attribute, leading to inefficient resource and energy consumption due to overprovisioning, as high reliability is not required at all times in Human-Robot-Interaction (HRI) or Human-Robot-Collaboration (HRC) scenarios.
Innovation Solution
A control entity determines operational conditions of user entities to dynamically configure a target reliability level for network slices, allowing adaptive reliability based on operational conditions, avoiding unnecessary overprovisioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static high reliability is provisioned for network slices, then reliability requirement is met, but resource and energy consumption increases due to overprovisioning
Solution Approach 1:
The patent applies dynamics by transitioning from static reliability provisioning to dynamic reliability configuration. The system continuously monitors operational conditions (such as traffic patterns, network load, and service requirements) and adjusts the reliability level of network slices in real-time. This allows the network to provision high reliability only when and where needed, rather than maintaining it constantly, thereby reducing unnecessary resource consumption while meeting reliability requirements when operational conditions demand it.
2Reliability
If redundant transmission paths are provided for high reliability, then packet delivery success rate improves, but network resource consumption increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the reliability parameter of network slices based on monitored operational conditions. Instead of fixing the reliability parameter at high levels always, the system modifies this parameter according to actual network state and service requirements. When operational conditions indicate stable network performance, the reliability parameter is reduced, allowing the network to use fewer redundant resources while maintaining acceptable packet delivery success rates.
3Reliability
If high reliability is provisioned continuously, then service performance is maintained, but cost related to access, control plane, and user plane increases
Solution Approach 1:
The patent applies periodic action through continuous monitoring and periodic adjustment of reliability levels. The system operates in cycles of monitoring operational conditions, evaluating whether high reliability is currently needed, and adjusting network slice configurations accordingly. This periodic evaluation allows the network to maintain high reliability during critical periods when operational conditions require it, while reducing reliability provisioning during normal periods, thereby lowering overall deployment costs.

AI summary
A control entity is provided for configuring a reliability level of a communication service in a network slice of a communication network, which supports a dynamic reliability of the communication service in the network slice relating to Human-Robot-Interaction (HRI) and/or Human-Robot-Collaboration (HRC) scenarios, which require the dynamic reliability. The control entity is configured to determine one or more operational conditions of one or more user entities, and to determine a target reliability level of the communication service in the network slice of the one or more user entities based on the determined one or more operational conditions. An application function is provided to configure the control entity the dreliability related information of one or more user entities, and a network entity is provided for enforcing the dynamic reliability level for the communication service in the network slice.
