Access Stratum Group Segmentation for V2X QoS Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in providing consistent group service quality for terminal devices engaged in the same application group, particularly in V2X applications, due to inconsistent Quality of Service (QoS) and inefficient use of radio resources, leading to unstable operations and resource inefficiencies.
Innovation Solution
The method involves creating an access stratum group with subgroups based on predetermined criteria such as sidelink resource allocation, network coverage, physical position, and radio quality, ensuring consistent access configuration and QoS across terminal devices within a subgroup, and dynamically adjusting subgroups as needed to maintain optimal resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If terminal devices in the same application group are handled independently at the access stratum layer, then individual device flexibility is maintained, but group service quality consistency deteriorates
Solution Approach 1:
The patent segments terminal devices into different access stratum groups based on their application group memberships. Each access stratum group is configured with consistent access parameters and QoS settings, ensuring service quality consistency within groups while maintaining independence between different device groups. This segmentation resolves the contradiction by organizing devices into manageable units with uniform characteristics.
Solution Approach 2:
The patent applies local quality by configuring different access stratum parameters specifically for each access stratum group based on the service requirements of the corresponding application group. Each group receives tailored QoS parameters, resource allocation settings, and access configurations that match its specific needs, rather than applying uniform settings to all devices. This enables consistent service quality within each group while adapting to diverse application requirements.
2Reliability
If consistent access configuration is applied to all terminal devices in an application group, then group service quality is improved, but radio resource efficiency deteriorates
Solution Approach 1:
The patent further segments access stratum groups into subgroups based on additional criteria such as radio quality, coverage type, or specific service requirements. This finer-grained segmentation allows consistent configuration within subgroups while reducing the number of devices sharing the same resource allocation, thereby improving radio resource efficiency. Devices with similar characteristics are grouped together, avoiding wasteful over-provisioning for devices with lower requirements.
Solution Approach 2:
The patent dynamically adjusts access stratum parameters such as QoS profiles, resource block allocations, and power settings based on the specific characteristics of each subgroup. By changing parameters to match actual device needs and network conditions, the system maintains consistent service quality within subgroups while optimizing radio resource utilization across the entire network, preventing both over-provisioning and under-provisioning.

AI summary
The present disclosure provides a method for a communication system with group service. The method includes: creating an access stratum group including at least one terminal device. The at least one terminal device is included in a same application group for supporting an application relating to the at least one terminal device. It is an advantage that the terminal devices engaged in the same application group could be handled more consistently in an access stratum layer in the communication system. The group service quality may be further improved.
