Radio Communication Network Slice Selection via Group Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication systems lack a technology to appropriately select multiple network slices configured within the same APN, which is essential for managing diverse service requirements such as QoS and transmission delay in 5G networks.
Innovation Solution
A radio communication system that includes user equipment and call control apparatuses, which transmit access request signals with group specifying information and communication destination identifiers to establish communication paths through specific network slices, allowing for the appropriate selection of network slices based on service requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple network slices are configured in the same APN, then network service diversity and QoS differentiation are improved, but network slice selection capability is insufficient
Solution Approach 1:
The patent segments the network slice selection process by introducing group specifying information that divides communication apparatuses into multiple groups. Each group corresponds to a specific network slice, allowing the system to handle multiple slices within the same APN by routing requests to the appropriate group based on the specified information.
Solution Approach 2:
The patent introduces an intermediary mechanism where the call control apparatus receives access request signals containing group specifying information and communicates this to the appropriate communication apparatus in the corresponding group. This intermediary process enables proper network slice selection without requiring changes to the APN structure.
2Reliability
If network slices are divided by APN, then network resource isolation is improved, but flexibility for multiple slices per APN is reduced
Solution Approach 1:
The patent adds another dimension to network slice management by introducing group specifying information as a new layer of organization within the existing APN structure. Instead of relying solely on APN-based isolation, the system now uses group specifications to differentiate slices, allowing multiple slices to coexist within the same APN while maintaining resource isolation through the group dimension.

AI summary
A radio communication system includes user equipment, a call control apparatus, and a plurality of communication apparatuses, wherein each communication apparatus belongs to one of a plurality of groups, wherein the user equipment transmits, to the call control apparatus, a first access request signal including a group specifying information for specifying one group and a communication destination identifier, wherein the call control apparatus transmits, to the communication apparatus belonging to the one group specified by the group specifying information, a second access request signal including the communication destination identifier, and wherein the communication apparatus establishes a communication path between a communication destination indicated by the communication destination identifier included in the second access request signal and the user equipment.
