Network Slice Group Information for Device-Specific Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient mechanisms for managing network slice group information, particularly in scenarios involving wireless devices that support or do not support specific network slices, leading to suboptimal network resource allocation and user experience.
Innovation Solution
A method for a core network device to receive and send messages indicating network slice group information, including supported and unsupported network slices, along with their identifiers and coverage areas, to facilitate informed network slice group management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network slice group information is not provided to wireless devices, then device complexity is reduced, but network resource allocation efficiency deteriorates
Solution Approach 1:
The patent segments network slice information into group-based structures (network slice group information including slice group ID, slice priority, and slice status). This segmentation allows devices to process information in organized groups rather than individual slices, improving allocation efficiency while managing complexity through structured data organization.
Solution Approach 2:
The patent introduces network slice group information as an intermediary layer between the core network and wireless devices. This intermediary structure (comprising slice group ID, priority, and status fields) mediates the communication, enabling efficient resource allocation without requiring devices to handle complex individual slice configurations directly.
2Productivity
If comprehensive network slice information is provided to all devices, then network resource allocation is optimized, but information loss increases due to unnecessary data transmission to devices that do not support certain slices
Solution Approach 1:
The patent applies local quality by providing tailored network slice group information based on device capabilities. Devices receive slice group information corresponding only to slices they support, while the network maintains comprehensive slice configurations. This ensures optimized allocation for each device without transmitting unnecessary information about unsupported slices.
Solution Approach 2:
The patent changes the parameter of information provision from static comprehensive data to dynamic device-specific data. The network slice group information is adjusted based on device support capabilities, transforming the information delivery from a one-size-fits-all approach to a customized approach that prevents information loss while maintaining allocation optimization.
3Ease of operation
If network slice group information is transmitted to wireless devices, then user experience is improved, but loss of time occurs due to additional signaling overhead
Solution Approach 1:
The patent implements preliminary action by pre-configuring network slice group information (including slice group ID, priority, and status) before actual network slice activation. This allows devices to have slice group information readily available, improving user experience through faster slice selection and activation while reducing the need for repeated signaling exchanges during operation.

AI summary
A core network device receives, from a wireless device, a first message indicating a request for network slice group information. The core network device sends, to the wireless device, a second message comprising the network slice group information, wherein the network slice group information indicates that a first network slice group comprises at least one first network slice.
