Network Slice Restriction Management in User Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, existing technologies lack effective methods to manage and restrict network slice usage based on specific conditions, leading to inefficient resource allocation and unnecessary access to restricted slices.
Innovation Solution
A communication control method that involves receiving network slice restriction information from a base station or core network apparatus, which includes an identifier and information about the restrictive conditions, allowing user equipment to appropriately judge and avoid using restricted network slices, thereby optimizing resource utilization.

Engineering Contradiction Analysis
1Productivity
If network slice restriction information is not provided to user equipment, then user equipment can freely access any network slice, but this leads to inefficient resource allocation and unnecessary access to restricted slices
Solution Approach 1:
The base station performs preliminary actions by determining restrictive conditions for network slices before user equipment attempts access. The base station proactively identifies which slices should be restricted and communicates these restrictions to user equipment in advance, preventing unnecessary access attempts and optimizing resource allocation before conflicts occur.
Solution Approach 2:
The system implements feedback by transmitting network slice restriction information from the base station to user equipment. This feedback mechanism allows user equipment to adjust its behavior based on current network conditions and slice availability, creating a closed-loop control system that optimizes resource allocation dynamically.
2Reliability
If network slice restriction information is transmitted to user equipment, then unnecessary access to restricted slices is prevented, but this requires additional signaling overhead and network management complexity
Solution Approach 1:
The patent extracts only the essential restriction information needed for user equipment to make access decisions. Instead of transmitting complete network slice configurations or detailed policy information, the system extracts and transmits only the critical restrictive conditions, reducing signaling overhead while maintaining access control reliability.
3Ease of operation
If user equipment freely accesses all network slices without restriction information, then access flexibility is maintained, but resource allocation efficiency deteriorates due to unnecessary access attempts
Solution Approach 1:
The system implements dynamic access control where user equipment can freely access slices when no restrictions are applied, but automatically adjusts behavior when restriction information is received. The access control mechanism transitions from static (always free or always restricted) to dynamic (free when allowed, restricted when prohibited), maintaining flexibility while optimizing resource allocation based on current network conditions.

AI summary
A user equipment includes a step of receiving network slice restriction information related to a network slice to be provided with a restrictive condition from a base station or a core network apparatus. The restrictive condition is a condition for restricting use of the network slice. The network slice restriction information includes an identifier for identifying the network slice and information indicating the restrictive condition.
