Network Slicing for Unauthorized UE Emergency Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern telecommunications systems face challenges in providing emergency communication services to unauthorized user equipment (UEs) that are not traceable or identifiable, while ensuring network security and capacity.
Innovation Solution
A 5G telecommunications system with a server that determines and manages network slices to enable unauthorized UEs to communicate with emergency service providers, while monitoring for malicious activity and mitigating threats to ensure service availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network allows unauthorized UEs to access emergency services, then emergency communication availability is improved, but network security and capacity are compromised
Solution Approach 1:
The network is divided into multiple slices, with specific slices designated for emergency services that can be accessed by unauthorized UEs. This segmentation isolates emergency traffic from general network traffic, allowing unauthorized access to emergency services without compromising overall network security. The network slice for emergency services acts as a dedicated, controlled environment that maintains security boundaries while providing necessary access.
Solution Approach 2:
A server acts as an intermediary between unauthorized UEs and the emergency service infrastructure. This server determines appropriate network slices for unauthorized devices, managing their access centrally. The intermediary controls and monitors connections, enabling emergency communication while maintaining security through centralized management and oversight of unauthorized device access patterns.
2Adaptability or versatility
If the network provides services to unauthorized UEs, then network accessibility is improved, but network capacity is consumed
Solution Approach 1:
Network resources are segmented into dedicated slices for emergency services and general services. Unauthorized UEs are routed to specific emergency service slices that have predetermined resource allocations. This ensures that capacity consumption by unauthorized devices is confined to specific slices rather than impacting the entire network, maintaining overall capacity while providing accessibility.
Solution Approach 2:
The system dynamically changes network parameters such as slice selection, resource allocation, and access permissions based on device authorization status and service type. Unauthorized UEs are assigned specific network slice parameters that control their resource usage, allowing the network to adapt resource distribution in real-time to balance accessibility with capacity management.
3Object-affected harmful factors
If the network monitors all UEs for malicious activity, then network security is improved, but system complexity increases
Solution Approach 1:
Security monitoring is segmented and focused specifically on traffic within emergency service network slices rather than monitoring all network traffic uniformly. The system monitors unauthorized UE behavior patterns within the context of emergency communications, reducing the complexity burden by concentrating monitoring efforts where they are most critical while leveraging the inherent structure of network slicing to simplify implementation.

AI summary
Techniques for determining a network slice for a communication session associated with user equipment (UE) are described herein. A fifth generation telecommunications network can implement a server to determine a network slice that enables an unauthorized UE to communicate with an emergency service provider. The server can determine that the UE is not associated with a mobile network operator or is otherwise untraceable, and enable a communication session between the UE and emergency service provider. The server can detect malicious activity in the network slice and perform actions to mitigate the malicious activity associated with the network slice.
