Network Slice Instantiation for Secure Wearable Data Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable smart devices face challenges in securely transmitting and storing sensitive health data, as they may not always have access to secure 3GPP networks, and using less secure wireless methods like Wi-Fi can compromise data security.
Innovation Solution
The implementation of an end-to-end network slice within a user endpoint device, configured with specific network service metrics, allows for secure data transmission over a predefined combination of network services, using virtual network functions and a radio transceiver to connect to the core network when available, and storing data locally when not connected, ensuring secure storage and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wearable smart devices transmit health data over less secure wireless networks like Wi-Fi, then data transmission continuity is improved, but data security is compromised
Solution Approach 1:
The network is segmented into multiple slices with different security characteristics. A first network slice provides secure transmission for available data, while a second network slice provides isolated storage for sensitive data, allowing the device to maintain both transmission continuity and security
Solution Approach 2:
The patent introduces an intermediary storage mechanism (second network slice) that acts as a buffer between data collection and transmission. This intermediary allows data to be stored securely when secure networks are unavailable, decoupling transmission continuity from security requirements
2Reliability
If wearable smart devices store sensitive data locally without secure network connection, then data security is maintained, but data transmission capability is lost
Solution Approach 1:
The system dynamically switches between different network slices based on network availability and security requirements. When secure networks are available, data is transmitted via the first network slice; when unavailable, data is stored in the second network slice, creating a dynamic adaptation to environmental conditions
Solution Approach 2:
The patent changes the operational parameters of network slices based on connection status. The first network slice is activated for transmission when secure networks are available, while the second network slice is activated for secure storage when networks are unavailable, allowing the system to optimize both security and transmission capability under different conditions
3Reliability
If wearable smart devices establish end-to-end network slices with specific service metrics, then data transmission security is improved, but device complexity increases
Solution Approach 1:
The network slice architecture provides multi-functionality within a single framework. The same slice mechanism handles both secure transmission and isolated storage functions, reducing overall system complexity compared to implementing separate systems for each function

AI summary
In one example, the present disclosure describes a device, computer-readable medium, and method for instantiating intelligent service delivery parameters within protected hardware. For instance, in one example, a method includes instantiating within a user endpoint device an end-to-end slice of a communications network, wherein the slice is configured to carry data over the communications network subject to a predefined combination of network service metrics, transmitting user data from the user endpoint device to the communications network via the slice when the user endpoint device is able to establish a radio connection to the communications network, and storing the user data locally in the user endpoint device when the user endpoint device is unable to establish a radio connection to the communications network.
