Dynamic Network Slicing for Private Wireless and Cellular Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing private radio-based networks are costly and time-consuming to deploy, often under or overprovisioned, and struggle with dynamic changes in network requirements, while CSP-operated networks are overprovisioned and inefficient in meeting organization-specific needs.
Innovation Solution
Dynamic provisioning of provider-operated radio-based networks leveraging existing CSP infrastructure, allowing organizations to create ephemeral networks that scale up/down and integrate with private networks, using eSIMs and APIs for seamless transitions and intelligent network selection based on usage and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If private radio-based networks are deployed to meet organization-specific needs, then quality-of-service requirements can be met, but deployment cost and time increase
Solution Approach 1:
The patent introduces a network selection manager as an intermediary component that mediates between organizations and CSP-operated networks. This manager automatically selects appropriate networks and handles connectivity, eliminating the need for manual deployment and configuration of private radio-based networks while ensuring quality-of-service requirements are met.
Solution Approach 2:
The patent enables organizations to create virtual copies of CSP-operated networks through network slicing. Instead of deploying physical private networks, organizations can instantiate virtual network instances that replicate CSP infrastructure, allowing rapid deployment without actual network construction.
2Reliability
If private radio-based networks are deployed to meet organization-specific needs, then quality-of-service requirements can be met, but deployment cost increases
Solution Approach 1:
The patent makes CSP-operated networks universal by allowing multiple organizations to simultaneously use the same physical infrastructure through network slicing. A single CSP network can serve multiple organizations with different quality-of-service requirements, eliminating the need for each organization to deploy dedicated private networks and significantly reducing overall deployment costs.
Solution Approach 2:
Instead of organizations deploying expensive physical private networks, the patent enables them to create virtual copies of CSP networks through network slicing. These virtual instances replicate necessary network functions without requiring actual hardware deployment, dramatically reducing deployment costs while maintaining organization-specific quality-of-service requirements.
3Productivity
If CSP-operated networks are used to serve multiple organizations, then infrastructure utilization improves, but organization-specific needs are not met
Solution Approach 1:
The patent applies local quality by allowing each organization to receive customized network slices with specific quality-of-service characteristics tailored to their unique needs. While the underlying CSP infrastructure is shared, each organization's virtual network instance can be configured with appropriate bandwidth, latency, and reliability parameters localized to their specific requirements.
Solution Approach 2:
The patent enables CSP-operated networks to serve multiple organizations simultaneously through network slicing, making the infrastructure universal. Each organization gets a dedicated virtual network instance that isolates their traffic and configurations, ensuring that shared infrastructure can meet diverse organization-specific needs without interference.
4Ease of operation
If networks are provisioned statically to meet current needs, then configuration is simple, but dynamic changes in requirements cannot be accommodated
Solution Approach 1:
The patent introduces dynamic provisioning capabilities that allow network slices to be created, modified, and terminated automatically in response to changing organizational needs. The network selection manager can dynamically adjust network configurations, allocate resources, and modify connectivity settings without requiring manual reconfiguration, enabling the system to adapt to dynamic requirements while maintaining operational simplicity.

AI summary
Disclosed are various embodiments for managing simultaneous use of private wireless local area networks (WLANs) and cellular radio-based networks. In one embodiment, a user equipment (UE) device authenticates for access to a cellular radio-based network using a profile in an electronic subscriber identity module (eSIM). The UE device determines to transfer data via a WLAN rather than the cellular radio-based network. The UE device requests an access credential for the WLAN from the cellular radio-based network. The UE device uses the access credential to connect to the WLAN to transfer the data.
