Innovation Solution
A CBRS wireless network hub manages access to a CBRS private wireless network by associating with a CBRS device, generating or obtaining an eSIM using a one-time public key, implementing dual software stacks for cellular and CBRS communication, and employing a traffic scheduler to reduce interference among multiple nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If Wi-Fi bands are used for wireless communication, then coverage area is large, but interference and congestion increase
Solution Approach 1:
The patent introduces a CBRS wireless network hub as an intermediary system that bridges cellular networks and private wireless networks. This hub manages spectrum access and coordinates communication between multiple CBRS wireless nodes, enabling devices to access spectrum efficiently while reducing interference through centralized control and coordinated spectrum sharing
Solution Approach 2:
The patent changes the operational parameters by transitioning from traditional Wi-Fi frequency bands to CBRS spectrum (3.5 GHz band), which offers different propagation characteristics and interference patterns. The system dynamically allocates spectrum resources and adjusts transmission parameters to optimize performance while minimizing interference
2Productivity
If multiple CBRS wireless nodes connect to the private wireless network, then network capacity increases, but interference between nodes increases
Solution Approach 1:
The CBRS wireless network hub implements feedback mechanisms to monitor spectrum usage and interference levels from multiple CBRS wireless nodes. Based on this feedback, the hub dynamically adjusts spectrum allocation, transmission power levels, and scheduling decisions to optimize network capacity while minimizing inter-node interference
Solution Approach 2:
The system dynamically allocates spectrum resources among multiple CBRS wireless nodes based on real-time conditions. The hub can dynamically adjust which nodes access the spectrum at any given time, changing allocation decisions based on traffic patterns, interference levels, and available spectrum, thereby maximizing network capacity while controlling interference
3Reliability
If eSIM credentials are used for secure authentication, then security improves, but device complexity increases
Solution Approach 1:
The patent uses eSIM (embedded SIM) technology that embeds authentication credentials directly into the device's hardware or storage, eliminating the need for physical SIM cards. This copying of authentication functionality into the device's inherent storage provides secure authentication while simplifying the user experience and reducing physical component complexity

AI summary
This Application describes managing access to a Citizens Band Radio Service (CBRS) private wireless network that is maintained by a CBRS wireless network hub. A CBRS wireless node associates with the CBRS wireless network hub and obtains an electronic subscriber identity module (eSIM) to connect to the CBRS private wireless network. The eSIM is generated by the CBRS wireless network hub or by a cloud-network server using a one-time public key (otPK) obtained from the CBRS wireless node. The CBRS wireless node can authenticate before obtaining the eSIM based on i) having a common cloud-network service account or a different cloud-network service account of the cloud-network server as the CBRS wireless network hub, or ii) by using a mutual authentication procedure. The eSIM can be revoked and stored at the CBRS wireless network hub for subsequent re-use with the CBRS wireless node.
