Neutral Host Identifier Mapping for Private Network Emergency Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3GPP and GSMA standards primarily address Public Warning System (PWS) message transmission to users through Mobile Network Operators (MNOs), but fail to effectively direct warnings to User Equipment (UEs) connected via private/non-public communications networks, particularly in scenarios involving Citizens Broadband Radio System (CBRS) networks and Multi-Operator Core Networks (MOCN) gateways.
Innovation Solution
A system utilizing an Identifier Mapping Database (IMD) within a Private CBRS/Non-Public Network (PCNN) to map Mobile Network Operator (MNO) identifiers to PCNN identifiers, enabling the identification of target notification regions and routing of alert messages to specific UEs, with a Multi-Operator Core Network (MOCN) gateway facilitating message delivery across multiple MNOs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If PWS messages are transmitted using standard MNO infrastructure, then message delivery to public network users is reliable, but message delivery to private network users fails
Solution Approach 1:
The patent introduces a Neutral Host as an intermediary entity that bridges MNO and private network infrastructures. The Neutral Host receives PWS messages from MNOs and forwards them to UEs connected through private networks, enabling message delivery across network boundaries without requiring direct integration between MNO and private network systems
Solution Approach 2:
The Neutral Host is designed with multi-functionality to handle both MNO traffic and private network traffic. It can simultaneously serve as a gateway for public network messages while also managing private network identifier mappings and message routing, making the system adaptable to multiple network types
2Adaptability or versatility
If MOCN gateway is used to route communications, then multiple MNO connections are enabled, but identifier mapping complexity increases
Solution Approach 1:
The patent segments the identifier mapping function into separate components: the Neutral Host maintains mapping databases for different MNOs, and the MOCN gateway handles routing based on these mappings. This segmentation allows each component to focus on specific tasks, reducing overall system complexity while maintaining multi-MNO capability
Solution Approach 2:
The MOCN gateway acts as an intermediary between UEs and multiple MNO core networks. It translates between private network identifiers and MNO-specific identifiers, enabling seamless communication without requiring UEs to understand multiple MNO identifier systems simultaneously
3Adaptability or versatility
If private network identifiers are used for UE identification, then private network autonomy is maintained, but PWS message routing to target regions fails
Solution Approach 1:
The Neutral Host serves as an intermediary that translates between private network identifiers (which maintain network autonomy) and MNO identifiers (which contain geographic and routing information). This translation layer preserves private network independence while enabling accurate message routing to target notification areas
Solution Approach 2:
The system performs preliminary identifier mapping and target area determination at the Neutral Host before messages are forwarded to the MOCN gateway. This preliminary action ensures that routing information is resolved early in the message flow, preventing loss of target region information while maintaining private network identifier usage
