Premises Emergency Routing via Identifier Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency communication systems face challenges in accurately determining the location of mobile device users making emergency calls, especially when the caller is not at their registered premises, leading to difficulties in connecting them with the appropriate emergency services.
Innovation Solution
A system and method that allows users to request emergency services for their premises, even if they are not present, by utilizing existing E911 infrastructure, where a premises-specific communication identifier is used to route the emergency call to the correct Public Safety Answering Point (PSAP), leveraging automatic number identification (ANI) and automatic location identification (ALI) services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mobile device location determination methods are used for emergency calls, then callers can be connected with emergency services, but accurate location determination becomes difficult when the caller is not at their registered premises
Solution Approach 1:
The system segments the emergency call routing process into two independent components: device location (where the caller is) and premises location (where the emergency occurred). By separating these location concepts and using premises-specific communication identifiers, the system can accurately route calls to the correct PSAP regardless of the caller's physical location.
Solution Approach 2:
The patent introduces an intermediary mechanism - the premises communication identifier (such as a premises telephone number) - that acts as a mediator between the caller and the PSAP. This intermediary identifier decouples the routing process from GPS/location data, allowing accurate premises identification even when the caller is mobile or away from the premises.
2Device complexity
If existing E911 infrastructure is used without changes, then system complexity is minimized, but the ability to accurately route calls when users are away from premises is limited
Solution Approach 1:
The patent makes the existing E911 infrastructure universal by enabling it to handle both traditional location-based calls and premises-based calls through the same ANI/ALI lookup process. The premises communication identifier is integrated into the existing telephone numbering system, allowing the infrastructure to serve multiple functions without modification.
Solution Approach 2:
The system leverages the existing self-service capabilities of the E911 infrastructure - specifically the automatic ANI/ALI lookup process - to resolve premises identification. By mapping premises communication identifiers to premises locations through the existing database lookup mechanism, the system achieves accurate routing without adding complex new infrastructure.
3Measurement precision
If premises-specific communication identifiers are implemented, then accurate routing to the correct premises is achieved, but the communication system requires additional identifier management
Solution Approach 1:
The patent merges the premises identification function with the existing telephone communication system by using premises telephone numbers as identifiers. This combining of premises identification with the familiar telephone numbering system avoids creating a separate, complex identifier management system while achieving accurate premises routing.

AI summary
Methods and systems for communicating with an emergency service are disclosed. A user device may receive a request to communicate with an emergency service associated with a premises. A communication identifier associated with the premises may be used to identify the user device regardless of the location of the user device to establish communication with the emergency service.
