Mobile Switching Center Automatic Reverse 911 Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reverse 911 systems do not automatically register mobile devices, requiring manual user registration and failing to account for the user's current location during emergencies, leading to missed notifications when users are away from their registered location.
Innovation Solution
A method and system that automatically provide contact information of a mobile device to a reverse 911 database by receiving a registration request at a mobile switching center, determining if the device is new to a wireless sub-network, and passing the contact information to the database for inclusion, ensuring the user receives notifications at their current location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual user registration is required for mobile devices in reverse 911 systems, then system complexity is reduced, but user convenience and registration completeness deteriorate
Solution Approach 1:
The mobile device automatically performs registration with the reverse 911 system without user intervention. The device's processor executes instructions to transmit contact information and location data to the reverse 911 database, enabling the system to serve itself by automatically enrolling new mobile devices as they connect to the wireless network.
Solution Approach 2:
The system performs registration actions in advance by automatically enrolling mobile devices when they first connect to the wireless network. This preliminary automatic registration ensures contact information is captured before emergencies occur, eliminating the need for users to manually register later.
2Reliability
If mobile devices are automatically registered with reverse 911 system, then registration completeness is improved, but system complexity increases
Solution Approach 1:
The mobile device's existing processor and communication capabilities are utilized for dual purposes: normal cellular operations and automatic reverse 911 registration. This multi-functionality allows the device to perform self-registration without adding separate dedicated hardware, reducing the complexity increase while improving registration completeness.
Solution Approach 2:
The wireless network infrastructure acts as an intermediary that facilitates automatic registration. When a mobile device connects to the network, the system intercepts connection data and automatically transmits it to the reverse 911 database, using the existing network infrastructure to bridge the registration process without requiring complex direct device-to-database communication protocols.
3Measurement precision
If real-time location updates are implemented for mobile devices, then notification accuracy is improved, but data transmission requirements increase
Solution Approach 1:
Instead of continuous real-time location tracking, the system updates mobile device location information periodically when the device checks in with the wireless network or when connection parameters change. This periodic updating maintains reasonable location accuracy while significantly reducing data transmission volume compared to continuous tracking.

AI summary
In one embodiment, when a mobile device is powered on, a mobile switching center acquires the contact information, such as, but not limited to, a phone number and the physical location associated with the mobile device. If the mobile device is a new device to the area, the contact information of the mobile device is passed to a reverse 911 database in order for a user of the mobile device to receive local alert messages transmitted by a reverse 911 system.
