Database Access Provider for VoIP E-911 Location Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for providing location information during E-911 calls from VoIP telephones are expensive to maintain, complex, and require dedicated trunks for database communication, making them costly and difficult to manage.
Innovation Solution
A network configuration using a calling name database or third-party database with an interactive voice response system to store and retrieve location information, allowing public-safety answering points to request and display location information during E-911 calls, reducing the need for dedicated trunks and simplifying database management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a VoIP positioning center database is used to store and provide location information for E-911 calls, then location information can be provided to public-safety answering points, but the system becomes expensive to maintain and requires dedicated trunks for database communication
Solution Approach 1:
The patent introduces a database access provider as an intermediary component that sits between the public safety network and the location information database. This mediator handles all database communication requests, manages the connection pool, and formats data appropriately, thereby reducing the complexity for individual PSAPs and eliminating the need for each to maintain direct dedicated trunk connections to the database.
Solution Approach 2:
The database access provider serves multiple PSAPs simultaneously through a single infrastructure, providing universal access to location information services. This multi-functional component handles querying, data formatting, and connection management for multiple clients, reducing overall system complexity and eliminating the need for separate dedicated trunks for each PSAP.
2Reliability
If dedicated trunks are used for database communication, then reliable data transmission is ensured, but the cost of maintaining the system increases significantly
Solution Approach 1:
The patent merges multiple separate communication channels into a single shared infrastructure by implementing a database access provider that consolidates all database communication requests from multiple PSAPs through one connection pool, thereby reducing the number of dedicated trunks needed while maintaining reliable data transmission.
Solution Approach 2:
Instead of creating separate physical dedicated trunk connections for each PSAP, the system creates virtual copies of connection pathways through the database access provider, which manages a pool of connections that serve multiple clients, reducing physical infrastructure costs while maintaining transmission reliability.
3Loss of information
If a VoIP positioning center is implemented, then location information can be retrieved during E-911 calls, but the system becomes difficult to manage and operate
Solution Approach 1:
The database access provider acts as an intermediary that abstracts the complexity of database management from PSAP operators. It handles connection management, data formatting, and query processing automatically, making the system easier to operate while ensuring location information is reliably retrieved and delivered during E-911 calls.
Solution Approach 2:
The database access provider implements self-service capabilities by automatically managing its own connection pool, handling query routing, and formatting responses without requiring manual intervention from PSAP operators, thereby simplifying system operation and maintenance.

AI summary
A system and method for communicating location information of a VoIP subscriber to a public-safety answering point may include receiving an E-911 telephone call from a VoIP telephone. Location information associated with the VoIP telephone stored in a database may be requested. The location information may be received in a signal formatted substantially the same as a signal format for communicating caller identification information. The location information may be displayed at a public-safety answering point. In one embodiment, the location information may be displayed on a video display.
