Location-Based PSAP URI Acquisition via Intermediary Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IP-based communication networks do not provide Uniform Resource Identifier (URI) information of Public Safety Access Points (PSAPs) relative to a requesting entity's location, posing risks in emergency situations.
Innovation Solution
A communication unit in the network requests ancillary information, such as a PSAP's URI, by sending a location-based request to a trusted information server, which processes and responds with the relevant information, ensuring accuracy and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IP-based communication networks operate without location-based ancillary information services, then network simplicity and lower infrastructure costs are maintained, but safety and reliability in emergency situations deteriorate
Solution Approach 1:
The patent introduces an information server as an intermediary component that mediates between communication units and location-based services. The server receives location information from communication units, queries a database for ancillary information (such as PSAP URIs), and returns the relevant information. This intermediary approach enables location-based safety services without requiring complex integration into the core network infrastructure, thus improving reliability while minimizing added complexity.
2Measurement precision
If location-based ancillary information services are implemented, then accuracy and reliability of emergency service connection are improved, but information processing requirements and system complexity increase
Solution Approach 1:
The patent implements a database that pre-stores ancillary information (such as PSAP URIs, emergency contact details, and location-based service data) before it is needed. When a communication unit requests location-based ancillary information, the information server simply queries this pre-populated database rather than performing complex real-time calculations or data gathering. This preliminary preparation of information significantly reduces processing complexity while maintaining high accuracy.
Data Source
AI summary
A technique for providing information relative to an entity's location to an entity in a communication network. A request for information is generated by a first entity wherein the request contains a location of the first entity. The request is then forwarded to a second entity which illustratively is a trusted source in the communication network. The second entity receives the request and identifies the requested information using the location information contained in the request. A notification containing the identified information is then generated by the second entity and forwarded to the first entity. The first entity receives the notification and processes it accordingly.
