Caller ID Message Format Extension for GPS Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Analog Caller ID standards are limited to information associated with the initial establishment of a communication, failing to transmit data not related to this, such as GPS coordinates, which restricts the capabilities of systems relying on PSTN and analog Caller ID, especially for mobile and VOIP devices, while adhering to FCC regulations.
Innovation Solution
A new message format under existing analog Caller ID standards is introduced, allowing additional data like GPS coordinates to be inserted into Caller ID messages, enabling devices like PBX and contact centers to route or display this information effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If analog Caller ID standards are used to transmit information, then the system can send data related to initial call establishment, but the system cannot transmit additional data such as GPS coordinates or other non-initial communication information
Solution Approach 1:
The Caller ID message is segmented into multiple data fields, with existing fields for initial call establishment information and new fields added for additional data types such as GPS coordinates. This allows the message to carry both traditional and extended information without disrupting the core functionality.
Solution Approach 2:
The patent extends the Caller ID message format by adding new dimensions of data transmission capability. New message format fields are introduced that can carry additional information types (GPS, routing data, etc.) beyond the traditional initial call establishment parameters, effectively increasing the message capacity without changing the fundamental analog transmission mechanism.
2Reliability
If a database look-up is used to map Caller ID to location information, then PSTN land line location mapping is reliable, but the system fails to work for mobile devices and VOIP telephones that can register from different locations
Solution Approach 1:
The patent introduces an intermediary mechanism where the Caller ID message itself carries location-related data (such as GPS coordinates) directly within the message format. This eliminates the need for external database look-ups and enables direct transmission of location information from the calling device, working reliably across PSTN, mobile, and VOIP platforms.
Solution Approach 2:
The message format parameters are changed to include new fields that can carry location information. By modifying the Caller ID message structure to accommodate additional parameters (GPS coordinates, location data), the system can reliably transmit location information for any device type without relying on device-specific database mappings.
3Loss of information
If FCC regulations are adhered to regarding toll charges, then the system can transmit initial call establishment information freely, but the system cannot transmit additional information such as GPS coordinates without incurring toll charges
Solution Approach 1:
The enhanced Caller ID message format is designed to be universal, carrying both traditional initial call establishment information and additional data types (GPS coordinates, routing information) within the same message structure. This multi-functional approach allows the system to transmit diverse information types through a single standardized mechanism, maximizing data transmission capability while adhering to FCC regulations.
Data Source
AI summary
A communication system receives data that does not pertain to an attempted initial establishment of a communication. The communication system uses a new message format under an existing analog Caller ID standard. The communication system inserts the data (which can be in addition to existing Caller ID data) into a Caller ID message that uses the new message format. The communication system then sends the Caller ID message to a communication device/Private Branch Exchange (PBX)/contact center that can interpret the new message format. The communication device/PBX/contact center can use the data to further route the communication to a specific telephone and/or can use the data to display information such as Global Positioning System (GPS) coordinates of a cell phone. The data can enhance the capabilities of devices and systems that currently work under the Public Switched Telephone Network (PSTN).
