The primary mission of IADC is to provide timely urgent alert information to the public via their Mobile Devices.
One of the key capabilities of the IADC system is the ability to send alerts and message with polygons and coordinates to a Cell Broadcast Center (CBC), so that messages will be sent to a specific area. This includes predefined areas/polygons and ad-hoc polygons.
However some CBC vendors do not support the ability to receive multiple polygons and coordinates (location) and support only proprietary interfaces. This prevents sending polygons to the CBC and limits the capabilities of the IADC connecting with the CBC.
The CMSP Gateway maps the designated alerting areas into the associated radio coverage area (set of cell sites). The CMSP Gateway constructs a short broadcast message based on the received alert message, and transmits the short message to the CBC, with the associated radio coverage area.
The main functions of the CMSP Gateway are:
- Process IADC messages
- Validate format
- Map the alert area which the IADC sends to the CBC into the associated set of cells.
- Send message to CBC for Delivery
Test communication with IADC server
- Overcome CBC limitation of receiving coordinates
- Polygons can be with unlimited number of coordinates (points)
- Allow for multi polygons
- Mobile operators do not have to expose their cell data to external entity
- Faster performance to sending polygons
- Converts CAP message to CBC format
- Support of standard and proprietary CBC interfaces, allows connection to virtually all CBC vendors
