Emergency Alerts: Customization of alerts #5

Open dsilhavy opened 1 month ago

Describtion

Our rt-mbms-tx-for-qrd-and-crd transmitter is able to transmit SIB12 messages to trigger an emergency alert. A detailed documentation on how to set this up is available here: https://5g-mag.github.io/Getting-Started/pages/emergency-alerts/tutorials/end-to-end.html

Feature Request

Right now we are triggering default alerts such as tsunami a or earthquake warnings. It would be nice to enable triggering "custom alerts" with a custom alert message.

The content of the SIB 12 message is currently hardcoded and looks like this:

sib12 =
{
    message_identifier = 0x1102;
    serial_number = 0x3000;
    data_coding_scheme = 01;
    warning_msg_segment_type = "lastSegment";
    warning_msg_segment_num = 0;
    warning_msg_segment_r9 = "01C576597E2EBBC7F950A8D168341A8D46A3D168341A8D46A3D168341A8D46A3D168341A8D46A3D168341A8D46A3D168341A8D46A3D168341A8D46A3D168341A8D46A3D168341A8D46A3D168341A8D46A3D1000A";
};

We need to evaluate what needs to be changed to trigger a custom alert with a custom message.
