182Appendix C 911 Emergency Notification

A Public Safety Answering Point (PSAP) is an agency or group of agencies designated and authorized to receive and respond to 911 emergency calls requiring one or more public services: Police, Fire, Emergency Medical Service, or all three.

The OSN is required so that the OSN staff can prepare for the arrival of the emergency response team, and direct them to the location of the 911 caller when they arrive on site.

An emergency subscriber is the logical representation of a PSAP/OSN pair. When a user dials an emergency number (for example, 911), the call is mapped (using telephony routing rules) to the correct emergency subscriber for that subdomain. The routing rules for that emergency subscriber (created in the SIP Personal Agent) then instruct the SIP Application Module to both route the call to the correct PSAP and to send an Instant Message notification to the correct OSN subscriber. There is, therefore, a one-to-one relationship between a subdomain and the PSAP/OSN pair.

Setting up Instant Message Notifications

In order to properly set up IM notifications to an OSN subscriber, the domain administrator should divide the domain into geographical areas. A subdomain should then be created for each of these areas. If there is only one geographical area, no subdomains need to be created.

When a subscriber places an emergency call, the OSN subscriber assigned to the same subdomain (area) as the originator is notified. It is up to the administrator to decide how large or small to make the subdomain (area).
