Abstract
Group-based emergency notifications and acknowledgments are managed via a radio controller. A request to transmit an emergency notification with acknowledgment to an identified target group of subscriber devices is received at the radio controller from a requesting device. The radio controller identifies one or more base stations actively serving subscriber devices associated with the identified target group and identifies, for each of the identified one or more base stations, active channels including one or more of a control channel associated with the base station and active voice or data channels associated with the base station. The radio controller causes an emergency notification outbound signaling packet (OSP), requesting individual acknowledgment and identifying the target group of subscriber devices, to be broadcast on the identified active channels at the identified one or more base stations. Acknowledgments are forwarded back to one of the requesting device and a dispatch console.
