Emergency group call over eMBMS

In the event of an emergency, inter-agency collaboration is critical to prevent incidents that can further endanger the public. Our paper proposes the emergency group call over Long Term Evolution (LTE) Evolved Multimedia Broadcast Multicast Service (eMBMS). Current LTE eMBMS specification provides a mechanism for downlink video content delivery and file transmission only. We worked on a novel design for enhancing the current emergency group call network based on the eMBMS solution. Following features are technically further enhanced in our work to provide adequate emergency group services: Multimedia Broadcast Single Frequency Network (MBSFN) architecture, privacy, MBSFN area allocation, service continuity and reduced eMBMS call setup time.
