1. A communication system including
a termination unit; a mobile device configured to perform the following steps:
receive an indication of an emergency from a user; andin response to receiving the indication of the emergency, transmit a first message to the termination unit, wherein the first message is transmitted wirelessly using a local wireless transmission protocol,wherein the termination unit is part of a DAS (Distributed Antenna System) network,wherein the DAS includes a non-wireless internal communication system,wherein the termination unit is configured to perform the following steps:
receive the first message from the mobile device;in response to receiving the first message, transmit a second message to a local distribution device;wherein the second message includes: an identification of the termination unit, the emergency command, the IMSI (International Mobile Subscriber Identity) of the mobile device, the current date and time, and the identification of a cellular communication carrier associated with the mobile device, and a distribution device configured to perform the following steps:
receive the second message; andin response to receiving the second message, sending a third message to a PSAP (Public Safety Answering Point) via a gateway device,wherein the third message includes the identification of the termination unit, the emergency command, the IMSI (International Mobile Subscriber Identity) of the mobile device, the current date and time, and the identification of a cellular communication carrier associated with the mobile device,wherein the third message includes a physical location of the termination unit, wherein the physical location of the termination unit includes a physical location in a multi-tenant building, and wherein the physical location in the multi-tenant building includes one of: an apartment identification and a room identification,wherein the distribution device is part of the DAS (Distributed Antenna System) and is further configured to perform the following additional step:
receive an additional message from an additional termination unit,wherein the additional message includes an additional physical location of the additional termination unit, wherein the additional physical location of the additional termination unit includes an additional physical location in the multi-tenant building, andwherein the additional physical location in the multi-tenant building includes one of: an additional apartment identification and an additional room identification.
