Abstract
A multi-standard indoor mobile radio access network having a centralized device is provided. In one embodiment of the present invention, a centralized device is configured to transmit a wake-up signal to a wireless device once the wireless device has entered a service area, wherein the wake-up signal triggers the downloading and/or opening of an application on the wireless device configured to determine whether a 911 call has been made. If a 911 call has been made, the application transmits a notification signal to the centralized device. In response thereto, the centralized device transmit location information of the wireless device to an emergency responder. The centralized device also transmits a “ping” to the wireless device during predetermined periods of time in order to keep the application open and/or installed on the wireless device.
