Abstract: A computer-implemented method of processing an emergency call reported to a Public Safety Answering Point (PSAP) by a user of a first communication device can include an Emergency Service Routing Proxy (ESRP) performing a search operation to track location data of the first communication device in response to receiving an emergency callback request from the PSAP that has received an emergency call from a first communication device. The callback request can be forwarded to a most appropriate gateway of a carrier according to the first communication device's location data. An SIP INVITE request comprising a new header including a request for forking SMS for initiating, at the carrier a procedure for retrieving mobile network addresses of communication devices that are co-located to the first communication device can be sent in response to the callback request not being answered by the first communication device.

Abstract: A method of processing an emergency incident reported to a Public Safety Answering Point (PSAP) by a user of a mobile communication device can include receiving an emergency call, determining the geolocation of the mobile communication device that made the emergency call; triggering an SMS-CB so SMS messages are sent to mobile communication devices located within a predetermined area around the determined geolocation of the device that made the emergency call, and receiving a plurality CB-SMS response messages that include objects related to the emergency incident. An object comparison on objects extracted from the responses can be performed to determine a similarity of the objects with respect to each other. It can also be verified whether the similar objects have been received from co-located mobile communication devices.
