Abstract
A wireless communications device can be triggered by a user in a duress situation to provide to a predetermined recipient, or to a monitoring service, a duress message containing emergency-response information, such as GPS coordinates, a photograph and/or an audio clip to facilitate an emergency response to the duress situation. The wireless device can periodically send follow-up duress messages to provide updated GPS data, photos or other information. The wireless device monitoring can also reply to specific queries from the monitoring service to provide requested information that would be most useful to the recipient attempting to coordinate an emergency response. In the event that the device is outside data packet coverage, the duress message can be transmitted using an alternate mode of communication such as SMS or MMS. If no mode of communication is available, the device stores the duress message until communications are possible.
