Text message generation for emergency services as a backup to voice communications

摘要

A mobile device may detect when a calling party dials an emergency service to request emergency assistance. Following input of the dialed digits, the device may automatically generate a text message in addition to initiating a voice call, both of which may be transmitted over a wireless data network. The wireless network may correlate the two calls as originating from the same emergency situation and may attempt to deliver the two calls to a Public Services Answering Position (PSAP) at an appropriate emergency center. If the PSAP does not receive a voice call, the PSAP may communicate with the device via test messaging.
