Abstract

An improved emergency response system is provided. The system includes a patient or subscriber location database having a schedule of patient or subscriber activities. In one implementation, an emergency services server detects when the patient or subscriber is having a possible medical event as indicated by medical physiologic data transmitted from a wireless communication device proximate the patient. A third party such as a technologist and/or doctor diagnoses the patient and determines whether treatment is required. If treatment is required, a phone located remotely from the patient is used to call an emergency services first responder from a public safety access point in the patient'"'"'s location. The remotely located phone has an automatic location identification database record that is updated based on the patient'"'"'s current location as indicate by the patient location database. The address information in the patient location database includes street number, building number, floor and room number information, if applicable, to ensure that first responders are directed to the patient'"'"'s specific location. Other implementations of the emergency response system are also described, including natural disasters, home security, and travel applications.
