First Claim
1. A method for transmitting an emergency call including emergency information from a vehicle using a mobile communication system, comprising:
- triggering an emergency call at the vehicle,establishing a data connection to an emergency call assistance center via the mobile communication system in which the data connection comprises a Wireless Application Protocol (WAP) connection,transmitting a first portion of the emergency information to the emergency call assistance center using the WAP data connection as a request for a uniform resource locator (URL) that includes the first portion of the emergency information within the URL request,establishing a first voice connection to the emergency call assistance center via the mobile communication system, andtransmitting a dual tone multi-frequency (DTMF) message including a second portion of the emergency information using the established first voice connectionwherein the first portion of the emergency information and the second portion of emergency information include redundant emergency information; and
synchronizing the first portion of the emergency information and the second portion of the emergency information at the emergency assistance center such that errors during transmission may be corrected.
