ESTABLISHING EMERGENCY CALLS WITHIN A MOBILE TELECOMMUNICATIONS NETWORK

摘要

A location of a first emergency call connection requested from a mobile station within a mobile telecommunications network is determined. Thereafter, if a second emergency call connection is requested from another mobile station within approximately the same geographic area or location, an announcement message informing the caller of the already reported incident is provided. The caller then has the option of terminating the call or connecting to a Public Safety Answering Point (PSAP) operator. An application module associated with the serving mobile telecommunications network may further transmit unstructured data, such as Short Message Service (SMS) or Unstructured Supplementary Service Data (USSD) messages, to all other mobile stations currently traveling within the reported location or area. Such reporting enables other mobile subscribers to be informed of the reported incident and not to request emergency call connections in an attempt to report the same incident. It may further enable other mobile stations to avoid or detour around the reported site.
