A cellular telecommunication switching system responsive to an emergency call from a cellular telephone to request that the geo-coordinates be transmitted from the cellular telephone and to convert those coordinates into conventional municipality or rural address location information. In one embodiment, the cellular telecommunication switching system utilizes an internal database to convert the geo-coordinates to location information. In another embodiment, the cellular telecommunication switching system utilizes an external database to perform this conversion. In yet a third embodiment, a cellular telephone performs the conversion and transmits to the cellular telecommunication switching system the location information.
A cellular switching system for providing public emergency call service to a cellular telephone set, comprising: means for detecting a public emergency call from a cellular telephone set; means for requesting the transmission of geo-coordinates from the cellular telephone set; means for converting t
A cellular switching system for providing public emergency call service to a cellular telephone set, comprising: means for detecting a public emergency call from a cellular telephone set; means for requesting the transmission of geo-coordinates from the cellular telephone set; means for converting the geo-coordinates received as digital information from the cellular telephone set to location information; means for establishing a digital link to the public safety answering point system; means for transmitting the location information to a public safety answering point system and for establishing a voice communication path between the cellular telephone set and the public safety answering point system; the convening means further adapted for translating the location information into audio information upon the means for establishing the digital link being unable to establish a digital link to the public safety answering point system; and the transmitting means further adapted for communicating the audio information to the public safety answering point system.
