Abstract

A system for handling special number calls placed from a calling instrument using a text messaging format includes: a plurality of message handling units configured in at least one communication network accessible by the calling instrument. At least one selected message handling unit of the plurality of message handling units operates to recognize an extant call placed from the calling instrument using a special number and expressed in the text messaging call format. The plurality of message handling units cooperates to effect querying the calling instrument to ascertain a substantially pinpoint geographic location of the calling instrument substantially contemporaneously with the extant call. The plurality of message handling units cooperates to use the geographic location for routing the extant call to at least one selected special number answering station coupled with the at least one communication network and situated generally proximate with the geographic location.
