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.

said plurality of message handling units cooperating to effect querying said at least one communication network to ascertain a geographic location of said calling instrument substantially contemporaneously with said extant call; and

said plurality of message handling units cooperating to use said geographic location for routing said extant call to at least one selected special number answering station coupled with said at least one communication network and situated generally proximate with said geographic location;

said at least one selected special number answering station cooperating with said plurality of message handling units to establish two-way chat session communications between said calling instrument and said at least one selected special number answering station in said text messaging call format using said first communication channel and said second communication channel.

2. A system for handling special number calls placed from a calling instrument using a text messaging format as recited in claim 1 wherein said geographic location is provided to said at least one selected special number answering station substantially contemporaneously with said extant call.

3. A system for handling special number calls placed from a calling instrument using a text messaging format as recited in claim 1 wherein said at least one selected special number answering station is configured for cooperating with said plurality of message handling units after receiving said extant call for initiating a query to said calling instrument for updating said geographic location.

4. A system for handling special number calls placed from a calling instrument using a text messaging format as recited in claim 1 wherein said at least one communication network includes at least one converting unit coupled with at least one call route established between said calling instrument and said at least one selected special number answering station using selected message handling units of said plurality of message handling units;

said at least one converting unit effecting conversion of calls from said text messaging format to at least one of an audio format and a visual format.

5. A system for handling special number calls placed from a calling instrument using a text messaging format as recited in claim 4 wherein said geographic location is provided to said at least one selected special number answering station substantially contemporaneously with said extant call.

6. A system for handling special number calls placed from a calling instrument using a text messaging format as recited in claim 4 wherein said at least one selected special number answering station is configured for cooperating with said plurality of message handling units after receiving said extant call for initiating a query to said calling instrument for updating said geographic location.

7. A system for handling special number calls placed from a calling instrument using a text messaging format as recited in claim 5 wherein said at least one selected special number answering station is configured for cooperating with said plurality of message handling units after receiving said extant call for initiating a query to said calling instrument for updating said geographic location.

8. A system for handling emergency service calls placed from a calling instrument using a text messaging format;

the system comprising;

a plurality of message handling units configured in at least one communication network accessible by said calling instrument;

at least one selected message handling unit of said plurality of message handling units operating to recognize and receive an extant call placed from said calling instrument in said text messaging call format using an emergency service number via a first communication channel;

said at least one selected message handling unit establishing a second communication channel with said calling unit for supporting text messaging communications;

said plurality of message handling units cooperating to effect querying said at least one communication network to ascertain a geographic location of said calling instrument substantially contemporaneously with said extant call; and

said plurality of message handling units cooperating to use said geographic location for routing said extant call to at least one selected public service answering position coupled with said at least one communication network and situated generally proximate with said geographic location;

said at least one selected special number answering station cooperating with said plurality of message handling units to establish two-way chat session communications between said calling instrument and said at least one selected public service answering position in said text messaging call format using said first communication channel and said second communication channel.

9. A system for handling emergency service calls placed from a calling instrument using a text messaging format as recited in claim 8 wherein said geographic location is provided to said at least one selected public safety answering position substantially contemporaneously with said extant call.

10. A system for handling emergency service calls placed from a calling instrument using a text messaging call format as recited in claim 8 wherein said at least one selected public safety answering position is configured for cooperating with said plurality of message handling units after receiving said extant call for initiating a query to said calling instrument for updating said geographic location.

11. A system for handling emergency service calls placed from a calling instrument using a text messaging call format as recited in claim 8 wherein said at least one communication network includes at least one converting unit coupled with at least one call route established between said calling instrument and said at least one selected public safety answering position using selected message handling units of said plurality of message handling units;

said at least one converting unit effecting conversion of calls from said text messaging format to at least one of an audio format and a visual format.

12. A system for handling emergency service calls placed from a calling instrument using a text messaging call format as recited in claim 11 wherein said geographic location is provided to said at least one selected public safety answering position substantially contemporaneously with said extant call.

13. A system for handling emergency service calls placed from a calling instrument using a text messaging call format as recited in claim 11 wherein said at least one selected public safety answering position is configured for cooperating with said plurality of message handling units after receiving said extant call for initiating a query to said calling instrument for updating said geographic location.

14. A system for handling emergency service calls placed from a calling instrument using a text messaging call format as recited in claim 12 wherein said at least one selected public safety answering position is configured for cooperating with said plurality of message handling units after receiving said extant call for initiating a query to said calling instrument for updating said geographic location.

15. A method for handling special number calls placed from a calling instrument using a text messaging format;
