Abstract

An improved decoding and processing system is provided for advanced determination and display of geographic information to a called party relating to the call origination party. The improved system comprises a receiving device to receive an MDMF or SDMF format message from a local CO switch containing call identification data; a microcontroller storage and retrieval device containing a data base library for selectively determining the corresponding geographic information such as city and/or state by matching the area code and/or local exchange number received from the call origination party; and a readout device for displaying the city and/or state of the incoming call. Preferably, the system includes capability to automatically update the data base library of the storage and retrieval device as new area codes and/or local exchanges are subsequently assigned. Accordingly, the improved system provides the user with convenient and efficient display of geographic information related to caller identification that is capable of determining an ever increasing number of area code and local telephone exchange numbers.

Claims

1. An improved decoding and processing system for advanced determination and display of geographic caller information, said system comprising:

a receiving device to receive an MDMF or SDMF format message from a local CO switch containing call identification data from a call origination party;

a microcontroller storage and retrieval device containing a data base library for selectively determining the corresponding geographic information of the call origination party by matching the area code and/or local exchange number received from the call origination party with geographic information derived from the data base library;

said device comprising off- hook reception means for automatically updating the data base library with current information as new area codes and/or local exchanges are subsequently assigned; and

a readout device for displaying the geographic information including a call data character stream related to the call origination party.

2. The improved system of claim 1 wherein the standard data field is a data field for a dialed number.

3. The improved system of claim 1 wherein the call data character stream replaces the contents of the standard data field.

4. The improved system of claim 1 wherein the call data character stream references information stored in a database.

5. The improved system of claim 1 wherein the call data character stream is used to process the voice path of the telephone call.

6. The improved system of claim 1 wherein the call geographic information is a city identification of the call origination party.

7. The improved system of claim 1 wherein the call geographic information is a state identification of the call origination party.

8. The improved decoding and processing system of claim 1 wherein said microcontroller storage and retrieval device comprises a built in DTMF dialer to communicate with a central server having current information for updating the data base with current corresponding geographic data.

9. The improved decoding and processing system of claim 8 wherein said central server initiates the transfer of current information for updating the data base using a CAS signal, which is acknowledged by said microcontroller device with a DTMF tone.

10. The improved decoding and processing system of claim 9 wherein said central server transmits updated current information to said microcontroller device that is received and interpreted using a FSK decoder.
