Abstract

A directory assistance method and system to provide directory assistance information to users at computer terminals without operator assistance. The directory assistance information is requested in a computer protocol and converted to a telephone protocol, then the retrieved from a telephone data base.

Claims

1. A method of providing directory assistance information comprising the steps of:

(a) receiving a request message from a computer system, the request message being in a first computer protocol and specifying the desired directory assistance information;

(b) converting the request message to a telephone protocol;

(c) transmitting the request message in the telephone protocol to a telephone data base server through a telephone communication network;

(d) searching the telephone data base server for the directory assistance information;

(e) creating a response message;

(f) transmitting the response message to the protocol converter in the telephone protocol;

(g) converting the response message to the first computer protocol; and

(h) transmitting the response message to the computer system in the first computer protocol.

2. The method of providing directory assistance information as recited in claim 1, wherein the step of receiving a request message from a computer system includes:

(a) entering a directory assistance request message at a computer terminal;

(b) transmitting the request message through a computer network in the computer system using a second computer protocol;

(c) converting the directory assistance request message to the first computer protocol; and

(d) transmitting the directory assistance request message in the first computer protocol to a protocol converter.

3. The method of providing directory assistance information as recited in claim 2, wherein the step of transmitting the response message includes:

(a) transmitting the response message from the protocol converter to a network server in the computer system in the first computer protocol;

(b) converting the response message to the second computer protocol;

(c) transmitting the response message through a computer network to a computer terminal in the second computer protocol; and

(d) displaying the response message at the computer terminal.

4. A directory assistance system comprising:

a protocol converter connected to a computer system, the protocol converter converting a request message received from the computer system from a first computer protocol to a telephone communication protocol, the request message specifying a desired directory assistance information;

a telephone communication network connected to the protocol converter; and

a telephone data base server connected to the telephone communication network, the telephone data base server retrieving the desired directory assistance information in response to the request message in the telephone communication protocol to produce a telephone response message.

5. The directory assistance system as recited in claim 4 wherein the computer system comprises:

(a) a network server for converting messages between the first computer protocol and a second computer protocol, the network server being connected to the protocol converter;

(b) a computer network utilizing the second computer protocol, the computer network being connected to the network server; and

(c) a computer terminal for entering the directory assistance request message and retrieving the directory assistance response message, the computer terminal being connected to the computer network.

6. The directory assistance system as recited in claim 5 wherein the computer network is connected to the Internet.

7. The directory assistance system as recited in claim 4 wherein the first computer protocol is a Transmission Control Protocol/Internet Protocol and the telephone communication protocol is a Signaling System 7 protocol.

8. The directory assistance system as recited in claim 4, further comprising the computer system.
