Abstract

A method and apparatus for providing electronically mailable call credits and call connections to be charged thereto are purchased by a customer for a recipient through the Internet and sent via email to the recipient. The recipient requests a call by activating an icon associated with the email. An application server receives the request and sends a call request message via the Internet to a virtual switching point associated with a switched telephone network. The virtual switching point initiates actions in the switched telephone network to set up a telephone communication between the recipient and a party to be called.

4. A method as claimed in claim 3 wherein the at least one party is the customer.

5. A method as claimed in claim 3 wherein the at least one party is a person other than the customer.

6. A method as claimed in claim 1 wherein the electronic certificate is associated with a message from the customer to the recipient.

7. A method as claimed in claim 6 wherein the message is a text message.

8. A method as claimed in claim 6 wherein the message is an audible message.

9. A method as claimed in claim 6 wherein the electronic certificate is associated with an electronic greeting card.

10. A method as claimed in claim 2 further comprising the steps of:

receiving at an application server a call request as a result of an action by the recipient who activates the icon, the call request including the unique identifier, a calling telephone number, an Internet Protocol (IP) address of the recipient and a telephone number of a party to be called by the recipient;

verifying the electronic certificate using the unique identifier to locate the information stored in the database; and

sending a call request message to a call control node in a switched telephone network to instruct the call control node to initiate actions in the switched telephone network to establish a telephone connection between the calling telephone number and the called telephone number.

11. A method as claimed in claim 10 wherein massages exchanged via the data network between the recipient and the application server when the icon is activated are encrypted.

12. A method as claimed in claim 10 wherein the call request message sent to the call control node includes the calling and called telephone numbers and a maximum call duration determined using a remaining value of the call credits and the unique identifier.

13. A method as claimed in claim 10 further comprising the steps of:

prior to sending the call request to the call control node, calculating at the application server a maximum call duration for the call requested in accordance with a remaining value of the call credits stored in the database information associated with the unique identifier;

sending from the application server to the recipient a message respecting the maximum call duration using the IP address;

receiving at the application server from the recipient a confirmation of the call request.

14. A method as claimed in claim 12 further comprising the step of:

reporting from the call control node to the application server an actual call duration after the telephone communication is completed or is terminated by the CCN after the maximum call duration has expired.

15. A method as claimed in claim 14 further comprising the steps of:

receiving at the application server from the call control node via the data network a call duration report associated with the unique identifier;

retrieving at the application server from the database the information associated with the unique identifier;

calculating a charge for the telephone call using the call duration;

deducting the charge from the remaining value of the call credits to yield an updated remaining value; and

storing the updated remaining value of the call credits in the database with the information associated with the unique identifier.

16. A method as claimed in claim 14 wherein the telephone connection is established using common channel signaling messages generated by a call control node that is a physical node in a common channel signaling network and a virtual node in facilities used to establish the connection.

17. A method as claimed in claim 16 wherein establishing the telephone connection further comprises the steps of:

generating a first initial address message (IAM) at the call control node and transmitting the first IAM through the common channel signaling network to establish a first connection with the calling party;

receiving at the call control node an indication that the connection with the calling party was established;

generating a second IAM at the call control node and transmitting the second IAM through the common channel signaling network to establish a second connection with the called party;

whereby the first and second IAMs are interrelated to an extent that a circuit identification code in each of the first and second IAMs relate to opposite ends of the same facility.

18. A method of establishing telephone connections in a switched telephone network for a holder of a pre-paid electronic call certificate, comprising the steps of:

receiving at an application server in a data network a call message generated as a result of an action by the holder of the electronic call certificate, the holder having activated an icon associated with the electronic call certificate;

verifying the electronic call certificate using the information in the call request message to query a database of information identifying valid electronic call certificates;

sending a call setup message via the data network to a call control node in the switched telephone network to instruct the call control node to initiate actions in the switched telephone network to establish a telephone connection between a calling party number and a called party number specified in the call request;

tracking a duration of the call at the call control node;

computing a charge for the call connection using the duration of the call; and

deducting the charge from a remaining value of the call credits and storing a remaining value in the database as updated electronic call certificate information.

19. An apparatus for providing electronically mailable call credits, comprising:

an application server adapted to be connected to a data network;

a memory associated with the application server for storing information in a database;
