Abstract

Existing wire-line public switched telephone networks and Caller Identification (“CallerID”) systems operated by local telephone companies are utilized to deliver email notification to users via the users'"'"'telephone lines. The present invention queries the user'"'"'s ISP remote server to determine whether any email addressed to the user is received by and/or stored thereon and, if so, causes an associated CallerID server of, for instance, the local telephone company to send an email notification signal in a format compatible with operating CallerID protocols to an email notification device using a public switched telephone network. By transmitting email notification signals over existing telephone lines, the present invention is widely available to users and advantageously eliminates the need for users to maintain a paging or cable service and, perhaps more importantly, does not require the user to maintain an online cable connection, an online Internet connection, or a paging device. In some embodiments, email notification signals in accordance with the present invention are transmitted during telephone ringing intervals and, in other embodiments, are transmitted prior to the first telephone ringing signal. In one embodiment, an email notification signal containing at least a portion of the text of unread email received by and/or stored on the user ISP email server is transmitted to the user via the public switched telephone network.

Claims

1. An email notification system for transmitting to a user an email notification signal indicating that email addressed to the user is received at an email server remote from the user, the system comprising:

a public switched telephone network having at least one local loop associated with the user;

at least one central office coupled to the public switched telephone network and coupled to the email server;

a CallerID server for routing the email notification signal to the user;

an email notification device coupled to the central office via at least one of the at least one local loop of the public switched telephone network, the email notification device receiving the email notification signal transmitted from the central office and, in response thereto, alerting the user as to the email addressed to the user; and

the email notification signal representing alphanumeric data related to at least a portion of a text message of one or more email received on the remote email server.

2. The system of claim 1, wherein the central office is coupled to the remote email server via the Internet.

3. The system of claim 1, wherein the central office includes and operates the remote email server.

4. The system of claim 1, wherein the email notification device comprises an alert indicating means.

5. The system of claim 4, wherein the alert indicating means comprises a light-emitting device.

6. The system of claim 4, wherein the alert indicating means comprises a speaker.

7. The system of claim 4, wherein the email notification device further comprises a display means for displaying the number of email messages received on the remote email server.

8. The system of claim 4, wherein the email notification device further comprises a display means for displaying at least a portion of a text message of one or more email received on the remote email server.

9. The system of claim 1, wherein the email notification device comprises a microprocessor and associated memory.

10. The system of claim 1, wherein the email notification device includes an output terminal coupled to a telephone.

11. The system of claim 10, wherein the email notification device comprises a filter and signal splitting circuit to allow telephone voice calls to pass unmodified to the telephone.

12. The system of claim 1, further comprising a user notification parameter database for storing parameter information pertaining to the user and to the email server.

13. The system of claim 1, wherein the user notification database comprises one or more line entries corresponding to the user for storing an Internet address of the remote email server and an email username and/or password assigned to the user.

14. The system of claim 1, wherein the email notification signal is a CallerID compatible signal.

15. The system of claim 1, further comprising email query software for querying the remote email server at predetermined times to determine whether email addressed to the user is received by the remote email server.

16. The system of claim 15, wherein the email query software is maintained by the central office.

17. The system of claim 15, wherein the email query software is maintained by an information service provider remote from the user.

18. The system of claim 15, wherein a parameter value indicative of the predetermined time is stored within the user notification parameter database.

19. The system of claim 1, wherein the central office is coupled to the remote email server via the Internet.

20. A method of providing to a user a CallerID-compatible email notification signal indicating that email addressed to the user is received at a remote email server associated with the user, the method comprising the steps of:

transmitting a query signal to the remote email server;

transmitting, in response to the query signal, a preliminary email notification signal from the remote email server to a central office coupled to a public switched telephone network;

formatting the preliminary email notification signal into the CallerID-compatible email notification signal according to one or more parameter values; and

transmitting the CallerID-compatible email notification signal from the central office to the user using the public switched telephone network.

21. An email notification device for receiving a CallerID-compatible email notification signal indicating the existence of unread email messages addressed to a user and stored on an email server associated with the user, comprising:

an input terminal coupled to receive the email notification signal transmitted from a CallerID server over a local loop of an associated public switched telephone network;

a microprocessor for processing the email notification signal;

a memory for storing information associated with the email notification signal;

an alert indicating means for alerting the user of receipt of the email notification signal; and

the email notification signal representing alphanumeric data related to at least a portion of a text message of one or more email received on the remote email server.

22. The system of claim 21, wherein the email notification device further comprises an output terminal coupled to a telephone device.

23. The system of claim 21, wherein the alert indicating means comprises a light-emitting device and a speaker.

24. The system of claim 21, wherein the email notification device further comprises a display means indicating the number of unread email messages stored on the email server.

25. The system of claim 21, wherein the email notification device further comprises a display means for displaying a predetermined number of text lines associated with each of the unread email messages stored on the email server.

26. The system of claim 21, wherein the email server is remote from the user.

27. A method of notifying a user that an email message addressed to the user has been received by the user'"'"'s email mail server, the method comprising the steps of:

providing a CallerID server in operable connection with a local loop of a public switched telephone network;

querying the user'"'"'s email mail server to determine the presence or absence of any unread email messages stored thereon;

transmitting, in response to the querying step and using the CallerID server, a CallerID-compatible email notification signal to a notification device operated by the user;

selectively displaying information associated with the email notification signal on the email notification device; and

the email notification signal representing alphanumeric data related to at least a portion of a text message of one or more email received on the remote email server.

28. The method of claim 27, wherein the email notification signal is transmitted to the user'"'"'s email notification device during a silent interval between successive ringing signals of a CallerID-compatible signal.

29. An email notification system for passively receiving at a user'"'"'s email notification device a CallerID-compatible email notification signal indicating the existence of unread email messages addressed to the user and stored on an email mail server associated with the user and connected to the Internet, the system comprising:

a microprocessor having query software operating thereon for querying the email server to determine the existence of any unread email messages stored on the email serve and for generating a preliminary email notification signal in response thereto;
