Abstract

An application module associated with a telecommunication exchange serving a particular subscriber stores a directory number representing a called party subscriber and time data representing the time a call connection between the subscriber and the called party subscriber should be established. Thereafter, whenever the specified time represented by the time data occurs, the application module establishes a first call connection with the subscriber, informs the subscriber of the requested call connection, and in response to an affirmative confirmation, establishes a second call connection between the subscriber and the previously indicated called party subscriber. Such call connections can be effectuated in accordance with the subscriber'"'"'s call setup option, e.g., daily, weekly, monthly, yearly, etc.

Claims

1. A method for establishing a call connection between a calling subscriber and a called party subscriber within a telecommunications system, said method comprising the steps of:

a) receiving a predefined activation service code from said calling subscriber, said code corresponding to a service for making an automatic call connection request;

b) in response to receiving said code, authenticating said calling subscriber by determining a first directory number of said calling subscriber, and upon positive authentication;

c) storing a second directory number of said called party subscriber indicated by said calling subscriber at a telecommunications exchange which services said calling subscriber;

d) storing a time value associated with said second directory number, said time value corresponding to any predetermined point in time indicated by said calling subscriber for establishing said call connection;

e) determining that said predetermined point in time corresponding to said time value has been reached;

f) originating a first call back from said telecommunications exchange to said calling subscriber;

g) confirming that said calling subscriber has answered said first call back;

h) originating a second call back to said called party subscriber at said retrieved second directory number; and

i) connecting said first call back to said second call back to establish said call connection between said calling subscriber and said called party subscriber.

2. The method of claim 1 wherein said time value represents a particular time of day and day of week.

3. The method of claim 1 wherein said time value represents a particular time of day and day of year.

4. The method of claim 1 wherein said confirming step g) further comprises the steps of:

g1) confirming that said calling subscriber wishes to establish said call connection; and

g2) establishing said call connection.

5. The method of claim 4 wherein said confirming step g) further comprises the steps of:

playing an announcement message to said calling subscriber informing said subscriber that said point in time for establishing said call connection has been reached; and

performing steps g1) and g2) of claim 4.

6. The method of claim 5, further comprising the steps of:

in response to a negative confirmation, determining whether said calling subscriber wishes to cancel the establishment of said call connection; and

in response to an affirmative determination, canceling the establishment of said call connection;

otherwise,

determining whether a number of attempts specified by said telecommunications exchange has been exceeded;

in response to a negative determination,

waiting a particular period predefined by said telecommunications exchange; and

determining that said calling subscriber is either busy or non-responsive to said first call back;

determining that a number of attempts specified by said telecommunications exchange has not yet been exceeded;

waiting a particular period predefined within said telecommunications exchange; and

reattempting the origination of said first call back after the expiration of said period.

8. A method for establishing a call connection within a telecommunications system between a calling subscriber and a called party subscriber, said method comprising the steps of:

a) receiving a predefined activation service code from said calling subscriber, said code corresponding to a service for making an automatic call connection request;

b) in response to receiving said code, authenticating said calling subscriber by determining a first directory number of said calling subscriber, and upon positive authentication;

c) receiving an indication from said calling subscriber to establish a call connection towards said called party subscriber at any predetermined point in time indicated by said calling subscriber;

d) determining that said predetermined point in time has been reached; and

e) establishing a call connection automatically between said calling subscriber and said called party subscriber.

9. The method of claim 8 wherein said step of establishing said call connection further comprises the steps of;

establishing a first call connection from said telecommunications system to said calling subscriber;

recognizing that said calling subsscriber has answered said call conection;

establishing a second call connection from said telecommunications sytem to said called party subscriber; and

connecting said first call connection with said second call connection.

10. The method of claim 9 wherein said step of recognizing that said calling subscriber has answered said call connection further comprises the steps of:

informing said calling subscriber of a scheduled call connection request towards said called party subscriber;

requesting a confirmation from said calling subscriber; and

in response to an affirmative confirmation, establishing said second call connection;

otherwise,

disconnecting said first call connection;

waiting a particular period specified by said telecommunications system; and

repeating the steps of claim 9.

11. The method of claim 9, wherein in response to said calling subscriber being busy or not answering said first call connection, further comprising the steps of:

determining whether a number of attempts specified by said telecommunications system has been attempted; and

in response to a negative determination,

waiting a particular period specified by said telecommunications system; and

repeating said steps of claim 9;

otherwise

removing said indication from said telecommunications system.

12. An apparatus for establishing a call connection between a calling subscriber and a called party subscriber within a telecommunications system, comprising:

an authentication module for receiving a predefined activation service code from said calling subscriber, said code corresponding to a service for making an automatic call connection request, and in response to receiving said code, authenticating said calling subscriber by determining a first directory number of said calling subscriber;

a register for storing a second directory number indicated by said calling subscriber, said time value indicated by said calling subscriber, said time value corresponding to any point in time indicated for establishing said call connection;

a switch for establishing said call connection; and

an application module for determining that said point in time corresponding to said time value has been reached and for instructing said switch to establish said call connection between said calling subscriber and said called party subscriber.

13. The apparatus of claim 12 wherein said time value represents a particular time of day and day of week.

14. The apparatus of claim 12 wherein said time value represents a particular time of day and day of year.

15. The apparatus of claim 12 wherein said application module in establishing said call connection further instructs said switch to:
