Abstract

The present invention provides a method and apparatus for prepayment of telecommunication connections between first and second telecommunication devices operably associatable with the telecommunication lines of a telecommunication switching network. In general, the method involves storing telecommunication-time data representative of a prepurchased amount of telecommunication-time available for payment of telecommunication connections in the telecommunication switching network. At the initiation of the first telecommunication device, a telecommunication connection is established between the first and second telecommunication devices so that a telecommunication process can be conducted therebetween. The telecommunication connection between the first and second telecommunication devices is terminated in response to termination of the telecommunication process. The time duration of the telecommunication connection is measured. The stored telecommunication-time data is processed to indicate a decrement in the available telecommunication-time, which is essentially equal to the measured time duration of the telecommunication connection. Various embodiments of telecommunication-time metering apparatus are provided for carrying out the method of the present invention.

Claims

1. Telecommunication-time metering device utilizable by a first information transferring device for prepayment of information transfers between said first information transferring device and a second information transferring device operably associated with the telecommunication lines of a telecommunication network, said telecommunication-time metering device comprising:

data storage means for storing telecommunication-time data representative of a prepurchased amount of telecommunication-time available to said first information transferring device, for prepayment of information transfers between said first and second information transferring devices within said telecommunication network;

time metering means for measuring the time duration of each information transfer between said first and second information transferring devices within said telecommunication network; and

data processing means for processing said stored telecommunication-time data within said data storage means so as to indicate decrements in said prepurchased amount of telecommunication-time, said decrements being substantially equal to the measured time duration of said information transfer.

2. The telecommunication-time measuring device of claim 1, which further comprises a display means in operable association with said data storage means, for visually displaying a graphical representation of the balance of said prepurchased amount of telecommunication-time.

3. The telecommunication-time measuring device of claim 1, wherein the balance of said prepurchased amount of telecommunication-time is continously visually displayed during each said information transfer.

4. The telecommunication-time measuring device of claim 1, which further comprises an alarm generating means for generating a perceptible alarm signal in response to said telecommunication-time data representing a balance of prepurchased telecommunication-time that is less than a predetermined time-threshold value.

5. The telecommunication-time measuring device of claim 1, wherein said data storage means comprises a data reading/writing means for reading telecommunication-time data stored in a portable data storage device, and for writing processed telecommunication-time data representative of said prepurchased amount of telecommunication time.

6. The telecommunication-time measuring device of claim 5, wherein said data reading/writing means comprises means for reading telecommunication-time data stored on a magnetic card storage device, and for writing processed telecommunication-time data thereon.

7. The telecommunication-time measuring device of claim 1, wherein said first information transferring device comprises a first digital information transferring system, and said second information transferring system comprises a second digital information transferring system.
