Abstract

The present invention provides a method and apparatus for prepayment of telecommunication connections between first and second telecommunication devices operably associable with the telecommunication lines of a telecommunication switching network. In general, the method involves storing monetary value data representative of a prepaid e.g. deposited in a centralized storage device, amount of monetary value 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 cost of the telecommunication connection is computed using the measured time duration and applicable prepaid rate data. The stored monetary value data is processed to indicate a decrement in the available prepaid monetary value, which decrement is essentially equal to the computed cost of the telecommunication connection. Telecommunication cost computing apparatus are provided for carrying out the method of the present invention using various telecommunication devices including privately sponsored prepay-type and cellular phones. Advantageously, the present invention allows groups of registered subscribers to prepay a bulk amount of monetary funds for telecommunication connections initiated by the members of the registered group, and thereby acquire preferred calling rates.

Claims

1. A method for prepayment of telecommunication connections between two or more telecommunication devices each operably associable with telecommunication lines of a telecommunication switching network having a central switching system operably connected to a billing system, said method comprising the steps:

(a) storing in a first storage means in said central switching system, a group of subscriber numbers, each said subscriber number being associated with a subscriber line having membership to a prepaid group of subscriber lines;

(b) storing in a second storage means in said billing system, monetary value data representative of a prepaid amount of monetary value available to each said subscriber line of said prepaid group, for payment of the cost of telecommunication connections in said telecommunication switching network;

(c) transmitting a first called party number over a first subscriber line to said central switching system, in order to establish a first telecommunication connection between at least a first pair of telecommunication devices, wherein at least one of said first pair of telecommunication devices is operably associated with said first subscriber line;

(d) at said central switching system, determining that said first subscriber line is in said prepaid group of subscriber lines;

(e) at said central switching system, measuring the time duration of said first telecommunication connection;

(f) at said billing system, computing the cost of said first telecommunication connection using applicable rate data and said measured time duration of said first telecommunication connection; and

(g) at said billing system, processing said stored monetary value data of said prepaid group, to indicate a first decrement in said prepaid amount of monetary value, said first decrement being essentially equal to said computed cost of said first telecommunication connection.

2. The method of claim 1, which further comprises:

(h) transmitting a second called party number over a second subscriber line to said central switching system, in order to establish a second telecommunication connection between at least a second pair of telecommunication devices, wherein at least one of said second pair of telecommunication devices is operably associated with said second subscriber line;

(i) determining that said second subscriber line is in said prepaid group of subscriber lines;

(j) at said central switching system, measuring the time duration of said second telecommunication connection;

(k) at said central switching system, computing the cost of said second telecommunication connection using applicable rate data and said measured time duration of said second telecommunication; and

(l) at said central switching system, processing said stored monetary value data of said prepaid group to indicate a second decrement in said prepaid amount of monetary value, said a second decrement being essentially equal to said computed cost of said second telecommunication connection.

3. Apparatus for prepayment of telecommunication connections between two or more telecommunication devices each operably associable with telecommunication lines of a telecommunication switching network having a central switching station operably connected to a billing system, said apparatus comprising:

group register means, in said central switching system, for registering a group of numbers, each said number corresponding to a subscriber line having membership to a prepaid group of subscriber lines;

data storage means, in said billing system, for storing monetary value data representative of a prepaid amount of bulk monetary value available to each subscriber line in said prepaid group, for payment of the cost of telecommunication connections in said telecommunication switching network;

measuring means, in said central switching system, for measuring the time duration of a telecommunication connection established between two or more telecommunication devices, one of which is operably associated with one said subscriber line of said prepaid group;

computing means, in said billing system, for computing the cost of said telecommunication connection using applicable rate data and said measured time duration; and

processing means, in said billing system, for processing said bulk amount of monetary value data so as to indicate at least one decrement in said bulk amount of prepaid monetary value, said at least one decrement being essentially equal to said computed cost of said telecommunication connection.

4. The apparatus of claim 3, wherein said group register means, in said central switching system, stores a plurality of numbers corresponding to a plurality of prepaid subscriber lines belonging to an entity selected from the group consisting of a cooperative apartment, a condominium complex and a business organization.

5. The apparatus of claim 3, which further comprises data monitoring means, in said billing system, for storage means.
