Abstract

During a telephone or other connection an exchange stores information about charges to be made for that connection. To provide flexible charging the exchange responds to a charge variation request signal to transmit to a party by whom a proposed charge is to be borne a signal requiring acknowledgement and to modify a respective portion of the store contents relating to said connection in progress only if such an acknowledgement is received, so as to vary the charging arrangements, for example to invoke a higher rate of charge, or alternatively to change the party by whom charges are to be borne.

Claims

1. A telecommunications exchange including

a store (13) for storing records (CDRs) containing information as to the cost of connections

control means (11) responsive to a connection being established between a calling party and a called party to create in the store a respective record containing charge information for the connection, and responsive, during the connection of said parties, to receipt of a charge variation request signal from one of said parties, to

(a) transmit to whichever of said parties is to bear a proposed charge a signal requiring acknowledgement

(b) modify the respective record upon receipt of such an acknowledgement.

3. A telecommunications exchange or network according to claim 1 or claim 2, in which the control means is operable to send, upon receipt of the acknowledgement, a confirmation signal to whichever of said parties the charge variation request signal was received from.

9. A telecommunications exchange according to claim 1 or claim 2, in which the control means is responsive to an assigned request signal for a charge reversal

(a) so to modify the respective record that charges to the party currently being charged shall be cancelled, or shall cease

(b) to transmit to another exchange participating in the connection a request that that other exchange create said further respective record.

10. A telecommunications network according to claim 1 or claim 2, in which said store is disposed in a first exchange (1a), a corresponding store is disposed in another exchange (1b), which other exchange participates in the connection, and the control means is responsive to an assigned request signal for a charge reversal

(a) so to modify the respective record that charges to the party currently being charged shall be cancelled, or shall cease

(b) to transmit to said other exchange participating in the connection a request that that other exchange create in said corresponding store said further respective record.

11. A telecommunications exchange or network according to claim 1 or claim 2, in which the control means is operable in response to an assigned request signal for charge rate modification so to modify the respective record that the charging rate for continuation of the call shall be different from that obtaining prior to the receipt of that request signal.

12. A telecommunications exchange or network according to claim 11, in which the control means is operable in response to an assigned request signal for temporary charge rate modification so to modify the respective record that the charging rate for continuation of the call shall for a specified period or for the remainder of the call if shorter be different from that obtaining prior to the receipt of that request signal.

2. A telecommunications network including

a store (13) for storing records (CDRs) containing information as to the cost of connections

control means (11) responsive to a connection being established between a calling party and a called party to create in the store a respective record containing charge information for the connection, and responsive, during the connection of said parties, to receipt of a charge variation request signal from one of said parties, to

(a) transmit to whichever of said parties is to bear a proposed charge a signal requiring acknowledgement

(b) modify the respective record upon receipt of such an acknowledgement.

4. A telecommunications exchange or network according to claim 2, including voice announcement means (16) and in which the signal requiring acknowledgement and/or the confirmation signal is a voice signal representing a spoken message.

5. A telecommunications exchange or network according to claim 2, in which the control means is responsive to an assigned charge variation request signal for a charge reversal to modify the respective record such as to replace the identity of whichever of said parties is currently being charged by the identity of the other of said parties.

6. A telecommunications exchange or network according to claim 2, in which the control means is responsive to an assigned charge variation request signal for a charge reversal

(a) so to modify the respective record as to cancel the charge to whichever of said parties is currently being charged;

and

(b) to create a further respective record for the connection, which further respective record contains information to enable the charge for the connection to be borne by the other of said parties.

7. A telecommunications exchange or network according to claim 2, in which the control means is responsive to an assigned charge variation request signal for a charge reversal

(a) so to modify the respective record as to delete said respective record from the first store;

and

(b) to create a further respective record for the connection, which further respective record contains information to enable the charge for the connection to be borne by the other of said parties.

8. A telecommunications exchange or network according to claim 2, in which the control means is responsive to an assigned charge variation request signal for a charge reversal

(a) so to modify the respective record as to cease the charge to whichever of said parties is currently being charged;

and

(b) to create a further respective record for the connection, which further respective record contains information to enable the charge for the subsequent part of the connection to be borne by the other of said parties.

13. A telecommunications exchange or network according to claim or claim 2, in which the control means is operable in response to an assigned request signal for a single charge so to modify the respective record that an additional charge shall be made.

14. A method of operating a telecommunication network including the steps of;

(a) making a connection between a first and a second party;

(b) creating a respective record (CDR) containing information as to the charge to be made for the connection;

(c) receiving, during said connection, a charge variation request signal from one of said parties; and

in response

(d) transmitting, to whichever of said parties is to be bear a proposed charge, a signal requiring acknowledgement; and

(e) modifying said respective record upon receipt of such an acknowledgement.
