Abstract

A system for a caller to control a distinctive ring for a telephone call includes a service switching point and a service control point. The service switching point is operable to receive a feature code and a called directory number, and to issue a query in response to receiving the feature code. The service control point is operable to receive the query and issue a response to the service switching point. The response includes a distinctive ring parameter. Upon receiving the response from the service control point, the service switching point processes the call so that the distinctive ring parameter causes a distinctive ring signal to be applied to a called telephone line associated with the called directory number.

Claims

1. A telephone network, comprising:

a first service switching point being operable to receive a feature code and a called directory number input by a calling party placing a call, and to issue a query in response to receiving the feature code; and

a service control point in communication with the first service switching point over a first communication path, the service control point being operable to receive the query and issue a response to the first service switching point, the response including a distinctive ring parameter;

wherein upon receiving the response from the service control point the first service switching point processes the call so that the distinctive ring parameter causes a distinctive ring signal to be applied to a called telephone line associated with the called directory number;

wherein the first service switching point further operable to receive an authorization code, and include the authorization code in the query; and

the service control point is further operable to determine whether the authorization code is valid or invalid, and provides the distinctive ring parameter only upon determining that the authorization code is valid;

wherein the authorization code is a unique code associated with the calling party, and is generated automatically or determined by the calling party upon subscribing to a distinctive ring control service.

2. The telephone network of claim 1, wherein the calling party is charged a fee upon the service control point determining the authorization code is valid.

3. The telephone network of claim 1, wherein the calling party is charged a fee upon the call being answered.

4. The telephone network of claim 1, wherein the first service switching point is further operable to issue the query independent of a calling telephone line from which the feature code is received.

5. The telephone network of claim 4, wherein the distinctive ring parameter causes the distinctive ring signal to be applied to the called telephone line independent of services associated with the called telephone line.

6. The telephone network of claim 1, wherein the distinctive ring parameter causes the distinctive ring signal to be applied to the called telephone line independent of services associated with the called telephone line.

7. The telephone network of claim 6, wherein the first service switching point is further operable to issue the query independent of a calling telephone line from which the feature code is received.

8. The telephone network of claim 6, further comprising a second service switching point, the second service switching point serving the called directory number and in communication with the first service switching point over a second communication path, and wherein the first service switching point provides the second service switching point the distinctive ring parameter received from the service control point.

9. A method of processing a call placed by a calling party to a called telephone line in a telephone network, the telephone network comprising a first service switching point, a second service switching point and a service control point, the service control point in communication with the first and second service switching points over first and second communication paths, respectively, the method comprising the steps of:

receiving at the first service switching point an authorization code;

including the authorization code in the query, wherein the authorization code is a unique

code associated with the calling party, and is generated automatically or determined by

the calling party upon subscribing to a distinctive ring control service;

determining at the service control point whether the authorization code is valid or invalid; and

providing the distinctive ring parameter if the authorization code is valid.

10. The method of claim 9, further comprising the steps of charging the calling party a fee if the authorization code is valid.

11. The meted of claim 9, wherein the step of sending the query from the first service switching point to the service control point after receiving the feature code is independent of a calling telephone line from which the feature code is received.

12. The method of claim 11, wherein the step of applying the distinctive ring signal to the called telephone line is independent of services associated with the called telephone line.

13. The method of claim 9, wherein the step of applying the distinctive ring signal to the called telephone line is independent of services associated with the called telephone line.

14. The telephone network of claim 9, further comprising the step of sending from the first service switching point to the second service switching point the distinctive ring parameter received from the service control point if the second service switching point serves the called telephone line.

15. A system for caller control of a distinctive ring, the system comprising:

a first service switching point serving a calling telephone line and being operable to receive from the calling telephone line a feature code and a called directory number associated with a called telephone line, and to issue a query in response to receiving the feature code; and

a service control point in communication with the first service switching point over a first communication path, the service control point being operable to receive the query and issue a response to the first service switching point, the response including a distinctive ring parameter;

wherein upon receiving the response from the service control point the first service switching point processes the call so that upon connection of the call distinctive ring parameter causes a distinctive ring signal to be applied to the called telephone line independent of services associated with the called telephone line;

wherein the first service switching point is further operable to issue the query independent of the calling telephone line;

wherein the first service switching point is further operable to receive an authorization code and include the authorization code in the query; and

the service control point is further operable to determine whether the authorization code is valid or invalid, and provides the distinctive ring parameter only upon determining that the authorization code is valid;

wherein the authorization code is a unique code associated with the calling party.

16. The system of claim 15, wherein the calling party is charged a fee upon the service control point determining the authorization code is valid.

17. The method of claim 15, wherein if the service control point determines the authorization code is invalid the first service switching point processes the call so that upon connection of the call a normal ring signal is applied to the called telephone line.
