Method and system for preserving service node resources and reducing clipping effect
First Claim
1. A method for making simultaneous ringing calls comprising:
- detecting an incoming call to a first telephone by a service switching point;
determining by a service control point associated with the service switching point an operational status of a service node;
checking by the service control point a busy/idle status of a second telephone associated with the first telephone if the service node is operational; and
generating a first outgoing call to the first telephone and a second outgoing call to the second telephone by the service node if, but only if, the first telephone and second telephone are idle.

Abstract
The present invention provides telephone line subscribers the benefits of simultaneous ringing service without wasting telephone network resources. When a simultaneous ringing service subscriber'"'"'s wireline telephone (the primary telephone) receives an incoming call, a service switching point connected to the primary telephone sends a query to a service control point. The service control point then checks the busy/idle status of the primary telephone as well as the subscriber'"'"'s wireless telephone (the secondary telephone). If the primary and the secondary telephones are idle and can receive the call, the service control point instructs the service switching point to forward the call to a service node. Otherwise, the service switching point is authorized to terminate the call. When the service node receives the call from the service switching point, it generates two calls simultaneously: one to the primary telephone and one to the secondary telephone. As soon as one of the primary and the secondary telephones is picked up, the service node immediately cancels the call to the telephone that has not answered and connects the caller to the telephone that has answered. The service node then remains on the communication link for several seconds before withdrawing from the communication to minimize a “clipping effect” associated with the use of the service node.

19. An advanced intelligent network telecommunication system comprising:
-
a first service switching point connected to a primary telephone of a subscriber, the primary telephone having a primary telephone number; a service control point having a database associating the primary telephone number with a secondary telephone number of a secondary telephone of the subscriber; means for detecting an incoming call to the primary telephone; means for determining an operational status of a service node associated with the service control point; and means for checking busy/idle status of the primary telephone and secondary telephone, wherein when the incoming call to the primary telephone is detected, the service control point determines the operational status of the service node, and the service control point checks the busy/idle status of the primary telephone and secondary telephone if the service node is operational, and the service control point forwards the incoming call to the service node for generating a first outgoing call to the primary telephone and a second outgoing call to the secondary telephone if, but only if, both the primary telephone and the secondary telephone are idle. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)

- 27. A telecommunication system comprising a service node, a first telephone, a switch associated with the first telephone, and a second telephone, wherein when the first telephone receives an incoming call from a caller, the switch forwards the incoming call to the service node if the service node has been determined to be operational, the service node then generates a first outgoing call to the first telephone and a second outgoing call to the second telephone if both the first telephone and the second telephone have been determined to be idle, and when one of the first telephone and the second telephone answers, the service node makes a connection between the caller and the telephone that answers, maintains the connection for a predetermined duration, and withdrawing from the connection after the predetermined duration has expired.

29. A method for providing simultaneous ringing service comprising:
-
associating a first telephone number of a wireline telephone and a second telephone number of a wireless telephone in a database accessible by a service control point; detecting an incoming call to the wireline telephone; determining by the service control point an operational status of a service node associated with the service control point; checking by the service control point busy/idle status of the wireline telephone and the wireless telephone if the service node is operational; generating by the service node a first outgoing call to the wireless telephone and a second outgoing call to the wireline telephone if, but only if, both the wireline telephone and the wireless telephone are available to receive calls; and after one of the wireline telephone and the wireless telephone answers one of the first outgoing call and the second outgoing call, connecting the incoming call to the telephone that has answered and canceling the remaining one of the first outgoing call and the second outgoing call. - View Dependent Claims (30, 31, 32, 33, 34, 35)
