Method and system for dual ringing of a centrex line and a wireless extension of the centrex line
First Claim
1. A method for dual ringing of a Centrex line and a wireless extension of the Centrex line using an advanced intelligent telecommunication network comprising a service signal point and a service node, the method comprising:
- (a) receiving a call at a service signal point (SSP) assigned to a Centrex line;
(b) routing the call from the SSP to a service node coupled with the SSP; and
(c) with the service node, initiating a first call to a wireless communication device associated with the Centrex line and a second call to the Centrex line.

Abstract
A method and system are provided for dual ringing of a Centrex line and a wireless extension of the Centrex line. With dual ringing functionality, a single destination number dialed by a calling party results in ringing of both a Centrex line and a wireless extension of the Centrex line. In one preferred embodiment described herein, the dual ringing functionality is implemented with a network element (e.g., a service node) separate from a switch (e.g., a service signal point). In this way, the dual ringing functionality is available to users of any end office switch that uses the separate network element—not only to those users of a particular type of end office switch. Furthermore, unlike switches, network elements, such as service nodes, typically do not require vendor approval for modification. Additionally, the dual ringing functionality of these preferred embodiments is switch independent and provides an open platform.

5. A method for dual ringing of a Centrex line and a wireless extension of the Centrex line using an advanced intelligent telecommunication network comprising a service signal point, a service control point, and a service node, the method comprising:
-
(a) receiving a call at a service signal point (SSP) assigned to a Centrex line;
(b) suspending processing of the call and launching a query to a service control point (SCP) coupled with the SSP;
(c) in response to the query, determining whether a wireless communication device associated with the Centrex line is available; and
(d) if the wireless communication device associated with the Centrex line is available;
(d1) launching a routing message from the SCP to the SSP instructing the SSP to route the call to a service node coupled with the SSP;
(d2) routing the call from the SSP to the service node; and
(d3) with the service node, initiating a first call to the wireless communication device and a second call to the Centrex line. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 16, 17, 19, 20, 21, 22)

15. A system for dual ringing of a Centrex line and a wireless extension of the Centrex line, the system comprising:
-
a service signal point (SSP) assigned to a Centrex line, the SSP operative to receive a call placed to the Centrex line, suspend processing of the call, and launch a query;
a service control point (SCP) coupled with the SSP, the SCP operative to receive the query launched from the SSP and determine whether a wireless communication device associated with the Centrex line is available; and
a service node coupled with the SSP, the service node operative to initiate a first call to the wireless communication device and a second call to the Centrex line in response to the wireless communication device being available.
