First Claim
Patent Images
1. A method of queuing calls to a subscriber of queuing services accessed through a subscriber line, the method comprising:
- provisioning Call Forward on Busy Line on the subscriber line to permit detecting a call to the subscriber line at a local switch connected to the subscriber line;
if the subscriber line is busy, forwarding the call to an intelligent peripheral within an Advanced Intelligent Network (AIN) telecommunications system;
queuing the call to the subscriber in the intelligent peripheral;
determining that the subscriber line is not busy by dialing the subscriber line from the intelligent peripheral; and
if a call is queued in the intelligent peripheral and the subscriber line is determined to be not busy, connecting the call to the subscriber with the subscriber line.

Abstract
An inexpensive alternative for call queuing is provided by queuing calls at an intelligent peripheral within an AIN telecommunication system. A call to the subscriber line is detected at a local switch supporting the subscriber line. If the subscriber line is busy, the call to the subscriber is queued in the intelligent peripheral.

9. A system for queuing subscriber calls within an Advanced Intelligent Network (AIN) telecommunications system, each subscriber call placed by a caller to a subscriber line, the system comprising:
-
a local switch servicing the subscriber line, the local switch including Call Forward on Busy Line functionality provisioned on the subscriber line, the Call Forward on Busy Line functionality forwarding any subscriber call received for the subscriber line when the subscriber line is busy; and an intelligent peripheral within the AIN system operative to; (a) receive any forwarded subscriber call from the local switch; (b) if queue slots are available in the intelligent peripheral, queue the received subscriber call; (c) place a busy check call to the subscriber line; (d) drop the busy check call if the busy check call is forwarded back to the intelligent peripheral from the local switch; and (e) connect a queued subscriber call to the busy check call if the subscriber line is not busy. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A method for queuing subscriber calls comprising:
-
provisioning a subscriber line with Call Forward on Busy Line functionality at a local switch servicing the subscriber line; receiving a subscriber call destined for the subscriber line at the local switch; if the subscriber line is busy, forwarding the received call to a Direct Inward Dial telephone number on an intelligent peripheral via the Call Forward on Busy Line functionality; receiving the forwarded call at the intelligent peripheral; and queuing the forwarded call at the intelligent peripheral if the intelligent peripheral has at lease one available queue slot; and placing a call from the intelligent peripheral to determine if the subscriber line is still busy. - View Dependent Claims (20, 21, 22, 23, 24, 25)

26. A method for queuing subscriber calls comprising:
-
queuing at least one subscriber call in an intelligent peripheral; placing a busy check call from the intelligent peripheral to a subscriber line; receiving the busy check call in a local switch servicing the subscriber line; if the subscriber line is busy, forwarding the busy check call back to the intelligent peripheral through Call Forward on Busy Line functionality implemented in the local switch; disconnecting the busy check call if the intelligent peripheral receives back the forwarded busy check call; and connecting a queued subscriber call with the busy check call if the subscriber line is not busy.
