1. A method for dynamically allocating a data channel, comprising the steps of:
- (1) sending by an originating user a first request for bandwidth message to a first switching point in a common channel signaling network, said first request for bandwidth message identifying said originating user, a destination user, and an amount of bandwidth required in a proposed connection;
(2) sending by said first switching point a first bandwidth connection message to a first switch, said first bandwidth connection message identifying a connection at said first switch between incoming channels from said originating user and a first set of channels that are outgoing from said first switch;
(3) sending by said first switching point a second request for bandwidth message toward a second switching point in said channel signaling network in a communications rotate to said destination, said second request for bandwidth message identifying said originating user, said destination user, and said first set of channels;
(4) sending by said second switching point a second bandwidth connection message to a second switch in a communication to said destination user, said second bandwidth connection message identifying a connection at said second switch between said first set of channels and a second set of channels that are outgoing from said second switch;
(5) repeating steps (3) and (4) until a destination switching point and a destination switch connected to said destination user are reached;
(6) sending by said destination switching point a third request for bandwidth message to said destination user, said third request for bandwidth message identifying said originating user and a third set of channels in a proposed connection; and
(7) sending by said destination user a bandwidth accepted message to said destination switching point if said destination user accepts said proposed connection.

Abstract
A system and method for dynamically provisioning digital data services. Connection setup for the digital data services is accomplished through messages transported on a common channel signaling network. These messages permit an originating user to automatically provision a data communications connection that has a dynamically adjustable bandwidth.

4. A method for modifying an existing connection between an originating user, an originating switch, a terminating switch, and a terminating user, wherein the existing connection includes a plurality of channels, the method comprising the steps of:
-
(1) receiving a message in the originating switch from a common signaling network that identifies a first set of incoming channels that are sought to be added or deleted from the existing connection; (2) connecting or disconnecting, at the originating switch, the first set of incoming channels from a first set of outgoing channels; (3) receiving a message in the terminating switch from said common signaling network that identifies a second set of incoming channels that are sought to be added or deleted from the existing connection; (4) connecting or disconnecting, at the terminating switch, the second set of incoming channels from a second set of outgoing channels; and (5) modifying by the originating user and the terminating user the existing connection, wherein said step of modifying is performed without breaking the existing connection.

5. A communications system comprising:
-
a plurality of switching points in a common channel signaling network, wherein users send requests for connections to the plurality of switching points; a plurality of switches, wherein the plurality of switches are connected to the plurality of switching points; an originating user, connected to a first switching point within the plurality of switching points; and an end user, connected to a second switching point within the plurality of switching points, wherein the originating user sends a first request for bandwidth message to a first switching point within the plurality switching points in which the first request for bandwidth message identifies the originating user, the end user, and an amount of bandwidth required in a proposed connection;
wherein the first switching point sends a first bandwidth connection message to a first switch within the plurality of switches in which the first bandwidth connection message identifies a connection at the first switch between incoming channels from the originating user and a first set of channels that are outgoing from the first switch;
wherein the first switching point sends a second request for bandwidth message toward a second switching point within the plurality of switching points in a communications route to the end user in which the second request for bandwidth message identifying the originating user, the end user, and the first set of channels;
wherein the second switching point sends a second bandwidth connection message to a second switch within the plurality of switches in a communications route to the end user in which the second bandwidth connection message identifies a connection at the second switch between the first set of channels and a second set of channels that are outgoing from second switch, wherein bandwidth connections messages and requests for bandwidth connection messages arc sent until a communication route to the end user is formed. - View Dependent Claims (6, 7, 8)
