20060002382, Jan 5, 2006

Filed:

Jun 30, 2004

Appl. No.:

10/881283

Inventors:

Daniel Cohn - Plano TX, US

International Classification:

H04L 12/66

US Classification:

370356000, 370522000

Abstract:

A cellular wireless core network for establishing calls via dynamic virtual circuit connections includes a source call server exchanging messages with a destination call server in order to determine a destination media gateway. The destination media gateway determines a destination logical ATM component and its logical ATM component address. The destination media gateway returns the destination logical ATM component address to the destination call server, which, in turn, returns the destination logical ATM component address to the source call server. The source call server forwards the destination logical ATM component address to a source logical ATM component. The source logical ATM component sends an Establish Request (ERQ) message to the destination logical ATM component containing the destination logical ATM component address, the source logical ATM component address, and a virtual circuit connection identifier that uniquely defines the virtual connection through the ATM network.

Inventors:

Daniel COHN - Plano TX, US

International Classification:

H04M 3/42
H04M 1/64

US Classification:

379 8813, 37920103, 379 8822

Abstract:

A terminal and a method are described herein for offering termination-side services to a user. In one embodiment, the terminal (e.g., cellular terminal, enterprise or residential wireline device, mobile device) is configured to provide one or more termination-side services (e.g., color ring back tone, voice mail, call diversion, hold before answer) to the user. The terminal is further configured to enable the user to directly setup and manage the one or more termination-side services without interacting with the telecommunication network.

International Classification:

G10L 19/12

US Classification:

704219, 704201, 704E19035

Abstract:

The present disclosure provides systems and methods for dynamically signaling encoder capabilities of vocoders of corresponding communication nodes. In one embodiment, during a call between a first communication node and a second communication node, a control node (e.g., base station controller or mobile switching center) for the first communication node sends capability information for a voice encoder of a vocoder of the first communication node to a control node for the second communication node. As a result, the second communication node is enabled to select and request a preferred encoder mode for the voice encoder of the vocoder of the first communication node based on the capabilities of the voice encoder of the vocoder of the first communication node.

Northern Telecom Limited - Montreal

International Classification:

H04Q 730
H04Q 738
H04M 1100

US Classification:

455433

Abstract:

A terminal coupled to an intelligent telecommunication network may invoke dynamically modifiable subscriber services by transmitting information to a switch to which script files, each containing programming script needed to initiate a calling feature or other advanced subscriber service and a criteria statement used for triggering execution of the programming script, were downloaded thereto from a home location register where the script files may be added, deleted or otherwise modified by a system administrator. A program execution module residing at the switch compares the received information to the criteria statement for each script file downloaded thereto and executes the programming script of the script file having a criteria statement which matches the received string of digits. In wireless systems, the script files are downloaded to an MSC whenever a roaming terminal registers therewith.

Assignee:

Nortel Networks Corporation - Montreal

International Classification:

H04J 312

US Classification:

370522

Abstract:

A method and system for implementing a communications network having configurable control mechanisms for the identification and transference of particular types of communications data. Detection points are established within the communications network, wherein particular types of communications data transferred through the detection points may be identified. Removable configurable control mechanisms are associated with the detection points mechanisms that manage the transference of communications data through the detection points, such that the removable configurable control mechanisms may be easily replaced and updated without deconstructing the communications network or extensively delaying communication services within the communications network. The communications network can include a wireless or wireline communications or a combination thereof. The configurable control mechanisms include triggers within calls or communication transactions which can be armed to transfer control and call-related information to external nodes that may be composed of off-board service platforms.
