US Patent:

6343292, Jan 29, 2002

Filed:

Sep 3, 1998

Appl. No.:

09/146419

Inventors:

Adam Roach - Dallas TX
Paul Tidwell - Garland TX

Assignee:

Ericsson Inc. - Research Triangle Park NC

International Classification:

G06F 1700

US Classification:

707101, 707102, 707104

Abstract:

A development tool for creating telecommunication subscriber services or other operations. The tool reads a subscriber service logic diagram containing function primitives which define the service and creates data structures containing text descriptions of primitive operation and parameters pertaining thereto. The tool then examines the data structures and determines the appropriate text descriptions for the function primitives and corresponding parameters, based upon parameter values assigned by a user in creating the subscriber service logic diagram. The tool also validates parameters against available constraints. The text descriptions are then ported into the subscriber service logic diagram, thereby clarifying the operation of the subscriber service defined by the logic diagram.

Assignee:

Telefonaktiebolaget LM Ericsson (publ) - Stockholm

International Classification:

H04L 12/18

US Classification:

370261, 370432

Abstract:

A system and method for establishing a conference call in an Internet Protocol (IP) telecommunications network between a conference owner and a plurality of other conference participants. The IP network includes a conference server and at least one Call State Control Function (CSCF). The CSCF includes a Presence and Instant Messaging (PIM) server that notifies the conference server when participants are present and available. A first user is registered with the conference server as the conference owner, and the owner identifies the conference participants and provides criteria for initiating the conference. The conference server identifies each participant's serving CSCF, and sends a request to A each CSCF to notify the conference server when served participants are present and available. When the predefined number of participants are present and available, the conference server initiates the conference call.

International Classification:

H04M 3/42

US Classification:

370260, 370261

Abstract:

A system and method of providing a subscriber service to service users in a telecommunications network. In networks utilizing Session Initiation Protocol (SIP) control signaling for call setup and control, the SIP REGISTER message is modified to indicate service capability information and optionally a traffic load indication for service providers. The REGISTER message is sent to a modified Presence and Instant Messaging (PIM) server that stores presence information and the service capability information for registered service providers. The PIM server then notifies subscribing service users of the identity of the service provider that is registered on the network. The PIM server may utilize the traffic load information to balance the traffic load between service providers by providing users with the identity of the service provider that is the most lightly loaded.
