Patent number: 7693273Abstract: A method of signalling in an AIN, in which in an SSP, the initial message of a new transaction is addressed to a Service Global Title (SGT). The SSP translates that SGT to a first address of the first choice SCP. The SCP responds with an acknowledgement message which has a second address of the SCP as its source address, and includes the Nodal Global Title (NGT) of that SCP. The SSP sends subsequent messages for that transaction addressed to that NGT, and the SSP translates that NGT to the second address of the SCP. When the SCP is taken out of service, the first address is made unavailable, so the SSP sends new initial messages to the second choice SCP, but subsequent messages for existing transactions may still be sent to the second address of the first choice SCP. When all existing transactions have ceased, the SCP is taken out of service.Type: GrantFiled: February 20, 2003Date of Patent: April 6, 2010Assignee: British Telecommunications plcInventor: Douglas H Rice

Patent number: 7403947Abstract: A method and system for providing computer-network related information about a calling party. First, the called party receives a telephone number of a calling party. The called party's customer premises equipment (CPE) or elements in a telephone network then use the telephone number to index a database, which contains combinations of telephone numbers and computer-network addresses. Once the calling party's computer-network address is retrieved, calling-party-customized information present at the computer-network location specified by the computer-network address can be sent to and displayed on the called party's CPE. Also, the calling party's telephone number can be sent to an application in the computer network, causing the calling-party-customized information to be automatically displayed on the called party's CPE.Type: GrantFiled: April 1, 2003Date of Patent: July 22, 2008Assignee: AT&T Knowledge Ventures, L.P.Inventor: Arnold M.

Patent number: 7394897Abstract: A method and system for routing service calls made from lines resold to a competitive service provider includes advanced intelligent network and standard switching functionality. The call may be made into an AIN service switching point (60) or a non-AIN switch (62-64). All calls are routed to an AIN hub (190), such as a service switching point, via a trunk group. The AIN or non-AIN switch may access a line class code table (160-164) to determine the proper routing information. Calls made from resold lines are routed to the AIN hub (190). Once the call is routed to the AIN hub, a trigger (187) provisioned on the AIN hub and assigned to the incoming trunk group causes the hub to suspend the call and launch a query to a service control point (200). The query includes the directory number of the resold calling line and the originally dialed number. The SCP (670) accesses a data-base (675) containing directory numbers for resold lines and identifiers for competitive service providers.Type: GrantFiled: November 4, 1998Date of Patent: July 1, 2008Assignee: AT&T Delaware Intellectual Property, Inc.Inventors: James C.

Publication number: 20080152091Abstract: The present invention provides methods, apparatuses, and computer media for re-routing outgoing calls from a communications terminal. A call routing module selects a set of re-routing plug-ins. One of plug-ins determines re-routing information for an outgoing call based on call information in accordance with a priority list. A priority order for offering a call event to a re-routing plug-in is determined from at least preference list. A preference list may be configured by a subscriber through a user interface. Also, preference lists and re-routing plug-ins may be downloaded over a communications channels. Another re-routing plug-in is offered a call event if a first re-routing plug-in is not able to re-route an outgoing call. One of a plurality of communications systems is selected for re-routing an outgoing call. A communications systems supporting a close-proximity technology may be selected when a communications terminal is sufficiently near the communications system.Type: ApplicationFiled: December 26, 2006Publication date: June 26, 2008Applicant: Nokia CorporationInventor: Veli-Pekka Kivimaki
