Publication number: 20080248814Abstract: A location visit detail service, typically provided by a wireless carrier to a subscriber, includes a portable wireless device, a location identification means and a central processor. The central processor periodically receives location data generated by the location identification means. The central processor data transforms the location data into time and position data pairs that identify the location of the portable wireless device at a particular time. Through a geographic information system database, the position data is converted to street address data. The details data is provided by the wireless carrier to the subscriber, which can use the details data to provide a summary report describing the activity of the service person. This summary report can be used for preparation of bills or for gathering statistics on (individual or group) service person efficiency. Alternatively, the wireless carrier can prepare the report that is then transmitted to the subscriber.Type: ApplicationFiled: September 25, 2007Publication date: October 9, 2008Applicant: AT&T BLS Intellectual Property, Inc., formerly known as BellSouth Intellectual Property, Inc.Inventor: Sunil H.

Patent number: 7388949Abstract: Methods and systems are disclosed for audibly announcing information associated with a calling party in an advanced intelligent network comprising a service switching point, a service control point and a services node. The service switching point is adapted to suspend calls directed to an audio caller identification service and to forward information concerning the calling and called parties to the service control point. The service control point is adapted to direct the call to a selected services node. The services node sends a query to retrieve information concerning the calling party from the service control point. If necessary, other service control points may be queried for the information. While the aforementioned processing is occurring, the calling party continues to hear a ringing signal. When the aforementioned information is retrieved, the service directs a second call to the called party.Type: GrantFiled: December 28, 2000Date of Patent: June 17, 2008Assignee: AT&T Delaware Intellectual Property, Inc.Inventors: Sunil H.

Patent number: 7277922Abstract: Method and apparatus are disclosed for contacting users based on the completion of an online session, such as an Internet session. A user begins an online session by logging into an access provider, such as an Internet Service Provider. Upon completion of the online session, the access provider can store online session data that describes the online session. The online session data may include such information as the identity of the user (e.g., a phone number, an address, and so forth) and the time the online session ended. This online session data can be processed by a caller in order to identify users to call. The caller may be the access provider or a third party, such as a telemarketer. The online session data may be processed in various manners. The online session data may be compared to data of failed calls to identify users who could not be contacted before, but that may now available based on the completion of their online sessions.Type: GrantFiled: April 10, 2001Date of Patent: October 2, 2007Assignee: AT&T BLS Intellectual Property, IncInventor: Sunil H.

Patent number: 7194080Abstract: A Service Control Point (SCP) has a call list associated with the main telephone number of a called party. When a calling party attempts to contact the called party by calling the main number, but cannot reach the main number, a Service Switching Point (SSP) fires a trigger. One trigger is a T_No_Answer trigger, which is fired in response to a call to the main number that is not answered within a predefined number of rings. Another trigger is a T_Busy trigger that is fired in response to a call to the main number that is made when the main number is busy. Each trigger causes the SCP to access the call list and to cause the SSP to ring an alternative telephone number associated with the main telephone number. If this attempt to reach the called party also fails, then the SSP again fires the trigger and an attempt is made to connect the calling party to the next number on the call list.Type: GrantFiled: June 29, 2001Date of Patent: March 20, 2007Assignee: BellSouth Intellectual Property CorporationInventors: James A.

Patent number: 7120239Abstract: Call detail service is provided using a trigger that only activates after the disposition of a telephone call is known, for example, a T-Busy and/or a T_NoAnswer. When a telephone call encounters the T-Busy or T_NoAnswer trigger a terminating central office switch attempts to complete the call. If the call is not completed because it is busy or not answered, the information related to the call is sent to a service control point. The service control point creates a call information record. The call information record is sent to a service management system that used the call information record to create a call detail report. Using the T_Busy and/or T_NoAnswer triggers eliminates the need to collect data for every telephone call to determine which calls are not completed because they are not answered or busy. As a result processing complexity and storage requirements are significantly reduced.Type: GrantFiled: August 17, 2004Date of Patent: October 10, 2006Assignee: BellSouth Intellectual Property Corp.Inventor: Sunil H.
