Patent number: 7929674Abstract: Embodiments of the present invention relate to billing for services in an Advanced Intelligent Network (AIN) environment. A first call is received at a service node from a service switching point located in the AIN. A second call is established through the service switching point to a called party. The first call is bridged with the second call and the bridged call is monitored for signaling information. The bridged call is processed based on the monitored signaling information. A billing module is created for the processed call at the service node. The billing module may include service values related to billing information for the processed call. The processed call may be merged back into the service switching point and the created billing module for the processed call may be sent to the service switching point for ultimate delivery to a billing system.Type: GrantFiled: July 9, 2007Date of Patent: April 19, 2011Assignee: AT&T Intellectual Property II, L.P.Inventors: Devinne H. Brown, Hwey Chang, Romel R. Khan, Michael Koptiw, Antoinette Rule, Tejanand Sarju

Patent number: 6771762Abstract: An AIN system having a service switching point (SSP), a service control point (SCP) and an intelligent peripheral (IPe) is disclosed. A calling party makes a call to a called party which results in a trigger signal at the originating SSP. The trigger signal causes the SSP to access the SCP which, in turn, sends a Send_to_Resource message to the SSP. In response to the Send_to_Resource message, the SSP establishes a first connection to an IPe, whose functionality is required. The IPe establishes a second connection carrying a second call to the called party, the first and second calls being connected at the IPe. The IPe subsequently requests that the SSP merge the first and second calls. In response, the call between the called party and the calling party is connected via the SSP, thereby releasing the IPe connections formerly used to connect calling and called parties.Type: GrantFiled: July 13, 2000Date of Patent: August 3, 2004Assignee: AT&T Corp.Inventors: Hwey Chang, Pamela Lilly DeFazio, Romel R.

Publication number: 20030108179Abstract: An enhanced intelligent network telephony system includes at least one service nodes (SN) imbued with special routing, message handling and billing capabilities. Using the Extension Parameter in an Analyze-Route message, a service control point (SCP) provides a set of service node parameters including service node identification and message content. The SN receives, processes and implements the services corresponding to the message content. Included among these may be announcement IDs corresponding to announcements, such as advertisements, that the SN can initiate at an intelligent peripheral for playing to calling and called parties, and routing numbers which the SN can use to route a particular destination under certain conditions as per the service needs. The SN is also able to request an originating switch to update an Automated Message Accounting (AMA) record created at the originating switch, using information created by the SN.Type: ApplicationFiled: December 10, 2001Publication date: June 12, 2003Inventors: Hwey Chang, Pamela Lilly DeFazio, Romel R.

Patent number: 5894478Abstract: The present invention encompasses an apparatus and method for supporting multiple wireless data communication networks between a wireless communications device and a fixed communications device or another wireless communications device. Two network elements compose the physical apparatus, a protocol converter and a router. Upon receiving packet data from a fixed communications device, a router will locate a destination wireless communications device. The router will then convert the packet data to a format usable by the wireless data network that the wireless communications device is currently using for wireless access. After conversion, the router will perform actual transmission of the packet data to the correct destination wireless network. Once the converted packet data is received by the wireless network base station, it will be transmitted via RF to the destination wireless communications device.Type: GrantFiled: July 24, 1996Date of Patent: April 13, 1999Assignee: Lucent Technologies Inc.Inventors: Farhad Barzegar, Chi-Hwey Chang, Albert Chow, Gregory M.
