Patent number: 9942417Abstract: A method for providing local cordless service comprises the steps of receiving subscriber neighborhood zone selection input so that a mobile telephone equipped subscriber may place or receive calls for a fixed rate, for example, per month without having to pay radio frequency air time charges any time they are located within their selected subscribed-to zones. If the subscribed-to zones are adjacent to one another and the mobile subscriber roans from one zone to another, the subscriber may continue their fee call uninterrupted and without paying air time charges. However, when the subscriber roans outside their subscribed-to zones they may be switched from the present local cordless services to conventional personal communications services and pay air time charges. However for an active call, No air-time charges are incurred as the user transitions between the cellular/DPCS environment and the local cordless service environment.Type: GrantFiled: February 20, 2017Date of Patent: April 10, 2018Assignee: AT&T INTELLECTUAL PROPERTY II, L.P.Inventors: Albert Chow, Spencer Wang, Wenchu Ying

Patent number: 8711735Abstract: In an internet telephony system, toll-free service and the calls that are accepted and paid for can be specified by the IP telephony system user to be limited according to the calling party's identity, time of day, day of week or other criteria. Data that is used to screen or filter incoming calls is programmed into a call manager by the IP telephone system user's broadband residential gateway. Using such a system the user can carefully screen calls that are paid for and more closely control telecommunications service costs. More generally, the user has the ability to store predefined call handling criteria, which may be executed by the broadband residential gateway and/or the call manager.Type: GrantFiled: June 8, 2012Date of Patent: April 29, 2014Assignee: AT&T Intellectual Property, II, L.P.Inventors: Fen-Chung Kung, Jesse Eugene Russell, Anish Sankalia, Spencer Wang, Hopeton Walker

Patent number: 7805141Abstract: A method and apparatus for providing telephone call hand offs between a local cordless service and a different wireless cellular service such as a macro-cellular service. The local cordless service may be configured such that a mobile telephone equipped subscriber may place or receive calls for a fixed rate, for example, per month without having to pay radio frequency air time charges any time they are located within their selected subscribed-to zones. If the subscribed-to zones are adjacent to one another and the mobile subscriber roams from one zone to another, the subscriber may continue their free call uninterrupted and without paying air time charges. However, when the subscriber roams outside their subscribed-to zones they may be switched from the present local cordless services to conventional personal communications services and pay air time charges.Type: GrantFiled: April 19, 2007Date of Patent: September 28, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: Albert Chow, Jinman Kim, Spencer Wang, Wenchu Ying

Patent number: 7760711Abstract: A method of billing a variable bit rate communication between a first terminal and a distant terminal to a broadband subscriber permits changing billing parameters during a call in real time in response to user inputs including user requested changes in quality of service, changes in data rate and changes in preferred service provider. A variable bit rate communication to be billed has a variable quality of service related to the degree of utilization of a plurality of different networks. The billing method comprises the steps of i.) receiving user identification data at a first terminal and data representing a required bit rate and a default quality of service selected by the user, ii.) verifying the user identification data to be associated with the broadband service subscriber, iii.) determining least cost alternative network resources available for achieving the communication at the user selected default quality of service and the required bit rate, iv.Type: GrantFiled: September 21, 2007Date of Patent: July 20, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: Fen-Chung Kung, Anish Sankalia, Hopeton Walker, Spencer Wang

Patent number: 7734908Abstract: Communication information transmitted in the broadband communication system may be in a packet format and secured using encryption techniques, for example encryption software, including a means for providing an initial security key and updated security keys to the various pieces of communication equipment located throughout the broadband communication system. When communication equipment, for example a gateway, is first registered with, for example, an IP central station, the IP central station assigns an initial encryption key to the gateway that is assigned and retained by a server, for example a call manager server, and the gateway (e.g., broadband residential gateway). This initial encryption key may be used to establish a secure two way communication between two pieces of communication equipment as an originating point communication equipment and a terminating point communication equipment.Type: GrantFiled: October 26, 2004Date of Patent: June 8, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: Fen-Chung Kung, Jesse Eugene Russell, Hopeton Walker, Spencer Wang

Patent number: 7558251Abstract: A broadband communication system including an Internet Protocol Telephony Network and public switched telephone network, including apparatus and methods for placing a call on hold in a way that significantly reduces the amount of network bandwidth utilized by the call while the call is on hold. When a call is placed on hold, embodiments of the architecture of the telephony network of the present invention allows the network to essentially “forget” about the call placed on hold. In other words, a call that is on hold may require very little, or even zero, bandwidth within the telephony network. Accordingly, the total necessary bandwidth capacity of the telephony network may be smaller than it would be if calls on hold were to consume precious network bandwidth as is found in existing telephony systems.Type: GrantFiled: September 14, 2004Date of Patent: July 7, 2009Assignee: AT&T Intellectual Property II, L.P.Inventors: Laura Huang, Fen-Chung Kung, Jesse Eugene Russell, Hopeton Walker, Spencer Wang

Patent number: 7451694Abstract: A roll pressing machine includes a support, a stationary roller unit disposed on the support and having a stationary roller, a self-modulating roller unit, a swingable body, and a biasing unit. The self-modulating roller is disposed movably on the support and has a moving roller adapted for pressing a blank against the stationary roller. The moving roller is movable toward or away from the stationary roller to vary a gap between the stationary and moving rollers. The swingable body is coupled to the moving roller. The biasing unit includes a pusher member pushing resiliently the swingable body so that the moving roller moves toward the stationary roller.Type: GrantFiled: September 17, 2007Date of Patent: November 18, 2008Assignee: Boltun CorporationInventor: Spencer Wang

Patent number: 7075918Abstract: A residential private branch exchange (PBX) allowing IP telephones, analog telephones and computers to connect to an IP communication network. A broadband residential gateway (BRG) PBX provides residences with multiple phone lines capability and the implementation of complex calling features traditionally associated with complex and expensive business PBX systems. The BRG PBX provides an open architecture interface minimizing problems during installation and operation, minimizes interoperability problems across multi-vendor equipment platforms and may provide customers with an option to bypass the local telephone company's high cost infrastructure. The BRG PBX may also provide a range of services from basic calling with few features to highly sophisticated calling features servicing multiple phone lines to the residence. The BRG PBX may be configured to connect multiple BRG PBX systems together in a Local Area Network (LAN) or Wide Area Network (WAN) configuration.Type: GrantFiled: December 30, 1999Date of Patent: July 11, 2006Assignee: AT&T Corp.Inventors: Fen-Chung Kung, Jesse Eugene Russell, Spencer Wang, Hopeton Walker
