Patent number: 7257404Abstract: 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: August 9, 2004Date of Patent: August 14, 2007Assignee: AT&T Corp.Inventors: Albert Chow, Jinman Kim, Spencer Wang, Wenchu Ying

Patent number: 7181207Abstract: A method for providing a local cordless-type 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 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-type 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: July 6, 2005Date of Patent: February 20, 2007Assignee: AT&T Corp.Inventors: Albert Chow, Spencer Wang, Wenchu Ying

Patent number: 6819945Abstract: The instant invention discloses a method and system for providing a novel wireless centrex service that untethers subscribers from the immobility associated with traditional desktop telephones. Essentially, the present invention extends the benefits of wireless voice and data services to subscribers having a need to move within a plurality of localities such as business and hospital campuses. In accordance with the invention, a wireless telephone subscriber can use a standard cellular/PCS telephone as a wireless extension of their desktop phone, while in the proximity of a miniature radio base station capable of communicating with the PCS/cellular telephone. The advantage of such a system is that a subscriber can use the same cellular/PCS telephone that provides service in the public network in the wireless centrex environment. Additionally, the wireless centrex system provides services and features which are similar to those offered to regular centrex telephone subscribers.Type: GrantFiled: December 13, 1999Date of Patent: November 16, 2004Assignee: AT&T Corp.Inventors: Albert Chow, Jinman Kim, Spencer Wang, Wenchu Ying
