Abstract
Abstract A method for providing a 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 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. 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. Associated apparatus comprises an IBS for automatically changing radio frequency channels as the subscriber roams within a subscribed-to neighborhood zone, roams to another subscribed-to zone or roams outside a subscribed-to zone. Subscribers may choose to use their mobile identification number, their current directory telephone number for wired public switched telephone service or obtain a new directory number.
