    Abstract: 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.
