Neighborhood cordless service call handoff
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.
