A method and apparatus use existing datafill information from macrocells to turn-up the cell site. A cell site includes a global position positioning system (GPS) receiver configured to determine a current location of the cell site. A transceiver subsystem in the cell site manages a wireless communication interface, and a controller, coupled to the GPS receiver and the transceiver subsystem. The controller is configured to send the current location of the cell site to a cell site manager, receive cell site identification data for existing macrocells and virtual macrocells from the cell site manager, and selects candidate macrocells based on a selection algorithm until one is validated by the switching center. Datafill information associated with the validated macrocell to create datafill entries for the cell site.
