Abstract

A wireless device may receive a BA-list from a wireless service provider. Before removing any cell frequencies already stored in the wireless device, the wireless device may determine if the BA-list is complete. If the BA-list is not complete, the cell frequencies already stored in the wireless device may be retained, and the cell frequencies received in the BA-list may be added to the storage. However, if the BA-list is complete, the cell frequencies already stored in the wireless device may be removed if they are not in the BA-list.
