ABSTRACT:
A cellular telecommunication system (CTS) is provided that supports the operation of a radiotelephone (RT) in cellular and cordless modes. The CTS includes operating features that are dependent upon the intrasystem location of the RT. The CTS includes a mobile telephone switching office, a plurality of land stations, a plurality of cells, a plurality of zones defined by one or more cells, a plurality of local regions defined by one or more cells, and a cordless base station located within one of the cells. The land stations transmit zone identification (ZNID) signals and local region identification (LRID) signals, which the RT receives and compares to one or more ZNID codes and one or more LRID codes, respectively. The RT displays its intrasystem billing zone location and initiates communication with the cordless base station in response to the received ZNID and LRID signals, respectively.
