ABSTRACT:
A cordless telephone system (300) comprises a portable station (305), a first base station (301) and a second base station (310). The first base station (301) communicates with the portable station (305) over a communication channel (441) when the portable station (305) is located within a first geographic coverage area (311). The second base station (310) communicates with the portable station (305) over a communication channel (441) when the portable station (305) is located within a second geographic coverage area (313). The first base station (301) includes a controller (302) adaptively configured to be a master controller (302). The second base station (310) includes a controller (308) configured to be slave controller (308) responsive to the controller (302) of the first base station (301) being adaptively configured to be the master controller (302). The master controller (302) communicates with the slave controller (308) over a communication path (315) to coordinate communications between the portable station (305) and at least one of the first base station (301) and the second base station (310) when the portable station (305) is located within the first geographic coverage area (311) and the second geographic coverage area (313), respectively. The cordless telephone system (300) advantageously provides an expandable geographic coverage area for a relatively low cost when the number of portable stations are relatively small and the communication traffic is relatively low.
