Abstract

A cellular cordless telephone (10) operates with both a cordless base station (180) and a cellular base station (190) and cellular control terminal (196). In one embodiment (FIG. 2 ), a cellular cordless telephone (100) includes a cellular transceiver (120), antenna (128), keyboard (140), a display (180), handset (160), and microcomputer (130) together with a cordless transceiver (110) and antenna (118), all of which may be in a single housing. In another embodiment (FIG. 3 ), a cellular cordless telephone (200) includes a cellular telephone (220) and a cordless telephone transceiver (210) which may be a plugable module. Whenever cellular cordless telephone (10) is within range of cordless base station (180), telephone calls may be made over the cordless radio channel or transferred from the cellular radio channels to the cordless radio channel. If the cellular cordless telephone (10) thereafter moves out of range of the cordless base station (180), telephone calls may be made over the cellular radio channels or transferred from the cordless radio channel to one of the cellular telephone channels.

Claims

1. A method of receiving incoming telephone calls in a cellular cordless telephone that has a memory and can receive a call according to a preselected preference of either cellular telephone calls to a cellular telephone number on cellular radio channels of a cellular telephone system or cordless telephone calls on at least one cordless radio channel of a base station coupled to a telephone landline having a landline telephone number in a landline telephone system, said landline telephone number having call forwarding and being call forwarded by the landline telephone system to said cellular telephone number when not answered after a predetermined number of rings, said cellular telephone number having call forwarding and being call forwarded by the cellular telephone system to said landline telephone number when not answered after a predetermined number of rings, the preselected preference and the availability of call forwarding being stored as predetermined information in the memory of the cellular cordless telephone, said method comprising the steps of:

polling the predetermined information in the memory to determine the stored pre-selected preference and the stored availability of call forwarding;

accepting an incoming telephone call when said incoming telephone call matches said stored preselected preference;

ignoring an incoming telephone call when said incoming telephone call does not match said stored preselected preference and when the stored availability of call forwarding has been determined; and

accepting a subsequent incoming call when said subsequent incoming call matches said stored preselected preference.
