In a code division multiple access (CDMA) cordless telephone system, CDMA telephone signals are exchanged between a basestation and an operating mobile cordless telephone handset. An upstream signal transmitted by the operating handset is detected at a detection location remote from the basestation by a signal recognition unit, which processes the detected upstream signal to recognize whether the handset is authorized, in which case an identification signal identifying the operating handset as being at the location and as being authorized is transmitted through a signal conduit to the basestation.

[ We claim:] [1.]1. A method of operating a code division multiple access (CDMA) telephone system, which comprises the steps of:transmitting an upstream CDMA telephone signal incorporating a digitally encoded voice signal and handset identification from an operating CDMA mobile handset having an identification code to a basestation;said basestation having a coverage zone for exchanging upstream and downstream telephone signals with said handset and said handset being located within said coverage zone;detecting said upstream CDMA telephone signal at a signal detection location which is spaced from said basestation;processing said detected upstream CDMA telephone signal at said signal detection location to recognize said identification code of said handset and to provide an identification signal indicative of the identity of said handset; andtransmitting said identification signal from said signal detection location to said basestation.
