Proximity systems in conjunction with radiocommunication systems are described. Mobile stations include proximity detectors which recognize proximity signals transmitted by a proximity system. This recognition triggers a search, for example, for a private radiocommunication control channel. In this way, mobile stations have a mechanism which is independent of public radiocommunication cell characteristics for recognizing the presence of a private radiocommunication system.

1. A mobile station comprising:a first receiver for receiving signals over an air interface within a range of frequencies, a second receiver operating concurrently with said first receiver for receiving a proximity signal indicating the presence of a radiocommunication system, said proximity signal not being within said range of frequencies; and a processor for processing said received signals and said received proximity signal, wherein receipt of said proximity signal triggers said processor to tune said first receiver to a control channel associated with said radiocommunication system.
