Abstract
A cellular communication system comprises an access point () which supports an underlay cell of a first cell on an underlay frequency using another frequency. A proximity detector () detects user equipment () in response to a wireless transmission therefrom, which uses a different transmission technology from a transmission of the cellular communication system. In response to the proximity detection, the access point () temporarily transmits a pilot signal on the first cell frequency. The user equipment () is then switched to the access point () and the underlay frequency in response to a detection indication from the user equipment () indicating that the pilot signal has been detected. Following the switch the access point () terminates the transmission of the pilot signal.
