Method of adjusting frequency of cellular radio repeater
First Claim
1. A method of adjusting the radio frequency of a repeater in a cellular radio network, the repeater being configured to amplify radio signals of a bi-directional radio connection between at least one base station and a subscriber terminal at least at one particular radio frequency, the method comprising:
- monitoring the radio signals transmitted by the at least one base station;
automatically tuning to amplify signals of the particular radio frequency on the basis of information included in the radio signals; and
monitoring a predetermined base station identified by a base station identity code, the monitored radio signals comprise a broadcast control channel including information on operating frequencies of the predetermined base station.

Abstract
The invention relates to a method of adjusting the radio frequency of a repeater (302) in a cellular radio network. The repeater (302) amplifies radio signals (170) of a bi-directional radio connection between a base station (100) and a subscriber terminal (150) at least at one particular radio frequency. In accordance with the invention, the repeater (302) monitors the radio signals (170) transmitted by at least one base station (100). The repeater (302) automatically tunes to amplify the signals (170) of the particular radio frequency on the basis of information included in the radio signals (170) it has monitored. The monitored radio signals (170) include a control channel, for example a broadcast control channel BCCH, comprising information on the operating frequencies of the base station (100). Monitoring means (404) are preferably similar to a subscriber terminal (150).
