Abstract: A method for operating a radio telecommunications system comprising a mobile station and one or more cell site units capable of communicating by radio with the mobile station on at least two communication channels; the method comprising: the mobile station receiving signals on each of the communication channels; and the mobile station determining an estimate of the level of interference with signals on each of the communication channels.

Abstract: The invention relates to a method and an arrangement for configuring an indoor base station for a cellular mobile telecommunications network. According to an advantageous embodiment of the inventive method, a mobile communications means is used to scan possible transmission frequencies on-site to find out free frequencies to operate on, and to transmit the results of scanning of the frequencies to the indoor base station and to choose proper parameters for the indoor base station. An arrangement according to an advantageous embodiment of the invention comprises an indoor Base Transceiver Station, mobile communications means for scanning frequencies and to find free frequencies and a Base Station Controller for controlling the base station.

Abstract: Disclosed herein is a radio system and method for routing a subscriber's call via a moving base station. The radio system includes at least one moving base station. A moving location area is formed using the service areas of the moving base station. A control unit of at least one operator is dedicated to controlling the operation of the moving base stations belonging to the moving location area. Calls made by a subscriber in a service area of the moving base station are routed from the subscriber terminal via a moving base station, a relay satellite and a ground earth station to one dedicated control unit. Calls to a subscriber located in the moving location area are routed from one dedicated control unit via a ground earth station, a relay satellite and the moving base station to the subscriber terminal.
