Controlling a subscriber station on a direct mode channel
First Claim
1. A method for controlling a subscriber station operating on a direct mode channel in a radio system, the method comprising:
- providing the radio system with a radio network with at least one base station, a plurality of subscriber stations having respective identifiers, and at least one mobile relay repeater station having a coverage area;
operating at least two of the subscriber stations on a at least one direct mode channel;
the at least one mobile relay repeater station forwarding traffic on separate radio paths between the at least one base station and those of the subscriber stations which are operating on the direct mode channel;
the at least one mobile relay repeater station maintaining, in the mobile relay repeater station, data as to the identifier of each the at least one direct mode channel on which respective ones of the subscriber stations operate;
the at least one mobile relay repeater station maintaining information as to the identifiers of those of the subscriber stations which are operating on the at least one direct mode channel in the coverage area of the mobile relay repeater station, the maintaining of information as to the identifiers of those of the subscriber stations including, by the mobile relay repeater station;
listening to the operating of respective ones of the subscriber stations on the at least one direct mode channel;
collecting the identifiers of the respective ones of the subscriber stations from transmissions of the subscriber stations; and
storing the collected identifiers of the respective ones of the subscriber stations operating on the at least one direct mode channel in a database of the mobile relay repeater station.

Abstract
The present invention relates to a method and radio system for controlling a subscriber station (MS1) operating on a direct mode channel in a radio system, said radio system comprising a radio network (SwMi) with at least one base station (BS) and subscriber stations (MS1), and further, at least one repeater station (RS), which forwards traffic between said at least one base station (BS) and the subscriber stations (MS1) operating on the direct mode channel. To control the subscriber stations operating on the direct mode channel, information on the identifiers of subscriber stations operating on the direct mode channel in the coverage area of the repeater station (RS) is maintained in said repeater station (RS).
