摘要： The invention relates to a method for allocating control channels in a radio system comprising base stations (101) and subscriber stations (102, 103) communicating with the base station on control and traffic channels. To make the control channel operation more efficient and to avoid interference, traffic channels are allocated for control channel use so as to distribute the control channel operation between a greater number of channels, the channels allocated for control channel use being indicated to the subscriber stations (102, 103), and control channel operation is performed on the control channels allocated in a distributed manner.

摘要： 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).

摘要： The present invention relates to a method and radio unit for assigning transmission turns to a radio unit (RU2) wishing to operate on a direct mode channel (f1). To assign the transmission turns in a controlled manner, said radio unit (RU2) monitors the quality of the traffic (101) conducted on the direct mode channel, and if the quality of the traffic (101) falls below a predetermined value, said radio unit (RU2) starts to transmit its transmission (120) on said direct mode channel.

摘要： The invention relates to a method for controlling a subscriber station (MS1, MS2) communicating on a direct mode channel (102, 103) in a radio system, comprising at least one base station (BS1) communicating via channels and subscriber stations (MS1, MS2, MS3). To guide a subscriber station to a desired channel at a desired moment, the radio system (MX) sends (101) to the subscriber station (MS1) on the direct mode channel a communication information message (104) determining for the subscriber station (MS1) the moments and the identifiers of the channels at and on which the radio system (MX) communicates with the subscriber station (MS1) on the direct mode channel, said subscriber station (MS1) stores the information contained in said received communication information message (104) in its memory, the subscriber station (MS1) communicating on the direct mode channel (102, 103) moves at said moment determined by the communication information message (104) to said channel to be used and communicates with the radio system (MX; BS1) on said channel.

摘要： A method for establishing an expanded group call in a mobile communication system comprising group call groups formed by mobile stations (401), a network infrastructure comprising at least one exchange (402), base stations and the telecommunication connections between them, and a group call database for maintaining data concerning group calls. In the method, an expanded group call set-up facility concerning the first group call group is activated in group call database, the facility expanding the group call to concern at least one other group call group, the network infrastructure receives a group call set-up request (405) concerning the first group call group, the network infrastructure checks wether an expanded group call set-up facility has been activated for the first group call group, calls (407, 408) the mobile stations (401) of the first group call group and the mobile stations (404) of at least one other group call group to the expanded group call to be established, and guides the mobile stations to communicate on one traffic channel at each base station of the expanded group call.

摘要： A group call method, a system controller and a subscriber station (200) in a radio system comprising a plurality of base stations and subscriber stations (200). In order for a subscriber station (200) to be able to select (207, 208) the group call in which it will participate from among a plurality of group calls while participating in a first group call, group call data are transmitted to the subscriber station during the first group call, by means of which data the subscriber station (200) can engage (210) in another ongoing group call, whereby the subscriber station (200) continues to participate in the first group call or, if it desires, selects (207, 208) another group call from among the group calls whose group call data have been transmitted to the subscriber station (200) and whose group call identifiers are simultaneously displayed on the display of the subscriber station (200).

摘要： A method for digital semi-duplex transmission. To allow transmission of information to subscribers during the transmitting permission of one of the subscribers, a selected number (N-1) of blocks are transmitted during a time period shorter than the original total duration (t) of the blocks from a subscriber (MS A) having the permission to transmit to a base station (BS) having the permission to receive; the base station (BS) having the receiving permission utilizes the original total duration (t) of the blocks reduced by the actual transmission period of the blocks and by a first and a second guard period (301, 302) for transmitting reverse information (203) and time synchronization information (202) to the subscriber having the transmitting permission; and the base station (BS) having the receiving permission transmits information during at least one of said guard periods (301, 302) to at least one subscriber (MS B) having no transmitting permission.
