Abstract: The present invention introduces a system, which comprises a telecommunication network structure, which can be called as an intelligent combination of Push-To-Talk (i.e. Direct Mode Operation, DMO) communication technique and cellular network application. The DMO can be set as a preferred choice if it is available. The subscriber devices retransmit (i.e. forward) the data message further until the message reaches the called subscriber terminal. The total cumulative hop between subscriber terminals may comprise both DMO-based hops and cellular connections. ID means are provided, and telemetric information can be sent from the terminals. The invention allows emergency information submissions from the terminals, and forced broadcast information from an administrator to the terminals as well. Dynamic Talk Groups (DTG) can be defined based on geographic locations on each registered user.

Abstract: The invention relates to an arrangement for implementing voice transmission using a subscriber line of a public switched telephone network in a system having a concentrator network part connected to the subscriber line for connecting a plurality of subscriber lines to a data transmission network. The concentrator network part includes voice traffic processing equipment, which are arranged to perform a conversion between analog voice signals of the subscriber lines and IP voice packets. It further includes transceiver and multiplexing equipment for transmitting and receiving data transferred over analog subscriber lines, and packet traffic switching equipment, which are arranged to receive and transmit packets between the voice traffic processing equipment and a core network and between the transceiver and multiplexing equipment and a core network.
