<p>A method and an equipment for transferring a transmission signal of a digital mobile communication system as packets (41-46) of a packet network, e.g. the ATM network, the packets comprising a header and a payload. Radio stations (11, 12) place traffic frames (A-H) and/or parts thereof in the payloads of the packets, and the packets are sent to a destination. Previous traffic frames or parts thereof of the same connection are placed in the payload of the packets (41-46) in addition to the latest traffic frame (A-H) formed until the payload of the packet (41-46) is essentially filled. At a combination point (13) the traffic frames (A-H) included in the same packet (41-46) are separated from each other and stored in a buffer memory (26, 27) unless a corresponding traffic frame (A-H) sent by the same radio station (11, 12) is already stored in the buffer memory (26, 27). Even if the packet network lost some packets (41, 42, 45), each buffer (26, 27) comprises an uninterrupted sequence of traffic frames in spite of the loss of packets, and the packets lost by the network do not have to be retransmitted. If parameters representing the quality of the connection are placed in the part of the payload of a packet (41-46) not filled with traffic frames (A-H), the connection point (13) may choose (48) the best traffic frame (A-H) relayed across different branches.</p> |
