IMPROVEMENTS IN, OR RELATING TO, ATM TRANSMISSION BY RADIO

摘要

A telecommunications system has an ATM-network and at least one radio link. A subscriber equipment can be connected to said ATM link by an ATM-adapted radio modem. The subscriber equipment includes an ATM-card containing an ATM-layer and an AAL-layer. The ATM-adapted radio modem has a mobile part and a fixed part. The mobile part is linked to a subscriber equipment by a UNI-interface. The fixed part is linked to an ATM-node, of an ATM network, by a UNI-interface, and is physically located in a radio base station. The subscriber apparatus is adapted for connection, either to said ATM-adapted radio modem, or directly to said ATM network, by a fixed link. Complete AAL-PDUs for traffic routed via said ATM-adapted radio modem are not created in the ATM-adapted radio modem.
