摘要
The invention relates to ATM systems, and particularly to mobility and call control management therein. A wireless ATM network comprises at least on ATM switch, and base stations connected to the ATM switch by a user-network-interface interface. In addition, at least one controlling network element of a conventional PLMN network, such as a mobile telephone exchange or a base station controller, which is responsible for the mobility management and call control, is connected to the ATM network by the UNI interface. A permanent virtual channel is provided between the base station and the controlling PLM element for PLM-specific signalling (signalling related to, for example, call control, mobility management or radio resource management). The ATM switch therebetween forwards the signalling without interpreting it in any way. The PLMN element remotely controls the ATM switch to switch a virtual connection between the base station and another point according to the ATM standards.
