The invention relates to a method for reconfiguring a cellular radio network connection comprising a network part having a connection to a mobile station through at least one radio bearer. According to the invention, a first party of the connection, i.e. the network part or the mobile station, sends a second party of the connection, i.e. the mobile station or the network part, a reconfiguration request message concerning at least one radio bearer. The second party of the connection possibly replies to this by sending the first party of the connection a reply message to the radio bearer reconfiguration request message. The radio bearer reconfiguration request message comprises at least one radio bearer identifier and, for example, bearer quality of service of the radio bearer in question. The possible reply message comprises at least one radio bearer identifier and possibly also bearer quality of service assigned to the radio bearer in question, or a cause for a failed reconfiguration of the radio bearer in question.

Method for reconfiguring a cellular radio network connection

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.
