There is provided a method for a flow control to a mobile communication network in which an ATM virtual channel established between a first base station having a radio zone in which a mobile station exists and a terminating ATM node to which a remote station with which the mobile station communicates is connected. The first step of the method is to queue, in an ATM node, incoming cells to be sent to a second base station having a radio zone when the mobile station is handed over to the radio zone of the second base station. The second step of the method is to stop queuing and send the incoming cells queued in the ATM node to the second base station after the mobile station is handed over.

Method for flow control, node and communication network employing the flow control

A multiplex transmission system according to the present invention is provided with a plurality of multiplex nodes which are connected in parallel with two common buses so that data are transmitted between the nodes. A receiver circuit of each multiplex node includes a passive potential detector section and bias sections. In case of any trouble on the buses, in this multiplex transmission system, the passive potential detector section detects the respective passive-mode potentials of the buses, controls the bias sections in accordance with the detected passive potentials, and sets input potentials within a predetermined range, thereby enabling data transmission between the multiplex nodes.
