Abstract: In a portable-terminal usage management method, log distribution conditions are downloaded from an administrative function module to one of a plurality of portable terminals. One of a plurality of communication log storage parts is selected in accordance with the log distribution conditions whenever one of the plurality of portable terminals starts communication. A communication log related to the communication started by the one of the plurality of portable terminals is stored into the selected one of the plurality of communication log storage parts.

Abstract: The present invention relates to a method of rerouting a PVC route on an ATM network by previously defining an alternate route for the PVC route and by switching the PVC route to a previously defined alternate route when a fault occurs in a network element forming the PVC route.

Abstract: A network management device for managing a plurality of network elements has a network element management data acquisition unit for acquiring, in stages, various management data possessed by the network elements when a session with a network element is resumed and when the network management device itself is started up, a rule management table for storing a dependence relationship between an operation and management data necessary to execute the operation, a feasible operation decision processing unit which, when an operation has been specified, refers to the dependence relationship to determine whether management data necessary to execute the operation has been acquired. If the necessary management data has been acquired, a network management execution unit executes network management conforming to the operation.
