摘要:
An apparatus and method for permitting temporary use of a telephone number which promptly permit temporary use of a different telephone number without requiring a telephone installation fee. Virtual telephone number notification unit assigns a virtual telephone number to a subscriber terminal at the request of the subscriber terminal, and virtual telephone number registration unit registers the thus-assigned virtual telephone number in association with connection information on the subscriber terminal. In response to call initiation by another subscriber terminal by means of the virtual telephone number, call connection unit refers to the virtual telephone number registration unit to read out the connection information associated with the virtual telephone number and, based on the connection information, connects the calling subscriber terminal to the first-mentioned subscriber terminal.

A system is provided for enabling a subscriber using a credit call service to utilize a telecommunication service subscribed by the subscriber himself or herself. The credit call service system is provided with a service switcher station for registering telecommunication service information for identifying the telecommunication service that each terminal subscribes, a service controller for registering the telecommunication service information of the telecommunication service that the subscriber who subscribes the credit call service subscribes by himself or herself, and a service information replacement unit for replacing the telecommunication service information registered in the service switcher station by the telecommunication service information registered in the service controller upon the receipt the credit call service request from the subscriber. As a result, the subscriber may receive the telecommunication service that the subscriber subscribed, irrespective of the telecommunication service that the used terminal subscribes.
摘要:
In a method and device which prevent unnecessary accounting from being performed when a communication deteriorated state occurs in a mobile terminal, a communication deteriorated state is detected in a state where a location registration is performed to a mobile radio communication network, a duration of the communication deteriorated state is detected, and cut of the duration from a duration of accounting is notified to the mobile radio communication network. With the notification, the mobile radio communication network changes accounting for the mobile terminal in the communication deteriorated state. Also, as the above-mentioned communication deteriorated state, there is e.g. a call disable state, a communication disable state during a voice/packet communication, or a communication disconnection state.

In a method and a device, and a mobile communication system by which a connection switchover between wireless network control devices can be performed with a connected base station being maintained in order to avoid a congestion when the congestion occurs in one of the wireless network control devices within a mobile communication network, network management information indicating congestion states of all wireless network control devices is acquired from a core network within the mobile communication network, a wireless network control device list is prepared in which a higher priority is assigned to the wireless network control devices in ascending order of congestion degree based on the network management information when a call request is received from one mobile terminal through a base station, the wireless network control device list is notified to the mobile terminal through the base station, and the mobile terminal is enabled to select one of the wireless network control devices as a connecting destination.
摘要:
A terminal appliance having a sensor for detecting information on a work target appliance with physical quantities, a first electronic tag which records the information on the work target appliance, a read/write unit for reading/writing the information in the first electronic tag, and information in a second electronic tag which records the personal information on the user, and an arithmetic-logic processing unit for making the work target appliance usable only when the information on the work target appliance and the read personal information on the user coincide with information stored in the first electronic tag and the second electronic tag in advance, the information on the work target appliance being identified based on the physical quantities detected by the sensor.
摘要:
A remote maintenance system has a monitoring computer for monitoring a facility and a monitoring center computer for maintenance management. The monitoring computer has a database for storing image data of the monitored facility. The monitoring center computer a database for storing CAD data for the monitored facility. The monitoring center computer provides coordinates to the image data sent from the monitoring computer, and superposes the image coordinate data and CAD coordinate data for the CAD. The center computer locates a needed maintenance location on the basis of the result of the superposition processing.

摘要:
A remote maintenance system is comprised of: a monitoring computer for monitoring a facility; and a monitoring center computer for using maintenance management. The monitoring computer has a database for storing image data of the monitored facility. The monitoring center computer includes: a database for storing CAD data for the monitored facility. The monitoring center computer provides coordinates to the image data sent from the monitoring computer, and superposes the image coordinate data and CAD coordinate data for the CAD. And the center computer locates a needed maintenance spot on the basis of a result of the superposition processing.
摘要:
A gas turbine performance analysis system includes a performance computation module for receiving an actual measured value of an inlet air temperature introduced to a compressor, a compressor pressure ratio, and a flow rate of fuel supplied to the gas turbine, and for calculating and outputting values of the gas turbine's power output and exhaust temperature based on these actual measured values. A performance estimation module evaluates the performance of the gas turbine based on the deviation between the values of power output and exhaust temperature outputted from the performance computation module and the actual measured values of power output and exhaust temperature. An adjustment module calculates a corrected value of the fuel flow rate based on the actual measured values of inlet air temperature, compressor pressure ratio and fuel flow rate, and inputs the corrected fuel flow rate value into the performance computation module.
