Abstract: A remote machine uses a process control unit to monitor a process for a Web browser program. When the process for the Web browser program starts to operate, an operating time therefor starts to be measured. When the operating time reaches a predetermined time, the process for the Web browser program is forcefully terminated. After that, unless the remote machine 2 is rebooted, that is, unless a RAM is cleared, the process for the Web browser program is forcefully terminated immediately after its start.

Abstract: For the first use of an authentication device, a remote machine makes a query of an address of a local machine to be permanently assigned to the remote machine, to which the authentication device is connected, to a management server. In response to the query, the management server determines the local machine to be permanently assigned to the remote machine and notifies the remote machine of an address of the local machine. The remote machine remotely controls the local machine specified by the address notified from the management server.

Abstract: The invention provides a radio communication system searching method for a portable telephone terminal for selecting, when a plurality of radio communication systems having different carrier frequencies are present in a same area, a suitable one of the radio communication systems. The searching method is improved in that radio communication systems can be searched in order beginning with a radio communication system which is the most advantageous to the user to eliminate the problems of a disorder of company types of radio communication systems and system selection involved in adjacent systems of a same company type.

Abstract: A time correcting method includes steps of receiving notifying information from a base station, the notifying information including an identification number identifying the base station, selecting a time differential information item corresponding to the identification number from a table which indicates a relationship between identification numbers identifying base stations and time differential information items in service areas of the respective base stations, and correcting a present time using the selected time differential information item.

Abstract: In a first aspect of the invention, when it is expected to disconnect a booster during a call, the station class mark is changed to that applicable when a portable telephone is used as an independent unit in accordance with a key input from the user before the initiation of the call. In a second aspect of the invention, the telephone number of the remote party is stored in a memory during a call. When a connection or disconnection of a booster is detected, the call is terminated, and a redialing operation is automatically performed using the stored telephone number. In a third aspect of the invention, when the connection of a booster is detected during a call, an instruction is given to the booster to operate in a portable telephone mode. In a fourth aspect of the invention, when the connection or disconnection of a booster is detected during a call, a request to change the station class mark is sent to the base station.

Abstract: When frequencies are being scanned to seize a control channel immediately after the end of a call, if there arises a call request, the call request is stored, and a calling operation is automatically initiated after a control channel has been seized. When a call request is stored, if a predetermined length of time has elapsed before a control channel is seized, the stored call request is discarded.

Abstract: A control apparatus for controlling a memory unit having an electrically erasable nonvolatile memory for storing information used in a process in an electrical equipment and a flash memory storing a processing program for executing the process in the electrical equipment.

Abstract: A first ID code ESN (electronic serial number) for apparatus identification and a second ID code MIN (mobile identification number) such as a telephone number are stored beforehand in a non-volatile memory of a mobile telephone terminal. The mobile telephone terminal transmits these ID codes to a network at the time of communication, and whether or not this set of first and second ID codes has been registered is discriminated on the network side. Communication is allowed if the ID codes have been registered.
