A network management apparatus in a mobile communication network holds a communication quality index in a normal operation and periodically receives input of a communication quality measurement result from a radio base station control apparatus. When a connection failure count f with respect to a connection request count a of each radio cell is obtained as a measurement result, letting pbe the call loss rate in the normal operation, an upper probability B of a binomial distribution representing the connection failure count becomes larger than f is obtained (step). The negative logarithm of the upper probability B is obtained as the score of the degree of abnormality (step). Anomaly of communication is detected when the score of the degree of abnormality exceeds a predetermined threshold value (stepsand). After that, maintenance control is executed in accordance with the calculated score of the degree of abnormality, thereby appropriately avoiding a fault of the communication system. This allows to calculate the degree of abnormality from the measurement result of the communication quality index in the mobile communication network in consideration of the statistical reliability and execute maintenance corresponding to the degree of abnormality.

Disclosed is a travel-time prediction apparatus that is capable of making a mid-term prediction of travel time accurately by combining present conditions and statistical information. The apparatus includes a travel-time transition pattern database storing travel-time transition patterns obtained by statistically processing past time-series data of each road link according to type of data. Upon accepting a travel-time transition pattern corresponding to a specified link and day type from the database, the apparatus calculates conversion parameters of a travel-time transition pattern for which an error between the travel-time transition pattern and a sequentially input travel-time time-series data will be reduced, and then makes a prediction using a prediction function obtained by converting the travel-time transition pattern by the calculated conversion parameters. The calculated predicted value and the conversion parameters are distributed as traffic information.

When the temperature of an engine and a main battery is low at the time of activating a vehicle system, an ECU starts the engine in advance and outputs a running permission signal after completion of engine startup. At this stage, the ECU suspends a defect diagnosis operation on a subsidiary load and feedback-controls the DC/DC converter by setting the voltage control value to a level lower than the output voltage from the subsidiary battery and at least the lower limit of the operating voltage of the ECU. The ECU feedback-controls the DC/DC converter by setting the voltage control value to a level of at least the output voltage of the subsidiary battery in response to completion of engine start-up. Then, the suspension of the defect diagnosis operation on the subsidiary load is canceled and a running permission signal is output.

First, two subsystems are connected with each other via a communication cable and then recognize physical connection between the two subsystems. Next, each one of the two subsystems ignores signals from the other subsystem for a predetermined time period after recognition of the physical connection. Then, the two subsystems execute the connection procedure and after that, establish data communication between the two subsystems.

To provide an interface device and method of controlling power to achieve reduction in power consumption by presetting the transceiver in the standby state. When the physical layer (PHY)makes a transition to a low power consumption mode, a standby signal (standby) for instructing the optical transceiverto preset it into the low power consumption mode is brought into active and is output thereto. When the optical transceiver receives said standby signal, it is brought into the standby mode which is the low power consumption mode.
