摘要:
In a mobile communication system for carrying out packet transmission/reception between a mobile terminal having a power saving mode to reduce a power consumption and a radio base station, a packet type of a packet is judged, and a sleep timer value indicating a time duration since a last packet is transmitted/received until the power saving mode starts is set according to a judgement result. Then, at least one sleep timer for measuring an elapsed time since the packet is transmitted/received is activated, and the mobile terminal is controlled to execute the power saving mode at a timing at which the elapsed time measured by the at least one sleep timer exceeded the sleep timer value.

An object of the invention is to make improvement in the configuration of location registration areas. When a base station 13P is newly installed in a location registration area 30A, the base station 13P recognizes a location of its own with GPS or the like and performs communication with a plurality of surrounding base stations 13Q to select a location registration area 30A to which it should belong, based on the belonging status of the surrounding base stations 13Q and the location of its own. If the base station 13P is located near a boundary between location registration areas and if the surrounding base stations 13Q belong to a plurality of location registration areas, the location registration area to which the base station 13P should belong may be selected so as to average traffics in the respective location registration areas, or the location registration area with the smallest number of base stations belonging thereto may be selected so as to average the numbers of base stations in the respective location registration areas. The base station 13P broadcasts an area identifier of its belonging location registration area 30A to mobile stations under control thereof and starts provision of service thereto.

A water treating apparatus is provided which is capable of producing a hypochlorous acid-containing electrolytic water having a satisfactory sterilizing ability in a household. The water treating apparatus is an apparatus for producing hypochlorous acid in for-treatment water containing a salt by use of an electrochemical reaction which occurs in the for-treatment water when a direct current voltage is applied to at least a pair of electrodes oppositely disposed in the for-treatment water, wherein the direct current voltage to be applied to the electrodes is obtained by smoothing an alternating voltage of domestic use power supply into direct current power of a predetermined voltage, an electrode having titanium covered with a coating containing at least palladium or ruthenium is used as an anode, and at most 90% of the salt added to the for-treatment water is converted into hypochlorous acid by the electrochemical reaction.

A heat exchanger used for a refrigerating cycle has a plurality of grooves formed in the inner surface of a pipe thereof in the flowing direction of a refrigerant. At least two types of grooves which differ in width are used. The pipe also has fins which are coated with a hydrophilic paint that is black in color. This design enables the heat exchanger to provide improved performance.

In a BRE300, an RF interface for transmitting and receiving an RF signal is used for communication with a MDE 200 and a digital signal interface for transmitting and receiving a digital signal in accordance with CPRI is used for communication with BDE 300. The BRE 300 includes a monitoring signal interface configured to notify the MDE 200 of a monitoring signal indicating a state of the radio unit 50. The signal transmitted and received through the monitoring signal interface is a ground signal and is of type different from types of signals transmitted and received by the RF interface and the digital signal interface.
