A base station includes a monitoring unit that monitors whether a supply of electrical power to a first other base station that forms another communication area that is overlapped with a communication area formed by the own station is stopped, and a wireless communication unit that sends, when the supply of the electrical power to the first other base station is stopped, first key data by using a first channel and that sends, after sending the first key data, second key data that is the same as the first key data and a transmission regulation notification indicating that call regulation is performed on the own station by using a second channel.

Base station, communication terminal, and call regulation control method

A group communications switching method is disclosed. The method includes the steps of: maintaining a voice call between a first subscriber terminal and a second subscriber terminal when it becomes necessary to perform group communications while the voice call is in progress; starting a group communications call by the first subscriber terminal so as to call at least a group communications member other than the first subscriber terminal and the second subscriber terminal; and disconnecting the voice call between the first subscriber terminal and the second subscriber terminal when the group communications call is established.

Group communications switching method, subscriber terminal and server used for the method

A dynamic traffic control method is disclosed that controls traffic in a radio network system where a radio network controller causes plural radio base stations to change radio outputs. The method comprises a step of measuring a channel utilization rate of each of cells of the radio base stations every predetermined period, a step of predicting whether the rate of a first cell of the cells reaches an implementation level, at which radio output control over the first cell is required, in a next period based on a movement of the rate in the past if the channel utilization rate of the first cell is at a warning level, and a step of reducing the radio output of the first cell and increasing the radio output of a second cell adjacent to the first cell if the rate of the first cell is predicted to reach the implementation level.

The known flourinated layer has usually a thickness of from 1000 to 3000 angstroms. After the forced oxidation of metal, the forcibly oxidized surface is flourinated. As a result of the preceding forcing oxidation, a 1 &mgr;m or more thick fluorinated layer is formed on the surface of the metal.

Fluorinated metal having a fluorinated layer and process for its production

A surface-fluorinated metal oxide particulate comprising a metal oxide particulate selected from titanium, aluminum, silicon, silver, copper, zirconium, zinc, tin, germanium, tantalum and the like, being reacted with fluorine and a process for manufacturing such surface-treated metal oxide particulates are disclosed. The process allows easy and efficient fluorination of the surface of metal oxide particulates in any desired ratio. The surface-fluorinated metal oxide particulates of the present invention are useful as an additive for weatherable paints, weatherable resins, cosmetics and the like. Surface-fluorinated titanium oxide particulates obtained by fluorination of titanium oxide particulates have improved light stability, water-repellence, and dispersibility as compared with conventional titanium oxide particulates and maintains surface smoothness of the resin-coated substrate when contained in high concentrations in thermoplastic resins as a white pigment with water content being controlled in a specified range and prevents the occurrence of troubles at the time of melt extrusion coating for obtaining resin-coated substrates.
