Abstract: 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.

Abstract: A communication apparatus monitors a communication situation of a communication performed using each of a plurality of security associations established between the communication apparatus and a counterpart apparatus, and stores information indicating the communication situation. When a first security association in the plurality of security associations is disconnected, the communication apparatus determines whether the counterpart apparatus uses the disconnected first security association, based on the information. When the counterpart apparatus uses the first security association, the communication apparatus reestablishes a second security association which supersedes the first security association.

Abstract: 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.

Abstract: 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.
