摘要： A connection control method is achieved by receiving from a first terminal, a call request for a communication with a second terminal to notify the call request from a connection control server to an application server; and executing at least a program to receive the call request from the connection control server, to request a connection state data of the second terminal to a storage server in response to the received call request. A connection control instruction for the first and second terminals is issued to the connection control server when there is no connection state data of the second terminal in the storage server or the second terminal in a free state. A connection control between the first and second terminals is performed by the connection control server in response to the connection control instruction; and the connection state data of each of the first and second terminals is stored in the storage server when the connection state between the first and second terminals is changed.

摘要： In an information processing apparatus, a connection control method performs a connection control of communication terminals through a network. A call is received from a calling one of communication terminals. The reception of the call is notified to a setting unit which sets the connection control data. The connection control of the communication terminals is performed in response to an instruction from the setting unit. A control is performed to provide a content data for the calling communication terminal before completion of the connection control.

摘要： Provided are a wireless communication method, a base station, a wireless communication system and a communication apparatus whereby an interference power is calculated from an estimated propagation channel estimation result and the transmission power is controlled based on the interference power or the interference is suppressed by controlling the directivity, thereby increasing the transmission capacity. A propagation channel estimation circuit performs propagation channel estimation from a response signal transmitted from a terminal station and estimates a propagation channel estimation result. An interference power calculation circuit measures each interference power from a signal of each sub-carrier received by each of wireless units, and calculates an interference power for each sub-carrier from the propagation channel estimation result estimated by the propagation channel estimation circuit. When the calculated interference power is equal to or more than a predetermined threshold, an interference suppression signal generation circuit changes the transmission power and generates an interference suppression signal.

摘要： This radio communication method is used to perform spatial multiplexing communication between cells in the overlap cell environment. In the MU-MIMO overlap cell environment, when a null is formed between a radio base station and a radio terminal station belonging to different cells, a first set of a “call signal” and a “response signal” is used to perform mutual detection with the radio base station and the radio terminal station belonging to different cells, and then a null is formed so as not to cause interference of radio waves between the radio base station and the radio terminal station belonging to different cells. At this time, the addresses of the radio base station and the radio terminal station are used to discriminate whether the radio base station and the radio terminal station belong to the same cell or different cells.

摘要： A wireless communication system includes a first wireless station including antenna elements, transmission units corresponding to the antenna elements, and a transmission directivity control unit that controls transmission directivity of the antenna elements, and second wireless stations each including a reception power measurement unit that measures a reception power. The transmission directivity control unit determines the transmission directivity of each of the antenna elements so that a signal does not reach a particular second wireless station among the second wireless stations. The transmission units generate wireless signals using the transmission directivity. The antenna elements transmit the generated wireless signals. The reception power measurement unit measures the reception power in a period that is set so that a signal does not reach the particular second wireless station by using the directivity, and detect the presence or absence of interference caused by the low accuracy of channel information.
