Abstract: A base station system includes a controller and a plurality of radio apparatuses, each of the radio apparatus being multistage-connected to each other and being configured to communicate with the controller, wherein a transmission frame between the radio apparatuses and the controller includes a plurality of blocks, wherein one or several blocks are allocated to a shared area for a data signal that is shared among two or more of the radio apparatuses, and other blocks are allocated to an individual area for a data signal that is not shared among two or more of the radio apparatuses, wherein each of the radio apparatuses is configured to select whether the block that is used for a radio area which is provided by the own radio apparatus is set to be a block that is allocated to the shared area, or a block that is allocated to the individual area.

Abstract: A radio communication system including a base station apparatus which includes a first communicable area; and a terminal apparatus which connects to and performs radio communication with the base station apparatus in the first communicable area, wherein the base station apparatus includes a determination unit which decides a destination of the terminal apparatus based on a changeable movement condition according to sizes of the first, a second, and a third communicable areas or power residual quantity of the terminal apparatus transmitted from the terminal apparatus, when the terminal apparatus moves from the first communicable area to the second or the third communicable area whose size is different from the first communicable area and which is overlapped with a part or all of the first communicable area; the terminal apparatus includes a reception unit which receives the information of the decided destination.

Abstract: A call processing control unit establishes communication with a first communication network by using a normal interface, and upon receiving a communication request using a second communication network from the first communication network, activates an emergency interface and establishes communication with the second communication network by using the emergency interface. A wireless communication unit and a baseband processing unit communicate with a first terminal device using the first communication network, connect the first terminal device to the first communication network via the call processing control unit and the normal interface, and when the call processing control unit receives a communication request, communicate with a second terminal device using the second communication network and connects the second terminal device to the second communication network via the call processing control unit and the emergency interface.

Abstract: A wireless communication network area designing method for placement and dimensioning of wireless base station formed by a three-sector configuration is provided. The method includes reducing cell radius of existing sites to half, adding a new site to an intermediate point between adjacent existing sites, aligning the antenna azimuth angle of the new site to that of the existing sites, and setting a cell radius of the new site to be the same as the cell radius of the existing sites in the reduced cell radius.
