Title: WIRELESS COMMUNICATION SYSTEM, CONNECTION METHOD, SERVICE AREA CONSTRUCTION APPARATUS, AND SERVICE AREA CONSTRUCTION PROGRAM
Abstract:
In a wireless network (101), when a wireless terminal (200) which is performing wireless communication by being connected to a certain cell via a base station (300) moves to an adjacent cell in the same service area, the connection destination cell of the wireless terminal (200) is switched to the cell to which the wireless terminal (200) moves. A service area construction apparatus (400) constructs, for the wireless network (101), two service areas consisting of a non-virtual cell area and a virtual cell area which overlap each other. The non-virtual cell area is a service area where adjacent cells use different frequencies for wireless communication. The virtual cell area is a service area where adjacent cells use the same frequency for wireless communication. The service area construction apparatus (400) selects or switches a service area to accommodate the wireless terminal (200), according to the type or movement amount of the wireless terminal (200).
