摘要： PURPOSE:To reduce the reception station cost by dividing a region, where the condition, the position, or the like of a mobile station should be recognized, into plural blocks by the coverage area of each reception station and setting and overlapping respective coverage areas to gather information of the condition, the position, or the like of the mobile station in many blocks by a small number of distributed reception stations. CONSTITUTION:When a taxi business region is divided into blocks D, E, and F, blocks DE, EF, FD, and DEF of overlapping zones are set in overlapping parts of these blocks. When a taxi 6 in the business region exists in the block DE, condition information of the vacant vehicle number or the like of the taxi is originated and is received by a distributed reception station close to the taxi 6. That is, it is received by first and second distributed reception stations 1 and 2, which can receive it, and is transmitted to a radio car operation room 4 through a circuit 5. The same operation is performed for the other blocks, and information is gathered in white parts of blocks D, E, and F in the same manner as conventional.
