PROBLEM TO BE SOLVED: To provide a base station area information service system that can acquire area information of an area which is regionally limited using a simple operation and effectively utilize information suitable for the regionally limited area. SOLUTION: First, a base station distributes data to a receiver side unidirectionally can acquire area information of the regionally limited area a simple operation; secondly, a hierarchical structure or a data structure including a link destination address is adopted for data to attain entry using a simple operation; and thirdly, saving primarily data provided to the receiver side to the base station to avoid the problem due to deficiency in a memory capacity of the receiver side and to attain entry by a simple operation, and unidirectionally distributing the saved data to the receiver side enables the receiver side to distribute data to a limited area. Fourthly, by including communication protocol to the distribution data, inter-communication between receiver sides is attained, to effectively utilize information suitable for the regionally limited area. |
