Abstract

The present invention relates to a technique of providing a push delivery service. A data center transmits attribute information on positions and radii of areas A through J to a user station. The user station compares the attribute information with a self-predicted position to predict that the user station itself lies in the area A through J. When the user station confirms that the user station lies in the area A through J, and requests the data center for delivery information attached to the area A through J on the basis of a result of confirmation. The data center transmits delivery information to the user station in response to the request. The user station knows itself in one of plural push delivery areas A through J, and decreases the frequency of positioning and pinpoints delivery of information such as shop advertisements is possible.
