20080200118 | Communication System and Communication Method - A communication system and a communication method for permitting a user of a cell-phone to receive data in a non-service area via an MFP. When the communication condition between a base station and a cell-phone becomes bad, the base station sends a map showing the current position of the cell-phone and the locations of nearby MFPs to the cell-phone. The user of the cell-phone selects one from the MFPs on the map and notifies the base station of the selected MFP. The base station sends an e-mail addressed to the cell-phone to the selected MFP, and the MFP stores the e-mail therein. The user of the cell-phone makes an access to the MFP by short-distance wireless communication to receive the e-mail. | 08-21-2008 |
