Abstract:
1. A dedicated-short-range-communications system comprising: a base station apparatus configured to in response to type information indicating a type of data available to each of a plurality of applications installed on an external device, said type information including a contents type identifier indicating a type of data available to the application, specify and send out data, which the application can use, based on the type information; and a mobile communication station configured to pre-register type information indicating a type of data, a type of application, and a buffer size of a buffer memory of the mobile communication station to be used for data divisions by a base station apparatus, and a maximum size of contents, configured to transmit the type information to said base station apparatus when entering a communication area of said base station apparatus, configured to receive data, which said application installed in said external device can use, from said base station apparatus, and configured to transfer the received data, divided into several pieces at the base station apparatus, each having a size equal to or smaller than the buffer memory size of the buffer memory of the mobile communication station to said external device, in accordance with types of applications and a type of data to be reproduced, during the connection in dedicated-short-range-communications with the base station apparatus, and configured to specify the external device that is the destination of the transfer of the data based on the type information, wherein the mobile communication station includes a data storage unit configured to store the data received from said base station apparatus, and the mobile communication station is configured to re-transfer the data stored in said data storage unit to said external device when said mobile communication station receives a request for re-execution of the data from said base station apparatus, said request for re-execution including a type of application.
