Radio data communication method
First Claim
1. A radio data communication method for radio-transmitting a file from a transmitting device to portable terminals, the portable terminals having memory means for storing a file, said method comprising the steps of:
- (a) converting, in the transmitting device, a file including data other than data in a previously determined specific code set into message data in a message format made up of data in the specific code set;
(b) radio-transmitting the message data from the transmitting device; and
(c) carrying out reverse-conversion in a portable terminal by preparing, based on the received message data in message format, a file equivalent to the file in the transmitting device, and storing the file in the memory means,wherein, in the step (a), the file is converted into updating data that is message data indicative of a part that has been changed and content how the part has been changed, and in the step (c), the part, of the file stored in, the memory means, that is to be changed is updated in accordance with the updating data,further comprising the step of displaying the changed part of the updated file in a form of display that is different from others that have not changed.

Abstract
According to a conventional pager generally avalable, mere characters and symbols can be transmitted and received. In addition thereto, since code sets that can be transmitted and received are limited, data other than messages can not be transmitted and received. However, information management section of the present invention, when transmitting and receiving of data, such as schedule data, including codes other than the code sets, the data should be converted into data in a form of message before carrying out the tranmitting and receiving. Therefore, it is possible to transmit and receive a variety of data prepared in a form other than in a form of message. When transmitting of data, only the part that has been changed is transmitted while the information management section of the addressee changes only the part corresponding to the data that has been changed, i.e., the unchanged parts of the file are not changed. Therefore, it is possible to update data with remarkably little communication amount. The information management section of the addressee displays the changed part in a manner so as to be discriminated from other unchanged part. Accordingly, the user can identify the changed part.
