Abstract

In the handheld terminal device, when a message reception unit receives from a host computer a new arrival message indicating a new arrival of a file (or electronic mail), a control unit analyzes the new arrival message to obtain identifier information for identifying the file (or electronic mail) and a telephone number of the host computer. After a line connection to the host computer is established by a handheld phone transceiver unit, a fetch request command for fetching the file (or electronic mail) is transmitted to automatically fetch the file (or electronic mail) from the host computer and make the user know the contents of the file (or electronic mail) by using a display unit. A FAX transmitting user designates a destination handheld terminal device and transmits FAX image data to a communication server (CS). CS stores the received FAX image data and transmits a FAX arrival message to a pager connected to the destination handheld terminal device. A user of the handheld terminal device informed of a FAX arrival by the pager confirms the FAX brief image data contained in the message, and if necessary, calls CS by a handheld phone connected to the handheld terminal device to make CS transmit the FAX image data and refer to the detailed contents thereof.

Claims24

Dependent claims

A data transfer system having a host computer for receiving data, storing the received data, and transmitting the stored data, and at least one handheld terminal device with a communication function for receiving data transmitted from said host computer, wherein:

said host computer comprises:
a storage unit for storing the received data;
a transmission control unit for performing a transmission control for transmitting a new data arrival notice command to said at least one associated handheld terminal device, said new data arrival notice command including a command name and a command parameter, said command parameter including data identifier information for a data file identifier for identifying the received data on a file basis and connection information necessary for said at least one handheld terminal device to access said host computer but not including the received data itself, and
a host side transmission/reception control unit for performing reception processing of a transmission request command transmitted from said at least one associated handheld terminal device, said transmission request command including a command name and a command parameter for identifying the received data and transmission processing of the received data identified by said transmission request command to said at least one associated handheld terminal device;
and
said at least one associated handheld terminal device comprises:
a new message arrival analysis processing unit for analyzing said received new data arrival notice command and deriving said data identifier information and said connection information,
a connection establishment processing unit for performing connection processing of a communication line to said host computer in accordance with said connection information, and
a terminal side transmission/reception control unit for controlling transmission processing of transmitting said transmission request command in accordance with said data identifier information and reception processing of receiving the received data transmitted from said host computer.

6 more elements

A data transfer system, comprising:

at least one handheld terminal device for generating, storing, and displaying data to be transmitted and received, said handheld terminal device having connection means for connecting to a public telephone line and data transmission control means for performing transmission/reception of data transmitted and received via said public telephone line;
and
a communication server having connection means for connecting to said public telephone line, data transmission control means for performing transmission/reception of the transmitted and received data via said public telephone line, and a storage unit for storing received transmission data,
wherein said communication server sends a notice command including a command name and a command parameter, via said public telephone line, said command parameter including a data file identifier for identifying for the received transmission data on a file basis and connection information necessary for said handheld terminal device to access said communication server after analysis of said notice command but not including the received transmission data, to said handheld terminal device designated by said received transmission data, and, in response to a transmission data transfer request command transmitted from said handheld terminal device, said transmission data transfer request command including a command name and a command parameter including said data file identifier obtained by analyzing said notice command, transmits the received transmission data to said handheld terminal device.

1 more element

A handheld terminal device with a communication function, comprising:

new data arrival message reception controlling means for receiving a newly arrived data notice message indicating reception of new data;
and
transmission/reception controlling means for controlling data acquisition processing in accordance with the contents of said newly arrived data arrival notice command, wherein said newly arrived data notice command includes a command name and a command parameter, said command parameter including data identifier information for identifying said data and connection information necessary for said handheld terminal device to access a host which stores said new data but does not include of body of said new data, said reception controlling means has a newly arrived data notice command analysis processing unit for analyzing said received newly arrived data notice command and deriving said data identifier information and said connection information, and said transmission/reception controlling means has a connection establishment processing unit for performing a connection processing of a communication line in accordance with said connection information and received data transmission controlling means for controlling a transmission processing of said data in accordance with said data identifier information.
