It provides only a simple backup function of the received data, there is a problem that causes the loss and error of data transmitted due to a bad connection of the connector when transmitting the data information received through the connection of the connector.

Accordingly, an object of the present invention is to add a high speed wireless call modem and an infrared communication function to a portable information terminal so as to reliably receive and store data information transmitted from a wireless call network at high speed, and store the received stored data information in a host or other manner. In the transmission to the device, the data synchronization between the portable information terminal and the PC or an external device is achieved so that post processing of the received data and previously received data is implemented.

In this case, the ROM 505 and the RAM 506 are flash memories, and a buzzer 608 for instructing a user of a device is used as a vibration generator or an LED.

6 is a configuration diagram of a wired / wireless data communication network according to the present invention, in which a power source of a battery stored in a battery case is processed in a predetermined state by the DC / DC converter 507, and thus an operating power source 3.3 required for the main processor 501. According to the access request signal of the data information required by the portable information terminal 601 in a standby mode for processing information of the portable terminal supplied with power for driving the V and the display unit 502, a database for various information is provided. As shown in FIG. 8, the data requested for access from the caller server 609 connected to the Internet 604 through a base station 608 and a dedicated line or aerial line 607 for wireless communication is established. After compression to 128 frames, the transmitter 610 transmits a wireless airwave at a set transmission rate, for example, 6400bps.

At this time, the wireless call data receiving unit 509 of the portable information terminal receives the wireless call data received through the antenna ANT, processes it in a predetermined state, and applies it to the main processor 501.

The main processor 501 is set in the RAM 506 to analyze the received data information through an analysis program, and displays the analyzed information to the user through the display unit 502.

As described above, the data information analyzed through comparison with the analysis program set in the RAM 506 is temporarily stored in the address address of the RAM 506 designated by the main processor 501, and the stored data information is previously stored. Database with received and stored data information.

In addition, a selection signal for information processing of the portable information terminal is detected from the key input unit 511 including a predetermined key button and a selection button on the main processor 501 or touched through the A / D converter 504. When a signal for selecting the information processing of the panel 503 is detected on the main processor 501 side, the main processor 501 is requested by the user through an operation analysis program set in the ROM 505 or the RAM 506. In addition, the display unit 502 displays an operation state which is processed at the same time as the analysis data is processed, and designates and stores the address area of the RAM 506 for the data on which the information processing is completed.

If the signal for requesting information processing input through the key input unit 511 or the touch panel 503 is a signal for requesting transmission to a host or other device through infrared communication, the main processor 501 transmits an infrared signal according to the required signal. The control unit 510 maintains the standby state for data transmission, and then instructs the display unit 502 to request a data designation for transmission.

At this time, when the corresponding data is designated from the key input unit 511 or the touch panel 503 according to the supported message, the main processor 501 reads the corresponding data stored in the RAM 506 or the ROM 505. Synchronize the data with the host or device for the next transmission and then send that data as an infrared signal.

Next, the operation of the portable information terminal will be described. As shown in FIG. 7, in the state where the portable communication terminal is waiting for operation, the main processor 501 uses the key input unit 511 or the D / A converter 504. It is determined whether an event requesting data processing from the touch panel 503 is processing of data information received through a wireless call, whether the event requires post processing or a data synchronization request for infrared communication, and the main The processor 501 accesses an operation program for processing data required from the ROM 505 and the RAM 506 and executes the operation (step 701).

Therefore, if the event request for processing the data information received through the high-speed wireless call (step 702), the main processor 501 receives the data received through the operating program accessed from the ROM 505 and RAM 506. After analyzing (Tag) (step 705), necessary data such as a user ID and a reception time of the analyzed data information are added (step 708), and the data is stored in the RAM 506 designated by the main processor 501. According to (Tag), the data is stored at the address address (step 711), and the database is made (step 712).

However, if the event generated in step 701 is a signal for requesting post-processing of the received data (step 703), the main processor 501 responds according to the operating program accessed from the ROM 505 and the RAM 506. After the data of the application program is post-processed (step 706), the processed state is displayed to the user through the display unit 502 (step 709), and the post-processed data is made into a database (step 712).

On the other hand, if the event generated in step 701 is a signal for requesting data transmission to a host or other device connected through a serial communication port or infrared communication, the main processor 501 is required for data synchronization from the ROM 505. After accessing the operating program (step 704), the host or the device is connected via the infrared communication unit 510, and then the synchronization of the designated data for transmission is performed (step 707). 506), and make a database (step 712).

As shown in FIG. 8, the data information received through the high-speed wireless call is formed in a compressed form of 128 frames. Each frame includes header information consisting of "sync 1, frame info, sync 2" and 11 pieces of information. It is composed of blocks, and 11 blocks are composed of "BIW (block information word), address, vector, message, idle".

Since the "message" consists of "tag, date", the main processor 501 realizes "tag, date" from the "message" in order to synchronize in the process of transmitting the received data.

Since the "tag" is registered as an IP by the radio calling service provider, the "tag" is to provide reliability for data communication.

Therefore, since the tag is analyzed from the main processor 501 and the address address is designated, the RAM 506 stores the received data information 802 and makes a database of the received data. Synchronization is realized.
