In order to achieve the above object, the present invention provides a data transmission method applied to a high-speed wireless paging system, wherein a subscriber selects a data transmission service using a voice mailbox, and transfers the call processing from the voice mailbox to a file transfer server. Stage 1; The file transfer server loads the service item and transmits the service item to the high speed radio calling system, and the high speed radio calling system transmits the data to be transmitted to the hex / binary vector and hex of the FLEX protocol. After dividing into HEX / Binary Message, use Hex / Binary Vector and Hex / Binary Message of FLEX protocol. Transmitting to a wireless calling terminal; And receiving a corresponding data transmission message, receiving the corresponding data, connecting the divided data, and processing the data according to a corresponding service.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

1 is a block diagram of a wireless call system to which the present invention is applied.

The subscriber connects to the wireless call exchanger 2 through the public telephone network 1, and the wireless call exchanger 2 processes the station number classification, subscriber management, the type of subscriber service, and transmits it to the wireless call terminal 4. In this case, when the voice mailbox 3 is to be used, the voice mailbox 3 additionally installed in the wireless call exchanger 2 may be used.

Thereafter, the wireless calling terminal 4 transmits a signal encoded according to the wireless calling signal to the wireless calling base station 5, and the wireless calling base station 5 wirelessly transmits to the wireless calling terminal 6 using airwaves. Send the call signal. In this case, the high-speed wireless call signal used may be a flex (FLEXible) protocol, etc. In the present invention, a method of transmitting data using the flex (FLEXible) protocol will be described as an example.

2 is an explanatory diagram for a signal processing procedure in a high speed radio calling system to which the present invention is applied.

First, in order for a fast radio call subscriber to receive a file stored in the radio call file transfer server 8 to the radio call terminal 6, the subscriber input device 7 of the high speed radio call system using the public communication network 1. ), And enter the radio calling number, the central processing unit (9) of the high-speed radio calling system searches the subscriber management database (DB) using the entered radio calling number and is a valid subscriber, a subscription area, and a broad subscriber. After searching for the current moving area and the type of service subscribed to, the subscriber can select the file transfer menu using the voice message of the voice mailbox 3 in the case of a valid subscriber.

If the subscriber selects the corresponding number for data transmission, the central processing unit 9 of the high speed radio calling system processes the call to the file transfer server 8, and the file transfer server 8 processes the high speed radio calling system. Data is transmitted to the wireless calling terminal 6 through the central processing unit 9, the wireless calling terminal 4 and the wireless calling base station 5. When the subscriber's file transfer is completed, the voice mail box 3 sends the completion message to the subscriber.

On the other hand, when transmitting data from the paging system to the paging terminal, the plex (FLEX) method uses a hexadecimal / binary message (HEX / Binary Message).

That is, the flex protocol uses a hex / binary vector as the data transmission message and a hex / binary message as shown in Table 1 below.

In the hexadecimal / binary message, actual information starts from the third codeword as shown in [Table 1], and the first and second codewords are control information. The definition of the control information is defined in "FLEX G1.8", which will be briefly described in the present invention.

k0 k1 k2 k3 k4 k5 k6 k7 k8 k9 k10 k11: Fragment Checksum

c0: Message Continued Flag

F0 F1: Message Fragment Number

N0 N1 N2 N3 N4 N5: Message number

R0: Message Retrival Flag

D0: Display Direction Field

H0: Head Message

B0 B1 B2 B3: Block Length

s0 s1 s2 s3: Reserved

I0: Status Information Field Enabler

S0 S1 S2 S3 S4 S5 S6 S7: Signature Field

The actual data message is transmitted by a0 a1 a2 a3 b0 b1 b2 b3 c0 c1 c2 c3 d0 d1 d2 d3 d4 ... etc., and is composed of 4 bit units. As described above, since the first and second codewords of the hexadecimal / binary message are used for transmission of control information, they actually act as an overhead.

Therefore, in the present invention, the third codeword is transmitted for data transmission, and the format of the data transmission message is defined as shown in Table 2 below.

data Version Full data Appetizer packet Currently sent real Kinds Length Count Packet number data (4 bits) (4 bits) (8 bits) (8 bits) (8 bits) (n bit)

Looking at the contents of Table 2 in detail, it is shown in Table 3.

Justice Length (bits) Contents Etc Data type 4 Depends on service type Version 4 The version of the particular service Full data 16 Total data length bytes Total packets Length Starting from Total packets 8 Total Packets Transmitted Current packet count 8 Packet number currently sent Actual data n Actual data content In bytes

The data transmission method according to the present invention is a method of dividing and transmitting data in order to transmit relatively long data in radio call data. For example, in order to transmit game software (S / W) to a radio call terminal, the following is performed. Just do it.

1) Data Type: 1100 (Game Software)

2) Version: 0011 (the third version of the game defined earlier)

3) Total data: Total data length: 00000000 00001000 (8 bytes)

4) Length Total Packets: Total Packets

5) Current number of packets: Number of currently transmitted packets

In the above example, the total data length starts after the message and is calculated in bytes.

3 is a flowchart illustrating a data transmission method in a high-speed wireless paging system according to the present invention.

When the subscriber wants the data transmission service, the subscriber should access the high-speed wireless paging system by using the voice mailbox 3. When the subscriber enters the corresponding radio calling number (31), the high-speed radio calling system checks whether the subscriber is a valid subscriber (32), and terminates immediately if it is not a valid subscriber. 33) It is determined whether the service selected by the subscriber is a data transmission message (34). If the data transmission service is not a data transmission service, the service is immediately terminated (35). If the data transmission service, the voice service of the voice mailbox 3 is used. When the desired service selection is completed (36), the call processing is transferred from the voice mailbox 3 to the file transfer server 8 (37).

Thereafter, the file transfer server 8 loads the corresponding service item and transmits the service item to the high speed radio calling system. It transmits to the wireless call terminal (38).

4 is a flowchart illustrating a data receiving method in a wireless call terminal according to the present invention.

In the normal standby state 41, the radio calling terminal 6 receives a hexadecimal binary code (HEX / Binary Vector) with a specific CAP code (specific address stored in the radio calling terminal), that is, a data transmission message. When receiving (42) compares the service type stored in the corresponding wireless calling terminal and the received service type during the data transmission service and checks whether it matches (43).

If the two service types do not match, the mobile station transitions to the normal standby state 41 of the wireless calling terminal, and if the two service types match, after receiving all the corresponding data transmission messages (44), the data is connected to suit the service. Process and end (45).

On the other hand, for example, when the game machine and the radio call terminal are combined, the composite terminal receives the message and then displays the reception completion message on the composite terminal and returns to a normal state.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

As described above, the present invention can further extend the current wireless calling service to transmit various data, and in particular, a large amount (more than 5KBytes) of data can be transmitted, thereby downloading files and game software (S / W download), It is effective to create various application services such as e-mail and internet information transmission, remote meter reading information transmission, and various life information transmission of data inclination.
