The present invention relates to a two-way pager, and more particularly, to a method for storing and managing after setting and transmitting a response message in association with received data.

Typically, a one-way pager stores a message received at its own address to alert and display the received message. At this time, the received message is stored in the internal memory so that the user can check it if necessary. On the other hand, the interactive pager has a function of transmitting an acknowledgment message (hereinafter referred to as an ACK) message to a received message or by selecting a random data by the user.

That is, the user reads received data about a message received at his or her address using a two-way pager, and the user selects and transmits an ACK message for data having an ACK request. Here, it is sometimes difficult for a user to remember one ACK message sent for a plurality of ACK messages. In addition, when the transmission of the ACK message fails, the cumbersome work of selecting and transmitting the selected ACK message again when selecting and sending data again occurs.

Accordingly, an object of the present invention is to provide a method for transmitting / receiving an interactive pager for a response message for storing an ACK message for transmission of received data and corresponding information in a transmission / reception management table in association with received data.

Another object of the present invention is to provide a method of transmitting / receiving a two-way pager for a response message managing an ACK message to be retransmitted by one key operation when data fails to be transmitted.

In order to achieve the above object of the present invention, a method of transmitting and receiving a two-way pager having at least one response message and a transmission / reception management table, wherein the received message requesting the response message is set in a selection mode to receive the response message. Selecting one message and transmitting the response message, the response message selected in the selection mode, the transmission status of the response message, the transmission time and date of the response message, and the received data Storing in the corresponding area of the transmission / reception management table, the response message stored in the transmission / reception management table in response to a user's request, the transmission status of the response message, the transmission time and date of the response message, and the received data. It is characterized by consisting of the process of displaying in conjunction with .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that like elements in the figures represent like reference numerals wherever possible.

As used herein, the term “transmission / reception management table” refers to storing received data and an ACK message transmitted in association with the received data and corresponding information in the corresponding area. The term acknowledgment message (ACK message) indicates that it is preset and set to at least one message.

1 is a configuration diagram of a bidirectional pager for carrying out the present invention. The RF receiver 112 receives radio call information applied through an antenna 111 to perform functions of frequency conversion, demodulation, and waveform shaping. Therefore, the output of the RF receiver 112 becomes radio call information converted into digital data. The output of the RF receiver 112 is applied to the decoder 113. The decoder 113 decodes and outputs a power control unit for controlling the power of the bidirectional pager and received digital coded data. The decoder 113 decodes the received encoded data (generally BCH encoded data) into original data. In the idle mode, the supply of the operating power is controlled at regular intervals to detect the preamble data, and in the batch mode, the word sync data and the set frame data are detected.

EEPROM 116 stores the information of the interactive pager and the ACK message, and stores the operation program of the interactive pager and the program of the present invention. RAM 115 temporarily stores data generated during program execution. According to the present invention, the RAM 115 includes a transmission and reception management table to store information related to received data and an ACK message. The key array 118 includes a read / read mode key for setting a mode, a read / receive read mode key, a select mode key, and a key for performing various operations. The liquid crystal display 117 displays received data, transmitted / received data, etc. in accordance with an applied display control signal. The alarm unit 121 generates an alarm signal such as a tone signal or a vibration signal for notifying that the alarm signal has been called by an applied alarm control signal.

The microprocessor 114 receives the decoded data output from the decoder 113 and processes the received data to control an alarm function. In addition, the microprocessor 114 generates an alarm signal to control the alarm unit 121, a mode is set according to various keys applied by the key array 118, and controls the liquid crystal display 117 to display received data and transmitted / received data. . The microprocessor 114 stores the ACK message selected by the reception data requesting the ACK and related information thereof in the corresponding area of the transmission / reception management table of the RAM 115 in association with the reception data.

The RF transmitter 119 modulates and amplifies and transmits the transmission message to the transmission antenna 120 under the control of the microprocessor 114. Accordingly, the transmission antenna 120 transmits an applied transmission message.

2 is provided in EEPROM 116 as a memory map diagram for an ACK message. Hereinafter, referring to FIG. 2, the EEPROM 116 stores preset messages in order to select an ACK message for the data received by the user in the interactive pager. This is preset at the time of manufacture. Accordingly, in the present invention, the ACK message is set as expected to arrive in 10 minutes after receiving the message, which is now going.

3 is a flowchart of a method of transmitting and receiving a bidirectional pager for a response message according to a preferred embodiment of the present invention. 4 is a memory map diagram of a transmission / reception management table storing information of response messages in association with received data according to an embodiment of the present invention. Hereinafter, a description will be given with reference to FIGS. 1, 2, 3, and 4.

When the reception data is applied from the decoder 113, the microprocessor 114 outputs an alarm control signal to the alarm 121. Then, the alarm unit 121 generates an alarm signal to inform the user that the call has arrived. Thus, when the read mode key is applied in step 311, the microprocessor 114 checks whether the key is for the receive read mode or the transmit / receive read mode. In operation 312, when analyzed as being in the read read mode, the microprocessor 114 is set to the receive read mode. Accordingly, the liquid crystal display 117 displays the received data under the control of the microprocessor 114. At this time, the user can confirm whether the received data is a message requesting an ACK. That is, Table 1 below shows a displayed embodiment of received data requesting an ACK message to the liquid crystal display 117. Table 2 below shows a displayed embodiment of received data that does not require an ACK message to the liquid crystal display 117.

Accordingly, when the table 1 appears in the liquid crystal display 117, the user touches the selection mode key for setting the selection mode in the key array 118. In addition, when the table 2 is displayed on the liquid crystal display 117, the user touches the read mode release key to release the read mode set from the key array 118. Thus, when the selection mode key is not applied in step 314 and the read mode release key is applied, the microprocessor 114 releases the read mode and ends. On the other hand, when the selection mode key is applied in step 314, the microprocessor 114 is set to the selection mode to select an appropriate ACK message from a plurality of ACK messages stored in the EEPROM 116.

In this case, the process for selecting the ACK message will be described. When the selection mode key is input, the microprocessor 114 causes the message reception message of the first area of FIG. 2 to be displayed. Here, when the selection setting key is applied by the user, the microprocessor 114 selects and sends a message as an ACK message to be sent, and when the reselection marking is applied, the message in the second area of FIG. Displayed on the display device 114. As such, the user may select the ACK message displayed on the liquid crystal display 117. On the other hand, according to another method, when the selection mode key is input, the microprocessor 114 displays all the ACK messages on the liquid crystal display 117. Accordingly, the selection display displays the message of the first area to the message of the M area in FIG. 2 based on the selection decision key. In this case, the selection display may be set to a bar or the like. Thus, when the selection decision key is inputted in the specific ACK message indicated by selection, the ACK message is selected.

When the ACK message is selected by the above process, the microprocessor 114 releases the ACK message selection mode in step 317. Thereafter, when the transmission request key is applied by the user in step 318, step 418 transitions to step 319. In operation 319, the microprocessor 114 outputs the selected ACK message to the RF transmitter 119. The RF transmitter 119 then transmits the ACK message through the transmit antenna 120. In operation 320, the microprocessor 114 releases the ACK transmission mode. In operation 321, the microprocessor 114 stores the authorized received data, the ACK message, and information related to the ACK message in a transmission / reception management table of FIG. 4.

Referring to FIG. 4, when the transmission / reception management table transmits the received data # 1 storing the received data, the ACK status information # 1 indicating whether the ACK is requested, and the ACK message in association with the received data, the ACK message is transmitted. ACK message # 1 for storing the ACK message, ACK time # 1 for storing the information, such as the time, date, and the like for transmitting the ACK message corresponds to the first region, and the second-second N region is provided. Accordingly, the transmission / reception management table stores reception data and ACK related message from the first area. If all the messages are stored in the first to Nth areas, the microprocessor 114 deletes the messages in the first stored area and stores the messages in the area.

In operation 322, the microprocessor 114 displays transmission / reception data on the liquid crystal display 117. Examples of the transmission / reception data of the liquid crystal display 117 at this time are shown in Table 3 below.

Transmitting and receiving data as shown in Table 3 is displayed when transmitted through the transmitting antenna 120.

On the other hand, if the transmission / reception data displayed on the liquid crystal display 117 is shown in Table 4 below, the transmission is failed.

As shown in Table 4, a failure message that fails to be transmitted is generated when the transmission is not synchronized with the base station, that is, when the transmission pager state fails to transmit, or when the RF transmitter 119 fails to transmit power. Thus, in step 323, when the user recognizes that the transmission has failed and touches the retransmission request key to request retransmission, step 323 transitions to step 324. In operation 324, the microprocessor 114 outputs an ACK message to the RF transmitter 119. Thus retransmission occurs. Meanwhile, when the transmission / reception data shown in Table 3 is displayed and the retransmission request key is not input in step 323, the microprocessor 114 checks in step 325 whether the read mode release key is input. When the user recognizes that the transmission is completed and touches the read mode release key, the read mode release key is input in step 325, so the microprocessor 114 releases the read mode in step 332.

In operation 311, when the read mode key is in the transmit / receive read mode, the microprocessor 114 performs the process of step 327 in step 326. In operation 327 and operation 328, the microprocessor 114 displays the received data of the first region of FIG. 4 and information related to the ACK message and the ACK message on the liquid crystal display 117. Examples of the displayed data are shown in Table 5 below.

As shown in Table 5, data stored in the first area is displayed. The microprocessor 114 then checks if a re-display key is input by the user in step 329. When the re-display key is input, data stored in the second area of the transmission / reception management table is displayed on the liquid crystal display 117 by steps 329 and 328. By the above process, the user can determine what kind of ACK message is transmitted according to the received data.

When the read display key is not input in step 329 and the read mode release key is input in step 329, the microprocessor 114 releases the read mode in step 332.

As described above, the microprocessor 114 of the present invention includes a transmission / reception management table to store an ACK message in association with the reception data to display the reception data. It can be easily confirmed, and if the transmission fails, there is an advantage that can be retransmitted by the key operation by the retransmission request key.
