How to manage protection message of pager

The present invention relates to a wireless pager, and more particularly, to protect a received message that a user considers important while using a wireless pager. In this case, the present invention relates to a protection message management method of a wireless pager that reads or deletes only protected messages.

A PAGING RECEIVER is a device that displays a message received by subscribing to a paging service provider.As a user of such a pager, the user receives a message received for the purpose of protecting a received message that is deemed important or a message he / she wants to remember. Message protection (generally called the message lock function). Conventionally, a method for protecting such a message is to notify a user by displaying a protection mark on a corresponding message when displaying a protection message to inform the setting of a message protection function.

However, in the case of the protection message display provided by the conventional pager, only the protection message is displayed to distinguish the general received message from the protection message when the protection message is displayed.

In order to solve this problem, a method of easily managing a protected message includes a separate memory area, and stores only the protected message separately, and reads and displays a separate memory area in which the protected message is stored when the user selects it. However, such a separate memory management for the protection message has a problem that must have a separate memory for storing the protection message.

Accordingly, an object of the present invention is to provide a protection message management method of a wireless pager for managing a protected message without having a separate memory in order to solve the above problems.

In order to achieve the above object, the present invention provides a method of managing a protection message of a wireless pager including a message table, a message table pointer, a protection message table, and a protection message table pointer, wherein the message stored in the message table is searched and searched. Checking whether a message is a protection message, and storing a corresponding message number in the protection message table if the protection message exists.

1 is a block diagram of a wireless pager according to the present invention.

2 to 5 are memory configuration diagrams according to the present invention.

6 is a control flowchart for managing a protection message according to an embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention, such as specific processing flows. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. Detailed descriptions of well-known functions and configurations that are determined to unnecessarily obscure the subject matter of the present invention will be omitted.

1 shows a configuration of a wireless pager applied to the present invention. Referring to Figure 1 will be described the configuration and operation of the pager.

RECEIVER CIRCUITRY 11 receives radio call information and performs functions of frequency conversion, demodulation, and waveform shaping. Accordingly, the output of the receiver 11 becomes radio call information converted into digital data, and the output of the receiver 11 is applied to the decoder 13.

The decoder 13 sets the operation mode of the pager by decoding the received data. That is, 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. The detected frame data is decoded and converted into the original data form.

The MICRO CONTROLLER 15 processes the received data to control the alarm function and the vibration function, and reads the message table and stores a protection message table for storing the protection message when there is a protection message according to the present invention. And a protection message stored in the protection message table is read from the message table and displayed when the protection message is displayed by the user.

The memory 17 includes an area for storing letters and numbers generated during program execution, and an area for storing an INDIVIDUAL message and an MAILDROP message.

The display unit DISPLAY 19 displays the message of the calling party and the status information of the pager by the display control signal output from the controller 15, and displays the personal information corresponding to the telephone number received by the control of the controller 15. A display area is provided.

The alarm unit ALERT 21 generates an alarm signal such as a tone signal or a vibration signal for notifying that the alarm signal has been called by the alarm control signal output from the controller 15.

The key input unit 23 inputs a predetermined key when searching for a received message.

The memory configuration according to the present invention is as shown in Figs. 2 to 5, a memory diagram according to the present invention will be described;

2 is a configuration diagram of a message table for managing an area where personal call information is stored in a memory of a pager, wherein the message table is a table for managing an area where personal call information is stored, and a message table pointer is a new personal call information. Indicates the area to store when is received. In FIG. 2, a message table pointer of 7 means that 6 previously received messages are stored in the message table. Each time new private call information is received, the location of the storage area indicated by the message table pointer is increased by one.

The configuration of the message table is as shown in FIG. The message table is composed of 1 byte of STATUS information indicating the state of one private call information, 2 bytes of CHKSUM information indicating CHKSUM information of the message information received by the decoder 13, and 2 bytes of size indicating the length of the received message. MESSAGE LENGTH information of the information, information indicating the end region of the information stored in the external memory 17, 2 bytes of MSGEND information for determining how far to display and display when the user reads the message, and indicates the start block of the external memory 17. It consists of 1 byte of address information. The above two pieces of information (2 bytes of CHKSUM and 2 bytes of MESSAGE LENGTH) are used to determine whether a duplicate message is received the next time a new message is received.

4 is a one-byte STATUS configuration of the message table, where bit 7 indicates whether this information has been read by the user or unread, and bit 6 indicates whether this same information has been received before. , Bit 5 indicates whether the information is protected by the user for protection.

5 is a configuration diagram of a protection message table according to the present invention, in which a user stores only the messages of the protection state in the message table when the user wants to separately read the messages of the protection state. If messages 3, 4, and 5 of the messages stored in the message table are in the protected state as shown in FIG. 5, the message is stored, and the protection message table pointer indicates a location area to be stored next. In the present invention, a protection message is applied only to a personal memory area, that is, a personal call information message stored in a message table, but not to an information service memory. This does not apply because the information service message is always updated with a new message, but it will be apparent to those skilled in the art that the information service message may be sufficiently implemented by the technology applied to the present invention. .

6 illustrates a preferred method of managing the protection message table. A preferred embodiment of the present invention will be described with reference to FIGS. 1 to 5 described above. 6 is a control flowchart for managing a protection message according to an embodiment of the present invention.

In step 101, the controller 15 controls the message table search number (called i) and protection message table number (called j) according to the protection message table management according to the present invention (i = 0, j = 0). Checks if the message table pointer is larger than the set message table search number i. If the message table pointer is larger than the message table search number i, the process proceeds to step 103 and ends if the message table pointer is smaller. In step 103, the controller 15 checks whether bit 5 (Lock or Unlock information value) of the STATUS of the i-th message table has a value of "1". Meaning that the value of bit 5 is “1” means that the message is a protection message. If the value of bit 5 is "0", the message is not a protection message, and therefore, the flow proceeds to step 105 to search for the next message. If bit 5 (Lock or Unlock information value) of the STATUS of the i-th message table has a value of "1", go to step 104 and store the protection message table number, i.e., the corresponding storage position of the protection message table, as i value. The protection message table number is increased by one. This increases the value of the protection message table pointer by 1 to indicate the protection message table position to be stored next. Thereafter, in step 105, i = i + 1 is set to increase the search number of the message table to be searched by one, and then the process returns to step 102 and the above process is repeated sequentially. In this way, when there is a new protection message, the controller 15 may continuously store it in the protection message table.

If the user selects the protection message search function according to the present invention, the controller 15 reads the protection message stored in the protection message table from the corresponding storage area of the message table and displays it. Each time the user presses the search key, the controller 15 reads and displays only the protection message from the message table. Even when the protection message is deleted, if the user selects to release the protection message when the protection message search function is performed, the protection message is deleted from the protection message table.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention provides a protection message retrieval function without providing a memory when the user adds a function of displaying only the protection message when there is a protection message that is determined to be important or to be protected. can do.
