Abstract

PURPOSE: A method for preserving a not-read information message in a paging receiver is provided to configure a memory into an individual memory area, an information memory area, and an information preserving memory area. CONSTITUTION: If a new information message is received in a paging receiver, a controller retrieves a storage location of an information memory. The controller checks whether an information message is previously stored in the storage location. If the prestored information message is a not-read information message, the controller moves the not-read information message to an information preserving memory, and stores the not-read information message in the information preserving memory. The controller stores the new information message in the storage location of the information memory.

Description

How to protect unread information message from pager

The present invention relates to a method of storing an information message received by a pager, when a new information message is received in an information message storage area in which an unread information message is received, without discarding or storing the previously unread information message in a personal memory. It is about a method for protection.

A wireless caller (SELECTIVE CALL RECEIVER or PAGING RECEIVER) is a device that displays a message received by subscribing to a wireless call service provider, and a general configuration of such a pager is shown in FIG. 1. A configuration and operation of a general pager will be described with reference to FIG. 1.

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 controller 15 processes the received data to control an alarm function and a vibration function.

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.

When the INDIVIDUAL message or the MAILDROP message is received in the pager configured as described above, an area to be stored in the memory is determined based on the received address, which is stored when the message is received in the conventional pager. The configuration of the memory is shown in FIG. The memory 100 is divided into a personal memory 110 and an information memory 120 and stored in the personal memory 110 when a personal message is received and stored in the information memory 120 when an information message is received.

Meanwhile, if an information message having the same address is already stored in a corresponding storage area when an information message is received in the wireless pager, a method of processing a newly received new information message is needed, and if the information message already stored is not read. In the case of messages, more efficient processing will be required.

In the prior art, US Patent No. 5,379,031 entitled "METHOD AND APPARATUS FOR CONVERSION OF MAILDROP MESSAGE TO SELECTIVE CALL INDIVIDUAL", which was previously filed by Motorola, Inc., for the processing of an information message already received and stored when a new information message is received in a pager. MESSAGE ". The method for processing a new information message disclosed in US Patent No. 5,379,031, filed by Motorola, Inc., is an unread information message in a corresponding information message area when a new information message is received in a pager having a memory structure as shown in FIG. Is already received and stored, in order to protect the unread information message, previously received unread information message is moved from the information memory 120 area to the personal memory area 110, and the new information message is moved to the information memory 120 area. The way to save it.

However, storing the previously unread information message having the same address in the personal memory area when receiving a new information message as described above causes a problem that the user's personal message storage capacity is significantly reduced. Due to the lack of personal messages that can be stored could not be stored, but the problem is that even if you delete the unread information messages, the efficiency of information utilization is also reduced.

Accordingly, an object of the present invention is to effectively solve a previous unread information message when a new new information message is received with an unread information message in a method of storing an information message received at a pager to solve the above problem. The present invention provides a method of protecting an information message that is not read by the protecting pager.

In order to achieve the above object, the present invention provides a method for protecting an unread information message in a pager, wherein the memory comprises a personal memory area, an information memory area, and an information protection memory area, wherein a new new information message is received in the pager. When the information message is already stored in the location to be stored in the information memory, and when the previously stored information message is an unread information message, the unread information message in the information memory is transferred to the information protection memory. And storing the new information message in a corresponding storage location of the information memory where the unread information message is located.

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.

The configuration of the pager according to the present invention is the same as the configuration of the pager of FIG. 1 described above, and accordingly, it should be noted that the configuration and the reference numerals of the pager are the same. Meanwhile, the present invention has a memory configuration as shown in FIG. 3 in the configuration of the memory 17, and the present invention will be described based on the wireless pager memory configuration shown in FIG. In FIG. 3, the memory 200 separately configures the information protection memory 230 in addition to the personal memory 210 and the information memory 220. The personal memory 210 is a memory that stores the personal message when it is received. The information memory 220 is a memory for storing the received information message in the corresponding storage area according to the address of the received message when the information message is received. The information memory 220 is used in combination with the information table (shown in FIG. 4) in the description of the present invention. Be careful. In addition, the information protection memory 230 is an information message protection memory for storing an unread information message after moving it from the information memory 220 when an unread previous information message is stored in an area to be stored when the new information message is received. It should be noted that in the description of the present invention, it is used interchangeably with the information protection table (shown in FIG. 4).

An information memory 220 and an information protection memory 230 for storing and protecting the information message will be described in detail with reference to FIG. 4. FIG. 4 illustrates protection of an unread information message using an information protection table according to an embodiment of the present invention. Figure is shown.

In FIG. 4, the information table is a storage area table according to the storage of information messages configured in the information memory 220, and the information protection table is a storage area table configured in the information protection memory 230. When the pager receives the information message, the controller 15 first checks to which address the received information is received, calculates a corresponding area to be stored, and stores the information message in the corresponding area. If a new information message 'MD1N' is received at the address' a 'If the information message' MD1 'has not been read by the user in the corresponding storage area of the address' a', the previously stored information message ' Move MD1 'to the data protection table. In the process of moving, the address 'a' indicating that the received address is 'a' is moved together. The received new information message 'MD1N' is stored at the location of the information message 'MD1' which is moved to the information protection table. Then, the controller 15 increases the value of the information protection table by one information message from the information table to the information protection table. This is to prepare an area to be stored next in case a new unread information message is moved next time. When the new information message is received through the above process, if there is an unread information message in the corresponding area, the previous information message is moved to the information protection table and the new information message is stored in the information table.

In this way, if the user wants to read the information message through a key input, the unread information message is retrieved from the information table area to display the unread information message on the display preferentially, and is also stored in the information protection table. Unread informational messages that are present will be read and displayed on the display.

The above-described process will be described in detail with reference to the flowchart of FIG. 5. In the description, the configuration of the pager of FIG. 1 and the above-described FIGS. 3 and 4 will be described.

5 is a control flowchart for protecting an unread information message according to a preferred embodiment of the present invention.

If the message is received in step 301, the controller 15 checks whether the received message is an information message in step 303. If the received message is an information message, the process proceeds to step 307. Otherwise, if a personal message is received, the process proceeds to step 305 to perform a corresponding function according to the reception of the personal message.

In step 307, the controller 15 searches for a storage location for checking to which address of the information table 220 the received information message is received. In step 307, when the calculation of the location to be stored is completed, the controller 15 proceeds to step 309 and checks whether the previously received information message already exists at the location of the information table 220 where the received new information message is to be stored. If the previous information message exists in the corresponding storage location, the process proceeds to step 313. If the previous information message does not exist, the process proceeds to step 311. The controller 15 stores the received new information message in the corresponding information table area.

In step 313, the controller 15 checks whether the information message already existing in the area where the new information message is to be stored in the information table 220 has been read or not, and proceeds to step 315, and if not, proceeds to step 317. . If the previous information message is read, the controller 15 deletes the previous information message stored in the corresponding information table area in step 315 and stores the received new information message at the location. If the previous information message is an unread information message, the controller 15 calculates an area to be moved to the information protection table 230 in step 317. Here, the area to be moved is calculated by searching the remaining storage capacity that can be stored in the information protection table 230 after the area stored in the information protection table 230 and the storage capacity of the unread information message to be newly transferred from the information table 220. It is to calculate whether the remaining storage capacity of the protection table 230 is sufficient. After calculating the area to be moved, the controller 15 checks whether the remaining storage capacity of the information protection table 230 is sufficient to store the capacity of the information message to be newly transferred from the information table 220 in step 319. In other words, it is checked whether the memory of the information protection table 230 is in a full state. If the memory is in the full state, the process proceeds to step 327; The message is moved from the information table 220 to the information protection table 230 and stored. Thereafter, in step 323, the controller 15 changes the address to the address of the information message stored in the storage area of the information protection table 230. When the unread information message stored in the information table 220 is transferred to the information protection table 230 together with the address and stored, the control unit 15 stores the received new information message in the corresponding area of the information table 220.

On the other hand, if the memory of the information protection table is full in step 319, the process proceeds to step 327. In step 327, the controller 15 deletes the information message stored for the longest time of the information protection table and moves it to the new one in step 329. Move and save the informational message. That is, if the information protection table 230 sequentially stores information messages from the first part, the memory capacity corresponding to the capacity of the information message to be transferred from the information table 220 when the memory pool is generated is deleted after the first part. In operation 325, the controller 15 stores the received new information message in the corresponding area of the information table 220 as described above.

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, in the present invention, when there is an unread information message, when a new new information message is received, the present invention does not discard the previously received information message and preserves the unread message without reducing the memory usage of the personal information area. There is an advantage to storing the received information message.
