Abstract

PURPOSE:To enable to many messages to be written by writing once a message in receiving a message with an error and overwriting a next message without error in receiving the next message onto the preceding message so as to erase the message with error in a memory thereby attaining the effective use of the memory. CONSTITUTION:In receiving a message S1 without error, the message S1 without error is written in the uppermost part of the memory 1. In receiving a message S2 with error, the message is written once next to the message S1 without error in the memory 1. In receiving a message S3 without error, the message S3 without error is overwritten onto the written area of the message S2 with error to erase the message S2. Then messages S4, S5... without error are written sequentially to attain the effective use of the memory 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a message storage method in a selective call reception system with a display that displays messages sent from a base station on a display unit after receiving and decoding them.

[Prior Art] In the conventional selective call receiving system with display, no error message 81. Message with error 82. No error message 83. When S4.85°86.87 are received in sequence, these messages 81 to S7 are written to the memory 1 in the order in which they were received, as shown in FIG. 2, until the free area 1A of the memory 1 is exhausted. The newest message is overwritten on top of the oldest message (in this case, message S1), and the old message (in this case, message S1) is overwritten.
In this case, the message 81) was erased and the latest message was written there.

[Problems to be solved by the invention] However, with this method of storing messages,
Since the message S2, which is useless and contains an error, is also stored, there is a problem that the memory area of the memory 1 cannot be used effectively.

SUMMARY OF THE INVENTION An object of the present invention is to provide a message storage method in a selective call receiving system with a display that allows effective use of memory area.

[Means for Solving the Problems] The means of the present invention for achieving the above object will be explained with reference to FIGS. 1(A) and 1(B) corresponding to the embodiment. ．． S2. Every time S3... is received, it is written to memory 1, and the free area 1A of said memory 1 is
In a message storage method in a selective call receiving system with a display that updates the message by overwriting the latest message on top of the oldest message S1 when the message S1 is no longer available, when an error message S2 is received. temporarily stores the error message S2 in the memory 1, and when the next message S3 is received, the legal message S3 is written on top of the error message S2.
The error message S2 is erased by pressing repeatedly.

[Operation] By doing this, the message S2 with an error is erased by overwriting the message S3 with no error on top of the message S2 with an error when the next message S3 without an error is received, so that the memory area can be used effectively. I can figure it out.

[Examples] Examples of the present invention will be described below with reference to FIG. 1(Δ)(B). Note that parts corresponding to those in FIG. 2 described above are designated by the same reference numerals. In this embodiment, when an error-free message S1 is received, the error-free message S1 is written at the top of the memory 1 (at the writing start end) as shown in FIG. 1(A). Next, when a message S2 with an error is received, the message S2 with an error is temporarily written next to the message S1 without an error in the memory 1, as shown in FIG. 1(A). Next, when the error-free message S3 is received, as shown in FIG.
Erase message S2 with error. Next, when the error-free messages S4, 85, 86, and 87 are received in sequence, these error-free messages S4 to S7 are sequentially written in the memory 1 next to the writing location of the error-free message S3.

When there is no more free area 1A in the memory 1, the newest message is superimposed on the oldest message (message 81 in this case) and the oldest message $1 is erased.

In addition, each message 81.83. When writing ~S7... to memory 1, it is determined whether it is the same as the message that has already been written, and if it is the same, the message is rearranged to the position of the newest message, and if it is a different message, it is determined as described above. It works on top of the newest message.

[Effects of the Invention] As explained above, in the present invention, when a message with an error is received, the message with an error is written to the -H memory, and when a message with no error is received next, the message with an error is written. Since the error-free message is overlaid on top of the error message and the error-containing message is erased, the memory can be used effectively and more error-free messages can be written.

[Brief explanation of drawings]

Claims (1)

[Claims] A message storage method in a selective call reception system with display, in which each message is written into a memory every time a message is received, and when the memory is full, the latest message is overwritten on top of the oldest message to update the message. When a message with an error is received, the message with an error is temporarily written into the memory, and when the next message is received, the next message is overwritten on the message with an error, and the error message is written. A message storage method in a selective call reception system with a display, characterized by erasing existing messages.
