DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a selective call receiver will be described with reference to the drawings. FIG. 1 is a diagram showing a selective call receiver of the present invention. This selective call receiver includes an antenna 20, a receiver 21, and a controller 2.
2, a display unit 23, a buffer memory 24, a memory 25, a key button group 26, and an alarm unit 27.

The antenna 20 handles the radio signal from the called party via the relay station. The receiving unit 21 is the antenna 20.
Receives (receives) the wireless signal captured via the and decodes the received message. The control unit 22 is composed of, for example, a CPU (or a CPU and a main memory), takes in a received message from the receiving unit 21, manages the memories 24 and 25, takes in key operation contents from the key button group 26, and displays in the display group 23. It has at least each function of sending the display contents of, and sending an alarm signal to the alarm unit 27. Control unit 22
May decrypt the received message.

The buffer memory 24 is for temporary storage, and is preferably a FIFO buffer memory. The number of the addresses is n, and the memory has a format in which the first write (Fast in) content is read first (Fast out). Further, 1 received message is stored in the address. If the received message is stored in all addresses (1 to n) and cannot be written any more, the received message is shifted in the order of reception when the latest received message is received, and the oldest received message (first Received messages) are overflowed and discarded. Then, the latest received message is stored at the top address (the earliest address).

The memory 25 is selected by the user from the received messages in the buffer memory 24.
It is a memory that stores one or more received messages (received messages that should be kept). m (m <
It has an address of n) and stores one received message at one address.

The key button group 26 has at least a FIF.
A key (referred to as a first key) for instructing to read and update in accordance with the FIFO format from the O-type buffer memory 24 and a command for displaying the updated and read received message, and a reception message in the buffer memory 24 that should be selected and left. A key to be stored in the memory 25 as a message (referred to as a second key), a key for instructing change, correction, and deletion of each received message stored in the memory 25 (referred to as a third key), a key for instructing display and end (Called the fourth key).

Here, the modification, addition, and deletion of each received message in the memory 25 is an operation in which the user operates the received message that he wants to keep. The change means a change in the received message when there is a change in the waiting time after calling for confirmation of the received message, a correction when the sent message has an error, and the like. Addition refers to an example of adding detailed contents of a meeting place.

The operation of the receiver shown in FIG. 1 will be described. The receiving unit 21 determines whether or not the wireless signal from the called party captured by the antenna 20 is addressed to itself, and if it is addressed to itself, the reception message is received.

The control unit 22 temporarily stores the received messages in the FIFO type buffer memory 24 in the order of reception.
For example, it is assumed that the buffer memory 24 is all cleared (erased) and three reception messages M ₁ , M ₂ , and M ₃ are received in this order. When the control unit 22 receives the received message M ₁ , it stores it in the address 1. Next, when the received message M ₂ is received, the previously stored message M ₁ is shifted from address 1 to address 2, and the received message M ₂ is stored in address 1. When the reception message M ₃ is further received, M ₁ is shifted to address 3, M ₂ is shifted to address 2, and M ₃ is stored in address 1.

Further, when the control section 22 receives data in the order of M1.fwdarw.M2.fwdarw.M3 at the time of reading, which stores M ₃ at address 1, M ₂ at address ₂ , and M _{1 at} address 3, The reading is performed in the order of M ₁ → M ₂ → M _{3 and} the reading order is displayed on the display unit 23.

Further, when the received message to be retained is selected by a key operation from the outside, the control section 22 sends the selected received message from the buffer memory 24 to the memory 25 and stores it. When displaying the contents of the memory 25, the control unit 22 reads the contents and the display unit 23
Send to and display.

On the other hand, the operation will be described in relation to the key operation by the creator. The storage of the received message in the FIFO buffer memory 24 is performed by the control unit 22 based on its own judgment, regardless of the key operation by the creator. This buffer memory 2
Reading from 4 and its display are done by the sequence of the 1st key button.
When ON, the address is updated. When reading and displaying are terminated halfway, the first
Turn off the key button.

Selective storage of the received message to be retained from the buffer memory 24 is performed by the second key button. To this end, the stored contents of the buffer memory 24 are read out by the second key button (or the first key button) and displayed, and the second key button is turned on for each displayed received message, and the contents are retained. The desired received message is selected. The selected received message is stored in memory 2
5 is stored. The received message storage address of the memory 25 may be addresses 1 → 2 → ... In the order of selection, or may be an address previously determined by the control unit 22. The received message stored in the memory 25 is the first message described above.
By the key, the second key, or another key, they can be sequentially read and sent to the display unit 23 for display.

In this display, it is possible to change, add, or delete the received message being displayed by the third key button. That is, by turning on the third key button,
Any one of the modes of change, addition, and deletion is selected, and the received message is processed (any one of change, addition, and deletion) according to the instruction content of the operator according to the selected mode. In the change, the message being displayed is changed and then written again in the memory 25 (or the received message written in the memory 25 is erased and the changed message is written). Even if you add
Addition is performed to the message being displayed, and the message including this addition is written again in the memory 25. In the erasure, the address contents of the memory 25 that stores the message being displayed are erased.

In order to enable the change and the addition, it is necessary to provide the control unit 22 with the change and the addition processing function. Then, the received message is displayed on the display unit 23, changes or additions are made by key operation, and the changed message is displayed on the display unit 23. If the change or addition is OK, the displayed contents are confirmed and sent to the memory 25 for storage. At this time, the storage destination is preferably the address in which the received message was previously written.

The operator selects the message to be stored in the memory 25 by looking at the screen. However, the other party is registered in advance by the other party and an incoming call from the registered other party is made. There is also a method in which the control unit 22 automatically stores the received message in the memory 25. There is also an example in which this method is used in combination with a method determined by the operator.

There are cases where four key buttons are provided independently of the first to fourth keys, but about two key buttons are provided, and the combination of these key buttons and the operating procedure make it practical. It also includes the case of realizing the first to fourth keys.

Although the one-way selective calling is taken as an example, the present invention can be applied to a two-way selective calling machine that returns a simple ACK to the other party.

[0027]

According to the present invention, the received message is stored in the buffer memory, particularly the FIFO type buffer memory, and the received message to be retained is stored in another memory. It's easier. Also, the usability has improved.
