DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio selective call receiver with a display, and more particularly to a method for selectively storing similar or limited messages.

[0002]

2. Description of the Related Art In a conventional radio selective call receiver with a display, a received message can be stored in a memory and displayed after reception. In this case, if the same message is re-received, the message is not newly stored in the memory, but otherwise the message is stored in the memory every time a new message is received.

FIG. 4 is a block diagram showing a configuration example of a conventional radio selective call receiver with a display. In FIG. 4, a radio signal A received by an antenna 1 is amplified and demodulated by a radio unit 2 and input to a decoder 4 as a digital signal B. The decoder 4 compares the address contained in the digital signal, that is, the selective calling code, with its own address C stored in the ID memory 5, and, when receiving its own address, changes the message code D attached to the address code into a message. A control signal (A) for controlling the notification display means 7 is stored in the memory 6 and the notification and the message E are displayed. Reading C of the self address from the ID memory 5 and reading and writing D of the message from the message memory 6 depend on control signals (i) and (u) of the decoder. If the received message is stored in the message memory 6, the messages D and E stored in the message memory 6 can be displayed on the notification display means 7 by the control signals (U) and (A) of the decoder 4.

[0004]

In a conventional radio selective call receiver with a display, when a large number of similar messages or messages having a content that changes every moment with respect to a specific matter are received, a message which is less necessary as information is provided. There are disadvantages that many confusing messages are stored, and selection of valid messages is troublesome and limited message memory cannot be used effectively.

Therefore, the technical problem of the present invention is that the message is limited to a specific character and a symbol string. That is, for a message relating to a specific matter, only one latest message is always stored, and a similar message is stored. Also, when receiving a lot of messages that change from moment to moment about a particular matter, the information is automatically removed from old or confusing messages that are less necessary.
It is another object of the present invention to provide a radio selective call receiver with a display which makes it easy to select an effective message even when displaying a message and can effectively use a limited message memory.

[0006]

SUMMARY OF THE INVENTION According to the present invention, there is provided a radio selective calling receiver with a display, comprising:
A second memory for storing the received message; a message matching unit for determining whether the specific character and the symbol string are included in the received message; If no character or symbol string is included, the received message is stored in the second memory, and the first message already including the specific character and symbol string is stored in the second memory. And if it is determined that the second message newly received includes the specific character and symbol string, the first message is deleted and the second message is deleted.
Has a message and the second memory control means for storing in said second memory, the specific character and symbol strings, tables
It is characterized by being included in the indicated message .

[0007]

[0008]

[Action] with display radio pager of the present invention, it is determined whether it contains a specific character and symbol groups in the received message, a particular character及the received message
If the received message is not
The second message is stored in the second memory, the first message including the specific character and symbol string is already stored in the second memory, and the specific character and symbol string is included in the newly received second message. If it is determined that the message is included, the first message is deleted and the second message is stored in the second memory, so that the first message is limited to a specific character and a symbol string, that is, the specific message When a new message is received, the old message stored in the message memory is deleted, and only the latest message can be stored.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an example of the configuration of a radio selective call receiver with a display according to the present invention. As shown in FIG. 1, a radio signal a received by an antenna 1 is amplified and demodulated by a radio unit 2 and input as a digital signal b to a decoder 4 which is the core of the control unit 3. The decoder 4 compares the digital signal b, that is, the address included in the selective calling code, with its own address c stored in the ID memory 5, and when receiving its own address, it changes the message code accompanying the address code into a message. The information is stored in the memory 6 and the notification display means 7 is controlled (A) to display the notification and the message e.

The reading of the self address c from the ID memory 5 is controlled by the decoder (a). If the received message is stored in the message memory 6, the decoder 4
(C), the messages d and e stored in the message memory 6 can be displayed on the notification display means.

When the received messages f, g, h are stored in the message memory 6, the message f received by the decoder 4 is first read from the character / symbol string memory 10 by the message collating means 8; It checks whether the character and the symbol string i are included, and outputs the result of the check and the message g to the message memory control means 9.

If the specific character and the symbol string are not included in the collation result, the message memory control means 9 stores the received message h in the message memory 6 (E). Is contained, the message memory control means 9 deletes the message containing the same character and symbol string already stored in the message memory 6 and stores the message h received from (e) in the message memory 6 ( E).

FIG. 2 is a flowchart showing an example of the operation of the radio selective call receiver with display of FIG. To display a message already stored (step 30)
1) first displays the latest message (step 30)
2). When displaying the newest message and another message (step 303), the message with the memory number indicating the message storage location allocated to the message memory is displayed in order from the next message (step 304).

Now, upon receiving the selective call code for its own address (step 305), it is first determined whether a specific character and symbol string stored in the character / symbol string memory is included in the received message. Are compared (step 306). In this example, specific characters and symbol strings
(Yen): ""＄
If "(yen):" is not included, only a new message is stored in the message memory (step 307). However, if the received message includes "(yen):", the message memory is further stored. It is checked whether a message including "@ (yen):" is stored in the message (step 30).
8) If there is a message including "$ (yen):", the message is deleted and the received message is stored in the message memory (step 309). Of course, "＄
If the message is not in the message memory containing the message containing (yen) :, the received message is simply stored in the message memory (step 307).

FIG. 3 is a diagram showing a state of message display of an example of the radio selective calling receiver of FIG. FIG. 3A shows an example in which a message stored in the message memory is displayed until a new message is received. In this state, if a message “＄ (yen): 140 yen” is received, the device as shown in FIG.
The message 21 displayed in FIG. 3A is deleted because a new message including (circle): is received, and the message 22 shown in FIG. 3B is stored.

[0017]

As described above, the radio selective call receiver with display of the present invention has a first memory for storing a specific character and a symbol string, and a second memory for storing a received message.
And a means for determining whether or not a received message contains a particular character and symbol string.
The first message including a specific character and a symbol string is stored in the memory of the first embodiment, and it is determined by the message matching unit that the newly received second message includes the specific character and the symbol string Has means for deleting the first message and storing the second message in the second memory, so that the message is limited to a specific character and a symbol string, that is, a message relating to a specific matter is newly received. The old message stored in the message memory is deleted and only the latest message is stored. Therefore, it is limited to a specific character and a symbol string, that is, only one latest message is always stored for a message related to a specific matter, and a similar message or a message having a content that changes every moment for a specific matter is stored. Even when receiving a large number of messages, old or confusing messages that are not necessary as information are automatically excluded, and effective message selection is easy when displaying messages, and limited message memory is effectively used. There is an effect that can be done.
