Description

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 the message is received. In this case, when exactly the same message is received again, it is not stored in the memory newly, but in other cases, the message is stored in the memory each time it is newly received.

FIG. 4 is a block diagram showing a configuration example of a conventional radio selective call receiver with a display. In FIG. 4, the radio signal A received by the antenna 1 is amplified and demodulated by the radio unit 2 and input to the decoder 4 as a digital signal B. When the decoder 4 collates the address included in this digital signal, that is, the selective calling code, with its own address C stored in the ID memory 5, and when it receives its own address, it sends a message code D accompanying the address code as a message. The control signal (a) for storing the information in the memory 6 and controlling the notification display means 7 is output to display the notification and the message E. The reading C of the self address from the ID memory 5 and the reading and writing D of the message from the message memory 6 depend on the control signals (I) and (U) of the decoder. If the received message is stored in the message memory 6, the message D, 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 the conventional radio selective call receiver with a display, when a large number of similar messages or messages with a content that changes from moment to moment regarding a specific matter are received, a message or a message that is not necessary as information is received. Many confusing messages are stored, which makes it difficult to select valid messages and the limited message memory cannot be used effectively.

Therefore, the technical problem of the present invention is that it is limited by a specific character and symbol string, that is, for a message relating to a specific matter, only one latest message is always stored, and similar messages are stored. Also, when receiving many messages with contents that change from moment to moment regarding a particular matter, the information is automatically excluded from old messages and confusing messages that are not necessary,
An object of the present invention is to provide a radio selective call receiver with a display, which makes it easy to select an effective message when displaying a message and can effectively use a limited message memory.

[0006]

A radio selective call receiver with a display according to the present invention is a radio selective call receiver with a display, comprising: a first memory for storing a specific character and symbol string;
A second memory for storing the received message; a message collating means for judging whether the received message contains the above-mentioned specific character and symbol string; and a second memory based on the judgment result of the message collating means. Second
Second memory control means for controlling the storage of said message in said memory.

In the radio selective call receiver with display of the present invention, the message collating means has the first message including the specific character and symbol string already stored in the second memory, and When it is determined that the newly received second message includes the specific character and symbol string, the second memory control unit erases the first message and deletes the second message. Are stored in the second memory.

[0008]

The radio selective call receiver with display according to the present invention determines whether or not the received message includes a specific character and symbol group, and already includes the specific character and symbol string in the second memory. If it is determined that the first message is stored and the newly received second message contains a specific character and symbol string, the first message is erased and the second message is replaced with the second message. By storing it in the second memory, it is limited by a specific character and symbol string, that is, when a message regarding a specific matter is newly received, the old message stored in the message memory is deleted and one latest message is deleted. Can only be remembered.

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

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

When storing the received messages f, g, and h in the message memory 6, first, the message f received by the decoder 4 is read from the character / symbol string memory 10 by the message collating means 8 (d) specific It collates whether the character and the symbol string i are included, and outputs the collation result and the message g to the message memory control means 9.

If the collation result does not include the specific character and symbol string, the message memory control means 9 stores the received message h in the message memory 6 (e). Message is included in the message memory 6, the message memory control means 9 erases 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 flow chart showing an example of the operation of the radio selective calling receiver with a display shown in FIG. To display a previously stored message (step 30
1) first displays the latest message (step 30).
2). When the latest message and another message are displayed (step 303), the message number assigned to the message memory, which indicates the message storage location, is displayed in order from the next message (step 304).

Now, when the selective call code for its own address is received (step 305), first of all, is a predetermined character and symbol string stored in the character / symbol string memory predetermined and included in the received message? Are compared (step 306). In this example, a specific character and symbol string is "$
(Yen): ”. The received message says "$
If (yen): is not included, a new message is simply stored in the message memory (step 307), but if the received message contains $ (yen) :, further message memory is stored. Check if a message containing "$ (yen):" is stored in (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 it is not in the message memory including the message including (yen) :, the received message is simply stored in the message memory (step 307).

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

[0017]

As described above, the radio selective calling receiver with a display of the present invention has a first memory for storing a specific character and symbol string and a second memory for storing a received message.
And a means for determining whether the received message contains particular character and symbol strings, and
The first message containing the specific character and symbol string is stored in the memory of and the message collating means determines that the newly received second message contains the specific character and symbol string. Is provided with means for erasing the first message and storing the second message in the second memory, so that it is limited by a specific character and symbol string, that is, when a message concerning a specific matter is newly received. The old message stored in the message memory is erased so that only the latest message is stored. Therefore, it is limited to a specific character and 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 from moment to moment regarding a particular matter is stored. Even if a large number of messages are received, old messages and confusing messages, which are rarely needed as information, are automatically excluded, effective messages can be easily selected when displaying messages, and limited message memory can be effectively used. There is an effect that you can.
