Description

Wireless page receiver and wireless receiver

The present invention relates to radio page receivers and radio receivers, and more particularly to radio page receivers and radio receivers having a display function.

Some conventional radio call receivers have a display function that notifies a call by sound, as well as a display function on which the message signal transmitted subsequent to the receiver's call number is decoded and displayed on the display device of the receiver. .

For example, Japanese Patent Laid-Open No. 5-199163 (1993) discloses a radio call receiver having a display function for displaying a message consisting of numbers from 0 to 9 and several symbols. For example, when the telephone number 012-345-6789 is transmitted as a message, the hyphen "-" is sent to the receiver even if no message signal corresponding to the hyphen "-" after "2" and "5" is input. Is inserted between the predetermined positions.

Recently, radio word receivers in the form of arbitrary word-displays have also been developed which display a message combining a number from 0 to 9 and several symbols and Kana-letters (Japanese characters). In the radio call receiver, a schedule message composed of time information and kana information can also be easily transmitted from a general telephone terminal. For example, Japanese Patent Laid-Open No. 4-304039 (1992) discloses a radio word receiver in the form of an arbitrary word-display, in which a message composed of Kana characters and even Chinese characters can be transmitted. When a schedule message consisting of date information and other information surrounded by "[", "]" is transmitted, as in the example of "[Z24 / 1800] Christmas Party in Yokohama", the radio page receiver sends the above information to date information "December." It can also be used as an electronic notebook by recognizing 24 ^th 18:00 "and storing the schedule message in its storage device. The arbitrary word-display type radio call receiver has been widely used since the above advantages of radio call receivers have been well exploited.

Figure 1 shows the signal format of a FLEX system, which is a typical signal system used in any word-display type paging receiver. This format includes several arranged blocks using the synchronization signal as a reference and some interleave blocks contain the contents of the transfer rate and transfer bit configuration. 3 illustrates 4-bit data used in a flex system. One of the second generation wireless paging systems developed by Motorola in the United States, the flex system includes a sync signal and an address / message acknowledgment signal in one frame, and is a binary FSK or binary / photonary FSK modulation system. Use

In the conventional arbitrary word-display type paging receiver, example schedule message data such as " [01-31-15-00] caigee (meaning a conference) shown in FIG. 2 is transmitted in the signal format of FIG. This schedule message data is divided into a heading section (temporary display section) and a Ghanaian-character display section showing the contents of the schedule, which is decrypted in accordance with FIG. 3 and displayed as shown in FIG.

However, there are some problems with conventional radio call receivers. The first problem is that the operation is complicated, so that people can make mistakes when entering a schedule message from the telephone terminal. That is, for example, when sending a schedule message that a meeting is to be held at 15:00 on January 31, the format specifies a number for month, day, hour, and minute between the "[" and "]" codes. Enter the Kana information and enter "[01-31-15-00] カ イ ギ". In order to separate the numbers into months, days, hours and minutes, the operator must input a signal corresponding to "-" after "1", "31" and "15". For example, when inputting from a telephone terminal, "* 2" corresponding to "-" should be input.

The second problem is that airtime increases by that much. In the above example, the title portion (temporary display portion) of the schedule message "[01-31-15-00] Kai" is "[01-31-15-00]". When expressing this only with the codes "[", "]" and numbers, the heading is sent as "[01311500]". Thus, 14 codes, "[01311500] Kai", are transmitted as the schedule message. In the above-described FLEX system, information is transmitted using unit words, each word consisting of 32 bits and 21 bits of the 32 bits are information bits. Since one code is 4 bits, the schedule message contains 56 bits. Thus, for the schedule message, data transfer requires three words. In addition, when three "-" codes are added, 12 bits are added so the message contains 68 bits, so four words are needed for data transfer. In fact, since the number of bits increased is 21, the airtime must also be increased.

The third problem is that when sending the schedule message without adding a "-" code as in the above example, the sender can easily enter and reduce the airtime, while the owner of the receiver has the " The message is not easily readable because it is displayed without a code.

The fourth problem is that when displaying a schedule message with three "-" codes on the display device, the number of codes that can be displayed on the kana display portion is reduced to three codes, thereby reducing the kana information.

It is an object of the present invention to provide a wireless call receiver which allows the caller to easily enter a schedule message and the receiver to easily view the received schedule message while reducing the airtime required for data transmission.

It is another object of the present invention to provide a wireless receiver that allows the caller to easily enter a schedule message and the receiver to easily view the received schedule message while reducing the airtime required for data transmission.

Next, the radio call receiver of the first preferred embodiment according to the present invention will be described in FIG. 4 is a block diagram showing a radio call receiver of the first embodiment.

Referring to FIG. 4, a radio signal modulated by a call signal and a message signal following the call signal is received by the antenna 1, and amplified and modulated by the wireless device 2. The decryption apparatus 3 performs bit-synchronization and word-synchronization on the demodulated baseband signal, and then performs error correction or the like according to a predetermined coding system.

On the other hand, the unique call number of the receiver previously stored in the call number storage device 4 is read by the decryption device 3 via the control device and compared with the received call number. When the received call number matches the unique call number, a coincidence signal is sent to the control device 5 together with the message signal following the incoming call signal.

Next, the control device 5 outputs a notification signal to the speaker 10 and the LED 11 through the notification signal driver 9 to notify the reception of the message.

At the same time, the control device 5 displays the message as numeric and text information on the LCD display device 13 via the LCD driving device and controls the storage of the received message signal in the message storage device 7. Furthermore, when the received message is a schedule message, the control device displays the schedule message as numeric and text information in various display forms instructed by the LCD display device 13, and also schedule message in the schedule message storage device 6. Control the storage. In Fig. 4, a switch 8 is provided for operating the notification and resetting of the display, rereading display information, and the like.

In the first embodiment, when receiving a schedule message composed of month, day, hour, minute and kana information, each of which is two digits, as in the example of "[01311500] Kai (means a meeting)", the LCD display device 13 ) May optionally indicate "[01-31-15-00] Kaigi including three"-"or" [01311500] Kaigi not including "-". The control device 5 can edit the message signal to provide an easy-to-view indication as a schedule message or to increase the information by three codes. Also, when the message is a schedule message, the message is stored in the schedule message storage device 6 and then edited. However, the schedule message storage device 6 may be in an address area different from the message storage device 7. In other words, the schedule message storage device 6 need not be a separate memory device. In addition, the storage to the storage device 6 may be performed after the editing is completed in the control device 5.

The circuit configuration of the radio call receiver of the first embodiment can also be applied to a radio receiver such as a POCSAG system radio call device, a PHS (Personal Handyphone System), a mobile phone, a second generation radio call system FLEX-TD (Flex Time Diversity), and the like. There will be. It is not limited to only those used in radio page receivers.

In addition, the radio page receiver of the first embodiment may serve as an electronic notebook for user schedule management. That is, by displaying the schedule stored in the schedule message storage device 6 in chronological order, the user can know the schedule received by the radio call receiver in the past from the present, in the present to the future. Thus, the user can act on a schedule. In addition, by providing a peripheral key, such as a numeric key or a ten key, to a radio page receiver, the user himself can enter a schedule. Thus, comprehensive schedule management can be implemented by combining the schedule entered directly by the schedule with the schedule received by the radio page receiver.

The operation of the radio call receiver in the first embodiment together with the specific method of editing the message signal in the control device 5 will be described in FIG. 5. As shown in Fig. 5, when an address (call number) and a message are received (step 101), it is detected whether the message is configured by a format including date and time information between codes "[" and "]". (Step 102), it is determined whether or not to use the function of the present embodiment, that is, whether or not the message is a schedule message. If it is not a schedule message, the control device 5 not only displays the message on the LCD display device 13 via the LCD driving device 12 but also controls storing the message in the message storage device 7 (step ( 111)).

If it is determined that it is a schedule message, it is checked whether or not a code other than a number is included in the date and time information between the codes "[" and "]" (step 103). If included, the message is stored in the schedule message storage 6 and displayed on the LCD display 13 (step 110). If only numbers are included, the control unit 5 moves the pointer to the highest digit of the heading displayed on the LCD display 13 shown in FIG. 4, that is, the number immediately to the right of the "[" code. Reset the digit counter N to zero (step 105). Next, it is judged whether a "] " code exists at the position indicated by the pointer at that time (step 106). If there is no "]" code at that position, the digit counter N is incremented by 1 and the pointer is moved to the next lower position (step 107). If the counter N matches 2 digits of the month, day, hour, and minute of the heading (step 108), a "-" code is inserted between the position before and after moving to the lower position in the schedule message heading. (Step 109).

The same process (steps 105 to 109) is repeated. When there is a "]" code at the position indicated by the pointer, the schedule message signal is stored in the schedule message storage device 6 and the "[01-31-15-00] カ イ ギ" on the LCD display device 13. As indicated (step 110).

If the message is not a schedule message applicable to the editing function, it is stored in the message storage device 7 and displayed on the LCD display device 13 (step 111).
