DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a system configuration diagram of an embodiment of the present invention. The originating subscriber 1 is connected to the exchange 3 via a subscriber circuit 2. The exchange 3 is connected to the exchange 7 via the trunk circuit 4, the relay line 5 and the trunk circuit 6. A PB receiver 8, an announcement machine 9 and a central controller 10 are also connected to the exchange 7. Further, the exchange 7 is connected to a cell site (base station) 14 via a trunk circuit 11, a relay line 12 and a trunk circuit 13. The cell site 14 is also connected to the mobile phone 100, which is a mobile station, via an antenna 15 and a radio channel 16.

Next, the operation of the present invention will be described with reference to FIG. The mobile phone 100 is now busy. Without knowing this state, the calling subscriber 1 calls the mobile phone 100. The telephone number of the called party dialed is the subscriber circuit 2
Is received by the exchange 3 and is connected to the exchange 7 via the trunk circuit 4, the trunk line 5, and the trunk circuit 6.
B receiver 8. Based on the received telephone number, the central control unit 10 sees the use state of the called mobile phone 100 and identifies that it is busy. The caller is busy and prompts the message sending operation ”is sent via the trunk circuit 6, the trunk line 5, the trunk circuit 4, the exchange 3, and the subscriber circuit 2. The calling subscriber 1 sends a message number corresponding to a predetermined message to the exchange 7. This message number is received by the PB receiver 8 connected to the exchange 7 via the subscriber circuit 2, the exchange 3, the trunk circuit 4, the trunk line 5, and the trunk circuit 6. The central controller 10
The trunk circuit 1 includes the message number received via the PB receiver 8 and the telephone number of the calling subscriber 1 obtained by the exchange 7 requesting the exchange 3 via the trunk circuits 6 and 4.
1, to the cell site 14 via the relay line 12 and the trunk circuit 13. The cell site 14 transmits this message number and the telephone number of the calling subscriber to the radio channel 16 via the antenna 15 and then to the mobile telephone 100.
At this time, the mobile phone 100 generates a message reception report tone to notify the busy subscriber that the message has been received, and the “message number” pair “prestored” based on the received message number. The message is taken out from the exchange table of "message contents" and displayed together with the telephone number of the calling subscriber who received the message.

Here, the configuration and operation of the automobile telephone 100 will be described in detail. 2 is a block diagram of the automobile telephone 100, and FIG. 3 is an external view thereof. Each unit in the automobile telephone 100 is connected via the system bus 108, and according to the program stored in the memory (MEM) 111,
It is controlled by the CPU 112. Display 104
Is controlled by the display controller 105, and includes a message display unit 104a and a message reception display 104b. The keypad 107 is composed of keys of 10 numbers and 2 symbols, and is controlled by the keypad button speaker controller 106.
The button section 117 includes a message read button 117a, a message left move button 117b, and a message right move button 117c.
It is controlled by the speaker controller 106. The reception / transmission unit 102 transmits and receives the radio channel 16 via the antenna 101.

FIG. 4 is a diagram showing a format of data and an order transmitted on the radio channel 16. This format is called format voice channel data 200, and has a number and number display section (LOCA).
L) 202 and order instruction display unit (ORDQ) 203
And an order display unit (ORD) 204.

Next, the operation will be described. The telephone number of the calling subscriber 1 is set in the numbers and number display section 202 of the forward voice channel data 200 by three digits from the last digit,
It is transmitted to the mobile phone 100 in three times. For example, if the telephone number is "123-4567", then "567"
Is sent the first time, "234" is sent the second time,
"1" is transmitted the third time. Numbers are displayed in binary for each digit. For example, "567" is "0101 0110".
0111 ”. Car phone 1 for these three transmissions
In order to identify 00, the first, second, and third transmissions are displayed by 8 bits, which is the total of 3 bits and 5 bits of the order instruction display unit 203 and the order display unit 204, respectively. The first transmission is displayed as "000-00011", the second transmission is displayed as "001-00011", and the third transmission is displayed as "010-00011". The message number sent from the calling subscriber 1 is the number and number display section 202 of the forward voice channel data 200.
Is set to. For example, the message number “100” is displayed as “0000 0110 0100”. The order display section 204 of the forward voice channel data 200 distinguishes the binary data received by the mobile phone 100 so that it can be identified whether it is a telephone number or a message number. The telephone number is displayed as "00011" and the message number is displayed as "11110".

The forward voice channel data 200 on the radio channel 16 is received by the reception / transmission unit 102 through the antenna 101 and sent to the order / data detection unit 103 via the system bus 108. The order / data detection unit 103 includes a number / number display unit 202,
The order instruction display unit 203 and the order display unit 204 are detected and sent to the order / data translation unit 110 via the system bus 108. The translated telephone number is sent to the display controller 105 via the system bus 108. The message number is extracted from the message number-message content exchange table 109, and the message content is sent to the display controller 105 via the system bus 108. FIG. 5 shows a configuration example of the message number-to-message content conversion table 109. Message contents 109b are registered in advance for message numbers 109a of 1 to 100, respectively.

The display controller 105 is
The message reception display 104b on the display 104 is used to notify the mobile telephone subscriber that the telephone number and message of the calling subscriber 1 have arrived at the mobile telephone 100.
Turn on. At the same time keypad, button, speaker,
The controller 106 causes the speaker 127 to sound a message reception report tone. The button unit 117 during or after the conversation by the subscriber of the mobile phone 100.
When the message read button 117a is pressed, the keypad button speaker controller 106
Detects that the message read button 117a has been pressed and sends the detection information to the display controller 105 via the system bus 108. The display controller 105 sends the received telephone number and message content 109b to the message display unit 104a,
Display it. Furthermore, when the message left move button 117b or the message right move button 117c is pressed as necessary, the message display unit 1 is operated by the same operation as described above.
The message on 04a moves left and right. That is, when the length of the displayed message exceeds the length of the message display unit 104a, the message right move button 117c is displayed.
By pressing, the excess message can be displayed on the display unit. When returning to the initially displayed state, the message left move button 117b is pressed.

By the above operation, the telephone number and message of the calling subscriber 1 are displayed on the automobile telephone 100.

[0015]

As described above, according to the present invention, it is possible to send a message to a mobile station (automobile telephone subscriber) who is busy, so that the calling subscriber can talk to an empty party. There is an effect that a message to be transmitted can be immediately displayed with a message reception report sound on the mobile phone with a display of the other party who is busy without waiting.
