DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device such as a portable telephone.

[0002]

2. Description of the Related Art In recent years, in portable telephones, for example, U.S. Pat. S. P. A product having a plurality of personal communication numbers as described in US Pat. No. 4,677,653 and having a function of responding to communication at any personal communication number is on the market.

[0003] By the way, this personal communication number is
Corresponds to telephone numbers on general telephones.

[0004]

By the way, in the above communication device, when a user designates a predetermined personal communication number in advance among a plurality of personal communication numbers and receives a control signal corresponding to the communication number. Only a response can be made, no response can be made even if a control signal corresponding to an unspecified communication number is received, and it is not known whether or not there is an incoming call to an unspecified communication number thereafter.

Incidentally, there is a so-called voice mail service in which a caller can leave a message at the telephone office when there is no answer to the incoming call, and it is known whether or not there is an incoming call for each personal communication number. That is important.

[0006]

According to the present invention, there is provided a communication apparatus comprising: means for storing a plurality of personal communication numbers; means for restricting an incoming call to any of the stored personal communication numbers; When a control signal is received,
A means for prohibiting a response to the control signal when detecting which of the personal communication numbers corresponds to the call control signal and detecting a match with the personal communication number for which the incoming call is restricted; And a means for displaying that there is an incoming call for the personal communication number, and a means for displaying the personal communication number based on the storage means.

[0007]

The present invention is configured as described above,
When there is an incoming call to the personal communication number for which the incoming call is restricted, the display relating to the personal communication number can be performed.

[0008]

An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram of a portable radio telephone used in the U.S. cellular system. (1) is a radio section for demodulating a received high-frequency (800 MHz band) signal and modulating a transmission signal to a high frequency for transmission. Things. (2) a filter unit which filters a signal from the radio unit (1) and supplies the filtered signal to a communication control circuit (3) and an amplifier (4), and a signal from the communication control circuit (3) and an amplifier (4). Is filtered and given to the radio unit (1). The communication control circuit (3) is provided between the filter section (2) and the data bus (5) for transmitting and receiving data signals such as message data and for performing key scan of the key circuit (6) and display of the display (7). The display control is also performed. The key circuit (6) includes a numeric keypad, a redial key, a clear key, a send key, an end key, and a read key. (8) and (9) are a microphone and a speaker connected to the amplifier (1). (10) a CPU that operates according to a program written in a program memory (11) composed of a ROM, and a data memory (12) composed of the communication control circuit (3) and a RAM via a data bus (5)
And exchange data. Similarly, data is exchanged with the communication control circuit (3) and the number memory (13) composed of an EEPROM via the data bus (5). The number memory (13) has an area for storing five personal communication numbers. (14) is a bell.

FIG. 2 is a flowchart of a program of a main part at the time of an operation for setting an incoming call restriction of a personal communication number stored in the program memory (11). The operation will be described below based on this. First, for example, when the incoming call restriction number setting mode is set by simultaneous operation of the send key and the end key of the key circuit (6), the CPU (10) transmits the numeric keypad of the key circuit (6) via the communication control circuit (3). Is detected (step S-1). Here, for example, when the operation of the "1" key is detected, the processing is performed on the business 1 area of the number memory (13) (step S-).
2). In this process, if the incoming call restriction setting has already been made, the incoming call restriction is released, and if the incoming call restriction is released, the incoming call restriction setting is made. In addition, the display (7) displays as shown in FIG. 3 or FIG. After this processing, if the simultaneous operation of the send key and the end key is performed again, this mode is released and the operation moves to the next operation. However, if there is no operation, the above processing is performed again (step S-3). .

FIG. 5 is a flowchart of a main part program at the time of the calling operation stored in the program memory (11), and the operation will be described below based on the flowchart. First, in the standby mode, when a control signal for calling including a personal communication number transmitted from the base station is received, the CPU (10) controls the control provided from the communication control circuit (3) via the data bus (5). The signal is decoded, and the personal communication number included in the control signal is compared with each personal communication number stored in the number memory (14) (step T-1). Here, if a match with each personal communication number is not detected, the system returns to the standby state, and if a match is detected, it is detected whether or not the number is set to the incoming call restriction (step T-2). If the incoming call restriction is not set, the data of the area name and the display data corresponding to the personal communication number are given to the communication control circuit (3) via the data bus (5). The display (7) displays the area name (for example, business 1), and sounds an alert alert from the bell (13) (steps T-3 and T4). Thereafter, if the send key is operated, the processing shifts to the call processing. If the incoming call restriction is set, the fact that there is an incoming call to the personal communication number for which the incoming call is restricted is stored in the data memory (12) (step T-5), and the process returns to the standby state.

FIG. 6 is a flowchart of a main part of a program for confirming an incoming call to a personal communication number for which an incoming call is restricted stored in the program memory (11). Will be described.
First, in the standby state, the read key is operated,
When the CPU (10) detects this, this CPU (1)
0) is an incoming call based on the data memory (12),
Detects personal communication numbers set for incoming call restriction,
The area name corresponding to the communication number is displayed as shown in FIG. 7 (step M-1). By the way, the data memory (12)
, The number of incoming calls is also stored, so that the number of incoming calls is also displayed.

In step M-1, the data memory (1
The display is performed for every personal communication number stored in 2), for example, every two seconds, and when all displays are completed, the apparatus returns to the standby state.

A data memory (12) indicating that there is an incoming call to the personal communication number for which incoming calls are restricted.
Is cleared by simultaneous operation of the read key and the clear key.

[0014]

Since the present invention is constructed as described above, for example, when a personal communication number is divided into a business communication number and a private communication number and the incoming call restriction is set for the private communication number, the private communication number is set to the private communication number. Although the incoming call response to the personal communication number is prohibited, it can be confirmed that there is an incoming call, and the user can listen to the message of the caller by the voice mail service.
