The operation of the control circuit (8) in the embodiment will be described with reference to the flowcharts of FIGS. FIG. 2 shows a process of registering a caller number, a telephone number and a calling number flag, and FIG. 3 shows a process of setting a display identifier in the calling process.

The registration process of the caller number by the incoming call process will be described. The total number of caller telephone numbers registered in the caller number memory (12) is CN, and the nth telephone number is CT.
(N). The initial value of CN is 0 (S1). An incoming call is received during standby or during a call (Y in S2), and the receiving circuit (2)
The control circuit (8) detects the information element of the calling number notification of the caller on the basis of the data decoded by the TDMA circuit (4) via the terminal (Y in S3), checks the setting state of the display identifier,
If the display is permitted (Y in S4), the number of registered caller numbers CN is incremented by 1 (S5), and the telephone number is stored in the caller number memory (12) (S6).

Next, registration processing of a telephone number and a calling number flag using the ten keys (14) will be described. The total number of telephone numbers registered in the telephone number memory (16) is DN, the nth telephone number is DT (n), and the nth calling number flag is DH.
(N). The initial value of DN is 0. Numeric keypad (1

7). The control circuit (8) causes the display (10) to display the input telephone number. At this time, as shown in FIG. 6A, the display of the calling number notification is set to "notification permitted" by default (S8). Every time the setting key (20) is pressed, “notification permitted” and “notification prohibited” are switched (S
9 to S12). The displayed telephone number and calling number notification are stored in the scratch pad memory (11). The distinction between "notification permitted" and "notification prohibited" of the calling number notification is stored in the scratch pad memory (11) as a calling number flag. When the registration key (15) is pressed (Y in S13),
The registration number DN of the telephone number is incremented by 1 (S14), and the telephone number stored in the scratch pad memory (11) and the calling number flag are stored in the telephone number registration memory (16) (S15).

The setting process of the calling number identifier in the dial calling process will be described with reference to FIG. There are three types of dial transmission: manual operation using a numeric keypad (14) and automatic operation using a telephone number stored in a telephone number memory (16) or a caller number memory (12).

The telephone number to be dialed is input from the ten keys (14) (S30). The control circuit (8) causes the display (10) to display the input telephone number. At this time, as shown in FIG. 4A, the display of the calling number notification is set to "notification permitted" by default (S31).
Each time the setting key (20) is pressed, "notification permitted" and "notification prohibited" are switched (S32, S33) (switching between (A) and (B) in FIG. 4). In this way, the telephone number to be dialed and the calling number notification are displayed, and the displayed characters are stored in the scratch pad memory (11). When the call key is pressed (S34),
The calling number information element shown in FIG. 9 is coded based on the calling number flag stored in the scratch pad memory (11) (S35). That is, if the display of the calling number notification is "notification permitted", the 6th bit assigned to the display identifier is set to 0, and the 7th bit is set to 0. Set to 0. Then, the user dials the telephone number stored in the scratch pad memory (11) (S36).

Instead of a numeric keypad, a telephone number calling key (1
8) is pressed (Y in S37), the telephone number memory (1) is pressed.
The telephone number stored in the first address of 6) is read out and displayed on the display (S38). As shown in FIGS. 5 and 6, the calling number flag corresponding to the displayed telephone number is also read out. If the calling number flag is "permitted", "notification permitted" is displayed and the calling number flag is set to "prohibited". "Notification" is displayed (S39). Only one telephone number is displayed on the display (10), and other telephone numbers are displayed by operating a cursor key (not shown) (S40). Here, when the setting key (20) is pressed, the calling number notification is changed (S41, S42), and when the calling key (19) is pressed, the information according to the displayed calling number notification is coded and dialed. (S
43, S35, S36).

When the caller's number call key (18) is pressed instead of the telephone number call key (18) (Y in S44), the telephone stored in the first address of the caller number memory (12). The number is read out and displayed on the display (S4
5, S46) (see FIGS. 7 and 8). Calling number notifications all display "notification allowed". Only one telephone number is displayed on the display (10), and other telephone numbers are displayed by operating a cursor key (not shown) (S4).
7). Here, when the setting key (20) is pressed, the calling number notification is changed (S48, S49), and when the calling key (19) is pressed, the information according to the displayed calling number notification is coded and dialed. (S50, S35, S3
6).

FIG. 10 shows the processing of the originating exchange in call processing.
It will be described based on. If the call setting is performed (S60) and the calling number information element is not included in the call setting (No in S61), a default telephone number is set (S62), and a network activation is set as the network verification identifier (S63). ). If the calling number information element is included in the call setup (the presence of S61), the number verification is performed, and if it fails (failure of S64), the telephone number in the calling number information element is discarded (S65). If the number verification is successful (S64 successful), the caller ID is edited (S66). This is performed when the exchange adds an area code or the like to the calling number information element. User input, network verification is performed, and success is set for the network verification identifier (S6).
7). When the user always rejects the calling number notification contract to the network (constant rejection in S68), when the contract for each call is made but the display identifier cannot be displayed (S68).
69, each call is designated, display of S32 is not possible), or when there is no calling number information element and a default contract is not made in the network (no information element of S69, default notification of S70 is not possible), the user inputs the network verification identifier. The network is verified, and success is set (S71). This setting indicates the intention of the user to refuse the calling number notification. When the calling number notification contract is contracted to be specified for each call (specified for each call in S68), the display identifier is permitted to be displayed (display in S69 is possible), or there is no information element of the display identifier (S69).
When there is a default contract (the default notification in S70 is possible), the network verification identifier is set to network input (S72). Thereafter, a call setting request is made to the destination exchange (S73). Under the above conditions, the calling number information is notified via the network or over the network.

As described above, according to the present invention, when a call is made using the telephone number stored in the caller number memory, there is a very high possibility that the user will permit the notification of the calling number. Therefore, the calling number notification is set to be permitted as an initial state. When a call is made using the telephone number stored in the telephone number memory using the numeric keypad, the permission of the calling number notification cannot be predicted. Based on this, initial setting of permission / prohibition of the calling number notification is performed.

This initial setting is performed in steps S41, S42,
It can be changed in S48 and S50. But,
Normally, the display identifier is set as it is initially set. Therefore, the present invention controls the calling number notification by automatically controlling the display identifier.

Although the TDMA cellular communication device has been described in the present embodiment, it is easily conceivable that the present invention can also be realized in a CDMA cellular communication device or a digital communication device such as ISDN.

[0021]

According to the present invention, there is provided a storage means for automatically storing a telephone number of a caller,
By using the storage unit that stores the telephone number input with the ten keys, the setting operation of permitting / prohibiting the calling number notification for each call can be omitted, and the convenience can be improved.
