DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the configuration of an embodiment of a mobile telephone apparatus according to the present invention, together with an example of the system flow of the entire telephone system. The CNT is an incoming call display control apparatus provided in the mobile station MT. . Incoming call display control device CNT
Is storage means A for storing a plurality of sets of a telephone number of a destination and a character string such as the name of the destination, and a calling-side telephone number is transmitted from the base station ST when the mobile station MT receives a call. At this time, a search means B for searching whether or not the calling telephone number is stored in the storage means A, and the search means B finds that the same telephone number is stored, and And a display control means C for displaying a character string stored in the storage means A on a display DP provided in the mobile device MT. Hereinafter, the operation of the present embodiment will be described.

When a subscriber of the general telephone UT dials the telephone number of the mobile unit MT from the general telephone UT to call the mobile unit MT, the subscriber is connected to the base station ST of the telephone system, and an incoming call request 1 in FIG. Sent out. The base station ST sends an announcement 2 to the general telephone UT, and requests that a caller-side telephone number to be sent when calling the corresponding mobile station MT be input. When the subscriber of the general telephone UT dials or inputs his / her own telephone number after hearing the announcement 2, this is transmitted to the base station ST as the telephone number 3 of the calling side. Note that if the base station ST can automatically recognize the telephone number of the caller, the above procedure is unnecessary.

When the base station ST receives the calling telephone number 3, the base station ST starts an incoming call operation to the mobile station MT, and first sends an incoming call signal 4 to the mobile station MT. In response to this, the mobile station MT
Returns an incoming call response 5 to the base station ST. Next, the base station ST sends a call channel (CH) designation 6 to the mobile station MT to designate a channel to be used during a call. The mobile station MT performs channel switching in response to this, and the base station ST checks whether or not the mobile station MT has switched the channel to the specified communication channel based on the presence or absence of the communication channel tone 7. Phone number 8 and ringer ringing request 9
To the mobile device MT. In the mobile device MT, the ringer sounds in response to the ringer sound request 9. Further, the search means B searches the storage means A using the caller-side telephone number 8 as a key. If the same telephone number as the caller-side telephone number 8 and a character string corresponding thereto are stored, the character string is displayed. Is passed to the control means C, and the display control means C transmits the calling telephone number 8
And the above character string is displayed on the display device DP. The display of the calling side telephone number and the character string enables the user of the mobile device MT to know very easily who has received the call. After that, when the off-hook signal 10 is transmitted from the mobile device MT, the base station ST recognizes that the connection has been made on the communication channel, and transmits the line connection completion signal 11 to the general telephone UT. Thus, the general telephone U
A communication state is established between T and the mobile device MT.

FIG. 2 is a system flow showing another embodiment for transmitting a calling telephone number to a mobile station MT. Unlike FIG. 1, when there is no response from the mobile station MT to the incoming call, an announcement 12 is sent to the general telephone UT and the calling telephone number 3 is transmitted.
The base station ST sends this to the mobile station MT as the calling telephone number 8 and then sends the end signal 13 to terminate the line connection. Mobile device MT of this embodiment
Has an automatic incoming call receiving function for receiving an incoming call when a user is absent, and can be used when a calling side telephone number 3 (for example, a DTMF signal) input from a general telephone UT can be received as it is. The mobile device MT stores the received calling side telephone number 8 in the memory and displays a character string indicating that there is an incoming call, and responds to the subsequent key operation by the user to correspond to the calling side telephone number 8. Then, the character string stored in the storage means is searched, and if registered, only the character string and the calling party telephone number or character string are displayed.

FIG. 3 is a block diagram showing an example of the configuration of the mobile device MT. An antenna 20, a radio unit 21, a control unit 22, a memory 23, an input unit 24, a display unit 25, a transmitter 26, a receiver 27 and a ringer 28. 1 is realized using a part of the memory 23, for example, a memory unit 23a constituted by an EEPROM, and the search unit B and the display control unit C are realized as one function of the control unit 22. The storage of the set of the telephone number and the character string in the memory unit 23a is performed by operating a key provided on the input device 24 under the control of the control unit 22. It has a repertoire memory for storing a telephone number of a destination used at the time of calling and a character string such as a name of the destination for identifying the destination, and writing data to the repertoire memory. In a mobile device having a so-called repertoire function in which reading and displaying on a display can be performed by key operation, it is preferable to use a repertoire memory as the memory unit 23a. The display device 25 corresponding to the display device DP has a display surface having upper, middle, and lower display areas as shown in FIG. 4, for example. , A character string indicating the telephone number of the person is displayed at the bottom.

FIG. 5 is a flowchart showing an example of the processing of the control unit 22. Hereinafter, the operation of one embodiment of the mobile station MT of FIG. 3 will be described with reference to FIG. Upon receiving an incoming call signal from the base station ST (S1), the mobile station MT sends an incoming call response signal to the base station ST (S2), and assigns a communication channel (CH) from the base station ST to assign a channel used during a call. ) When the designation is received (S3), the channel is switched to the designated communication channel (S6), and a communication channel tone is transmitted (S7).
If the communication channel designation is not received within a predetermined time after the transmission of the call response signal, a timeout occurs (S4), and a standby state is set (S5).

When the base station ST receives the call channel tone, it sends out a caller telephone number and a ringer sound request signal. When receiving the caller telephone number (S8), the mobile device MT determines whether or not the current mode of the mobile device MT is an automatic incoming call mode in which an incoming call can be received when the user is absent (S1).
1) If it is not in the automatic incoming call mode, it is checked whether or not the same telephone number as the received calling side telephone number is registered in the memory unit 23a (S12). The character string registered in the memory unit 23a in a pair with the calling telephone number is displayed on the display 25 as shown in FIG. 4 (S13). Note that only the character string may be displayed in step S13. If the same telephone number is not registered, only the received calling telephone number is displayed on the display 25 (S14). On the other hand, if in the automatic incoming call mode, the received calling side telephone number is stored in a predetermined area 23b of the memory 23 (S15), and a character string indicating that there is an incoming call, for example, "CALLED" is displayed on the display 25. (S16). The calling telephone number stored in the area 23b of the memory 23 in the process S15 can be displayed on the display 25 by operating the keys of the input unit 24. At this time, the memory unit 23a is searched and the calling telephone number is searched. If a string that is paired with is stored,
The character string may be displayed on the display 25 together. It is also possible to display only the character string and omit the display of the caller telephone number. Through the above processing, it is possible to later confirm who has received the call. Also, instead of displaying a character string such as 'CALLED' in step S16, a character string that is paired with the current calling telephone number or the character string and the calling telephone number may be displayed on the display unit 25. good.

When the ringer ringing request signal transmitted from the base station ST is received (S9), the ringer 28 is sounded (S17). If the user responds to the ringing, ie, goes off-hook (S18), the off-hook is performed. A signal is transmitted to the base station ST (S19), and thereafter, a call state is entered (S20).
This completes the incoming call connection operation.

FIG. 6 is a flow chart showing a processing example of another embodiment of the control unit 22 of the mobile unit MT of FIG. 3, in which the same reference numerals as those in FIG. 5 denote the same parts, and the steps S30 to S36 are the same as those in FIG. Different. In this embodiment, when the calling telephone number is received (S
8) If the corresponding telephone number is registered in the memory unit 23a (S30), the calling telephone number and the corresponding character string are displayed on the display 25 as in FIG. 5 (S3).
1) If the corresponding telephone number is not registered (S3
0), a call termination operation is performed (S32). When a ringer sound request signal is received (S9), a ringer sound is emitted for two cycles (S33), and an off-hook signal is sent to the base station ST only when the calling telephone number is being displayed on the display 25 (S34). The call is sent out (S35), and the call is automatically placed in a call state (S36). According to this embodiment, the memory unit 23a
By registering the name of the other party you want to talk to in advance in correspondence with the phone number, only incoming calls from that person can be accepted, and incoming calls from other people can be rejected without any operation. There is. In the process S31, only the character string may be displayed.

[0018]

As described above, in the mobile telephone apparatus of the present invention, the telephone number coincident with the calling telephone number transmitted from the base station at the time of the incoming call, and the name of the other party to be paired with the telephone number. If the character string is stored in the storage means,
Since the character string is displayed on the display, it is possible to inform the user of the telephone call from the user more specifically and easily.

The following effects can also be obtained. 1. If the same telephone number is not found by the search means, the call termination operation is automatically performed, and it is possible to prevent an idle phone call without any operation. 2. When the same telephone number is retrieved by the retrieval means, the telephone is automatically placed in the telephone call state, so that the telephone telephone becomes the telephone call state without any operation, so that the operability can be improved. 3. When the user does not answer at the time of receiving the call, the caller's telephone number is received from the base station and stored, and the character string stored in the storage means corresponding to the caller's telephone number is operated by the user. In the configuration of displaying on the display, even if the user does not respond to the telephone call, the user can confirm who the call came from by performing a predetermined operation. 4. When the user does not answer the incoming call, the character string stored in the storage means is displayed on the display corresponding to the caller's telephone number. Thus, the user can confirm the caller from the character string displayed on the display without any operation. 5. When the user does not answer at the time of the incoming call, the fact that there is an incoming call is displayed on the display unit, and the character string stored in the storage means is displayed by the user's operation in correspondence with the calling telephone number. In the configuration of displaying on the display, in addition to the effect of 3, it is possible to know from the display on the display that a call has been received from someone. 6. In a configuration using storage means (a repertoire memory in the embodiment) for storing a plurality of sets of telephone numbers and corresponding character strings used when making a call from a mobile device, the search telephone number is used for calling. Since it is the same as that used occasionally, the capacity of the storage means can be reduced, and the size of the mobile device can be reduced. In addition, the user can input the telephone number at one time, and the operability is improved.
