Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 illustrates the configuration of an embodiment of the incoming call display control device of the present invention together with an example of the system flow of the entire car telephone system. be. This incoming call display control device CNT includes a storage means A for storing a plurality of sets of character strings such as the telephone number of the other party and the name of the other party, and a storage means A for storing a plurality of sets of character strings such as the telephone number of the other party and the name of the other party, and a call receiving unit that transmits a call from the base station ST when the mobile phone mobile unit MT receives a call. When the calling side telephone number is sent, the searching means B searches whether the calling side telephone number is stored in the storage means A, and the searching means B checks whether the same telephone number is stored in the storage means A. Display control means C displays the character string stored in the storage means A in pair with the telephone number on the display DP provided in the mobile phone MT.
It is made up of. The operation of this embodiment will be explained below.

When a subscriber of a regular telephone UT dials the telephone number of the mobile telephone MT from the regular telephone UT in order to call the mobile telephone MT, the subscriber calls the base station ST of the mobile telephone system.
A line connection is established with the caller, and the incoming call request ■ in the figure is sent out. The base station ST sends an announcement ■ to the general telephone UT,
The user is requested to input the calling party's telephone number, which is sent out when calling the corresponding mobile phone MT. When the subscriber of the regular telephone UT dials his own telephone number or presses a key after hearing the announcement (■), this is sent to the base station ST as the calling party's telephone number (■). Note that if the base station ST can automatically recognize the calling party's telephone number, the above procedure is not necessary.

When the base station ST receives the calling party's telephone number ■, it starts an incoming call operation to the mobile phone MT, and first sends an incoming call signal ■.
is sent to the mobile phone MT. In response, the mobile phone IaMT returns an incoming call response ■ to the base station ST. The base station ST then sends a call channel (CH) designation ■ to the mobile phone MT to select the channel to be used during the call. specify. The mobile phone iMT performs channel switching in response to this, and the base station ST checks whether the mobile phone MT has switched to the specified communication channel by checking the presence or absence of the communication channel tone ■, and sends a notification channel tone. If available, caller's phone number■ and ringer ringer request■
and is sent to the mobile phone MT. The mobile phone MT makes a ringer sound in response to the ringer sound request (2).

In addition, the search means B searches the storage means A using the calling party's telephone number ■ as a key, and if the same telephone number as the calling party's telephone number ■ and a character string paired with it are stored, that character string is displayed. The information is passed to the control means C, and the display control means C displays the calling party's telephone number ■ and the above character string on the display DP. By displaying the caller's telephone number and character string, the user of the mobile phone MT can very easily know from whom the call is received. Note that when an off-hook signal [phase] is subsequently sent from the mobile phone MT, the base station ST recognizes that a connection has been made on the communication channel, and sends a line connection completion signal ■ to the general telephone UT. As a result, a communication state is established between the general telephone UT and the mobile phone MT.

FIG. 2 is a system flow showing another embodiment for transmitting the calling party's telephone number to the mobile mobile phone MT. Unlike in Figure 1, when there is no response from the mobile phone MT to an incoming call, an announcement @ is sent to the single ship phone UT and the calling party's telephone number ■ is input, and this is the calling party's telephone number ■.
As base station ST is mobile phone mobile I! After sending the call to the MT, a call termination signal 0 is sent to terminate the line connection. The mobile phone 4111MT of this embodiment has an automatic call receiving function that allows the user to receive calls when the user is not present, and the general telephone U
This can be used when it is possible to receive the calling party telephone number (for example, a DTMF signal) input from T as is. The mobile phone MT stores the received caller's telephone number ■ in its memory, displays a character string indicating that there is an incoming call, and then displays the caller's telephone number ■ in response to subsequent key operations by the user. A character string stored in the storage means is searched in response to the above, and if registered, only that character string and the calling party's telephone number or character string are displayed.

FIG. 3 is a block diagram showing an example of the configuration of the mobile phone MT, in which the antenna 20. Wireless section 21° control section 22. Memory 23. Input device 242 display 25, transmitter 26. It consists of a receiver 27 and a ringer 28. The storage means A in FIG. 1 is realized by using a part of the memory 23, for example, a memory section 23a constituted by an EEPROM, and the search means B and the display control means C are realized as one function of the control section 22. The combination of a telephone number and a character string is stored in the memory section 23a by operating keys provided on the human power generator 24 under the control of the control section 22. In addition,
It has a repertoire memory that stores the telephone number of the other party used when making a call and a character string such as the name of the other party for identifying the other party in pairs, and writes data to this repertoire memory. In a car phone mobile device that has a so-called repertoire function that allows display on the readout 9 display by key operation, the repertoire memory is stored in the memory section 2.
It is preferable to use it as 3a. In addition, the display 25 corresponding to the display DP has a display surface having upper, middle, and lower display areas as shown in FIG. A character string indicating whose phone number it is is displayed at the bottom.

FIG. 5 is a flowchart showing an example of the processing of the control unit 22,
Hereinafter, with reference to FIG. 5, the car telephone mobile station MT of FIG.
The operation of one embodiment will be explained. When the mobile phone MT receives an incoming call signal from the base station ST (Sl), it sends an incoming call response signal to the base station ST (S2), and receives a communication channel (S2) from which the base station ST assigns a channel to be used during a call. CH) designation is received (S3), the communication channel is switched to the specified communication channel (S6), and a communication channel tone is transmitted (S7). Note that if the call channel designation is not received within a certain period of time after sending the incoming call response signal, a timeout will occur.
4), the standby state is entered (S5).

When the base station ST receives the communication channel tone, it sends out the calling party's telephone number and a ringer request signal.

When the mobile phone MT receives the calling party's telephone number (S8), it determines whether the current mode of the mobile phone MT is an automatic call receiving mode that allows receiving calls when the user is not present (5ll).
If the automatic call receiving mode is not in effect, it is checked whether the same telephone number as the received caller's telephone number is registered in the memory unit 23a (S12), and if it is registered, the caller's telephone number and the caller's telephone number are checked. Memory section 2 paired with phone number
The character string registered in 3a is displayed on the display 25 as shown in FIG. 4 (S13). Note that it is also possible to display only the character string in this process S13. Further, if the same telephone number is not registered, only the received calling party telephone number is displayed on the display 25 (S14). On the other hand, if you are in automatic call receiving mode, the received caller's phone number is stored in memory 2.
515), and displays a character string, for example, "CALLED", on the display 25, which means that there is an incoming call (S16).

The calling party's telephone number stored in the area 23b of the memory 23 in process S15 can be displayed on the display 25 by key operation of the input section 24, and at the same time, the memory section 23a is searched and the calling party's telephone number is displayed. If a character string paired with is stored, the character string may also be displayed on the display 25.

Note that by performing a process such as 0 or more in which only the character string is displayed and the display of the calling party's telephone number is omitted, it is possible to later confirm who received the call. Alternatively, instead of displaying a character string such as °CALLED' in step S16, a character string paired with the current calling party's telephone number, or a character string and the calling party's telephone number may be displayed on the display 25. good.

Further, upon receiving a ringer sound request signal sent from the base station ST (S9), the ringer 28 is made to sound (317).
