In step 3b, the position display information setting control means 40a accepts, via the console unit 42, a text input of the display data V from the user and an input of an allowable amount A (unit: [sec]) set in association with the text data. .

If necessary, image data, text data, musical score data of a ringing melody, and the like are received from the user as additional information. Here, the allowable amount A
Uses [seconds] because the location information is latitude / longitude information, but accepts input in meters,
You may make it convert into a unit of second.

In step 3c, the position display information setting control means 40a uses the position information acquired in step 3a as reference position information R, and associates the display data V and the allowable amount A received in step 3b with this. (If there is additional information, add it as well) and record it as one piece of position display information in the setting information storage area 41a. afterwards,
A call is transmitted to the set partner terminal device, the position display information recorded in the setting information storage area 41a is transmitted, and the process ends.

Next, the operation in the case where the terminal device on the transmitting side uses the terminal device on the receiving side to transmit the position display information by the processing shown in FIG. 3 will be described. FIG. 4 is a flowchart showing the processing performed during this operation. This processing is performed by the position display information recording control means 40b.

When the user operates the console unit 42 to respond to the incoming call of the terminal device on the transmitting side, the position display information recording control means 40b which detects the operation is performed.
First, in step 4a, the position display information is received from the terminal device on the transmitting side, and the process proceeds to step 4b.

In step 4b, the position display information recording control means 40b records the position display information received in step 4a in the position display information storage area 41b in association with the caller number notified at the time of the incoming call. The process ends.

Next, the operation for newly registering / editing information to be recorded in the position display information recording control means 40b using the terminal device on the receiving side will be described. FIG. 5 is a flowchart showing the processing performed during this operation. This processing is performed by the position display information recording control means 40b.

When the user operates the console unit 42 to make a request to start the above processing, the position display information recording control means 40b which has detected this request first issues a new position display to the user in step 5a. An inquiry is made on the LCD display of the console unit 42 as to whether to register information or to edit already registered information.

Here, if there is an instruction for new registration through the console unit 42, the process proceeds to step 5b, while if there is a request for editing, the process proceeds to step 5b.
e.

In step 5b, the position display information recording control means 40b detects a base station capable of communication in the vicinity, receives position information broadcast from the detected base station, and proceeds to step 5c.

In step 5c, the position display information recording control means 40b performs the following to create new position display information.
The input of the telephone number of the communication partner, the allowable amount A, and the display data V is received from the user through the console unit 42, and the process proceeds to step 5d. Here, as necessary, image data, text data, score data of a ringtone melody, and the like are received from the user as additional information.

In step 5d, the position display information recording control means 40b sets the position information acquired in step 5b as reference position information R, and associates the information received in step 5c with the position display information storage area 41b. And the process ends.

On the other hand, in step 5e, the position display information recording control means 40b reads out the information stored in the position display information storage area 41b and sends it to the console unit 42.
, And accepts designation of the position display information to be edited from the user through the console unit 42, and proceeds to step 5f.

In step 5f, the position display information recording control means 40b displays only the position display information designated in step 5e on the LCD of the console unit 42, and receives a correction instruction from the user through the console unit 42. , To 5g. The correction instruction here is correction of the corresponding telephone number, reference position information R, allowable amount A, display data V, and additional information.

In step 5g, the position display information recording control means 40b records the position display information corrected in step 5f in the position display information storage area 41b instead of the corresponding information in the position display information storage area 41b. Then, the process ends.

Next, the operation when an incoming call occurs will be described. FIG. 6 is a flowchart showing a process performed at the time of an incoming call. This process is controlled by a position display information display control unit 40c and a normal control function of the control unit 40.

First, when an incoming call is received, the position display information display control means 40c which has detected the incoming call makes a decision at step 6a.
The caller ID is received from the connected base station and the position information notified from the connected base station to the calling terminal device is also received, and the process proceeds to step 6b.

In step 6b, the position display information display control means 40c determines whether or not the position display information associated with the caller number notified in step 6a exists in the position display information storage area 41b. If the corresponding data exists, the process proceeds to step 6c. If the corresponding data does not exist, the process proceeds to step 6c.
h.

In step 6c, the position display information display control means 40c determines the reference position information closest to the position information received in step 6a among the position display information associated with the caller number notified in step 6a. Those having R are detected, and the process proceeds to step 6d.

In step 6d, the position display information display control means 40c obtains a difference between the reference position information R of the position display information detected in step 6c and the position information received in step 6a.

Then, the position display information display control means 40c
Determines whether the difference is equal to or less than the allowable amount A of the position display information detected in step 6c. If the difference is equal to or less than the allowable amount A, the process proceeds to step 6e. If the difference exceeds the allowable amount A, the process proceeds to step 6h.
Move to

At step 6e, the position display information display control means 40c displays the display data V of the position display information detected at step 6c on the LCD of the console unit 42, and proceeds to step 6f.

At step 6f, the position display information display control means 40c determines whether or not there is additional information associated with the caller number notified at step 6a.
Here, when the additional information exists, the process proceeds to step 6g, and when the additional information does not exist, the process proceeds to step 6h.

In step 6g, the position display information display control means 40c outputs the additional information associated with the caller number notified in step 6a, and proceeds to step 6h.

Here, the position display information display control means 4
0c is output by displaying it on the LCD display of the console unit 42 when the additional information is image data or text data, and is driven and controlled by the sounder of the console unit 42 when the additional information is the score data of the ringing melody. To output the melody of the incoming call.

In step 6h, the control unit 40 monitors the keys of the console unit 42 and determines whether the user responds to the incoming call. Here, if the user has performed an operation to respond to the incoming call, the process proceeds to step 6i, whereas if the user has not performed an operation to respond to the incoming call, the process proceeds to step 6j.

In step 6i, the control unit 40 performs call control as a normal control function, and when the line is disconnected, the process is terminated. On the other hand, in step 6j, the control section 40 monitors whether or not the incoming signal from the base station has stopped. Here, when the incoming signal can be received, the process proceeds to step 6h again. On the other hand, when the incoming signal can no longer be received, the process ends.

As described above, in the mobile radio terminal having the above configuration, the display data V indicating the position and the reference data indicating the reference position of the display are provided as the position display information in association with the telephone number of the caller. The position information R and the permissible amount A are stored. Then, of the position display information corresponding to the notified telephone number, the one having the reference position information R closest to the notified caller's position information is detected, and this reference position information R and the notified position are detected. When the difference from the information is equal to or less than the allowable value A, the display data V is displayed to notify the incoming call.

Therefore, according to the mobile radio terminal having the above configuration, even if the position information of the caller notified from the network side is intuitively difficult information such as the latitude / longitude information, it can cope with this in advance. It is possible to convert the information into the position information that is easy for the user to understand and to notify the user, and to easily understand and specify the position where the mobile communication terminal on the transmitting side exists.

Since the position display information is set for each caller, even if a large amount of position display information is registered, the data to be displayed can be quickly searched based on the caller number, The time required to display is short.

The position display information registered on the receiving side is
Since the receiving side can create the position information of the base station received from the base station using the reference position information R, the latitude / longitude information which is difficult to set can be easily set.

The location display information to be registered on the receiving side is created by using the location information of the base station received from the base station on the transmitting side as reference location information R and transmitted to the receiving side for setting. Therefore, it is not necessary for the called party to go to the place to be registered, and latitude / longitude information that is difficult to set can be easily set.

Further, the permissible value A can be set for each position display information.
To distinguish the east exit and the west exit, set the allowable value A small,
For a small station where it is not necessary to distinguish between exits, the allowable value A can be set relatively large, and the accuracy as position information can be increased as necessary.

Further, it is possible to store additional information in association with the caller number, and to output the information together with the incoming call. Furthermore, the notification of the location information that is easy for the user to understand is performed before answering the incoming call, so the receiving-side user estimates the request of the calling-side user according to the position of the caller without responding to the incoming call. be able to.

The present invention is not limited to the above embodiment. For example, in the above embodiment, the position information notified to the receiving side is described on the assumption that the network performs the notification based on the identification information of the base station to which the terminal apparatus of the calling side is connected. However, instead of this, for example, a configuration in which the terminal device on the transmitting side acquires its own location information from the network and transmits it to the receiving side may be used.

Further, in the above-described embodiment, the case of receiving a call has been described. However, the present invention is applicable not only to the case of receiving a call but also to a case where the position information of the terminal device on the calling side is notified after the communication is started. Needless to say. Even in this case,
Similar effects can be obtained.

In the above-described embodiment, an example has been described in which a plurality of pieces of position display information are associated with one telephone number. However, it is needless to say that only one piece of position display information may be associated.

In this case, since there is only one piece of position display information, one piece of registered information is always the closest position information. However, even if there is an incoming call from a place distant from the registered information position, erroneous display can be prevented by setting the allowable value A. It goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0078]

As described above, according to the present invention, the display information and the position information are stored in advance in the storage means in association with each other, and the position information of the transmitting side received by the reception means and stored in the storage means. When the difference from the position information is equal to or smaller than a preset allowable value, the display means displays the display information and the identification information.

Therefore, according to the present invention, even if the location information of the caller received from the base station is information that is difficult to understand intuitively, such as latitude / longitude information, it is easy for the user to associate with this information in advance. It is possible to provide a mobile communication terminal that can be converted into display information and displayed, and that can easily understand and specify the position where the mobile communication terminal on the transmitting side exists.

According to the present invention, the display information and the position information are stored in advance in the storage means in association with each other, and among the stored position information, the position information closest to the transmission side position information received by the reception means is stored. The display information associated with the position information is displayed on the display together with the identification information received by the receiver.

Therefore, according to the present invention, even if the location information of the caller received from the base station is information that is difficult to understand intuitively, such as latitude / longitude information, it is easy for the user to associate with this information in advance. It is possible to provide a mobile communication terminal that can be converted into display information and displayed, and that can easily understand and specify the position where the mobile communication terminal on the transmitting side exists.
