DETAILED DESCRIPTION OF THE INVENTION
A communication terminal according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration, and here, a mobile radio terminal apparatus using a CDMA system as a communication system is taken as an example.
[0015]
A radio frequency signal received from the space by the antenna 1 is input to the antenna duplexer 2. The antenna duplexer 2 includes a reception filter 21 and a transmission filter 22.
[0016]
Among the radio frequency signals input from the antenna 1, a radio frequency signal in a band transmitted from a base station (not shown) passes through the reception filter 21 and is output to the reception unit (RX) 3. The radio frequency signal is not input to the transmission unit (TX) 5 described later by the transmission filter 22.
[0017]
The receiving unit 3 mixes the radio frequency signal with the reception local oscillation signal input from the frequency synthesizer (SYN) 4 and converts the frequency into an intermediate frequency signal. The frequency of the reception local oscillation signal generated by the frequency synthesizer 4 is controlled by a control voltage from the control unit 40.
[0018]
The intermediate frequency signal obtained by the receiving unit 3 is subjected to orthogonal demodulation processing in the CDMA signal processing unit 6 and then subjected to despreading processing, and converted into data of a predetermined format corresponding to the data rate. The
[0019]
Of the conversion results, received voice data related to voice communication is output to the voice code processing unit 7, and data indicating the data rate is output to the control unit 40 as a received data rate.
[0020]
Of the above conversion results, caller number data and caller location information data notified at the time of incoming call, and base station location information (latitude / longitude information) data added to the signal by the base station to which it is connected Is output to the control unit 40.
[0021]
The voice code processing unit 7 performs a decompression process on the received data obtained by the CDMA signal processing unit 6 according to the received data rate notified from the control unit 40, and displays the processing result as a PCM code processing unit. 8 is output.
[0022]
The PCM code processing unit 8 decodes the reception data expanded by the voice code processing unit 7 to obtain an analog received signal. The analog reception signal is amplified by the amplifier 9 and then output from the speaker 10 as a loud voice.
[0023]
On the other hand, the input voice of the speaker is inputted as an analog transmission signal through the microphone 11, amplified to an appropriate level by the amplifier 12, and then subjected to PCM encoding processing by the PCM code processing unit 8 to obtain transmission voice data. It is output to the voice code processing unit 7.
[0024]
The voice code processing unit 7 adds its own position information data to the transmission voice data output from the PCM code processing unit 8 to form transmission data. Then, the energy amount of the input voice is detected from the transmission voice data, the data rate is determined based on the detection result, and the control unit 40 is notified. Then, the transmission data is compressed into a burst signal having a format corresponding to the data rate and output to the CDMA signal processing unit 6.
[0025]
The CDMA signal processing unit 6 performs a spreading process on the burst signal compressed by the voice code processing unit 7 using a PN code corresponding to the transmission channel. Then, quadrature modulation processing is performed on the processing result, and the result is output to the transmitter 5 as a quadrature modulation signal.
[0026]
The transmission unit 5 combines the quadrature modulation signal with the transmission local oscillation signal to convert it to a radio frequency signal, and based on the transmission data rate notified by the control unit 40, only the effective portion of the radio frequency signal is amplified by high frequency. And output to the antenna duplexer 2. The transmission local oscillation signal is generated by the frequency synthesizer 4 and is an oscillation signal having a frequency corresponding to the control voltage from the control unit 40.
[0027]
As for the radio frequency signal from the transmission unit 5 input to the antenna duplexer 2, only the radio frequency signal in the transmission band is output to the antenna 1 by the transmission filter 22, and is radiated into the space toward the base station. . The radio frequency signal in this transmission band is not input to the receiving unit 3 by the reception filter 21.
A power supply circuit 31 generates a predetermined operating power supply voltage Vcc based on the output of the battery 30 and supplies it to each circuit.
[0028]
The control unit 40 controls, for example, a microcomputer as a main control unit. The control contents include a normal communication control function for establishing communication with a base station (not shown) and performing communication.

The position display information setting control unit 40a performs control for creating position display information to be set in the terminal device of the communication partner, and control for transmitting and setting the created position display information to the communication partner.
[0031]
The position display information is the same position as the display data V including display contents that are easy for the user to understand (for example, “XX station”, “company”, etc.) and the reference position information R indicating the reference position. And an allowable amount A to be allowed.
[0032]
The position display information recording control means 40b performs control to record position display information associated with each communication partner in a storage unit 41 (to be described later) or to change the setting of the recorded contents.
[0033]
The position display information display control means 40c refers to the information stored in the storage unit 41 based on the caller number and the position information notified from the communication partner when receiving an incoming call, and converts and displays the position of the communication partner into easy-to-understand information. Thus, control for notifying the user of the location of the caller is performed.
[0034]
The storage unit 41 uses, for example, a semiconductor memory such as a ROM or a RAM as a storage medium. In this storage medium, the control program and control data of the control unit 40, telephone book data in which names and telephone numbers are associated, In addition to storing data related to the outgoing / incoming call history, a setting information storage area 41a and a position display information storage area 41b are provided.
[0035]
The setting information storage area 41a is a storage area for storing the position display information created by the position display information setting control means 40a.
As shown in FIG. 2, the position display information storage area 41b is a storage area for storing position display information and additional information in association with each telephone number (caller number) of the communication partner.
[0036]
The console unit 42 has a key group such as a dial key, a call key, a power key, an end key, a volume control key, and a mode designation key, and an LCD display for displaying the telephone number of the other party terminal and the operating state of the device. A sounder that can reproduce and output melody data, and an LED lamp that indicates a discharge state of the battery 30 (requires charging of the battery 30) are provided.
[0037]
Although not shown, the base station that connects this mobile radio terminal device to the network of the mobile communication system reports its own location information (latitude / longitude information) to the connected mobile station. It has a function to do.
[0038]
Next, the operation of the mobile radio terminal apparatus having the above configuration will be described.
First, an operation in the case where the position display information is set for the terminal device on the incoming side using the terminal device on the outgoing side will be described. FIG. 3 is a flowchart showing the processing performed during this operation, and this processing is performed by the position display information setting control means 40a.
[0039]
When the user operates the console unit 42 to make a request, the position display information setting control means 40a that has detected the request first detects a nearby communicable base station in step 3a, and this detected base station The position information broadcast from is received, and the process proceeds to step 3b.
[0040]
In step 3b, the position display information setting control means 40a accepts a text input of the display data V from the user and an input of an allowable amount A (unit: [second]) set in association with the user through the console unit 42.
[0041]
If necessary, image data, text data, musical score data of a ringing melody, and the like are received as additional information from the user.
Here, the allowable amount A is expressed in units of [seconds] because the position information is latitude / longitude information, but may be input in meters and converted into units of seconds.
[0042]
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 received in step 3b with the allowable amount A (addition). If there is information, it is also added.) It is recorded in the setting information storage area 41a as one position display information. Thereafter, the information is transmitted to the set terminal device of the other party, the position display information recorded in the setting information storage area 41a is transmitted, and the process ends.
[0043]
Next, a description will be given of the operation when the terminal device on the sending side transmits position display information by the processing shown in FIG. 3 as a terminal device on the receiving side. FIG. 4 is a flowchart showing processing performed during this operation, and this processing is performed by the position display information recording control means 40b.
[0044]
When the user performs an operation for responding to an incoming call from the terminal device on the transmission side by operating the console unit 42, the position display information recording control means 40b that has detected the operation first starts the terminal device on the transmission side in step 4a. The position display information is received from, and the process proceeds to step 4b.
[0045]
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 incoming call, and ends the processing. To do.
[0046]
Next, the operation in the case of newly registering / editing information recorded in the position display information recording control means 40b, which is used as a terminal device on the receiving side, will be described. FIG. 5 is a flowchart showing the processing performed during this operation, and this processing is performed by the position display information recording control means 40b.
[0047]
When the user operates the console unit 42 to make a request to start the above process, the position display information recording control means 40b that detects this first registers the new position display information to the user in step 5a. Whether to edit already registered information or not is displayed on the LCD display of the console unit 42.
[0048]
Here, when there is an instruction for new registration through the console unit 42, the process proceeds to step 5b, whereas when there is a request for editing, the process proceeds to step 5e.
[0049]
In step 5b, the position display information recording control means 40b detects a neighboring base station capable of communication, receives position information broadcast from the detected base station, and proceeds to step 5c.
[0050]
In step 5c, the position display information recording control means 40b accepts input of the telephone number of the communication partner, the allowable amount A and the display data V from the user through the console unit 42 in order to create new position display information. Migrate to Here, image data, text data, musical score data of the incoming melody, and the like are received as additional information from the user as necessary.
[0051]
In step 5d, the position display information recording control means 40b sets the position information acquired in step 5b as reference position information R, associates the information received in step 5c with this, and records it in the position display information storage area 41b. Then, the process ends.
[0052]
On the other hand, in step 5e, the position display information recording control means 40b reads out information stored in the position display information storage area 41b, displays it on the LCD display of the console unit 42, and edits from the user through the console unit 42. The designation of target position display information is accepted, and the process proceeds to step 5f.
[0053]
In step 5f, the position display information recording control means 40b displays only the position display information designated in step 5e on the LCD display of the console unit 42, receives a correction instruction from the user through the console unit 42, and step 5g. Migrate to
Here, the correction instruction includes correction of the corresponding telephone number, reference position information R, allowable amount A, display data V, and additional information.
[0054]
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 on the position display information storage area 41b. The process ends.
[0055]
Next, the operation when an incoming call occurs will be described. FIG. 6 is a flowchart showing processing performed at the time of the incoming call, and this processing is governed by the position display information display control means 40 c and the normal control function of the control unit 40.
[0056]
First, when an incoming call occurs, the position display information display control means 40c that detects the incoming call is connected to the caller ID from the connected base station and the terminal device on the caller side in step 6a. The position information notified from the base station is received, and the process proceeds to step 6b.
[0057]
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. On the other hand, if the corresponding data does not exist, the process proceeds to step 6h.
[0058]
In Step 6c, the position display information display control means 40c has the reference position information R closest to the position information received in Step 6a among the position display information associated with the caller number notified in Step 6a. An object is detected, and the process proceeds to step 6d.
[0059]
In step 6d, the position display information display control means 40c obtains the difference between the reference position information R of the position display information detected in step 6c and the position information received in step 6a.
[0060]
Then, the position display information display control unit 40c determines whether or not the difference is equal to or smaller than the allowable amount A of the position display information detected in step 6c. If the difference is equal to or smaller 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.
[0061]
In step 6e, the position display information display control means 40c displays the display data V of the position display information detected in step 6c on the LCD display of the console unit 42, and proceeds to step 6f.
[0062]
In step 6f, the position display information display control means 40c determines whether or not additional information associated with the caller number notified in step 6a exists. Here, when additional information exists, it transfers to step 6g, and when additional information does not exist, it transfers to step 6h.
[0063]
In Step 6g, the position display information display control means 40c outputs additional information associated with the caller number notified in Step 6a, and proceeds to Step 6h.
[0064]
Here, if the additional information is image data or text data, the position display information display control means 40c outputs it by displaying it on the LCD display of the console unit 42. Then, the sounder of the console unit 42 is driven and controlled, and the ringing melody is output.
[0065]
In step 6h, the control unit 40 monitors the keys of the console unit 42 to determine whether or not the user answers the incoming call. If the user performs an operation for responding to an incoming call, the process proceeds to step 6i. If an operation for responding to the incoming call is not performed, the process proceeds to step 6j.
[0066]
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 unit 40 monitors whether or not an incoming signal from the base station has arrived. If the incoming signal can be received, the process proceeds to step 6h again. On the other hand, if the incoming signal cannot be received, the process ends.
[0067]
As described above, in the mobile radio terminal apparatus having the above-described configuration, the display data V indicating the position and the reference position information R indicating the reference position of the display are displayed as the position display information in association with the telephone number of the caller. And the allowable amount A is stored. Then, among 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 the reference position information R and the notified position information are detected. When the difference from the information is equal to or smaller than the allowable value A, the display data V is displayed to notify the incoming call.
[0068]
Therefore, according to the mobile radio terminal device configured as described above, even if the location information of the caller notified from the network side is information that is difficult to understand intuitively such as latitude / longitude information, The user can convert the information into easy-to-understand position information for notification, and can easily understand and specify the position where the mobile communication terminal on the transmission side exists.
[0069]
And since the position display information is set for each caller, even if a large amount of position display information is registered, the display data can be quickly searched based on the caller number, and the position information is displayed. The time until is short.
[0070]
In addition, since the position display information to be registered on the receiving side can be created using the position information of the base station received from the base station on the receiving side as the reference position information R, latitude / longitude information that is difficult to set It can be set easily.
[0071]
Further, the position display information registered on the receiving side can be created by using the position information of the base station received from the base station on the calling side as reference position information R, and transmitted to the receiving side for setting. Therefore, it is not necessary to go to the location where the called party wants to register, and latitude / longitude information that is difficult to set can be set easily.
[0072]
Furthermore, since an allowable value A can be set for each position display information, for example, for a large station, a small allowable value A is set to distinguish the east and west exits, and there is no need to distinguish the exit. For, the allowable value A can be set relatively large, and the accuracy as position information can be increased as necessary.
[0073]
It is also possible to store additional information in association with the caller number and output the information together with the incoming call.
In addition, since the user can easily understand location information before answering an incoming call, the user on the incoming side estimates the request of the user on the outgoing side without responding to the incoming call according to the location of the caller. be able to.
[0074]
The present invention is not limited to the above embodiment.
For example, in the above embodiment, the location information notified to the receiving side is explained on the assumption that the network performs notification based on the identification information of the base station to which the terminal device on the transmitting side is connected. However, instead of this, for example, the terminal device on the transmission side may acquire its own location information from the network and transmit it to the reception side.
[0075]
Further, in the above-described embodiment, the case of an incoming call has been described. However, the present invention is not limited to the case of an incoming call, but can be applied to the case where the location information of the terminal device on the caller side is notified after communication is started. Nor. Even in this case, the same effect can be obtained.
[0076]
In the above embodiment, the case where a plurality of pieces of position display information are associated with one telephone number has been described as an example, but of course, only one piece of position display information may be associated.
[0077]
In this case, since there is only one position display information, one piece of registered information is always the closest position information. However, even if an incoming call is received from a location far from the registered information location, it is possible to prevent erroneous display by setting the allowable value A.
In addition, it goes without saying that the present invention can be similarly implemented even if various modifications are made without departing from the gist of the present invention.
[0078]
【Effect of the invention】
As described above, according to the present invention, display information and position information are stored in advance in the storage unit, and additional information is stored in association with the identification information on the transmission side and received by the receiving unit. When the difference between the location information on the transmission side and the location information stored in the storage means is equal to or less than a preset allowable value, display information and identification information are displayed on the display means and are associated with the identification information on the transmission side. Output additional information.
[0079]
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, the display information associated with the information in advance is easily displayed. Since it can be converted and displayed, and additional information can be output accordingly, it is possible to provide a mobile communication terminal capable of easily understanding and specifying the location of the mobile communication terminal on the transmission side.
[0080]
