Description

The present invention relates to a communication terminal having a communication function, in particular, a function of displaying information of a caller or a mail sender when an incoming call is received, an incoming display concealment method for a communication terminal, and an incoming display concealment program for a communication terminal.

2. Description of the Related Art In recent years, portable terminals having a wireless communication function have been popularized in accordance with the reduction in size and weight of communication terminals and the spread of wireless communication lines. A mobile phone, which is one of mobile terminals having a wireless communication function, has a data communication function in addition to a voice communication function by telephone, and transmits and receives electronic mail (hereinafter simply referred to as mail) and on the Internet. It is used for various purposes such as browsing of websites and merchandise transactions using Internet shopping.

With the development of communication technology using such mobile phones, personal information and business-related information are stored in mobile phones and the opportunities for carrying them are increasing. Among them, an address book function for storing frequently used contacts in a mobile phone in advance is a function provided in many mobile phones currently used. By using the address book function, the user of the mobile phone can easily specify a contact address. In addition, when the mobile phone receives an incoming call or mail, a so-called incoming call display function is used to display the name registered in the address book instead of displaying the caller's telephone number or the mail address of the sender. Can do. Thereby, the user of the mobile phone can easily identify who is the caller or the sender of the mail.

In addition, information such as a specific contact registered in the address book is set in advance in association with a predetermined image, and when an incoming call or mail is received from the specific caller, it is associated with the incoming call display. Display an image. A technique for allowing a user of a mobile phone to visually and intuitively recognize caller information by displaying an image is disclosed (for example, see Patent Document 1).

With the widespread use of such address book functions, leakage of information that occurs when a third party sees an incoming call displayed on the display of a mobile phone has become a problem in recent years. For example, consider a case where a mobile phone is used in a place where many people gather, such as public transportation or school, and an incoming call is displayed. If the third party can see the incoming call display, the information of the caller of the mobile phone may be leaked. In order to solve such a problem, it is recognized whether or not the mobile phone is in, for example, public transportation by monitoring the communication status of the short-range wireless chip provided in the mobile phone. And when it exists in public transport, the technique which prohibits the incoming call display of a mobile telephone is disclosed (for example, refer patent document 2).

  FIG. 3 is a block diagram illustrating an internal configuration of the mobile phone 1 according to the present embodiment.

A radio signal transmitted from a radio base station 84 to be described later is received by the antenna 21 and then input to the receiving circuit (RX) 23 via the duplexer (DUP) 22. Receiver circuit 23
The received radio signal and the local transmission signal output from the frequency synthesizer (SYN) 24 are mixed and frequency-converted (down-converted) into an intermediate frequency signal. Then, the down-converted intermediate frequency signal is demodulated by the receiving circuit 23 and output as a received baseband signal.

The reception baseband signal output from the reception circuit 23 is a CDMA (Code Div.
(Sion Multiple Access) signal processing unit 26. The CDMA signal processing unit 26 includes a Rake receiver (not shown). In this Rake receiver, a plurality of paths included in the received baseband signal are despread with each spreading code (that is, the same spreading code as the spread code of the spread received signal). Then, the signal of each path subjected to the despreading process is subjected to coherent Rake synthesis after rotating the phase. The data sequence after Rake combining is subjected to deinterleaving and channel decoding (error correction decoding), and then binary data determination is performed. As a result, the CDMA signal processing unit 26 generates received packet data in a predetermined transmission format. The received packet data is input from the CDMA signal processing unit 26 to the compression / decompression processing unit 27. The CDMA signal processing unit 26 is a DSP.
(Digital Signal Processor).

The compression / decompression processing unit 27 separates the received packet data output from the CDMA signal processing unit 26 for each media such as an audio signal and a data signal by a demultiplexing unit (not shown), and corresponds to the separated media. Each decoding process is performed.

On the other hand, the user's voice signal input to the microphone 7 is amplified to an appropriate level by the transmission amplifier 30 and then PCM-encoded by the PCM codec 28. This PCM
The encoded digital audio signal is input to the compression / decompression processing unit 27. Also,
A data signal such as a mail generated by the control unit 31 is also input to the compression / decompression processing unit 27.

The compression / decompression processing unit 27 compresses and encodes the digital audio signal output from the PCM codec 28 or the data signal output from the control unit 31 in a format corresponding to a predetermined transmission data rate. Thereafter, the compression-coded signal is multiplexed by a demultiplexer (not shown) according to a predetermined transmission format and then packetized. The transmission packet data after being packetized is output to the CDMA signal processing unit 26.

The CDMA signal processing unit 26 performs spread spectrum processing on the transmission packet data output from the compression / decompression processing unit 27 to generate a spread signal. This spread spectrum process is performed using a spread code assigned to the transmission channel. The spread signal generated by the CDMA signal processing unit 26 is output to the transmission circuit (TX) 25. The transmission circuit 25 modulates the spread signal using a digital modulation method such as a QPSK (Quadrature Phase Shift Keying) method. Further, the transmission circuit 25 synthesizes the spread signal and the local transmission signal generated from the frequency synthesizer 24, and performs frequency conversion (up-conversion) into a radio signal. Then, the transmission circuit 25 amplifies the radio signal that has been up-converted so as to satisfy the transmission power level instructed by the control unit 31. This amplified radio signal is
The signal is supplied to the antenna 21 via the antenna duplexer 22, and a radio signal is transmitted from the antenna 21 toward a radio base station 84 to be described later.

In addition, the mobile phone 1 is provided with a clock signal generator (timer) 39 that calculates a predetermined period and supplies a clock signal to the control unit 31 at each predetermined period. Further, the power supply circuit 34 provided in the cellular phone 1 supplies a predetermined operation power supply voltage Vcc generated by analog / digital conversion of the analog voltage output of the battery 9 to each circuit unit described above.

The control unit 31 includes a CPU (Central Processing Unit), a ROM
(Read Only Memory) and RAM (Random Access)
Memory). The CPU executes processing according to a program stored in the ROM or various application programs loaded in the RAM. Further, the CPU processes signals supplied from each circuit unit described above, generates various control signals, and supplies them to each circuit unit. Through these processes, the CPU comprehensively controls the mobile phone 1. The RAM stores data necessary for the CPU to execute various processes. In addition, the control unit 31 includes a video RAM (not shown), and stores information related to video displayed on the main display 10. The storage unit 32 is, for example, a flash memory element that is an electrically rewritable or erasable nonvolatile memory, or an HDD (Hard).
Disc Drive) and the like. The storage unit 32 stores various application programs and data groups that are executed by the CPU of the control unit 31. The storage unit 32 stores so-called address book data for registering a contact used by the mobile phone 1 as a contact. In the address book, for example, in addition to a telephone number, a mail address, a mail group, and a contact name associated with the contact, mark information related to the contact is stored.

(Network configuration)
FIG. 4 is a conceptual diagram showing network connection for connecting, for example, the mobile phone A (70) on the outgoing side and the mobile phone B (71) on the incoming side. The network 80 is, for example, a radio base station A
(83), B (84), a control device 85, a database server 86, an exchange device 87, and a mail server 88. In addition, the Bluetooth provided in the mobile phone B (71)
The Bluetooth radio signal is exchanged through the Bluetooth antenna 33.
The auth communication terminal 72 is also used as necessary.

The radio base stations A (83) and B (84) modulate a wired signal flowing between the networks into a wireless signal and transmit it to a mobile phone in the network 80. Further, the wireless signal transmitted from the mobile phone is demodulated into a wired signal and transmitted to the network 80.

The control device 85 holds presence information of communication terminals such as mobile phones in the network 80. Furthermore, a line route to a contact is designed according to a call instruction or a mail transmission instruction performed by a mobile phone belonging to the network 80.

The switching device 87 designs a circuit route to the signal transmission destination according to the contact address information set in the packet signal such as mail transmitted by the communication terminal of each mobile phone belonging to the network 80. Furthermore, according to the circuit route designed by the switching device 87 or the control device 85,
A so-called circuit switching process is performed for switching circuit connections between networks or switching devices.

The mail server 88 temporarily stores the transmitted mail when the mail is transmitted to each mobile phone in the network 80. Furthermore, mail data is output in response to a mail data output instruction output from the control device 85 or the communication terminal of each mobile phone.

(Call processing)
Next, processing when mobile phone A (70) makes a call to mobile phone B (71) and makes a call will be described. Here, the radio base station A (83) is used for the cellular phone (70).
) Provides a radio signal, and the radio base station B (84) provides a radio signal to the mobile phone B (71).

First, the mobile phone A (70) on the calling side makes a call request to the mobile phone B (71). The transmission request is transmitted toward the radio base station A (83) that provides a radio signal to the mobile phone A (70). When the radio base station A (83) receives the transmission request, it demodulates the received signal,
The demodulated transmission request is transmitted to the control device 85. When the control device 85 receives the call request,
From the contact address information included in the outgoing call request, it is confirmed that the contact is the mobile phone B (71). When the control device 85 confirms the contact information, the control device 85 searches for the location of the radio base station B (84) that can transmit and receive radio signals to and from the mobile phone B (71). When the location of the radio base station B (84) is confirmed, the control device 85 designs a line path connecting the radio base stations A (83) and B (84). The design of a normal line route is a protocol that sets a communication cost for each line in advance and selects a route that minimizes the total communication cost for the line route.
PF (Open Shortest Pass Fast) is used. Control device 85
Drives the switching device 87 so that communication can be performed through the designed line path, and makes the line conductive. The control device 85 notifies the mobile phone A (70), which is the transmission source, and the mobile phone B (71), which is the contact point, that the line is conductive. Thereby, the telephone call between the mobile phone A (70) and the mobile phone B (71) is started.

(Mail transmission / reception processing)
Next, processing when the cellular phone A (70) transmits packet data such as mail to the cellular phone B (71) will be described.

First, the cellular phone A (70) issues a mail transmission instruction specifying the cellular phone B (71) as a contact. The cellular phone A (70) converts the mail into radio packet data and transmits the radio packet data to the radio base station A (83). When receiving the radio packet data, the radio base station A (83) demodulates the received signal and transmits the demodulated wired packet data (hereinafter simply referred to as mail) to the control device 85. The control device 85 that has received the mail refers to the contact information of the mail and confirms that the destination is the mobile phone B (71). When recognizing the address of the mobile phone B (71), the control device 85 confirms the address of the mail server 88 that provides mail service to the mobile phone B (71). When the address confirmation of the mail server 88 is performed, the control device 85 designs a line path that connects the control device 85 and the mail server 88. In designing the circuit route, the OSPF protocol described above is usually used.

When the line route is designed, the control device 85 transmits a mail to the exchange device 87. The switching device 87 performs circuit switching processing according to the designed circuit path and sends mail to the mail server 88.
Send to. The mail server 88 stores the received mail in an information recording medium held by itself. Next, the cellular phone B (71) transmits a mail reception instruction to the control device 85. The control device 85 transfers a mail reception instruction to the mail server 88. The mail server 88 reads the stored mail in response to the mail reception instruction, and transmits the read mail to the radio base station B (84) that provides a wireless communication line to the mobile phone B (71). Radio base station B (
84) transmits the mail to the mobile phone B (71), and the mobile phone B (71) receives the mail, whereby the mail is transmitted and received.

(Secret display setting)
Next, the operation of concealing the sender information when the mobile phone B (71) receives a call or mail will be considered. When the mobile phone B (71) receives an incoming call and displays it in public transportation or outdoors, a third party can see the incoming call display, and information leakage is expected.

In order to cope with this, in the present invention, when the cellular phone B (71) is under a specific condition, the caller's information is not displayed, but instead an incoming call is displayed by a preset mark or the like.

FIG. 5 shows a screen display example on the main display 10 when an incoming call notification is performed. For example, when a call from a caller registered in the address book as “Mr. Yamada” is received, information such as the caller's name is displayed on the main display 10 and the sub-display 11 as shown in FIG. . Here, when the mobile phone B (71) is in a condition of performing confidential display, as shown in FIG. 5 (b) or FIG. 5 (c), information such as the sender is replaced with a specific mark and displayed. To do. When an operation for canceling the confidential display is input, FIG.
Switch the display to the incoming call display. Thereby, the situation where information, such as a sender | caller, leaks to a 3rd party can be prevented, and a sender | caller can be recognized by the mark displayed instead. Further, when the mobile phone B (71) moves to a place where there is no risk of information leakage, the confidential display can be canceled and the information on the destination can be recognized.

FIG. 6 shows a screen display example on the main display 10 when setting confidential display. Hereinafter, an example of the procedure for setting the confidential display will be described.

First, from the operation setting screen of the cellular phone B (71) by the input means, "Concealment display setting"
Is selected (see FIG. 6A). When “secret display setting” is selected by the input means, a confidential display setting screen is displayed (see FIG. 6B). On the secret display setting screen, for example, items of “secret user setting”, “secret display condition setting”, or “cancellation operation setting” are displayed.

Then, when “setting a concealer” is selected by the input means, a concealer setting screen is displayed (see FIG. 6C). From the address book in the storage unit 32, a sender who is to perform confidential display is selected by the input means. In addition, a mark corresponding to the caller is selected.

The selected destination telephone number and / or mail address and the confidential display mark are associated with each other and stored in the storage unit 32 as the concealer setting information. Here, the concealer setting information is stored in the storage unit 32, but a concealment display mark may be set as one of the registration information of the address book information in the storage unit 32.

Next, when “secret display condition setting” is selected by the input means, a confidential display condition setting screen is displayed (see FIG. 6D). A condition for switching the incoming call display to the secret display is set by the input means. The set secret display condition information is stored together with the secret person setting information in the storage unit 3.
2 is stored.

Examples of the confidential display condition include the following.
The first condition is a condition using time information such as a secret display between 9:00 and 21:00. By setting the confidential display condition according to the time zone when the user of the mobile phone B (71) goes out, information leakage when the mobile phone B (71) is not at home can be prevented.

The second condition is a condition using the state of power supply connection such as performing a secret display when charging. When the mobile phone B (71) is being charged, the user can use the mobile phone B (71).
) Is not in the vicinity. In such a case, it is possible to prevent information leakage by performing confidential display.

The third condition is that the Bluetooth communication terminal 72 associated with the mobile phone B (71).
This is a condition using. The user of the cellular phone B (71) wears the Bluetooth communication terminal 72 in advance. The mobile phone B (71) and the Bluetooth communication terminal 72 transmit and receive Bluetooth radio signals at predetermined time intervals. Since the Bluetooth radio signal is a weak radio signal, the cellular phone B (71
) Cannot receive Bluetooth wireless signals. When communication using a Bluetooth wireless signal is not possible, the user of the mobile phone B (71)
), The mobile phone B (71) switches the incoming call display to the secret display.

The fourth condition is that when an incoming call is received from a specific caller registered in the address book of the storage unit 32 or a caller belonging to a specific mail group, the mobile phone B (71) conceals the incoming call display. Switch to display. As a result, it is possible to prevent a situation in which information of a caller who does not want to be known is leaked.

In addition, a condition for switching to the confidential display when a specific operation is performed by the input unit, a condition for switching to the confidential display when the cellular phone B (71) is in the closed state, and the like are conceivable.

These conditions may be such that secret display is performed when all the set conditions are satisfied, or secret display may be performed when any of the set conditions is satisfied. Alternatively, a condition for performing confidential display may be newly created by arbitrarily combining the set conditions.

When “cancel operation setting” is selected by the input means, a cancel operation setting screen is displayed (see FIG. 6E). And the setting of the operation | movement which switches the sender | caller information secretly displayed by the input means to a normal incoming call display is performed. Part or all of the confidential display condition information is added or deleted from the storage unit 32 according to the setting of the release operation. Alternatively, the secret display mark set in the address book is added or deleted.

Examples of the release operation include the following.
The first release is an operation of releasing the confidential display when it is detected that the mobile phone B (71) is in the closed state and is no longer in the closed state. In this operation, FIG.
As shown in FIG. 4, the display on the sub-display 11 maintains a secret display, and the main display 10
Only the normal incoming call display may be used. Mobile phone B (71) in places where there is a risk of information leakage
Is closed, and the mobile phone B (71) is shifted to the open state in a place where the incoming call display can be safely viewed, so that the information of the caller can be confirmed. In addition, since the normal incoming call display is performed when the closed state is lost, the mobile phone B (71) is slightly opened so that the main display 10 is not visually recognized by a third party. Even when the user (71) looks into the main display 10, the information of the caller can be confirmed safely.

The second release is an operation of releasing the confidential display when a specific operation is performed by the input means. The third release is an operation of releasing the confidential display when an operation using the acceleration sensor (for example, an operation of shaking the mobile phone B (71)) is performed among the input means.

(First embodiment)
1st Embodiment shows the process which switches whether a normal incoming call display is performed according to a secret display condition set in advance, or a secret display is performed when the mobile phone B (71) receives a call or mail. ing. With this process, the incoming call display is concealed according to the setting described in the section (Secret display setting), and information leakage is prevented. Hereinafter, a processing procedure will be described using the operation flow shown in FIG.

First, the mobile phone B (71) in the standby state receives a call or mail (Yes in step 101). The control device 31 of the cellular phone B (71) determines whether or not the condition for performing the confidential display is satisfied from the confidential display condition information stored in the storage unit 32. Control device 3
1 performs normal incoming call display when this condition is not satisfied (No in step 102) (
Step 103, see the screen of FIG. 5 (a) or (f)), the process is terminated (Step 11).
2).

If the condition for performing the confidential display is satisfied, the control device 31 determines whether the sender is registered in the confidential person setting information or the confidential address book of the storage unit 32 from the received telephone number or mail address. Judgment is made (step 104). If the sender is not registered in the concealer setting information or the concealed address book (No in step 104), the control unit 31 displays a typical concealment display that does not use the mark and the sender information, for example, “incoming”. Is displayed (see step 109, the screen of FIG. 5D).

On the other hand, if the sender is registered in the concealer setting information or the concealed address book in the storage unit 32 from the received telephone number or mail address (Yes in step 104), the control device 31 further displays the concealment display mark. , It is determined whether or not a secret display mark or the like is registered for the caller (step 105). When the confidential display mark or the like is not registered (No in Step 105), the control unit 31 performs a representative confidential display without using the mark or the sender information (Step 109, the screen of FIG. 5D). See). On the other hand, when a secret display mark or the like is registered (Yes in step 105), the control unit 31 performs a secret display using the registered mark or the like (step 106, the screen of FIG. 5C). See).

(Second Embodiment)
In the second embodiment, when the mobile phone B (71) receives a call or mail, the mobile phone B (71) switches whether to perform a normal incoming call display according to a predetermined hidden display condition or whether to perform a hidden display. Further, in this embodiment, the secret display on the main display 10 is switched depending on whether the cellular phone B (71) at the time of the incoming call is folded or closed. By this processing, the user of the mobile phone B (71) can recognize the caller information by opening the mobile phone B (71) that has been received in the closed state. Hereinafter, a processing procedure will be described using the operation flow shown in FIG.

First, the mobile phone B (71) in the standby state receives a call or mail (Yes in step 201). The control device 31 of the cellular phone B (71) determines whether or not the condition for performing the confidential display is satisfied from the confidential display condition information stored in the storage unit 32. Control device 3
1 performs normal incoming call display when this condition is not satisfied (No in step 202) (
Step 203, refer to the screen of FIG. 5 (a) or (f)), and the process ends (Step 21).
6).

When the condition for performing the confidential display is satisfied, the control device 31 determines whether or not the received telephone number or mail address sender is registered in the confidential person setting information of the storage unit 32 or the confidentially set address book. (Step 204). Further, the control unit 31 refers to the secret display setting and determines whether or not a secret display mark or the like is registered for the caller (step 205).
.

When the caller is not registered in the address book (No in Step 204), or when the mark or the like is not registered in the caller (No in Step 205), the control device 31 is in the closed state of the mobile phone B (71). (Step 211). Cellular phone B (7
When 1) is in the closed state (Yes in step 211), the control unit 31 performs incoming call display using number information or the like on the main display 10 and performs secret display on the sub display 11 (
Step 212, see screen of FIG. 5 (e)).

On the other hand, when the cellular phone B (71) is in the open state (No in step 211), the control unit 31 performs representative confidential display on both the main display 10 and the sub display 11 (step 213, FIG. 5 ( see screen d)). If the secret release operation is performed by the input means while the secret display is being performed (Yes in step 214), the control unit 31 switches the display to the incoming call display using the number information or the like (step 215). The incoming call display in this case is a case where a normal incoming call display is performed on both the main display 10 and the sub display 11 (FIG. 5 (
or the sub-display 11 is hidden and the main display 10 is a normal incoming call display (see the screen of FIG. 5E). Then, when a response operation to the incoming call is performed by the input means or when the incoming call ends, the control unit 31 ends the process (step 216).

On the other hand, the received telephone number or e-mail address is registered in the concealer setting information or the concealed address book in the storage unit 32 (Yes in step 204), and a mark or the like is registered in the sender. In the case (Yes in Step 205), the control device 31 determines whether or not the cellular phone B (71) is in the closed state (Step 206). Mobile phone B (71)
Is in the closed state (Yes in Step 206), the controller 31 controls the main display 1
An incoming call display using the address book information is performed at 0, and a secret display using a mark or the like is performed on the sub display 11 (see step 207, the screen of FIG. 5B).

On the other hand, when the cellular phone B (71) is in the open state (No in Step 206), the control unit 31 performs a secret display using a mark or the like on both the main display 10 and the sub display 11 (Step 208, FIG. (See screen 5 (c)).

If the secret release operation is performed by the input means while the confidential display is performed (step 2)
09), the control unit 31 switches the display to the incoming call display using the number information in the address book (step 210). In this case, the incoming call display is performed when normal incoming call display is performed on both the main display 10 and the sub-display 11 (see the screen in FIG. 5A), or the sub-display 11 is kept secret and the main display 10 is displayed. There is a case where a normal incoming call display is used (see the screen in FIG. 5B). Then, when a response operation to the incoming call is performed by the input means or when the incoming call ends, the control unit 31 ends the process (step 216).

According to the above processing, when a mail or a call is received in a state where the condition for performing the confidential display is satisfied, the telephone number or the mail address of the caller is stored in the storage unit 32 or the confidential setting information is stored. If a mark or the like for confidential display is registered in the address book, confidential display can be performed using this. Furthermore, the mobile phone B (
71) switches the display on the main display 10 depending on whether or not it is in the closed state. Thereby, even when a third party sees the incoming call display, there is no fear of leaking the sender's information. Further, by opening the mobile phone B (71) in a place where there is no worry that the main display 10 of the mobile phone B (71) can be seen by a third party, the information of the caller can be easily confirmed.
