BACKGROUND OF THE INVENTION
The present invention relates to a mobile terminal having a telephone function, represented by a mobile phone, and a message transmission method at the time of incoming call.
[0002]
[Prior art]
In recent years, the popularization of mobile phones has been remarkable, and the frequency and importance of mobile phones have increased accordingly. As a result, the number of incoming calls increased in places and situations that could not be answered immediately.
[0003]
Also, recent telephones have an incoming call history storage function that saves incoming call history information without answering the incoming call. This incoming call history information usually includes the incoming date and time, the caller's telephone number, and information on the other party searched from the built-in telephone directory data based on the telephone number.
[0004]
[Problems to be solved by the invention]
When a call cannot be answered immediately, the user can only take one of the following options: use the answering machine function, hold the call, or reject the call. There was no way to tell if they couldn't answer the call on the spot.
[0005]
In addition, the conventional incoming call history information has not been a material for determining whether the receiver should return the phone or not.
[0006]
The present invention has been made in such a background, and an object of the present invention is to provide a mobile phone capable of transmitting a reason for not responding to a caller when the call cannot be immediately answered as a message without the caller speaking. It is to provide a terminal and a message reply method.
[0007]
Another object of the present invention is to provide a portable terminal and a message reply method that can use information that is used to determine whether or not a message should be returned immediately as display information and / or incoming call history information when an incoming call is received. It is in.
[0008]
[Means for Solving the Problems]
A portable terminal according to the present invention is a portable terminal having a telephone call function and a message data transmission function, wherein a key input means for accepting a user's key operation and a user's predetermined setting for the key input means when a call is received. And a message replying means for replying the message selected by the user or the message created by the user to the caller of the telephone after the connection is once cut according to the key operation.
[0009]
When a user performs a predetermined key operation, such as when the user receives an incoming call or is in a situation where voice cannot be answered immediately, the connection is temporarily disconnected and the message selected by the user or the user at that time or earlier The created message is returned to the caller of the telephone. As a result, the reason why the caller does not respond when the call cannot be answered immediately can be transmitted as a message without the caller speaking.
[0010]
It is preferable to provide means for storing a plurality of predetermined messages as the message options. In this case, the user can select a desired message as a transmission target from the plurality of messages.
[0011]
The message is a short message transmitted to the telephone number of the notified caller. Alternatively, in the case of having phone book data in which an e-mail address is stored in association with a telephone number, the message is an electronic message obtained by referring to the phone book data and corresponding to the notified phone number of the caller. It can be an email sent to a mail address.
[0012]
The portable terminal may further include means for displaying the simple information transmitted from the caller when making a call on the display unit when receiving a call. This display of simple information is useful for determining the degree of necessity of the message reply.
[0013]
In the case of further comprising means for displaying incoming call history information on the display unit in response to a user operation, the incoming call history information may include the simplified information.
[0014]
There may be provided means for storing a plurality of incoming call history information, and means for deleting the older incoming call history information when incoming and outgoing of the same simple information from the same caller. In this case, it is preferable not to delete the incoming call history information when the outgoing date is different even for simple information of the same content from the same sender.
[0015]
A message reply method according to the present invention is a message reply method in a portable terminal having a telephone call function and a message data transmission function, and a step of making an incoming call and making a call in response to a first key operation after the incoming call. And a step of transmitting a message in response to a second key operation after receiving an incoming call, wherein the step of transmitting the message includes a step of confirming a caller, a step of disconnecting a connection, and a message to be transmitted Determining, and transmitting the determined message to the caller.
[0016]
The method may include a step of confirming whether or not the incoming call is a caller non-notified phone. If the call is a non-notified phone, it is not known who should send the message, and the process proceeds to the step of sending the message. do not do.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0018]
FIG. 1 shows a schematic configuration of a communication system that enables communication between mobile phones as mobile terminals to which the present invention is applied. In this figure, as an example, a communication system is shown in which two mobile phones 10A and 10B are connected via a base station 2A, a control station 1, and a base station 2B. It is assumed that the communication system of this example employs a so-called wideband code division multiple access (W-CDMA) system as a mobile phone communication system. However, the present invention is not limited to the W-CDMA system and can be applied to other communication systems. Further, it is assumed that the cellular phones 10A and 10B have not only a call function but also a transmission / reception function such as an electronic mail and other various data and programs.
[0019]
The cellular phones 10A and 10B include a display unit 311, an operation input unit 206, an antenna 200, and the like, as in a general cellular phone.
[0020]
The display unit 311 includes an LCD (Liquid Crystal Display), an EL (ElectroLuminescence) panel, or the like, and can display at least characters, numbers, symbols, icons, cursors, and preferably color moving images.
[0021]

The plurality of keys 302 include a reception key 300. The operation input unit 206 also includes a dial (jog dial) 301 used for operating a cursor displayed on the display unit 311 and scrolling the screen. By operating this operation input unit 206, the user can, for example, enter a telephone number and register it, input an e-mail, input and register an e-mail address, input and register an address book, and a message described later. Various input operations can be performed, such as an operation input for creating or selecting an image, and a movement of a cursor displayed on the screen of the display unit 311.
[0022]
The antenna 200 is, for example, a diversity antenna, and is used to transmit and receive wireless signals to and from the base station 2. The antenna 200 may be a patch antenna, a microstrip antenna, an inverted F antenna, a dipole antenna, or the like.
[0023]
A detailed description of the internal circuit configuration of the cellular phones 10A and 10B will be described later. In the following description, the mobile phone 10A is a calling-side mobile phone (hereinafter referred to as an outgoing mobile terminal 10A), and the mobile phone 10B is an incoming-side mobile phone (hereinafter referred to as an incoming mobile terminal 10B). Suppose that Further, in the following description, when neither the calling mobile terminal 10A nor the incoming mobile terminal 10B is specified, it is simply expressed as the mobile terminal 10.
[0024]
The base stations 2A and 2B are radio base station apparatuses (BTS: Base Transceiver Station) that support the W-CDMA system. Each of the base stations 2A and 2B includes an antenna 3, an outdoor reception amplifier (not shown), an outdoor reception amplifier monitoring and control device, a transmission amplification unit, a wireless modulation / demodulation unit, and the like. In the case of FIG. 1, the base station 2A performs wireless communication with the originating mobile terminal 10A, and the base station 2B performs wireless communication with the terminating mobile terminal 10B. In the following description, when neither of the base stations 2A and 2B is specified, it is simply expressed as the base station 2.
[0025]
The control station 1 is a radio network controller (RNC) compatible with the W-CDMA system, and includes a control signal processing function, an O & M (Operation and Maintenance) function, a common channel demultiplexing function, an ATM (Asynchronous Transfer Mode). ) It has a switching function and a diversity handover function, etc., and performs line connection control, handover control, etc. of the wireless line. The control station 1 is connected to a subscriber-level switch, a multimedia signal processing apparatus (MPE), and a radio base station apparatus (base station). Note that FIG. 1 omits illustration of a multimedia signal processing device, a subscriber-level switch, and the like.
[0026]
In the communication system shown in FIG. 1, when the uplink connection is made in the W-CDMA system, the calling portable terminal 10A transmits connection request information to the base station 2A using a common channel. The base station 2A transmits the connection request information to the control station 1. The control station 1 that has received this connection request information establishes a control connection with the calling portable terminal 10A, and then allocates an individual channel to the calling portable terminal 10A. This individual channel assignment information is sent to the calling portable terminal 10A using the common channel. The uplink connection is established by completing the assignment of the dedicated channel. Then, the calling mobile terminal 10A transmits the call request information of the incoming call mobile terminal 10B of the other party to the control station 1 via the base station 2A using the dedicated channel.
[0027]
Upon receiving the call request information from the calling portable terminal 10A, the control station 1 performs a simultaneous call using the common channel for downlink connection, using the common channel. When the incoming mobile terminal 10B receives the simultaneous call, it returns a response to the control station 1 via the base station 2B. Upon receiving this response, the control station 1 establishes a control connection with the incoming mobile terminal 10B, and then assigns an individual channel to the incoming mobile terminal 10B. This dedicated channel assignment information is sent to the incoming mobile terminal 10B using a common channel. The downlink connection is established by completing the assignment of the dedicated channel. Then, the control station 1 transmits call information for notifying that a call is made from the calling portable terminal 10A to the receiving portable terminal 10B via the base station 2B using the dedicated channel. When receiving the call information (receiving an incoming call), the incoming mobile terminal 10B sounds a ring tone through the built-in speaker. That is, the call information is information for causing the incoming call portable terminal 10B to ring. Note that the incoming mobile terminal 10B may vibrate the built-in vibrator at the same time as or instead of the ringing tone, but in the following description, only the case of ringing the ringing tone is taken as an example.
[0028]
After the connection between the uplink and the downlink is established, the calling mobile terminal 10A and the receiving mobile terminal 10B are in a state where they can talk to each other.
[0029]
In the second embodiment to be described later, the calling mobile terminal 10A creates or selects at least the simplified information described below when making an uplink connection for making a call, and calls the simplified information as a call. A function of transmitting to the control station 1 almost simultaneously is provided. In addition, the incoming mobile terminal 10B has a function of notifying the user of simple information that has been transmitted almost simultaneously with an incoming call, and further creating or selecting a reply message as necessary to reply.
[0030]
The simple information is used by the user of one mobile terminal 10 to inform the user of the other mobile terminal 10 (call partner) the purpose of the call, the intention of the call, the importance of the content of the call, and the like. For example, information such as messages such as characters and symbols, images, and sounds. The simple information is information that can be arbitrarily generated by the user or arbitrarily selected from a plurality of different simple information. The “simple information” in the Japanese Patent Application No. 2002-9466 previously proposed by the applicant of the present application is at least arbitrary data transmitted in addition to the outgoing call, and the mobile terminal on the receiving side transmits the simplified information almost simultaneously with the incoming call. Receive and display. As a result, the receiver can confirm the contents of the simple information at the same time as the incoming call, and can use it for judging the purpose and importance of the call. This simple information is sent to the control station 1 using a common channel when an uplink connection is requested from the mobile terminal to the base station, or the control station 1 using an individual channel after establishing the uplink connection. Can be sent to.
[0031]
Character of the message of as a simple information, such as "critically ill", "urgent", "Hello", "Good morning", "not answer the phone now", and the like, "I'll let you know later." Note that these messages can also be called subjects.
[0032]
In addition, the sound of as a simple information, as an example, "critically ill" in the same way as a text message, "emergency", "Hello", "Good morning", "not answer the phone now", "I'll let you know later", etc. Sounds that are pronounced, alarm sounds that alert people, music and environmental sounds that soften people's hearts, and so on.
[0033]
The simple information may be any one of the above-mentioned character and symbol messages, images, and sound information, or may be arbitrarily combined with them. The response message assumes text composed of characters and symbols, but is not necessarily limited to text. For example, an image or the like may be included.
[0034]
The simple information transmitted at the time of calling and the message transmitted at the time of reply are created by the user of the portable terminal 10 by operating the key 302 or the dial 301 on the operation input unit 206, for example, or Any one arbitrarily selected from a plurality of information prepared in advance in an internal memory (for example, ROM 208 or recording unit 209 described later) as a storage unit of the mobile terminal 10 may be used.
[0035]
For example, when simple information of a text message is created, the mobile terminal 10 displays a new screen for creating simple information on the screen of the display unit 311. In this state, the operation input unit 206 is operated by the user to input alphabetic characters, kana characters, numbers, and the like, and when an instruction input for kana-kanji conversion is performed as necessary, the mobile terminal 10 Simple information corresponding to the input operation is generated.
[0036]
The simple information prepared in advance is information prepared and registered in advance by the user, or information registered at the time of manufacture or shipment of the mobile terminal 10 or a service for providing simple information. Information acquired from a site on the Internet, information input from an external input terminal (not shown) provided in the mobile terminal 10, and the like. The external input terminal may be a memory slot for external memory. In this case, the simple information prepared in advance is stored in the external memory, and is read into the mobile terminal 10 from the external memory via the memory slot. The response message is the same as the simple information.
[0037]
FIG. 2 shows an internal configuration of the mobile terminal 10 according to the present invention.
[0038]
In the mobile terminal 10 shown in FIG. 2, the microphone 221 converts a user's call voice or the like into an electrical signal (that is, an analog voice signal). The analog voice signal of the call voice is amplified by an amplifier (not shown) and then input to a DSP (Digital Signal Processor) 204.
[0039]
At this time, the DSP 204 A / D (Analog / Digital) converts the analog audio signal at a predetermined sampling rate. The DSP 204 adds a CRC (Cyclic Redundancy Check) code for each transport block (TB) to the digital audio data obtained by the A / D conversion, and performs channel coding (that is, error correction coding). And interleave processing. The transport block is a basic unit of data that is processed by the physical layer (a unit in which data is transferred from the MAC (Medium Access Control) layer to the physical layer). Further, the DSP 204 adds data overhead to the bit sequence after the interleaving process after adding overhead such as pilot bits for channel estimation. The DSP 204 spreads in-phase and quadrature components on the phase plane subjected to data modulation mapping, respectively, using two layers of spreading code sequences. The DSP 204 limits the band of the spread chip data series to a predetermined band (5 MHz) with a raised cosine root Nyquist filter, and then converts the chip data series into an analog signal by D / A (Digital / Analog) conversion. The analog signal obtained by the D / A conversion is sent from the DSP 204 to the transmission unit 203.
[0040]
The transmission unit (TX) 203 performs quadrature modulation on the analog signal from the DSP 204 and further frequency-converts the quadrature modulated intermediate frequency signal into a high frequency signal (2 GHz band RF signal). Then, the transmission unit 203 amplifies the high-frequency signal and sends the amplified high-frequency signal to the duplexer 201 as a transmission signal.
[0041]
The duplexer 201 is an antenna duplexer. That is, the duplexer 201 shares one antenna 200 for the transmission signal and the reception signal, sends the reception signal from the antenna 200 to the reception unit (RX) 202, and transmits the transmission signal from the transmission unit 203 to the antenna 200. It is constituted by a filter circuit having a sending function.
[0042]
The receiving unit 202 amplifies the high frequency received signal supplied via the antenna 200 and the duplexer 201, converts the frequency of the high frequency received signal into an intermediate frequency signal, and further linearly amplifies the signal by automatic gain control. And output. The signal output from the receiving unit 202 is input to the DSP 204.
[0043]
At this time, the DSP 204 performs quadrature detection on the signal from the receiving unit 202, and A / D converts the in-phase and quadrature component analog signals obtained by the quadrature detection at a predetermined sampling rate. The DSP 204 uses the square cosine root Nyquist filter to band-limit the in-phase and quadrature components converted into digital values by the A / D conversion, and then despreads them using the same spreading code as the spreading code of the received signal. Time separation is performed into a plurality of multipath components having different delay times. Further, the DSP 204 performs coherent rake combining of the data of each of the paths separated by time, and performs binary interleaving and channel decoding (that is, error correction decoding) on the data sequence after the rake combining. The data series transmitted from the counterpart terminal is reproduced. Then, the DSP 204 discriminates the reproduced data series into audio data and other communication data.
[0044]
The audio data is D / A converted by the DSP 204, further amplified by an amplifier (not shown), and then sent to the speaker 212. The speaker 212 is driven by the amplified analog audio signal. As a result, the call voice from the call partner terminal is emitted from the speaker 212.
[0045]
The DSP 204 analyzes what kind of data the communication data is, and performs processing according to the analysis result. For example, when the communication data is text data, the DSP 204 sends the text data to the control unit 205. At this time, the control unit 205 displays the text data on the display unit 311. Further, for example, when the communication data is compressed image data, the DSP 204 decompresses the compressed image data and sends it to the control unit 205. At this time, the control unit 205 displays the image data on the display unit 311. Further, for example, when the communication data is compressed audio data, the DSP 204 expands the compressed audio data and outputs it to the speaker 213 or 212. That is, when the simple information is text data such as characters or image data, the message or image is displayed on the screen of the display unit 311. When the simple information is sound data, the sound is transmitted from the speaker. 213 or 212 is output.
[0046]
In addition, when the DSP 204 detects the call information, the DSP 204 generates a ring tone signal in response to the detection of the call information. The ring tone signal is amplified by an amplifier (not shown) and then sent to the speaker 213. The speaker 213 is driven by the amplified ringing tone signal. As a result, a ring tone corresponding to the call information is emitted from the speaker 213.
[0047]
The recording unit 209 includes a rewritable memory that does not require a memory holding operation such as a flash memory. The recording unit 209 records a telephone number, an e-mail address, an address book, the simplified information, a response message, and the like registered by the user. The recording unit 209 is also used for recording a value that can be arbitrarily set by the user among various setting values of the mobile terminal. In addition, the recording unit 209 can record various data as necessary, such as data such as transmitted / received e-mail, image data, and audio data.
[0048]
A ROM (Read Only Memory) 208 is a control program for the control unit 205 to control each unit, a simple information processing program for performing various signal processing when handling simple information and response messages, various initial setting values, Font data etc. are stored. The ROM 208 may be a rewritable ROM such as an EEPROM (Electrically Erasable and Programmable Read Only Memory).
[0049]
A RAM (Random Access Memory) 207 stores data as needed as a work area or a temporary storage area when the control unit 205 performs various data processing.
[0050]
The control unit 205 controls the operation of each unit based on a control program stored in the ROM 208 and performs various arithmetic processes. Further, the control unit 205 creates or selects simple information (or a response message) according to an input operation from the operation input unit 206, transmits / receives simple information, and displays the simple information display unit 311 based on the simple information processing program. Various processes such as control of display and output to the speaker 213, recording and reproduction to the RAM 207, the recording unit 209, and the like.
[0051]
Now, the operation of the first embodiment of the present invention in the configuration of the system and the portable terminal as described above will be described with reference to a flowchart.
[0052]
FIG. 3 shows an example of a processing flow in the present embodiment.
[0053]
This process is started when the portable terminal is turned on. When the mobile terminal is turned off, the process ends unconditionally.
[0054]
Whether or not the receiver receives the call when the mobile terminal receives an incoming call (S101, Yes) depends on whether or not a predetermined key is operated. The predetermined key is, for example, the reception key 300. When an any key answer function that is equivalent to receiving an incoming call (being in an off-hook state) when any key other than the receiving key 300 is pressed is attached, the function is OFF. It is assumed that. When the reception key 300 is pressed, the mobile phone enters an off-hook state and shifts to a call (S103). The call is continued until the call ends (S104). When the call ends, the process returns to the first step S101.
[0055]
When the reception key 300 is not pressed, the presence / absence of a specific key operation is checked (S105). The specific key operation is, for example, a long press of the jog dial 301. However, the present invention is not limited to this. Even if the any key answer function is on, if there is a key that is not subject to any key answer, the key can be used for a specific key operation in step S105.
[0056]
When a specific key operation is performed (S105, Yes), it is determined whether the incoming call is a non-notified phone (S106). An unannounced phone call is a call in which the caller refuses to notify the receiver of his / her phone number and the phone number is not notified to the receiver. If it is determined that the telephone is a non-notification telephone (S106, Yes), the process returns to step S102. This is because in the case of a non-notified phone, the person to whom the reply message should be returned is unknown.
[0057]
If it is determined that the reply message cannot be replied once from step S105 to S106 (S106, Yes) and the process returns to step 102, the specific key operation in step 105 is invalidated (not accepted). Also good. Moreover, you may perform some display which tells a user that it cannot reply.
[0058]
In addition to non-notification determination, it may be determined in step S106 whether the telephone number is compatible with the short message service. The “short message service” in the present invention is a service that can normally send and receive a message with a relatively short number of characters between mobile telephones between common carriers using a telephone number as destination information. The e-mail is different from the short message in that the e-mail address is used as destination information regardless of the communication carrier and not limited to the mobile phone. If it is not compatible with the short message service, Yes in S106. Whether or not it corresponds is to determine from the telephone number whether or not the calling terminal can use the same service as the short message service that can be used by the terminal that received the call. A service correspondence table of telephone numbers may be stored in the recording unit 209 and the ROM 208.
[0059]
If the answer is YES in step S106, the process may return to step S101 after waiting for an incoming call instead of returning to step S102.
[0060]
In step S107, the telephone (connection) is disconnected. However, the telephone call may be disconnected before the message is transmitted in step S109, so that it may be disconnected when the reply message is selected in step S108 or immediately before it is transmitted in step S109. Good.
[0061]
Since a response message is transmitted after the telephone call is disconnected in step S107, a voice message to that effect may be played before the telephone call is disconnected. For example, "I can't answer the phone right now. I will send you a message." When playing the audio, the phone call may be disconnected after all the audio has been played. Or you may cut according to the above-mentioned selection (S108) or transmission (S109).
[0062]
After step S107, the process proceeds to step S108 for selecting a reply message. A response message selection screen as shown in FIG. 4 is displayed in step S108. The user selects a response message created and registered in advance on the response message selection screen. On the response message selection screen, the selection may be made by selecting (rotating the jog) with the jog dial 301 and pressing the jog dial 301. The determination may be made by pressing the key 302 corresponding to the number assigned to the reply message. Further, when an operation of another function is assigned to the jog dial or the like, it is canceled by the key operation in step S105. In the example in the figure, “Train”, “I will come later”, and “Meeting” are given as examples, but the actual response message may be the same string or longer than this. It may be a character string.
[0063]
In step S108, the response message may be automatically selected by setting in advance, or may be created in step S108. You may select whether to transmit the selected information automatically next time. When this automatic transmission is performed, a time restriction may be imposed (that is, the automatic transmission function is canceled after a predetermined time elapses). Alternatively, when the options are displayed, the options may be arranged according to the selection history of the options (for example, in order of frequency).
[0064]
After selecting the reply message in step S108, the process moves to step S109. Then, a short message is transmitted with the reply message selected in step S108 as the text and the other party's telephone number as the destination. After transmitting in step S109, the process returns to step S101 and waits for an incoming call.
[0065]
In the above description, a short message is described as an example of the message. However, instead of replying to a short message, the message may be returned by electronic mail (e-mail) in step S109. In this case, the telephone number (address book) stored in the recording unit 209 is searched using the telephone number of the other party, and the electronic mail address of the other party is confirmed. In step S109, the information selected in S108 is put into the text or subject, or both the text and subject, and an e-mail is transmitted to the confirmed address. In step S108, both text information and subject information may be selected, and information such as “phone hold” may be automatically entered for the subject. Of course, the text may be automatic or created.
[0066]
In the non-notification determination in step S106, when the e-mail address is searched and the address cannot be confirmed, the process may return to step S102.
[0067]
When a plurality of e-mail addresses are retrieved and output, an e-mail may be sent to all, or an e-mail address of a specific terminal (for example, a mobile phone) may be determined from the domain name and sent to it.
[0068]
Both the form using a short message and the form using an electronic mail are not always available as messages. However, it is a common prerequisite that the telephone number is notified. In addition to this, in the case of a short message, it is necessary that the calling side and the called side correspond to the same short message service. In the case of e-mail, it is necessary to search the e-mail address from the telephone directory.
[0069]
In this mode, in addition to the determination of non notification in step S106, it is determined whether or not the same service is supported. If it is found, search the e-mail address, and if found, send a reply message by e-mail. If neither is available, the process returns to step S102.
[0070]
Contrary to the above, the order of the e-mail address may be searched and the service determination of the short message may be performed when the corresponding e-mail address cannot be confirmed.
[0071]
Next, a method for displaying the subject including the subject in the incoming call history and a method for displaying the subject at the time of the incoming call will be described.
[0072]
In the conventional incoming call history, as shown in FIG. 5, the date and time, the telephone number of the other party, and the name of the other party obtained by searching for the address from the telephone number (XX mobile in the example in the figure) are displayed. When the incoming call is not answered or when there is an incoming call, when the incoming call history as shown in FIG. 5 is confirmed, the above-mentioned information (date / time, telephone number, name of the other party) Must be done on the basis of
[0073]
Therefore, in the present embodiment, as described above, when the simple information is transmitted simultaneously with the outgoing call, the simple information is displayed together with the incoming call history.
[0074]
FIG. 6 shows incoming call history update processing corresponding to simple information acquisition. This processing flow includes a function for suppressing the holding of duplicate information when the call history of the same simple information from the same telephone number is held. By incorporating this function, the memory can be effectively used.
[0075]
Hereinafter, the flow of FIG. 6 will be described in detail. The processing in FIG. 6 can be used in combination with the processing in FIG. 3, but can be employed independently of the message reply function in FIG. 3.
[0076]
The process of FIG. 6 is activated every time there is an incoming call. First, after starting, it is determined whether or not simple information is received (S201). If simple information has been received, the process moves to step S202. In step S202, the simplified information is acquired and temporarily stored in the RAM.
[0077]
When the simplified information is not received in step S201 and after the processing in step S202, it is determined in step S203 whether or not the incoming call is a non-notified phone. If it is determined as a non-notification telephone, the acquired information (held in the RAM) and non-notification are displayed (S204). Acquired information is information acquired in step S203. When there is no acquisition information, only non notification is displayed.
[0078]
If it is not a non-notified telephone, it is determined in step S205 whether the notified telephone number is registered in the address. If registered, the process moves to step S206, and the registered name is acquired (temporarily stored in the RAM).
[0079]
If No in step S205 or after the name is acquired in step S206, the acquired information (stored in the RAM) and the telephone number are displayed in step S207. The acquired information here is information acquired in steps S202 and S206. When there is no acquisition information, only the notified number is displayed.
[0080]
After one of the displays in step S204 or S207, the process moves to step S208. In step S208, the end of the incoming call is awaited. Termination of an incoming call includes a transition to a call. During the incoming call, the display screens in steps S204 and S207 are continued.
[0081]
When the incoming call is completed, it is determined whether or not simple information is received in step S209. If it has been received, it is determined in step S210 whether or not simple information is set to remain in the history. If No in step S209 or No in step S210, the incoming call history is updated (1) in step S212.
[0082]
If Yes in step S210, the incoming call history is searched in step S211. When the incoming call history of the same telephone number is searched, it is confirmed whether the simple information is the same. If the simple information is not the same, the incoming call history is updated (2) in step S213. If they are the same, the incoming call history is updated (3) in step S214.
[0083]
Examples of the determination criteria in step S210 include the capacity of simple information, whether simple information is text information, information obtained from a telephone number, and the like.
[0084]
In the incoming call history update (1) in step S212, the first (newest meaning) history is moved second, the second is moved third, and so on. When the number of incoming call history saved reaches the maximum, the last (oldest) incoming call history is deleted. First, this incoming call is left as a history. In the incoming call history, for example, the date / time, the call / absence, the telephone number of the other party (the non-notified telephone in the case of non-notification), information obtained from the telephone number, and the like are displayed.
[0085]
In the history update process (2) in step S213, basically the same process as in step S212 is performed, but the simple information acquired in the incoming call history is also displayed.
[0086]
In the history update process (3) of step S214, the history of the same simple information (same information) with the same telephone number is first, and the history of the same information is moved one by one. For example, if there is the same information in the third, the first is the second, the second is the third, and the third is the first (the old third information is deleted). When the same information is moved first, the incoming date and time may be updated, or both the previous incoming time and the current incoming date and time may be posted. By displaying together the number of times such as “× 2”, the number of incoming calls may be notified.
[0087]
After Steps S212, S213, and S214, this process ends.
[0088]
A display example of the incoming call history in the present embodiment is shown in FIG. As described above, by adding the simple information transmitted by the other party to the information of the incoming call history (date and time, the other party, the telephone number), it becomes possible to help the user decide whether or not to return the call.
[0089]
When there is a plurality of incoming calls from one party when there is no answer to the incoming call or when there is no call, and the incoming call history is updated sequentially as shown in FIGS. 7 and 8, it is very useful for judgment when returning the call. The subject content in FIG. 7 is “Immediate! XX case”, whereas the subject content in FIG. 8 is “XX case resolution”. Therefore, even if the former incoming call cannot be answered for some reason, or even if the incoming call itself cannot be recognized, the problem of the concern is determined from the contents of the subject of the latter incoming call without returning the call. It is understood that has been solved.
[0090]
If there are a large number of incoming calls during non-response or absence, important incoming call history may be automatically deleted without checking the contents. On the other hand, when leaving the subject in the incoming call history, if there is an incoming call with the same subject content from the same party, only the latest incoming call history is kept and the old incoming call history is deleted, so that the incoming call history memory (for example, The storage area in the RAM 207 or the recording unit 209) can be effectively used. As shown in FIG. 7 and FIG. 8, even if the incoming call is from the same party, if the subject contents are different, both are left in the incoming call history and both can be displayed. However, if the subject content of FIG. 8 is the same as that of FIG. 7, the incoming call history of the older one (FIG. 7) is deleted. However, there is a case where the meaning of an incoming call with the same subject content from the same party that has been changed (for example, one day later) changes. For example, if the subject is “Matter of today's meeting”, “Today” will be a different date one day later. In order to cope with such a case, the handling of the incoming call history may be changed by incorporating the concept of time difference. For example, when the date of both incoming calls changes or even when there is a time difference of more than a predetermined time (for example, 12 hours) even under the same conditions, the older one is not deleted.
[0091]
As shown in FIG. 9, a display similar to the incoming call history may be used for the outgoing call history of the caller mobile terminal. As a result, it is possible to effectively use the memory of the transmission history in the terminal on the transmission side.
[0092]
Similarly, when a subject is an image, it may be displayed as an incoming call history. The image may be displayed directly, or an image file name may be displayed as 000.jpg, and the image may be displayed according to the selection (designation) of the file name.
[0093]
Next, a description will be given of a display method at the time of incoming call of the receiving terminal when the simple information is transmitted simultaneously with the outgoing call using the method disclosed in Japanese Patent Application No. 2002-9466. The following description is not limited to the above-mentioned prior application, but can be applied when simple information can be received simultaneously with an incoming call.
[0094]
When displaying simple information at the time of incoming call, when displaying simple information on a relatively small display unit provided separately from the main display unit, so-called sub liquid crystal, Caller information including the caller's phone number and There is a possibility that the entire simple information cannot be displayed at the same time. In such a case, as shown in FIG. 10 and FIG. Caller information and Simple information And By displaying alternately, both displays can be recognized. Alternatively, the display may be scrolled, or only the subject content may be displayed.
[0095]
When the display unit has a size sufficient to display including the subject, the entire simplified information is simultaneously displayed as shown in FIG. When the subject is an image, display as shown in FIG. 13 is possible. In this example, the subject display area 312 is set at the bottom of the screen, but may be set at other positions such as the top and middle. Moreover, even if the size of the display area is large enough to display the subject, the first portion and the second portion may be alternately displayed as described above.
[0096]
As shown in FIG. 14, a subject display area 314 for displaying a subject at the time of an incoming call may overlap the display area for the name of the other party over almost the entire screen. In particular, this use can be considered when the subject is an image.
[0097]
The preferred embodiment of the present invention has been described above, but various modifications and changes can be made. For example, in any of the above cases, if there is color information, simple information can be displayed taking it into account. In addition, information that conveys urgency such as urgent or urgent may be provided with a function that recognizes such words on the terminal side and automatically changes the color of the character or changes the font to perform highlighting. Good.
[0098]
Regarding the incoming call history and outgoing call history, the history may be left only for the other party registered in the phone book in the terminal. Further, when the subject is an image, a large memory capacity is used, so that the image subject may not be left in the history.
[0099]
【The invention's effect】
According to the present invention, when an incoming call to the mobile terminal cannot be immediately answered, the user can tell the caller as a message why he / she cannot answer the call without making any speech.
[0100]
In addition, it is possible to prevent useless message reply processing from being activated by determining non-notification of an incoming call, or to prevent useless message transmission by performing service adaptation determination of a short message. If the phone book data built in the portable terminal is used, it is possible to confirm the electronic mail address corresponding to the caller telephone number and transmit the message by electronic mail.
[0101]
When it has a function to display the simple information transmitted from the caller at the time of incoming call on the display unit when receiving an incoming call, the simplified information received at the time of incoming call is added to the display at the time of incoming call and / or the incoming call history. It is possible to determine whether a response is required for an incoming call. Further, by deleting old information for the same simple information from the same partner, it is possible to save the storage capacity for storing history information.
