By the way, unless an incoming call is rejected or the power is turned off, an incoming call to a mobile phone can occur anytime and anywhere.

When there is an incoming call to the mobile phone as described above, the user considers various factors and receives the incoming call (that is, answers the call) or holds the incoming call.
Alternatively, it is necessary to decide whether to hang up (that is, whether to end the call without answering the call). The various factors mentioned above are
Whether the current time zone is the time zone in which the user can answer the call, the place where the user is, or the place where the user can answer the call, or the current situation in which the user is present is the situation in which the user can answer the telephone. And so on.

In addition, the user receives an incoming call to the mobile phone.
In some cases, it may be decided whether to receive the incoming call, hold it, or disconnect it by judging or guessing from whom it is. That is, for example, even if the factors of the above time zone, place, and situation are such that it is difficult to receive the incoming call, if the incoming call to the mobile phone is from an important person, the user receives the incoming call. Will be tried. Therefore, the user judges or guesses who the incoming call is from based on the limited information obtained when the incoming call is received, and decides whether to accept the incoming call, hold it, or disconnect it. There is. The information obtained at the time of the incoming call is, for example, information displayed on the built-in display by the mobile phone in response to a call request and paging. The information displayed on the display by the mobile phone is, for example, the telephone number of the other party or the name registered in the internal memory of the mobile telephone (that is, the registered telephone number depending on the other party's telephone number. The name etc. read out) and the non-notification designation message when the telephone number of the other party is non-notified.

[0006]

However, the information obtained at the time of the above incoming call is only the non-notification designation message such as the telephone number of the other party, the registered name, etc., and the amount of information is very small. Therefore, it is difficult for the user to appropriately determine whether to receive the call, hold it, or disconnect the call from only the information.

On the other hand, it is expected that mobile phones will become more popular in the future, and the frequency and importance of their use will increase.

[0008] Therefore, in the future, when the user decides whether to receive, hold, or disconnect the incoming call to the mobile phone, it is necessary to take some measures so that the user can make a more appropriate and accurate judgment. It is considered to be.

The present invention has been made in view of the above problems, and when a user decides whether to receive an incoming call to an information communication terminal such as a mobile phone, hold it, or disconnect it, An object of the present invention is to provide a communication device and a communication system that enable appropriate and accurate judgment.

[Uplink and downlink connection] FIG. 1
In the communication system shown in (1), the originating mobile terminal 10A uses the common channel to transmit the connection request information to the base station 2A at the time of the uplink connection in the W-CDMA system. 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 originating mobile terminal 10A, and then allocates an individual channel to the originating mobile terminal 10A. The information on the allocation of the individual channels is sent to the originating mobile terminal 10A using the common channel. The uplink connection is established by the completion of this dedicated channel allocation. Then, the originating mobile terminal 10A transmits the call request information of the terminating mobile terminal 10B of the other party to the control station 1 via the base station 2A, using the individual channel.

Upon receiving the call request information from the originating mobile terminal 10A, the control station 1 uses the common channel for downlink connection and makes a simultaneous call to the incoming mobile terminal 10B. When receiving the simultaneous call, the incoming mobile terminal 10B returns a response to the control station 1 via the base station 2B. The control station 1, which receives this response,
After establishing a control connection with the incoming mobile terminal 10B, an individual channel is assigned to the incoming mobile terminal 10B. This individual channel allocation information is sent to the incoming mobile terminal 10B using the common channel. The downlink connection is established when the allocation of the dedicated channel is completed. Then, the control station 1 transmits calling information for notifying that a call is made from the originating portable terminal 10A to the terminating portable terminal 10B via the base station 2B, using the dedicated channel. Incoming mobile terminal 10B
Receives the above call information (receives an incoming call),
Ring tone is played by the built-in speaker. That is, the call information is information for causing the incoming mobile terminal 10B to make a ring tone. The incoming mobile terminal 10B
May vibrate the built-in vibrator at the same time as or instead of the ring tone, but in the following description, only the case of ringing the ring tone is taken as an example.

After the uplink and downlink connections are established, the originating mobile terminal 10A and the terminating mobile terminal 10B are
You can talk to each other.

[Explanation of Simple Information] Here, the originating portable terminal 10A creates or selects at least the following simple information at the time of connecting the uplink for making a call,
It has a function of transmitting the simple information to the control station 1 almost at the same time as the call is made. Further, the incoming mobile terminal 10B has at least a function of notifying the user of the simple information transmitted almost at the same time as the incoming call, and further creating or selecting the simple information as necessary and returning it. Then, the control station 1 has a function of transferring the simple information transmitted by the transmitting portable terminal 10A to the receiving portable terminal 10B, and transferring the simple information returned by the receiving portable terminal 10B to the transmitting portable terminal 10A as necessary. I have it.

The simple information means that the user of the mobile terminal 10 on one side informs the user of the mobile terminal 10 on the other side (call partner) of the purpose of the call, the intention of the call, the importance of the call content, and the like. This is information used for that purpose, and is, for example, information such as messages such as characters and symbols, images, sounds, and the like. The simple information is information that the user can arbitrarily generate or can arbitrarily select from a plurality of different simple information. Further, the simple information is information that is transmitted and received at substantially the same time as a call and an incoming call for a call, and is different from an e-mail and other data that is transmitted and received regardless of the call and the incoming call. .

The character of the message as the above simple information is "critically ill", "urgent", "Hello", "Good morning", "is now not answer the phone", "I'll let you know later."
And so on. The message of these characters can also be called a subject.

The above-mentioned "critical" message is used, for example, when the user of the originating portable terminal 10A tries to inform the user of the incoming portable terminal 10B by telephone of the critical condition of a person. The above-mentioned “urgent” message is used, for example, when the user of the originating mobile terminal 10A tries to notify the user of the terminating mobile terminal 10B of some urgent requirement by telephone. Further, these “critical” and “urgent” messages have high importance, as indicated by the meaning of the words themselves.

The message of "Hello", "Good morning" is, for example, a user of the originating mobile terminal 10A is used, such as when you want to greet about phone and user of the incoming mobile terminal 10B. These message "Hello", "Good morning" is, for example, a user of the incoming mobile terminal 10B which receives the incoming call from the originating mobile terminal 10A, used, for example, when returning greeting to the user of the incoming mobile terminal 10B Sometimes it is. In addition, these "Hello", the message of "Good morning" is, as can be seen considering the meaning of the word itself, the "critically ill" and "emergency"
Will be less important than.

On the other hand, the message "I cannot answer the phone" or "I will contact you later" indicates that the user of the incoming mobile terminal 10B who has received the incoming call from the outgoing mobile terminal 10A cannot talk. Is used to notify the user of the originating mobile terminal 10A.

The symbol as the message of the simple information is, for example, "!" To indicate that it is urgent and of high importance.
The symbol “?” And the symbol “?” Can be considered to indicate that the degree of importance is low. Further, the degree of importance may be expressed by a certain number of symbols, for example, the number of symbols of star (*). In addition, the symbol as a message of simple information is, for example, a symbol of a musical note (♪) when making a call about music, and a man of “♂” or “♀” when making a call about a boyfriend or her topic. ), A symbol representing a woman (female), and a symbol representing the currency of “¥ $” when making a call regarding money.

Further, the image as the simple information may be, for example, an image of a facial portrait of the user, an image of the place where the user is, an image of a place related to the content of the call, or the like.
The importance when an image is used as the simple information can be set such that the image of an angry face is "large" and the image of a laughed face is "small", for example.

[0038] 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", "later Contact It may be a voice that pronounces "Suru" or the like, an alarm sound that calls attention to people, music that softens people's hearts, and environmental sounds.

It should be noted that the simple information may be any one of the above-mentioned character and symbol message, image and sound information, or any combination thereof.
The simple information such as “critical”, “urgent”, “!”, Face image, etc. is an example, and the present invention is not limited thereto.

[Generation or Selection of Simplified Information] The user of the portable terminal 10 operates, for example, the key 47, the dial 46 or the like on the operation input unit 44 for the simplified information transmitted / received at the time of making or receiving a call. Created by the above, or the internal memory of the mobile terminal 10 (for example, the recording unit 27 described later)
Any of a plurality of pieces of simple information prepared in advance may be used.

For example, when the simple information of the text message is created, the mobile terminal 10 displays the screen for newly creating the simple information on the screen of the display unit 41. Then, in this state, when the user operates the operation input unit 44 to input alphabetic characters, kana characters, numbers, etc., and further, if necessary, an instruction input for kana-kanji conversion is performed, the mobile terminal 10 will Generate simple information according to the input operation.

The simple information prepared in advance is:
Information created and registered by the user in advance, information registered at the time of manufacturing or shipping of the mobile terminal 10, information acquired from a site on the Internet that provides a simple information providing service, mobile terminal The information is information input from an external input terminal provided in 10. 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 from the external memory into the mobile terminal 10 through the memory slot.

FIG. 2 shows an example of a user interface when the user selects desired simple information from the plurality of prepared simple information. In the example of FIG. 2, a character message is given as the simple information.

In the example of FIG. 2, the portable terminal 10 is
A plurality of simple information candidates are displayed on the screen of the display unit 41. At the same time, the mobile terminal 10 also displays the cursor 42 on the screen. The mobile terminal 10 has a predetermined key 47 provided on the operation input unit 44, for example.
The cursor 42 is moved in the vertical direction indicated by an arrow 45 in the figure in response to an operation of the or jog dial 46 or the like. Further, the mobile terminal 10 displays the simple information pointed by the cursor 42, for example, in reverse video or in a color different from other simple information. This allows the user to
It can be known that the simple information on the cursor 42 can be selected. Then, when the user operates the operation input unit 44 to move the cursor 42 onto the desired simple information and then gives an instruction to select the desired simple information,
The mobile terminal 10 determines the selected simple information as the simple information to be transmitted to the mobile terminal of the other party.

The simple information candidates displayed on the screen of FIG. 2 can be arbitrarily edited by the user, such as addition, deletion, change, and change of the order of the candidates. Further, the arrangement order of the simple information candidates displayed on the screen of the display unit 41 may be automatically changed according to the selection frequency (frequency of use) of the user, for example. In this case, for example, if the simple information having a high selection frequency is placed in the order of arrangement, the user can easily select the simple information at the next selection. The simple information candidates displayed on the screen are, for example, the call area (place, address, etc.) in which the mobile terminal 10 is located.
Alternatively, it may be based on the current time. Mobile terminal 10
As a candidate for the above-mentioned simple information when, for example, is located near a theater, a message such as "the start time is near" or "change of waiting time" can be considered. Further, as one of the items displayed on the screen of the display unit 41, for example, an item of "new creation" may be provided. When the user selects this "new creation" item, the mobile terminal 10 displays a screen for new creation of simple information on the display unit 41 to enable the user to create simple information. Of course, this is just an example,
The screen for new creation of simple information can be displayed before the screen of FIG. 2 is displayed, or the screen for new creation is displayed when no candidate is selected from the candidates of simple information of FIG. It may be done. Furthermore, each simple information candidate displayed on the screen may be displayed in the form of an icon or the like that symbolizes each simple information.

In addition, it is possible to newly register the simple information transmitted to the desired call partner or the simple information sent from the call partner as it is in the internal memory.
It is also possible to register the telephone number or e-mail address of the mobile terminal of the called party, the name or address of the called party user, the company name, or the group name in association with each other. In this way, by making it possible to register the transmitted and received simple information, the user does not need to newly create the simple information.

[Transmission of Simple Information at Uplink Connection] The transmitting mobile terminal 10A uses the common channel when requesting the uplink connection for the simple information created or selected as described above. Or to the control station 1 using a dedicated channel after establishing the uplink connection.

Here, when the uplink is connected, the common channel used for transmitting the simple information is
As an example, a random access channel (RACH: Rand)
om Access Channel). This RA
The CH is a common channel in the uplink and is a channel used for transmitting control information and user data. The originating mobile terminal 10A transmits the simple information to the control station 1 as one of the user data in the RACH.

On the other hand, the dedicated channel at the time of the uplink connection is a bidirectional channel which is individually assigned to the originating mobile terminal 10A after the link connection is established, and is used for the transmission of the call request information, the call and the transmission / reception of user data. This is the channel used. When transmitting the simple information using this individual channel, the originating portable terminal 10A sends the simple information to the control station 1 almost at the same time as the call request information. More specifically, the originating mobile terminal 10A is
The simplified information is transmitted to the control station 1 before the call request information is transmitted after the uplink connection is established, or simultaneously with the call request information, or immediately after the call request information is transmitted. As a communication method,
A circuit switching system or a packet communication system is used.

[Transmission and reception of simple information at the time of downlink connection] The control station 1 having received the simple information transmitted from the originating mobile terminal 10A in this way is common to the simple information at the time of calling the downlink connection. It is transmitted to the terminating mobile terminal 10B using the channel, or is transmitted to the terminating mobile terminal 10B using the individual channel after establishing the downlink connection.

When the downlink is connected, the common channel used for transmitting the simple information is, for example, a paging channel (PCH) or a forward access channel (FACH).
Channel). The PCH is a downlink common channel and is a channel used for transmitting a paging signal. The FACH is a downlink common channel and is a channel used for transmitting control information and user data. Note that W-CDMA
The frame in the method is the minimum unit of data encoding / decoding processing. On the other hand, since the PCH is a channel for transmitting paging signals for simultaneous paging from a plurality of base stations, there is a limit to the amount of data that can be transmitted.
Therefore, when the communication system is configured to transmit the simple information by using the PCH, the mobile terminal 10 is configured to transmit the simple information having a data amount that does not impose a load on the communication system. More specifically, the mobile terminal 10 has a function of not allowing creation of simple information exceeding the above data amount limit when the user creates simple information. Further, the mobile terminal 10 prepares only the information that does not exceed the above data amount limit as the simple information of the selection candidate when the user selects. That is, in this case, the simple information candidates displayed on the screen of the display unit 41 are:
Only data that does not exceed the above data amount limit is made.

On the other hand, the dedicated channel at the time of downlink connection is a bidirectional channel which is individually assigned to the incoming mobile terminal 10B after the connection of the link is established, and is used for the transmission of the above-mentioned call information, the transmission of telephone calls and user data. Channel. This individual channel can also transmit simple information having a large amount of data. When the simple information is transmitted using the dedicated channel, the control station 1 sends the simple information to the incoming mobile terminal 10 at substantially the same time as the call information.
Send to B. More specifically, the control station 1 transmits the call information after the downlink connection is established, or simultaneously with the call information, or
Immediately after transmitting the call request information, the simple information is transmitted to the incoming mobile terminal 10B. A circuit switching system or a packet communication system is used as the communication system.

When the downlink is connected,
The control station 1 decides to send the calling information and the simple information to the incoming mobile terminal 10B at substantially the same time because the calling mobile terminal and the mobile terminal sending the simple information are the same calling mobile terminal. This is to make the user of the incoming mobile terminal 10B recognize that it is 10A. In other words, if there is a large difference between the arrival time of the call information and that of the simple information at the incoming mobile terminal 10B, the incoming mobile terminal 10B
The user may mistakenly recognize that the mobile terminal making the call and the mobile terminal transmitting the simple information are different mobile terminals, or may not be able to correctly recognize the relationship between the incoming call and the simple information. Therefore, the control station 1 is supposed to transmit the calling information and the simple information at substantially the same time.

Receiving the simple information transmitted by the control station 1, the incoming mobile terminal 10B sounds the ring tone in response to the calling information at substantially the same time as the simple information is sent to the user (user of the incoming mobile terminal 10B). ) To inform. That is, when the simple information is a message of characters or symbols, or information of an image, the incoming mobile terminal 10B displays the characters or symbols,
The image is displayed on the display unit 41. When the simple information is sound information, the incoming mobile terminal 10B emits the sound from the built-in speaker.

The user of the incoming mobile terminal 10B uses the contents displayed on the display unit 41 and the sound emitted from the built-in speaker to determine the purpose of the user of the incoming mobile terminal 10A. It will be possible to know at the same time as an incoming call whether or not you are calling for a call of importance.

Therefore, the user of the incoming mobile terminal 10B can appropriately and accurately determine whether to receive the incoming call (answer the call), hold it, or hang up (hang up without answering the call). It will be. For example, if the above simple information is a "critical" message,
The user of the incoming mobile terminal 10B can recognize that the incoming call is to convey an urgent and very important content by looking at the message of "danger" displayed on the display unit 41, for example, a telephone call. Even in a situation where it is difficult to get out, it is possible to make an appropriate judgment that the incoming call should be received. As an example, if, as the simplified information is a message "Hello", the user of the incoming mobile terminal 10B, by looking at the message displayed on the display unit 41 "Hello", the incoming emergency It can be recognized that it is related to a call that does not require a call and is of low importance. For example, when it is difficult to answer the call, it can be judged that there is no problem even if the call is put on hold or cut off. . On the display unit 41, it is of course possible to display the telephone number of the callee or the name registered in the address book together with the message of the simple information.

When connecting the uplink or downlink, the channel used for transmitting the simple information is
Whether to use the common channel or the individual channel is a design item of the communication system in FIG. 1, and is a request of an administrator who manages the communication system or a user who uses the communication system, or transmission of simple information. It may be determined according to the available capacity, the processing amount involved in the transmission of the simple information, and the like.
Also, the channel for transmitting the simple information may be only one of the common channel and the dedicated channel, or
It may be appropriately changeable according to traffic or the like.

[Reply of Simple Information] Based on the simple information, the user of the incoming portable terminal 10B having received the simple information as described above receives the incoming call, holds the call, or disconnects the incoming call as described above. And whether or not to return the simple information generated or selected by itself to the originating portable terminal 10A, if necessary. The incoming mobile terminal 10B is capable of returning the simple information to the outgoing mobile terminal 10A even when the simple information is not sent from the outgoing mobile terminal 10A at the time of an incoming call. Further, the incoming mobile terminal 10B stores the simple information created or selected in advance in a memory or the like, and when the user inputs an instruction, or automatically in response to an incoming call, the simple information is received. Can be read and sent to the originating mobile terminal 10A.

Here, in the case of returning the simple information, the incoming mobile terminal 10B uses the downlink dedicated channel to which the connection has already been established, and outputs the simple information created or selected in the same manner as described above to the control station. Send to 1.

The control station 1 having received the simple information transmitted from the incoming portable terminal 10B in this way is sent to the outgoing portable terminal 10A by using the simple information of the uplink which has already established the connection. Send.

The transmitting portable terminal 10A which has received the simple information returned from the incoming portable terminal 10B notifies the user (the user of the transmitting portable terminal 10A) of the simple information. In other words, simple information is a message of characters and symbols,
In the case of image information, the originating mobile terminal 10A displays those characters, symbols, and images on the display unit 41. If the simple information is sound information, the originating mobile terminal 10A emits the sound from the built-in speaker.

The user of the originating portable terminal 10A returns what simple information the user of the incoming portable terminal 10B returns by the contents displayed on the display unit 41 and the sound emitted from the built-in speaker. You will be able to know what you have done.

In other words, the user of the outgoing portable terminal 10A can know whether the user of the incoming portable terminal 10B has the intention to call or what kind of call he / she wants. For example, if the simple information which is the reply is a message "Hello" or "Good morning", the user of the originating mobile terminal 10A, by looking those messages that are displayed on the display unit 41, an incoming cellular It becomes possible to know that the user of the terminal 10B has returned the greeting, and it becomes possible to recognize that there is a high possibility of making a call thereafter. Further, for example, when the returned simple information is a message "I cannot answer the phone now", the originating mobile terminal 10A
By seeing those messages displayed on the display unit 41, the user of can know that the user of the incoming mobile terminal 10B cannot answer the call. Further, for example, when the returned simple information is a message of “contact later”, the user of the originating mobile terminal 10A sees the message on the display unit 41, You can recognize that you cannot answer the call, and you can know that you will make a call later.

[Example of Data Structure of Simple Information] Next, as an example, an example of a data structure in which the transmitting portable terminal 10A uses the individual channel to transmit the simple information to the control station 1 substantially at the same time as the call request information. Will be described with reference to FIGS. 3 and 4.

FIG. 3 shows an example of the data structure in the case where the transmitting portable terminal 10A time-multiplexes the call request information and the simple information and transmits them to the control station 1.

Here, the simple information may be transmitted immediately after the call request information as shown in FIG. 3, or may be transmitted immediately before the call request information. Further, the call request information and the simple information may be continuously transmitted as shown in FIG.
There may be a time gap between the call request information and the simple information. However, the size of the time gap between the call request information and the simple information (that is, the time difference) is within the range in which the control station 1 can transmit the simple information at the same time as the call information in the downlink. Must. That is, in the downlink, the call information to the incoming mobile terminal 10B is generated by the control station 1 according to the call request information sent from the outgoing mobile terminal 10A,
Further, the simple information has to arrive at the incoming mobile terminal 10B almost at the same time as the call information. Therefore, if the time gap between the call request information and the simple information is too large, for example, the control station 1 cannot simultaneously send the simple information and the call information to the incoming mobile terminal 10B. Therefore, the originating mobile terminal 10A determines the size of the temporal gap between the call request information and the simple information as follows.
In the downlink, the control station 1 is within the range in which the simple information can be transmitted at substantially the same time as the call information.

The data amount of the simple information in FIG. 3 is large,
If it does not fit within one frame, the originating mobile terminal 10
A can divide the simple information into a plurality of pieces, and divide each of the divided pieces of information into a plurality of frames to transmit. Further, the originating mobile terminal 10A can also multiplex the call request information and the simple information on one code and transmit it to the control station 1.

In FIG. 4, the originating portable terminal 10A uses the multicode to send the call request information and the simple information to the control station 1.
7 shows an example of the data structure in the case of deciding to send to the. In FIG. 4, the code A is assigned to the call request information,
An example is shown in which the code B different from the code A is assigned to the simple information. Thus, when the multi-code is used, the originating mobile terminal 10A can simultaneously send the call request information and the simple information to which different codes are assigned to the control station 1. In this case, in the downlink, the control station 1 can transmit the simple information to the incoming mobile terminal 10B before the call information, or the simple information at substantially the same time as the call information. When the amount of data of the simple information in FIG. 4 is large and cannot fit within one transmission frame, the originating mobile terminal 10A divides the simple information into a plurality of pieces and divides each of the divided information pieces into a plurality of frames. Can be sent.

Next, referring to FIGS. 5 to 7, an example of the data structure in the case where the control station 1 decides to use the individual channel to transmit the simple information to the incoming portable terminal 10B at substantially the same time as the call information. explain.

FIGS. 5 and 6 show examples of the data structure in the case where the control station 1 time-multiplexes the call information and the simple information and transmits them to the incoming portable terminal 10B.

Here, the incoming portable terminal 10B is adapted to receive the call information and play a ring tone as described above. Therefore, the control station 1 needs to periodically transmit the call information at a certain cycle. Therefore, as shown in FIG. 5, the control station 1 in this case may insert simple information between the call information that is periodically transmitted and may transmit the call information. Before transmitting the information, the simple information may be transmitted first. If the simple information in FIGS. 5 and 6 has a large amount of data and does not fit into the call information that is periodically transmitted, the control station 1 divides the simple information into a plurality of pieces, and divides each of the pieces of the simple information. The information can be inserted between the call information and transmitted. Further, when the data amount of the simple information does not fit in one transmission frame, the control station 1 can also divide the above-mentioned divided information into a plurality of frames and transmit the divided information. Further, the control station 1 multiplexes the calling information and the simple information on one code, and the incoming mobile terminal 10
It is also possible to send to B.

FIG. 7 shows an example of the data structure in the case where the control station 1 decides to use the multicode to transmit the calling information and the simple information to the incoming portable terminal 10B. FIG. 7 shows an example in which the code A is assigned to the call information and the code B different from the code A is assigned to the simple information. As described above, when the multi-code is used, the control station 1 can simultaneously send the call information and the simple information to which different codes are assigned to the incoming mobile terminal 10B. If the amount of simple information in FIG. 7 is too large to fit within one transmission frame, the control station 1
Can divide the simple information into a plurality of pieces, and divide the respective pieces of information into a plurality of frames for transmission.

The call information and the simple information of the data structure shown in FIGS. 3 and 6 may be assigned to the common channel, the individual channel, or both and transmitted.

[Internal Configuration of Mobile Terminal and Its Basic Operation]
Next, the internal configuration of the mobile terminal 10 and its basic operation will be described with reference to FIG. The display unit 41,
Since the operation input unit 44 and the antenna 43 have already been described, their description is omitted here.

In the mobile terminal 10 shown in FIG. 8, the microphone 16 converts the user's call voice or the like into an electric signal (that is, an analog voice signal). The analog voice signal of the call voice is input to a DSP (Digital Signal Processor) 18 after being amplified by an amplifier (not shown).

At this time, the DSP 18 converts the analog audio signal into an A / D (Analog) at a predetermined sampling rate.
/ Digital) convert. The DSP 18 performs CRC for each transport block (TB) on the digital audio data obtained by the A / D conversion.
(Cyclic Redundancy Check) code is added, and channel coding (that is, error correction coding) and interleave processing are performed. The transport block is a basic unit of data processed by the physical layer (MAC (Medium
Access Control) is a unit in which data is transferred from the layer to the physical layer. Further, the DSP 18 performs data modulation after adding overhead such as pilot bits for channel estimation to the bit sequence after the interleave processing. The DSP 18 has an in-phase and a quadrature (Q
uadrature) components are spread by spreading code sequences of two layers. Then, the DSP 18 band-limits the spread chip data sequence to a predetermined band (5 MHz) with a squared cosine root Nyquist filter, and then the D / A (Digita)
l / Analog) conversion to an analog signal. The analog signal obtained by the D / A conversion is the DSP.
It is sent from 18 to the transmission unit 14.

The transmitter 14 quadrature-modulates the analog signal from the DSP 18 and frequency-converts the quadrature-modulated intermediate frequency signal into a high-frequency signal (2 GHz band RF signal). Then, the transmission unit 14 amplifies the high frequency signal and sends the amplified high frequency signal to the duplexer 12 as a transmission signal.

The duplexer 12 is an antenna duplexer. That is, the duplexer 12 shares one antenna 43 for the transmission signal and the reception signal, sends the reception signal from the antenna 43 to the reception unit 13, and the transmission unit 14
It is composed of a filter circuit having a function of transmitting a transmission signal from the antenna to the antenna 43.

The receiving section 13 amplifies the high frequency received signal supplied via the antenna 43 and the duplexer 12, frequency-converts the high frequency received signal into an intermediate frequency signal, and further automatically controls the gain of the signal. Output linearly amplified by. The signal output from the receiver 13 is input to a DSP (Digital Signal Processor) 18.

At this time, the DSP 18 performs quadrature detection on the signal from the receiving section 13 and A / D-converts the in-phase and quadrature component analog signals by the quadrature detection at a predetermined sampling rate. DSP18 is
The in-phase and quadrature components converted into digital values by the A / D conversion are band-limited by the squared cosine root Nyquist filter, and then despread by the same spreading code as the received signal, thereby reducing the propagation delay time. It is time-separated into different multipath components. In addition, the DSP 18
The data of each path separated by the above time is coherent (cohe
rent) Rake combining, de-interleaving and channel decoding (that is, error correction decoding) the data sequence after the Rake combining, and then perform binary data determination,
Reproduce the data sequence transmitted by the other party's terminal. Then, the DSP 18 discriminates the reproduced data series into voice data and other communication data.

The voice data is D / A converted by the DSP 18 and further amplified by an amplifier (not shown).
It is sent to the speaker 17. The speaker 17 is driven by the amplified analog audio signal. This allows
The voice of the call from the terminal of the other party is the speaker 17
Will be emitted from.

Further, the DSP 18 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 18 sends the text data to the control unit 22. At this time, the control unit 22 displays the text data on the display unit 41. Further, for example, when the communication data is compressed image data, the DSP 18 decompresses the compressed image data and then sends the compressed image data to the control unit 22. At this time, the control unit 22 displays the image data on the display unit 41. Further, for example, when the communication data is compressed audio data, the DSP 18 decompresses the compressed audio data and outputs it to the speaker 15 or 17. That is, when the simple information is text data such as characters or image data,
These messages and images will be displayed on the screen of the display unit 41, and when the simple information is voice data, the voice will be output from the speaker 15 or 17.

In addition, when the DSP 18 detects the call information, the DSP 18 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 15. The speaker 15 is driven by the amplified ring tone signal. As a result, the ringing tone corresponding to the call information is emitted from the speaker 15.

The recording section 27 is composed of a rewritable memory such as a flash memory which does not require a memory holding operation. The recording unit 27 records a telephone number, an electronic mail address, an address book, the simple information, etc. registered by the user. The recording unit 27 is also used to record values that can be arbitrarily set by the user among various setting values of the mobile terminal. In addition, the recording unit 27 can record various data such as transmitted / received data such as e-mail, image data, and voice data as necessary.

A ROM (Read Only Memory) 21 is a control program for the control unit 22 to control each unit, a simple information processing program for performing various signal processing when handling simple information, various initial setting values, It stores font data, etc. The ROM 21 is an EEPROM
(Electrically Erasable and Programmable Read Only
A rewritable ROM such as a memory) may be used.

A RAM (Random Access Memory) 20 is
Data is stored as needed as a work area when the control unit 22 performs various types of data processing.

The control section 22 controls the operation of each section based on a control program stored in the ROM 21 and also performs various arithmetic processes. Further, the control unit 22 creates or selects simple information according to an input operation from the operation input unit 44, transmits / receives the simple information, displays the simple information on the display unit 41, and the speaker 15 based on the simple information processing program. Various processing such as control of output to the recording unit 27 and recording and reproduction in the recording unit 27 are performed.

The camera section 26 includes a CCD (Charge Coupled
Devise) image sensor and CMOS (Complementary M)
(etal oxide semiconductor) An image sensor such as an image sensor, and an optical system for forming an optical image of a subject or the like on the image sensor. The input of the photographing instruction with the camera unit 26 can be realized by using a predetermined key on the operation input unit 44 as a release button. The image data captured by the camera unit 26 is input to the DSP 18. The DSP 18 that received the image data
Sends the image data to the control unit 22. At this time, the control unit 22 causes the display unit 41 to display an image based on the image data. Also at this time DSP18
Compresses the image data as necessary, processes the compressed image data as the transmission data, and transmits
It is also possible to send to 4. The compressed image data can be recorded in the recording unit 27 via the control unit 22.

Short-range wireless communication section 24 and its antenna 25
Is for performing so-called Bluetooth wireless communication. The Bluetooth method is a method for realizing ad hoc wireless networking between a plurality of electronic devices. This Bluetooth method is based on the Bluetooth SIG (Special Interest Group
It was formulated by p.), and the details are "Bluetooth (T
M) Special Interest Group, Bluetooth specification version 1.0 ".

The mobile terminal 10 can use the image data, the voice data, etc., which have been captured by the Bluetooth wireless communication, as simple information for transmitting to the mobile terminal of the other party of the call. In addition, the mobile terminal 10 also receives the data of the image captured by the camera unit 26 and the audio data captured by the microphone 16,
It can also be used as simple information to be transmitted to the mobile terminal of the other party of the call.

[Simple Information Processing Operation in Originating Portable Terminal] Next, the flow of the simple information processing operation in the originating portable terminal 10A having the configuration shown in FIG. 8 will be described with reference to the flowchart in FIG. . The flowchart of FIG. 9 shows a flow when the control unit 22 of the originating portable terminal 10A operates each unit based on the control program and the simple information processing program stored in the ROM 21. The flowchart shown in FIG. 9 starts with the power supply of the transmitting mobile terminal 10A turned on. Note that FIG.
Although not shown in the figure, this flowchart ends unconditionally when the power supply of the transmitting mobile terminal 10A is turned off. Further, although not shown in FIG. 9, each processing step can be canceled or returned to the immediately preceding processing step in response to a user's instruction.

First, the control unit 22 of the originating portable terminal 10A
Indicates the standby state of step S11. The control unit 22 at the time of standby is at least the operation input unit 4
The operation signal from 4 is monitored. Although the control unit 22 at the time of standby also monitors the presence or absence of an incoming call, the description of the monitoring of the presence or absence of an incoming call will be omitted.

When the user operates the operation input unit 44 during the standby, the control unit 22 causes the step S12 to be performed.
As the processing of (1), it is determined whether the operation is an operation for making a call or another operation. It should be noted that various other operations such as the operation for creating an electronic mail and the operation for transmitting / receiving the electronic mail can be considered as the other operation. When it is determined in step S12 that the operation is not for making a call (when it is determined to be another operation), the control unit 22 performs a process according to the other operation (not shown in FIG. 9). After that, the process returns to the standby state of step S11. On the other hand, when determining in step S12 that the operation is for making a call, the control unit 22 proceeds to the process of step S13.

When the process proceeds to step S13, the control unit 2
Step 2 determines whether the operation of the operation input unit 44 by the user is an input operation for instructing to make only a call or an input operation for instructing to make a call with simple information. The call instruction with the simple information is an instruction for a call in which the simple information is transmitted at substantially the same time as the calling.

In this step S13, for example, when the telephone number is input and the transmission instruction key is subsequently turned on, similar to the general operation for making a call,
The control unit 22 determines that the user has instructed only the call. In addition, the input of the above-mentioned telephone number means "0"-
This includes not only the input by pressing the number key “9” by the user, but also the case where the user selects a desired phone number from the phone numbers registered in the recording unit 27. The call-instruction key is a key that is generally turned on when making a call. On the other hand, for example, of the keys on the operation input unit 44, when a predetermined key assigned for the start instruction of the simple information processing is turned on, the control unit 22
It is determined that the user has issued a call instruction with the simple information.

When it is determined in step S13 that only the call is instructed, the control unit 22 determines in step S21.
As the process of step S2, after performing a call process to the incoming mobile terminal 10B corresponding to the input telephone number, step S2
Proceed to the process of 2.

When the process proceeds to step S22, the control unit 2
2 determines whether or not a call response has been made from the incoming mobile terminal 10B. When it is determined in step S22 that there is no response to the call, and the user inputs an instruction to stop calling, the control unit 22 returns to the standby process in step S11. On the other hand, when there is a call response from the incoming mobile terminal 10B, the control unit 22 performs step S2.
Proceeding to the processing of No. 3, control for a normal call is performed. During the call processing in step S23, the control unit 22 determines whether or not the call has ended as the processing in step S24. If the call has ended, the process returns to the standby processing in step S11.

On the other hand, when it is determined in step S13 that a call instruction with the simple information is given, the control unit 22
Proceeds to the process of step S14.

In step S13, the control unit 2
It is also possible for 2 to determine which of step S21 and step S14 to proceed according to the set value set in the recording unit 27. That is, this mobile terminal 10 can be set in advance by the user as to whether to make only a call or to make a call with simple information when making a call. In this case, the control unit 22 searches the set value of the recording unit 27 in step S13,
Depending on the set value obtained by the search, step S
21 or step S14 is determined. Further, the control unit 22 may request the user to input an instruction as to whether to make only the call or to make the call with the simple information in step S13. Control unit 2 in this case
2 displays on the display unit 41, for example, a question asking the user whether to make a call only or to make a call with simple information. Then, the control unit 22 performs step S14 or step S21 based on the instruction input by the user corresponding to the display on the display unit 41.
To proceed to any one of the above.

Next, when the process proceeds to step S14, the control section 22 searches the user set value recorded in the recording section 27 to set the automatic transmission of desired simple information by the user. It is judged whether or not it is done.

If it is determined in step S14 that the simple information is automatically transmitted, the process of the control unit 22 proceeds to step S18. When the user inputs a telephone number (including selection of a telephone number), the control unit 22 at this time reads, for example, the simple information for automatic transmission recorded in the recording unit 27, and the input telephone number is input. The simple information is transmitted at substantially the same time as the call is made to the incoming mobile terminal 10B corresponding to the number. Then, the process of the control unit 22 proceeds to step S19. On the other hand, when it is determined in step S14 that the setting for automatically transmitting the simple information is not made, the process of the control unit 22 proceeds to step S15.

In step S14, the control unit 2
2 may request the user to instruct whether or not to automatically transmit the simple information. The control unit 22 in this case, for example,
A display requesting permission for automatic transmission of simple information is displayed on the display unit 41, and when the user gives an instruction to make an outgoing call, the process proceeds to step S18, and the user gives an instruction to disable the outgoing call (or shifts to the next process). When the instruction is given, the process proceeds to step S15.

After proceeding to step S15, the control section 22
The user determines whether desired simple information is selected from a plurality of simple information. This step S15
When making the above determination, the control unit 22 causes the display unit 41 to display, for example, the selection screen on which the plurality of simple information candidates shown in FIG. Then, when any of the simple information is selected from the selection screen, the control unit 22 determines the selected simple information as the simple information to be transmitted to the incoming mobile terminal 10B, as the process of step S16. Then, the process proceeds to step S18. At this time, when the user inputs a telephone number (or selects a telephone number), the control unit 22 determines the above-mentioned determination at substantially the same time as making a call to the incoming mobile terminal 10B corresponding to the input telephone number. Send the simplified information you have made. Then, the process of the control unit 22 proceeds to step S19.

In step S15, for example,
If none of the simple information of FIG. 2 is selected or the item of "new creation" is selected, the process of the control unit 22 proceeds to step S17. When the process proceeds to step S17,
After determining the simple information created by the user operating the operation input unit 44 as the simple information to be transmitted to the incoming mobile terminal 10B, the control unit 22 proceeds to the process of step S18. At this time, when the user inputs a telephone number (or selects a telephone number), the control unit 22 sends the created simple information at substantially the same time as the calling of the telephone number to the incoming mobile terminal 10B. To do. Then, the process of the control unit 22 proceeds to step S19.

In step S15, the control unit 2
The user may request the user to instruct whether to select simple information or to newly create the information before displaying the selection screen of FIG. 2, for example. In this case, the control unit 22 displays, for example, on the display unit 41 to ask the user whether to select simple information or to newly create, and when the user gives an instruction to select, for example, On the other hand, the selection screen of FIG. 2 is displayed. On the other hand, when a new creation instruction is made, the process proceeds to step S17.

Next, in the processing of step S19, the control section 19 determines whether or not the simple information created or selected by the incoming portable terminal 10B has been returned in response to the call. When it is determined in step S19 that the simple information is returned, the control unit 22 displays the simple information on the display unit 41 as the process of step S20, and then proceeds to the process of step S22. , Performs processing depending on whether or not a call is answered.
When it is determined that the simple information is not returned in step S19, the control unit 22 proceeds to the process of step S22 and thereafter performs a process depending on whether or not there is a call response.

[Simple Information Processing Operation in Incoming Mobile Terminal] Next, the flow of the simple information processing operation in the incoming mobile terminal 10B having the configuration shown in FIG. 8 will be described with reference to the flowchart in FIG. . In the flowchart of FIG. 10, the control unit 22 of the incoming mobile terminal 10B uses the ROM 2
2 shows a flow when each unit is operated based on the control program and the simple information processing program stored in 1. The flowchart shown in FIG. 10 starts with the power of the incoming mobile terminal 10B turned on. Although not shown in FIG. 10, the incoming mobile terminal 10B
When the power is turned off, this flow chart ends unconditionally. Further, although not shown in FIG. 10, each processing step can be canceled or returned to the immediately preceding processing step in response to a user's instruction.

First, the control unit 22 of the incoming mobile terminal 10B.
Indicates the standby state of step S31. The control unit 22 at the time of standby at least monitors whether or not there is an incoming call. The control unit 22 at the time of standby is
Although the operation signals from the operation input unit 44 are also monitored, the description of the monitoring of these operation signals is omitted. Also, if there is an incoming call during this standby, the control unit 22
Determines whether the incoming call is an incoming call for a call or another incoming call, as the process of step S32. The other incoming call may be, for example, reception of an electronic mail. When it is determined in step S32 that the incoming call is another incoming call, the control unit 22 performs a process (not shown in FIG. 10) according to the incoming call, and then returns to the standby state in step S31. On the other hand, when it is determined in step S32 that the call is an incoming call, the control unit 22 proceeds to the process of step S33.

When the process proceeds to step S33, the control unit 2
2 determines whether or not the simple information is received at the time of the incoming call. If it is determined in step S33 that the simple information has not been received, the process of the control unit 22 proceeds to step S35. On the other hand, when it is determined that the simple information is received at the time of the incoming call, the process of the control unit 22 proceeds to step S34.

When the process proceeds to step S34, the control unit 2
After displaying the received simple information on the display unit 41 and the like, the process 2 proceeds to the process of step S35.

When the process proceeds to step S35, the control unit 2
2 determines whether the operation of the operation input unit 44 by the user is an input operation for instructing to make a call (receive a call, receive an incoming call). In this step S35, the control unit 22 determines that the user has instructed to make a telephone call when the operation of turning on the reception instruction key is performed, similar to a general operation when receiving a call, and the control unit 22 determines in step S42. Go to processing. It should be noted that the reception instruction key is generally a key that is turned on when an incoming call is received.

When the process proceeds to step S42, the control unit 2
2 controls for a normal call. This step S
During the call processing of 42, the control unit 22 determines whether the call has ended as the processing of step S43,
When the call ends, the process returns to the standby process of step S31.

On the other hand, if it is determined in step S35 that the user's operation of the operation input unit 44 is an input operation other than an instruction to make a call, the process of the control unit 22 proceeds to step S36.

Note that the control unit 22 can also determine in step S35 which of step S36 and step S42 the process proceeds to in accordance with the set value set in the recording unit 27. That is, the mobile terminal 10 allows the user to set in advance whether or not to make only a normal call when receiving an incoming call. In this case, the control unit 22 in step S35, the recording unit 2
The setting value of 7 is searched, and which of step S42 and step S36 to proceed to is determined according to the setting value obtained by the search. In addition, the control unit 22 performs step S
At 35, an instruction as to whether or not to make only a normal call is made.
You may request it from the user. In this case, the control unit 22 displays, for example, on the display unit 41 to ask the user whether to make only a normal call. Then, the control unit 22
Advances to either step S36 or step S42 based on the instruction input by the user in response to the display on the display unit 41.

Next, in step S36, the control unit 3
Reference numeral 6 determines whether or not the operation of the operation input unit 44 by the user is an input operation for instructing to send back simple information. When determining in step S36 that the instruction to return the simple information has been issued, the control unit 22 proceeds to the process of step S37. On the other hand, in step S36,
When it is determined that an operation input other than an instruction to send back simple information, that is, an input operation to instruct to hold or hang up the telephone is performed, the control unit 22 performs a process according to the operation instruction (FIG. 10). Then, the illustration is omitted), and the process returns to the standby state of step S31.

The control section 22 can also determine in step S36 whether to proceed to step S37 or to return to the processing of step S31, depending on the set value set in the recording section 27. . That is, in the mobile terminal 10, the user can set in advance whether or not to proceed to the process of always returning the simple information when it is determined in step S35 that a call is not made. In this case, the control unit 22 controls the recording unit 2 in step S36.
The set value of 7 is searched, and which of step S37 and step S31 to proceed to is determined according to the set value obtained by the search. In addition, the control unit 22 performs step S
At 36, the user may be requested to instruct whether to return the simple information. In this case, the control unit 22 displays, for example, on the display unit 41 to ask the user whether to reply simple information, hold the call, or hang up the phone. Then, the control unit 22 returns to Step S31 or Step S3 based on the instruction input by the user corresponding to the display on the display unit 41.
It is determined whether to proceed to the process of 7.

Next, when proceeding to the processing of step S37, the control unit 22 searches the user set value recorded in the recording unit 27 to set that the user automatically transmits desired simple information. Judgment whether or not it is done.
