Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication network system having an Internet mail distribution service function and a message notification service function unique to a communication carrier, and a terminal device used in this system.

[0002]

2. Description of the Related Art Generally, computer network systems and some mobile communication network systems are provided with an Internet mail distribution service function capable of distributing electronic mail via the Internet. Also, it is planned to provide an Internet mail distribution service function in a next-generation mobile communication network system that will start operation in the near future.

For example, in a next-generation mobile communication system, this Internet mail distribution service function is realized as follows. That is, the e-mail created in the transmitting portable terminal is transferred from the portable terminal to the mail server via the network and stored. Note that an attached file can be attached to the e-mail. Upon receiving the e-mail, the mail server sends a reception notification to the destination portable terminal. This reception notification is displayed on the mobile terminal. When the user of the mobile terminal on the receiving side performs an e-mail acquisition operation in response to the reception notification, an electronic mail download request is sent from the mobile terminal to the mail server. The e-mail is downloaded and displayed on the mobile terminal.

The use of the Internet mail distribution service function is very convenient for a portable terminal user because information can be transmitted by e-mail from anywhere at any time regardless of the situation of the communication partner.

[0005]

However, in general, in a terminal having an Internet mail receiving function, when an Internet mail is received, information of a header is displayed first, and then a text is displayed. If there is an attached file, the information is displayed only when the display operation of the attached file is performed. That is, the display form of each element constituting the Internet mail is fixed.
For this reason, for example, even if there is a desire to notify the transmitting user of the information of the attached file to the receiving user first, it is not possible to cope with the request, and the use of the attached file is limited. .

In a general Internet mail distribution service, when an electronic mail is transferred to a mail server, a reception notification is first sent from the mail server to the destination terminal as described above. When the user of the destination terminal performs an acquisition operation, an e-mail is delivered from the mail server to the destination terminal. For this reason, the terminal user on the receiving side has to perform the operation of acquiring the e-mail every time, and this operation is troublesome. Further, in many cases, a message or a mark indicating that there is a received mail is displayed in the reception notification, and the sender cannot be known only by this.

The present invention has been made in view of the above circumstances, and its main purpose is to display a component of Internet mail on a receiving terminal in an arbitrary display mode according to a request of a transmitting terminal user. To be able to
Accordingly, it is an object of the present invention to provide a communication network system and a terminal device thereof that enable the use of attached files to be expanded.

[0008]

In order to achieve the above object, the present invention takes the following measures. In other words, in computer network systems and mobile communication network systems, apart from the Internet mail distribution service function, a so-called short-circuit that allows simple messages to be transferred between terminals subscribing to the same carrier's network using a unique protocol. There is a system having a message notification service function unique to a communication carrier called a message service or the like.

The present invention has been made by paying attention to this function, and responds to this operation when an operation for creating an Internet mail having a specific attached file is performed in the terminal device on the transmitting side. Then, a message unique to the communication carrier including information designating the display form of the Internet mail is created, and the message unique to the communication carrier is transmitted to the same destination together with the Internet mail. On the other hand, the terminal device on the receiving side is provided with a control means for a mail display form, and when the mail display control means receives a message specific to a communication carrier including information specifying the display form together with the Internet mail, Based on the information specifying the display format,
The display form of the text and the attached file constituting the received Internet mail is variably controlled.

Therefore, according to the present invention, when a user performs a specific Internet mail creating operation at a terminal on the transmitting side, a message unique to a communication carrier including information designating a display mode of the Internet mail is correspondingly issued. The message is automatically created and transmitted to the same destination together with the Internet mail, with the message unique to the carrier. On the other hand, at the receiving terminal, when a message specific to the communication carrier including the information for designating the display format is received, the display format of the header information, the body, and the attached file of the Internet mail received together with the message is changed as described above. It is controlled according to the specified information.

For this reason, for example, when displaying a received Internet mail, the Internet mail is displayed in a display order opposite to the normal display order, such as displaying the attached file first, and then displaying the header information and the body. It becomes possible. Further, the text and the attached file can be simultaneously displayed on the same screen.

For example, image data for recognizing the sender, such as a portrait or portrait of the sender, is transmitted by an attached file of the Internet mail, and the attached file is first displayed by a message unique to the communication carrier. Then, the face photograph or portrait of the attached file is first displayed on the terminal on the receiving side. For this reason,
The receiving user can quickly recognize the sender from the displayed face photograph or portrait.

[0013] Also, audio data such as a melody sound set one-to-one between terminals is inserted into an attached file of Internet mail and transmitted, and the attached file is designated to be displayed first by a message unique to the communication carrier. Then, the melody sound of the attached file is reproduced and output on the receiving terminal. Therefore, the receiving side user can quickly recognize the sender by the melody sound.

On the other hand, according to the present invention, when a terminal device on the receiving side receives a message unique to a communication carrier including information designating a display mode, an Internet mail corresponding to the message unique to the communication carrier is transmitted to a network. And transmitting the Internet mail downloaded from the network in response to the request based on the information designating the display mode.

[0015] According to this configuration, even in a system in which the receiving user obtains Internet mail by transmitting a download request from the receiving terminal to the mail server, Internet mail is automatically distributed. become. For this reason, the user on the receiving side does not need to perform any operation of acquiring the Internet mail addressed to the user, thereby improving the operability.

Further, when the communication network system distributes Internet mail from the mail server to the destination terminal, the communication network system first transmits a reception notification, and when the destination terminal user performs an acquisition operation on the reception notification, the Internet notification is transmitted. When configured to send mail, the terminal device on the receiving side displays the attached file information of the received Internet mail instead of the Internet mail reception notification.

In this way, the receiving terminal user can replace the reception notification with the information of the attached file, for example, the image data of the sender's face photograph or portrait, as described above, or one-to-one between the terminals. With the audio data such as the set melody sound, the sender can be quickly and easily recognized.

Further, it is preferable that the transmitting-side terminal device is set so as to transmit an Internet mail after transmitting a message specific to a communication carrier. In this way, a message specific to the carrier can be made to arrive at the receiving terminal earlier than the Internet mail reception notification, thereby controlling the display of the attached file information instead of the reception notification at the reception terminal. Can be executed more reliably.

FIG. 1 is a schematic configuration diagram of a mobile communication network system which is an embodiment of a communication network system according to the present invention.

In the service area covered by the system, a plurality of base stations BS1 to BSn are distributed and arranged, and these base stations BS1 to BSn each form a radio zone called a cell. Also, the base stations BS1 to BS
n is connected to the mobile communication network NW via a wired line. The mobile communication network NW is connected to a computer network such as a wired public network or the Internet (not shown).

The mobile stations MS1 to MSm are connected to base stations BS1 to BSB forming the radio zone in the radio zone.
Sn via a radio channel, the base station BS
1 to BSn are further connected to the mobile communication network NW. By being exchanged and controlled by the mobile communication network NW, the mobile communication network NW is connected to another portable terminal in the system or another wired terminal connected to a wired public network, and, for example, a call can be made between these terminals. Becomes

The mobile communication network NW has, in addition to the exchange control function, an Internet mail distribution service function and a message notification service function unique to a communication carrier in order to perform a mail distribution service.

Among them, the Internet mail distribution service function firstly transmits an e-mail (e-mail) to the mobile terminals MS1, MS2,.
It transfers and distributes via the Internet according to the protocol, and has an e-mail server SV1 for distributing this e-mail.

On the other hand, the message notification service function unique to the communication carrier is called, for example, a short message service, and uses the message server SV2 to allow the mobile terminals MS1, MS2,.
Between them, a text message in which the length of a transmittable message is shorter than that of an E-mail is transferred according to a protocol unique to a communication carrier.

Incidentally, the portable terminals MS1, MS2, MS2
... is constituted as follows. FIG. 2 is a block diagram showing the functional configuration. Radio frequency signals transmitted from the base stations BS1 to BSn are received by the antenna 1 and then input to the receiving circuit (RX) 3 via the antenna duplexer 2 (DUP). In the receiving circuit 3, the radio frequency signal is mixed with the receiving local oscillation signal output from the frequency synthesizer (SYN) 4 and frequency-converted into an intermediate frequency signal. Note that the frequency of the reception local oscillation signal generated from the frequency synthesizer 4 is specified by a control signal SYC from the control unit 12.

The received intermediate frequency signal is subjected to despreading processing by a spreading code (PN code) assigned to a receiving channel in a CDMA signal processing unit 6, and then subjected to quadrature demodulation corresponding to, for example, a QPSK modulation method. Thus, the data is converted into demodulated data in a predetermined format according to the data rate. The converted demodulated data is input to the compression / decompression processing unit 7.

The compression / expansion processing unit 7 performs an expansion process on the demodulated data output from the CDMA signal processing unit 6 according to the reception data rate notified from the control unit 12, and then uses Viterbi decoding or the like. The decoding processing and the error correction decoding processing are performed to reproduce the baseband received voice data or received packet data. The received voice data is output to the PCM code processing unit 8 and the received packet data is output to the control unit 12.

The PCM code processing section 8 includes a compression / decompression processing section 7
PCM decodes the received voice digital data output from, and outputs an analog reception signal. This analog reception signal is amplified by the reception amplifier 9 and then output from the speaker 10 as loudspeaker.

The control unit 12 depackets the received packet data output from the compression / decompression processing unit 7 and stores the depacketed data in the storage unit 13. 15 is displayed. In addition, a portable information terminal (PDA: Person
al Digital Assistance) or a personal computer such as a notebook personal computer, the received packet data may be output to the personal computer via an external interface (not shown).

On the other hand, at the time of voice communication, the input voice signal of the speaker input to the microphone 11 is transmitted to the transmission amplifier 1.
After being amplified to an appropriate level by the PCM 8, the PCM code processing section 8 performs PCM coding processing, and inputs it to the compression / decompression processing section 7 as transmission audio data. Control unit 1
The packet data such as an e-mail and a short message created in step 2 are sent from the control unit 12 to the compression / decompression unit 7.
Is input to

At the time of voice communication, the compression / decompression processing unit 7
The energy amount of the input voice is detected from the transmission voice data output from the CM code processing unit 8, and the data rate is determined based on the detection result. Then, the transmission audio data is compressed into a signal having a format corresponding to the data rate, further subjected to an error correction coding process, and then subjected to CDMA.
Output to the signal processing unit 6. On the other hand, at the time of packet data transmission, the transmission packet data output from the control unit 12 is subjected to error correction coding processing and output to the CDMA signal processing unit 6.

The CDMA signal processing section 6 subjects the carrier signal to, for example, QPSK modulation using the transmission data compressed by the compression / expansion processing section 7, and applies a PN code assigned to the modulated carrier signal to each transmission channel. To perform a spread spectrum process. The spread-coded transmission signal is output to a transmission circuit (TX) 5.

The transmission circuit 5 synthesizes the spread-coded transmission signal with a transmission local oscillation signal generated by the frequency synthesizer 4 and frequency-converts the signal into a radio frequency signal. Then, based on the transmission data rate notified by the control unit 12, the transmission circuit 5 amplifies only the effective portion of the radio frequency signal at a high frequency and outputs it as a transmission radio frequency signal. The transmission radio frequency signal output from the transmission circuit 5 is supplied to the antenna 1 via the antenna duplexer 2,
The signal is transmitted from the antenna 1 to the connected base station.

The input unit 14 is provided with a key group such as a dial key, a transmission key, a power key, an end key, a volume control key, and a mode designation key. Also, the display unit 15
An LCD display and an LED lamp are provided. LCD
The display displays the telephone number of the communication partner terminal, the operation state of the device, and the transmitted and received mails. The LED lamp is used to display the discharge state of the battery 16. Reference numeral 17 denotes a power supply circuit which generates a predetermined operation power supply voltage Vcc based on the output of the battery 16 and supplies it to each circuit section.

The control section 12 has a microprocessor as a main control section. The control functions include a communication link control function for establishing a communication link with a base station in response to an outgoing / incoming call, and a control function for recording / reproducing the voice of the other party using the storage unit 13 during voice communication. In addition to the usual control functions such as a mail transmission / reception control function for individually transmitting / receiving an E-mail or a short message, a photo mail transmission control function 1 is a new function according to the present invention.
2a and a photo mail acquisition and display control function 12b.

The photo mail transmission control function 12a responds to this operation by creating a photo mail attached with a photo and transmitting the photo mail as an e-mail. Create messages automatically. Information for notifying the transmission of the photo mail is inserted into this short message. The photo mail transmission notification information has a function of designating a display mode when displaying the photo mail on the receiving side. Then, the photo mail and the short message for the photo mail transmission notification are sequentially transmitted to the same destination.

The photo mail acquisition and display control function 12b
When the short message is received, it is determined whether the short message is a message for notifying the transmission of a photo mail or a normal short message. If the result of this determination is that the message is a photo mail transmission notification message, a download request is sent to the e-mail server SV1 to obtain a photo mail after waiting for the arrival of a photo mail reception notification from the e-mail server SV1. Is stored in the storage unit 13. Then, the user selects the attached file of the photo mail first, reproduces the image data of the photo inserted in the attached file, and displays the image data on the LCD display of the display unit 15 in place of the notification of the reception of the photo mail. Display.

That is, the control unit 12 of the portable terminals MS1, MS2,...
Thus, a series of processes from receiving the short message to displaying the photo image inserted in the attached file of the photo mail are automatically executed.

Next, the operation of transmitting a photomail in the system configured as described above will be described. FIG. 3 is a flowchart showing a photo mail transmission control procedure and its contents in the transmitting portable terminal, and FIG. 4 is a flowchart showing a photo mail acquisition and display control procedure and its contents in the receiving portable terminal.

For example, assume that a photo mail is transmitted from the portable terminal MS1 to the portable terminal MS2. In the portable terminal MS1, the user first selects and displays a template for transmitting a photo mail, and in this state, inputs a text in step 3a, and subsequently, in step 3b, attaches an attached photograph stored in the storage unit 13 in advance. And attach the image data as an attached file to the text. Then, in step 3c, the destination address of the portable terminal MS2 is selected from the address book and inserted into the header.

Then, when the creation of the photo mail is completed,
When the user presses the operation button, the control unit 12 of the mobile terminal MS1 shifts from step 3d to step 3e, where a short message for notifying the transmission of the photo mail is created. To create a short message for the photo mail transmission notification, insert an identification code indicating the photo mail transmission notification into the message body, and insert the destination address and subject described in the photo mail header into the message header. It is performed by Note that a code that is not assigned to the character code system used in the short message is used as the identification code.

When the creation of the short message for notifying the transmission of the photo mail is completed, the control unit 12 proceeds to step 3f.
Transmits the above-mentioned photo mail (E-mail), and then transmits the above-mentioned short message for photo mail transmission notification in step 3g. The photo mail is sent to the mobile terminal MS1
Is transmitted to the mobile communication network NW via the base station BS1 and then stored in the e-mail server SV1 as shown in FIG. On the other hand, the short message for notifying the photo mail transmission is sent from the mobile terminal MS1 to the mobile communication network NW via the base station BS1, and then stored in the message server SV2 as shown in FIG.

On the other hand, the portable terminal MS2 on the receiving side monitors the arrival of the short message in step 4a during the standby period as shown in FIG. In this state, it is assumed that a short message addressed to itself arrives from the message server SV2 as shown in FIG.

Then, the control unit 12 of the portable terminal MS2
First determines in step 4b whether the received short message is a photo mail transmission notification message or a normal message. If it is a normal short message, the normal short message display control is performed thereafter.

On the other hand, if the message is a photo mail transmission notification message, the flow shifts to step 4c where the arrival of an e-mail reception notification from the e-mail server SV1 is monitored. In this state, as shown in FIG. 5, when an e-mail reception notification arrives from the e-mail server SV1, and it is confirmed that the reception notification is the photo mail notified by the previously received photo mail transmission notification short message. Then, the control unit 12 shifts to step 4d, where it transmits a photo mail download request to the e-mail server SV1. At this time, the reception notification is displayed on the display unit 1.
5 and no ringing tone is generated.

When a photo mail arrives from the e-mail server SV1 as shown in FIG. 5 in response to the download request, the control unit 12 receives this photo mail at step 4e and stores it in the storage unit 13. And Step 4
At f, a mail ringtone is output to notify the user of the incoming e-mail. At the same time, in step 4g, the attached file of the photo mail is selected, the image data inserted in the attached file is decoded to reproduce the photographic image, and the photographic image is displayed on the display unit 1.
5 is displayed on the LCD display.

Therefore, the user of the portable terminal MS2
It is possible to instantly recognize the sender by knowing the arrival of the e-mail from the ringing tone and looking at the photographic image displayed on the LCD display.

In this state, when the user performs an operation for displaying the text, the control unit 12 performs steps 4h to 4i.
Then, the corresponding header and body of the photo mail are read from the storage unit 13 and displayed on the LCD display.

As described above, in the present embodiment, a mobile communication network system having an e-mail distribution service function and a short message notification service function is provided. When the operation is performed, the photo mail transmission control function 12a automatically creates a photo mail transmission notification short message in response to the operation, and transmits the photo mail transmission notification short message together with the photo mail to the same destination. . On the other hand, the mobile terminal M on the receiving side
In S2, upon receiving the photo mail transmission notification short message, the photo mail acquisition display control function 12b transmits a download request to the email server SV1 in response to the reception notification from the email server SV1, and transmits the photo mail. Acquired, the attached file of the photo mail is selected first, and the photo image data is displayed instead of the above-mentioned reception notification.

Therefore, according to this embodiment, when the e-mail is distributed, the receiving terminal user can immediately recognize the sender by the face photograph or the portrait transmitted by the attached file. Email server SV1
Since the download request and the receiving procedure of the photo mail are automatically executed, the receiving terminal user does not need any operation for obtaining the photo mail, thereby improving the operability.

In the above-described embodiment, since the short message is transmitted after the transmission of the e-mail, the short message may reach the receiving terminal later than the notification of the reception of the e-mail. However, in general, the transfer procedure of a short message is simpler than the transfer procedure of an e-mail, and the packet length is shorter, so that the transfer time of the short message is shorter. Therefore, E
If the transmission timing is set so that the transmission time difference between the e-mail and the short message is shorter than the required transmission time difference between the e-mail and the short message, the above-mentioned concern does not occur and the photo mail acquisition and display control is always performed reliably. it can.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, when transmitting a photomail in the mobile terminal MS1 on the transmitting side,
The case where the photo mail is transmitted first, and then transmitted in the order of the short message for transmission notification has been described as an example. However, as shown in FIG. 6, a short message for notifying the transmission of a photo mail may be transmitted first, and then the photo mail may be transmitted.

In this way, the mobile terminal MS on the transmitting side
1 transmits the e-mail and the time required for the reception notification to reach the receiving portable terminal MS2, and the transmitting portable terminal MS1 transmits the short message, and this message is transmitted to the receiving portable terminal MS2. Even if the time required to reach the e-mail is almost the same, the short message can be received by the portable terminal MS2 on the receiving side earlier than the e-mail reception notification, whereby the photo mail acquisition and display control can be executed more reliably. Becomes possible.

In some cases, the e-mail server SV1 has a function of selectively downloading a header, a body, and an attached file in response to a request from the receiving terminal as an e-mail download function. In this case, upon receiving the short message for the photo mail transmission notification, the receiving terminal waits for the photo mail reception notification, transmits a request for downloading the attached file to the e-mail server SV1, and acquires the attached file, The image data of the photo inserted in the attached file is reproduced and displayed in place of the reception notification. Then, when the user performs a text display operation in this state, the e-mail server SV1
It is possible to control to transmit a text download request to acquire and display the text.

Furthermore, in the above-described embodiment, a photo mail has been described as an example of the type of e-mail that is used in combination with a short message. However, the present invention is also applicable to a case where a music mail is transmitted.

That is, in the terminal on the transmitting side, audio data of music or melody sound arbitrarily selected or created by the transmitting user is inserted into the attached file of the e-mail and transmitted. Note that MIDI or MP3 can be used as a coding method for music or melody sound. At the same time, in response to the music mail creation or transmission operation, a short message in which the music mail transmission notification information is inserted is created, and the short message is transmitted to the same destination together with the music mail.

On the other hand, upon receiving the short message in which the music mail transmission notification information is inserted, the receiving terminal waits for a music mail reception notification from the E-mail server, and then requests the E-mail server to download the music mail. To get a music mail for yourself. Then, the user selects the attached file of the music mail, reproduces music or a melody sound from the audio data, and outputs the music or melody sound in place of the ringing tone generated when an e-mail reception notification is received.

In this manner, the receiving user can identify the transmitting user by music or melody sound. Instead of music or melody sound, the sender's own voice may be input from the microphone, inserted into the attached file, and transmitted.

Further, the transmitting terminal inserts image data such as a photograph and audio data such as music, melody sound, and the voice of the sender into the attached file of the e-mail, and sends a short message to that effect. Send with. Then, the receiving terminal can reproduce and display the image data of the photograph in place of the e-mail reception notification, and at the same time, reproduce and output the music, the melody sound, and the voice of the sender at the same time. It is.

Further, in the above embodiment, the mobile communication network system has been described as an example. However, if the network system has both an e-mail distribution service function and a message notification service function unique to a communication carrier, a public wired network can be used. In addition, the present invention can be applied to an in-house network, a CATV network, and the type of terminal device is not limited to a portable terminal, but may be a personal computer or a web television connected to a wired line.

In addition, the configuration of the network system,
E-mail and short message distribution procedures, e-mail transmission control procedures and e-mail acquisition and display control procedures in the terminal device can be variously modified and implemented without departing from the gist of the present invention.

[0062]
