Description

How to send e-mail using personal mobile communication

The present invention relates to a mail transmission technique using PERSONAL COMMUNICATION SYSTEM (PCS), and more particularly, to an e-mail using a PCS suitable for transmitting text mail information to a remote server or a personal terminal using a PCS. It relates to a transmission method.

Recently, with the development of semiconductor and communication technology, research and practical use of mobile communication (or personal mobile communication) is actively conducted everywhere, and this mobile communication is digital that can accommodate more subscribers in analog cellular system. It's changing to a cellular system. In addition, the access method of mobile communication is also gradually changing from time division multiple access (TDMA) to code division multiple access (CDMA).

At present, the personal mobile communication in which the practical research is completed and the service is currently in progress, for example, a wireless telephone (aka CT-1), a call-only terminal (aka CT-2), an analog or digital cellular phone ( Or a mobile phone), a PCS that is in the spotlight as a next-generation personal mobile communication, and a common frequency communication (TRS). The present invention relates to a user service improvement technique using a PCS.

On the other hand, PCS terminals for pedestrian-oriented multimedia mobile communication services require a plurality of base stations for communication services, such as CT-2 and mobile phones. Unlike mobile phones using frequencies of 800 MHz, 1.7- Using a frequency range of 1.9 GHz, it can provide a clear communication service without any interference and noise.In addition, unlike a mobile phone that can only talk on the phone while on the move, it is an advanced multimedia that can wirelessly transmit not only voice but also data and video information. Appliance.

In addition, unlike a mobile phone having an 8 Kbps data rate using an 8 Kbps vocoder, PCS has a wider bandwidth of 13 Kbps and adopts CDMA as its transmission method. Thus, PCS can provide faster and higher quality communication services.

On the other hand, two methods are currently considered as a method for sending and receiving data with PCS. In the first method, a PCMCIA card is used to connect an HPC (High Performance Computer) and a PCS terminal using a PCMCIA card, such as a mobile phone. The second proposal is to connect HPC and PCS terminals directly.

In other words, the difference between the two is in which equipment implements the Transmission Control Protocol / Internet Protocol (TCP / IP) protocol used as the communication protocol in the PCS.

At this time, since the first case using the card uses the TCP / IP protocol in the interval from the PCS terminal to the service receiving station, the PCMCIA card is responsible for modulating the data signal to TCP / IP. In addition, in the second case, which is used without a card, the TCP / IP protocol used by the HMC is used as it is throughout the PCS.

In recent years, with the advent of the information age, the use of the Internet, which is called a network of networks, has been widely expanded in each field. Such an Internet realizes a connection between distant host computers (or servers). It provides functions such as data retrieval, data transmission and data reception between them.

On the other hand, using a PCS, a next-generation personal mobile communication, rather than a computer, a service for searching text mail information stored in a personal computer or various servers (that is, a mail server) and receiving the retrieved text mail information is provided. In this case, since the PCS terminal itself cannot receive data, as described above, the PCS is connected to another device (for example, a computer) to receive text mail information desired by the PCS terminal.

On the other hand, if the user wants to transmit text file information to a specific server, for example, a personal computer, a mail server, etc. using a PCS terminal, service for this is currently impossible. In this case, they had to find a notebook computer or a computer environment connected to a network.

That is, in the existing PCS terminal, when the user has only the PCS terminal, when urgently sending a text information mail to a remote server, a service for satisfying this is not possible. Could not meet.

The present invention is to solve the above problems of the prior art, converts a voice message provided from a mobile terminal into a text signal, extracts the voice mail data to be transmitted from the converted text signal, the extracted text mail An object of the present invention is to provide an electronic mail transmission method using personal portable communication capable of transmitting data to a target terminal.

In order to achieve the above object, the present invention provides a communication system including a plurality of PCS terminals, a voice recognition server connected to a base station relaying communication between each PCS terminal, and a remote terminal connected to the voice recognition server. A method for transmitting a voice mail to a remote terminal, comprising: transmitting a voice command message having recognition information of a remote target terminal targeted for electronic mail and a transmission request message composed of voice mail data from a PCS terminal to the voice recognition server; First step; A second step of converting the received voice message into a text signal when the transmission request message is received; A third step of separating the command and text mail data by analyzing the converted text signal; A fourth step of sequentially receiving the separated text mail data until the reception of the separated text mail data ends and sequentially storing the separated text mail data in a predetermined area of the memory; A fifth step of, when the reception of the text mail data is terminated, connecting the voice recognition server and the target terminal, extracting the text mail data stored in the memory, and transmitting the text mail data to the target terminal; And checking a termination of the transmission of the text mail data to the target terminal, and releasing the connection between the voice recognition server and the target terminal when the transmission is terminated. .

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic diagram of a wireless communication system suitable for transmitting an e-mail to a remote server using personal portable communication according to the present invention. The mobile terminal 100, the base station transmission / reception block 200, the voice recognition server 300 and Server 400. The speech recognition server 300 also includes a speech-to-text conversion block 302, a control block 304, and a memory block 306.

Referring to FIG. 1, the portable terminal 100 is a PCS terminal that provides a pedestrian-oriented multimedia mobile communication service, and a user uses the portable terminal 100 as a target terminal, for example, a home or a company. Send a desired e-mail to a personal computer, a mail server, or the like, that is, various messages (e.g., a transfer request message, a transfer start notification message, a transfer end confirmation message, etc.) communicated with each other (ie, between a mobile terminal and a voice recognition server) ) Can be provided with a text mail transmission service.

In addition, the mobile terminal 100 may send a command or voice mail data for transmitting the mail data to the server 400, for example, when a command is input, the voice command is pressed while pressing the # button on the keyboard of the mobile terminal. When inputting the voice mail data, the voice command can be distinguished by inputting the voice command as it is without pressing other buttons. That is, when a voice command is input while pressing the # button, a command message in which additional information (ie, additional information for command recognition) is inserted can be generated.

Therefore, in the control block 304 described later, the command and the mail data can be distinguished from the converted text signal based on the additional information inserted based on the input method.

Meanwhile, in the base station transmission / reception block 200, when a voice message including a command and / or mail data is received from a remote user portable terminal (PCS terminal), the received signal is demodulated to an original signal before wireless transmission, thereby recognizing the voice recognition server. To 300, i. E. To speech / text conversion block 302.

In addition, the base station transmission / reception block 200 wirelessly transmits various messages provided from the voice / text conversion block 302, for example, a transmission start notification message, a transmission end confirmation message, and the like, when performing an email transmission service according to a user's request. The signal is modulated into a signal that can be sent and sent to the mobile terminal 100 that has requested the e-mail transmission service.

On the other hand, the speech / text conversion block 302 in the speech recognition server 300 converts the demodulated voice message including the command and / or mail data into the text information when it is provided through the base station transmission / reception block 200. In this speech / text conversion, as is well known in the art, a phoneme data separation technique used in the combined Hangul or a word separation technique used in the completed Hangul may be used.

When the text information is transmitted from the voice / text conversion block 302, the control block 304 determines whether the text information is a command (remote server connection, server ID or server address, etc.) or mail data to be transmitted. Perform a service control such as access to a remote server 400 according to the command based on the analysis result, and separate the text mail data and store it in the memory block 306, and carry it while the e-mail transmission service is in progress. When confirmation to the terminal user is required, various messages (transmission start notification message, transmission end confirmation message) corresponding thereto are generated.

In this case, the text block information received for transmission to the remote server 400 is stored in the memory block 306, and also various messages (eg, a transmission start notification message and transmission necessary for sending a message to the mobile terminal 100). End confirmation message).

Next, a process of transmitting text mail information to a remote server using a PCS terminal according to the present invention using a wireless communication system having the above-described configuration will be described.

2 is a flowchart illustrating an e-mail transmission process using personal portable communication according to a preferred embodiment of the present invention.

Referring to FIG. 2, when a transmission request message for transmitting an e-mail is transmitted from the portable terminal 100 of FIG. 1 and received by the base station transmit / receive block 200 (step 202), the base station transmit / receive block 200 receives the received request. The e-mail retrieval request message is demodulated and delivered to the speech / text conversion block 302 in the speech recognition server 300.

Accordingly, the voice / text conversion block 302 converts the received voice message into a text signal and forwards it to the control block 304 (step 204). In this case, the transmission request message includes target terminal information, for example, target terminal ID or address, to which mail information is to be transmitted.

Next, in step 206, whether the transmitted text signal is a command (remote server connection, server ID or server address, etc.) or text mail data to be transmitted is analyzed, for example, additional information indicating that it is a command message. Command or mail data is classified according to whether or not to insert a message. When the text signal transmitted according to the analysis result is a command, corresponding control (ie, connection or disconnection of the target terminal) is performed, and the transmitted text is executed. When the signal is mail data, it is received and stored in a predetermined area of the memory block 306 (step 208).

On the other hand, if it is checked in step 210 that the completion of the reception of the text mail data is checked, the control block 304 transmits a transmission start notification message previously stored in a predetermined area of the memory block 306, for example, "received mail." Send data to the target terminal ”and send the message to the mobile terminal 100 (step 214), and using the received recognition information of the target terminal previously received, that is, the target terminal ID or address. 300 and the target terminal 400 are connected (step 216).

Then, when the connection with the target terminal is completed, the text mail data previously stored in the memory block 306 is fetched and transmitted to the target terminal 400 (step 218), and the transmission completion is checked (220).

As a result of the check in step 220, if it is determined that the transmission of the text mail data to be transmitted to the target terminal 400 is completed, the control block 304 confirms the end of transmission previously stored in the predetermined area of the memory block 306. A message, for example, "All received mail data has been sent to the target terminal," and the like is retrieved and sent to the mobile terminal 100 (step 222), and then the voice recognition server 300 and the target terminal 400 are carried out. (Step 224).

As described above, according to the present invention, a voice message can be transmitted using a PCS without a peripheral device (keypad, computer, etc.), and the converted voice message can be converted into text information and transmitted to a target terminal, thereby enabling an electronic mail using the PCS. The service can be greatly improved.
