Description

How to search e-mail using personal mobile communication

The present invention relates to a mail retrieval technique using PERSONAL COMMUNICATION SYSTEM (PCS), and more particularly, to retrieve a text mail received and stored in a remote server or a personal terminal using the PCS, and the retrieved text. The present invention relates to an e-mail retrieval method using a PCS suitable for receiving mail information in a PCS.

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 itself cannot receive data, as described above, the PCS and other devices (eg, computers) can be connected to receive the desired text mail information.

That is, conventionally, the text mail information of the server cannot be received using only the PCS itself, and the text mail stored in the server can be received only by combining with other auxiliary devices, so that the user has only a PCS terminal. When you want to receive a text mail from a remote server, there is a problem that the service is not possible, that is, it can not meet the user's various service needs due to the limitation of such service.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and based on a voice command using a keyword, the text mail stored in the target terminal is searched at high speed, and the retrieved text mail information is adapted to the portable terminal as voice or text information. An object of the present invention is to provide an electronic mail retrieval method using personal mobile communication.

In order to achieve the above object, the present invention provides a remote terminal to the PCS terminal in 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 retrieving an e-mail of claim 1, comprising: retrieving a search request message including a recognition information of a remote target terminal targeted for an e-mail search, a voice keyword for retrieving an e-mail, and a password of the target terminal from the voice recognition server; Transmitting to the first step; Receiving the search request message, analyzing the received message to extract the inserted voice keyword, converting the extracted voice keyword into a text keyword, and then connecting the target terminal to the voice recognition server; A third step of searching for a text file stored in the target terminal based on the converted text keyword when comparing the received password extracted from the received message with a preset password of the target terminal; A fourth step of transmitting a corresponding search result notification message to the PCS terminal and releasing the connection when there is no text file to be found in the target terminal in the search result in the third step; And a fifth step of retrieving the text file information retrieved from the target terminal in response to a user request message when the text file to be found in the target terminal exists in the third step, transmitting the retrieved text file information to the PCS terminal, and releasing the connection.

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 retrieving e-mail using personal mobile communication according to the present invention, which includes a mobile terminal 100, a base station transmission / reception block 200, a voice recognition server 300, and a server 400. ). The speech recognition server 300 also includes a speech recognition control block 302, a switching block 304, and a text / voice conversion 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. Various messages communicated with each other (i.e., between a mobile terminal and a voice recognition server) to execute a search and transmission request of an e-mail (i.e., text mail) stored and received (or received) in a personal computer, a mail server, or the like. (E.g., a search request message, a transfer request message, etc.), various services of text mail can be provided.

Meanwhile, in the base station transmission / reception block 200, when a message or voice data is received from a remote user portable terminal (PCS terminal), various messages related to the service of the voice mail are extracted from the received signal, and the voice mail service thus extracted. Relevant messages are provided to the speech recognition control block 302 via line L11.

In addition, the base station transmission / reception block 200 modulates various messages provided from the voice recognition control block 302 when performing an e-mail service, for example, a password error message, a password retransmission request message, a warning message, and the like. Is sent to the requesting portable terminal 100, and when voice mail or text mail is provided through line L17 according to the user's request, the mail information is modulated and transmitted to the portable terminal 100.

On the other hand, the voice recognition control block 302 in the voice recognition server 300 analyzes when various messages related to the e-mail service are received from the base station transmission / reception block 200 and performs the corresponding e-mail service control. And, when the response (or approval) of the user of the mobile terminal is required during the e-mail service, various messages corresponding thereto are generated, and for the e-mail service, the remote server 400, for example, a personal computer, a mail server, etc. The connection is controlled, and the withdrawal of the text mail received by the server 400 is controlled.

In addition, the voice recognition control block 302 converts the voice keyword extracted from the received message into text information, retrieves the stored text mail based on the converted text keyword, and transmits a request for transmission of the e-mail retrieved from the mobile terminal 100. When there is an e-mail information retrieved from the remote server 400 via the line L15 is retrieved.

In addition, the voice recognition control block 302 performs control for transmitting the retrieved e-mail in voice or in text in response to the e-mail transmission request signal received from the mobile terminal 100.

That is, the voice recognition control block 302 controls the transmission to voice or text by generating a switching control signal CS to switch the contact point of the switching block 304. When the retrieved e-mail information is transmitted as text, the switching block ( The contacts ab of 304 are connected, and the contacts ac of the switching block 304 are connected when transmitting by voice.

Meanwhile, the text / voice conversion block 306 converts the text mail information provided from the server 400 through the line L15 into a voice signal when the user requests transmission of the retrieved e-mail. As is well known in the art, it is possible to use the phoneme data separation technique used in the combined Hangul or the word separation technique used in the completed Hangul.

On the other hand, the remote server 108 may be, for example, a personal computer or a mail server at home or at a company, where an e-mail requested via line L15 is provided when a transmission request signal of the e-mail is provided via line L13. That is, text information) is provided to the contact a of the switching block 304 and the text / voice conversion block 306, respectively.

Next, a process of retrieving an e-mail of a remote server and performing a transmission service of the retrieved e-mail according to the present invention using the wireless communication system having the above-described configuration will be described.

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

Referring to FIG. 2, when a request message for requesting an e-mail search is transmitted from the portable terminal 100 of FIG. 1 and received by the base station transmission / reception block 200 (step 202), the base station transmission / reception block 200 receives the electronic message. The mail retrieval request message is demodulated and passed to line 141 via voice line control.

Next, the voice recognition control block 302 analyzes the transmitted search request message, that is, the search request message is used to search for target terminal information (eg, personal computer, mail server, etc.), password, A keyword (i.e., a voice signal) is included, and in step 204, each of these pieces of information is extracted and analyzed, and the extracted voice keyword is converted into a text signal.

Then, the voice recognition control block 302 connects the target terminal requested by the user (i.e., the server 400) according to the analyzed target terminal information (step 206), and the received password and the preset terminal of the target terminal. It is checked whether the passwords match each other (step 208).

As a result of the check in the step 208, if it is determined that the received password and the predetermined password of the target terminal do not match each other, the process proceeds to step 210 to signal processing such as transmission of an error message due to incorrect password. The process is performed, and the detailed operation process in this step 210 will be described in detail with reference to FIG. 3.

FIG. 3 is a flowchart illustrating a detailed processing of the error message transmitting step shown in FIG. 2.

Referring to FIG. 3, when the received password and the preset password of the target terminal are different, an error message, for example, is transmitted to the mobile terminal 100 at the remote location through the base station transmission / reception block 200 in the voice recognition control block 302. An error message such as "The password is incorrect and cannot be accessed to the target terminal, please resend the password", etc. is sent, and then a new password is awaited (step 302).

Next, in step 304, it is checked whether a new password has been received, and as a result of the check, there is no input (i.e., reception) of a new password within a predetermined time period (e.g., 5 seconds, 8 seconds, etc.). If judged, the process proceeds to step 306 to increase the count value n, which indicates the number of times the input password is received, by one.

On the other hand, in step 308, it is checked whether the increased count value n has reached the preset count value m. Here, the preset count value can be set three times, for example, three times. If the password is incorrect due to a user's mistake or the like, it means that the user is given three chances to re-enter (or resend) the new password.

Therefore, if it is determined in the step 308 that the current count value n has not reached the preset count value m, the process returns to step 302 described above to repeat the subsequent steps. do.

In addition, if the check result in the step 308 determines that the current count value n has reached the preset count value m, that is, it is determined that there is no input of a new password for a predetermined number of repetitions, a warning message accordingly For example, a message such as "There is no input of a new password to block access to the target terminal" is transmitted to the remote portable terminal 100 (step 314), and then a message with the target terminal (ie, the server 400). The connection is released (step 316).

On the other hand, if the new password is input within the predetermined time period as a result of the check in the above-described step 304, the count value n indicating the number of reception of the input password is increased by one (step 310), and then the increased count value n is increased. It is checked whether or not the preset count value m has been reached (step 312).

If it is determined in step 312 that the increased current count value n has not reached the preset count value m, then the process returns to step 208 of FIG. 2 to repeat the subsequent process. do.

In addition, if it is determined in step 312 that the increased current count value n has reached the preset count value m, the process returns to step 314 described above and transmits a warning message and at the same time the target terminal. Disconnect from.

Referring back to FIG. 2, if it is determined that the received password and the preset password of the target terminal match each other, the voice recognition control block 302 extracts the received message and converts it into a text signal. In order to search e-mail (i.e., text file information) stored in the target terminal, that is, the server 400, using one keyword (step 212), the present invention uses a text keyword unlike the conventional method. The voice mail is searched for, so that a faster and faster search can be realized.

On the other hand, to check whether there is a voice mail searched based on the search result in the step 212, the text keyword (step 214), the e-mail searched by the check result here, that is, the text file that the user is looking for If it is determined that there is no message, a corresponding message, for example, "no e-mail to find" is generated, transmitted to the mobile terminal 100 (step 216), and then disconnected from the mobile terminal. (Step 222).

On the other hand, if the check in the step 214 determines that the searched e-mail, that is, the text file that the user wants to find, exists, the process proceeds to step 218 to send a signal such as sending an e-mail corresponding to the search result. The process is performed, and the detailed operation process at this step 218 will be described in detail with reference to FIG. 4, which shows the detailed process.

FIG. 4 is a flowchart showing a detailed process of the mail transmission step shown in FIG. 2.

Referring to FIG. 4, when there is a voice mail searched using a keyword, the search result information is notified to the mobile terminal, for example, "There are two searched voice mails. Send a voice message to the mobile terminal 100 and wait for a response (transmission request) accordingly (step 402).

Next, in step 404, it is checked whether a response message has been received, and there is no input (i.e., reception) of a transmission request message within a predetermined time period (e.g., 5 seconds, 8 seconds, etc.) as a result of the check. If it is determined that the process proceeds to step 406, the count value n representing the number of receptions of the transmission request message is increased by one.

On the other hand, in step 408, it is checked whether the increased count value n has reached the preset count value m. Here, the preset count value can be set 3 times, for example, 3 times. This means that the transmission opportunity of the transmission request message is given three times.

Therefore, if it is determined in the step 408 that the current count value n has not reached the preset count value m, the process returns to step 402 described above to repeat the subsequent steps. do.

Further, if it is determined in the step 408 that the current count value n has reached the preset count value m, i.e., there is no input of the transfer request message for a predetermined number of repetitions, the process is performed. Proceeding to step 410, the connection with the mobile terminal 100 is forcibly released.

On the other hand, if the transmission request message is received within a predetermined time period as a result of the check in step 404 described above, in step 412 the transmission request message received from the mobile terminal 100 is a voice information request message or text. It is checked whether or not it is an information request message. When the result of the check here is a text information request message, the contact ab of the switching block 304 is connected in accordance with the switching control signal CS from the voice recognition control block 302. The retrieved text information on the line L15 is transmitted to the base station transmit / receive block 200 through the line L17, and as a result, the retrieved text information will be sent to the mobile terminal 100. Subsequently, the process proceeds to step 220 of FIG. Proceed.

In this case, the mobile terminal 100 transmits the base station transmission / reception block 200 to the voice recognition server 300 by providing the text information request message to the voice recognition server 300. Means that the 100 is connected to a peripheral device such as a computer.

On the other hand, if the request message received as a result of the check in step 412 is a voice information request message, the contact ac of the switching block 304 is connected in accordance with the switching control signal CS from the voice recognition control block 302. As a result, the retrieved text file information retrieved from the server 400 through the line L17 is converted into a voice signal through the text / voice conversion block 306, and the converted voice information is converted into a base station transmission / reception block (through the line L17). By being transmitted to 200, the voice information of the retrieved text file will be sent to the mobile terminal 100, and the process thereafter proceeds to step 220 of FIG.

That is, referring to FIG. 2, in step 220, it is checked whether the connection between the portable terminal 100 and the voice recognition server 300 is terminated, and when the connection termination message is received from the portable terminal 100, the portable terminal 100 is checked. The connection between the 100 and the voice recognition server 300 is terminated (222).

As described above, according to the present invention, a PCS based on a voice message containing a voice keyword is used to quickly retrieve an e-mail (text file) at a target remote server, and retrieve the retrieved e-mail information. It can be adaptively provided as voice information or text information according to the user's request, and can greatly improve the e-mail service using the PCS.
