Hereinafter, a method and apparatus for providing a voice call service for searching for information using called party information according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. The same or corresponding elements will be given the same reference numeral string, and duplicate description thereof will be omitted.

1 is a schematic diagram showing an overall system for providing a voice call service for searching for information using called party information according to an embodiment of the present invention, Figure 2 is a call according to an embodiment of the present invention A diagram illustrating inputting called party information in a terminal.

According to FIG. 1, the entire system for providing a voice call service for retrieving information using called party information includes a calling terminal 10, a switch 30, 35, a base station 40, 41, and a wired switch 45, 46. , The location register 50, the number management device 70, and the information providing terminal 90.

The calling terminal 10 is a terminal capable of internet access such as a wireless communication terminal (LAN) terminal, a Bluetooth terminal, a portable Internet terminal, as well as a mobile communication terminal including a PCS, PDA, smart phone, and the like. It refers to all terminals capable of voice calls. Hereinafter, a mobile communication terminal will be described as an example, but as described above, all terminals capable of a voice call can be applied in the same manner.

The calling terminal 10 may not only connect the called party information to a general telephone number when requesting a voice call, but also transmit the called party information to a string or a string corresponding to the string according to the voice call service according to the present invention. A voice call can be made with the information providing terminal 90. In particular, the information providing terminal 90 provides voice information corresponding to the search word in the character string to the calling terminal 10 when a call is connected.

Therefore, when the calling terminal 10 requests a voice call, in inputting the information providing terminal 90 to call and the called party information about the search term to be searched, the calling party information is input using not only a number (number string) but also a string. It is desirable to provide a user interface to do so.

Referring to FIG. 2, when the user of the calling terminal 10 inputs '* search * gull' and presses a call button to obtain information about a seagull, the user of the calling terminal 10 may call the information providing terminal 90 corresponding to the search, which is a reserved word. It is set and listens to the voice information about the seagull provided from the information providing terminal 90 to which the call is connected.

Here, the first * is an identifier for the originating terminal 10 to generate service identification information that the mobile communication network can recognize that the called party information is a numeric string corresponding to a character string. In addition, service identification information may be generated by other identifiers such as # and pressing a specific function button. Also, the second * is a character delimiter for distinguishing the search word search and the search word gull. Similarly, the second * can be distinguished from the reserved word and the search word by another identifier such as # and pressing a specific function button.

Here, the reserved word is called terminal identification information for distinguishing the information providing terminal 90. For example, the information providing terminal 90 providing a search function provides a reservation function such as 'search', a movie ticket or a theater ticket. The information providing terminal 90 may be set as a 'reservation', and the information providing terminal 90 providing a schedule management function may be set as a 'schedule' and the like. In addition, it is obvious that all the information providing terminals 90 capable of providing respective voice information such as weather, sports, and news may be applied.

In another example, the user reserves a movie through the calling terminal 10. By inputting a string of '* reservation * Spider-Man' or a string of numbers corresponding thereto, information on a ticket corresponding to the search term Spider-man is provided from the information providing terminal 90 corresponding to the reserved word. Of course, the calling terminal 10 may perform the booking procedure after acquiring the information. In addition, a movie ticket to a theater close to the current location may be reserved through the location information of the calling terminal 10. The voice call processing procedure for the above-described examples will be described later with reference to the drawings.

In addition, the calling terminal 10 outputs the inputted called party information on the screen. You can print only one string or a string, or both. The string does not have to be Korean and strings of other languages such as English can be entered. That is, the character string corresponding to the input numeric string is converted and displayed.

Here, since the first identifier * means inputting the called party information as a character (the service according to the present invention), only the second identifier * may be output so that the reserved word and the search word can be distinguished without being displayed on the screen. As shown in FIG. 2, * may be output between the reserved word and the search word, but may be converted into a symbol such as '-' in order to output a nice screen to the user on the UI.

The incoming called party information is preferably transmitted to the communication network in the form of a string, but may be transmitted in the form of a string. In the conventional mobile communication network, when the call request from the calling terminal 10 processes the called party information only in the form of a numeric string, a system capable of processing the called party information in the form of a string in the future may be developed. (10) may transmit the called party information in a character format (for example, ASCII of 1 byte or KSC5601 of 2 bytes).

Referring back to FIG. 1, the exchange 30 sets up a call for a call between the information providing terminal 90 and the calling terminal 10 corresponding to the called party information corresponding to the call request message received from the calling terminal 10. It performs the function. When the call is connected, the exchange 30 transmits the search word identifier received from the number management device 70 to the information providing terminal 90 such that the information providing terminal 90 provides voice information on the search word to the calling terminal 10. do.

Typically, the exchange 30 receives the telephone number of the receiving side from the calling terminal 10, and information on the information providing terminal 90 (location, corresponding exchange 35) from the location register corresponding to the receiving telephone number. And the like) to establish a call with the corresponding exchange 35. According to the present invention, the exchange 30 receives the character string corresponding to the character string or the character string (hereinafter referred to as the character string string) from the originating terminal 10, rather than the telephone number, through the number management device 70 The actual telephone number (hereinafter referred to as the called number) of the information providing terminal 90 is obtained.

According to the process of the existing communication network, when the called party information includes the service identification information, the exchange 30 recognizes that the service identification information is included and transmits the called party information to the location register 50, the number management device 70 The called party's called number is received from the position register 50 obtained from the caller ID.

Alternatively, if the exchange 30 can recognize that the called party information is a character string, the exchange 30 manages the called number by sending the called party information to the number management device 70 without passing through the location register 50. May receive from device 70. Therefore, in the second case, the calling terminal 10 does not need to transmit separate service identification information to the exchange as described above.

The base stations 40 and 41 (including base station controllers) perform relay functions for communication between each terminal and the exchanges 30 and 35. Since the base station and the base station controller will be apparent to those skilled in the art, a detailed description thereof will be omitted.

The wired exchanges 45 and 46 perform a function of setting up a call of a wired telephone. That is, it performs a function similar to that of the switches 30 and 35 for setting up calls of wireless terminals such as mobile terminals. Typically, the wired switch 35 receives the telephone number of the receiver from the calling terminal 10 and establishes a call with the corresponding switch corresponding to the telephone number of the receiver. Here, when the wired switch 45 receives the called party information, which is a string or a string of numbers corresponding to the string, from the calling terminal 10, the wired switch 45 receives the called number corresponding to the string from the number management device 70 connected through the network. The function according to the remaining call connection is similar to the switchboard 30, and will be omitted since the description will be apparent to those skilled in the art.

The location register 50 performs a function of storing information of a subscribed terminal. Currently used location registers include a home location register (HLR) and a visit location register (VLR), and there is a location register associated with each terminal subscriber. The location register stores the subscribed service information, location information, and the like of the associated terminal. The exchange 30 may recognize the called party location register through the called party number of the received information providing terminal 90, obtains information of the information providing terminal 90 through the called party location register, and establishes a call. Since a description thereof will be apparent to those skilled in the art, a detailed description thereof will be omitted, and it is apparent that all devices for storing subscriber information may be equally applied in addition to the above-described location register 50.

Typically, the location register 50 stores not only the voice call service using the character string according to the present invention, but also information on other subscribed services. It determines whether to subscribe to the service through the information (calling terminal information and called party information) received from the calling terminal 10 via the exchange 30, and provides the corresponding service through the received identification information. Recognizing the identification information of the service according to the present invention, the location register 50 transmits the called party information to the number management device 70, thereby receiving the converted called number in the numeric format of the information providing terminal 90. have. The location register 50 sets up a call between the originating terminal 10 and the information providing terminal 90 by transmitting the received called number to the exchange 30.

The number management device 70 is a called number of the information providing terminal 90 corresponding to a character string or a string of characters transmitted from the calling terminal 10 for the voice call connection between the calling terminal 10 and the information providing terminal 90. It provides a function to provide a mobile communication network. Here, the number management device 70 transmits the information about the search word to the information providing terminal 90 so that the information providing terminal 90 provides voice information corresponding to the search word.

When the call is connected to the calling terminal 10, the information providing terminal 90 performs a function of providing the calling terminal 10 with relevant voice information corresponding to a search word. The information providing terminal 90 according to the present invention includes not only a general server connected to the exchange 35, but also a mobile terminal communicating with the base station 41, a terminal providing information through the wired switch 46, and the like. The server connected to the exchange 35 among the information providing terminals 90 may be an automatic response system (ARS), and the information provider providing corresponding information through the mobile terminal may be a general user. That is, a user having specialized knowledge in a specific field becomes an information provider, and the mobile terminal of the user becomes an information providing terminal 90 so that the mobile terminal (information providing terminal) of the information provider is the calling terminal 10. It can be connected to and provide this information.

The information providing terminal 90 provides a search term identifier or a called number corresponding to the search word received from the number management device 70. Since the information providing terminal 90 provides voice information corresponding to a search word at the time of a call connection with the calling terminal 10, it should be able to recognize the search word at the time of a call connection.

According to an exemplary embodiment of the present invention, the information providing terminal 90 may be applied with a method of receiving a search word identifier from a mobile communication network when a call is connected. The search term identifier is generated by the information providing terminal 90 when the search term is received from the number management apparatus 70 and transmitted to the number management apparatus 70, and the number management apparatus 70 includes the search term identifier in the called number. To the mobile communication network. Subsequently, when the mobile communication network requests a call connection to the information providing terminal 90 using the called number, the information providing terminal 90 recognizes the corresponding search word through the search word identifier.

According to another preferred embodiment of the present invention, the information providing terminal 90 receives and stores the calling terminal information with the search word from the number management device 70. Then, by recognizing the calling terminal connected to the call, the corresponding search word is recognized.

According to another preferred embodiment of the present invention, the information providing terminal 90 has a plurality of called numbers, and receives a plurality of called numbers request message including a search word from the number management device 70 Any one of the called numbers is provided to the number management device 70 and temporarily stores the provided called number and search word. Thereafter, the caller terminal 10 recognizes the corresponding search word as it recognizes the called number which is connected when the call is connected with the calling terminal 10.

As described above, the information providing terminal recognizes a corresponding search word when a call is connected with the calling terminal 10 through interworking with the number management device 70 and provides voice information accordingly. In the following description, a method using a search term identifier corresponding to a search word is described as an example of the above-described method for recognizing a search word, and the remaining two methods may be applied in the same manner. .

Therefore, the information providing terminal 90 is a voice information providing means such as ARS for providing voice information through a communication network, and communication means for performing data communication with the number management device 70 via a wired or wireless network (of course, moving). Naturally, data communication can be performed through a communication network), search term identifier generating means corresponding to the search word, voice information generating means corresponding to the search word, and storage means for storing the search word, search word identifier, voice information, and the like. have. Here, the voice information providing means may use a TTS (Tex-To-Speech) technology for converting text into voice, and may be more easily operated by VXML (Voice XML) technology. Since the TTS technology and the VMXL technology are obvious to those skilled in the art, detailed descriptions thereof will be omitted, and it will be apparent that the voice conversion technology, which is developed in the future, may be equally applicable.

3A is a functional block diagram illustrating a configuration according to a function of a number management apparatus according to an exemplary embodiment of the present invention, and FIG. 3B is a diagram illustrating a reserved word table stored in the number management apparatus according to an exemplary embodiment of the present invention. to be.

Referring to FIG. 3A, the number management device 70 includes a receiver 71, a storage unit 72, a character recognition unit 73, an extraction unit 74, an interlocking unit 75, and a transmitter 76. .

The receiving unit 71 performs a function of receiving caller information transmitted from the calling terminal 10 and calling terminal information capable of recognizing the calling terminal 10 from the switch 30 or the location register 50. In addition, since it is apparent that arbitrary data can be received from a specific device, a detailed description thereof will be omitted.

The storage unit 72 performs a function of storing one or more character strings, a called number corresponding to the character strings, and a search term identifier for a search word in response to information about each registered subscriber (information providing terminal). A separate area is provided for each subscriber to store a character string and a called number corresponding to the character string. Accordingly, the number management device 70 may extract the called number of the information providing terminal 90 corresponding to the character string received and recognized from the calling terminal 10.

Referring to FIG. 3B, the storage unit 72 stores the reserved word table 80. The reserved word table stores a reserved word, a URL or a phone number of an information providing terminal corresponding to each reserved word, and a search word identifier corresponding to each search word and the search word. For example, when the number management device 70 receives 'Search * Egypt' as the called party information from the calling terminal 10, the number management device 70 extracts 02-1111-2222 * 1100 and transmits it to the exchange. In this case, the search term identifier is provided in the form of a numeric string that can be processed by the mobile communication network. If the mobile communication network can process the string later, the search word may be transmitted as it is without converting (or mapping) the search word identifier. .

Here, in another embodiment, the information providing terminal 90 accesses or connects to the information providing terminal 90 through a corresponding URL (URL), if the called number or search word and the search term identifier are not stored in advance, or TCP / IP. By defining a separate protocol such as a keyword and providing a search word, a called number and a search word identifier corresponding to the search word may be received. For example, in case of obtaining caller ID and search term identifier through UAL, "Search * Egypt" requests the corresponding information to NAVER's corresponding terminal through ' www.naver.com/mobsearch.asp?id = Egypt' can do.

That is, the number management device 70 does not store the called number of each information providing terminal 90, but may provide it to the exchange as it receives the called number from the information providing terminal 90 in real time. The number management device 70 recognizes the information providing terminal 90 corresponding to the received character string, and receives the called number from the information providing terminal 90 in response to requesting the called number from the recognized information providing terminal 90. Can be. In addition, the number management device 70 receives a search term identifier (in the form of a number) corresponding to the search word as it transmits the search word when the called party number is requested.

Referring again to FIG. 3A, when the character string 73 receives the character string from the calling terminal 10, the character recognizer 73 performs a function of recognizing a character string corresponding to the character string. Typically, the character input method is determined according to the company manufacturing the terminal. Therefore, in order to recognize a character string corresponding to the character string, the character input method of the calling terminal 10 should be known. As a way of knowing the text input method of the calling terminal 10, information on the model of the calling terminal 10 is used. The model information may be received together with the called party information according to a call request of the calling terminal 10 from the location register 50 or the exchange 30 that recognizes a character string, and may be registered in advance by a user or may be received in advance from the location register 50. It may be received and stored in the storage unit 72 as outgoing subscriber information. Accordingly, the character recognition unit 73 may recognize a character string corresponding to the character string and the model information.

Here, the model information of the terminal is not necessarily received from the location register 50, there is a separate subscription information management server for managing the subscription information of each terminal, from the subscription information management server in advance or in real time model information of the terminal Can also be obtained. Alternatively, without the type information of the calling terminal 10, a character input method is set in advance, and each terminal transmits a number string corresponding to a character input through the set character input method to the mobile communication network, and receives the received number management device. 70 may recognize the character string according to the preset character input method.

The extraction unit 74 performs a function of extracting, from the storage unit 72, a destination number corresponding to the character string received by the reception unit 71 (or a character string recognized by the character recognition unit) and a search term identifier corresponding to the search word. do.

The interlocking unit 75 performs a function of obtaining the corresponding information in association with the corresponding information providing terminal 90 when the called number and the search term identifier are not stored. That is, a called number and a search term identifier are obtained from the information providing terminal 90 through the address of the information providing terminal 90 stored in the storage unit 72.

Therefore, the called number and the search term identifier may be received from the information providing terminal 90 in real time, and may be registered and stored in advance.

The transmitter 76 transmits the called number and search term identifier extracted or acquired by the extractor 74 or the linker 75 to the switch 30 via the location register 50. Of course, it can also be sent directly to the exchange 30. In addition, since it is apparent that arbitrary data can be transmitted to a specific device, a detailed description thereof will be omitted.

Hereinafter, the overall procedure of the voice call service for information retrieval using the called party information of the present invention will be described.

4 is a diagram schematically illustrating the overall procedure of a voice call service for searching for information using called party information according to an embodiment of the present invention. In particular, with reference to Figure 4 will be described taking the case of transmitting the alphanumeric string as the receiver information.

According to FIG. 4, in step S410, the calling terminal 10 transmits a call request signal including called party information including an alphanumeric string and identification information to the exchange. In step S415, the exchange 30 recognizes that the received called party information is not a general phone number or the called party information and calling terminal information (for example, a phone number or a terminal identification number) to the location register 50 through the service identification information. Send it. In step S420, the location register 50 recognizes the service through the service identification information, and in step S425 requests the called number by transmitting the character string and the calling terminal information to the number management device (70).

In step S430, the number management device 70 recognizes the character string corresponding to the character string and extracts the called number corresponding to the character string. As described above, the called number may be extracted from the reserved word table 80 stored in the number management device 70, or may be received in real time from the information providing terminal 90. In addition, when a search word is included in the string, a search term identifier for the corresponding search word is extracted. As described above, the search word identifier may be stored in the reserved word table 80 or may be received from the information providing terminal 90 in real time according to a request.

When the search term identifier is received from the information providing terminal 90, the information providing terminal 90 stores information (eg, a phone number) of the corresponding calling terminal 10. Thereafter, when a call is received from a terminal that matches the stored information, the corresponding search term identifier may be matched with a search word, and voice information corresponding to the matched search word is extracted and provided.

Alternatively, the information providing terminal 90 stores the search word, the search term identifier and the called number together, recognizes the terminal connected to the called number, extracts a search word corresponding to the search term identifier, and provides corresponding voice information. . Here, the information providing terminal 90 owns a plurality of called numbers to be provided to the number management device 70, selects and transmits one of them, and stores the received called number in association with the search word and the search term identifier. Therefore, a search word corresponding to the calling terminal 10 to be connected later may be recognized.

 In step S435, the number management device 70 provides the extracted called number to the location register 50, and in step S440, the location register 50 transmits the called number to the switch 30, thereby switching 30 in step S445. ) Establishes a call for a voice call between the calling terminal 10 and the information providing terminal 90 through the corresponding called number.

Here, when the calling terminal 10 transmits a character string other than an alphanumeric string as the called party information, if the exchange 30 can recognize that the character string is a string, the exchange 30 immediately transmits the number without passing through the location register 50. By transmitting the character string to the management device 70, the called party number may be received to set up a call for a voice call.

5 is a diagram illustrating an operation process for an information retrieval voice call service using character strings of a number management device and an information providing terminal according to an embodiment of the present invention.

According to FIG. 5, in step S510, the number management device 70 receives the called party information from the switch 30 or the location register 50. In step S515, the number management device 70 recognizes the character string of the called party information.
