Description

Apparatus and method for providing neighboring information based regional unit retrieval system with video phone, and method for providing the service of looking up the phone number in neighboring districts to calling customers}

The present invention relates to a local information service apparatus and method using a local unit search service in a video telephone environment, and to a telephone connection service system and method using the same. When dialing a local service access number (for example, '** 114'), an Internet video phone can display a variety of menu-selective phonebook images using the local search closest to the caller's location or the caller's location. The present invention relates to a local information service apparatus and a method thereof, and a telephone connection service system using the same, and a method for enabling a caller to make a call by finding a desired incoming call number.

In the present invention, 'local information service' is provided by recognizing DTMF (Dual Tone Multi Frequency) tones transmitted from a video telephone and searching for local information closest to a location of a caller or a location selected by the caller. This means that the searched local information is menuized (that is, processed into a menu-selective phone book image) to be provided to the video telephone so that the caller can select and connect the local information.

Therefore, the menu-selective phonebook image has a regional information (eg, Great Wall, Seocho-gu Office, Seocho Library, etc.) based on the caller's location (eg, Seocho-gu). ), And when selecting any local information (that is, when you want to make a phone call from a single menu or upper / lower menu), the local information business (for example, Great Wall Restaurant, Seocho-gu Office, Seocho Library, etc.) It is configured to be able to dial immediately. In addition, the 'menu selectable phone book image' may be provided together with the announcement. To do this, it is produced as VoiceXML (Voice Extensible Markup Language) document for executing location-based local information service script.

The menu-selective phone book image is provided with local information step by step by the caller. For example, a menu-selectable phone book image including category information is initially provided, and then the location information is determined according to the caller's menu selection (category selection). A menu-selective phonebook image is provided that includes based on the local information [may be provided one-stop until this step], and then a menu-selective phonebook image of the local information is provided according to the caller's menu selection [the single menu or The upper / lower menu is shown in this step], and then the caller can be configured to make a call to the called phone number according to the caller's phone call selection.

Therefore, the menu selection phone book image of the local information, the menu information of the local information consists of a single menu such as address, business name, telephone number, brief information, whether the telephone connection, or the upper menu information of the local information, It consists of business name, phone number, brief information, call connection status, and detailed information including submenu information of the local information including upper menu information (for example, address, business name, phone number, short information, and restaurant advertisement (public information). , Recommendation menu, directions, call connection, previous menu connection, etc.) can be organized hierarchically.

In addition, in the present invention, 'video phone' is not only a video phone without a wired / wireless internet application client, but also a video phone with a wired / wireless internet application client. Call '** 114') to generate DTMF tones by receiving a menu-selective phonebook image (including VoiceXML document) on the screen and generate DTMF tones to select and dial the desired phone number of the local business. It is sufficient if it is a 'terminal in a telephone environment (video or voice call) with a video display that can be connected'. Therefore, it should be noted that the 'video telephone' targeted in the present invention is irrelevant to whether the wired / wireless internet application client is mounted.

There is no wired / wireless internet application client in the current video telephone.

As such, a case of providing a location-based service in a video telephone environment in which a wired / wireless internet application client does not exist is shown, using a general telephone using DTMF tones, a national representative telephone service (for example, flower delivery (1588-3927) ) Calls from the region closest to the location of the caller making the call via chicken (1588-9299), Chinese cuisine (1588-6690), moving / cargo transportation (1588-1224), and packaging director (1588-3824). I am using a method of connecting points (near routing). As such, the 'National Representative Number Telephone Service' combines the phone numbers used by each branch or institution by government agencies, media companies, and large corporations that have multiple workplaces in the country. This service connects you to the nearest branch or agency.

However, in the case of using the national representative telephone service, the caller is required to memorize at least the national representative number for each service (for example, 1588-3927, 1588-9299, 1588-6690, 1588-1224, etc.). In particular, it is more difficult to find a telephone number operated by a small business without a national representative number [in this case, using a yellow page]. Also, when a customer ordering food calls for a nearby and famous restaurant, the customer is trying to find a restaurant phone number because the location-based search is not a menu-selective phonebook of local information. In the case of obtaining a phone number through a Yarrow page or a leaflet], or by calling a restaurant phone number already known to order food, it can be said that the choice of restaurants is narrow.

Although customers have recently been provided with local information services through mobile communication terminals or PDAs, this is only possible in special environments where Internet application clients are provided. However, in the process of receiving location-based local information through a mobile communication terminal or PDA equipped with an Internet application client, the information is obtained by text input (keyword search) through a wireless Internet connection. Time delays occur and the procedures are complex, making them ineffective for people who are not used to the Internet (eg, the elderly). In addition, since the provided local information is not a menu-selective phone book type, the user cannot easily select the desired information.

In addition, even in the process of receiving local information through a PC or laptop equipped with an Internet application client, the information is obtained by text input (keyword search) through a wired Internet connection, which causes a great delay in obtaining information. (Eg delays in system boot time and Internet access attempts on PCs or laptops), and the process is complex and ineffective for people who are not used to the Internet (eg, the elderly). In addition, since the accuracy of the person who is not used to the Internet to find a phone number using location-based information is less accurate, the user may encounter unwanted information [for example, the restaurant 'the Great Wall' Information about China's Great Wall. Even if you get the local information you want, you can't make a direct phone call to the local business. Therefore, a separate telephone (wireless or wireless telephone, mobile phone, etc.) must be used for the telephone connection.

However, above all, in order to receive local information service through a terminal (mobile phone, PDA, PC, laptop, etc.) equipped with an Internet application client, it is possible only in an environment in which wired and wireless Internet access is possible.

Therefore, even if the wired / wireless internet application client is installed, there is a problem in that it is impossible to connect the wired / wireless internet (for example, a shaded area, a moving area, etc.), or location-based local information service is not possible in the terminal that is not equipped with the wired / wireless internet application client.

Therefore, regardless of whether there is a wired / wireless internet application client, by recognizing the DTMF tone transmitted from the videophone of the calling customer in the videophone environment, providing a menu-selective phonebook image through location-based local information retrieval, the caller wants the incoming call. It is an object of the present invention to make an incoming call easily without having to memorize the phone number while viewing the menu-selective phone book image of the phone number.

Therefore, the present invention provides a method of making a call when an Internet video telephone subscriber dials a location-based local information service access number (for example, '** 114') in a video telephone environment, with or without a wired or wireless Internet application client. To display various menu-selective phonebook images on the internet videophone screen using the local search closest to the caller's location or the location selected by the caller, so that callers can find and call the desired forwarding phone number. An object of the present invention is to provide a local information service apparatus and a method thereof, a telephone connection service system using the same, and a method thereof.

The above objects, features, and advantages will become more apparent from the detailed description given hereinafter with reference to the accompanying drawings, and accordingly, those skilled in the art to which the present invention pertains may share the technical idea of the present invention. It will be easy to implement. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of an embodiment of a local information service and telephone connection service system according to the present invention.

The present invention can be largely divided into a service configuration that services local information based on location, and based on this.

First, referring to the configuration of the local information service device, when the local information service request from the video telephone 10, the service switching device 20 for recognizing and triggering the service identification number and the service triggered session start request message is analyzed and located After checking the information (for example, the same code), the service control device 30 requesting the local information service and the location information corresponding to the current location of the caller or the location selected by the caller are searched to the service control device 30. Transmitting the location information providing device 40 and a message requesting the VoiceXML document for executing the location information and local information service script, interprets the received VoiceXML document in response to the menu-selected phonebook image in real time transmission protocol ( RTP) is provided to the video phone 10, and the menu selection signal book of the local information by recognizing the menu selection signal The media control device 50 for providing a video to a video telephone and the media control device 50 according to the request, construct a menu-selectable phonebook image with local information based on the location information, respond to the voiceXML document, and select a menu. And a local information providing apparatus 60 which responds by loading a menu-selectable phonebook image of the corresponding local information in a VoiceXML document.

The menu-selective phonebook image can be divided into 'menu-selective phonebook image composed of location information based on location information' provided in the previous step of menu selection and 'menu-selectable phonebook image of relevant local information' provided after menu selection. Can be. Hereinafter, the 'menu selection' refers to an act of inputting a menu number of a caller to obtain a 'menu selection phonebook image of the corresponding local information'.

In the above, the menu selection phone book image of the local information is composed of a single menu, and can provide a call forwarding function and a call connection function to the corresponding phone number in the corresponding menu. In this case, the sender selects one of the category information (e.g., 'Gourmet', 'Public Office', 'Sightseeing', etc.) and again selects the sender's location or Local information considering the location selected by the caller (for example, 'Great Wall', 'Unusual King's Foot', etc.). [Menu-selective phonebook image composed of local information based on location information provided in the previous step of menu selection. , Up to this step may be provided as a one-stop] (for example, 'the Great Wall') (select menu), and then again select the telephone connection menu number in the local information (telephone connection selection).

Alternatively, the menu selection type phonebook image of the local information may include a brief information of the local information as the upper menu, and the detailed information of the local information is configured in the lower menu. At least one may provide an incoming call phone number and a call connection function to the corresponding phone number. In this case, the sender selects one of the category information (e.g., 'Gourmet', 'Public Office', 'Sightseeing', etc.), and again selects the sender's location or Local information considering the location selected by the caller (for example, 'Seocho-gu Office', 'Seocho Police Station', etc.) [A menu-selective phonebook image consisting of local information based on location information provided in the previous step of menu selection, Up to this step may be provided as a one-stop] (e.g., 'Seocho-gu') (ie, select the first menu) and then back to the sub-menu of the local information (for example, 'Seocho-gu') (E.g., 'Complaint') and then select a dial-up menu number (i.e., make a call) from the submenu (e.g., 'Complaint'). .

In the above-described menu selection step, only category information may be provided and then location-based area information corresponding to a category selected by the caller may be provided, or location-based area information together with category information may be provided as one-stop. Therefore, it should be noted that the menu selection type phonebook image composed of local information based on location information provided in the previous step of menu selection assumes both of the above cases. Then, the menu-selective phonebook image of the local information is the caller's first menu in the menu-selective phonebook image (multiple local information based on location) consisting of local information based on location information provided in the previous step of menu selection. According to the selection (including the second menu selection), the detailed information of the corresponding local information is provided. Subsequently, the phone connection can be selected in the menu selection phone book image of the corresponding local information.

Therefore, the 'menu-selective phonebook image composed of local information based on location information' provided in the previous step of menu selection includes a menu-selective phonebook image composed of each local information based on location information according to category selection. It consists of minimal information (address, business name, etc.) that can recognize each area information.

In addition, the session initiation request message essentially includes the telephone number and IP address of the video telephone, and optionally further includes a postal code input by the caller. However, the location information providing device 40 checks the search request message received from the service control device 30 and, if there is a postal code, searches for the same code using the postal code as the highest priority search key.

Therefore, the location information may be the same code based on the telephone number of the video telephone 10 or the IP address of the video telephone 10. In this case, the location information providing device 40 makes a database of (telephone number, IP address), (telephone number, same code), (IP address, same code), and searches received from the service control device 30. Extract the phone number from the request message to search for (phone number, IP address), and check whether the retrieved IP address (first IP address) exists on the same subnet as the IP address (second IP address) included in the search request message. If it is not in the same subnet, search for the code by using the second IP address as the search key, and if it is in the same subnet, search for the code by using the telephone number or the first IP address or the second IP address as the search key. do.

In addition, the location information may be the same code based on the postal code. In this case, the location information providing apparatus 40 extracts a postal code from a search request message received from the service control device 30 by making a (postal code, location information) into a database, and then uses the postal code as a search key. Search for the code.

On the other hand, the telephone connection service system, in the local information service device, the media control device 50 recognizes the telephone connection selection signal (final incoming connection telephone number selection signal) received from the video telephone 10 and accordingly incoming Obtain a connection telephone number, request call routing control to the incoming connection telephone number, and under the control of the service control device 30, the service switching device 20 routes the call to the incoming connection telephone number, thereby making a call between callers / called parties. The connection is possible. At this time, the media control device 50 forms a conversation in the form of a VoiceXML document request and a VoiceXML document response through the local information providing device 60 and HTTP, and the caller's incoming call number selected by the caller from the local information providing device 60. The incoming call phone number is obtained through a VoiceXML document (which is a VoiceXML document including the incoming call phone number).

The function of each component of the local information service device having the configuration and features as described above and the telephone connection service system using the same will now be described in detail.

Although the video telephone 10 is equipped with a wired / wireless internet application client as well as a terminal not equipped with a wired / wireless internet application client, the location-based local information service access number (for example, '**' 114 ') to generate a DTMF tone, and receive a menu-selective phone book image on the screen to generate DTMF tones to select the incoming call number of the local business and to connect the phone. It is sufficient if it is a terminal of a telephone environment (video or voice call) provided.

As described above, the 'menu-selective phonebook image composed of local information based on location information' provided in the previous step of menu selection includes a menu-selective phonebook image composed of respective regional information by category selection, It is desirable to consist of minimal information (address, business name, etc.) that can recognize local information.

In addition, the menu selection phone book image of the local information, the detailed information of the local information (for example, the Great Wall, Seocho-gu office, Seocho library, etc.) based on the caller's location (for example, 'Seocho-gu') menu type ( Single menu or upper / lower menu). In particular, the "sender's location" may be the 'sender's current location (same as the video phone's current location)' [in this case, retrieving location information (e.g., the same code) based on the phone number and IP address). ] Or "the location of the region chosen by the caller at random." [This is the case where the caller inputs a postal code, which gives priority to the location information search by giving the postal code to the location information (e.g. )].

As an example of the menu-selective phone book image of the local information, the menu information of the local information may be configured as a single menu such as an address, a business name, a telephone number, a brief information, and a telephone connection. As another example, the upper menu information of the local information may be configured with an address, a business name, a phone number, a brief information, and a telephone connection, and the lower menu information of the local information may include detailed information including the upper menu information (for example, an address, Business name, phone number, brief information, restaurant advertisement (public information), recommendation menu, directions, telephone connection, previous menu connection, etc. can be hierarchically organized. However, in the single menu or the upper / lower menu of the menu selection phonebook image of the local information, it is possible to immediately call (video or voice call) to the telephone number of the local information business.

In addition, in consideration of the screen size of the video phone 10, the menu selection type phone book image is "category information → government office information (for example, based on the caller's location or the location selected by the caller, such as Seocho-gu office, Seocho police station, etc.) ) → Upper menu information (eg, Seocho-gu office information according to menu selection) → Lower menu information (eg, complaints and information according to menu selection) → Submenu information (eg, call connection information according to telephone connection selection) It is desirable to have a subdivided menu hierarchy such as). "

As described above, each region information based on category information and location may be separated and integrated.

As such, the telephony connection may be configured to be selectable from a single menu, upper and lower menus, or lower menus, and the configuration of menu information may be variably configured.

The menu-selective phonebook image is transmitted in a VoiceXML document for executing a location-based local information service script, and provides an environment for accessing the local information providing apparatus 60 based on a telephone.

Looking at the configuration of the video telephone 10 with reference to Figure 2, a menu processing unit 11 for processing various types of telephone function setting menu desired by the customer, and a number input unit having an input key for location-based local information service ( 13) and the announcement of the menu-selective phonebook image (VoiceXML document), the handset 12 (including the speakerphone) for making a voice call with the other party through the video phone 10, and the menu-selective phonebook image. , A display unit 14 for making a video call with the other party through the video phone 10, and a network connection unit 15 for connecting the video phone 10 to the wired or wireless Internet.

In particular, the video telephone 10 sessions when a customer (sender) requests a location-based local information service by calling a location-based local information service access number (for example, '** 114') (DTMF tone generation). Generate a start request message.

At this time, the session start request message includes the telephone number and IP address of the outgoing video telephone 10. In this case, DB (phone number, IP address) is searched based on the phone number, and if the searched IP address exists in the same subnet as the IP address in the session initiation request message, the location information (eg , The same code), and if it does not exist in the same subnet, the location information (e.g., the same code) is searched by IP address.

In addition, in addition to the telephone number and IP address of the calling terminal, the session initiation request message may further include a postal code, which means that the customer (sender) requests a location-based local information service for an arbitrary area other than his current location. This is the case. For example, the caller is currently located in 'Seoul Seocho-gu' but wants to receive location-based local information service for 'Seoul Gwanak-gu'. In this case, priority is given to the postal code, and the positional information (e.g., the same code) is retrieved. To this end, the video telephone 10 should be provided with a postal code input unit 110 for inputting a postal code in addition to the telephone function setting menu of the menu processing unit 11.

Accordingly, as shown in FIG. 3, the header of the session initiation request message includes a calling customer telephone number, a calling client video telephone IP address, and a zip code entered by the calling client as values for location-based local information service. Add the fields "TEL URL", "IP ADDRESS" and "ZIP CODE".

When the customer (sender) requests the location-based local information service using the video telephone 10, the service switching device 20 recognizes the service identification number (for example, ** 114) to the service control device 30. Trigger.

After checking the location-based local information service request, the service control device 30 analyzes the session start request message received from the videophone 10 (see FIG. 3), and uses the search information on the phone number, IP address, and zip code as a search key. The location information (eg, the same code) is retrieved from the providing device 40 to request a local information service, and when a final incoming connection telephone number is selected by the caller, the caller is in charge of call control. A more detailed operation process of the service control device 30 will be described later with reference to FIG. 7.

The location information providing device 40 transmits the caller's location information as the same code value by using a postal code, a phone number, and an IP address, which may be location information, as a search key. At this time, the location information providing device 40 has a database of (postal code, same code), (telephone number, IP address), (telephone number, same code), (IP address, same code) information, and service control. Respond to a query request from the device 30. A detailed operation process of the location information providing apparatus 40 will be described later with reference to FIG. 8.

The media controller 50 receives the session control request message from the service controller 30 (at this time, transmits the session control response message from the media controller 50 to the service controller 30, and the service controller ( 30, the session initiation response message is transmitted to the video telephone 10 through the service switching device 20, and the video telephone 10 starts the session to the service control device 30 through the service switching device 20. Transmitting the confirmation message, and transmitting the session control confirmation message from the service control device 30 to the media control device 50], and supports the interaction between the videophone 10 and the local information providing device 60. In other words, it plays a role in relaying service information through functions such as interpretation and execution of VoiceXML documents, media conversion, real-time transmission protocol (RTP) generation, and DTMF detection for interaction with the sender. A detailed configuration of the media control device 50 and an operation process thereof will be described later with reference to FIGS. 4 (including FIGS. 5 and 6) and FIG. 9.

The local information providing apparatus 60 retrieves the local information based on the same code according to the caller's location (or according to the caller's location selected) received from the media controller 50, and then selects a menu-selective phone book image and the final incoming call. Provide a connection number. A more detailed operation process of the local information providing device 60 will be described later with reference to FIG. 10.

Then, with reference to the configuration of Figure 1, a brief description will be given of the service procedure for servicing the local information based on the location of the caller or the location selected by the caller and telephone connection based on the location information.

First, when a customer (sender) requests a service by pressing a location-based local information service access number (for example, ** 114) to the video phone 10, the service switching device 20 recognizes the service identification number and controls the service. Service triggers to device 30.

Subsequently, the service controller 30 analyzes the session start request message [see FIG. 3] received through the service triggering of the service exchange apparatus 20, and then includes a zip code, a phone number, and an IP address, which can be location information. Request the same code value to the location information providing apparatus 40 as a search key. On the other hand, the location information providing device 40 finds the same code using a zip code, a phone number, and an IP address, which may be location information, as a search key, and transmits the same code to the service control device 30. At this time, for a flexible local information service (for local information service by selecting an arbitrary region of a caller), priority is given to a zip code search key to find the same code value. This assumes that the current caller's location is different from the location to receive location-based local information service. Of course, if there is no postal code, the local information service is provided based on the current location of the sender.

As described above, the session initiation request message may include a telephone number and an IP address, and additionally a postal code. If a postal code exists, priority is given to the postal code and location information according to the postal code ( Code). However, if the postal code does not exist, check the movement of the subnet based on the IP address, and if it exists in the same subnet, search for location information (eg, the same code) according to the telephone number (or IP address), If it does not exist, the location information (e.g., the same code) according to the IP address is retrieved.

Therefore, the location information providing device 40 transmits the same code value corresponding to the location of the caller or the location selected by the caller to the service control device 30 as a response message.

Then, the service control device 30 is a voice code value received from the location information providing device 40 to request a location-based local information service and VoiceXML document URL (that is, VoiceXML for executing the code-based local information service script) Document URL) in the session control request message and transmitted to the media control device 50. Subsequently, when the media controller 50 receives the session control request message from the service controller 30, the media controller 50 extracts the same code value and the VoiceXML document URL, and then the same code-based local information service script (location-based local information service script). In order to execute), the same code value and VoiceXML document URL are transmitted to the local information providing apparatus 60 using the Hyper Text Transport Protocol (HTTP). That is, a request message of HTTP is created with the same code and the VoiceXML document URL value, and a VoiceXML document is requested to the local information providing apparatus 60.

Next, the local information providing apparatus 70 receives and analyzes a message requesting a copper code value and a VoiceXML document through HTTP, and then responds by putting a menu-selective phonebook image on the VoiceXML document for executing a location-based local information service script. A message (VoiceXML document) is transmitted to the media controller 50 to prepare for interaction with the media controller 50 for the code-based local information service.

Subsequently, when the media controller 50 receives the VoiceXML document (including the menu-selective phonebook image), the media control device interprets the VoiceXML document, which is a location-based local information service script, and renders the announcement broadcast to the customer (sender). And the video file (menu-selective phone book image) is converted into a real-time transmission protocol (RTP) and transferred to the video phone (10).

Subsequently, a customer (caller) who wants to find a call forwarding phone number to make a call through the menu-selective phone book image and the announcement broadcast played on the videophone 10 through a real-time transmission protocol (RTP), viewing the menu image. Pressing the number, the media control device 50 receives the menu number through the real-time transmission protocol (RTP) through the voiceXML script interaction process of the final destination menu number of the local information service desired by the caller through the DTMF signal extraction process Deliver to local information providing device (60). In response to this, the local information providing apparatus 60 transmits the final corresponding VoiceXML document of the advertisement image, the incoming call number, the connection status, the previous menu connection, etc., to the final destination menu number determined by the caller through the HTTP protocol. 50, and the media controller 50 transmits it to the video telephone 10.

Through this process, the media controller 50 interprets and executes the final VoiceXML document based on the last called menu number received from the caller, and sends a session control request message to which the last called phone number is added. To pass). Then, the service control device 30 receiving the session control request message transmits the session start request message to the service switching device 20 to detect the final incoming call number and attempt to generate a new call. 20), the caller makes a call (video or voice call) to the last incoming call number found through the location-based local information service.

Therefore, the caller can directly connect by selecting a phone number that he / she wants to call from the local information close to his location or the location of his selected area through the menu-selective phone book image.

Referring to FIG. 4, the configuration of the media control apparatus 50 for the local information service will be described. Under the control of the controller 52 and the controller 52, the service controller 30 may control the local information service.

The session control request message with the incoming call number as the delivery value when extracting the same code value and the VoiceXML document URL, and the customer (sender) sees the menu-selective phonebook image and selects the final menu number (selection of call connection). To the service control device 30.

The local information providing apparatus connection unit 54 requests a VoiceXML document to the local information providing apparatus 60 by creating an HTTP request message with the copper code and the VoiceXML document URL value in order to execute the same code based local information service script. In response, the voiceXML document (including the menu-selectable phonebook image) is received and transmitted to the VoiceXML processing unit 53 through the control unit 52.

The VoiceXML processing unit 53 stores a sound source file (that is, a voice or audio signal as a result of rendering the VoiceXML document) and an image file (menu-selectable phonebook image) that are analyzed and rendered by the VoiceXML document sent by the local information providing apparatus 60. Save to 55.

The storage 55 temporarily stores a sound source file generated by the VoiceXML processor 53 and an image file (ie, a menu-selectable phone book image) received in response to HTTP from the local information providing apparatus 60.

The image processor 56 converts a sound source file and an image file (menu-selectable phonebook image) stored in the storage 55 into a media transmission format and transmits the image file to the video phone 10, and the menu number pressed by the caller from the video phone 10. Receives (menu selection signal, telephone connection selection signal, etc.) through the real-time transmission protocol (RTP) detects the DTMF message and converts it into a form that can be recognized by the VoiceXML processing unit 53 and notifies the control unit 52. .

The video telephone connection unit 57 is responsible for a series of processes related to the interaction between the video processing unit 56 and the video telephone 10.

The controller 52 is responsible for a series of interactions related to the interaction between the video phone 10, the local information providing device 60, and the service control device 30 to provide location-based local information service by controlling each component. .

Referring to FIG. 5, referring to the configuration of the VoiceXML processing unit 53 for a local information service, the local information providing device 60 receives the data from the local information providing device 60 while performing HTTP communication with the local information providing device 60 through HTTP.

It is further provided with a function of converting the data into the present form.

7 is a flowchart illustrating a message control procedure in the service control apparatus of FIG. 1 in a local information service and a telephone connection service system according to the present invention.

First, when a customer (sender) requests a service by pressing a location-based local information service access number (for example, ** 114) to the video phone 10, the service switching device 20 recognizes the service identification number and controls the service. Service triggering to device 30, service control device 30 receives a session start request message from service switching device 20 via service triggering (701).

Thereafter, the service control device 30 extracts a postal code, a phone number, and an IP address related to the location information of the originating customer from the session start request message (702) and generates a search request message using the search key (703). At this time, the session initiation request message essentially includes the telephone number and IP address of the outgoing video telephone 10, but the postal code is optionally further included according to the caller's input action.

Thereafter, the service control apparatus 30 transmits the generated search request message to the location information providing apparatus 40 (704), and receives the same code result value (705). At this time, the location information providing device 40 finds the same code by using a zip code, a phone number, and an IP address which can be location information. [At this time, if a zip code exists, priority is given to the zip code search key. To find the same code] and transmits to the service control device (30).

Next, the service controller 30 generates a session control request message to which the same code result value and VoiceXML document URL information (that is, URL information of the VoiceXML document for executing the code-based local information service script) are added to the media. The control device 50 transmits the data to the control device 50 (706).

Thereafter, the media controller 50 interprets and executes the final VoiceXML document based on the last called menu number received from the caller, and transmits the session control request message to which the last called phone number is added to the service controller 30. do.

Therefore, when the service control device 30 receives the session control request message in which the final call forwarding phone number information selected by the customer (sender) is selected from the media control device 50 (707), a new call is generated to the called phone soon. A session initiation request message is generated and transmitted to the service switching apparatus 20 (708).

Thereafter, the service controller 30 monitors an event such as an incoming response or an abandon call from the originating / incoming telephone with respect to the session initiation request message for generating a new call (709), and compares the call termination event with a processing routine. Act 710. At this time, until the call termination event occurs, the event of the incoming / outgoing telephone is continuously monitored.

If the call termination event is received from the calling / incoming telephone, the call is normally terminated (711).

FIG. 8 is a flowchart illustrating a message control procedure in the location information providing apparatus of FIG. 1 in a local information service and a telephone connection service system according to the present invention.

The location information providing device 40 is a service control device by preliminarily making a database of (postal code, same code) (telephone number, IP address), (telephone number, same code), and (IP address, same code) information. 30) it is waiting for a query request (801 ~ 803).

If the search request message for the postal code, telephone number, and IP address information is received from the service control device 30 (704), the location information providing apparatus 40 checks whether the postal code exists in the search request message ( 805). As described above, when the caller's current location and the location to receive location-based local information service are different, the caller may select an arbitrary area through a zip code. Therefore, if a postal code exists in the search request message (805), the location information providing device 40 is for the flexible local information service (for local information service by the caller's arbitrary area selection), the postal code search key Priority is given to find the same code value (806), the retrieved code is carried in the response message to the service control device 30 to transmit (811).

However, if the postal code does not exist in the search request message (805), the phone number is extracted from the search request message and the information is retrieved (telephone number, IP address) so that the searched IP address is the same as the IP address in the search request message. Check if it exists in the subnet (808).

If the check result 808 does not exist in the same subnet, the video telephone 10 has moved the location, so that the same code is searched for the received IP address (the IP address included in the search request message) (810). The code is carried in the response message and transmitted to the service controller 30 (811).

As a result of the check 808, if it exists in the same subnet, since the video telephone 10 did not move the position (movement within the subnet range corresponds to its category), the same code is searched by the received telephone number (809). In step 811, the retrieved same code is loaded into the response message to the service controller 30. Of course, if it is present in the same subnet, it is preferable to search for the code by the received telephone number, but searching the code by the IP address can yield the same result.

As such, the location information providing device 40 generates a response message to which the retrieved copper code value is added and transmits the response message to the service control device (811).

9 is a flowchart illustrating a message control procedure of the media control apparatus of FIG. 1 in a local information service and a telephone connection service system according to the present invention.

As described above, the service controller 30 loads the same code value and VoiceXML document URL received from the location information providing apparatus 40 in the session control request message to request the location-based local information service. To send).

Therefore, when the session control request message is received from the service control device 30 (901), the media control device 50 extracts the same code and VoiceXML document URL information from the session control request message (902), In order to execute the local information service script, the same code value and VoiceXML document URL are transmitted to the local information providing apparatus 60 using HTTP (904). That is, a request for a VoiceXML document is made by creating an HTTP request message with the same code and the value of the VoiceXML document URL and transmitting the same to the local information providing apparatus 60.

Subsequently, when a VoiceXML document, which is a local information service script, is received in response to the HTTP request message from the local information providing apparatus 60 (905), the media controller 50 parses, interprets, and executes the received VoiceXML document ( In operation 907, the generated image file (menu-selectable phonebook image) and the sound source file are stored in the storage 55.

Next, the media controller 50 reads the sound source and the image file stored in the storage 55, converts it into a real-time transmission protocol (RTP), and transmits it to the videophone 10 (step 908).

Then, when the menu-selective phonebook image and the announcement broadcast transmitted through the real-time transmission protocol (RTP) are delivered to the caller, the media controller 50 relays the interaction between the caller and the local information providing apparatus 60 ( 909). That is, the caller who wants to find the call forwarding phone number to make a call presses the menu number through the menu-selective phone book image and the announcement broadcast played on the video phone 10 through a real-time transmission protocol (RTP). After receiving the menu number through the real-time transmission protocol (RTP), the media control device 50 receives the final destination menu number of the local information service desired by the caller through the DTMF signal extraction process and the voice information through the VoiceXML script interaction process. Delivering to the providing device 60, the local information providing device 60 for the final destination destination menu number determined by the caller, the final corresponding VoiceXML document about the advertisement image, incoming call phone number, connection status, previous menu connection, etc. It transmits to the media controller 50 via the HTTP protocol, and the media controller 50 interprets the VoiceXML document to select a menu. The phone book image (in this case, the detailed menu image corresponding to the menu number selected by the caller among the previously transmitted menu images) and the sound source file are transmitted to the video phone 10.

This relay process 909 is repeatedly performed until the caller presses a menu number at which the menu-selectable phonebook image selection process can be completed and receives the final VoiceXML document from the local information providing apparatus 60 (910). In other words, if the final VoiceXML document is not received, the step continues to receive the menu number from the sender. This assumes that the telephone connection is in the final VoiceXML document (sub menu). However, as mentioned above, it should be noted that the telephone connection may be provided in both the upper and lower menus or only in the lower menu.

If the caller presses a menu number (eg, makes a desired final call connection) at which the menu-selective phonebook image selection process can be terminated, the media controller 50 determines the last called telephone number of the corresponding VoiceXML document. Is obtained from the local information providing apparatus 60, and transmits a session control request message to the service control apparatus 30 to which the final incoming connection telephone number is added (911).

FIG. 10 is a flowchart illustrating a message control procedure of a region information providing apparatus of a region information providing apparatus of a region information service and a telephone connection service system according to the present invention.

The media controller 50 transmits the code value and the VoiceXML document URL to the local information providing device 60 using HTTP to execute the code-based local information service script. [HTTP request message = Request for VoiceXML document. Message].

Therefore, when an HTTP request message written with the same code and VoiceXML document URL value is received from the media controller 50 (101), the local information providing apparatus 60 sends the same code as a search key to the sender as a response to the HTTP request message. A menu-selective phonebook image for a local information service is created and loaded on a VoiceXML document and transmitted to the media controller 50 through HTTP (102).

Thereafter, the local information providing apparatus 60 forms a conversation in the form of a VoiceXML document request and a VoiceXML document response in HTTP in the local information service script (103). That is, the menu selection phone book image of the corresponding local information according to the menu selection is provided. Therefore, when the menu is hierarchically configured, the upper menu information is provided in step 102, but the lower menu information of the corresponding local information selected by the caller is provided in step 103.

If there is a menu number selected for the final call forwarding phone number during the conversation process (104), and if the result of the verification is a menu number for continuing the conversation process, the VoiceXML document request and the VoiceXML document in HTTP in the local service script The conversation is formed in response (103). That is, through the dialogue, such as "category information → upper menu information (for example, government office information based on the caller's location or the location selected by the caller) → lower menu information (for example, complaints and information) → call connection information", and the like. You will use a granular menu hierarchy.

If the check result 104 indicates that there is a menu number selected for the final call forwarding number during the conversation processing, the voiceXML document including the final call forwarding number retrieved after searching for the last forwarding call number searched based on the same code is mediated. The controller 50 transmits to the control device 50 (105).

11 is a flowchart illustrating an embodiment of a method for providing a local information service and a telephone connection service according to the present invention.

First, a customer (sender) sends a session initiation request message (see FIG. 3) to request a service by pressing a location-based local information service access number (for example, ** 114) to the videophone 10. ), The service switching device 20 recognizes the service identification number in the session start request message and triggers the service to the service control device 30 (112). At this time, the session initiation request message essentially includes the telephone number and IP address of the video telephone 10, which may be location information, and the caller for a local information service (fluid local information service) by selecting an arbitrary region of the caller. Optionally, the postal code entered is further included.

Subsequently, the service control device 30 analyzes the session start request message received through the service triggering from the service switching device 20, and then stores the same code value and the local information service collected through the location information providing device 40. In operation 113, the session control request message in which VoiceXML document URL information is added to the media controller 50 is requested.

Here, the location information providing apparatus has priority in the postal code if the postal code exists in the search request message (telephone number, IP address is essentially included, and the postal code is optionally further included) received from the service control device 30. Search for location information (code) based on the postal code, and if the postal code does not exist, check the movement of the subnet based on the IP address. If it does not exist in the same subnet, the code is searched according to the IP address.

When the session control request message (including the code value and VoiceXML document URL information) is received from the service controller 30 as described above, the media controller 50 transmits the session control response message to the service controller 30. 114, the service control device 30 receives the session initiation response message to the service switching device 20 (115), and the service switching device 20 receives the session initiation response message to the video telephone ( 10) (116).

Thereafter, the video telephone 10 transmits the session start confirmation message to the service switching device 20 (117), and the service switch device 20 receiving the received message transmits the session start confirmation message to the service control device 30. In operation 118, the service controller 30 receiving the message transmits the session control confirmation message to the media controller 50 (119).

When the session control check procedure is performed between the media controller 50 and the video telephone 10 as described above, the media controller 50 receives the same code value and VoiceXML document in the session control request message received from the service controller 30. After extracting the URL, a voiceXML document request message is transmitted to the local information providing apparatus 60 by using the HTTP code value and the VoiceXML document URL as a parameter to execute the same code based local information service script (120). . In response to this, the local information providing apparatus 60 retrieves the caller's location or information of the region desired by the caller based on the same code, generates the voiceXML document, and transmits the voiceXML document response message to the media controller 50 (121). ). That is, a menu-selected phonebook image is loaded on a VoiceXML document for execution of a location-based local information service script, and an HTTP response message is transmitted to the media control device 50, and the media control device 50 for the local information service based on the same code is provided. Prepare for the interaction.

Subsequently, when the media controller 50 receives an HTTP response message (VoiceXML document including a menu-selectable phonebook image), the media controller 50 generates a real-time transmission protocol to display an image phonebook screen (menu-selectable phonebook image) and guide broadcast (sound source) of the local information service. File) to the videophone 10, and the caller responds to the number selected in the menu-selective phonebook image with the number input button of the videophone 10 (DTMF tone generation), so that the information is transmitted through the real-time transmission protocol. It is transmitted 122 to the media controller 50 in DTMF format. At this time, the media control device 50 analyzes and extracts the DTMF format received by the real-time transmission protocol, and sends the VoiceXML document request message using HTTP again using the menu number inputted by the sender as a local information providing device ( 60), and the local information providing apparatus receives the voiceXML document response message to the media controller 50 (123).

That is, when the media controller 50 receives the VoiceXML document, the media controller 50 interprets the VoiceXML document, which is a location-based local information service script, and transmits a sound file and an image file (menu-selective phone book image) that renders the announcement broadcast to the caller in real time. Protocol (RTP) is converted and transmitted to the video phone (10). And, through the real-time transmission protocol (RTP) through the menu-selective phone book image and the announcement broadcast played on the video phone 10, the caller who wants to find the incoming connection telephone number to make a call presses the menu number while viewing the menu image. , The media control device 50 receiving the menu number through the real-time transmission protocol (RTP) provides the local information through VoiceXML script interaction process of the final destination menu number of the local information service desired by the caller through the DTMF signal extraction process. To the device 60. In response to this, the local information providing apparatus 60 transmits the final corresponding VoiceXML document of the advertisement image, the incoming call number, the connection status, the previous menu connection, etc., to the final destination menu number determined by the caller through the HTTP protocol. 50, and the media controller 50 transmits it to the video telephone 10.

In this way, the caller proceeds to step "122" and "123" to look for the menu-selective phonebook image and finds the final call forwarding number. The media controller 50 uses the real-time transmission protocol to advertise the final destination to the caller. At the same time (124) and transmits the session control request message with the last incoming call number as a parameter to the service control device 30 (125), the service control device 30 receives the received media control device ( Send a session control response message to step 50).

Thereafter, the service controller 30 transmits the session initiation request message received from the media controller 50 to the service exchanger 20 (127), and the service exchanger 20 receives the session initiation request message. Is transmitted to the telephone (called telephone) of the final destination (128).

The destination telephone then transmits the session initiation in progress message to the service control device 30 via the service switching device 20 (129, 130) for the session initiation request message, and the recipient receives the call (hookoff ( Hook-off)], the session initiation response message is transmitted to the service control device 30 via the service switching device 20 (131, 132).

Next, the service controller 30 receiving the session initiation response message transmits the session initiation re-request message to the service exchanger 20 (133), and the service exchanger 20 receiving the session initiation re-request is received. When the message is transmitted to the caller's videophone 10 (134), the session start response message is transmitted from the caller's videophone 10 to the service switching device 20 (135), and the service switching device 20 receiving the message is received. Transmits the session start response message to the service controller 30 (136).

Accordingly, the service control device 30 transmits the session start confirmation message to the caller's video phone 10 via the service switching device 20 with respect to the session start response message from the caller video phone 10 (137, 138). In response to the session start response message of the called phone, the session start acknowledgment message is transmitted to the called phone via the service switching device 20 (139 and 140).

Through this process, a direct call connection is made between the caller / caller through a real-time transmission protocol (141).
