SYSTEM AND METHOD FOR PROVIDING REALTIME CUSTOM-MADE INFORMATION OF TOURIST RESORT}

The present invention relates to a system and method for providing real-time personalized information for tourist attractions, and more specifically, real-time personalized information for tourist attractions that provides customized information consistent with the tourist purpose of tourists and continuously provides differentiated tourist information and advertisement information. A provisioning system and method are provided.

It is no exaggeration to say that tourism has become part of life in response to the expansion of the transportation network such as the aviation network. Accordingly, each country is making efforts to develop and promote tourist attractions that are closely related to the national interests of each country, and also devote a large amount of costs to each region in order to develop and promote tourist attractions in Korea.

Although tourist attractions are introduced through the broadcasting network and online, they are still informed about the surrounding area through flyers related to advertisements such as restaurants and lodging places as well as flyers related to tourism. However, it is practically impossible to announce all the information of tourist attractions through such flyers, and most of these flyers are related to advertisements of tourist attractions. Accordingly, in order to effectively perform such advertisements, a booklet may be issued and provided to tourists. However, these booklets must reflect the changed contents according to the changes of the advertisers who wish to advertise, so the process of reprinting and the like must be repeated many times. In other words, advertising through flyers in tourist attractions not only causes waste of paper space, but also causes confusion for tourists due to information floods.

In order to compensate for such a problem, a method of receiving an advertisement through online and advertising the advertisement in accordance with the contract condition has been proposed. An exemplary method would be commercials over the public network or the Internet. However, commercial broadcasting has a disadvantage in that it takes a lot of cost, and there is a limitation that commercial broadcasting cannot be performed in real time in connection with the movement of tourists. In order to compensate for this, a method of providing tourist information and advertisement information in real time by using a mobile communication terminal or a navigation which most of tourists possess is proposed. However, this scheme also provides only comprehensive information about tourist attractions, and has limitations in providing customized information required by tourists.

On the other hand, virtually any point may be a destination for tourism, but in the case of relatively wide tourist sites such as islands with well-equipped transportation networks and leisure facilities, most of the systems are built to rent cars, motorcycles and other means of transportation. Doing. In particular, automobiles provide navigation guides and location information by installing navigation, as well as advertising information on tourist attractions and surrounding facilities based on location. However, tourism information and advertisement information through the navigation is only information of a brief introduction degree, there is also a problem that can not provide substantially any information when visiting a tourist destination of a specific location away from the car.

As such, there is a need for a plan that can provide customized tourist information for tourist attractions and advertisement information in tourist attractions, and the need to continuously differentiate and deliver tourist information and advertisement information in response to the movement of tourists. It is becoming.

Accordingly, the present invention has been made to solve the above problems of the prior art, the object of the present invention is to organize tourist information and advertising information to provide customized information to tourists on the basis of tourist specific information and tourism purpose information In response to the movement of tourists, real-time tourist information and advertisement information is simplified or detailed for each tourist area to provide different information, and real-time personalized information for tourist attractions that allow coupons, etc. related to advertisement, to be used in the target facilities.

Although not shown, a questionnaire terminal for databaseing the questionnaire of the tourist is connected to the tourism relay server 30, and a plurality of related terminals such as an advertisement producer, a tourist wisher, a tour relay server 30 manager, and the like are connected. . Meanwhile, in the present embodiment, the configuration for one tourist destination is disclosed, but a general management server for collectively managing the tourism relay server 30 may be separately provided to collectively manage a plurality of tourist attractions.

The repeater 40 delivers the tourist information and advertisement information transmitted from the tourism relay server 30 to the access point 50, and stores the location information and unique ID information of all the access points 50. Performs a relay role of transmitting the location of the tourist terminal 60 to the tourist relay server (30).

The access point 50 detects the approach of the tourist terminal 60 and transmits and receives a wireless communication signal, and is arranged in a plurality of tourist spots, and is densely arranged in a tourist spot that many tourists visit among tourist spots. That is, the access point 50 refers to a node constituting the network. The access point 50 performs a function of storing tourist information and advertisement information transmitted from the tourism relay server 30 to deliver tourist information and advertisement information in real time. It is preferable to use a night with relatively few network operations for delivering tourist information and advertising information. In response to the request of the adjacent tourist terminal 60, the stored tourist information and advertisement information may be provided in real time.

The tourist terminal 60 receives tourist information and advertisement information, temporarily stores coupons issued among the advertisement information, and performs handoff by checking the received signal strength of the access point 50. The tourist terminal 60 communicates via cellular telephones, smartphones, laptops, personal computers, handheld communication devices, handheld computing devices, satellite radios, Global Positioning Systems (GPS), personal digital assistants (PDAs), and wireless networks. Any one of any other suitable device may be used.

The operation process by the configuration of the real-time customized information providing system for tourist attractions is as follows. The advertiser accesses the website opened by the tourism relay server 30 using the advertiser terminal 10 and transmits the contract related to the advertisement relay and the produced advertisement information to the tourism relay server 30, and thus the tourism relay server ( 30) organizes the advertisement so that the advertisement information and tourist attractions publicity to the tourist terminal 60 in accordance with the contract conditions. In this state, the tourist provides information on the unique number of the tourist terminal 60, tourist information, tourist purpose, etc. through the tourist terminal 60 rental shop or questionnaire terminal provided at the airport, bus or taxi stand, tourist attraction entrance, etc. If so, the data is transmitted to the tourism relay server (30). The tourism relay server 30 continuously provides real-time customized information and differentiated tourist information and advertisement information of the present invention in response to the movement of the tourist terminal 60 of the tourist.

2 is a control circuit block diagram of the tourism relay server according to an embodiment of the present invention.

As shown in Figure 2, the tourism relay server 30 of the present invention is always connected to the Internet 20 through the router 301, the security server 302, the system manager 303, the web server (304), billing authentication server 305, mail server 306, database (DB) server 307, storage (Storage) server 308, file conversion server 309, file transfer server 310, FTP A server 311 and a backup server 312 are included.

The tourism relay server 30 operates the website according to the above-described configuration, receives advertisement information by the advertiser, receives various contents, authenticates personal information of advertisers and tourists, schedules based on tourist information, tourists' Support various multimedia file formats according to the type of tourism terminal 60, self-converting for intelligent data transmission, management, and security, compression and automatic conversion of files such as tourist information and advertisement information, content data using real time or idle time It performs automatic transmission and update, real time management of node failure, management of transmission data for tourists, various billing management, and self-security backup function.

Here, look at the role of each server of the tourism relay server 30 in more detail as follows.

The system manager 303 is connected to each server to manage and operate each server.

The web server 304 performs a function for providing the online accessor through a website about tour guide information, geographic information, tourist attractions, and the like.

The database server 307 accumulates various types of tourist information such as key features, locations, facilities, and floating populations for tourist destinations to select tourist destinations in response to real-time search of tourists. Save billing details. In addition, it supports version management of content that is updated from time to time, the update cycle of content and complementary work of content, and performs functions such as information management of tourists and a marketing support system for analyzing tourist tendencies.

The file conversion server 309 automatically converts and processes the tourism information and the tourism information into a standard format that is predefined so that each tourist terminal 60 can be displayed without difficulty. For example, if a moving picture is defined to be executed in the MPEG2 format on the display panel of the tourist terminal 60, it performs a function of converting the tourist information and tourism information into the MPEG2 format. At this time, the file conversion server 309 of the tourism relay server 30 performs a function of automatically converting and processing the different tourist attractions and tourism information of the tourism terminal 60 in accordance with a prescribed format and then storing the information itself.

The file transfer server 310 stores the tourist information and the tourism information of the tourist terminal 60 automatically converted and processed, and when the transmission request signal is received from the repeater 40, the file transfer server 310 transmits the corresponding tourist information and the tourism information to the corresponding tourist terminal 60. It performs the function of sending to).

On the other hand, the server that is not described is a simple description of the normal function will be omitted.

3 is a conceptual diagram of a real-time video relay system according to an embodiment of the present invention.

As shown in FIG. 3, in order to construct a real-time video relay system of the present invention, a network camera 70 is installed in a tourist spot and a tourist facility, and the network camera 70 accesses an image captured in real time by an access point. Transfer to the tourism relay server 30 via the (50). The tourism relay server 30 transmits the image captured in real time to the tourism terminal 60 through the relay and the access point 50 'by operating a database server, a file conversion server, and a file transfer server. In response, the tourist terminal 60 may check the tourist destination or the tourist facility in real time in response to a user request.

In addition, when a tourist takes a video and transmits it to the tourist relay server 30 via the access point 50 ", the tourist passes the video to the tourist terminal 60 through the above process.

On the other hand, for the efficiency of network operation, real-time video performs the real-time processing, and tourist information and advertising information that is taken in advance and fixedly stored in response to the request of the tourist terminal by storing the tourism information and advertising information in the access point In the access point 50 ′, it is desirable to deliver the pre-stored tourist information and advertisement information. At this time, since it matches with the access point (50, 50 ") provided in the photographed location, the video information may be stored in the access point (50, 50") to which the video is delivered.

In addition, the video taken by the network camera and the tourist is a tourism terminal that has a request through communication between the access points (50 → 50 ', 50 "→ 50') without going through the tourism relay server to increase network efficiency. 60) can also directly deliver the real-time video.

This includes the status of the product currently being advertised, real-time video broadcasting of the sales office, real-time video broadcasting of the tourist spots that tourists are sightseeing, real-time video broadcasting of the tourists eating at the restaurant, and menus currently on sale in the restaurant (including food making process). It can be used for real-time video broadcasting, tourist reviews and video reviews.

4 is a conceptual diagram of a network installed in the main part of the tourist destination according to an embodiment of the present invention.

As shown in FIG. 4, the network installed in the main part of the tourist destination includes a plurality of access points 501 to 504, which access wireless communication signals of the tourist terminals 601 to 605. It may be fixed, mobile, wireless, Wi-Fi, etc. in one or more sectors receiving, transmitting, relaying.

At this time, the access points 501-504 can communicate with each other as needed, and data transmission on the forward link can be performed at or near the maximum data rate that can be supported by the communication system or the forward link. 504 to a tourist terminal 601-605. Additional channels (eg, control channels) of the forward link are transmitted from multiple access points 501-504 to the tourist terminals 601-605. The reverse link data transmission is made from the tourism terminals 601-605 to one or more access points 501-504. In addition, in the case of an ad hoc network, the reverse link communication is routed by using another tourist terminal 603 through its own tourist terminal 604 to 605. Accordingly, the other tourist terminal 603 may serve as an access point.

Meanwhile, since the present invention is applied to a tourist destination, a plurality of tourist terminals 601 to 605 may be connected to the access points 501 to 504. In this case, since a large amount of data may be downloaded to the tourism terminals 601 to 605 through the access points 501 to 504, an efficient method of downloading is required. To this end, a master-slave relationship between neighbor nodes may be defined as a transmission / reception relationship to improve data processing performance of transmission and reception by using a scheduling protocol. This will be described in detail with reference to FIG. 7.

Since the real-time customized information providing system for tourist attractions configured as described above can be operated in various ways, it will be described for providing tourist information and advertisement information using a removable navigation attached to the rental car for convenience of description. . Of course, the method of operating this system includes all system operation methods that can be inferred by those skilled in the art.

As described above, in the present embodiment, the navigation is used as a guide for the destination in the road network as usual, and when the user leaves the rental car and moves to a specific tourist destination, the navigation is removed so that the tourist information and advertisement information can be provided.

This navigation is provided to tourists in the form of rentals, and it is desirable to have a system for tourists to rent near tourist attractions. For example, it is preferable to arrange a navigation and rental at an airport, a railway station, a high-speed bus terminal, or to arrange and rent a navigation at a hotel, a lodging place, or to arrange a navigation at the entrance of a tourist destination. In addition, the operator operating the tourism relay server 30 may be directly rented.

Next, the method for providing real-time customized information for tourist attractions of the present invention using the system configured as described above will be described.

5 is a flowchart illustrating a method for providing real-time customized information for tourist attractions according to an embodiment of the present invention.

As shown in FIG. 5, the tourism relay server 30 has a database of information for promoting tourist attractions by the manager (S10). In this state, an advertiser wishing to engage in an industry related to tourism in a tourist destination requests an advertisement to the tourism relay server 30 through the Internet 20 (S20). The tourism relay server 30 receives the advertiser information and the location information together with the advertisement request and organizes the advertisement in the advertisement (S30).

Upon arrival at the tourist spot, the tourist requests a rental car at a rental car rental shop and requests navigation rental (S40). In response to the rental, the tourists will provide their own details and answer necessary documents and questionnaires such as rental conditions. In this case, the rental of the rental car and the navigation is preferably automated, and the personal details are preferably provided using a questionnaire terminal or navigation. Accordingly, the tourist information input by the tourist is transmitted to the tourism relay server 30 (S50).

The tourism relay server 30 organizes the personalized information based on the information of the tourist. First, when the tourist selects a specific destination, the tourist server and the target facility in the road network from the current location to the specific destination are selected from the database server. Read and organize tourist information and advertisement information corresponding to the location of tourists.If a specific destination is not selected, various types of tourism methods such as rest, sports, hiking, and sea bathing are selected to respond to the selected tourism method. Prepare and organize tourist information and advertising information (S60). Of course, it is desirable to provide a variety of contents for tourists to select a variety of forms of tourism, it is preferable to make such a tourism method to be selected through navigation.

Therefore, tourists attach navigation to the rental car to receive various contents including geographic information contents, tourism contents, shopping contents, and interpreters.They are tailored to the tourist's purpose in response to providing tourist information through navigation. Information will be provided for navigation.

In this case, the usage history according to the content provision may be added to the rental fee to be settled later, or the usage history may be delivered to the tourist mobile terminal in real time.

As the content is used in the navigation as described above, the fee is calculated according to the corresponding usage history, and tourists often receive tourist information and advertisement information corresponding to the location of the corresponding area while moving through the road network. That is, when using the geographic information content of the navigation (S70), the tourism relay server 30 receives the GPS signal and continuously records the location of the tourist. In addition, the list of advertisers (or companies that requested advertisements) within a certain distance from the place where the tourists are located is searched to automatically display the advertisement contents of the advertisers in the navigation (S80). When the tourist selects a specific line item from among the displayed advertisers, the tourist relay server 30 requests the details of the advertisement, and the tourism relay server 30 searches the detailed advertisement contents of the database and transmits them to the navigation. Detailed advertisement contents related to the corresponding advertisement contents are displayed. Subsequently, the tourism relay server 30 calculates a wireless communication time for receiving the detailed advertisement, calculates a communication fee based on the calculated time, and imposes a communication fee for the advertisement upon the advertiser. In this way, records of the movement path and the use of the content are accumulated and databased (S90).

In the case of the advertising method of the present invention, the rental fee of the navigation can be reduced or exempted from the advertising fee received from the advertiser, and also a part of the sales revenue of the facility by directly connecting the location where the tourist is currently located and the local facility in real time. It is possible to adopt a method of reducing the cost to tourists.

On the other hand, when moving out of the road network by walking or walking, the tourist removes the navigation to continue to receive information that is helpful for tourism, and also to receive information that guides the movement route.

A process of transmitting information of a tourist destination in correspondence with a navigation location will be described in detail below.

6 is a flowchart illustrating a real-time video relaying process according to an embodiment of the present invention.

As shown in Figure 6, the access point is always connected to the advertisement relay server to maintain the reception standby state (S81). At this time, when a tourist terminal is connected and a real-time video request is received from the corresponding tourist terminal, the real-time captured video is transmitted to the tourist terminal. The tourist relay server transmits the access point and the requested video to the tourist terminal. The access point is searched and the video stored in the access point to which the video is transmitted is transferred to the access point to which the tourist terminal is connected (S82).

On the other hand, if it is determined that the number of tourist terminals connected to the access point is less than or equal to the set value (S83), the access point requests to download the video captured in its communication area (S84). The tourism relay server determines whether there is an uploaded video and returns to the standby state if there is no newly uploaded video, and if there is an uploaded video, delivers the video to the access point (S85). The transferred video is stored (S86). In this case, if the delivered and stored video is a video relating to a tourist facility, the video is stored for a predetermined period of time and transmitted to the tourist terminal in response to the request, and the number of times delivered to the tourist terminal is counted (S87). In this counting, tourist attractions are associated with advertising costs, and tourist attractions are used as references in relation to popularity.

7 is a flowchart illustrating an operation process of a scheduler applied to an access point and a tourist terminal according to an embodiment of the present invention.

Since the present invention is applied to a tourist destination, a large number of tourists tend to gather. In order to deliver tourist information and advertisement information in real time to many tourists, it is desirable to apply a scheduling technique.

First, a method for performing sender-based scheduling and receiver-based scheduling is illustrated, which method is sender-based in an FDMA environment, an OFDMA environment, a CDMA environment, a WCDMA environment, a TDMA environment, an SDMA environment, or any other suitable wireless environment. Includes both scheduling and receiver-based scheduling. For convenience of explanation, the operation process will be described through one embodiment, but the present invention is not limited thereto.

As shown in FIG. 7, a dynamic decision on whether to use a sender-based data packet scheduling technique or a receiver-based data packet scheduling technique is performed depending on a plurality of scheduling factors. That is, the scheduling factor is analyzed and evaluated to evaluate resource occupancy at each transmitting node and receiving node (S801). For example, the scheduling factor may include weights associated with nodes to which data packets are sent, physical distances between nodes, traffic mix between nodes (eg, data traffic, control signal traffic, paging signals, etc.), neighbors. Interference caused by the node, and the like. A determination is made as to whether the transmitting node should schedule a data packet for transmission (eg, sender based scheduling) or whether the receiving node should schedule transmission of a data packet (receiver based scheduling) (S802).

The sender-based scheduling protocol includes, for example, a sender node that advertises that there is a data packet that needs to be scheduled for transmission to the recipient node (eg, via a paging channel). The receiver node then responds to the sender node with an indication that the receiver node is ready to receive the data packet. The sender node selects one or more channels or subcarriers and sends data packets to the receiver node.

The receiver-based scheduling protocol includes, for example, a sender node that sends a request to send a data packet to a receiver node. The receiver node thus sends a grant to the sender node indicating one or more channels or subcarriers from which the sender node may send data packets. Based on the analysis of the scheduling factor, the transmitting node and the receiving node execute either of the receiver-based scheduling protocol or the sender-based scheduling protocol (S803). As such, dynamic determination of relative measures of congestion at the transmitting and receiving nodes is made, thereby facilitating the selection of an efficient scheduling protocol.

Then, with the selected protocol running, whether the transmission is mainly download-oriented or mainly upload-oriented (e.g., if the amount of download data is greater than the amount of upload data or if the amount of upload data is greater than the amount of download data). A lot)) (S804). If it is determined that the download amount is larger than the upload amount, the receiver-based scheduling protocol is executed to schedule transmission of the data packet (S805). If the download amount is less than or equal to the upload amount, a sender-based scheduling protocol is executed to schedule transmission of the data packet (S806). If the download portion and the upload portion of the data are the same, either of these scheduling protocols is used. If the data transmission includes the same download portion and upload portion, one scheduling protocol or another scheduling protocol is designated as the preferred protocol. Thereafter, the data packet is terminated after the data packet is scheduled according to the selected protocol. In order to provide dynamic scheduling of transmissions, the process returns to step S801 for further repetition (eg, analysis of scheduling factors, feature transmissions, and protocol selection for additional data packets).

This process is used to ensure that nodes in the network operate under sender-based scheduling or receiver-based scheduling. Sender-based scheduling or receiver-based scheduling is performed in a static manner. In addition, a dynamic decision is made as to whether sender-based scheduling or receiver-based scheduling is to be performed at any given point in time.

Dynamic determination may, for example, be based on a large time scale, for example wired access point 50 is set up to use server-based scheduling as a default. Dynamic determination may be based on a relatively small time scale, for example, the wireless access point 50 acting as the repeater 40 performs a time division protocol between server-based scheduling and receiver-based scheduling. In addition, server-based scheduling is used as the default mode in some nodes.

As described above, in the state where the transmitter-based scheduling or the receiver-based scheduling in the tourism terminal 60 is performed, the transmitter-based scheduling or the receiver-based scheduling is also performed in the access point 50.

Under “receiver based” scheduling, the access point 50 sends a request to the tourism terminal 60, which need not be carried out via a separate transmission, but between the access point 50 and the tourism terminal 60. Is embedded in the packet at If the tourist terminal 60 has sufficient resources (eg, subcarrier or code), the tourist terminal 60 grants the access point 50 a permission indicating which channel the access point 50 may transmit. Send. Under “sender-based” scheduling, the access point 50 advertises to the tourist terminal 60 that a data packet is present (eg, via a paging channel). The tourism terminal 60 responds and notifies the access point 50 that the tourism terminal 60 is ready to receive a packet. The access point 50 then transmits the packet over the channel selected by the access point 50 (e.g., subcarrier set, time slot, code signature, ...).

As such, there is a need to dynamically schedule data packet transmissions based on the number of connections at the node involved in the data transmission. The node may have a current data transmission, and there is a need to determine whether the node should schedule the current data transmission (eg, as a sender node) or ask the recipient node to schedule this data transmission. This compares the ratio of the incoming connection to the outgoing connection (for example, whether the number of received signals is greater than the number of transmitted signals) (S807). If the number of incoming connections is greater than the number of outgoing connections, a receiver-based scheduling protocol is executed to schedule the transmission of data packets. If the number of incoming connections is less than the number of outgoing connections, a sender-based scheduling protocol is executed to schedule transmission of data packets (S808 to S809). If the number of incoming connections and the number of outgoing connections are the same, either of these scheduling protocols is used. If the data transmission includes the same download portion and upload portion, one scheduling protocol is designated as the preferred protocol. Thereafter, the data packet ends after the data packet is scheduled according to the selected protocol. In order to provide dynamic scheduling of transmissions, the process returns to step S801 for further repetition (eg, analysis of scheduling factors, feature transmissions, and protocol selection for additional data packets).

This process is used to ensure that nodes in the network operate under sender-based scheduling or receiver-based scheduling. Sender-based scheduling or receiver-based scheduling is performed in a static manner. At any given point in time, a dynamic decision is made as to whether sender-based scheduling or receiver-based scheduling is to be performed. Dynamic decisions are based on large time scales, for example. For example, wired access point 50 is set up to use a server-based scheduling protocol as a default. Dynamic decisions are based on relatively small time scales. For example, the wireless access point 50 acting as the repeater 40 performs a time division protocol between the server-based scheduling protocol and the receiver-based scheduling protocol. Server-based scheduling is used as the default technique in some nodes.

In this way, the tourist terminal 60 and the access point 50 are provided with a sender-based scheduler and a receiver-based scheduler in each device to perform the functions shown in FIG. It is possible to respond to the requirements of tourists in real time by constructing a system that can easily provide information. In particular, it may be easily applied to an environment in which specific data of a tourist destination needs to be transmitted as a large file such as a video. Through this, the effect of advertisement can be maximized, which will be closely related to the operating profit of nearby facilities as well as maximizing the delivery power of tourist attractions.

After that, tourists who return the tour will return the rental car and navigation. If you pay the additional cost for using the contents of the navigation, all the tours will be completed. It manages to visit a number of tourist sites by carrying out management or by continuously providing tourists with information on seasonal tourism.
