Description

System refreshing content using user's location information and content taste, and method

The present invention relates to a contents delivery network (hereinafter referred to as a 'CDN') service, and more particularly, to a content refresh system and method utilizing a content selection preference based on location information and location information of a user on a CDN. will be.

The international network that forms the interworking of various local and wide area networks (WAN) around the world is called the Internet. The Internet can be infinitely extended by interworking through communication media, and supports the smooth exchange of information by connecting networks with each other. In recent years, the subscriber network between a network operator called an Internet Service Provider (ISP) and a web user has been replaced by an asymmetrical or symmetrical digital line. As the bandwidth available to the user increases, there is an increasing demand for more content services. More content services, in turn, require advancement of communication networks. A content user who wants to provide a content service accesses a content server provided by a content provider and downloads desired content. In this case, as the network moves between ISP networks, the network becomes overloaded and bottlenecks occur, which causes delays or frequent disconnections.

Various efforts have been made to solve the above problems and to improve speed on the Internet. For example, an ISP (Internet Service Provider) may expand a backbone network called a back-bone. However, the purpose is to smoothly handle traffic within individual networks, which is not effective due to the increase in data transmission rate, which is more than doubled.

As a second example, an improvement in the speed of the Internet can be achieved through the improvement of the subscriber network section from the backbone network called Last-Mile to the home or business. However, it is difficult to expect an improvement in the speed of the Internet because investment has not been made in the link between the backbone network and the backbone network called Middel-Mile or the backbone network and the subscriber network.

An alternative to solve the problem is a content delivery network (CDN). The CDN does not improve the connection between the backbone network and the subscriber network by expanding the physical network, but rather by distributing the data traffic, that is, the bottleneck, to the main points of the Internet network.

The client 10 is a comprehensive concept of devices including wired and wireless terminals such as various types of PCs, PDAs, laptops, and mobile terminals, which receive information from a server connected to a conventional mobile terminal or a network such as the Internet.

The client 10 of the present invention may make a request to the web server 70 for a content including a web page and an embedded object, and in response thereto or directly from the web server 70. Can be sent indirectly. The client 10 may also be composed of clients located in other zones, such as client A 11 located in the first zone and client B 15 located in the second zone. Here, although the client A 11 and the client B 15 are illustrated as one client in the drawing, it is apparent that the client A 11 and the client B 15 can be configured by a plurality of clients in each zone.

Meanwhile, although not shown, the client 10 may include a browser and a resolver. When a Uniform Resource Locator (URL) for requesting specific content is input into the browser of the client 10, a resolver connected to the browser accesses a local name server (not shown) registered in advance. It converts the domain name into the IP address of the web server 70 providing the content.

Meanwhile, the proxy server 30 receives the content from the web server 70 and delivers the content to the client 10. In detail, the proxy server 30 may include a proxy server DB 31, a controller 33, and an analyzer 40.

The proxy server DB 31 may include the selective content request signal {first zone selective content request signal Sig_Select1), the second zone selective content request signal Sig_Seclect2, generated by the analysis unit 40, hereinafter, the selective content request signal for each zone. Receive and store the optional content matched according to the " first zone selective content (Data_Select1), the second zone selective content (Data_Select2), hereinafter, " selective content for each zone " from the web server 70. .

In summary, the proxy server DB 31 according to the present invention generates the selective content request signals Sig_Select1 and Sig_Select2 for each zone according to the category of each zone, and generates the selective content (Data_Select1, Data_Select2) for each zone that matches the zone. Save it.

Meanwhile, in the present specification, the DB may mean a functional structural combination of software and hardware for storing information corresponding to each DB. The DB may be implemented as at least one table, and may further include a separate DBMS (Database Management System) for searching, storing and managing the information stored in the DB. In addition, it may be implemented in various ways such as linked-list, tree, relational DB, and includes all data storage media and data structures capable of storing information corresponding to the DB.

The controller 33 may include the location information DB 35.

The location information DB 35 stores the location information of the clients 11, 15, ... for each zone. Specifically, the location information DB 35 determines which zones (eg, the first zone, the second zone, ...) are the clients 11, 15, ... for each zone. Saving. On the other hand, in the present invention, the region divided by the location is expressed as 'zone,' it is not limited to terms such as region, earth (地區).

In one embodiment of the present invention, the control unit 33 may determine that the first zone according to the pre-stored location information for the client A (11) when the search information request from the client A (11).

The control unit 33 receives a request for search information for each zone from the clients 11, 15, ... together with the analysis unit 40, and grasps the zones of the clients 11, 15, ... as described above. To generate zone information. Meanwhile, in the present specification, 'search information request' may be a request for corresponding content using search information.

More specifically, the control unit 33 stores the content corresponding to the request for the search information of the client (client A 11, client B 15, ...) for each zone in the zone previously stored in the proxy server DB 31. Whether it is included in the optional content (Date_Select1, Data_Select2) according to the determined zone.

As a result of the determination, when the content corresponding to the search information requested by the client of each zone (client A, client B) is matched with the optional content of each zone (Data_Select1, Data_Select2), the control unit 33 is connected to the web server 70. It is possible to transmit the selective content (Data_Select1, Data_Select2) for each zone corresponding to the search information request directly to the clients of each zone (Client A, Client B) without going through.

According to an embodiment of the present invention, when the client A 11 of the first zone requests the search information matching the first zone selective content Data_Select1, the controller 33 requests the client to select the first zone selective content Data_Select1. The A 11 can be directly transmitted without making a request to the web server 70.

The analysis unit 40 receives a search information request from each client of each zone (client A 11 and client B 15) in real time to generate a comprehensive analysis table, and counts the number of search information requests for each zone and counts them. Search information whose number of times is greater than or equal to a threshold may be extracted for each zone.

The analysis unit 40 may generate the selective request signals Sig_Select1 and Sig_Select2 according to the zones using the search information extracted for each zone and transmit the generated request signals to the web server 70. Accordingly, the web server 70 stores the optional contents (Data_Select1, Data_Select2) according to the zone among the integrated service contents stored in advance in the proxy server 30, more specifically, the DB for each zone created in the proxy server DB 31. (1st zone DB 31A, 2nd zone DB 31B, ...) can be matched and transmitted.

Meanwhile, referring to FIG. 2, the analysis unit 40 may be described in more detail. The analysis unit 40 may include an analysis unit DB 41, an analysis module 43, and a content management module 45. Meanwhile, in the specification, a module may mean a functional and structural combination of hardware for performing the technical idea of the present invention and software for driving the hardware. For example, the module may mean a logical unit of a predetermined code and a hardware resource for performing the predetermined code, and means a physically connected code or does not necessarily mean one kind of hardware. It can be easily inferred by the average expert in the art.

The analysis unit DB 41 receives and stores a search information request, more specifically, a term corresponding to a search information request from clients of each zone (client A 11, client B 15, ...). . In addition, the analysis unit DB 41 may store a comprehensive analysis table generated by the analysis module 43 to be described later.

The analysis module 43 receives the search information request stored according to each zone from the analysis unit DB 41 individually, and counts the number of search information requests according to each zone to collect information on the number of search times for a predetermined period of time. can do. The collected information may be extracted for each zone separately from a preset threshold.

In another embodiment of the present invention, the analysis module 43 divides the search results counted based on each request for search information by area into a search time indicating a predetermined period, thereby obtaining a comprehensive analysis table by deriving an average value. Can be generated. The comprehensive analysis table generated in the above manner may be generated as shown in Table 1 below.

First Zone Client Second Zone Client Search information umbrella ratio rose acid dry Dirt humidifier Air cleaning Search count 30 times 15th 55 times 5 times 15th 20 times 11th 70 times Search time 2 hours 2 hours 2 hours 2 hours 1 hours 1 hours 1 hours 1 hours Average value (count / minute) 0.25 0.125 0.46 0.04 0.25 0.33 0.18 1.17 ranking 2 3 One 4 3 2 4 One

On the other hand, the analysis module 43 may extract, by zone, the search information more than a predetermined threshold for the number of searches (or average value) of the comprehensive analysis table generated as shown in Table 1. For example, if the analysis module 43 sets the threshold value to "0.1", the analysis module 43 is "Umbrella" which is the search information for the client A 11 of the first zone of the average value of 0.2 or more in Table 1 above. Search information for can be extracted. In addition, the analysis module 43 may extract search information about "dry" and "dust" which are search information for the client B 15 of the second zone.

In one embodiment of the present invention, the Popularity approach may be used as a method used for replicating all or a part of the integrated service content stored in the web server 70.

The content management module 45 selects the optional contents (Data_Select1, Data_Select2) for each zone among the integrated service contents stored in the web server DB 71 for storing in the proxy server DB 31 based on the comprehensive analysis table generated for each zone. Optional content request signals Sig_Select1 and Sig_Select2 for each zone for requesting may be generated.

The content management module 45 may transmit the generated selective content request signals Sig_Select1 and Sig_Select2 to each web server 70.

The network 50 refers to a data communication network for data transmission and information exchange between the client 10, the proxy server 30, and the web server 70. In the figure, although the network 50 is shown as a wired network, it is well known that the network 50 may be configured as a wireless network. On the other hand, the wireless network may include a base station (Node-B), a base station controller (RNC), switch (MSC, SGSN), home location register (HLR).

The web server 70 provides the contents directly to the clients 11 and 15 for each zone requesting the download of the web page and the optional contents for each zone (Data_Select1 and Data_Select2) or through the proxy server 30. Play a role. The optional contents Data_Select1 and Data_Select2 for each zone may correspond to some of the above-described embedded objects.

In detail, the web server 70 stores content including a common web page that is simultaneously supplied to each zone provided by the content provider and optional content divided by each zone (Data_Select1, Data_Select2), and then for each zone. It is a server that responds when there is a request for content (for example, a web page) from the client A 11, a client B 15, ..., or an information retrieval request for the content.

The content provider of the present invention makes a contract with a plurality of content delivery network (CDN) providers and transmits and stores an object or the like to the proxy server 30 held by each provider. This is to allow the client A 11, the client B 15, and the like to receive a quick response through the proxy server 30 when requesting specific content.

Meanwhile, referring to the configuration of the web server 70, the web server 70 may include a web server DB 71 and an intermediary server 73. The web server DB 71 may include a plurality of digital contents (hereinafter, referred to as “integration”) including a web page to be transmitted to all clients 10 and optional content for each zone (Data_Select1 and Data_Select2) to be transmitted in response to the client 10 for each zone. Service content ').

The mediation module 73 may selectively transmit the corresponding contents among the integrated service contents stored in the web server DB 71 to the proxy server 30 according to a web page request from the proxy server 30.

In addition, the mediation module 73 selectively analyzes the corresponding contents among the integrated service contents stored in the web server DB 71 according to the selective content request signals Sig_Select1 and Sig_Select2 for each zone from the analyzer 40. 40).

4 is a flowchart illustrating a process of collecting selective content in a content refresh method using the user's zone information and selection information according to an embodiment of the present invention, and FIG. 5 is a view showing the zone information and the user's zone information according to an embodiment of the present invention. A flowchart illustrating a process of providing selective content among content refresh methods using selection information. The process of collecting the optional content and the process of providing the optional content may be performed separately.

Before describing each process, the necessary conditions for requesting search information will be described first. When a web page request (URL request) by each zone client (client A (11), client (15), ...), the request is transmitted to the proxy server (30). The proxy server 30 receives the web page from the web server 70 by requesting the web page from the web server 70 of the URL. Thereafter, the proxy server 30 transmits the received web page to each zone client (client A 11, client B 15,...). Through the above process, the process for requesting the search information of FIG. 4 and FIG. 5 by the client of each zone (client A 11, client B 15, ...) may be completed.

First, referring to FIG. 4, the process of collecting the optional content is performed. The client of each zone (client A 11, client B 15, ...) receives the proxy server 30 through a web page. The search information request is made to the analysis unit 40 (S401). Here, the search information request may be performed by inputting terms corresponding to the search information request. Meanwhile, although shown in the drawing as client A 11 and client B 15 as zone-specific clients, there may be additional zone-specific clients. In addition, although the client A 11 and the client B 15 are illustrated as one client, it may be apparent to those skilled in the art that the client A 11 and the client B 15 may be modified to be formed of a plurality of clients.

In step S401, the analysis unit 40 that receives the search information request for each zone refers to the location information DB 35 and requests each client (client A (11), client B (15), ... Identify and classify zones and generate zone information (S402).

The controller 33 transmits the zone information generated in S402 to the analyzer 40 (S403).

The analysis unit 40 collects the number of times for the search information request of the client (s) for each zone classified according to the received zone information for a predetermined time to determine the rank of the search information for each zone, and the threshold value among the number of search information requests. The search information exceeding is extracted for each section (S404).

The analyzer 40 generates an optional content request signal for each zone (first zone selective content request signal Sig_Select1 and second zone selective content request signal Sig_Select2) for the extracted search information, and then selects the optional content request signal. The first zone selective content request signal Sig_Select1 and the second zone selective content request signal Sig_Select2 are transmitted to the web server 70 (S405).

The web server 70 selects the zone-specific content (first zone selective content) matched according to the zone-specific content request signal (first zone selective content request signal Sig_Select1 and second zone selective content request signal Sig_Select2). Data_Select1) and the second zone selective content Data_Select2) are transmitted to the proxy server 30 (S406).

The proxy server 30 may be configured to match the optional content request signal (first zone selective content request signal Sig_Select1 and second zone selective content request signal Sig_Select2) with each zone to the proxy server DB 31. Zone selective content (Data_Select1) and second zone selective content (Data_Select2) are respectively stored for direct transmission according to a request of a zone-specific client (S407).

On the other hand, referring to Figure 5, the process of providing the optional content, the client by each zone (Client A (11), Client B (15)) receives a web page from the Web server 70 by their request After that, the clients of each zone (client A 11 and client B 15) request the search information through the proxy server 30. The request for search information for each zone by the client for each zone is transmitted to the analysis unit 40 of the proxy server 30 described above with reference to FIG. 4, and also to the control unit 33 of the proxy server 40 as shown in FIG. 5. It is transmitted (S501).

The control unit 33 is a zone-specific client (the first zone selective content (Data_Select1), the second zone selective content (Data_Slect2)) stored in advance in the proxy server DB 31 for each zone client (client A (11), client) B (15) determines whether the content that matches the search information request performed in S501 is included (S502).

In an embodiment of the present invention, when the client A 11 requests the search information, the control unit 33 matches the search information request of the client A 11 to the first zone DB 31A of the proxy server DB 31. It is determined whether the zone 1 selective content Data_Select1 is included.

As a result of the determination in S502, the content matching the search information request for each zone performed in S501 for the optional content for each zone (the first zone selective content Data_Select1 and the second zone selective content Data_Select2) in the proxy server DB 31. Is included if: That is, the controller 33 selects the matching content among the optional contents for each zone (the first zone selective content Data_Select1 and the second zone selective content Data_Select2) for each zone (client A 11, client B ( 15)) (S503).

In an embodiment of the present invention, the client A 11 makes a request for search information, and the first zone selective content corresponding to the search information by the client A 11 in the first zone DB of the proxy server DB 31. If Data_Select1 is included, the controller 33 may directly transmit the first zone selective content Data_Select1 to the client A 11.

That is, in this case, since the client (client A 11 or client B 15) is directly received from the proxy server 30 without passing through the web server 70, an efficient digital asset for the web server 70. Management can be performed, and efficient network asset management can be performed from a network perspective.

On the other hand, as a result of the determination in S502, if there is no content matching the respective zones in the proxy server DB 31, the control unit 33 transmits a request for the content corresponding to the search information for each zone to the web server 70. (S504).

In an embodiment of the present invention, the client A 11 makes a request for search information, and the first zone selective content corresponding to the search information by the client A 11 in the first zone DB of the proxy server DB 31. If Data_Select1 is not included, the controller 33 may request the web server 70 for content corresponding to the search information by the client A11.

The web server 70 receiving the request for the content corresponding to the search information in S504, the content corresponding to the search information for each zone through the proxy server 30, the client for each zone (client A (11), client B) (15)) (S505).

In an embodiment of the present invention, the web server 33 passes the content corresponding to the search information request by the client A 11 transmitted by the control unit 33 via the network 50 and the proxy server 30. It can transmit to the client A (11).

FIG. 7 is a block diagram illustrating a configuration of the proxy server X 131 of FIG. 6. It is also. Meanwhile, the gist of the present invention is shown in FIGS. 1 to 5, and hereinafter, FIGS. 6 and 7 illustrate other possible modifications to help understanding of the present invention (FIGS. 1 to 5), and thus will be briefly described or duplicated. Unnecessary explanations are omitted.

6 and 7, the content refresh system 200 includes an X zone client 111, a Y zone client 115, a proxy server X 131, a proxy server Y 135, a network 150, and the like. It may include a web server 170.

Zone X client 111 may include Client 1 (111A), Client 2 (111B), and the like, and Zone Y client 115 may include Client 3 (115A), Client 4 (115B), and the like.

The proxy server X 131 may be connected to the X zone client 111, and the proxy server Y 135 may be connected to the Y zone client 115.

The configuration of each of the clients 111 and 115 and the proxy servers 131 and 135 is the same as that of FIG. 1, and only the proxy server (proxy server X 131 and proxy server Y ( 135), there is a difference that exists separately.

For convenience of explanation, the proxy server X 131 will be described with reference to FIG. 7. The proxy server X 131 may include a proxy server DB 132, a controller 133, and an analyzer 134.

The proxy server X 131 that receives the request for the search information of the zone X (or zone Y) client receives the content from the web server 170 and delivers the corresponding content to the client 110. In detail, the proxy server X 131 may include a proxy server DB 132, a controller 133, and an analyzer 134. The proxy server DB 132 receives and stores the X-zone selective content Data_SelectX that is matched according to the X-zone selective content request signal Sig_SelectX generated by the analyzer 134 and stores it.

In summary, the proxy server DB 132 according to the present invention generates the selective content request signal Sig_SelectX according to its zone, and stores the selective content Data_SelectX according to its zone that matches.

The control unit 133 receives the request for search information for each section from the X zone clients 111A, 111B, ... together with the analysis unit 40, so that the content corresponding to the search information requests of the X zone clients 111 is stored. It is determined whether it is included in the X zone selective content (Date_SelectX) previously stored in the proxy server DB 132.

As a result of the determination, when the content corresponding to the search information requested by the X-zone client 111 matches the X-zone selective content Data_SelectX, the controller 133 directly passes through the X-zone client (not through the web server 170). The X zone selective content Data_SelectX corresponding to the search information request may be transmitted to the client 1 111A, the client 2 111B, ...).

The analysis unit 134 receives the search information request from the X-zone clients (client 1 (111A), client 2 (111B), ...) in real time to generate a comprehensive analysis table, and count the number of search information requests, Search information whose counted count is greater than or equal to a threshold may be extracted for each zone.

The analyzing unit 134 may generate an X-zone selective request signal Sig_SelectX using the extracted search information and transmit the generated X-region selective request signal Sig_SelectX to the web server 170. Accordingly, the web server 170 may transmit the X zone selective content Data_SelectX among the integrated service contents stored in advance to the proxy server X 131, more specifically, the proxy server DB 132.

On the other hand, looking at the analysis unit 134 in more detail, the analysis unit 134 may include an analysis unit DB (134A), analysis module 134B and the content management module 134C.

The analysis unit DB 134 receives and stores a search information request, more specifically, a term corresponding to a search information request from the X zone client 110. In addition, the analysis unit DB 134A may store a comprehensive analysis table generated by the analysis module 134B which will be described later.
