Description

SYSTEM AND METHOD FOR CONTENT DELIVERY {SYSTEM AND METHOD FOR MANAGING OCCUPATION OF CONTENTS}

The present invention relates to a content providing system and method, and more particularly, to a content providing system and method for limiting the number of users who occupy content, and allowing users who do not occupy the content to wait in order.

In general, online content allows as many simultaneous users as possible, as long as the content provider's or network resources allow.

As described in Korean Patent Laid-Open Publication No. 10-2010-0058690, when the same content is requested from a plurality of terminals, the server provides the corresponding content to all the terminals requesting the same content.

However, in such a case, anyone can access the online service or the contents provided online in real time, and such accessibility lowers the rare value of the contents, thereby depressing users' interest in the contents provided online. Becomes

In addition, since content that is always accessible can be accessed or consumed later, users tend to consume it more carefully, rather than quickly, so that content consumption tends to be delayed.

Furthermore, in the case of providing online content, when a human resource or an offline resource on the provider side is required, the quality of service may be deteriorated when content consumption of many users occurs at the same time.

It is therefore an object of the present invention to provide a system and method for providing content that limits the number of users that can simultaneously occupy online content.

It is another object of the present invention to provide a system and method for providing content that limits the amount of time that an online content can be occupied.

Another object of the present invention is to provide a system and method for providing content that can manage users who want to access online content as a standby.

As a technical means for achieving the above-described technical problem, the content providing method according to the first aspect of the present invention, is performed by a content providing server for providing the content requested to the user terminal, from the first user terminal to the main content; Receiving a request for provision; Checking whether the current number of occupants for the main content is greater than or equal to the maximum number of occupants; And if the current occupant number is less than the maximum occupant number, providing the main content to the first user terminal.

Content providing server according to a second aspect of the present invention, the content providing server for providing the content requested by the user terminal, the content management unit for storing and managing a plurality of main content; Upon receiving a request for providing the main content from the first user terminal with respect to the first main content among the plurality of main contents registered in the content management unit, confirming whether the current number of occupants for the first main content is equal to or greater than the maximum number of occupants. Occupant management unit; When the occupant manager confirms that the current occupant number of the first main content is less than the maximum occupant number, the occupant manager may include a content providing unit configured to provide the first main content to the first user terminal.

According to an embodiment of the present invention having the above configuration, by limiting the number of users who can occupy the online content at the same time, it is possible to increase the scarcity of the content and the expectation of the content by lowering the accessibility to the online content .

According to another embodiment of the present invention, by limiting the time to occupy the online content, it is possible to increase the user's concentration on the content and to promote content consumption.

According to another embodiment of the present invention, by managing the users who want to access the online content as a standby, it is possible to implement an offline liner online.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is "connected" to another part, this includes not only "directly connected" but also "electrically connected" with another element in between. . In addition, when a part is said to "include" a certain component, this means that it may further include other components, except to exclude other components unless otherwise stated.

Hereinafter, with reference to the drawings will be described an embodiment of the present invention. 1 is a configuration diagram schematically showing the configuration of a content providing system according to an embodiment of the present invention.

As shown in FIG. 1, in the content providing system according to an exemplary embodiment of the present invention, the user terminal 100 and the content providing server 200 communicate with each other via a network N.

The network N may include a local area network (LAN), a wide area network (WAN), a value added network (VAN), a personal local area network (PAN), and a mobile communication network (PAN). It can be implemented as all kinds of wired and wireless networks such as mobile radio communication network) or satellite communication network.

The user terminal 100 may be implemented as a computer, a portable terminal, or a television that can be connected to a remote server through a network or connectable with other terminals and servers. Here, the computer includes, for example, a laptop, desktop, laptop, etc., which is equipped with a web browser, and the portable terminal is, for example, a wireless communication device that ensures portability and mobility. , Personal Communication System (PCS), Global System for Mobile communications (GSM), Personal Digital Cellular (PDC), Personal Handyphone System (PHS), Personal Digital Assistant (PDA), International Mobile Telecommunication (IMT) -2000, Code CDMA Division Multiple Access (2000), including all kinds of handheld based wireless communication devices such as W-Code Division Multiple Access (W-CDMA), Wireless Broadband Internet (WBRO) terminals, smart phones, etc. can do. In addition, the television may include an Internet Protocol Television (IPTV), an Internet Television (Internet Television), a terrestrial TV, a cable TV, or the like.

The user terminal 100 may be installed with an application program for exchanging data with the content providing server 200, which will be described later, so that the content received from the content providing server 200 by the application can be displayed or executed. . In this case, the application may be a web browser.

Meanwhile, the content providing server 200 exchanges data with a plurality of user terminals 100 through a network. The content providing server 200 functions as a content provider providing at least one main content to the user terminal 100.

Hereinafter, terms used to describe embodiments of the present invention will be summarized first.

In the following, "content" may be any form of data provided through a network. It should be composed of at least one of text, audio, video, and video and can be divided into one unit. The content may be, for example, a video or audio itself, a virtual space that is independently classified online, such as a bulletin board or a community, or a web page. Furthermore, the manner in which the content is provided may be any one of a download method and a streaming method, and the communication method in which the content is provided may be a connection-oriented method or the connection-less method. May be

That is, in the following, the content may be provided through the network N, and may be all data that can be divided into independent units. Furthermore, the content may be content that requires a user's reaction, such as input or selection of users, or may be content that is actively changed by interaction between the content provider and the user.

In addition, content may be divided into 'main content' and 'sub content'.

'Main content' is content that is intended to be accessed by the real user terminal 100, and is 'object' to be described below, and is content that is consumed by an actual user. On the other hand, the 'sub content' is waiting for the main content to occupy the main content if the user terminal 100 requested to access the main content is not allowed to occupy the main content according to the limitation of the number of occupants set for the main content. As the content provided during, the data may include, for example, data associated with the main content or some of data included in the main content.

Meanwhile, in the following description, 'occupancy' refers to a state in which a user terminal 100 requesting main content to a content providing server 200 providing content maintains a connection between the content providing server 200 and the corresponding main content.

At this time, if the content providing server 200 provides the main content to be occupied to any user terminal 100 in a connection-oriented communication method, a connection is established between the content providing server 200 and the user terminal 100 Until the established connection is released from the time, the user terminal 100 is treated as occupying the main content.

In addition, when the content providing server 200 provides the main content to be occupied by the user terminal 100 in a connectionless communication method, the content providing server 200 is set in advance from the user terminal 100 If the continuous response is received at the following time intervals, the corresponding user terminal 100 can be treated as occupying the content.

In addition, in the following description, 'waiting' means that the user terminal 100 requesting the main content to the content providing server 200 that provides the content occupies the same as described above with respect to the content providing server 200 and the sub content associated with the main content. It means a state of continuing. That is, when the sub content is provided in a connection-oriented communication method, the corresponding user terminal 100 from when the connection for providing the sub content is established between the content providing server 200 and the user terminal 100 is released. ) May be treated as waiting for main content.

In addition, when the sub-content is provided in a connectionless communication method, if the content providing server 200 receives a continuous response from the user terminal 100 at a time interval less than a predetermined period, the corresponding user terminal 100 It can be treated as being in a waiting state for the main content. At this time, the period set to determine the standby state may be set longer than the period set to determine the occupancy state for the main content. In addition, since the communication environment is relatively poor when the user terminal 100 requesting the content is the mobile user terminal 100, the connection state may be determined by setting a relatively long period of time for the mobile user terminal 100. .

Furthermore, `` departure '' from the `` occupation '' or `` waiting '' below means that the occupancy or waiting is terminated, and when the main content or the sub content is provided in a connection-oriented communication method, the occupancy or waiting is performed when the connection is released. In the case where the user terminal 100 is treated as detached and the main content or the sub content is provided in the connectionless communication method, the time corresponding to the preset period from the time of the final response from the user terminal 100 is increased. When the next response is not received until the elapsed time, the user terminal 100 can be treated as being released from the occupied or standby state.

In addition, hereinafter 'occupant' refers to the user terminal 100 occupying the main content, and 'waiter' refers to the user terminal 100 connected to the sub content in order to occupy the main content.

Hereinafter, the configuration of the content providing server 200 included in the content providing system according to an embodiment of the present invention will be described based on the terms described above.

2 is a functional block diagram showing the configuration of a content providing server included in a content providing system according to an embodiment of the present invention.

As shown in FIG. 2, the content providing server 200 includes a content management unit 201.

The content management unit 201 may first store one or more main contents, and may associate and store identification information of the main contents and information on the maximum number of occupants allowed for each of the stored main contents. In addition, the content management unit 201 may store the sub content that is dependent on each main content or a plurality of main content, and may record the association relationship by storing the main content and identification information of the sub content in association with each other.

In addition, the content management unit 201, when the main content is provided to the user terminal 100 in a connectionless manner, that is, for example, if the main content is a general web page, for the main content of the user terminal 100 Periodic information needed to check the occupancy can be correlated and stored.

Furthermore, the content management unit 201 may store the time limit information in association with the main content when there is a limit in the time that one user terminal 100 may occupy the main content. However, if the period information or timeout information is the same for all main contents, they may not be stored in association with each other.

Meanwhile, in order to limit the number of occupants, the content providing server 200 continuously updates and stores the occupancy count information, and manages the occupant number for any main content below a preset maximum occupant number. 202).

The occupant management unit 202 continuously monitors the occupancy or departure from the main content, thereby recording the current occupant number for the main content, and accordingly, only the occupants having the predetermined number of occupants below the predetermined maximum occupancy number. To provide content.

Occupant management unit 202, for example, if the maximum number of occupants of any main content is 1, if there is no current occupant state to manage the occupancy count to 0, if the new occupant occupies the main content so that the occupancy count is 1 can do. Accordingly, even if a main content request of another new user terminal 100 is received, the main content may not be provided to the other user terminal 100. In addition, if the occupant leaves possession of the main content, the occupant management unit 202 changes the occupancy count back to 0, and responds to the main content request of the other user terminal 100, where the main content is different from the user terminal 100. ) Can be provided.

That is, the occupant management unit 202 may continuously compare the current occupancy count with the maximum number of occupants set for the corresponding main content, so that the content providing unit 203 to be described later blocks additional access to the main content.

In addition, when the maximum occupant number is set to 1, the occupant manager 202 may set an occupancy flag on the main content to distinguish between an occupied state or an unoccupied state. Accordingly, if the flag is set, additional access to the main content may be blocked, and if the flag is not set, access to the main content may be allowed. However, hereinafter, it will be described by determining whether to provide the main content based on the occupancy count.

Meanwhile, the content providing unit 203 of the content providing server 200 selectively provides the main content to the user terminal 100 by allowing or blocking the access of the user terminal 100 to the main content stored in the content management unit 201. do.

The content providing unit 203 blocks access to the main content of the user terminal 100 by applying separate blocking logic to access to the main content, or provided by the database itself in which the main content is stored. It may be implemented using a locking function.

However, if the occupancy count counted by the occupant manager 202 is less than the preset maximum occupant number, the content provider 203 may provide the main content to the user terminal 100.

In addition, the occupant management unit 202 can record the time the current occupant occupies the main content, so that it can be compared with the preset time limit information.

If the time that one occupant can occupy for any main content is limited in advance, the occupant management unit 202 records the elapsed time from the occupancy start time of each occupant and stores the elapsed time with timeout information. Can be compared.

Accordingly, when the elapsed time is more than the time limit, the occupant management unit 202 notifies the content providing unit 203, the content providing unit 203 may stop providing the main content to the occupant. If the main content is provided to the occupant in a connection-oriented communication method, the content providing unit 203 may stop providing the main content by releasing the connection established between the occupant and the content providing server 200. And if the main content is provided to the occupant in a connectionless communication method, the content providing unit 203 is occupied when the response or request related to the main content is received from the occupant who has stopped providing the main content ( Other content (for example, a webpage, etc.) indicating that the main content has been stopped may be provided.

If the main content for any occupant is stopped in this way, the occupant manager 202 may set the occupancy count to -1 so that the new occupant is provided with the main content.

On the other hand, the occupant management unit 202, the main content (for example, a web page, etc.) provided in the connectionless communication method, to continuously provide content in the user terminal 100 in the main content in order to determine whether or not occupied. Insert a script to generate a response signal to the server 200, or continuously sends a request for a response from the content providing server 200 to the user terminal 100, or the continuous action of the occupant in the main content itself By inserting a user interface (e.g., a persistent refresh request), a periodic response can be generated.

Meanwhile, if the content providing unit 203 receives a main content provision request from the new user terminal 100 with respect to the main content that already has the same occupancy count as the maximum number of occupants, the user terminal 100 that has requested the main content provision is provided. A message indicating that the content is already occupied can be transmitted.

In addition, according to an embodiment, the content providing unit 203 does not provide the main content when the main content providing request is received from the new user terminal 100 for the main content which already has the same occupancy count as the preset maximum occupant number. Without providing the sub-content corresponding to the requested main content.

In this case, the content providing server 200 requests the main content, but the user terminal 100 receiving sub-content other than the main content from the content providing unit 203 because the number of occupants is equal to or greater than the maximum number of occupants. It may include a waiting manager 204 to register and manage the waiting list.

At this time, there may be more than one waiter managed by the waiter manager 204, and the waiter manager 204 may register and manage the waiter list in the order in which the waiters are requested to provide the main content.

Here, the content providing unit 203 may provide sub content to the waiter. As described above, the sub content may be a limited form of the main content, including a part of data included in the main content. For example, it may be one minute preview content for video content. Or, for example, the data contained in the main content may be provided to the waiter while the waiter may limit the actions that the occupant can perform on the main content. That is, while limiting the number of occupants for the main content, the sub-content can be configured so that the waiter can only view a part of the main content or at least partially limit the actions that a user can perform on the main content.

Further, the sub content may be multimedia content to prevent boredom of time, or may include an advertisement so as to obtain an advertisement effect on the waiting person.

At this time, the standby management unit 204 can continuously check whether the connection to the sub-content of the waiters in order to manage the user terminal 100 to maintain the standby state as a user terminal 100 requesting to provide the main content as a standby. have.

For example, when the content providing unit 203 provides the sub content in the connection-oriented communication method, the standby management unit 204 is not disconnected after all the user terminal 100 is connected to the content providing server 200 is established. Can be managed continuously as a waiter. The disconnected user terminal 100 may exclude the waiting, and may provide the remaining waiters with an opportunity to occupy the main content in order.

Also, for example, when the content provider 203 provides the sub-contents to the waiters in a connectionless manner, the wait manager 204 waits only when a response is continuously received from the waiters within a predetermined period. You can choose not to exclude waiters from the list.

In addition, the waiting manager 204 manages a plurality of waiters without a sequence, when the occupancy count is less than the maximum number of occupants, randomly select one of the plurality of waiters as the next occupant, the content provider 203 is a corresponding user The main content may be provided to the terminal 100. Of course, the content providing unit 203 may give the main content occupancy opportunities to the waiting people in turn. Here, the waiting order of the waiters may be continuously changed depending on whether the occupants are taken out of occupancy and whether the waiters are released.

Of course, the standby management unit 203, if the user terminal 100 corresponding to the wait is removed from the sub-content, remove the user terminal 100 from the wait list, and adjusts the waiting sequence of the subordinate waiters, such as sub-content of the waiters You can also keep an eye on the connection to.

On the other hand, the content providing unit 203 may provide information for the occupant and the waiter to check the occupancy state of the main content managed by the occupant manager 202 and the waiting state managed by the wait manager 203.

The content provider 203 may provide the occupant with the main content, at least one of elapsed time or available occupancy time information for the main content, and information on the number of waiting persons. In addition, the content providing unit 203 may provide the waiter with at least one of the wait sequence information of the waiter, the number of waiters, and the estimated wait time together with the sub content, and further, the occupant of the main content corresponding to the sub content. Occupancy remaining time information may be provided.

Accordingly, the occupant can increase the concentration of the contents by checking the waiting time or the remaining time for the main contents occupied by the occupant, and especially when the occupant's decision is required for the content (for example, If the product is a product sales web page, and the product can be purchased only in the occupied state), the occupant can make a decision more quickly in consideration of the time or effort to wait to seize the content again later. In addition, the waiter can determine his or her wait time by checking the wait sequence number.

Referring to FIG. 3, the steps performed by the content providing server 200 for one main content will be sequentially described again.

When the main content providing request is received from any user terminal 100 (S101), the content providing server 200 first checks the maximum occupant number and occupancy count of the corresponding main content (S102), and the current occupancy count is maximum. If the number of occupants is smaller than that, the occupancy count is increased by one (S103), and at the same time, the user terminal 100 requesting to provide the main contents is treated as an occupant and the main contents are provided to the user terminal 100 (S104).

If the occupant of the main content occupying the main content exceeds the preset time limit, or even before the time limit is occupied by the occupant for the main content (S105), the content providing server 200 content for the occupant The provision is stopped (S106), and the occupancy count is decreased by one (S107).

And the content providing server 200, if there is a waiter in the state where the occupant is one, the process of providing the main content to the new occupant and increase the occupancy count by 1 again by changing the first rank waiter of the one or more waiters to occupant (S108) Repeat.

In this case, the content providing server 200 may continuously monitor whether the connection established between the occupant and the occupant is released or detect whether a response within a predetermined period is continuously received from the occupant in order to detect the deviation of the occupant. .

On the other hand, if the occupancy count is the same as the maximum occupant number at the time of receiving the content providing request, the content providing server 200 registers the user terminal 100 requesting the main content as a waiting list in the waiting list, and assigns the waiting sequence number. It may be (S109). At this time, the sub-content may be provided to the waiter so as to wait to occupy the main content.

If the waiter stays in the sub-content and does not leave the waiting state, the waiting order is continuously changed to the previous rank according to the departure of other occupants or senior waiters.

Accordingly, when the waiter becomes the first waiter and the occupant passes the time limit or voluntarily intentions, the content providing server 200 converts the first waiter into a new occupant so that the main content is provided. can do. That is, if any one of the occupants of the main content deviates from the occupancy state, the content providing server 200 selects the first priority waiter among the user terminals 100 registered in the wait list (S110). Thus, the first priority waiter can be a new occupant (S108).

However, the content providing server 200 determines whether the waiter for the particular main content is the first waiter, and if it is not the first waiter, depending on whether the occupant or senior waiter is out of the waiting state (S111), by changing the waiting order number of the waiter. (S112), the standby sequence number gradually changes to the priorities.

According to this, users line up and consume online content. As a result, the user may not be able to read the content or perform a predetermined action on the content until his turn, and the expectation of the content may be increased. Furthermore, the pride of occupying or consuming content that is scarce for users who have already occupied or consumed content can be used, and thus embodiments of the present invention can be utilized as an advanced marketing method for online content.

Furthermore, when human resources or offline resources are required to provide online content, such as online counseling, this time-dependent resource can be efficiently allocated and distributed to users fairly.

In addition, there is an advantage that all services provided on a first-come, first-served basis can be implemented as it is online through an offline queue.

This allows you to sell limited edition products online and make sales pages accessible on a first-come, first-served basis, to queue customers for a specific person's online consultation, or to consume multimedia content at a time. It is possible to utilize the embodiments of the present invention in various marketing methods, such as to induce interest of the remaining users of the content by making it possible.

The method according to the embodiment of the present invention described above may also be implemented in the form of a recording medium containing computer executable instructions, such as a program module executed by a computer. Computer readable media can be any available media that can be accessed by a computer and includes both volatile and nonvolatile media, removable and non-removable media. In addition, computer readable media may include both computer storage media and communication media. Computer storage media includes both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Communication media typically includes computer readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave, or other transmission mechanism, and includes any information delivery media.

The foregoing description of the present invention is intended for illustration, and it will be understood by those skilled in the art that the present invention may be easily modified in other specific forms without changing the technical spirit or essential features of the present invention. will be. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. For example, each component described as a single type may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined form.
