Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram schematically illustrating a system for providing a content push service according to an embodiment of the present invention, and FIG. 2 is a diagram illustrating content push scheduling according to an embodiment of the present invention.

As illustrated in FIG. 1, a system for providing a content push system includes a content push device 110, a gateway 120, and a plurality of user terminals 130.

The content push device 110 receives content from a plurality of content registration terminals (not shown), respectively. The content push device 110 collects and stores usage status information about each content. Here, the usage status information is user's usage information for each content, and various information (for example, usage start time using content, usage end time, subscriber information using content, etc.) to indicate the usage status. It may include.

As such, since the content push device 110 collects and stores usage status information about each content, the content push device 110 extracts the usage status information, and extracts the extracted usage status information by content type according to a time zone. That is, the preference for each type may be calculated by analyzing the content category). The content push device 110 may determine and transmit the push target content and the number of pushes based on the preference for each type. Here, the preference by type is a user's preference calculated by content type (that is, by content category). This will be more clearly understood by the following description.

In the present specification, the push target content is selected content from among registered contents based on the type-specific preference. The push target content may be selected for each content type based on the type-specific preference.

The content push device 110 may transmit the determined push target content to the gateway 120. Hereinafter, the content push device 110 will be described in more detail with reference to the accompanying drawings.

The gateway 120 uses the push target content transmitted by the content push device 110 to correspond to the base station or target subscriber corresponding to the target cell corresponding to the transmission mode (or attribute information) of the push target content. Transmission to the terminal 130.

When the gateway 120 transmits the push target content to the base station corresponding to the target cell, the base station may transmit the push target content to the plurality of user terminals 130 within the coverage of the base station.

As illustrated in FIG. 2, the content push device 110 may receive different types of content from each content registration device. Each registered content has a different degree of preference by the user according to its type. Accordingly, the content push device 110 may calculate a preference for each type according to the type of each content, and determine the push target content and the number of pushes based on the content preference. That is, the content push device 110 may determine the push target content and the number of pushes based on the type-specific preference and transmit the content to the gateway 120. The gateway 120 may push the push target content to the base station of the target cell or the user terminal 130 of the target subscriber in the order transmitted by the content push device 110.

The user terminal 130 is a terminal that receives a mobile communication service through a communication network. The user terminal 130 receives and outputs the content pushed by the content push device 110 through a communication network. For example, the user terminal 130 may be a personal communication service (PCS) phone, a PDA phone, a GSM phone, a WCDMA phone, a CDMA-2000 phone, a DMB phone, or the like.

3 is a block diagram illustrating an internal configuration of a service providing server for scheduling a content push according to type-specific preference information according to an embodiment of the present invention, and FIGS. 4 to 6 are content usage status information according to an embodiment of the present invention. 7 is a view illustrating a type-specific preference according to an embodiment of the present invention.

Referring to FIG. 3, the content push device 110 according to an exemplary embodiment of the present invention includes a communication unit 310, a registration unit 320, a collection unit 330, a preference calculation unit 340, a determination unit 350, and a conversion unit. The unit 360 is configured to include a database 370 and a controller 380.

The communication unit 310 performs a function of transmitting and receiving data with the user terminal 130 and / or a content registration device (not shown) through a communication network. In addition, the communication unit 310 performs a function of transmitting the push target content to the gateway 120 under the control of the control unit 380.

For example, the communication unit 310 may transmit the push target content to the gateway 120 or the user terminal 130 under the control of the determination unit 350.

The registration unit 320 receives a content from a content registration device through a communication network and stores the content in the database 370. A description will be made on the assumption that the content registered from the content registration device is the content to be advertised to each user terminal 130 at the push scheduled time. The content registered by the content registration device is registered together with the content attribute information.

That is, the registration unit 320 registers a variety of attribute information (hereinafter, referred to as content attribute information for convenience of understanding and explanation) of the content together with the registration of the content. The content attribute information includes information on the type (ie, category) of the content, region information to which the content is to be transmitted, information about a target user to which the content is to be sent (ie, age and gender), and transmission format type information of the content (eg, For example, the message may be a short message or a broadcast message (multimedia message). In addition, the registered content may be advertisement content for advertisement, or may be well-known content for notifying arbitrary information (for example, disaster information, lost child, etc.).

The collection unit 330 collects content usage status information for each content from the user terminal 130 and stores it in the database 370. Here, the content usage status information may be a use start time, use end time, and subscriber information of each content.

In this specification, in order to facilitate the understanding and explanation, it is assumed that the collection unit 330 collects the content usage status information, and the description will be focused on this, but the collection unit 330 collects the usage status information for each content type at a certain time. You can also save. The usage status information for each content type may be the total number of users or the utilization rate using the content according to the content type at a certain time.

In the present specification, the collecting unit 330 collects content usage status information, and assumes that the usage status information for each content type is generated and output using the content usage status information.

4 and 6 are diagrams illustrating usage status information for each content type. 4 illustrates usage status information corresponding to a corresponding shopping service when the content type is shopping. Referring to FIG. 4, it can be seen that the shopping service is most active at midnight (that is, from 24 to 1 o'clock A.M.).

5 illustrates usage status information corresponding to a corresponding stock service when the content type is a stock. Referring to FIG. 5, in the case of a stock service, the usage of the corresponding content type increases rapidly in response to the stock opening time, and the usage of the corresponding content type decreases rapidly in accordance with the closing time of the stock. It can be seen that.

FIG. 6 is a diagram illustrating usage status information of the music service when the content type is a music service. As shown in FIG. 6, it can be seen that the music service has seasonal characteristics according to the user's use. Since the main audience using music contents is the student group, it is found that the usage status of users between 6 am and 9 am is lower in February than during other vacations.

In the present specification, for convenience of understanding and explanation, it will be described with an emphasis on assuming that the collecting unit 330 collects content usage status information for each time slot and stores it in the database 370.

The preference calculator 340 extracts content usage status information from the database 370, and calculates preference for each type according to the type of content using the extracted content usage status information. In addition, the preference calculator 340 calculates the scheduling index for each type by using the calculated preference for each type.

In more detail, the preference calculator 340 extracts content usage status information from the database 370. The preference calculator 340 calculates each type of preference according to the type of each content through regression analysis of the extracted usage status information for each type of content.

That is, the preference calculator 340 may calculate the preference for each type using, for example, Equation 1 below.

In FIG. 7, preferences according to time types are illustrated. Comparing the usage status information for each content type illustrated in FIGS. 4 to 6 and the preference for each type according to the time zone illustrated in FIG. 7, it can be seen that the usage status information for each content type and the preference for each content type are similar. That is, the preference for each type may be calculated by multiplying the usage status information for each content type by a weighted time.

The determination unit 350 calculates a scheduling index for each type by using preferences and preset constraints for each type according to the type of the content calculated by the preference calculator 340, and uses the calculated scheduling index for each type to calculate the push target content. Can be determined.

Here, the preset constraint may be preset policy information and / or network resource information. That is, the constraint may be fixed information or ratio information in consideration of the capacity of the system or the capacity of the network at the scheduled content push time.

That is, the determiner 350 may determine the push content threshold value according to a preset constraint. Here, the push content threshold is a threshold of content that can be pushed at the push scheduled time according to each content type. The push content threshold may be set to a fixed value for each time zone, or may be set differently based on the preference for each type according to the content type for each time zone.

The determiner 350 may calculate a scheduling index by using the determined push content threshold value and the preference for each type. Here, the scheduling index may be calculated by reflecting the preference of each type according to each content type.

That is, the scheduling index may be the number of pushable contents (or the number of pushes) according to the content type within the push scheduled time. Accordingly, the determination unit 350 may determine the push target content and the number of pushes using the corresponding scheduling index.

For example, the determiner 350 may calculate a scheduling index by using Equation 2 below.

는 푸쉬 컨텐츠 임계치를 나타내고,

는 유형별 선호도를 나타낸다.Where i represents the content type, t represents time,

Represents the push content threshold,

Indicates preference by type.

As such, when the scheduling index is calculated, the determination unit 350 may select the push target content from among the registered contents using the calculated scheduling index.

In addition, the determination unit 350 may select a transmission target differently according to the transmission mode of the push target content. Here, the transmission mode may be a broadcast content service or a non-broadcast content service.

For example, if the transmission mode of the push target content is a broadcast content service, the determination unit 350 sets the target cell as a transmission target. Therefore, in the case of a broadcast type content service, it is possible to control the push target content to be pushed to the plurality of user terminals 130 existing in the cell coverage. On the other hand, if the transmission mode of the push target content is a non-broadcast content service, the determination unit 350 selects the target subscriber as the transmission target.

For example, if the transmission mode is not a broadcast type content service, the determination unit 350 may select the push schedule time, the last content push time, and the response rate of the subscriber.

For example, the response rate of the subscriber may be calculated using the total number of contents sent to the subscriber and the number of responses responded by the subscriber corresponding to the contents sent. Here, the response may correspond to a server connection for at least one of setting, canceling, and obtaining detailed information of the content corresponding to the transmitted content. If there is a response from the subscriber after the content is pushed (transmitted) to a certain subscriber, the controller 380 may calculate a response rate and update it in the database 370. In the present specification, for the convenience of understanding and explanation, it is assumed that the response rate for each subscriber is stored in the database 370. However, the description will be mainly made of the decision unit 350. That is, the determination unit 350 may select a subscriber for the push target content using, for example, Equation 3 below.

는 마지막 컨텐츠 푸쉬 시간을 나타내고,

는 가입자의 응답율을 나타낸다.Here, j represents a subscriber, t represents a scheduled content push time,

Indicates the last content push time,

Represents the response rate of the subscriber.

In addition, if the transmission mode is a broadcast type content service, the determination unit 350 selects a target cell using the push scheduled time, the last content push time, and the response rate of the cell.

For example, the determiner 350 may select a target cell to push the push target content by using Equation 4 below.

는 대상 셀의 마지막 컨텐츠 푸쉬 시간을 나타내고, 는 셀의 응답율을 나타낸다.Here, k denotes a target cell, t denotes a scheduled content push time,

Represents the last content push time of the target cell, Represents the response rate of the cell.

The response rate of a cell may be an average value of response rates of all subscribers present in the cell. The determination unit 350 may distinguish subscribers included in each cell by using subscriber information stored in the database 370. Subsequently, the determination unit 350 may calculate a response rate of the cell by calculating an average value for the response rate of the subscriber included in each cell.

That is, the determination unit 350 may select a target for transmitting the push target content as a transmission target while having a high response rate and the oldest content transmission. As a result, there is an advantage that can increase the interest of the customer.

The conversion unit 360 performs a function of converting the transmission format determined according to the type of the push target content. The conversion unit 360 may convert the push target content into a transmission format suitable for the user terminal 130 corresponding to the transmission target subscriber list determined by the determination unit 350.

The database 370 stores subscriber information and content usage status information collected by the collection unit 330.

The controller 380 is an internal component of the content push device 110 according to an embodiment of the present invention (for example, the communication unit 310, the register 320, the collector 330, the preference calculator 340). , The determining unit 350, the converting unit 360, and the like.

8 and 9 are graphs simulating the results of scheduling the push content using the type-specific preferences according to an embodiment of the present invention.

8 is a graph illustrating the number of content scheduled according to the preference by type when the threshold of the content to be pushed is fixed. Is a graph illustrating the number of scheduled content.

Referring to FIGS. 8 and 9, it can be seen that the stock content is allocated to be pushed most frequently at 9:00 AM. That is, around 9 am, it can be seen that most subscribers prefer to acquire contents related to stocks.

In addition, it can be seen that in the case of game content, the push is frequently scheduled from 15:00 to 23:00, and the traffic information content is frequently scheduled from 23:00 to 4 pm.

That is, it is understood that the push target content and the number of pushes are determined and transmitted by reflecting the preference by type.

The communication unit 1010 performs a function of transmitting and receiving data with other devices of the mobile communication network through a communication network. For example, the communication unit 1010 receives the push content from the content push device 110 or the gateway 120 and outputs it to the content manager 1030.

The input unit 1020 is a means for receiving a control command, a selection command, or the like for controlling the operation of the user terminal 130 from the user. For example, the input unit 1020 may include a plurality of key buttons (for example, a symbol key such as a number / letter key, * or # key, one or more function keys (for example, a menu key, a call key, a confirmation key, Or a key for a wireless Internet connection) or a touch screen.

The content manager 1030 determines whether to output the pushed content according to the preset setting information. That is, the content manager 1030 controls to output the push content through the display unit 1040 when the push content is mapped to preset configuration information. However, if the push content is not mapped to the predetermined setting information, the content manager 1030 may control the push content not to be output through the display 1040.

The display unit 1040 may control data corresponding to a command input by the user through the input unit 1020 under the control of the controller 1060 (for example, an application execution screen executed by the user, through the input unit 1020). Input commands, etc.) and data received through the communication unit 1010 are displayed. That is, the display 1040 may be, for example, a liquid crystal display (LCD) as a means for outputting text and image data as visual data.

The storage unit 1050 stores an algorithm for operating the user terminal 130 and preset setting information.

The controller 1060 stores internal components of the user terminal 130 (for example, the communication unit 1010, the input unit 1020, the content manager 1030, the display unit 1040, and the storage unit according to an embodiment of the present invention). Unit 1050, etc.) are stored.

11 is a flowchart illustrating a method of pushing content by a content pushing device according to an exemplary embodiment of the present invention.

In operation 1120, the content push device 110 calculates a preference for each type according to each content type by using content usage status information.

As described above, the content push device 110 calculates a regression coefficient by regressing the content usage status information. In addition, the content push device 110 may calculate a preference for each type according to each type of content using a regression coefficient. Since this is the same as described above, overlapping description will be omitted.

In operation 1125, the content push device 110 calculates a scheduling index by using the calculated preference for each type. Here, the scheduling index may be the number of pushes that can be pushed corresponding to the corresponding content type at the push scheduled time, as described above. As such, by calculating a scheduling index for each content type, the number of pushable pushes can be set differently for each content type at a push scheduled time. The scheduling index reflects the usage status information for each time type of content type, and as a result, the push count may be set differently according to the type-specific preference. That is, the content type having high user preference at the push scheduled time may be more exposed to the user by increasing the number of pushes than other content types.

Since the method of calculating the scheduling index is the same as described above, duplicate description will be omitted.
