The characteristic information collecting unit 215 uses the subscriber information included in the multimedia recommendation request received through the transmitting and receiving unit 210 to transmit personal information and status information corresponding to the subscriber information through the transmitting and receiving unit 210. Each of the personal information and the state information received from the personal information management device 130 and the presence management device 135 is temporarily stored in the storage unit 225.

The search code determiner 220 determines a search code corresponding to the content to be searched by the content management server 155 using the content recommendation basic information, personal information, and status information stored in the storage 225. The search code determination method by the search code determination unit 220 will be described in detail with reference to the accompanying drawings.

The storage unit 225 is a means for storing an operation program, content recommendation basic information, preference, personal information and status information corresponding to a subscriber who wants a multimedia recommendation, and the like of the search code determination device 125. It is apparent that the storage unit 225 may be configured of a plurality of memories or a plurality of independent storage areas according to the type of information to be stored.

The feedback processor 230 stores the information by using the corresponding information when any content is selected (downloaded) from the content search list transmitted to the mobile communication terminal 100 in response to the search code searched by the search code determiner 220. The preference corresponding to the content recommendation basic information stored in the unit 225 is updated. As described above, each content item included in the content search list includes a content direct access code that can be automatically connected to the corresponding content when the subscriber selects any content item, and any content item is actually selected. In this case, the case information is stored in the storage unit 225.

The controller 235 transmits and receives a transceiver 210, a characteristic information collector 215, a search code determiner 220, a storage 225, and a feedback unit so that the search code determiner 125 may perform the above-described operations. The processing unit 230 is controlled.

FIG. 6 illustrates an input data structure generated by combining subscriber personal information and status information according to an exemplary embodiment of the present invention, and FIG. 7 illustrates each input data structure according to an exemplary embodiment of the present invention. FIG. 8 is a diagram illustrating a preference for each category corresponding to a field value, and FIG. 8 is a diagram illustrating a classification name extracted corresponding to each field value and a preference of a category-specific input data structure according to an exemplary embodiment of the present invention.

Referring to FIG. 3, in step 310, the mobile communication terminal 100 and the mobile communication network 110 perform a PDP context activation procedure (Packet Data Protocol Context Activation Procedure). That is, when a PDP context activation request for data path setting is received from the mobile communication terminal 100, a Serving GPRS Support Node (SGSN) in the mobile communication network 110 authenticates the authentication procedure of the mobile communication terminal 100. After the IP address is assigned from the Gateway GPRS Support Node (GGSN), the IP address is assigned to the mobile communication terminal 100 and the TCP / IP connection is established.

In operation 315, the mobile communication terminal 100 transmits a multimedia recommendation request through a SIP INVITE message to the SIP server 115. At this time, the SIP server 115 performs a proxy server function to interpret the SIP URI address and perform a DNS query to deliver a SIP invite message to a corresponding destination address. In addition, the SIP server 115 transmits a SIP acknowledgment (PRACK) message to the mobile communication terminal 100 to inform the call processing in progress.

In step 320, the SIP server 115 transmits the SIP invite message to the search code determining apparatus 125 corresponding to the destination address of the SIP URI. In this case, the SIP invite message transmitted to the search code determining apparatus 125 includes an request SDP context, and the request SDP context includes subscriber information and service request information, which are substantial contents for the service request. The search code determination apparatus 125 receives the SIP invite message from the SIP server 115 and initiates a procedure for determining the search code (i.e., steps 325 to 350) to the SIP server 115 at the same time. Sends an acknowledgment (PRACK) message to inform the call processing in progress.

In step 325, the search code determining device 125 uses the user interaction attribute of the OSA (Open Service Architecture) API message to the personal information management device 130 to collect the personal information of the subscriber as a determination element for determining the search code. Send Request Information (API).

The personal information management device 130 corresponds to the request for providing personal information received from the search code determination device 125 in step 330 (eg, service registration information, age, gender, birthday, The marital status, hobby) is extracted, and the process proceeds to step 335 and transmitted to the search code determining apparatus 125 using a Response Personal Info (API) message.

In addition, the search code determination apparatus 125 may determine the search code determination apparatus 125 in order to collect status information corresponding to the subscriber as a determination element for determining the search code in step 340. The presence information request (Request Presence Info (API)) using the message is transmitted to the presence management device (135). Presence management device 135 is the state information (for example, the current location location information (for example, metropolitan area, local cities, resorts, foreign countries, etc.), subscriber current location weather corresponding to the location information of the subscriber, etc. in step 345) Information (e.g., season, temperature, weather, etc.), service request time information (e.g., day of the week, morning, afternoon, midnight, etc.), and the status information collected in step 350 is search code determination device Send to 125. A detailed method of collecting the status information by the presence management apparatus 135 will be described with reference to the accompanying drawings.

In FIG. 3, the search code determination device 125 collects personal information from the personal information management device 130 and then collects state information from the presence management device 135, but according to the actual implementation method, step 325. And step 340 may occur simultaneously or in reversed order. In addition, it is apparent that the temporal flowcharts of steps 330 and 335 and steps 345 and 350 may be implemented differently from FIG. 5.

In operation 355, the search code determination apparatus 125 determines a search code for content search using the personal information and the status information collected through the operations 325 to 350. Hereinafter, a method of determining a search code will be briefly described with reference to FIGS. 4 to 8.

As illustrated in FIGS. 4 and 5, the retrieval code determination device 125 may include subscriber's personal information (eg, age, gender, marital status, etc.) from the personal information management device 130 and the presence management device 135. Collect and store hobbies and status information. 4 and 5 are examples for showing personal information and status information in detail, and in reality, only personal information and status information corresponding to the subscriber may be collected.

The search code determining apparatus 125 formulates the personal information and the status information collected corresponding to the subscriber into an input data structure (see FIG. 6).

The search code determining apparatus 125 stores and manages the classification name and category preference for each category corresponding to the field value of each field included in the input data structure as the content recommendation basic information in the storage unit 225. The initial values of the preference for each classification name may be all equal to 1, and are updated by the operation of the feedback processor 230. In FIG. 7, a classification name for each category and a preference for each classification name corresponding to field values of each field are illustrated. Although only one classification name for each category corresponding to each field value is illustrated in FIG. 7, in practice, a plurality of category classification names and classification name preferences corresponding to each field value may exist. In addition, the content categories that can be applied in the present invention is not limited to a certain quantity, and the number of classification names for each category (for example, dance, ballad, jazz, contemporary, movie music, etc., for each music category) is not limited. As described above.

The search code determining apparatus 125 extracts the classification name having the highest preference among the classification names for each category corresponding to the field values of each field included in the input data structure, and generates individual search code combinations as illustrated in FIG. 8.

Subsequently, the preferences of the classification names of the categories included in the individual search code combinations are summed by the classification names to extract the classification name of the category having the highest preference or the classification name of the most exposed category. In FIG. 8, in the case of the music category, a dance preference sum (ie, 3 + 1 + 3 = 7) is the highest, so the classification name of music contents to be recommended to the subscriber may be dance. Alternatively, since the number of exposures of the dance and ballad is the most (three times), one of the dance or ballad may be the classification name of the music contents. When the sum of the preferences or the number of exposures for the plurality of classification names are the same, the search code determining apparatus 125 may arbitrarily select any category classification name or utilize a random number table. By performing the above-described process for each category, it is possible to determine the classification name for each category for searching for content in each category.

The method described so far has been a method of determining a search code corresponding to all content categories for providing content by presetting the content recommendation service system or the content management server 155 according to the present invention. However, even among subscribers of the same age and gender, the desired category of content may be different, and the quantity of content requesting a recommendation may be different. Therefore, if the user presets a content category and / or a quantity of content to be recommended when using the content recommendation service, and the corresponding information is included in the personal information received from the personal information management device 130, the search code determination device 125 corresponds to the corresponding information. It is possible to recommend content specific to subscribers. In this case, the method of setting the content category and / or the quantity of the content in advance will be apparent to those skilled in the art, and thus description thereof will be omitted. Similarly, as a method for recommending optimal content to each subscriber, a step of allowing a subscriber to input content categories and / or search quantity for each category may be added in a process of transmitting a multimedia recommendation request. In this case, the search code determining apparatus 125 may use the designated information included in the multimedia recommendation request (that is, content categories and / or search quantity for each category) to recommend an optimal content specific to the subscriber.

The search code determining apparatus 125 receives the content search list corresponding to the search code determined in step 360 and then transfers the content search list received in step 365 to the mobile communication terminal 100 via the SIP server 115. send. Step 360 and step 365 will be described in detail.

The search code determining apparatus 125 transmits the determined search code to the multimedia management apparatus 150 through a Request Contents List Info based on MC-Code (API) message to request a content information list corresponding to the individual search code. Obviously, the search code determination device 125 and the multimedia management device 150 may be implemented as a single device, and the search code determination device 125 and the multimedia management device 150 may be implemented as a single device. The code determining apparatus 125 may transmit the individual search code determined for each content category to the corresponding content management server 155.

The multimedia management apparatus 150 receives a list of content information including a search code from the search code determination device 125, divides the search code into a plurality of individual search codes, and then, via a Request Contests List Info (API) message. The content list request including the individual search code is sent to the corresponding content management server 155.

Each content management server 155 that receives the content list request extracts a predetermined amount of content data (for example, five) at random under a category classification name corresponding to the received individual search code, thereby retrieving the individual content search list. It generates and transmits to the multimedia management device 150 through a Response Contests List Info (API) message. In this case, the individual content search list transmitted to the multimedia management apparatus 150 may include the name and content direct access code of each searched content.

Thereafter, the multimedia management apparatus 150 generates one content search list by using the individual content search list received from each content management server 155 and transmits the generated content search list to the search code determination apparatus 125. .

The search code determining apparatus 125 transmits the content search list received from the multimedia management apparatus 150 to the SIP server 115 in addition to the response SDP context in the SIP200 OK message, and sends the SIP server 115 to the SIP server 115. Transmits the received response SDP context to the mobile communication terminal 100. Thereafter, the mobile communication terminal 100 displays the received content search list on the display to enable the subscriber to access arbitrary content. Various methods of displaying the content search list on the display unit may be implemented, and various methods of selecting and accessing an arbitrary content item from the displayed content list may be variously implemented. This may be easily performed by those skilled in the art even if there is no separate description, and thus description thereof will be omitted.

When the subscriber selects and accesses an arbitrary content item included in the content list, the search code determining apparatus 125 determines the preference of the corresponding category classification name stored in the storage unit 225 by Lazy Learning Technique. Increasing increases the accuracy of inference by learning.

9 is a flowchart illustrating a process of confirming a location of a subscriber according to an exemplary embodiment of the present invention.

Referring to FIG. 9, the presence management device 135 receiving the presence information request from the search code determination device 125 sends the subscriber's current location information (ie, a location service (LCS)) to the GMLC 140 that is previously designated in step 910. Information) Send the request.

The GMLC 140 requests the Mobile Application Part (MAP) point code of the SGSN 904 currently registered by the subscriber to the Home Location Register (HLR) 902 in step 915.
