As shown, the service server 100 may include an interface unit 110, a call request confirmation unit 120, a content provider 130, a content determination unit 140, and a database unit 150, Depending on the specific implementation, some configurations may be omitted here. The service server 100 performs overall information processing and data storage for providing a call waiting service according to the present invention and may provide a conventional ring back tone service.

Meanwhile, a series of processes for storing the schedule information and selecting the content data may be performed by the service server 100 or the receiving terminal 300. Hereinafter, an exemplary embodiment in which the process is performed in the service server 100 Will be mainly described.

The interface unit 110 is connected to a mobile communication network or a wired communication network, and transmits / receives data to / from the calling terminal 200 and the called terminal. Hereinafter, each data transmitted / received from / to the originating terminal 200 or the terminating terminal 300 from each configuration of the service server 100 may be transmitted to the originating terminal 200 or the terminating terminal 300 through the interface unit 110, Lt; RTI ID = 0.0 > 300 < / RTI >

The database unit 150 includes a schedule DB 152 and a content DB 154. The schedule DB 152 receives schedule information from the terminating terminal 300 and stores the schedule information. A user of the terminating terminal 300 can input schedule information through an outlook, a calendar site management menu of the portal site or a schedule related application installed on the terminating terminal 300, and the input of the schedule information is generally input as text , Voice input, and the like. The schedule information includes time information including the date and time of the schedule and contents of the schedule, such as '2:00 PM to 4:00 PM, Jan. 16, 2014, department meeting', etc., and the content corresponding to each schedule The selection information of the content to be transmitted to the calling terminal 200 at the time corresponding to the specific schedule.

The content DB 154 stores a plurality of content data. Here, the content data may include various audio or video data as multimedia data that can be provided to the calling terminal 200 by replacing the RBT data in the call waiting time.

The call request confirmation unit 120 confirms a call connection request transmitted from the originating terminal 200 to the terminating terminal 300. More specifically, when the originating terminal 200 requests a call connection, it transmits an incoming ring signal to the terminating terminal 300 from the originating exchange located in the mobile communication network via the destination switching center, and at the same time, It can notify that the call connection request is being made to provide additional services.

The content providing unit 130 provides the content related to the call waiting service to the terminating terminal 300 during the call waiting time. If the schedule information corresponding to the time at which the call connection request is confirmed does not exist, the content providing unit 130 provides the ring back tone signal or the RBT data preset by the terminating terminal 300 to the calling terminal 200 .

Alternatively, if the schedule information corresponding to the time at which the call connection request is confirmed exists, the content data selected by the content determining unit 140, which will be described later, is provided to the calling terminal 200, And outputs the content data during the waiting time.

The content determination unit 140 determines whether schedule information corresponding to a time at which a call connection request is confirmed exists in the schedule DB 152. [ As described above, the schedule information inputted by the user of the receiver terminal 300 includes time information and schedule contents, and it can be confirmed whether the call connection request time is located within the set time in the schedule information.

When there is schedule information within the time, the content determination unit 140 can select the content data corresponding to the schedule information among the plurality of content data stored in the database unit 150. [ Here, various embodiments may exist for the logic for selecting content data.

First, when the schedule information is input as text, the text may be provided to the calling terminal 200, or a machine sound corresponding to the text may be generated and provided to the calling terminal 200.

In addition, a user's voice message or content data may be received and stored in advance from the terminating terminal 300, and the received voice message or content data may be transmitted to the calling terminal 200. For example, it is possible that a user transmits a certain voice message or content data for each schedule having a same content such as a schedule of a specific time, a meeting, a business trip, etc., and outputs the same to the schedule. At this time, the content DB 154 of the database unit 150 stores the voice message or the content data received from the terminating terminal 300, and the schedule DB 152 stores each schedule information as time information, The storage path of the voice message or the content data received and stored together with the receiving terminal 300 can be matched and managed. Accordingly, it is possible to provide the calling terminal 200 with a voice message or content data of the user received from the terminating terminal 300 in the call waiting time.

In addition, the schedule DB 152 of the database unit 150 may receive selection information of contents from a user, and may store and match the schedule information. The selection information of the contents means information for identifying contents to be transmitted to the calling terminal 200 when corresponding to each schedule information. For example, the user of the terminating terminal 300 inputs the name or the ID of the content data together with the schedule information, and inputs the storage path of the content data corresponding to the inputted name or ID into the schedule DB 152, And can be stored. At this time, the content determining unit 140 may extract the content data matched to the corresponding schedule information from the content DB 154 of the database unit 150 and provide the extracted content data to the calling terminal 200.

In the embodiments described above, the content data corresponding to the schedule information is transmitted to the calling terminal 200 according to the intention of the user of the terminating terminal 300. Hereinafter, the content determining unit 140 determines whether or not the calling terminal 200 will be described with reference to FIG.

The content determining unit 140 can generate semantic information from the schedule contents of the schedule information. This is for selecting the content data suitable for conveying that the schedule is determined to the user of the calling terminal 200 and searching for the content data which can recognize the corresponding meaning by grouping according to the meaning of the schedule.

The schedule information inputted by the user can be composed of various types of sentences. It is also possible to set keywords frequently input in schedule information such as meetings, trips and trips, and use at least one of various known syntax parsing techniques The keyword included in the schedule information can be extracted to generate semantic information. At this time, when the user of the receiving terminal 300 inputs the schedule information by voice input, the service server 300 converts the voice input of the user into text information through a predetermined voice recognition engine (not shown) Semantic information can be generated from information.

In selecting the content data corresponding to the generated semantic information, the content deciding unit 140 refers to the schedule information and the content selection information input from the plurality of user terminals, and selects the content corresponding to the schedule information of the terminating terminal 300 Data can be determined.

Meanwhile, the service server 100 may receive schedule information from various user terminals subscribed to the supplementary service, and the schedule information may include each schedule and corresponding content selection information. At this time, the semantic information extracted from the keyword of the schedule information and the selection information of the content data selected by each user can be accumulated and stored in the database unit 150, and the content selected by each user according to the semantic information extracted from the schedule information Can be stored and matched. For example, a list of contents selected by a plurality of users may be generated and ranked according to semantic information such as meetings, trips, and trips. Further, it is possible to match and store selection information of a plurality of users according to semantic information, considering additional information such as sex, age, etc. of the user.

The content determining unit 140 can determine the content data by referring to the selection of various users stored in advance for the semantic information extracted from the schedule information. For example, when the semantic information of the schedule at a specific time is related to the travel, the user selects the content data most selected in the travel schedule by referring to the accumulated data of other users stored in the database unit 150, And can select the content data by further considering the personal information such as the sex and the age of the user of the terminating terminal 300.

The content determining unit 140 can determine the content data corresponding to the schedule information by referring to the history of the schedule information set by the terminating terminal 300. [ For example, referring to the schedule information set by the user of the terminating terminal 300 previously, it is possible to provide the calling terminal 200 with the content data most selected at the time of matching with the semantic information of the corresponding schedule information.

In addition, the content determining unit 140 can search various contents data that can be matched with the schedule information through the Internet using the keyword extracted from the schedule information, and provide the selected contents data to the selected calling terminal 200.

Meanwhile, the process of selecting the content corresponding to the schedule information by the content determining unit 140 may be performed after the user of the terminating terminal 300 inputs the schedule information, or when the call connection is performed by the originating terminal 200 And may be performed when requested.

Unlike the above-described embodiments, the process of selecting contents corresponding to the schedule information may be performed by the terminating terminal 300 rather than the content deciding unit 140 provided in the service server 100. [ That is, when the terminating terminal 300 receives the incoming ring signal through the mobile communication network, it can determine the content data to be transmitted to the originating terminal 200 based on the previously stored schedule information and transmit it to the service server 100.

According to the service server 100 according to the embodiment of the present invention described above, the content data corresponding to the schedule information input by the user of the terminating terminal 300 is selected, and when the originating terminal 200 requests the call, It is possible to transmit the contents data to the caller terminal 200 and provide contents related to the schedule of the caller terminal 300 to the user of the calling terminal 200 at the call waiting time, The call waiting unit can provide the service.

At the same time, the control unit 340 checks whether schedule information corresponding to the time when the incoming ring signal is received exists in the memory unit 330. [ As described above, the schedule information input by the user of the terminating terminal 300 includes time information and contents of the schedule, and it is confirmed whether the time when the call connection is requested from the calling terminal 200 is located within the time set in the schedule information .

The control unit 340 extracts keywords from the schedule information and generates semantic information. The semantic information can be composed of various types of sentences. The keywords can be frequently input to schedule information such as meetings, trips, trips, etc., and at least one of various known syntax parsing techniques The keyword included in the schedule information can be extracted to generate the semantic information. At this time, when the user of the receiving terminal 300 inputs the schedule information by voice input, the voice input engine (not shown) converts the voice input of the user into text information and generates semantic information from the text information have.

The control unit 340 selects the content data corresponding to the created semantic information and requests the service server 100 to transmit the selected content data to the originating terminal 200. [ The service server 100 can store various contents data and when the control unit 340 transmits the identification information such as the name, ID or storage path of the contents data to the service server 100, And can transmit the corresponding content data to the originating terminal 200.

At this time, the content data itself is not necessarily stored in the receiving terminal 300, and it is sufficient that only the information that can identify the content data stored in the service server 100 is transmitted to the service server 100.

To this end, the memory unit 330 matches the identification information of the content with the semantic information, and the controller 340 selects the identification information of the content data matching the generated semantic information and transmits the selected identification information to the service server 100 have. For example, the user of the terminating terminal 300 matches and stores the identification information of the content data corresponding to the semantic information with respect to a schedule having semantic information such as conference, business trip, etc., and the control unit 340 stores the meaning Once the information is known, identification information of the stored content data can be transmitted to the service server 100.

In another embodiment, the user may previously match and store the identification information of the content data corresponding to each schedule information in advance, and the controller 340 may transmit the identification information of the stored content data to the service server 100.

The originating terminal 200 receiving the content data can output the received content data during the call waiting time. The source terminal 200 may include a display unit 350 or an audio output unit 360. The display unit 350 may include an audio output unit 360, It is possible to output the received content data. In addition, during the call waiting time, the terminating terminal 300 notifies the user of the call connection request according to the incoming ring signal, and simultaneously transmits the schedule information corresponding to the current time and the content Information about the data can be displayed together.

The process of selecting the content corresponding to the schedule information by the control unit 340 may be performed by the content determination unit 140 provided in the service server 100, 3 as described above. In this case, the terminating terminal 200 may receive the schedule information from the user and transmit the schedule information to the service server 100.

5 is a flowchart illustrating a service method of a call waiting unit using a service server according to the present invention.

The service server 100 receives and stores schedule information from the terminating terminal 300 (S110). The schedule information includes time information including the date and time of the schedule and contents of the schedule, and the selection information of the contents corresponding to the respective schedules, that is, the contents corresponding to the specific schedule at the time corresponding to the specific schedule, And selection information of contents to be transmitted. The schedule information may also be stored in the terminating terminal 300.

The service server 100 confirms a call connection request transmitted from the originating terminal 200 to the terminating terminal 300 (S120). More specifically, when the originating terminal 200 requests a call connection, it transmits an incoming ring signal to the terminating terminal 300 from the originating exchange located in the mobile communication network via the destination switching center, and at the same time, It can notify that the call connection request is being made to provide additional services.

When the call connection request is confirmed, the service server 100 determines whether there is schedule information corresponding to the time at which the call connection request is confirmed (S130).

If the schedule information does not exist at the corresponding time, the ring back tone signal or the RBT data preset by the user of the terminating terminal 300 is provided to the calling terminal 200 (S160).

If the schedule information is present at the time when the call connection request is confirmed, the service server 100 selects the content data corresponding to the schedule information among the plurality of content data stored in the database at step S140.

Here, various embodiments may exist for the logic for selecting content data.

First, when the schedule information is input as text, the user can generate and provide the machine sound of the text to the calling terminal 200.

In addition, a user's voice message or content data may be received and stored in advance from the terminating terminal 300, and the received voice message or content data may be transmitted to the calling terminal 200.

In addition, in the step of receiving the schedule information, the scheduling information is input and stored together with the schedule information from the user, and the content data corresponding to the content selection information is provided to the calling terminal 200. The selection information of the contents means information for identifying contents to be transmitted to the calling terminal 200 when corresponding to each schedule information. For example, the user of the terminating terminal 300 inputs the name or ID of the content data together with the schedule information, and the service server 100 stores the storage path of the content data corresponding to the inputted name or ID as the schedule information And can be stored.

Also, unlike the above-described embodiments, the service server 100 can select content data to be provided to the calling terminal 200 according to a certain logic.

The service server 100 generates semantic information from the schedule contents of the schedule information. This is for selecting the content data suitable for conveying that the schedule is determined to the user of the calling terminal 200 and searching for the content data which can recognize the corresponding meaning by grouping according to the meaning of the schedule.

The schedule information inputted by the user can be composed of various types of sentences. It is also possible to set keywords frequently input in schedule information such as meetings, trips and trips, and use at least one of various known syntax parsing techniques The keyword included in the schedule information can be extracted to generate semantic information.

In selecting the content data corresponding to the generated semantic information, the service server 100 refers to the schedule information and the content selection information received from the plurality of user terminals and transmits the content data corresponding to the schedule information of the terminating terminal 300 Can be determined.

Meanwhile, the service server 100 may receive schedule information from various user terminals subscribed to the supplementary service, and the schedule information may include each schedule and corresponding content selection information. At this time, the semantic information extracted from the keyword of the schedule information and the selection information of the content data selected by each user can be accumulated and stored in the database unit 150, and the content selected by each user according to the semantic information extracted from the schedule information Can be stored and matched.

The service server 100 can determine the content data by referring to the selection of various users stored in advance for the semantic information extracted from the schedule information.

The service server 100 can also determine the content data corresponding to the schedule information by referring to the history of the schedule information set by the terminating terminal 300. [ For example, referring to the schedule information set by the user of the terminating terminal 300 previously, it is possible to provide the calling terminal 200 with the content data most selected at the time of matching with the semantic information of the corresponding schedule information.

In addition, the service server 100 can search various contents data that can be matched with the schedule information through the Internet using the keyword extracted from the schedule information, and provide the selected contents data to the selected calling terminal 200.

The originating terminal 200 receiving the content data from the service server 100 outputs the received content data during the call waiting time (S170).

Thereafter, when a call with the terminating terminal 300 is connected, the output of the content data is terminated and voice or video communication is performed (S180).

Meanwhile, the service method of the call waiting unit according to an embodiment of the present invention may be implemented in the form of a program command that can be executed through various computer means and recorded in a computer readable medium. The computer-readable medium may include program instructions, data files, data structures, and the like, alone or in combination. The program instructions recorded on the medium may be those specially designed and constructed for the present invention or may be available to those skilled in the art of computer software. Examples of computer-readable media include magnetic media such as hard disks, floppy disks, and magnetic tape; optical media such as CD-ROMs and DVDs; magnetic media such as floppy disks; Magneto-optical media, and hardware devices specifically configured to store and execute program instructions such as ROM, RAM, flash memory, and the like. Examples of program instructions include machine language code such as those produced by a compiler, as well as high-level language code that can be executed by a computer using an interpreter or the like. The hardware devices described above may be configured to operate as one or more software modules to perform the operations of the present invention, and vice versa.

According to the service method of the call waiting unit using the service server according to an embodiment of the present invention, content data corresponding to the schedule information input by the user of the called terminal is selected, It is possible to provide a call waiting service which can transmit the content data and provide the calling terminal user with the content related to the schedule of the called terminal user at the call waiting time so as to recognize the information about the calling party during the call waiting time.
