     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. 
     A structure of a terminal and a method for executing a DCD service in the terminal in accordance with the preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. 
     In this description, a DCD service is a service for delivering personalized contents to the terminal. 
       FIG. 1  is a block diagram illustrating a terminal for supporting the DCD service and a system thereof in accordance with a preferred embodiment of the present invention, and  FIG. 6  is an exemplary diagram illustrating DCD service screens executed on the terminal of  FIG. 1 . 
       FIG. 1  will now be explained with  FIG. 6 . 
     Referring to  FIG. 1 , the system includes the terminal  100  for supporting the DCD service, and a DCD server  200 . 
     In detail, the terminal  100  for supporting the DCD service includes a user profile  110 , a first module  120  and a second module  130 . 
     The user profile  110  includes personalization information, in more detail, a condition set by a user or generated by automatically analyzing patterns of using of contents by the user. Preferably, the condition includes at least one of a geographical position variation of the terminal  100 , coming of a designated time and an externally-inputted value. The personalization information set in the user profile  100  can be provided to the DCD server  200  by the request. 
     Preferably, the user profile  110  can be stored in a detachable memory means such as an SIM or UIM. Here, the SIM and the UIM are detachable smart cards including a microprocessor and a memory chip. It is easily understood by the ordinary people in the field to which the present invention pertains, and thus detailed explanations thereof are omitted. 
     The first module  120  receives contents from the DCD server  200 . For example, the contents can be broadcast contents, contents of a specific channel selected by the user, or personalized contents. Here, the broadcast contents can be contents transmitted from the DCD server  200  to many and unspecified terminals, and the contents of the specific channel can be contents preferred by the user, such as music, motion picture, still image, cartoon, e-book, game and news. The personalized contents can be specific contents customized to the terminal  100 &#39;s the user, such as news, weather information, stock information and exchange rate information to be provided to the user in a specific time point, and information provided to the user according to the position of the terminal  100 , such as traffic information, surrounding area information and information relating to a specific region. The first module  120  can directly receive the personalized contents from the DCD server  200 , or indirectly acquire the personalized contents by selecting the personalized contents among the contents to be received from the DCD server  200  by itself. 
     The first module  120  can receive the contents from the DCD server  200  in various ways, for example, a push method for providing the contents from the DCD server  200  to the terminal  100  without the request of the terminal  100 , and a pull method for receiving the contents by the request. The pull method will later be described with explanation of the second module  130 . The push method is easily understood by the ordinary people in the field to which the present invention pertains, and thus detailed explanations thereof are omitted. 
     On the other hand, the second module  130  drives the received contents. Here, the terms of driving the contents means playing back the personalized contents and the broadcast contents, namely, displaying the contents or outputting sound contained in the contents. Preferably, playing back the contents is playing back the title or part of the contents. The title or part of the contents can be played back in a ticker type. Accordingly, the contents can be efficiently visually provided to the user. That is, since the whole contents are not played back, the user can comfortably use another function of the terminal  100 . If an external request, namely, a user request is made on the contents whose title or part has been played back, the second module  130  transmits the request for additional information to the first module  120 , so that the first module  120  can receive the additional information. 
     The second module  130  transmits the contents request to the first module  120  so that the first module  120  can receive the contents from the DCD server  200  by the pull method. Here, the contents request can include a contents ID. 
     The contents request can be made by the following two methods. That is, the contents request is made when the user arbitrarily requests the contents, or the contents request is automatically made by the second module  130  when the condition included in the user profile  110  is satisfied. The latter will now be explained in detail. When the condition included in the user profile  110  is satisfied, the second module  130  generates a DCD event and transmits the contents request to the first module  120 . The first module  120  transmits a contents request to the DCD server  200  and receives the contents. Whether the condition is satisfied can be directly monitored by the second module  130 . Also, the condition can be regarded as being satisfied by an externally-inputted value, namely, a direct command from the user. 
     For example, when the condition is 8:30 a.m., if it is 8:30 a.m., the second module  130  transmits the contents request to the first module  120  in order to drive the services necessary at the time, such as weather information of  FIG. 6   a , news and e-mail. As another example, when the condition is the geographical position variation, if the geographical position of the terminal  100  is confirmed, the second module  130  transmits the contents request to the first module  120  in order to drive the traffic information and the surrounding area information of  FIG. 6   b  or the information relating to the specific region. As yet another example, when the condition is satisfied by a direct command of the user for receiving the exchange rate information of  FIG. 6   c , contents of pre-set specific category (or channel) such as music, music video and show business news, or contents of a specific channel, the second module  130  transmits the contents request to the first module  120  in order to drive the contents. Such examples can be appropriately combined. For instance, if the condition is satisfied by the direct command of the user for receiving the contents existing within the pre-set specific category range or the contents of the specific channel, the second module  130  can transmit the contents request. Thereafter, if the geographical position variation of the terminal  100  is confirmed, the second module  130  can transmit the contents request to drive the traffic information, the surrounding area information or the information relating to the specific region. 
     On the other hand, when the condition is not satisfied or is completed, the second module  130  can drive the broadcast contents from the DCD server  200 . 
     However, when the condition is re-satisfied, the second module  130  can request the first module  120  to stop receiving the broadcast contents, thereby preventing a communication fee from being excessively imposed on the terminal  100 , and the user from being confused by a few contents received and driven at the same time. 
     In addition, if the condition different from the satisfied condition is satisfied, the second module  130  generates an event corresponding to the new condition, and requests interruption of reception of the driven personalized contents. 
     Although not illustrated, the components of the terminal  100  explained above, for example, the first module  120  can be comprised of a processor and an RF transmitting/receiving unit, and the second module  130  can be comprised of a display unit and a sound output unit. It is easily understood by the ordinary people in the field to which the present invention pertains, and thus detailed explanations thereof are omitted. 
     The DCD server  200  provides the broadcast contents, the contents existing within the specific channel range, and the personalized contents to the terminal  100 . Here, the DCD server  200  can acquire the contents through an external contents provision server. 
     As described above, the DCD server  200  can provide the broadcast contents by the push method, and the contents existing within the specific channel range and the personalized contents by the pull method, namely, at the request of the terminal  100 . However, it must be recognized that the DCD server  200  can also provide the contents existing within the specific channel range and the personalized contents by the push method. 
     In the case that the DCD server  200  provides the contents, especially, the personalized contents by the pull method, the DCD server  200  can provide the personalized contents only at the contents request of the terminal  100 . Here, in order to provide the personalized contents, the DCD server  200  can personalize the stored contents. In other word, the DCD server  200  can select the contents customized to the terminal  100 &#39;s a user among the stored contents. The personalized contents can be selected by a contents ID included in the contents request from the terminal  100 , or personalization information that can be received from the terminal  100  by a special request. Also, the personalized contents can be selected by acquiring the personalization information from an external server. 
     In addition, in the case that the DCD server  200  provides the contents, especially, the personalized contents by the push method, the DCD server  200  monitors whether the condition pre-set in the terminal  100  is satisfied, and selects and provides the personalized contents according to the result. 
     On the other hand, when transmitting the personalized contents, the DCD server  200  can stop transmitting the broadcast contents, thereby preventing a communication fee from being excessively imposed on the terminal  100 . 
     If the condition different from the condition satisfied in the terminal  100  is newly satisfied, the DCD server  200  stops transmitting the personalized contents, and transmits personalized contents corresponding to the new condition. 
     The DCD server  200  can transmit only the title or part of the contents. However, the DCD server  200  can transmit detailed information on the contents at the request of the terminal  100 . Here, the DCD server  200  can charge the terminal  100  a fee for the detailed information. The technical contents for the charging process are easily understood by the ordinary people in the field to which the present invention pertains, and thus detailed explanations thereof are omitted. 
     Although not illustrated, as obvious to the ordinary people in the art, the DCD server  200  can be comprised of a processor, a network interface and a storing device. 
     The structures of the terminal  100  for supporting the DCD service and the DCD server  200  in accordance with the preferred embodiment of the present invention have been described. The operations thereof will now be explained in more detail. 
       FIG. 2  is an exemplary flowchart showing the operations between the terminal and the server of  FIG. 1 ,  FIG. 3  is another exemplary flowchart showing the operations between the terminal and the server of  FIG. 1 , and  FIG. 4  is an exemplary diagram illustrating signals generated in the operations between the terminal and the server of  FIGS. 2 and 3 . 
     As illustrated in  FIG. 2 , when the terminal  100  is booted, the terminal  100  drives default contents, is registered in the DCD server  200 , and receives and drives broadcast contents from the DCD server  100 . If the pre-set condition is satisfied, the terminal  100  receives and drives personalized contents. The operations between the terminal  100  and the DCD server  200  will now be explained in detail. 
     (1) First, the terminal  100  for the DCD service is booted. 
     (2) The second module  130  of the terminal  100  drives default contents. Here, the default contents can be summarized information on the receivable contents, or summarized information on the contents previously received by the terminal  100 . 
     (3) The first module  120  makes a log-in request to the DCD server  200 . 
     (4) The DCD server  200  receiving the log-in request confirms whether the terminal  100  has been registered as a member, and accepts the log-in request. The terminal  100  is in a standby state for receiving the DCD service from the DCD server  200 . 
     (5) The first module  120  receives broadcast contents from the DCD server  200 . 
     (6) The first module  120  receives the broadcast contents, and transmits the broadcasts contents to the second module  130 . 
     (7) The second module  130  drives the received broadcast contents. Here, driving the broadcast contents can be displaying or sound-outputting the title or part of the broadcast contents. 
     (8) When the pre-set condition is satisfied, the second module  130  generates a DCD EVENT and transmits a REQUEST message to the first module  120 . 
     Preferably, as shown in  FIG. 4   a , the DCD EVENT can have a moduleID parameter for notifying a source of a signal, and an EventType parameter for defining the generated event. 
     Preferably, as shown in  FIG. 4   b , the DCD SERVICE REQUEST message can have a ContentID parameter for notifying an intrinsic ID of the contents requested by the first module  120 , and a DCDEventType parameter for notifying event type information so that the DCD server  200  can search for the contents requested by the terminal  100 . 
     (9) The first module  120  transmits the REQUEST message to the DCD server  200 . 
     (10) The DCD server  200  in response to receiving of the REQUEST message personalizes contents according to the ContentlD parameter included in the REQUEST message. 
     (11) The DCD server  200  transmits the personalized contents to the first module  120  of the terminal  100 . Here, the contents can be loaded on a GENERATE CONTENT message and transmitted to the terminal  100 . 
     Preferably, as shown in  FIG. 4   c , the GENERATE CONTENT message can have a Boolean type SERVICE Result parameter. When the DCD server  200  has found the contents for the corresponding event, the DCD server  200  adds the contents and the SERVICE Result parameter having a TRUE value to the GENERATE CONTENT message, and transmits the resultant message. In the case that the DCD server  200  has not found the contents for the corresponding event, the DCD server  200  adds the SERVICE Result parameter having a FALSE value to the GENERATE CONTENT message, and transmits the resultant message. 
     (12) The first module  120  receiving the personalized contents from the DCD server  200  transmits the personalized contents to the second module  130 . 
     (13) The second module  130  drives the personalized contents, and generates DCD EVENT FINISHED. As shown in  FIG. 4   d , the DCD EVENT FINISHED can have one of a PROCESS_COMPLETE parameter for notifying successful completion of the operation, and a PROCESS_FAIL parameter for notifying failure of the operation. 
     As discussed earlier, when the condition is satisfied, the second module  130  of the terminal  100  generates the event and transmits the contents request. However, the DCD server  200  can also monitor whether the condition is satisfied, and provide the personalized contents without the request of the terminal  100 . For example, when the condition is the geographical position variation of the terminal  100 , the DCD server  200  monitors the position of the terminal  100  by using a global positioning system, and transmits the personalized contents such as the traffic information and the surrounding area information according to the position variation. It will now be explained with reference to  FIG. 3 . 
     As depicted in  FIG. 3 , the DCD server  200  acquires personalization information of the terminal  100 , and provides personalized contents. 
     (1) The DCD server  200  acquires contents through the external contents provision server. 
     (2)˜(3) The DCD server  200  acquires personalization information of the terminal  100  through an external personalization server or the terminal  100 . 
     (4) The DCD server  200  personalizes the acquired contents according to the personalization information. 
     (5) The DCD server  200  transmits the contents to the first module  120  of the terminal  100 . 
     (6)˜(8) This process is identical to that of  FIG. 2 . 
       FIG. 5  is an exemplary flowchart showing the method for providing the DCD service executed in the terminal of  FIG. 1 . 
     Referring to  FIG. 5 , the terminal receives broadcast contents from the DCD server (S 101 ). The terminal drives the received broadcast contents (S 102 ). 
     When the specific condition is satisfied among the predefined conditions (S 103 ), the terminal receives personalized contents corresponding to the condition (S 104 ). The terminal drives the received personalized contents (S 105 ). The personalized contents have been described above. 
     When the user makes a request for detailed information on the received contents (S 106 ), the terminal requests the detailed information on the contents to the DCD server, and receives the detailed information (S 107 ). The terminal drives the received detailed information (S 108 ). For example, when the personalized contents are traffic information, the detailed information can include a smooth traffic flow section or a traffic congestion section, and when the personalized contents are weather information of the day, the detailed information can include weather information of the week. 
     When another condition is satisfied among the pre-set conditions (S 109 ), the routine goes back to S 104  to repeat the process for receiving personalized contents corresponding to the new condition. Here, when the new condition is satisfied, the terminal does not receive the personalized contents corresponding to the previous condition any more. 
     However, when another condition is not satisfied among the pre-set conditions (S 109 ), the terminal repeats the process for receiving the broadcast contents from the DCD server, completes the whole process, or enters into a standby state. 
     As discussed earlier, in accordance with the present invention, the personalized contents are provided to the user of the terminal, so that the user can easily access the contents. In detail, when the condition pre-set by the user is satisfied, the personalized contents corresponding to the condition are provided at the right time and place. 
     As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalence of such metes and bounds are therefore intended to be embraced by the appended claims.
