FIG. 3 illustrates a detailed block configuration of the mobile communication terminal of FIG. 2 according to an embodiment of the present invention. Hereinafter, an operation of each block of the mobile communication terminal will be described in detail with reference to FIG. 3.

The RF unit 304 refers to a comprehensive component of a high frequency processor, an intermediate frequency processor, and a baseband processor. The RF unit 304 primarily processes voice and various multimedia data from an external wireless communication network received through an antenna ANT at a wireless communication band frequency. And the intermediate frequency processing for lowering it back to a low frequency band, and processing the signal into a signal of a frequency band that can be processed by the controller 302 again. The audio unit 306, under the control of the control unit 302, modulates the voice signal input through the microphone MIC into a radio signal, demodulates the received radio signal, and transmits the received radio signal to the speaker SPK as a voice signal. The key input unit 308 includes a plurality of numeric keys, and generates corresponding key data when the user presses a predetermined key and outputs the corresponding key data to the controller 302.

The display unit 300 displays various types of information of the mobile communication terminal 200 under the control of the controller 302, and receives and displays key data generated by the key input unit 308 and various information signals of the controller 302. . In addition, according to the present invention, a user interface screen 322 for registering a friend list 324 which is a main call counterpart to perform a multimedia dictionary download and contents management is displayed.

The controller 302 controls the overall operation of the mobile communication terminal 200, and is installed to manage the download and execution of the RBT / message content in the terminal when the multimedia RBT / message service is executed according to an embodiment of the present invention. The friend management module 320 controls the call connection sound / message content of the call counterpart to be stably executed before performing the voice call.

That is, when a terminal user wants to register a friend who is a main call counterpart by driving a friend management module 320 that performs an operation related to a pre-downloading service of multimedia content for a call connection / message service, the controller 302 manages friend. The module 320 is activated to display a user UI screen 322 of a menu related to pre-downloading of multimedia content on the display unit 300. At this time, the friend management module 320 extracts the existing friend list information stored in the memory unit (S30) and displays it on the user UI screen 322 implemented on the display unit 300 (S32).

Accordingly, when the user list registration for the new call counterpart is required on the user UI screen, the user requests a friend list registration of the new call counterpart (S34). Then, the friend management module 320 receives a friend registration request of a new call counterpart of the user and inquires whether there is free space on the memory unit 310 by referring to memory information of the terminal (S36). Then, the friend management module 320 adds new call counterpart information to the friend list 324 when there is free space on the memory unit 310 (S38), and displays the result of the processing on the user UI on the display unit 300. The screen 322 is provided to allow the user to know that the friend list add registration operation is normally performed.

On the other hand, in the terminal described in the embodiment described above, the user may perform friend registration in various other ways besides directly inputting a friend who is a main call counterpart. That is, for example, the user may select an address book DB or an incoming / outgoing call list stored in the terminal to be displayed on the user UI screen 322 so that the user can select a friend.

In addition, the user may select a friend via the web. In this case, the friend selected through the web is transmitted to the friend management server 212 on the communication network, and the friend list 324 is stored in the friend management server 212. Next, the user may access the input page on the communication network and select a friend through the wireless Internet WAP service such as NATE, not through the friend management module 320 of the terminal. It is sent to the friend management server 212 and a friend list 324 is stored in this friend management server 212.

As another method, the friend management server 212 on the communication network connects with the ring tone / message server 214 and 215, the MSC / VLR 206, the HLR, the priority policy server, etc. The friend may be selected by judging the frequency of use, the content, and the priority of each user. In this case, a friend list is first generated and stored in the friend management server 212. Finally, the friend management module 320 may search the call list and the address book of the terminal to automatically calculate the priority and generate the friend list 324 even if the user does not input.

In this case, a method of transmitting the friend list generated by various methods as described above to the friend management server 212 on the mobile communication network may also be variously implemented. That is, whenever the friend list 324 is updated on the terminal memory unit 310, the friend management module 320 of the terminal accesses the friend management server 212 of the mobile communication network to register the updated friend list. In addition, when the friend list is first updated in the friend management server 212 of the communication network, the friend management server 212 notifies the friend list update by sending an invoke SMS to the terminal 200. In addition, the terminal 200 receiving the notification may receive and store the updated friend list of the friend management server 212. In this case, instead of SMS, the terminal 200-the server 212 may use another call information transfer method is interlocked.

In addition, the terminal or the communication network may periodically synchronize the friend list of the terminal 200 and the friend management server 212 at a predetermined time. In this case, the friend management server 212 notifies the other party of the latest updated information and performs the update.

4 is a flowchart illustrating an operation of downloading content in advance in order to prevent time delay of a multimedia call connection sound / message service in a mobile communication system according to an exemplary embodiment of the present invention. Hereinafter, the operation of pre-downloading multimedia call ring tone / message content in the mobile communication system will be described in detail with reference to FIG. 4.

First, the mobile communication terminal 200 of the present invention includes a friend list 324 which is a main call counterpart to execute a multimedia call ring tone / message content pre-download and a content DB 326 which stores multimedia contents of each friend on the friend list. A friend management module 320 is provided on the memory unit 310 and manages registration and contents of a new call counterpart.

In this case, when the user calls the call counterpart on the friend list 324 using the mobile communication terminal 200 as described above, the mobile communication terminal controller 302 activates the friend management module 320 to make the friend. The multimedia call connection sound / message content registered to the call counterpart registered in the list is pre-downloaded.

That is, the friend management module 320 activated by the control unit 302 reads the friend list 324 information from the memory unit 310 during the pre-downloading of the multimedia content (S40) and moves through the wireless data network. The friend management server 212 implemented in the communication system requests the multimedia call ring tone / message content information registered in the phone number of each main call counterpart in the friend list (S42).

Then, the friend management server 212 implemented in the mobile communication system according to the present invention obtains the URL information of the content registered by the call counterpart to the call connection sound / message server (214/215) (S44), the corresponding mobile communication terminal In step S46, the multimedia content URL information for each friend is transmitted.

Accordingly, the friend management module 320 that receives the multimedia content URL information of the main call counterpart in the friend list 324 from the friend management server 212 uses the URL information to connect the call through the base station 202 and the core communication network. Approach the / message server (214/215) and request the multimedia content information for each call party for the ring back tone / message service (S48), and after downloading the content from the ring back tone / message server (214/215) ( S50), by storing it in the content DB 326 on the memory unit 310 (S52), the content dictionary download for the ring back tone / message service is performed.

Meanwhile, in the method of pre-downloading the multimedia call connection sound / message content in the terminal described above, the terminal may be pre-downloaded in various ways.

That is, for example, the terminal 200 may periodically perform a pre-download at a predetermined period or a predetermined time, or the friend management server 212 may call the terminal 200 at a predetermined time to perform the download. In this case, the call of the terminal 200 in the friend management server 212 may use another call information transmission method in which the transmission of the SMS or the terminal-server is connected instead of the SMS.

Next, when the friend list managed by the friend management server 212 is updated, the terminal 200 may be called to perform a pre-download. At this time, even if the friend list generated by the friend management server 212 is not synchronized with the user's mobile communication terminal 200, the effect occurs only by pre-downloading the content of the friend. This can also be applied when creating a friend list in and skipping the above synchronization procedure.

In addition, when the friend list is updated in the terminal 200, a dictionary download may be performed. In this case, even when the friend list is first updated in the friend management server 212, if there is synchronization between the terminal and the server, this may be applied. In addition, the friend management server 212 described in Figure 4 above, the multimedia call to the ring tone / message server (214/215) to look down the URL of the content and again the terminal 200 downloads the content, The friend management server 212 may use a method of directly transmitting the multimedia content itself to the terminal.

Next, the friend management server 212 located in the communication network manages the multimedia content for the RBT / message service registered by the main call counterpart included in the friend list 324 of each mobile communication terminal user, and the friend list 324. If any friend has changed his or her content, the user can use the SMS, etc. to notify the user's terminal 200 of the change, and the terminal 200 downloads the newly registered content to the terminal 200. There is this. This can be implemented in parallel with the various download methods described above, and is useful as a real-time update function in consideration of an environment in which a user-configured content can be freely changed.

At this time, interworking between the friend management server 212 and the call connection sound / message server (214/215) can be implemented in the following three ways. First, the friend management server 212 periodically retrieves the content information of the main call counterpart on the friend list 324 that is being managed from the ring tone / message server (214/215) to recognize the update fact, and secondly How the call connection tone / message server 214/215 receives and manages the friend list 324 to be notified of the update from the friend management server 212, and changes occur in the content registered by each friend on the friend list 324. If only the method of notifying to the friend management server 212, and finally, the ring tone / message server (214/215) is notified to the friend management server 212 when the content of all users change, friend management server 212 ) Can be implemented by filtering and using them.

5A to 5B illustrate an operation control flow for stably implementing a multimedia call connection sound / message service in a mobile communication system according to an embodiment of the present invention without time delay according to content pre-download.

In step S504, the content URL information of the call counterpart is transmitted.

Then, the calling terminal 200 checks the call ring tone content information of the called party 201 side call partner received from the MSC / VLR 206, and then in the content DB 326 stored in the terminal memory unit 310 of the calling terminal 200. Inquiring whether the same multimedia ring back tone content downloaded in advance exists (S506).

At this time, if the same multimedia call ring tone content does not exist, the calling terminal 200 is connected to the call ring tone server 214 through the wireless data network as in the prior art to download the call ring tone content registered in the destination terminal 201 The ring tone service is performed (S508).

However, in contrast, when the same multimedia content exists in the content DB 326 on the memory unit 310, the calling terminal 200 reads the corresponding multimedia call back tone content from the content DB 326 (S510). By executing the corresponding content immediately without accessing 214 (S512), the delay does not occur in the ring back tone service.

Next, referring to Figure 5b illustrating the operation concept of the call connection message service, the calling terminal user registers the multimedia content to be used as a call connection message to the call connection message server on the mobile communication network (S600), the latitude As shown in Fig. 4, when there is a voice call request from the originating terminal 200 designated as the main call counterpart to the called terminal 201 with the multimedia dictionary download completed (S602), the MSC / VLR 206 receives the corresponding call. The call connection message content URL information of the call counterpart is transmitted to the terminal 201 (S604).

Then, the called terminal 201 checks the content information of the call connection message of the calling party 200, the call partner received from the MSC / VLR 206, and then stores the content DB 326 in the terminal memory unit 310 thereof. Inquiry whether the same multimedia call connection message content downloaded in advance is inquired (S606).

At this time, if the same multimedia content does not exist, the destination terminal 201 is connected to the call connection message server 215 through the wireless data network as in the prior art to download the call connection message content registered in the calling terminal and call connection message The service is performed (S608).

On the other hand, when the same multimedia content exists in the content DB 326 on the memory unit 310, the called terminal 201 reads the corresponding multimedia call connection message content from the content DB 326 (S610). By executing the corresponding content immediately without accessing the message server 215 (S612), there is no delay in the call connection message service.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the invention should be determined by the claims rather than by the described embodiments.
