Title: System and method for providing multimedia object linked to mobile communication network

Description:
TECHNICAL FIELD 
     The present invention relates to a system and a method for providing a multimedia object linked to the mobile communication network, wherein a user transmits a multimedia expression object he or she has set up to the terminal of a communication party via a data communication network so as to make the object displayed on the terminal at the time of originating a call or receiving a call, in the middle of a call, or at the end of a call and to allow an interaction with the multimedia expression object displayed on the terminal. 
     BACKGROUND ART 
     Generally, a mobile terminal is an apparatus for exchanging information with a communication party by establishing voice communication with the communication party via a mobile communication network. The mobile terminal having such a function is provided with various services. The services are classified into the followings based on information exchange and networks. 
     Firstly, there is a service for information exchange between user parties as the original purpose of the terminal. This service provides an information exchange method besides voice communication or a method for establishing voice communication while performing the exchange of additional information. A representative service of the former is Short Message Service (SMS), a representative service of the latter is a video communication system. Meanwhile, there is a service for a user&#39;s information to a communication party regardless of the user&#39;s intention, an example of which is the caller identification service. 
     Secondly, there is a service which uses the voice or data communication function of the mobile communication network but is personally utilized by a user directly regardless of information exchange between user parties. Examples of this service include a personal ring-back-tone service, a ring service, a service for enabling a user to download and play games or music, a service for enabling a user to directly access to Internet and to do web surfing, a service for facilitating the input of Internet addresses, or the like. These services implement the general functions of the mobile terminal in which networking is implemented using the data communication function of the mobile communication network. 
     Thirdly, there is a service using only it&#39;s own operation function and display function of a portable phone regardless of information exchange or networking. Examples of this service include a ‘set wallpaper’ service, unique user interfaces having a touch function, or the like. These services are mainly implemented by programs installed on a terminal by a terminal manufacturer. 
     Fourthly, there is a service having the purpose of purely representing and showing off a user oneself to a communication party rather than the purpose of information exchange. The fourth type of service is similar to the first type of service with respect to its system, their particular purposes are different from each other. Representatives of this type of services include a “color ring service” for enabling a party that makes a phone call to a user to listen to music previously selected by the user instead of a dial tone and a “lettering service” for enabling a communication party to see a sentence previously selected by a user when making a phone call. 
     The fourth service is an attractive service in that which this service is not necessarily needed for human&#39;s life but satisfies human fundamental desires. This type of service is well utilized actually, and a good revenue source for a service provider. 
     However, existing services have considerable limitations in the time point and period of expression due to the limitations of theirs ideas. For example, in the color ring service, music is replaced with a dial tone, so that when a party receives a call, the music stops to play. In the lettering service, the sentence is shown only during waiting for response to a call. Such limitations act to considerably restrict the enrichment of expression data, such as music or sentences. 
     Furthermore, the expression data does not perform interaction due to limitations in expression time, such as during origination or reception of a call, and therefore is output in a unilateral expression method so that interaction with the expression data as the user controls application programs is impossible. 
     These services have been developed to transmit multimedia data besides a simple sound or text but limitations in the above-described expression time, period and interaction are still maintained. 
     Meanwhile, these services which are performed in a server within a mobile communication network system have a problem in that the extension or modification in the mobile communication network system are needed in order for the improvement and extension of functionality or introduction of new ideas, thereby causing the consumption of great expense.

     BEST MODE 
     Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 
       FIG. 1  is a configuration diagram schematically showing the configuration of a system for providing a multimedia object linked to mobile communication networks according to an embodiment of the present invention. 
     Referring to  FIG. 1 , in the system for providing a multimedia object according to the present invention, a user mobile device  100 , an expression object server  200  and a user information device  300  are communicatively connected to each other via a data communication network  500 . 
     The user mobile device  100  is connected to a voice communication network  600  so as to perform voice communication with another user&#39;s mobile device via the voice communication network  600 . 
     An expression object processor  120  is installed or mounted in the user mobile device  100 , and an expression object editor  310  is installed in the user information device  300 . 
     In this case, the data communication network  500  includes wired high speed Internet, such as LAN, xDSL, Cable, or the like, wireless LAN, telephone modem, mobile communication, data communication network. Furthermore, the user mobile device  100  includes all personal mobile communication terminals which can establish voice communication regardless of the kinds of devices, such as a portable phone, PDA or the like, and be connected to the data communication network via wired or wireless access during the voice communication. 
     The user information device  300  includes all information devices which can be connected to the data communication network via wired or wireless access regardless of the kinds of devices, such as a portable phcine, PDA, PC or the like, and operate the expression object editor  310 . 
     Meanwhile, the voice communication network  600  includes all types of network networks which establish voice communication with the user mobile device  100 . In a case where the user mobile device  100  uses the data communication network during voice communication, the voice communication network  600  is identical to the data communication network  500 . 
     The expression object processor  120  embedded or installed in the user mobile device  100  outputs the expression object  122  received from the expression object server  200  or stored in an expression object cache  124  to the screen of the mobile device and other output devices in response to an expression object output initiation event. 
     A communication unit  110  for detecting a call request signal and a telephone number received from the voice communication network  600  is provided in the user mobile device  100 . 
     The user information device  300  includes the expression object editor  310  which edits the expression object  122  that a user intends to show to a communication party and transmits it to the expression object server  200 . In this case, the expression object editor  310  performs a function of receiving and editing the expression object  122  stored in the expression object storage  220  of the expression object server  200  and transmitting it back to the expression object server  200 , and a function of outputting the edited expression object  122  to the user information device  300  in a format to be actually seen by the communication party. 
     The expression object server  200  includes an expression object searcher  210  which searches for and extracts the expression object  122  from the expression object storage  220  and transmits it to the expression object processor  120  when the expression object processor  120  of the user mobile device  100  requests the expression object  122 . 
     Furthermore, the expression object server  200  functions to receive the expression object  122  edited by the expression object editor  310  of the user information device  300  and store it in the expression object storage  220 . In this case, an RDBMS (relational database management system) may be used to search for the expression object  122  for efficiency in a case where a number of users exist. 
     Several expression objects  122  may be exist for a user as described above, so that different expression objects  122  may be provided according to called parties or additional information, such as time, day, the locations of the called parties, or the like. 
     In order to provide different expression objects  122  depending on called parties, telephone number data transmitted to the expression object searcher  210  must include not only the telephone number of a communication party, but also the telephone number of a calling party. 
     In contrast, in the case where a system is configured such that a single expression object  122  exists for a user, only the telephone number of a communication party is to be transmitted. In the case in which additional information, such as time, day, the locations of called parties, or the like is used, the corresponding additional information is to be additionally transmitted, and the expression object server  200  may process partial information, such as day or the like by itself. 
     Furthermore, the expression object server  200  is forced to be connected to general networks coupled to mobile communication networks or wireless communication networks and the mobile device and the expression object server are force to perform general client and server operations respectively, so that the system according to the present invention can be established without extension or modification in an existing mobile communication network. 
     The expression object server  200  may be divided into two types of separate servers for playing different roles. 
     The first server is an expression object search server. The expression object search server includes the expression object searcher  210  which extracts information about access to the expression objects stored in the expression object server based on telephone numbers and other additional information. The second server is an expression object storage server. The expression object storage server includes the expression object storage  220 . 
     In this case, two methods for receiving the expression object  122  by the user mobile device  100  are possible. 
     According to the first method, the user mobile device  100  accesses to the expression object search server and receives the information about access to the expression object including the address of the expression object storage server, and accesses to a suitable expression object storage server based on the information to receive the expression object. 
     According to the second method, the expression object search server plays the role of a relay server which internally accesses to the expression object storage server to receive the expression object  122  and transmits it to the user mobile device  100 . In this method, the user mobile device  100  is provided with virtually integrated server functions, so that the user mobile device  100  completely recognizes the corresponding integrated server functions as the expression object server  200  and performs its operation. 
     Meanwhile, unlike that the expression object server  200  is divided into several servers according to its roles as described above, it is possible to provide several of one logical expression object server  200 . In this case, the expression object processor  120  of the user mobile device  100  and the expression object editor  310  of the user information device  200  may be connected to appropriate one of these expression object servers  20  to transmit the expression object  122 . In this case, three ways to select the expression object server  200  are possible. 
     The first way is that the expression object processor  120  and the expression object editor  310  directly select one according to a predetermined rule, for example, a remainder value resulting from division of the value of the last few digits of the telephone number of the communication party by a specific number. 
     The second way is that a separate selection server is provided in the expression object server  200 , and the expression object processor  120  and the expression object editor  310  access to the selection server to receive the selection results. 
     The third way is that the expression object server  29  is transparently configured in parallel using an address sharing system and a load balancing system, and expression object processor  120  and the expression object editor  310  access to a corresponding shared address. 
     Meanwhile, in the case where the expression object server  200  is divided into two types of servers according to its roles and the user mobile device  100  is directly connected to the respective server, that is, the address of the expression object storage server is included in the information about access to the expression object, the expression object storage servers may be configured by several servers having independent addresses without particular limitations. 
     For reference, methods to divide the expression object server  200  as described above are details to be implemented and the core ideas of the present invention can be maintained regardless of the methods. Accordingly, although the division method is modified, it is impossible to depart from the scope of the present invention as long as it provides functions identical to those of the system according to the present invention. 
     MODE FOR INVENTION  
       FIG. 2  is a configuration diagram schematically showing the internal configuration of a user mobile device according to an embodiment of the present invention. 
     Referring to  FIG. 2 , the user mobile device  100  includes a communication unit  110 , an expression object processor  120 , a control unit  130 , an input unit  140  and an output unit  150 . 
     The communication unit  110  detects originated or terminated calls related to voice communication. Furthermore, the communication unit  110  transmits and receives voice signals or multimedia data related to mobile communication via mobile communication networks. In this case, a detection unit for detecting originated or terminated calls related to voice communication may be configured separately from the communication unit  110 . 
     In addition, the communication unit  110  includes a mobile communication module which can communicate with CDMA 1× EV-DO networks, WCDMA networks, HSDPA networks, HSUPA networks or Wibro networks. 
     The expression object processor  120  functions to output the multimedia expression object received from the expression object server  200  to the output unit  150 . In this case, the expression object processor  120  may be included in the control unit  130  or may be separately configured to output the multimedia expression object to the control unit  130 . 
     In addition, the expression object processor  120  may be a module included in the system software of the user mobile device or an application program running in application program running environment. In both cases, the expression object processor  120  performs operations in response to an event related to an originated or terminated call provided by the hardware or system software of the mobile device. Accordingly, the expression object processor  120  may be initiated at a time point at which the event occurs and perform the above-described operations or may run quietly in the background, and when the event is received, perform the above-described operations. 
     When the originated or terminated call related to voice communication by the communication unit  110 , the control unit  130  extracts a telephone number from the originated or terminated call, and requests the multimedia expression object corresponding to the extracted telephone number from the expression object server  200  to control the reception of the multimedia expression object corresponding to the telephone number from the expression object server  200 . Furthermore, the control unit  130  performs control such that the multimedia expression object is output to the output unit  150  via the expression object processor  120 . As a result, the expression object processor  120  may be separately configured as in  FIG. 1 , but may be included in the control unit  130 . 
     The input unit  140  is for inputting a command for voice communication or a telephone number for voice communication. For this, the input unit  140  includes a plurality of buttons with letters, numbers and symbols. 
     The output unit  150  is a device for outputting the multimedia expression objects, and includes a screen output device for outputting the multimedia expression objects onto a screen and a sound output device for outputting sound, and a vibration output device for outputting vibrations. 
       FIG. 3  is a configuration diagram schematically showing the internal configuration of an expression object server according to an embodiment of the present invention. 
     Referring to  FIG. 3 , the expression object server  200  according to the present invention includes the expression object searcher  210 , the expression object storage  220  and the communication unit  240 . 
     The expression object searcher  210  searches for the multimedia expression object corresponding to the telephone number received from the user mobile device  100  in the expression object storage  220 . 
     The expression object storage  220  stores the telephone number of the user mobile device  100  and its corresponding multimedia expression object. 
     In this case, the multimedia expression object includes sense information, such as sight, hearing and touch which can be expressed by the user mobile device  100  and one or more among user interface objects which can interact with a user to derive corresponding results. 
     Furthermore, the multimedia expression objects include still images including a character string or a photograph, moving images, music and vibration data and are output via the screen output device, the sound output device, or the vibration output device of the user mobile device  100 . 
     In addition, the multimedia expression objects include interaction objects including buttons, icons, or menus. 
     Furthermore, a number of telephone numbers may correspond to one multimedia expression object. 
     In addition, the multimedia expression objects may include machine codes executable in the user mobile device  100  or script codes executable in the script engine of the user mobile device  100 . 
     When the control unit  230  receives a request for the multimedia expression object from the user mobile device  100 , the control unit  230  performs control to search for the multimedia expression object corresponding to a related telephone number in the expression object storage  220  via the expression object searcher  210 , and to transmit the found multimedia expression object to the user mobile device  100 . 
     The communication unit  240  communicates with the user mobile device  100  through the data communication network  500 . 
       FIG. 4  is a diagram showing a method for providing a multimedia object linked to mobile communication networks according to an embodiment of the present invention. 
     In embodiments of the present invention, it is assumed that user A&#39;s mobile device makes a phone call to user B&#39;s mobile device of user B. 
     Referring to  FIG. 4 , first of all, user A&#39;s mobile device  100  attempts to make a phone call to user B&#39;s mobile device (S 400 ). 
     In this case, the operation systems or communication units  110  of user A&#39;s mobile device and user B&#39;s mobile device deliver a call attempt event to the expression object processor  120  (S 405 ). 
     In this case, the event delivery is abstract idea. In particular, the expression object processor  120  starts to perform operations related to the call attempt event in the following two ways. 
     Firstly, the expression object processor  120  always runs in the background in the user mobile device  100 , and when an event message delivered by the operating system or the communication unit  110  upon call attempt is received, starts to perform its operations. 
     Secondly, environment is set such that the operating system or the communication unit  110  of the user mobile device  100  operates the expression object processor  120  upon occurrence of the call attempt event and, thereafter, when a related event occurs, the expression object processor  120  is operated to start to perform its operations according to the set environment. 
     After delivery of the event, the operating system or the communication unit  110  and the expression object processor  120  performs their tasks in parallel regardless of their situations. 
     The operating system or communication unit  110  of user B&#39;s mobile device which received the call establishes voice communication with user A&#39;s mobile device  100  (S 410 ). Thereafter, user A&#39;s mobile device  100  and user B&#39;s mobile device perform conventional voice communication (S 415 ). 
     Meanwhile, the expression object processors  120  of both user mobile devices, which start to perform voice communication, independently proceed to output the expression object of the communication party. In  FIG. 4 , it is shown that the expression object processor  120  of user A&#39;s mobile device  100  performs its operations earlier than the expression object processor of user B&#39;s mobile device, but this is for showing that the processors need not to simultaneously perform their operations, so that user A&#39;s mobile device  100  does not necessarily first perform its operation. Actually, depending on the performance of the respective user mobile devices  100 , network environment, or whether the expression object cache  124  is hit or not, theirs processing speeds may vary, and, as a result, a time point at which the multimedia expression object  122  is output is determined. 
     The expression object processor  120  extracts a telephone number and other information from event data and other environment of the user mobile device  100  (S 420 ). Furthermore, a message requesting the multimedia expression object  122  of the communication party is transmitted to the expression object server  200  based on the extracted data (S 425 ). 
     When the message requesting the multimedia expression object is received, the expression object server  200  searches for appropriate multimedia expression objects  122  corresponding to the telephone numbers via the expression object searcher  210  and transmits the found multimedia expression objects  122  to the user mobile terminals respectively (S 430 ). 
     In this case, when what is matched with a current request exists in the expression object cache  140  previously stored prior to occurrence of actual transmission, the expression object processor  120  may use the expression object cache  124  matched with the current request without reception from the expression object server  200 . This procedure is omitted from  FIG. 4 . 
     In the user mobile device  100 , the expression object processor  120  outputs the multimedia expression objects received from the expression object server  200  to the output unit  150  (S 435 ). 
     Accordingly, the user interacts with the multimedia expression object output by the output unit  150  while talking over the telephone (S 440 ). 
     In this case, the multimedia expression object includes interaction objects including buttons, icons, menus and the user mobile device may output various expression results while interacting with the user via the interaction objects. 
     In this case, the amount of the multimedia expression object is large, so that there are many cases in which transmission is inefficient. Therefore, when the multimedia expression object has been once received in the user mobile device, the multimedia expression object is cached in a storage device and is re-used. 
     Furthermore, the multimedia expression objects are composed of multimedia including a still image, such as a character string or a photograph, moving images, music, vibration data, or the like, and are output via the screen and sound output device, the vibration output device, or the like of the user mobile device. 
     In the present invention, the multimedia expression object is output at the time of originating a call or receiving a call, in the middle of a call, or at the end of a call, so that the interaction can be made for sufficient time. Furthermore, there is a problem in that a user does not sufficiently see the output of the multimedia expression object because the user holds the mobile device in contact with his or her ear during voice communication. However, in the present invention, the user can use the mobile device in the posture that the user takes to see the screen of the mobile device through functions, such as DMB viewing, music listening, video communication or the like. 
     The whole of the multimedia expression object or ancillary data, such as moving images, constituting it may have data formats specialized for services and may have standard data formats, such as Jpeg, MP3, H.264, XML or SVG. The specialized data formats have an advantage in that they can be optimized for corresponding services and mobile devices and the standard data formats have an advantage of using techniques verified in related fields. 
     The multimedia expression object may include indirect data, such as URL, referring to external data besides direct data. In this case, the expression object processor  120  accesses to a corresponding external data address and receives the data. 
     One multimedia expression object may be prepared commonly for all communication parties of a corresponding user, and a separate expression object may be also prepared for each classification when communication parties are classified according to the user&#39;s desires. In the latter case, the preparation loads of the user increases, but there is an advantage in that the specialized and appropriate expression for communication parties is possible. 
     Furthermore, separate multimedia expression object may be prepared according to not only communication parties but also additional information, such as time, day, the locations of the communication parties, or the like. In this case, corresponding additional information must be provide upon search of the multimedia expression object, and the expression object server  200  applies the corresponding additional information to the search of the multimedia expression object. 
     Furthermore, one multimedia expression object may correspond to a number of telephone numbers. This is available in the case where a user has several mobile devices. 
     The multimedia expression object may be manufactured directly by a user, but this is not easy because of limitations in general users&#39; creativity and aesthetic sense. Therefore, for the ancillary data constituting the multimedia expression object, basic data, for example, beautiful background images or the like, available in many cases may be provided by a service provider through various accounting systems. Furthermore, a service for organizing ancillary data, for example, the own photograph of a user, provided by the user and basic ancillary data provided by the service provider in an expert level may be provided. 
     The spatial composition of multiple data related to images of the multimedia expression objects, that is, an expressed screen image is output onto the screen of the mobile device of a communication party as arranged by the user preparing corresponding data, thereby maximally reflecting the original intension of the user. 
     However, the sizes of the screens of the mobile devices are various, so that there is a case in which the screen image is not output as arranged by the user. In this case, an original expressed screen may be expended or scaled down to match with the size of the screen of the mobile device of communication party. When the original expressed screen is larger than the size of the screen, it is possible to perform scroll through a scroll bar or drag. Alternatively it is possible to appropriately move the locations of multiple data according to a ratio between the sizes of the original expressed screen and the screen of the mobile device. In order to minimize the re-arrangement of the multimedia expression objects, when the user manufactures a preset multimedia expression object, the expression object editor may notify the size of the screen of the mobile device of a corresponding communication party. The sizes of the screens of respective mobile devices may be stored by transmitting corresponding information to the expression object server  200  when respective users perform registration for usage of the system according to the present invention, and the expression object editor  310  may receives this information from the expression object server  200 . 
     Thereafter, when the voice communication is terminated (S 445 ), a call termination event is delivered from the communication unit  110  to the expression object processor  120  (S 450 ). 
     In this case, the expression object processor  120  stops to (S 455 ) or continues to output of the multimedia expression object  122  according to a user&#39;s request or environment settings. 
     Although the output and interaction of the expression object are described with relation to the call attempt event in  FIG. 4 , the output sequence of the expression object similar to the above-described is possible for other events besides the call attempt event. 
     The present invention is similar to the case where a user registers the photograph or other information of a corresponding telephone number&#39;s owner in the phone book of the user&#39;s mobile device and when an originated or terminated call event occurs in the user&#39;s mobile device, the registered photograph or other information is output on the user&#39;s mobile device. However, the present invention is fundamentally different from the above case in that expression objects set by a communication party not a user are output on the user&#39;s mobile device, thereby implementing a system for satisfying the user&#39;s desires to show and flaunt the user to the communication party. Since self-expression and its accompanying decorations are for being shown to other people, a user more actively makes an investment to improve the quality of expression objects to be shown to a party rather than expression objects used in the user&#39;s own mobile device, which will be the marketing potential of the service implemented by the present invention. 
     Meanwhile, besides time points related to a call, the expression objects of respective users may be output to other users to be seen as follows. 
     Firstly, as described above, the mobile device may continue to output the expression object after a call has been terminated and may stop to output expression object according to a separate event, such as a stop commend from a user. 
     Secondly, regardless of a call, the mobile device may output the expression object for the telephone number of a party related to corresponding message transmission when a message is received or transmitted by a SMS system or a system similar thereto. 
     Thirdly, after the input of a telephone number, it is possible to start to receive and output the expression object rather than to establish voice communication. 
     There is a case where a user does not want to see the expression object of a party depending on communication parties. Therefore, similarly to a system of selectively receiving a call after the display of a caller&#39;s identification, only basic information, such as a caller&#39;s name and telephone number may be first displayed on a screen and a user interface component, such as a button for the display of the expression object may be then arranged therebelow, so that when the user interface component is clicked, the expression object of the communication party may be output. 
     In the case where the system according to the present invention is provided as a service, two types of services are provided depending on flexibility and expansibility as follows. 
     The first service is a service of providing an expression object processor which previously defines the types of ancillary data constituting an expression object and outputs only the expression object composed of corresponding type of ancillary data. 
     The second service is a service in which executable objects are included as the ancillary data of expression objects, and the expression object processor executes a corresponding object by interacting with the corresponding object via API (Application Program Interface), so that a separate service provider or a developer manufactures or adds executable objects having such a type, thereby extending the function of the expression object processor. In this case, the addition of the expression objects may be made without modification in the mobile device and the expression data server. In this service, a separate service provider can participate in this service even after initiation of the service and suggest various supplementary features and business models, thereby creating markets. 
     As described above, the present invention provides a system and a method for providing a multimedia object linked to a mobile communication network, in which a user transmits a multimedia expression object he or she has set up to the terminal of a communication party in a call via a data communication network so as to make the object displayed on the terminal at the time of originating a call or receiving a call, in the middle of a call, or at the end of a call and to allow an interaction with the multimedia expression object displayed on the terminal. 
     Although the exemplary embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. Accordingly, the scope of the present invention should not be limited to the above-described embodiments but should be determined by not only the appended claims but also the equivalents thereof.
