The present invention relates to a terminal information sharing method for transmitting a multimedia message between heterogeneous systems. More specifically, when transmitting a multimedia message created at the calling terminal to a called terminal in another type of mobile communication system, information and calling of the called terminal using a multimedia service center and a multimedia conversion center without using a subscriber terminal database. It is determined whether the multimedia message from the terminal includes unrecognizable media, and if it contains unidentifiable media, the receiving multimedia service center or calling multimedia service center converts or reconstructs the multimedia message that can be confirmed by the receiving terminal. The present invention relates to a method of sharing terminal information for transmitting a multimedia message between heterogeneous systems.

With the rapid development of electronic engineering and communication engineering, mobile communication terminals have various functions. That is, with the rapid development of wireless communication and data communication technology, people can use not only voice calls but also Internet access, video communication and video message transmission using mobile communication terminals. Also, due to the rapid spread of mobile communication terminals, mobile communication terminals are becoming an essential means of communication in modern life, such that a great amount of communication between remote sites occurs through mobile communication terminals.

In recent years, not only the area or state where a call is available among the various functions of the mobile communication terminal, but also when the call connection is not made due to the case where the other party has left the mobile communication service area or the mobile terminal is turned off. Short message service (SMS) or voice message service (VMS) that can deliver a text message or voice message to the other party is widely used.

On the other hand, the short message service or voice message service is difficult to meet the various needs of the user because it transmits a simple text or voice message to the other party. As a result, multimedia messaging services (MMS) have recently been developed to satisfy the desire of mobile subscribers to transmit messages in multimedia forms such as pictures, images, and videos other than simple text or voice messages. It is a trend that is actively used. MMS refers to a messaging service that transmits and receives multimedia information by processing, converting, and selecting data in various formats to be suitable for various multimedia service environments. MMS provides a function of transmitting and receiving multimedia information and e-mail to various devices desired by the user, away from the limited integrated services based on text or voice provided by the conventional Unified Messaging Service (UMS).

Meanwhile, mobile communication service in Korea is provided by three companies, SK Telecom, KTF and LG Telecom. Each mobile service provider owns, operates, and manages a service support system supporting one or more of various mobile communication service methods such as cellular, PCS, CDMA, WCDMA, and 1x EV-DO methods. Each member subscribes to a mobile telecommunication service provider and receives a mobile telecommunication service provided by the corresponding company. Accordingly, when providing a voice call, a short message service, a voice message service, and an MMS service between heterogeneous systems through a mobile communication service company, the mobile communication system of the sender receives information of the called terminal through the mobile communication system of the receiver. You need to check.

The confirmation of the information on the called terminal includes information on the subscriber's telephone number of the receiving mobile communication service provider, the terminal's mobile identification number (MIN), the terminal's unique serial number (ESN), and the type of service. It should be checked through the receiving subscriber station database.

In addition, the mobile communication terminal is configured in hardware and software so that only the service of the mobile communication service company to which it belongs. That is, the hardware includes a chip for recognizing the mobile communication service system of the corresponding company, and the software includes an application for receiving the mobile communication service of the corresponding company.

Meanwhile, in order to receive the aforementioned MMS, the mobile communication terminal must have a program and hardware for displaying the received multimedia message. In other words, the mobile communication terminal receiving the multimedia message not only plays a text and voice, but also a video, photo, audio, pictogram, animated image, color text, background color, and background. It should include a function to play back multimedia messages created using images. A terminal without such a function not only can not receive the multimedia message but also can not play it.

Here, since the applications used by each mobile communication service provider are different, a multimedia message transmitted through another mobile communication system may not be played.

Accordingly, there is a demand for a technology that can easily reproduce a multimedia message transmitted through another mobile communication system and does not go through a complicated process of checking information of a receiving terminal through a subscriber terminal database of the corresponding mobile communication system.

In order to solve this problem, the present invention, when transmitting a multimedia message made in the calling terminal to the destination terminal in the other type of mobile communication system, the incoming call using the multimedia service center and the multimedia conversion center without using the subscriber terminal database It is determined whether the information of the terminal and the multimedia message from the calling terminal contain media that cannot be identified by the called terminal, and if it contains unidentifiable media, the multimedia that can be confirmed by the called terminal at the receiving multimedia service center or the calling multimedia service center.

The home location register (not shown) is a subscriber station database that stores a service profile about mobile subscriber information.

The transmission data core network 124 is a high-speed data service for providing a packet data communication service, an internet / intranet connection service, a virtual private network (VPN) connection service, a simple IP and a mobile IP service. , PPP (Point-to-Point Protocol) authentication, billing and packet compression.

The sending MMSC 130 is a core component of the MMS system including a sending MMS server 132, a sending media transcoding server (MTS) 134, and a sending MMS database 136. It performs message transmission and reception between different mobile communication systems. The transmitting MMSC 130 transmits the multimedia message received from the calling terminal 110 to the called terminal 170 through the Internet 140, the receiving MMSC 150, and the receiving mobile communication network 160.

Here, the transmitting MMS server 132 manages and controls the transmitting MTS 134 and the transmitting MMS database 136 so that multimedia messages can be transmitted between terminals located in the mobile system. The transmitting MTS 134 performs a function of converting multimedia data to each other. That is, for example, converting HTML (Hypertext Markup Language) text or the like into Extensible Markup Language (XML) text or the like, converting a WAV or MP3 audio file into a QCELP (Qualcomm Code Excited Linear Prediction) audio file or the like, or JPG ( Image files such as Joint Photographic Expert Group (GIF) and Graphic Interchange Format (GIF) are converted into simple image service (SIS) image files. Here, the multimedia data converted through the transmission MTS 134 is reconstructed into a new multimedia message through the transmission MMS server 132.

In addition, the sending MMS database 136 not only stores the multimedia message transmitted from the sending MMS server 132, but also the mobile identification number (MIN) and the mobile directory number (MDN) of the calling terminal belonging to the mobile communication service company on the sending side. ), Profile information of the terminal, and various service information available.

The Internet 140 refers to a global open computer network architecture that provides the TCP / IP protocol and various services that exist in the upper layers, namely HTTP, Telnet, FTP, DNS, SMTP, SNTP, NFS, and NIS. In addition, the Internet 140 is a path for transmitting the multimedia message received from the calling terminal 110 to the called terminal 170.

The receiving MMSC 150 also includes a receiving MMS server 152, a receiving media conversion server (MTS) 154, and a receiving MMS database 156, with each component transmitting MMS server 132 at the sending MMSC 130. ), And performs the same function as the transmitting MTS 134 and the transmitting MMS database 136. However, the reception MMSC 150 receives the multimedia message transmitted from the Internet 140 as opposed to the transmission MMSC 130 which transmits the multimedia message from the transmission mobile communication network 120 to the Internet 140. Through the transmission to the destination terminal 170.

When the multimedia message and the MDN of the called terminal 170 are transmitted through the Internet 140, the receiving MMS server 152 transmits the terminal information of the called terminal 170, the profile information of the user, and the like through the receiving MMS database 156. By checking the service information and the like, it is determined whether the transmitted multimedia message can be reproduced in the destination terminal 170.

When the receiving MTS 154 checks the terminal information of the called terminal 170 in the receiving MMS server 152, when the multimedia message includes the media that cannot be played in the called terminal 170, the receiving terminal receives the corresponding media. The unit 170 converts the media into playable media.

In this case, when the multimedia message includes media that cannot be converted in the reception MTS 154, media other than media that cannot be converted through the reception MTS 154 is converted, and media converted through the reception MMS server 152. Reconstruct multimedia message using only.

The receiving mobile communication network 160 also includes a receiving wireless base station 162, a mobile switching center (not shown), a receiving data core network (DCN) 164, and a home location register (HLR) (not shown). ), And its function is the same as the aforementioned transmission mobile communication network (120).

The destination terminal 170 receives and plays a multimedia message through the reception MMSC 150 using the reception mobile communication network 160. Therefore, the destination terminal 170 has an application for playing the received multimedia message.

2 is a flowchart illustrating a method of sharing terminal information for transmitting a multimedia message between heterogeneous systems according to an exemplary embodiment of the present invention.

In a terminal information sharing system for transmitting a multimedia message (MMS message) between heterogeneous systems described with reference to FIG. 1, a mobile subscriber, that is, a sender, creates an MMS message through a key manipulation of the calling terminal 110. At this time, the calling terminal 110 is equipped with a plurality of applications used in the subscribed mobile communication system, and composes a multimedia message using the mounted application. The created multimedia message is transmitted to the transmitting MMS server 132 using the transmitting mobile communication network 120 together with the MDN (Mobile Directory Number) of the called terminal 170 (S200).

The MMS server 132 that receives the multimedia message from the calling terminal 110 is connected to the mobile communication service company to which the called terminal 170 belongs and the called terminal 170 through the MDN of the called terminal 170 received together. Check the MMSC 150 (S210).

When the receiving MMSC 150 is confirmed, the transmitting MMS server 132 of the transmitting MMSC 130 transmits a Forward Request signal including the multimedia message and the MDN of the called terminal to the receiving MMS server 152 through the Internet 140 or a dedicated line. send. The receiving MMS server 152 transmits a Forward Response signal to the transmitting MMS server 132 as a response signal (S220).

The receiving MMS server 152 receiving the multimedia message and the MDN of the called terminal 170 from the sending MMS server 132 uses the MDN of the received called terminal 170 to store the called terminal (stored in the receiving MMS database 156). The terminal information, user profile information, and various service information of 170 are checked (S230).

The terminal information of the called terminal 170 is checked to determine whether the multimedia message received from the transmitting MMS server 132 includes media that the called terminal 170 cannot reproduce (S240).

As a result of checking the multimedia message, when the terminating terminal 170 includes unsupported media, the receiving MMSC 150 may format the terminating terminal 170 to play the unsupported media using the receiving MTS 154. Convert to. Alternatively, in order for the receiving MTS 154 to play the unsupported media in the destination terminal 170, a part including the unsupported media of the multimedia message is removed, and only the remaining part is in a format that the destination terminal 170 can play. It is also possible to convert to multimedia form and reconstruct the multimedia message via the receiving MMS server 152. Here, in the following description, the multimedia message reconstructed into the remaining parts except the unsupported media among the multimedia messages will be referred to as a 'reconstruction message' (S250).

However, in step S250, the receiving MTS 154 does not include a function of converting unsupported media, which the terminating terminal 170 cannot reproduce, from the multimedia message into a playable media, or the receiving MTS server (at the receiving MTS 154). When it is impossible to convert the multimedia message to be provided to the destination terminal 170 through the receiving MTS 154, such as failing to analyze the multimedia message transmitted from 132, or the generation of the reconfiguration message at the receiving MMS server 152 is impossible. (S260), the receiving MMS server 152 is a message indicating that the destination terminal 170 cannot play the delivered multimedia message, and through the receiving MTS server 132 to convert or receive the multimedia message through the MMS (152) An error message indicating that generation of the reconfiguration message is impossible is transmitted to the transmitting MMS server 132 together with the terminal information of the called terminal 170. In this case, the terminal information transmitted to the transmitting MMS server 132 includes a format, detailed profile information of the media that the terminating terminal 170 can accommodate, and an LCD resolution of the terminating terminal 170 (S270).

The transmitting MMS server 132, which has received a message indicating that the multimedia message of the called terminal 170 cannot be reproduced, an error message indicating that it cannot be converted or reconfigured, and terminal information of the called terminal 170, receives the multimedia through the transmitting MTS 134. The message is converted into a message form that the called terminal 170 can confirm. Of course, in this case as well, as in step S250, after removing the part including the unsupported media of the destination terminal 170 of the multimedia message and converting only the remaining part, it is also possible to generate a reconfiguration message using the transmitting MMS server 132. Possible (S280).

The MMS message whose form is changed by the transmitting MTS 134 or the reconfiguration message generated by the transmitting MMS server 132 is performed again through the step S220 transmitted to the receiving MMS server 152 through step S280.

During this process, if it is confirmed through the steps S240 and S260 that the multimedia message is configured that does not contain unrecognizable media in the destination terminal 170, the receiving MMS server 152 is the receiving mobile communication network 160 The converted or reconstructed multimedia message is transmitted to the called terminal 170 through S290.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.

As described above, according to the present invention, when transmitting a multimedia message between heterogeneous systems, when the multimedia message transmitted from the calling terminal includes a medium that cannot be confirmed by the called terminal, the multimedia message receiver checks the message. Or, the inconvenience that the called terminal user has to check a multimedia message by accessing a specific web page through the wired Internet disappears.                     

In addition, since the subscriber terminal database of the mobile communication service system is not used to check the terminal information of the called terminal, and the database of the multimedia messaging service center is used, traffic generation imposed on the mobile communication system in multimedia message transmission can be suppressed. It works.
