International messaging center, local messaging gateway, download center, mobile communication terminal and system for international message transmission and reception using mobile communication network {GLOBAL MESSAGING CENTER, LOCAL MESSAGING GATEWAY, DOWNLOAD CENTER AND SYSTEM FOR GLOBAL MESSAGING TRANSMMISSION}

The present invention relates to a message transmission and reception system using a mobile communication data network, and more particularly, to international message transmission and reception using a mobile communication data network to transmit and receive a message without being restricted by different heterogeneous mobile communication networks and languages. The present invention relates to a global messaging center (GMC), a local messaging gateway (LMG), a download center, a mobile communication terminal, and a system.

Recently, as overseas travel has increased and mobile communication terminal's automatic roaming has been activated due to the development of mobile communication terminals, the number of users who use roaming services by going abroad while carrying mobile communication terminals used by users is increasing. In this case, a typical method of transmitting a roaming message from a foreign user to a domestic user using a mobile communication terminal having a roaming service function is an SMS transmission method using an overseas roaming service of a mobile communication company.

1 is a block diagram of a mobile communication system for a message transmission service, such as SMS of a mobile communication terminal having a foreign roaming service of the prior art described above.

Referring to FIG. 1, a message transmission service such as an SMS of a mobile communication terminal equipped with an overseas roaming service in the prior art is as follows.

First, when a mobile subscriber of state B moves to country A, the mobile terminal 1 with roaming service function is provided to a mobile communication terminal 1 of state B subscriber in country A. When the send button is pressed, the message created in the caller's mobile communication terminal 1 is transferred to the caller's subscriber carrier's network (c) of the country B via the country A mobile communication network (a) and the international roaming network (b). In the caller-subscribed mobile network (c) in the country B that received the message, the message is transmitted to the subscriber-subscribed mobile communication network (d), and the subscriber-subscribed mobile communication network (d) transmits the message to the receiver's mobile terminal ( 2), the message transmitted by the user located in the country A using the sender's mobile terminal 1 is transmitted to the mobile communication terminal 2 of the receiver located in the country B.

In the case of the message transmission method using the roaming service between countries in the mobile communication network in the prior art as described above, the sender's mobile communication terminal 1 should be subscribed to the roaming service of the mobile communication company, and the receiver's mobile communication terminal 2 ) Shall also be a mobile communication terminal (2) subscribed to a mobile carrier of the mobile communication network of station B.

In the international message transmission method using a mobile communication terminal between countries of the prior art as described above, when transmitting and receiving a message between mobile communication terminals using different languages, it is common to transmit a message using only English and specific characters, not the corresponding language. In addition to the method of transmitting the image to the MMS (Multimedia Messaging Service) by the image, and in addition, between the mobile phone using a heterogeneous language as in the "Method for delivering short messages between countries" of Korean Patent Publication No. 2007-0093701 The following shows how to install and use a foreign language character input program that supports the language.

However, the aforementioned method for transmitting a text message of a mobile terminal between countries in the prior art provides a method of transmitting a message (eg, SMS) to a subscriber of a mobile carrier in a visiting country using a roaming service in a visiting country abroad. It does not have the problem.

In addition, the above-described method for transmitting a text message in a mobile communication terminal between countries of the prior art is limited to a certain size (for example, 80 bytes), as described above, the sender's mobile communication terminal 1 and The receiver's mobile communication terminal 2 becomes inflexible in terms of the language used and the type and size of the transmitted message.

In addition, the above-described method for transmitting a text message of a mobile communication terminal between countries in the prior art is a problem that the communication cost is expensive because it simultaneously goes through a message transmission network (for example, SMS network) included in the mobile communication network of the receiving country and the calling country mobile carrier. There is.

In addition, in order to transmit a text message of a mobile communication terminal between countries of the prior art described above, the mobile communication terminal should download and execute a platform application VM (Virtue Machine) having a function of providing a message transmission service between countries. When running the platform application VM (Virtue Machine), run the platform application manager by pressing a specific key (for example, Nate Key for SKT) on the standby screen of the mobile communication terminal, and then select a menu to select the downloaded platform application. By selecting and executing the application to be executed among the platform applications appearing in the menu, a number of key manipulations are required, which makes the message transmission process cumbersome. In the case of a foreign language character input program used for international message transmission, each language not really Since the platform application VM used must be installed and used separately, there is a problem of occupying the storage space of the mobile communication terminal with inconvenience.

As shown in Figures 2 and 3, the system to which the international message transmission and reception system using the mobile communication data network according to an embodiment of the present invention is applied is a message applied in the country-specific mobile communication network of the user of the A and B stations. DWNC (410, 420) that provides the application and the language pack (DLL) for the download request for the application and the user's language pack (DLL), A and B station message sending terminal (110, 120) and A and B stations Receiving terminals 110a and 120a, station A's GMC 210 and station B's GMC 220 as GMCs for controlling message transmission between countries, station A's LMG 310 providing message transmission services in a mobile communication network in a specific country. ) And B station LMG (320).

The GMCs 210 and 220 determine a transmission path of a message transmitted between countries and transfer the message to the LMG of the country in which the receiving terminals 110a and 120a are located, as shown in FIG. 3. Routing tables 213 and 223 for storing mobile communication network information for routing; A routing module (211, 221) for performing routing for transmitting and receiving a message transmitted and received using the mobile communication network information of the routing table (213) to the destination GMC (210, 220) or LMG (310, 320); And a message database (MSG DB) 212, 222 for storing message information transmitted and received.

The GMC (210, 220) having the above-described configuration receives a message from the calling terminal (110, 120) when the receiving terminal (110a, 120a) exists in another country with reference to the receiving number GMC (210, 220) of the corresponding country If the receiving terminal (110a, 120a) exists in the same country as the sending terminal (110, 120) and transmits the message to the LMG (310, 320).

As shown in FIG. 3, the LMGs 310 and 320 receive a message from the GMCs 210 and 220 and comply with a rule negotiated with a message service provider (IPTV, DTV, IP-Phone, mobile carrier, etc.). A conversion module 311 for performing message transfer protocol conversion accordingly; A conversion message database (hereinafter referred to as MSG DB) 312 and 322 which stores a result of performing the conversion module 311 (including a message: MSG) to prevent the loss of messages; A distribution module (313, 323) for distributing the converted MSG to message service provider systems (610, 620) to which the receiving terminals (110, 120) are subscribed; And a carrier table (314, 324) having a subscriber station number and a message service provider system information for relaying transmission and reception of messages.

LMG (310, 320) having the above-described configuration receives the message from the GMC (210, 220), and the message transmission protocol in accordance with the rules negotiated with a message service provider (IPTV, DTV, IP-Phone, mobile carrier, etc.) After the conversion is performed, the message is stored in the conversion MSG DB to prevent the loss of the message, and then the message is transmitted to the message service provider systems 610 and 620 to which the receiving terminals 110a and 120a subscribe. At this time, after receiving a message transmission confirmation message (success / failure) from the message service provider system (610, 620) after transmitting the message to the message service provider system (610, 620) and deletes the message from the conversion MSG DB If it fails, extract the message from the converted MSG DB and retransmit. If the delivery confirmation message does not arrive for a certain time, the message is extracted from the converted MSG DB and retransmitted.

Next, the Download Center (DWNC) 410. 420 provides a message application (for Window, Linux, VM, etc.) and a specific language pack (DLL) to the terminals 110, 120, 110a, and 120a. A download center for downloading, which includes a version of a message application (platform application) executable in the terminals 110, 120, 110a, and 120a and a language pack (DLL) of various countries (character set, character input automata). While storing the link libraries (DLL-Dynamic Link Library), when there is a connection of the terminal (110, 120, 110a, 120a), it is possible to select a stored message application (platform application) version and a specific language pack (DLL) Shows the screen and transmits the selected version of the message application and language pack (DLL) to the connected terminal (MS: 110, 120, 110a, 120a).

In the above-described configuration, the terminals 110, 120, 110a, and 120a may be a mobile communication terminal (MS) such as a mobile phone (Cellular Phone), a PDA (Mobile Device), or a PC having a communication device interworking with a mobile communication network. As shown in FIG. 4, the terminal 110, 120, 110a, 120a determines whether or not the overseas roaming service, and the message transmission and reception country and language to determine the message application from the DWNC (410, 420) Downloading the language pack (DLL), and if there is a key input assigned to drive the message application for sending and receiving messages of the downloaded calling terminal (110, 120), the message application is automatically changed depending on whether or not the international roaming service, etc. AADM 540 to be executed by; Furthermore, the hardware and the native system software 500 of the mobile communication terminal, which is hardware of the mobile communication terminal and OEM software of the manufacturer; A platform 510 provided with WIPI / J2ME / Brew and the like; Dynamic link library (DLL) which additionally downloads the language pack (DLL) 521a to 521n including character sets of various countries and input automata, and is stored for use when the message application 530 is driven. Dynamic Link Library (520); A message application (MSG. Application) 530 for writing and confirming a message in a corresponding language using a language pack (DLL) 521a to 521n including a character set of various countries and an input automata; It is configured to include, when the message is transmitted and received by the AADM 540 determines whether the overseas roaming service overseas roaming or when the corresponding message application (platform application) according to the domestic use GMC (210) , 220 is configured to transmit and receive.

In this case, when the terminals 110, 110a, 120, and 120a are general mobile phones, as shown in FIG. 4, the control unit (MSM) 111 and the control unit 111 controlling driving of the mobile phone are called and driven. The storage unit 500 for storing the application selection module 540, the dynamic link library 520, and the message application 530, the key input unit 112 for receiving a user's control command, and the RF signal. The RF unit 113 for transmitting and receiving, the handset 114 for a call, the display unit 115 for displaying the driving information of the mobile phone may be configured to further include.

In the configuration of the terminals 110, 120, 110a, and 120b, the AADM 540 corresponds to a message service function key when the user inputs a message service function key when the terminals 110, 120, 110a, and 120b are general mobile phones. If the terminal determines whether the overseas roaming service is provided, and if the overseas roaming service is not provided, the message service is performed by operating a pre-stored message application operated when the mobile communication service is subscribed. In case of being provided, it is determined whether the message application used in the mobile communication network in the country of the overseas roaming service is provided. And a language pack (DLL) including a user's request character set and input automata (5). 12a to 512n) are downloaded and stored as a dynamic link library (DLL) (520).

At this time, the dynamic link library 520 is stored so that the message application 530 can use the language pack (DLL) (512a ~ 512n) AAAA 540 downloaded from the DWNC (410, 420).

The language packs (DLLs) 512a to 512n are configured to be commonly used by all the message applications 530 designated by regions, so that when one message application 530 is stored, message transmission and reception of a plurality of characters may be performed. It becomes possible.

That is, the AADM 540 controls the download of the message application and language pack (DLL) required for the mobile communication terminal and the operation of the appropriate message application. To this end, the message application is provided with an identifier (for example, an application ID) for identifying a service target area, and inserted into a header or code to configure the application selection module 540 to identify the message application.

Therefore, among the terminals 110, 120, 110a, and 120a of the present invention, the mobile communication terminal downloads and uses a message application 530 and a language pack (DLL) 512a to 512n, which are necessary only when used overseas, for each language. Compared to the conventional method of downloading and using character sets, input automata, and API (Application Programming Interface) used for message input and display, it enables efficient use of limited terminal storage space. One for all languages. The message application 530 can be used.

The message application 530 performs a message transmission and a message reception function so as to perform a message transmission / reception service applied to a mobile communication data network in a region where the mobile communication terminal is located among the terminals 110, 120, 110a and 120a. As described above, an identifier such as an application ID is assigned to each service target region, and is configured to use all language packs (DLLs) registered in the dynamic link library 520.

2 to 4 having the above-described configuration is applied to the international message transmission system of the present invention so that the terminal (110, 120, 110a, 120a) can freely transmit and receive messages between countries or domestic In addition, it is also possible to send and receive messages using various characters when sending and receiving messages between countries or in Korea.

Hereinafter, a process for transmitting and receiving a message in the international message transmission / reception system of the present invention will be described with reference to FIGS. 2 to 7.

5 is a flowchart illustrating a process for international message transmission in the above-described system of FIGS. 2 to 4 equipped with an international message transmission system of the present invention.

First, in order to receive the international message transmission / reception service provided by the present invention, message applications are given an identifier such as an application ID for identifying a region to which the message application is applied or a mobile communication network. The region or application ID to which such an application is applied may have a structure inserted into a code or a header, and may be registered and stored in the download centers 410 and 420 or may be provided with a download service in a mobile communication network subscribed to by a mobile communication terminal. At the time of shipment, the mobile station is pre-installed on the mobile communication terminal subscribed to the mobile communication company of the calling terminal (110, 120) and the receiving terminal (110a, 120a).

Thereafter, a procedure for performing transmission and reception of an international message according to the present invention is performed. As shown in FIG. 5, when a user inputs a key assigned to the message application 530 for message transmission or confirmation of a received message (S10). In step S20, the application selection module 540 determines whether the calling terminal 110 or 120 receives the roaming service.

As a result of the determination in S20, when the calling terminal 110 or 120 is provided with the roaming service, information on the mobile communication network currently providing the roaming service and the message application ID previously installed in the calling terminal 110 and 120, and the corresponding ID. It is determined whether the message application (hereinafter referred to as a roaming message application) that can be used in the mobile communication network currently provided with the roaming service is installed in the calling terminal 110 and 120 by checking the mobile communication network information allocated to the mobile communication network information (S30). .

As a result of the determination in step S30, when the roaming message application is not installed in the calling terminal 110 or 120, the application selection module 540 accesses the download centers 410 and 420 to download and install the roaming message application (S40). After the roaming message application is installed, the application selection module 540 transmits the ID of the installed roaming message application to the platform core of the controller 111 to request driving (S50).

The control unit 111 receives the driving request in step S50 drives the platform application corresponding to the message application ID.

On the contrary, if the current calling terminal 110 or 120 is not provided with the roaming service as a result of the determination in step S20, the application shunt module 540 may perform a message transmission / reception function in the subscribed mobile communication network of the calling terminal 110 or 120. In order to execute the message application (OEM message application) previously provided to the calling terminal (110, 120) so as to (S70).

Next, when a suitable message application is executed in steps S60 and S70, the message application outputs a language pack list so that the user can select a language pack (DLL) (S80).

When the user searches a list of language packs output by the S80 process and selects a desired language pack (DLL), the application selection module 540 stores the language pack (DLL) selected by the user in the calling terminal (110, 120). Determine whether (S90).

If the desired language pack (DLL) is not stored as a result of the determination in step S90, the language pack download control command is input, and accordingly, the application selection module 540 accesses the download centers 410 and 420, and the user desires. Download the language pack (DLL) and save the language pack (DLL) as a dynamic link library (DLL) (530) (S100).

If the storage space is insufficient at the time of downloading the message application 530 and the language pack (DLL) (512a ~ 512n) in the message application download process of the S40 process and the language pack download process of the S100 of the above-described processing process, the application selection module 540 ) Informs the user that there is not enough storage space, delete the unused message applications 530 and language packs (DLLs) 512a through 512n, and delete the required message applications 530 and language packs (DLLs) 512a through 512n. Make it available for download.

Subsequently, if the language pack list selected by the user is stored as a result of the S90 process or the language pack download process is performed by the S100 process, the language pack (DLL) is registered in the dynamic link library 520. The message application 530 calls and drives the language pack (DLL) selected by the user from the dynamic link library 520, and then performs message transmission and reception (S110).

6 is a flowchart illustrating an international message transmission procedure.

As shown in FIG. 6, when a user wants to send a message while the international message transmission / reception message service of the present invention is provided, when the user inputs a message composition key, the message application uses the language of a specific country. The language pack list registered in the dynamic link library 520 is outputted so that a message can be written (S111).

At this time, the user determines whether the language pack DLL exists in the output language pack list, and if the language pack DLL exists, the user selects the language pack DLL (S113).

On the other hand, if the language pack (DLL) does not exist, the user requests the language pack download to the application selection module 540 by using an icon designated for downloading, and the application selection module 520 allows the user to download the target language. Prints a list of all language packs so that the pack (DLL) can be specified. If there is an input signal for selecting a specific language pack (DLL) by the user after the list of all language packs is output, the application selection module 540 accesses the download centers 410 and 420 to select the language pack (DLL) selected by the user. Download it (S114).

If the language pack (DLL) is selected for the user to compose a message in step S113, or if the language pack (DLL) is used for the user to compose the message in step S114, the message application being executed is the character of the language pack (DLL). By calling and loading sets and automata, the user can write messages in a specific country's language. In this case, the message application allows the user to select a specific item of the language pack selection menu to use a language other than the language basically supported by the calling terminal 110 and 120. When the language pack (DLL) is selected, the message application is selected. In operation 530, an input screen for inputting a corresponding language is displayed, and when a user inputs message data using the input screen, the input key is analyzed to create a message in a language of a specific country. When the user sends the message thus created, the calling terminal 110, 120 transmits the created message to the GMC (210 or 220) (S115).

The GMC 210 or 220 receiving the message in step S115 refers to a country in which the receiving terminals 110a and 120a are the same as the calling terminal 110 and 120 with reference to the receiving party number and the routing table 213 of the received message. It is judged whether or not it exists in or in another station (S116, S117).

If the receiving terminals 110a and 120a exist in the same country as the calling terminal 110 and 120 in the determination process, the message is transmitted to the LMG 310 or 320 in the same country (S118). The GMC 210 or 220 of the corresponding country is transmitted (S120), and the GMC 210 or 220 received through S120 transmits a message to the LMG 310 or 320 in the corresponding country (S121).

The LMG 310 or 320 receiving the message in steps S118 and S121 performs the entire process of the LMG 310 or 320 previously described with reference to FIG. 3, and the receiving terminal 110a or 120a joins through steps S119 and S122. The message service provider system 610 or 620 transmits the received message to the message receiving target terminal 110a or 120a, and transmits the transmission confirmation message to the LMG 310 or 620. To 320).

The message transmission method of the present invention as described above, the originating terminal (110, 120) is a user who is subscribed to a mobile carrier and is roaming abroad, if you send a message to a message recipient in a roaming country is not roaming service immediately without going through another country It is simpler than the conventional method of transmitting a message because a message is directly transmitted to a receiving terminal 110a or 120a using a data communication network of a mobile carrier of a corresponding country within a country, and a transmission cost is significantly lower because an international network is not used. Done.

7 is a flowchart illustrating a procedure of confirming a received message during the process of FIG. 5.

When the receiving terminal 110a or 120a according to the present invention receives the message and the user drives the message application 530 to confirm the received message, the application selection module 540 of the receiving terminal 110a or 120b The message list stored in the inbox is output so that the user selects a message written in a language of a specific country (S131).

When the user selects a specific message, the application selection module 540 determines whether a message application and a language pack (DLL) for outputting the corresponding message are installed (S132).

As a result of determining in step S132, if the message application or language pack (DLL) for outputting the message selected by the user is not installed, the corresponding message application or language pack (DLL) is downloaded by performing the process S40 or S100 of FIG. To install (S133).

When the mesh application and the language pack (DLL) are installed in step S132, and after the corresponding message application or the language pack (DLL) is downloaded and installed by the step S134, the corresponding message application is driven to operate the message corresponding language pack (DLL).
