The SMSC 170 may transmit an SMS signal to the MSC 21 of the second mobile communication network 20 using the identified location information (S245), and the MSC 21 may transmit the SMS signal to the terminal 40. There is (S250).

When the SMS signal is received, the outbound roamer may check the translation of the short message transmitted through the terminal 40.

3 is a flowchart illustrating a process of providing a translation service according to an embodiment of the present invention. This embodiment also corresponds to a case where a translation service is provided to the outbound roaming terminal 40.

Processes S310 to S335 of FIG. 3 may be understood in the same manner as processes S210 to S235 of FIG. 2, and thus description thereof will be omitted.

When the translation is transmitted from the translator 201 (S335), the translation service providing server 160 may generate an image file including the translation (S340).

Thereafter, the translation service providing server 160 may transmit a multimedia message service (MMS) signal including the image file generated in step S340 to the MMSC 180 (S345). Here, the MMS signal may include a communication number of the terminal 40 as the called number.

The MMSC 180 may include a short message indicating that the multimedia message has been received, and may transmit an SMS signal including the communication number of the terminal 40 as the called number to the SMSC 170 (S350).

The SMSC 170 may confirm the location information of the terminal 40 to the HLR 150 using the called number of the SMS signal. The SMSC 170 may transmit an SMS signal to the MSC 21 of the second mobile communication network 20 using the confirmed location information (S355), and the MSC 21 may transmit the SMS signal to the terminal 40. There is (S355).

When the SMS signal is received, the terminal 40 may receive an image file including the translation from the MMSC 180 using the data call (S365). Outbound Romer will be able to use the translations contained in the image file. According to an embodiment of the present invention, processes S350 to S360 of FIG. 3 may be omitted, and a multimedia message may be automatically transmitted from the MMSC 180 to the terminal 40 in step S365.

In FIG. 2, a process of providing a translation using SMS has been described, and in FIG. 3, a process of providing a translation using MMS has been described. According to an embodiment of the present invention, when providing a translation service, one of SMS and MMS may be alternatively used according to the performance of the terminal 40. This will be described with reference to FIG. 4.

When the translation service request signal is transmitted from the SMSC 170, the translation service providing server 160 supports the language corresponding to the country where the outbound roamer is located (that is, the language used to prepare the translation) by the terminal 40. It may be determined whether or not (S410). When subscribing to a mobile communication service of the first mobile communication network 10, subscriber information of the subscriber may be managed by the HLR 150 or a separate server, not shown, and the subscriber information may include information on the type of the terminal used by the subscriber. It may include. Performance information for each type of terminal produced for each terminal manufacturer may be collected / managed by a specific device of the first mobile communication network 10. In the present specification, since the outbound roamer is a subscriber of the first mobile communication network 10, the translation service providing server 160 may check the performance information of the terminal 40 used by the outbound roamer in the above-described environment. Do.

As a result of the determination in step S410, if the terminal 40 supports the language used in the translation, the translation service providing server 160 may provide the translation to the terminal 40 using SMS as in the embodiment of FIG. 2 ( S420).

However, as a result of the determination of step S410, if the terminal 40 does not support the language used in the translation, since the terminal 40 will not properly display the translation to the user when using the SMS, the translation service providing server 160 As in the embodiment 3, the translation may be provided to the terminal 40 using the MMS (S430).

 5 is a flowchart illustrating a process of providing a translation service according to an embodiment of the present invention. This embodiment corresponds to a case where a translation service is provided to the inbound roaming terminal 40. In the present embodiment, the terminal 30 performs communication in the first mobile communication network 10.

When the terminal 30 roams to the first mobile communication network 10 and finishes registration of the location (S510), the GLR 140 may transmit an SMS signal including a short message introducing the translation service to the SMSC 170. There is (S515). The SMS signal may include the communication number of the terminal 30 as the called number.

The SMSC 170 may transmit an SMS signal to the MSC 130 (S520), and the MSC 130 may transmit an SMS signal to the terminal 30 (S525). When the terminal 30 receives the SMS signal, it can be seen that the inbound roamer can use the translation service in the first mobile communication network 10.

In order to use the translation service, the inbound Romer may use his terminal 30 to write a content that needs to be translated into a short message. In this case, the language input by the inbound roaming device to the terminal 30 is the native language of the inbound roaming (ie, the language corresponding to the country to which the second mobile communication network 20 to which the inbound roaming belongs) belongs.

Thereafter, when the inbound roamer inputs the communication number assigned for the translation service as the called number and instructs transmission of the short message, the terminal 30 sends an SMS signal including the short message written by the inbound roaming MSC 130. It may be transmitted to (S530).

If the first mobile communication network 10 is designed to send the SMS signal transmitted by the inbound roaming terminal 30 via the GLR 140, the MSC 130 may transmit the SMS signal to the GLR 140 (S535). .

Since the called number of the transmitted SMS signal is a communication number of the translation service providing server 160, the GLR 140 may transmit a translation service request signal to the translation service providing server 160 (S540). The translation service request signal may include a short message and a calling number included in the SMS signal. Although not shown, when the calling number of the SMS signal transmitted in step S535 is not the communication number of the translation service providing server 160, the GLR 140 transmits the SMS signal according to the calling number of the first mobile communication network 10. It may be transmitted to the SMSC 170 or forwarded to the second mobile communication network 20.

The translation service providing server 160 may know the country to which the second mobile communication network 20 subscribed by the inbound roamer through the calling number of the SMS signal, and through this, the short message included in the translation request signal may be written in any language. You can see if For example, the International Mobile Station Identity (IMSI) assigned as a communication number when subscribing to a Global System for Mobile communications (GSM) service includes a Mobile Country Code (MCC) that can identify a country to which a mobile communication network belongs. In this case, the translation service providing server 160 may recognize that the short message included in the translation request signal is written in a language corresponding to the country identified by the MCC.

Therefore, the translation service providing server 160 may notify the appropriate translator 501 of the translation work so that the short message included in the translation request signal can be translated into the language of the country to which the first mobile communication network 10 belongs ( S545).

The translator 501 may translate the short message into a language corresponding to the country to which the first mobile communication network 10 belongs (S550), and transmit the translated text of the translated content to the translation service providing server 160 (S555).

When the translation is received, the translation service providing server 160 may generate an image file including the translation (S560).

Thereafter, the translation service providing server 160 may transmit an MMS signal including the image file generated in step S560 to the MMSC 23 of the second mobile communication network 20 (S565). Here, the MMS signal may include a communication number of the terminal 30 as the called number. Of course, the translation service providing server 160 does not have to directly transmit the MMS signal to the MMSC 23, and the MMS signal may be transmitted from the translation service providing server 160 to the MMSC 23 via other devices. .

The MMSC 23 may transmit an SMS signal including a short message indicating that the multimedia message has been received to the GLR 140 of the first mobile communication network 10 (S570). The SMS signal transmitted in step S570 may include a communication number of the terminal 30 as the called number. In order to transmit the SMS signal, the MMSC 23 may inquire the HLR 22 of the location information of the terminal 30 and use it.

Thereafter, the SMS signal may be transmitted to the terminal 30 via the SMSC 170 and the MSC 130 (S575, S580, S585). When the SMS signal is received, the terminal 30 may receive an image file including a translation from the MMSC 180 using the data call (S590). The inbound Romer will be able to use the translations contained in the image file.

According to an embodiment of the present invention, processes S570 to S585 of FIG. 5 may be omitted, and a multimedia message may be automatically transmitted from the MMSC 23 to the terminal 30 in step S590. Of course, even in this case, the multimedia message may pass through other devices between the MMSC 23 and the terminal 30.

In addition, according to an embodiment of the present invention, an embodiment in which a translation service is provided to the inbound roaming terminal 30 using SMS is also possible. In this case, the translation service providing server 160 may transmit an SMS signal including the translation number and the called number to the SMSC 170 including the communication number of the terminal 30, and the SMS signal is transmitted to the terminal 30 via the MSC 130. ) May be sent.
