Before describing the present invention, a comparative example of the present invention will be described as follows. 1 is a diagram illustrating a method of providing a roaming guide message performed by a roaming guidance message system compared with the present invention. That is, FIG. 1 shows a call processing method of the roaming guide message.

1, the roaming information message system includes a home location register (HLR) 11, a short message service center (SMSC) 12, a gateway location register (GLR) 13, a roaming service control point (RSCP) (14), and a roaming terminal (15) which is a user terminal of an O / B roamer. The HLR 11, the SMSC 12, the GLR 13 and the RSCP 14 constitute a domestic WCDMA network such as a KT-WCDMA network and the roaming terminal 15 constitutes an overseas WCDMA network.

A call processing method of the roaming guide message shown in FIG. 1 will be described as follows.

The roaming terminal 15 can register (store or transmit) its own location information to the GLR 13 through communication with the GLR 13. [ Thereafter, the GLR 13 registers the location information of the roaming terminal 15 in the HLR 11. The GLR 13 then requests the RSCP 14 to register in the RSCP 14 the location information of the roaming terminal 15 transmitted (transmitted) from the GLR 13 using the CS_REG_REQ message.

When it is confirmed that the location registration of the roaming terminal 15 has been performed for the first time in the RSCP 14, the RSCP 14 transmits a roaming guide message corresponding to a region (country) or a carrier roaming the roaming terminal 15 to a short message client interface to the SMSC 12 to request the roaming terminal 15 to transmit a roaming announcement message which is a short message. Thereafter, the SMSC 12 transmits an acknowledgment response message (Ack) to the RSCP 14 in response to the transmission request of the RSCP 14.

The SMSC 12 transmits an acknowledgment message (Ack) to the roaming terminal 15, and then transmits (transmits) the roaming information message, which is a short message, to the roaming terminal 15 using the MT ForwardSM message. Then, the SMSC 12 reports the completion of delivery of the roaming announcement message, which is a short message, to the RSCP 14 after delivering a roaming announcement message, which is a short message, and the RSCP 14 transmits an acknowledgment message (Ack) (12). That is, the RSCP 14 receives StatusReport, which is a transmission result message defined in the SMCI standard, and manages the state of message transmission per subscriber.

The RSCP 14 stores the completion of transmission of the roaming announcement message to the subscriber DB of the RSCP 14 after transmitting the message (roaming announcement message), and then transmits the roaming announcement message to the same country and service provider (that is, The location registration of the roaming terminal 15 is completed, thereby preventing the redundant transmission of the roaming guide message. That is, since the RSCP 14 stores the transmission completion of the roaming guide message as described above in order to prevent the ping-pong message from being sent, the A-national carrier-B national carrier-A national carrier, or A national carrier -B National carrier-C country carrier -A It is possible to prevent duplicate transmission of location movement of country carrier case. In the RSCP 14, a roaming guidance message reception refusal setting may be registered for each subscriber who is a user of the roaming terminal 15.

Even if the SMSC 12 transmits the roaming guide message at the request of the RSCP 14, the RSCP 14 can transmit the location registration of the roaming terminal 15 through the communication company of another country or another carrier (other company of the same country) The SMSC 12 can control the SMSC 12 to transmit a roaming announcement message set for each of the countries.

The roaming information message includes only a short message, and the guidance message is configured as follows. The announcement message consists of roaming rate and roaming call center information message of the country concerned, and a message to provide embassy and consulate guidance in preparation for emergencies. These messages may be transmitted to the roaming terminal 15 of the customer at the same time with four to five messages at a time when the roaming terminal 15 is first registered in the visiting network of the visited station, so that the customer can not confirm the message.

FIG. 2 is a view for explaining a roaming guide message providing method performed by the roaming guide message providing system 100 according to an embodiment of the present invention. In addition, FIG. 2 may represent a call processing method for providing a roaming guide message.

Referring to FIG. 2, the roaming-guidance-message providing system 100 of the present invention includes a Home Location Register (HLR) 105, a Short Message Service Center (SMSC) 110, a GLR gateway location register) 115, an RSCP (Roaming Service Control Point) 120, an integrated platform 125 such as a KHF hub for your business (KHUB), and an O / B roamer and a roaming terminal 130 which is a user terminal of a roamer. The roaming guide message providing system 100 can provide a welcome LMS service, and the welcome LMS service can be provided to a foreign embassy contact, a consular call center contact information of the Ministry of Foreign Affairs and Trade, roaming call A roaming service announcement guide, a roaming usage guide guide, or a fee guidance to the roaming user immediately after entry into the SMS or LMS.

The HLR 105, the SMSC 110, the GLR 115, the RSCP 200 and the integration platform 125 are connected to a domestic Wide-Code Division Multiple Access (WCDMA) network, such as a WCDMA network of KT (korean telecommunication) And the roaming terminal 130 may be included in a foreign WCDMA network which is a visitor network or a visited network. The subscriber of the home network roams to the visited network and can receive the communication service.

The home network includes a mobile switching center (MSC) (not shown) for performing a central control function for processing a signal transmitted or received from each mobile telephone base station and adjusting the mobile telephone base station so as to operate efficiently, And a radio access network including a base station and a base station controller. The visiting network is an overseas network, and includes a home location register (HLR) (not shown), a short message service center (SMSC) (not shown), a gateway location register (GLR) (not shown), and a mobile switching center (Not shown), and the like. The home network refers to a network of a business operator contracted by the owner of the roaming terminal 130. The visiting network refers to a network of a business operator having a place where the owner of the roaming terminal 130 is located at the time of roaming .

The HLR 105 is a database that holds subscriber information as a location registration device of the mobile communication subscriber 130 and can store various information (location, profile, additional service, or status) of the mobile phone subscriber The mobile phone subscriber can provide basic functions necessary for a call connection including a text message connection, such as checking the current location using the subscriber information and checking the supplementary service when making a call attempt. The HLR 105 may provide routing information for the roaming terminal 130 using the location information of the roaming terminal 130 and the subscriber profile. That is, when the HLR 105 receives the routing information request for the roaming terminal 130 from the originating MSC of the home network, the HLR 105 uses the location information of the roaming terminal 130, And obtain the routing number from the destination MSC (MSC) and transmit it to the originating MSC (MSC).

The SMSC 110 is a system for a mobile communication service that enables sending and receiving a text message between mobile communication subscribers, and is capable of storing and transmitting a short message. The SMSC 110 transmits the SMS message to the roaming terminal 130 when the roaming information message determined by the RSCP 200 is a short message service (SMS) message.

The GLR 115 is a gateway location registration agent acting as a gateway of the location registration process of the roaming terminal 130 roaming from the home network to the visited network. It is a device that acts as a gateway when exchanging profiles such as subscriber location information of a network, subscriber status information and subscriber addition service information. The GLR 115 provides a function of converting a MAP (Mobile Application Part) message between devices, thereby minimizing modification of the network equipment for roaming. The GLR 115 registers location information of the roaming terminal 130 and registers the location information of the roaming terminal 130 in the HLR 105. The GLR 115 transmits a location registration request to the HLR 105 which receives the roaming terminal 130 and the RSCP 200 when the location registration request is received from the roaming terminal 130. [ The GLR 115 may download the subscriber profile from the HLR 105 and transmit the subscriber profile to the exchange of the visited network (MSC) and the RSCP 200. The subscriber profile may include intelligent network service trigger information (Global Title (GT) of RSCP 200, etc.) and a mobile identification number (MIN). The GLR 115 can relay the exchange of routing information between the HLR 105 and the exchange (MSC) of the visited network or between the HLR of the visited network and the exchange (MSC) of the home network.

The RSCP 200 is a roaming service control device that provides a roaming service based on an intelligent network between WCDMA networks. The RSCP 200 functions as an intelligent network server (SCP) of the roaming subscriber in cooperation with the GLR 115. The RSCP 200 provides the intelligent network service in conjunction with the MSC of the visited network based on the received subscriber profile (subscriber profile information). The RSCP 200 receives and registers (stores) the location information of the roaming terminal 130 from the GLR 115 and stores the terminal model name information of the roaming terminal 130 in which the location information is registered from the integration platform 125, (Or the type of the roaming guide message) corresponding to the terminal model name information and the supplementary service subscription information of the received roaming terminal 130 to the roaming terminal 130, (Set). The RSCP 200 may store the transmission completion information indicating that the roaming guide message is transmitted to the roaming terminal 130.

In addition, the RSCP 200 transmits the determined roaming information message and another roaming information message (for example, a roaming rate of a visiting country and a roaming information message regarding a roaming call center, or an embassy and consulate guidance providing message in preparation for an emergency situation) (Adjust or set) the transmission time (transmission time point) of the roaming information message transmitted to the roaming terminal 130 so that the transmission (sending) of the roaming information message is not performed. Therefore, according to the present invention, the user of the roaming terminal 130 can easily and accurately confirm the roaming guide message. In another embodiment of the present invention, the RSCP 200 may register a roaming guidance message reception rejection setting for each subscriber who is a user of the roaming terminal 130. [

In another embodiment of the present invention, the RSCP 200 can determine the roaming rate of the country (visiting country) and the roaming rate of the roaming call center, regardless of the terminal model name information and the supplementary service subscription information of the roaming terminal 130 (Sending time) of the roaming announcement message, which is a message for providing an embassy or consulate guide in preparation for an emergency or an emergency, to the SMSC 110. Since the SMSC 110 sequentially transmits the roaming information messages to the roaming terminal 130 at intervals of time according to the transmission timing, the roaming guiding messages may not be simultaneously transmitted. The roaming announcement messages may each be an SMS message. Therefore, according to the present invention, the user of the roaming terminal 130 can easily and accurately confirm the roaming guide message.

An integrated platform (or an integrated business platform) 125 is an open wireless Internet platform capable of providing a wireless Internet infrastructure function in cooperation with the RSCP 200, for example, a KTF Hub for your business (KHUB) (Roaming related service addition subscription information) such as terminal information such as terminal model name information of the roaming terminal 130 and authentication information on whether the roaming terminal subscribes to the supplementary service. The KHUB may be an API (Application Program Interface) hub for providing subscriber authentication and billing services. The unified platform 125 may send the LMS message to the roaming terminal 130 when the roaming information message determined by the RSCP 200 is a long message service (LMS) message.

The roaming terminal 130 is a terminal of a subscriber subscribed to a home network and may have a voice call, a video call, a text message transmission / reception, and a global roaming function as a terminal roaming to a visited network. The roaming terminal 130 may be, for example, a smart phone or a feature phone.

A method of providing a roaming announcement message according to an embodiment of the present invention will be described with reference to FIG.

According to the first location registration processing step S105, the roaming terminal 130 sends its location information to the GLR 115 via communication with the GLR 115 via a mobile communication exchange (MSC) (not shown) Can be registered (stored or transmitted). According to the second location registration processing step (S110), the GLR (115) registers the location information of the roaming terminal (130) in the HLR (105).

According to the registration request step S115, the GLR 115 transmits the location information of the roaming terminal 130 transmitted from the GLR 115 to the RSCP 200 using a customer location registration request message (CS_REG_REQ message) And requests the RSCP 200 to register.

According to the confirmation step and the requesting step S120 and S125, the RSCP 200 confirms whether the location information of the roaming terminal 130, which is the customer, is first registered to the RSCP 200, 130), and terminal information such as terminal model information (terminal model name information). According to the response step S130, the unified platform 125 transmits supplementary service subscription information (information on subscription service subscription information) and terminal model name information of the roaming terminal 130 to the RSCP 200 in response to the request of the RSCP 200 200).

The confirmation step and the requesting step (S120 and S125) and the response step (S130) will be described in detail as follows. When the location registration of the roaming terminal 130 is performed for the first time, the RSCP 200 interworks with the integration platform 125 to transmit the type information (terminal model name information of the roaming terminal 130) of the roaming terminal 130, And stores it in the subscriber DB of the RSCP 200. In addition, the RSCP 200 performs a specific subscription subscription authentication process with respect to the roaming terminal 130, which is a subscriber terminal, in cooperation with the integration platform 125.

According to the SMS confirmation step S135, the RSCP 200 transmits to the roaming terminal 130 based on the supplementary service subscription information (information on whether to subscribe to the supplementary service) and the terminal model name information transmitted in the response step S130 And confirms whether the roaming information message is a short message service (SMS) method. For example, an SMS message may contain less than 90 bytes (short) of text (characters). If it is determined in the SMS checking step S135 that the SMS message is not the SMS message, the method of providing the roaming message message of the present invention proceeds to the LMS checking step S170. If it is confirmed in the SMS checking step S135 that the SMS method is used, the method of providing the roaming guidance message of the present invention proceeds to the transmission delay setting step S140.

The SMS confirmation step S135 will be described in more detail. The RSCP 200 transmits an SMS roaming guidance message customized for each customer corresponding to the additional service, terminal model, and roaming country (visiting country) condition of the roaming terminal 130 May be retrieved from the storage unit of the RSCP 200 to determine the type of the roaming announcement message. The visiting country information may be generated (extracted) from the location information of the roaming terminal 130 by the RSCP 200.

According to the transmission delay setting step S140, the RSCP 200 delays the transmission of the SMS roaming guidance message retrieved in the SMS confirmation step S135, and adjusts the transmission timing of the roaming guide message.

According to the request step and the response step (S145 and S150), the RSCP 200 transmits an SMS roaming guide message to the SMSC 110 using a character transmission request message (Submit SM) defined in the SMCI standard, To the roaming terminal 130. The SMSC 110 transmits an acknowledgment message (Ack) to the RSCP 200 in response to the transmission request of the RSCP 200. The SMSC 110 transmits an acknowledgment message (Ack)

According to the SMS roaming guidance message delivery step S155, the SMSC 110 transmits a reception acknowledgment message (Ack) in the request step and the response step (S145 and S150) And transmits (delivers) the roaming guide message (short message roaming information message) to the roaming terminal 130.

According to the status report step and the confirmation step S160 and S165, the SMSC 110 delivers the SMS roaming guidance message in the roaming guide message delivery step S155, and then transmits the SMS roaming guidance message to the RSCP 200 using the status report message (StatusReport) Reports the completion of transmission of the roaming announcement message, and the RSCP 200 transmits an acknowledgment message (Ack) to the SMSC 110. The RSCP 200 may receive StatusReport, which is a transmission result message defined in the SMCI standard received in the status reporting step S160, and manage the status of message transmission per subscriber, which is a user of the roaming terminal 130. [

The RSCP 200 stores the completion of the transmission of the roaming announcement message to the subscriber DB of the RSCP 200 based on the received status report message (StatusReport), for example, after transmitting the SMS roaming announcement message , And prevents the duplicate transmission of the SMS roaming guidance message when the location registration of the roaming terminal 130 is later performed from the same country and business operator (that is, a communication company (or mobile communication company) in the same country). That is, the RSCP 200 stores the transmission completion of the roaming guide message as described above in order to prevent the sending of the ping-pong message, and therefore, for example, the A national carrier-B national carrier- It is possible to prevent duplicate transmission of the location of the roaming terminal 130 in the foreign country related to the A national operator-B country carrier-C country carrier-A country carrier case.

Even if the SMSC 110 transmits a customized roaming guide message (SMS roaming guide message) to the roaming terminal 130 by a request (a request message) from the RSCP 200, the RSCP 200 may be a communication company of another country, When the location registration of the roaming terminal 130 occurs through another provider (another company in the same country), the SMSC 110 is controlled to transmit a customized roaming guidance message (SMS roaming guidance message) can do.

According to the LMS confirmation step S170, the RSCP 200 determines whether the roaming information message to be delivered to the roaming terminal 130 is a long message service (LMS) scheme. For example, an LMS message may include a long text (character) that exceeds 90 bytes (bytes) and is less than 2000 bytes (bytes). If it is determined that the LMS scheme is not used in the LMS confirmation step (S170), the method of providing the roaming guide message of the present invention ends. When it is confirmed (determined) that the LMS scheme is used in the LMS confirmation step (S170), the roaming guide message providing method of the present invention proceeds to the transmission delay setting step (S175).

The RSCP 200 transmits the LMS roaming information message customized for each customer corresponding to the additional service, terminal model, and roaming country (visiting country) condition of the roaming terminal 130, May be retrieved from the storage unit of the RSCP 200 to determine the type of the roaming announcement message. The visiting country information may be generated from the location information of the roaming terminal 130.

According to the transmission delay setting step S175, the RSCP 200 delays the transmission of the LMS roaming information message retrieved in the LMS checking step S170, and adjusts the transmission time point of the roaming information message.

According to the request step and the response step (S180 and S185), the RSCP 200 transmits an LMS message forwarding preparation report message (MESG_SENDMMSRPT) to the roaming terminal 130 in order to deliver the LMS roaming guidance message confirmed in the LMS checking step S170 The integrated platform 125 sends an LMS roaming announcement message to the unified platform 125 to request the unified platform 125 to deliver an LMS roaming announcement message to the roaming terminal 130, And transmits an acknowledgment response message (Ack) to the RSCP 200 for the transmission request. The RSCP 200 can receive a response message (Ack) that can be defined in the SMCI standard received in the request step and the response step (S180 and S185) and manage the message transmission state of each subscriber of the roaming terminal 130 .

According to the LMS roaming information message delivery step (S190), after the response message (Ack) is transmitted in the request step and the response step (S180 and S185), the unification platform 125 roams the LMS roaming information message And transmits (delivers) the data to the terminal 130.

After the LMS roaming information message is transmitted, the RSCP 200 stores the completion of the transmission of the roaming announcement message to the subscriber DB of the RSCP 200 using the received response message (Ack), for example, That is, when the location registration of the roaming terminal 130 is performed from a communication company (or mobile communication company) in the same country, the LMS roaming information message is prevented from being duplicated. That is, the RSCP 200 stores the transmission completion of the roaming guide message as described above in order to prevent the sending of the ping-pong message, and therefore, for example, the A national carrier-B national carrier- A national carrier-B country carrier-C country carrier-A It is possible to prevent duplicate transmission of the location of a state carrier case.

Even if the integration platform 125 transmits a customized roaming guidance message (LMS roaming guidance message) according to the request (request message) of the RSCP 200, the RSCP 200 can notify the communication company of another country, When the location registration of the roaming terminal 130 is performed through the other company (e.g., another service provider), the integrated platform 125 may be controlled to transmit a customized roaming guidance message (LMS roaming information message)

That is, if the location information of the roaming terminal 130 is registered in the RSCP 200 through the GLR 115 after the location registration of the roaming terminal 130 is performed in the visited network of the A national company, It may not refer to the stored transmission completion information and transmit the roaming information message to the roaming terminal 130 again.

The control unit 220 performs a function of a central processing unit (CPU) and performs a general operation of the components (the communication unit 205, the subscriber database 210, and the storage unit 215) included in the RSCP 200 .

The control unit 220 controls the communication unit 205 to store (register) the location information of the roaming terminal 130 received in the subscriber database 210 and the communication unit 205 to store the location information of the roaming terminal 130 ) From the unified platform (125), and controls the subscriber database (210) to store the terminal model name information and the supplementary service subscription information of the received roaming terminal, and the subscriber database The storage unit 215 searches the storage unit 215 for a roaming guide message corresponding to the terminal model name information and the supplementary service subscription information of the roaming terminal 130 and transmits the roaming guide message to the roaming terminal 130 After the determined roaming information message is transmitted to the roaming terminal 130, the subscriber database 210 transmits the roaming information message to the roaming- . The control unit 220 provides the roaming guide message and the other roaming guide message (the roaming information message about the roaming rate of the visiting country and the roaming call center stored in the storage unit 125, or the guidance of the embassy and the consulate (Sending time) of the roaming information message to be routed to the roaming terminal 130 so that the message is not transmitted (sent) at the same time.

When the determined roaming guidance message is a long message service (LMS) message, the control unit 220 transmits the LMS message to the communication unit 205 so that the integration platform 125 delivers the LMS message to the roaming terminal 130 To the integration platform 125 via the Internet. When the determined roaming information message is a short message service (SMS) message, the controller 220 controls the SMSC 110 to transmit the SMS message to the roaming terminal 130, And transmits the message to the SMSC 110 via the communication unit 205.

In another embodiment of the present invention, the control unit 220 transmits the roaming information message about the roaming rate of the visiting country and the roaming call center stored in the storage unit 215, or the embassy and consulate guidance providing message (Dispatching time) to be provided to the SMSC 110 through the communication unit 205. Since the SMSC 110 sequentially transmits the roaming information messages to the roaming terminal 130 at intervals of time according to the transmission timing, the roaming guiding messages may not be simultaneously transmitted. The roaming announcement messages may each be an SMS message. Therefore, according to the present invention, the user of the roaming terminal 130 can easily and accurately confirm the roaming guide message.
