Abstract

A system for differentially collecting the fee of SMS(Short Message Service) origination when using a global roaming service are provided to charge a user for SMS transmission differentially by country when using a global roaming service by using a mobile communication terminal. A GLR(210) analyzes the position information of an originating terminal, which transmits an SMS message, when receiving a global roaming SMS message from an MSC(216). In addition, the GLR includes MSCID, which has the position information of the originating terminal, to an SMDPP message and transmits the SMDPP message. An SMC(212) transmits the received SMDPP message to a receiving terminal through the MSC at which a domestic receiving terminal(200) is placed, generates the charge data depending on the transmission of the SMS message, and transmits the generated charge data to a billing center(214) with the MSCID parameter. The billing center analyzes the MSCID from the SMS transmission charge data, recognizes the originating country of the SMS message, and processes the fee for the SMS transmission service by country differentially.

The present invention relates to an international roaming method of a mobile communication terminal, and more particularly, to international roaming using a mobile communication terminal in a mobile communication network such as code division multiplex access (CDMA), global system for mobile communication (GSM), and WCDMA. The present invention relates to a system and method for differentially charging a country's short message service (SMS) origination charge.

In general, an international roaming service means that a mobile communication terminal subscriber can continue to receive a mobile communication service such as voice call or SMS using a mobile communication terminal identical to his or her own phone number in another country.

Recently, the standard of living of the people has improved, and the demand for globalization is actively progressed so that the number of overseas departures is increasing rapidly. Accordingly, the demand for international roaming service that provides mobile communication services in other countries is rapidly increasing. There is a trend.

1 is a view illustrating an operation of performing an SMS service among international roaming services using a mobile communication terminal in a CDMA mobile communication network among conventional mobile communication networks such as CDMA, GSM, and WCDMA. Hereinafter, an international roaming SMS service operation will be described with reference to FIG. Will be briefly described. At this time, in the above description of the operation of the international roaming SMS service, it will be described on the assumption that China is an international roaming country for convenience of description.

First, when the mobile terminal subscriber A (100) roaming internationally in China transmits an SMS message to the domestic mobile terminal subscriber B (110), the mobile terminal in China receives an SMS transmission request from the terminal of the subscriber A (100). The mobile network switching center (MSC) 102 transmits an SMSPP (SMS Delivery Pointto Point) ANSI41 message to a gateway location register (GLR) 104 of a domestic mobile communication network associated with the international roaming (S10).

In this SMDPP message, parameters such as SMS_DA (Destination Address, Sender MIN), SMS_ODA (Original Destination Address, Caller ID), SMS_OOA (Original Origination Address, Sender MDN), MIN (Caller MIN), SMS_BearerData (SMS contents), etc. Is included, but the subscriber's location information is not included in the SMDPP message.

Then, the GLR 104 of the domestic mobile communication network transmits the SMDPP message transmitted from the mobile communication network MSC 102 in China to the Short Message Center (SMC) 106 in the mobile communication network (S12), and the SMC 106 is above. The SMDPP message is transmitted to the MSC 108 where the domestic mobile communication terminal subscriber B 110 is located (S14), so that the SMS message is delivered from the MSC 108 to the domestic receiving subscriber B 110.

At this time, when the SMS message via international roaming is successfully delivered to the called party B (110), the SMC 106 generates the billing data so that billing for SMS transmission is performed.

On the other hand, after the SMS message through the international roaming is successfully received by the domestic destination subscriber B (110) as described above, the MSC (108) transmits the SMDPPack message indicating the SMS successful call to the SMC 106 (S16) The SMC 106 transmits it back to the GLR 104 (S18), so that the SMDPPack message is transmitted to the Chinese MSC 102, which has transmitted the SMS message through the GLR 104 (S20).

However, in the conventional international roaming SMS service method as described with reference to FIG. 1, the location information of the subscriber who sent the SMS message is not included in the SMDPP message. There is a problem that can not be distinguished, and thus can not perform differential charging according to the SMS transmission location.

Accordingly, an object of the present invention is to solve the problem that the billing for international roaming SMS could not be differentially applied by charging a single fee regardless of country in the conventional SMS service through international roaming, CDMA, GSM, In the international roaming using mobile communication terminal in mobile communication network such as WCDMA, the international SMS service charge is differentially charged, thereby improving the quality of international roaming service and inducing the active use of international roaming service. The present invention provides a system and method for differentially charging roaming SMS calls.

The present invention for achieving the above object is an SMS charging fee differential charging system when roaming internationally, after receiving an international roaming SMS from any foreign exchange that is roaming internationally, after analyzing the location information of the originating terminal sending the SMS, SMDPP message The GLR transmits the MSCID parameter including the MSCID parameter having the location information of the calling party, and transmits the SMDPP message received from the GLR to the called terminal through the exchange located in the domestic called terminal, and generates the charging data according to the SMS transmission. Afterwards, the MSCID is transmitted to the charging center together with the MSCID parameter, and the MSCID is analyzed in the SMS outgoing billing data transmitted from the SMC, and then the SMS originating country is identified. Characterized in that it comprises a charging center for the differential charging process.

In another aspect, the present invention provides a method for differentially charging the SMS outgoing charges for international roaming, the method comprising the steps of: (a) receiving SMDPP messages in accordance with the international roaming SMS from the GLR from any foreign exchange that is roaming internationally, and (b) Analyzing, by the GLR, location information of the calling terminal, including the MSCID parameter having the location information in the SMDPP message, and transmitting the same to the SMC; and (c) sending the SMDPP message to the domestic called terminal at the SMC. After generating the billing data according to the SMS transmission, and transmitting to the billing center with the MSCID parameter, (d) after analyzing the MSCID in the billing data in the billing center to identify the originating country of the SMS; In accordance with the country-specific differential SMS transmission rate, characterized in that it comprises the step of performing the differential charging process.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the preferred embodiment according to the present invention.

2 is a diagram illustrating a mobile communication network structure for SMS transmission through international roaming according to an embodiment of the present invention. Among the mobile communication networks such as CDMA, GSM, and WCDMA, a mobile communication network structure for CDMA international roaming reception is provided for convenience of description. It is shown. Therefore, the SMS transmission operation method through international roaming in the CDMA network described below will be described in detail, but this is only for convenience of description and may be equally applied to other mobile communication networks such as GSM and WCDMA.

Referring to FIG. 2 above, a mobile station (MS) (B) 200 of a called party's domestic subscriber B is a user interface device, and a call with a calling party terminal formed as a call by the MSC 206. When receiving an SMS message from the mobile terminal (A) 218 of the calling party international roaming subscriber A through international roaming according to the present invention, receives the SMS message sent through the international roaming through the roaming signal network do.

A base transceiver station (BTS) 202 is a device configured as a radio transceiver and transmits / receives voice calls and packet data through a wireless link with a mobile communication terminal 200 in a radio access network (RAN). . A base station controller (BSC) 204 manages a plurality of BTSs 202 and is in charge of processing of radio channel setup, frequency hopping, handover, and the like.

The MSC 206 is responsible for mobility management, location registration / management, authentication, handover, and roaming of the mobile communication terminal (B) 200 of the called party's domestic subscriber B. Also, the MSC 206 is configured through a VLR (Visitor Location Register). Update and store location registration information of mobile communication terminals in the base station, and transmit the changed location registration information of the terminals to the HLR 208 that manages the location registration information of the terminal so that the location information of the mobile communication terminal 200 is periodically updated. do.

In addition, in the SMS message transmission through international roaming according to an embodiment of the present invention, the MSC 206 is an international roaming SMS message through the GLR 210 when an SMS message is sent from the Chinese MSC 216 through international roaming. After receiving the signal, and transmits it to the mobile communication terminal 200 of the domestic mobile communication subscriber B requested.

When the SMC 212 receives an SMS message sent through international roaming from the GLR 210, the SMC 212 delivers the SMS message to the MSC 204 where the called party B's mobile communication terminal 200 is located and forwards it to the called party B. If the SMS is successfully delivered, the billing data is generated. At this time, the SMC 212 is a roaming indicator that indicates whether the MSCID parameter having the location information of the terminal 218 of the subscriber A that sent the SMS message from the GLR 210 and whether the SMS message is generated in Korea or abroad. Roaming Indicator) is transmitted to the charging center 214 together with the charging data.

The billing center 214 analyzes the MSCID when analyzing the billing data transmitted from the SMC 212 to check which country the SMS originated from, and the roaming indicator analysis identifies whether the network is originated through international roaming or international roaming. The country-specific SMS sending rate should be reflected when generating subscriber billing data. In this case, for countries that frequently use international roaming by country, SMS rates may be differentially applied to induce active international roaming services of mobile communication terminal users. That is, for example, each country is ranked according to the international roaming application frequency according to the frequency of the international roaming application frequency, and then the differential charge is set so that the SMS sending rate is set to be relatively low in the order of the highest country. In this way, the service satisfaction of the international roaming subscriber is further increased to induce more international roaming services.

The GLR 210 recognizes that the calling party A 218 is roaming internationally, for example, in China through the MSCID of the corresponding country received at the location registration in the calling party A's location registration step. In this case, the MSCID means an exchange identification number (ID) of the country in which the calling party A 218 is located. That is, after analyzing the location information of subscriber A, which is already stored when receiving SMDPP of subscriber A 218, a new parameter called roaming indicator is added to SMDPP message to distinguish SMSC from roaming and SMSCID from SMDPP. To the SMC 212.

The roaming signal network 215 generally refers to a signal network (STP) for interworking a mobile communication service between an operator and an operator, and includes a signal network provider (Syniverse, Verisign, etc.) providing an STP service.

3 is a flowchart illustrating an operation control flow of differentially charging an SMS service fee for each country through location information of an SMS message originating subscriber during SMS service through international roaming according to an embodiment of the present invention. Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 2 and 3. In particular, in the description of the embodiment of the present invention, the description is made by setting the international roaming target country to China, but it is applicable to any country where international roaming is possible.

First, when the mobile terminal subscriber A 218 who roams internationally in China transmits an SMS message to the domestic mobile communication terminal subscriber B 200, the mobile communication network MSC in China that receives the SMS transmission request from the subscriber A 218. 216 transmits an SMSPP (SMS Delivery Pointto Point) ANSI41 message to the GLR 210 of the domestic mobile communication network associated with the international roaming (S30).

In this SMDPP message, parameters such as SMS_DA (Destination Address, Sender MIN), SMS_ODA (Original Destination Address, Caller ID), SMS_OOA (Original Origination Address, Sender MDN), MIN (Caller MIN), SMS_BearerData (SMS contents), etc. Is included, but the location information of subscriber A is not included in the SMDPP message.

As described above, the SMDPP message transmitted from the Chinese MSC 216 is transmitted to the SMC 212 through the GLR 210. In the GLR 210, at the location registration step for the calling party A 218 according to the present invention. Using the MSCID information from the Chinese MSC 216 received at the location registration, the calling party A 218 is aware that it is roaming in China.

Accordingly, the GLR 210 is a roaming indicator to distinguish between a new parameter called MSCID and an SMS when roaming in the SMDPP message after analyzing the location information of the subscriber A that was already stored when receiving SMDPP from the corresponding calling party A 218. The new parameter is included in the SMDPP message and transmitted to the SMC 212 (S32).

Then, the SMC 212 transmits the above SMDPP message to the MSC 206 where the domestic mobile communication terminal B 200 is located (S34), and the SMS message is delivered from the MSC 206 to the called party B 200. Be sure to

At this time, when the SMS message via international roaming is successfully delivered to the called party B (200), the SMC 212 generates the billing data so that the billing for SMS transmission is performed, the SMC (212) billing center (214) The charging center 214 transmits the MSCID including the location information of the calling party A 218 received from the GLR 210 and the roaming indicator parameter in the charging data when the charging data is generated (S35). It is possible to identify the country from which the SMS was sent.

Accordingly, the billing center 214 analyzes the MSCID when analyzing the billing data of the SMC, checks which country the SMS is originating from, and analyzes the roaming indicator to determine whether the network is originated from overseas or roaming. The country SMS sending fee is reflected when generating subscriber billing data. In this case, as described above, SMS rates may be differentially applied to countries which frequently use international roaming by country to induce active international roaming services of mobile terminal users.

On the other hand, after the SMS message through the international roaming is successfully received by the domestic recipient subscriber B (200) as described above, the MSC (206) transmits the SMDPPack message informing the SMS successful call to the SMC 212 (S36), The SMC 212 transmits this to the GLR 210 again (S38), so that the SMDPPack message is transmitted to the Chinese MSC 216, which has transmitted the SMS message through the GLR 210 (S40).

As described above, in the present invention, unlike the conventional method of imposing an SMS fee as a single fee when transmitting an SMS using international roaming in a mobile communication network, the country in which the calling party which has sent the SMS through international roaming is located is identified. In countries where international roaming is frequently used, SMS charges are differentially charged for each country in a manner of lowering SMS rates, thereby improving the quality of international roaming services and inducing active use of international roaming services.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the invention should be defined by the claims rather than by the described embodiments.

As described above, in the present invention, unlike the conventional method of imposing an SMS fee as a single fee when the SMS is transmitted using international roaming in a mobile communication network, the country in which the calling party which has sent the SMS through international roaming is located is located. In countries where international roaming is frequently used, SMS rates are lowered by country in a way that lowers SMS rates, thereby improving the quality of international roaming services and inducing active use of international roaming services. There is an advantage.
