Description

METHOD AND APPARATUS FOR PROVIDING FOREIGN COUNTRIES ARRIVAL NOTIFICATION SERVICE}

The present invention relates to an overseas roaming service, and more particularly, to a method and apparatus for providing an overseas arrival notification service for notifying a specified customer of an overseas arrival of an overseas roaming subscriber.

With the development of mobile communication technology, mobile communication subscribers can be provided with mobile communication service in the same way as in home network by bilateral agreement and system interworking between mobile operators when visiting overseas. In particular, recently, 3G communication service has been started, and as the user's terminal can be used as it is abroad without renting or changing the terminal, the use of overseas roaming service is increasing.

On the other hand, roaming subscribers who visit overseas usually attempt to make international calls to inform acquaintances of their arrival upon arrival. International call rates have become much cheaper in recent years, but they are still expensive. In addition, when roaming subscribers do not call their acquaintances to inform their overseas arrivals, acquaintances attempt to make international calls directly to roaming subscribers. In Korea, only the caller pays for the call between subscribers, but in some countries, both the caller and the receiver pay for the call, so roaming subscribers who roam to these countries pay international calls when they make calls from subscribers in the home network. do.

In addition, international calls may incur charges for international calls even in a call waiting state before a telephone call is connected. Therefore, when the subscriber of the home network who does not know the roaming facts of the overseas roaming subscriber attempts to make a phone call to the overseas roaming subscriber, there is a case where the international telephone fee is unnecessarily charged. If you know that you've arrived overseas, you can communicate using cheaper text messages than voice calls, but if you don't know you've arrived overseas, you'll need to make an expensive voice call.

Therefore, when an overseas roaming subscriber arrives abroad, a method of notifying unnecessary acquaintances of overseas arrivals to acquaintances of the overseas roaming subscriber is required.

The present invention has been proposed to solve the above problems, and provides a method and apparatus for providing an overseas arrival notification service for notifying an acquaintance of an overseas arrival to acquaintances designated by the overseas roaming subscriber when the overseas roaming subscriber arrives overseas. Its purpose is to.

In addition, the present invention increases the customer satisfaction by informing the acquaintances of the safety of the overseas roaming subscribers by real-time notification to the designated acquaintances in real time whenever the overseas roaming subscribers move to the country.

The foregoing and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings, in which: There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view schematically showing the configuration of a roaming system for providing overseas arrival notification service according to an embodiment of the present invention.

Referring to FIG. 1, the roaming system according to the present embodiment includes a home network 110 and a visited network 130, and subscribers of the home network 110 roam to the visited network 130 to provide a communication service. Receive. The visit network 130 is an overseas network.

In FIG. 1, the mobile terminal 131 is a communication terminal having a voice call, a video call, a text message transmission, and a global roaming function. In this embodiment, the mobile terminal 131 is a terminal roaming to the visited network 130 as a terminal of a subscriber to the home network 110.

Referring to FIG. 1, the home network 110 uses a gateway location register (GLR) 111, a home location register (HLR) 113, and a roaming SCP (Service Control Point) 115. Include. A wireless access network (access network, base station, base station controller, etc.), an exchange (MSC), a message center, etc. are included together, but a description thereof will be omitted here.

The gateway location register 111 serves as a gateway for location registration processing of the mobile terminal 131 roaming from the home network 110 to the visited network 130, and requests a location registration from the roaming mobile terminal 131. When the request is received, the location registration request is transmitted to the home location register 113 and the roaming SCP 115 that accommodate the roaming mobile terminal 131.

The gateway location register 111 downloads the subscriber profile from the home location register 113 and transmits it to the exchange 133 and roaming SCP 115 on the roaming mobile terminal 131 side. In addition, the gateway location register 111 relays the exchange of routing information between the home location register 113 of the home network 110 and the exchange of the visited network 130 or between the home location register of the visited network and the exchange of the home network.

The home location register 113 manages the profile of the mobile subscriber as well as the current location information of the mobile terminal. The home location register 113 stores the location information of the roaming mobile terminal 133 when a location registration request from the roaming mobile terminal 131 comes up through the gateway location register 111 and stores a subscriber profile in the gateway location register 111. Down. The subscriber profile includes intelligent network service trigger information (Global Title (GT), etc. of roaming SCP 115).

The home location register 113 serves to provide routing information for the mobile terminal using the stored location information and the subscriber profile of the mobile terminal. That is, when the routing information request for a specific mobile terminal is received from the originating exchange, the home location register 113 checks the destination exchange using the location information of the mobile terminal, and obtains the routing number from the destination exchange. Transmit to originating exchange.

Roaming SCP 115 provides intelligent network services for roaming subscribers roaming from home network 110 to visited network 130. For example, intelligent network services such as local discount service and prepaid service are controlled. The roaming SCP 115 receives a location registration request from the gateway location register 111 when the roaming mobile terminal 131 registers a location, and also receives a subscriber profile of the roaming subscriber from the gateway location register 111. do. The roaming SCP 115 provides the intelligent network service in association with the exchange 133 of the visited network 130 based on the intelligent network service trigger information included in the received subscriber profile.

In the present invention, when the roaming SCP 115 receives a location registration request from the gateway location register 111 as described above in addition to the intelligent network service, the roaming SCP 115 checks whether the received location registration request is the first overseas location registration, and the first overseas location. In the case of registration, the visited country is analyzed using the identification information of the foreign exchange 133 included in the location registration request.

The roaming SCP 115 has a database that matches foreign exchange identification and country information. The foreign exchange identification information is composed of 'country code + network code (business code) + region code', and detailed country information about the 'country code', 'network code' and 'region code' is stored in a database. The roaming SCP 115 extracts the foreign exchange identification information from the location registration request received from the gateway location register 111, and checks the 'country information' corresponding to the extracted foreign exchange identification information from the information stored in the database. Analyze visited countries of roaming subscribers. The 'country information' may be a region name (eg, Hawaii, Guam, etc.) of a special region other than the pure country name.

Although it is possible to confirm the visited country by using 'country code' among the foreign exchange identification information, the specificity is reduced. For example, there are some places where it is better to advertise the name of a region rather than a country, such as Hawaii, but it is difficult to identify Hawaii information only by country code, and you need to comprehensively check the network code and area code. . In addition, there may be 'adjuncts' that do not belong to the administrative area of a specific country, such as 'Guam', and such 'adjuncts' cannot be identified with 'country codes' alone, and 'network codes' and 'region codes' It should be checked comprehensively. More specifically, if the country code of Guam and Hawaii is the United States and the network code, that is, the carrier is the same, it is necessary to check the area code as well.

In addition, the roaming SCP 115 confirms the information of the subscribers to receive the arrival notification message set by the overseas roaming subscriber, and transmits the arrival notification message notifying the overseas arrival of the overseas roaming subscriber only to the designated subscribers. The roaming SCP 115 checks the subscriber's information to receive the arrival notification message in conjunction with the customer information system (eg, KT's WISE system). Preferably, when roaming SCP 115 receives a location registration request from the gateway location register 111, it checks whether the location registration request is the first overseas location registration, and analyzes the visited country only when the first overseas location registration is the first. Send a message to the designated subscribers. In addition, the roaming SCP 115 may send an arrival notification message to the designated subscribers whenever the location registration country is changed, as well as when initial location registration is attempted overseas.

When the exchange 133 of the visited network 130 receives a location registration request from the roaming mobile terminal 131 roaming into the visited network 130, the switch 133 transmits the received location registration request to the gateway location register 111 of the home network 110. When the outgoing call is received from the roaming mobile terminal 131, before the incoming call is handled (for example, a call processing through an international telephone network), a service request message is transmitted to the roaming SCP 115 to perform intelligent network service processing for the roaming subscriber. request.

Hereinafter, a method of providing an overseas arrival notification service in the roaming system of FIG. 1 will be described with reference to FIG. 2.

2 is a signal flow diagram illustrating a method for providing overseas arrival notification service according to an embodiment of the present invention.

Referring to FIG. 2, the roaming mobile terminal 131 roaming from the home network 110 to the visited network 130 when the location registration requirement such as power-on occurs, the switch 133 of the visited network 130 through the wireless access network. In step S201, the switch 133 of the visited network 130 that receives the location registration request receives a subscriber to the home network 110 based on the identification number of the roaming mobile terminal 133. After confirming that the location registration request (Location Registration Request) to the gateway location register 111 of the home network 110 (S203).

The gateway location register 111 that receives the location registration request from the exchange 133 of the visited network 130 transmits the location registration request to the roaming SCP 115 (S205). The roaming SCP 115 that receives the location registration request extracts the foreign exchange identification information included in the location registration request and uses the extracted overseas exchange identification information to identify the country where the roaming mobile terminal 131 is located ( S207).

Specifically, the roaming SCP 115 has a database in which the foreign exchange identification information and the country information are matched, and extracts the foreign exchange identification information from the location registration request received from the gateway location register 111, and extracts the overseas 'Country information' corresponding to the exchange identification information is checked in the information stored in the database to analyze the visited country of the overseas roaming subscriber. The 'country information' may be a region name (eg, Hawaii, Guam, etc.) of a special region other than the pure country name.

The roaming SCP 115, which has confirmed the country in which the roaming mobile terminal 131 is located as described above, checks whether the roaming mobile terminal 131 has registered the initial location overseas or moved the country after the initial location registration overseas. In the case of location registration or country movement, the information of the subscribers who will receive the arrival notification message registered by the roaming subscriber is checked and the arrival notification message is transmitted to the corresponding subscribers (S209). In addition, the roaming SCP 115 transmits to the roaming mobile terminal 131 an arrival notification service confirmation message indicating that the arrival notification message has been transmitted to the designated subscriber (S211).

Here, the arrival notification message basically includes the phone number of the roaming mobile terminal 131, the arrival time (based on the home network), and arrival country information. For example, the arrival notification message is "[Arrival Notification] [2021] You arrived in Japan on December 21 at 12:30". And the example of the arrival notification service confirmation message is, "[notification notification] the arrival notification text has been sent to two people registered by the customer".

Meanwhile, the gateway location register 111 that receives the location registration request from the exchange 133 of the visited network 130 transmits the location registration request to the home location register 113 that accommodates the roaming mobile terminal 131 (S2013). ). Then, the home location register 113 updates the location information of the roaming mobile terminal 131, inquires the subscriber profile of the roaming subscriber, and transmits it to the gateway location register 111 by inserting it in an Insert Subscriber Data (ISD) message ( S215). Upon receiving the ISD message including the subscriber profile, the gateway location register 111 transmits the received ISD message to the exchange 133 on the roaming mobile terminal 131 side (S217). The exchange 133 of the visited network 130 registers and stores the subscriber profile included in the ISD in the visited location register.

In addition, the gateway location register 111 registers the roaming subscriber's profile with the visited network 130 and simultaneously inserts the roaming subscriber's profile into the roaming SCP 115 that provides the intelligent network service to the roaming subscriber. Subscriber Data) is sent to the message (S219). The roaming SCP 115 registers the roaming subscriber's profile and then provides the intelligent network service to the roaming subscriber.

As described with reference to FIG. 2, when an overseas roaming subscriber moves to an overseas visited network and powers on the roaming mobile terminal 131 for the first time, the roaming SCP 115 of the home network 110 roams. The foreign exchange roaming subscriber checks the country to which the roaming subscriber has moved by using the foreign exchange identification information included in the location registration request received from the mobile terminal 131 and notifies the designated customer. In addition, the roaming SCP 115 identifies the foreign exchange included in the location registration received from the roaming mobile terminal 131 when a new location registration occurs when the roaming mobile terminal 131 moves to a country after the initial location registration from abroad. After confirming the movement of the country with the information, the foreign roaming subscriber will be notified of the move to the new country.

3 is a flowchart illustrating a method for providing an overseas arrival notification service in a roaming SCP according to an embodiment of the present invention.

Referring to FIG. 3, first, a roaming SCP 115 establishes a database of identification information of foreign exchanges (S301). The foreign exchange identification information is composed of 'country code + network code (business code) + region code', and country information is mapped to the 'country code', 'network code' and 'region code' and stored in a database.

After constructing the overseas exchange identification information as a database in this manner, the roaming SCP 115 receives a location registration request from the overseas roaming mobile terminal 131 from the overseas exchange 133 (S303). Location registration occurs for various reasons, such as when the mobile terminal is powered on or when the mobile terminal moves a service area. If the location registration requirement is satisfied, the roaming mobile terminal 131 transmits a location registration request to the exchange 133 of the visited network 130 where it is located, and the exchange 133 of the visited network 130 is the home network 110. The gateway location register 111 transmits a location registration request to the gateway location register 111, and the gateway location register 111 transmits the location registration request to the roaming SCP 115.

The roaming SCP 115 that receives the location registration request from the exchange 133 of the overseas visited network 130 checks whether the location registration is the first overseas location registration (S305). In the case of the first overseas location registration, roaming SCP 115 extracts the foreign exchange identification information from the received location registration request and checks 'country information' corresponding to the extracted foreign exchange identification information in the information stored in the database. In order to analyze the country in which the roaming mobile terminal 131 arrived (S307).

Meanwhile, when the location registration is not the first overseas location registration, the roaming SCP 115 extracts the foreign exchange identification information from the received location registration request and recalls 'country information' corresponding to the extracted foreign exchange identification information. The information stored in the database is analyzed to analyze the country in which the roaming mobile terminal 131 arrives (S313), and the roaming mobile terminal 131 moves the country by comparing the analyzed country information and the country information checked at the previous location registration. Check (S315).

When the roaming mobile terminal 131 registers the first overseas location or moves the country, the roaming SCP 115 checks the information of the subscribers to receive the arrival notification message registered by the roaming subscriber and arrives at the subscribers. The notification message is transmitted (S309). In addition, the roaming SCP 115 transmits an arrival notification service confirmation message indicating that the roaming mobile terminal 131 transmits the arrival notification message to the designated subscriber (S311).

Here, the arrival notification message basically includes the phone number of the roaming mobile terminal 131, the arrival time (based on the home network), and arrival country information. For example, the arrival notification message is "[Arrival Notification] [2021] You arrived in Japan on December 21 at 12:30". And the example of the arrival notification service confirmation message is, "[notification notification] the arrival notification text has been sent to two people registered by the customer".
