Referring to FIG. 1, the prohibited business network information providing system according to an embodiment of the present invention is included in the home network 100, and includes a gateway location register 110, a SIM card management center 130, and a message center 140. Include. At this time, the home network 100 is a business network that provides a mobile communication service such as Wideband Code Division Multiple Access (WCDMA) to a terminal in the home country. In addition, the visited network 70 is an overseas business network that provides in / outbound roaming service from the foreign country to the home network to the terminal 50 of the home network according to a partner contract relationship with a telecommunication company managing the home network. .

The terminal 50 requests overseas outbound roaming that performs outbound roaming service to the home network based on information of a public land mobile network (PLMN) managed by a USIM card. Shall. The terminal 50 may request a location registration to the home network 100 through the visit network 70 for the roaming service. In addition, after the process of performing the location registration update, the terminal 50 includes the prohibited operator information according to the information on the visited network used in the process of the location registration update received from the message center 140 of the home network 100. According to the update message to update the prohibited carrier information in the USIM card, it is possible to perform a roaming service using the updated information of the overseas provider network. At this time, the SIM card can store, as forbidden operator network information, a prohibited operator network having a predetermined number or less (for example, 20) or less.

The gateway location register (GLR) 110 of the home network 100 is configured to relay an overseas roaming service, and stores prohibited service network group information including one or more prohibited service network identification information for each region. Prohibited service network group information may be configured as shown in Table 1 below.

division Ban Business Group North America US A Operators 310150, 310380…
Mexico B operators 340001, 340002… Asia Hong Kong A Operator 45403,…
China B operator 46000,…

When the gateway location register 110 receives the location registration request of the terminal 50 through the visit network 70, the card of the update message request information including the prohibited business network information of the region corresponding to the visit network 70 Send to the management center (130). For example, when the gateway location register 110 receives a location registration request of the terminal 50 through the visiting network 70 (for example, being serviced in the United States), the area to which the visiting network 70 belongs is determined. You can judge North America. In this case, the location registration request may include information for identifying the visited network 70, and the gateway location register 110 may indicate local information corresponding to an area corresponding to the information for identifying the visited network 70. Can be stored in advance. The gateway location register 110 confirms that the business network included in the prohibited business network group corresponding to North America, which is the region to which the visit network 70 belongs, is the business network of the US A and Mexico B businesses. The gateway location register 110 transmits the prohibited business network information including the business network identification information of the US A and Mexican B operators to the SIM card management center 130.

The USIM Management Center (UMC) 130 manages system registration information related to the SIM card provided in the mobile terminal 50, and provides an application for the SIM card related service to be installed in the terminal. In addition, an update message according to the over the air (OTA) protocol may be transmitted to the terminal so that changes in the service policy may be reset. Here, for example, the update of the information stored in the SIM card is made through a short message. However, the present invention is not limited thereto, and the control message for updating the information is SMS (Short Message Service) or LMS (Long Message Service). ), An update message for updating the information of the SIM card may be transmitted through the MMS (Universal Message Service) or the USSD (Unstructured Supplementary Service Data).

Hereinafter, a process of providing the prohibited business network information by the above-described prohibited business network information providing system will be described in detail.

2 is a flowchart illustrating a process of providing forbidden business network information by a forbidden business network information providing system according to an exemplary embodiment of the present invention.

Referring to FIG. 2, in step 210, the terminal 50 transmits a location registration request to the switch 55 of the visited network 70 to request location registration of the terminal 50.

In step 220, the exchange 55 transmits a location registration request of the terminal 50 through the gateway location register 110, and the gateway location register 110 is through a home location register (HLR) 120. Perform location registration. For example, the exchange 55 of the overseas visiting network transmits a location registration update message to the gateway location register 110. The location registration update message may include an International Mobile Subscriber Identity (IMSI) number of the subscriber roaming terminal assigned for roaming and MSC GT (Global Title), which is source identification information. The GLR 115 transmits the location registration update message back to the home location register 120 of the home network, whereby the location registration update is performed between the gateway location register 110 and the home location register 120, and the gateway location register 110 is performed. May receive a subscriber profile from home location register 120. When location registration is completed between the gateway location register 110 and the home location register 120, the GLR 115 may transmit a location registration result such as a subscriber profile to the exchange 55 of the visited network 70. The exchanger 55 of the visited network having received the location registration result as the location registration is completed may respond to the terminal 50 with a completion message of location registration update.

In step 230, the gateway location register 110 transmits the prohibited provider network information corresponding to the region to which the visited network 70 to which the location registration request is transmitted belongs to the SIM card management center 130. In this case, the gateway location register 110 may store in advance the prohibited service network group information including the operator network information for one or more prohibited service networks for each region, and the visited network 70 may refer to the prohibited service network group information. Forbidden operator network information corresponding to a region to be detected may be transmitted to the SIM card management center 130.

In operation 240, the SIM card management center 130 transmits an update message transmission request including the prohibited provider network information to the message center 140.

In operation 250, the message center 140 transmits an update message to the terminal 50 through the visit network 70.

In step 260, the terminal 50 updates the prohibited carrier network information of the USIM according to the update message.

Thereafter, the terminal 50 restricts the location registration to the provider network according to the updated prohibited provider network information.

As described above, since the prohibited provider network information providing system updates the prohibited provider network information stored in the USIM of the terminal 50 according to the location of the operator network currently visited by the terminal 50, It is possible to overcome the limitation of registering a prohibited business network. That is, since the information on the prohibited provider network for the prohibited provider network that wants to restrict the location registration among the service provider networks providing the service in the region where the terminal 50 is located is updated to the SIM card, regardless of the location of the terminal 50. Compared to the method of fixedly storing the prohibited provider network information in the SIM card, the number of the operator networks that can be registered as the prohibited provider network is large. Accordingly, the system for providing a prohibited operator network information according to the present invention increases the number of prohibited carrier networks whose roaming is restricted in accordance with the increasing number of operator networks, and sets the prohibited provider network to a number that can be registered as a prohibited provider network in the SIM card. Even if you wish to do so, without changing the structure of the conventional SIM card or the terminal 50, it is possible to set the prohibited network.

The present invention has been described above with reference to the embodiments thereof. Many embodiments other than the above-described embodiments are within the scope of the claims of the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. The disclosed embodiments should, therefore, be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
