5 is a flowchart illustrating a method of providing a guide message for an inbound roaming terminal according to a third embodiment of the present invention.
In FIG. 5, the exchange 122, the GLR 124, the message center 126 and the gateway 128 of the visited network 120 perform the method of providing a guide message for the inbound roaming terminal according to the third embodiment. However, the present invention is not necessarily limited thereto, and the exchanger 210 corresponding to the switch 122, the location registration manager 220 corresponding to the GLR 124, and the message processor corresponding to the message center 126 are provided. External network interworking unit 240 corresponding to 230 and the gateway 128 may be implemented to perform the function.
When the inbound roaming mobile communication terminal 110 transmits the location registration message to the exchange 122 of the visited network 120 (S510), the exchange 122 transmits the location registration message received from the mobile communication terminal 110 to the GLR. And transmits to 124 (S512).
The GLR 124 checks whether the location registration message received from the exchange 122 is the initial location registration (S520). As a result of checking in step S520, when the location registration message is the first location registration, the GLR 124 checks whether the location registration area is a location registration for another area different from the existing area (S522). When the inbound roaming mobile communication terminal 110 performs location registration, the GLR 124 of the visited network 120 confirms whether the location is the initial location registration and the location registration area. Here, the reason for confirming whether the first location registration is the location registration is raised again, such as when the inbound roaming mobile communication terminal 110 is powered off / power-on. This is to prevent the retransmission of the guide text message if it comes. That is, confirming the location registration area manages the area so that content matching the area can be provided to the inbound roaming mobile terminal 110, and the inbound roaming mobile terminal 110 moves to another area. If you do, it is to retransmit the information for your region. That is, when the GLR 124 of the visitor network 120 transmits the information to the content providing server 142 or directly sends a text, the GLR 124 attempts to register the location in an area different from the initial location registration area and the existing location registration area. .
The GLR 124 transmits a location registration message to the HLR 132 of the home network 130 (S530), receives a location registration success response message (S532), and then sends a location registration success response message to the exchange 122. It transmits (S540). The exchange 122 transmits a location registration success response message to the inbound roaming mobile communication terminal 110 (S542). The GLR 124 of the visited network 120 transmits a location registration message to the HLR 132 of the home network 130 to register the inbound roaming mobile communication terminal 110.
On the other hand, as a result of the check in step S522, when the location registration area is a location registration for a region different from the existing area, the GLR 124 transmits the location registration area information to the gateway 128 (S550), the gateway 128 The location registration area information is transmitted to the content providing server 142 of the external network 140 (S552).
The content providing server 142 of the external network 140 receives a request signal for a guide text message according to at least one of preset national language information and access specification information for each of a service provider, a server, and a message center. 130 to the message center 134 (S554). That is, the content providing server 142 of the external network 140 may set the corresponding national language information for the guide text message to be transmitted to the inbound roaming mobile terminal, and access specification information for each of the service provider, the server, and the message center. At least one of the information is stored.
The message center 134 of the home network 130 transmits a guide text message to the GLR 124 of the visited network 120 according to a request signal received from the content providing server 142 of the external network 140 (S556). ), The GLR 124 transmits the guide text message to the switch 122 (S558), and the switch 122 transmits the guide text message to the mobile communication terminal 110 (S560).
When the mobile terminal 110 receives the guide text message from the switch 122 and then receives a connection command by a user operation, the mobile communication terminal 110 connects to the content providing server at step S562 to receive local tourism information corresponding to the guide text message. Local information content including at least one or more of the roaming fee information, various discount information and discount coupon information is received (S570). That is, when the inbound roaming mobile communication terminal 110 receives a guide text message and receives a connection button by a user's manipulation, the inbound roaming mobile terminal 110 connects to the content providing server 142 of the external network 140 to receive local tourism information, You will receive roaming charges, mobile coupons that can provide various discounts.
In FIG. 5, the visited network 120, the home network 130, and the external network 140 sequentially execute steps S510 to S570, but this is exemplarily described in the technical idea of an embodiment of the present invention. It is merely a person having ordinary skill in the art to which an embodiment of the present invention belongs, the visitor network 120, the home network 130 and the external network 140 within a range without departing from the essential characteristics of an embodiment of the present invention 5 may be variously modified and modified by changing the order described in FIG. 5 or executing one or more steps of steps S510 to S570 in parallel, and therefore, FIG. 5 is not limited to the time series order.
