Description

Roaming service control system and method {ROAMING SERVICE CONTROL SYSTEM AND METHOD}

The present invention relates to a roaming service, and more particularly, when a terminal requests roaming location registration to a network operated by a specific operator, the home network operator of the terminal applies roaming traffic control technology. The present invention relates to a roaming service control system and method for making it difficult for a home network operator of a terminal to apply roaming traffic control technology to the specific operator in the long term.

In general, when a terminal roams in a home network in a plurality of networks operated by different operators, a network of an operator having a place where the terminal owner is located as a service area when roaming occurs in a home network. When moving to an in-roaming local area network, a roaming service is provided in which a roaming area network obtains location information of a terminal moved from a home network and performs a call service for the corresponding terminal based on the obtained information.

In a roaming local area network, when a terminal attempts to register a location with an exchange of a first provider network for roaming service, the location registration is rejected according to the roaming traffic control of the home network operator of the terminal, so the first provider attracts customers who request roaming service. There is a problem that cannot be done.

That is, the roaming revenue of the first provider is reduced by the terminal customers roaming to the first provider network by roaming to another competitor network according to the roaming traffic control of the terminal home network.

However, there is no way for the first operator to know which operator of the home network is controlling roaming traffic.

The present invention proposes a roaming service control system and method for identifying a service provider when a home network operator of a terminal requesting location registration for a roaming service applies a roaming traffic control technique.

In addition, the present invention proposes a roaming service control system and method that enables a home network operator of a terminal requesting location registration for a roaming service to prevent application of roaming traffic control technology to a specific operator.

The roaming service control system according to an exemplary embodiment of the present invention includes a switch that receives and transmits a roaming location registration request message from a terminal, and a home to which the terminal subscribes to a roaming location registration request message transmitted from the exchange. The roaming location registration success message is set to prohibit sending and receiving of the terminal if the operator of the home location register is a non-registered business operator when the operator of the home location register is previously registered. And a relay location register for transmitting to the exchange.

In addition, the relay location register according to an embodiment of the present invention transmits and receives a roaming location registration request message of the terminal from the switch and transmits and receives the roaming location registration request message to the home location register of the home network operator subscribed to the terminal And generating a roaming location registration success message that is set to prohibit receiving and receiving of the terminal if the operator of the home location register is a non-registered operator in advance when the roaming location registration rejection message is received from the home location register. It includes a control unit.

In addition, the roaming service control method of the relay location register according to an embodiment of the present invention comprises the steps of receiving a roaming location registration request message sent by the terminal from the exchange, and the home network operator subscribed to the received roaming location registration message Transmitting a home location register to the home location register; and receiving a roaming location registration rejection message from the home location register; determining whether a business of the home location register is a pre-registered unfriendly business; The non-friendly service provider may include generating a roaming location registration success message set to prohibit incoming and outgoing calls of the terminal and transmitting the message to the exchange.

According to the present invention, when the home network operator of the terminal requesting the location registration for the roaming service applies the roaming traffic control technology, the corresponding operator may be identified.

In addition, the present invention, even if the terminal requests a location registration for roaming service in a network operated by a specific operator, even if the home network operator of the terminal refuses to register the location, the roaming location registration succeeds and does not use roaming-related call reception in the long run It is effective to make it difficult to apply roaming traffic control technology for a specific operator.

On the other hand, various other effects will be disclosed directly or implicitly in the detailed description of the embodiments of the present invention to be described later.

1 is a block diagram illustrating a roaming service control system according to an exemplary embodiment of the present invention, and illustrates a case in which a terminal 100 having a B network as a home network moves to a roaming local network A as an example. .

Referring to FIG. 1, a roaming service control system according to an embodiment of the present invention is a system belonging to a roaming local area network (A), a base station (Node B) 210, a base station controller (RNC: Radio Network Control) 220, A mobile switching center (MSC) 230 and a gateway location register (GLR). Although an embodiment of the present invention has been described as a 3G network, the same may be applied to other generation networks such as 4G. For example, Long Term Evolution (LTE), which is one of 4G, will be described in the LTE network when the terminal 100 transmits a roaming location registration request message to an Evolved Packet Core (EPC) through wireless communication with an eNode B. The registration request message may be transmitted to the relay location register 240.

The terminal 100 transmits a roaming location registration request message to the exchange 230 through wireless communication between the base station 210 and the base station controller 220 in order to receive a roaming service in the roaming local area network A.

The exchange 230 transmits the roaming location registration request message received from the terminal 100 to the relay location register 240.

The relay location register 240 recognizes the home network B of the terminal 100 by interpreting a country code of the terminal 100 through an IMSI (International Mobile Subscriber ID) included in the location registration request message.

The relay location register 240 checks a home location register (HLR) ID where subscriber information of the terminal 100 is stored based on the subscriber number of the terminal 100.

The relay location register 240 transmits a roaming location registration request message to the identified home location register 310 of the home network B.

The relay location register 240 determines whether the roaming location registration rejection message is received from the home location register 310, that is, the operator of the home network (B) company, that is, the home location register 310, is a non-registered business. . In this case, the unfriendly service provider may mean a service provider whose roaming settlement fee is higher than that of other companies.

The relay location register 240 transmits a roaming location registration success message set to prohibit roaming-related reception and reception of the terminal 100 when the operator of the home location register 310 is a pre-registered unfriendly operator, to the exchange 230. In this case, even if the roaming location registration is normal, the terminal 100 cannot receive the roaming call service.

When the number of roaming location registration rejection messages received from the home location register 310 is greater than or equal to a preset reference value, the relay location register 240 may register a provider of the home location register 310 as an unfriendly operator.

In another exemplary embodiment, the relay location register 240 may perform statistical processing on the number of roaming location registration rejection messages transmitted by the home location register 310 operator. Then, the system operator may check a statistical result of the roaming location registration rejection message stored in the relay location register 240 to register a specific home network (B) operator as an unfriendly operator.

The home location register 310 transmits a location registration success or rejection message to the relay location register 240 according to the determination of the home network B operator.

2 is a block diagram of a relay location register included in a roaming service control system according to an exemplary embodiment of the present invention.

The illustrated relay position register includes a controller 241, a transceiver 243, and a memory 245.

The transceiver 243 receives a roaming location registration request message from a terminal to receive roaming service through an exchange, and transmits the received roaming location registration request message to a home location register of a home network operator subscribed to the terminal. .

The control unit 241 controls the overall operation of the relay position register according to an embodiment of the present invention. In addition, the control unit 241 generates a roaming location registration success message set to prohibit sending and receiving of the terminal if the operator of the home location register is a non-registered operator registered in advance when the roaming location registration rejection message is received from the home location register to the exchange. Control to transmit.

Meanwhile, if the number of roaming location registration rejection messages received from the home location register is greater than or equal to a preset reference value, the controller 241 registers the service provider of the home location register, that is, the home network service provider of the terminal requesting the roaming location registration as an unfriendly provider. Can be.

In another embodiment, the controller 241 may provide the operator with statistics on the number of roaming location registration rejection messages transmitted by the home location register to register the measured home network operator as an unfriendly operator.

The memory 245 stores various pieces of information necessary for controlling the operation of the relay location register 240 according to an embodiment of the present invention. Also, the memory 245 may store roaming location registration rejection messages received from home location registers for each home network operator under the control of the controller 241.

3 is a flowchart illustrating an operation process of a roaming service control system according to an exemplary embodiment of the present invention.

1 and 3, the terminal 100 transmits a location registration request message for roaming in the roaming local area network A to the exchange 230 (S110).

The exchange 230 transmits the received location registration request message to the relay location register 240 (S120).

The relay location register 240 checks the home network B of the terminal 100 and the corresponding home location register 310 through the location registration request message, and then transmits a location registration request message to the identified home location register 310. Transmit (S130).

When the location registration request message is received, the home location register 310 confirms whether the business operator that transmitted the location registration request message is a friendly business operator, and transmits a location registration rejection message to the relay location register 240 unless the business operator is a friendly business operator ( S140). On the other hand, the home location register 310 registers the location even if the service provider does not meet the normal location registration requirements even if the operator is a friendly service provider (for example, a subscriber who is not allowed to roam internationally or requests to apply for an international roaming request). A reject message can be sent.

When the location registration rejection message is received from the home location register 310, the relay location register 240 determines whether the operator of the home location register 310 is a pre-registered non-friendly business (S150).

The relay location register 240 transmits a location registration rejection message to the exchange 230 unless the operator is a non-registered unregistered operator as a result of the determination in step S150 (S160). In this case, it can be seen that the location registration request of the subscriber of the terminal 100 does not meet the normal location registration requirements.

The exchange 230 transmits a location registration rejection message received from the relay location register 240 to the terminal 100 (S170).

On the other hand, the relay location register 240 generates a location registration success message set to prohibit roaming-related reception if the operator of the home location register 310 is registered in advance in the step S150 and transmits to the exchange 230. (S180).

The exchange 230 transmits the location registration success message received from the relay location register 240 to the terminal 100 (S190). In this case, even if the roaming location registration is normal, the terminal 100 cannot receive the roaming call service.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof. I can understand that.

Therefore, since the embodiments described above are provided to completely inform the scope of the invention to those skilled in the art, it should be understood that they are exemplary in all respects and not limited. The invention is only defined by the claims.

In the case of the conventional roaming service, even if the first service provider is unable to attract roaming service request terminal customers according to the roaming traffic control of the home network operator of the roaming terminal regardless of the company's intention, roaming revenue may be reduced. Nevertheless, the first service provider has no way of knowing which service provider of the home network is performing roaming traffic control. However, the present invention provides that the home network service provider of the terminal requesting location registration for roaming service may apply roaming traffic control technology. In this case, when the terminal requests the location registration for roaming service in a network operated by a specific operator, the roaming location registration succeeds and the roaming call is received even when the home network provider of the terminal refuses to register the location. In the long run so that This can make it difficult to apply roaming traffic control techniques.
