The present invention relates to a system and method for providing a catch call service for an unreceived call to a mobile terminal subscribed to an international roaming service.

In general, a mobile terminal refers to any electronic device that can move freely within a service area formed by a base station and communicate by wireless call and wireless connection to the other party anytime and anywhere under the control of an exchange. By providing additional services, the service area is gradually expanding.

Among these additional services, the catch call service is a service that can check all of the incoming calls, such as when the mobile terminal is turned off or on a call. can confirm. That is, a user who subscribes to the catch call service can receive the caller's phone number as a text message or the like even if the caller hangs up the phone without leaving the phone number.

Catch call service can be useful when watching a movie or performance as a proper service for students who have many meetings and who can't talk during class.

However, the above-mentioned catch call service provides a text message including the calling number only for callers of a certain time, for example, 48 hours or older, and therefore, when the user uses the international roaming service for a long time overseas business trip or travel, etc. Depending on the constraints, not all callers can be provided.

In addition, depending on the agreement between the domestic mobile communication network and the operators of overseas mobile communication networks, even if the text message service is excluded or such a text message service is available, the communication method of these mobile communication networks, for example, code division multiple access (CDMA) In the case of adopting different communication methods such as Global System for Mobile telecommunication (GSM) and the like, the quality of the text message service may not be guaranteed, and thus the text message by the catch call service may not be smoothly provided.

The present invention is to solve the problems of the prior art, when the mobile terminal subscribed to the international roaming service is incapable of receiving a call originating in the country from abroad, the location registration of the mobile terminal occurs in the domestic By providing information on an unreceived outgoing call to a mobile terminal at a point in time, a system and a method for providing a catch call service to improve user convenience can be provided.

In addition, the present invention provides the mobile terminal with information on the outgoing outgoing call at the time when the location registration of the mobile terminal occurs in the country as a callback message to induce a call connection based on this, thereby increasing sales from the mobile carrier's point of view. It is possible to provide a system and method for providing a catch call service that can be expected.

To this end, the system for providing a catch call service according to an aspect of the present invention determines the starting point of roaming of a mobile terminal roaming from a first mobile communication network to a second mobile communication network and the mobile terminal determines the first mobile communication. A first HLR (Home Location Register) for determining roaming end point when entering the communication network and the mobile terminal generated within the roaming period of the mobile terminal calculated based on the determined roaming start point and the roaming end point. It may include a service server for requesting the message center to send a callback message including the location information is stored for the outgoing call.

In addition, a method for providing a catch call service according to another aspect of the present invention is a mobile roaming from the first mobile communication network to the second mobile communication network by a first HLR (Home Location Register) of the first mobile communication network Determining a roaming start time of the terminal and determining a roaming end point when the mobile terminal enters the first mobile communication network; and calculating a service server based on the roaming start time and the roaming end time determined by the message center; And requesting to send a callback message including location information in which outgoing information on an unreceived call to the mobile terminal generated within a roaming period of the mobile terminal is stored.

Hereinafter, a system and a method for providing a catch call service according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4.

The present invention proposes a new method for providing a catch call service according to an international roaming service. That is, when the mobile terminal subscribed to the international roaming service is incapable of receiving a call originating in Korea from abroad, the call is not received according to the incompetent state at the time of registration of the location of the mobile terminal in Korea. Location information for providing call origination information for the mobile station may be provided as a callback message including a Uniform Resource Location (URL).

1 is an exemplary view showing the configuration of a schematic system according to an embodiment of the present invention.

As shown in FIG. 1, the system according to the present invention includes a first switch 111, a first home location register (HLR) 112, and a first gateway location register in the first mobile communication network 110. 113, the International Roaming Gateway System (IRGS) 114, the message center 115 and the service server 116 and the second GLR 121, the second HLR 122 in the second mobile communication network 120 ) And a second exchanger 123 and the like.

In this case, the first mobile communication network 110 and the second mobile communication network 120 are networks to which different mobile communication methods are applied, for example, a code division multiple access (CDMA) network and a global system for mobile (GSM). Not only does it mean a telecommunication) network, but also a concept of a network operated by different mobile communication operators.

The mobile terminal 100 is a device capable of receiving a mobile communication service, for example, a voice call, a video call, a message transmission, and the like, and may include a mobile phone, a personal digital assistant (PDA), a notebook, and the like.

The mobile terminal 100 in the first mobile communication network 110 may subscribe to an international roaming service in order to receive a mobile communication service in the second mobile communication network 120. This refers to a service that enables a mobile terminal user of a mobile phone to use a mobile phone in the same country as in Korea.

When the mobile terminal 100 subscribing to the international roaming service roams from the first mobile communication network 110 to the second mobile communication network 120, the mobile terminal 100 of the second mobile communication network 120 The location registration of the second HLR 122 may be performed to provide location information of the mobile terminal 100 to the second GLR 121 in real time. Then, the second GLR 121 provides service profile information of the mobile terminal 100, for example, additional service information, etc. from the first HLR 112 through the first GLR 113 of the first mobile communication network 110. It can be received and stored together with the location information of the mobile terminal 100 and managed.

The IRGS 114 may process a call generated in the first mobile communication network 110 and connect it to the mobile terminal 100 roamed into the second mobile communication network 120, where the mobile terminal 100 is incapable of receiving a call. In one case, if outgoing information about an unreceived call is stored, for example, an outgoing time and an outgoing telephone number, and the mobile terminal 100 is subscribed to the catch call service, the outgoing information about the unreceived call may be provided to the service server.

The first HLR 112 provides the service profile information of the mobile terminal to the second HLR 122 and, accordingly, automatically registers an international roaming service to the second mobile communication network 120 for the mobile terminal 100. Can be. That is, when the first HLR 112 confirms that the mobile terminal 100 has completed the location registration with the second HLR 122 from the first GLR 113, the first HLR 112 determines that the roaming service has been started. You can judge. On the contrary, if the first HLR 112 confirms that the mobile terminal 100 enters the first mobile communication network 110 from the second mobile communication network 120 and completes the location registration after the international roaming service is started. Since it is determined that the roaming service has ended, it may be determined whether the roaming of the mobile terminal 100 is terminated.

In this case, the first HLR 112 may inform the service server 116 that the international roaming service of the mobile terminal 100 has ended, and the roaming time is determined based on the roaming start time and the roaming end time of the mobile terminal 100. The calculated roaming time can be provided together.

The service server 116 is a device for providing a catch call service. In particular, the service server 116 is a device for providing a catch call service for an unreceived call generated according to an international roaming service. Such a catch call service may refer to a service that allows a user to check all calls made in an unreceivable state through a text message, such as when the mobile terminal 100 is turned off or on a call.

In this case, the service server 116 may be constructed as a single server to provide a catch call service to all mobile terminals 100 subscribed to the catch call service regardless of whether or not roaming, and not roaming mobile terminals ( A server may be provided separately from a server capable of providing a catch call service for 100), or may be constructed of a plurality of servers to provide a catch call service according to a country or a mobile communication provider.

In addition, the service server 116 may provide a separate web page for inquiring details of outgoing information on an unreceived call to the mobile terminal 100 through the wired or wireless Internet. To this end, the service server 116 may set the storage period of the outgoing information for the unreceived call according to the international roaming service to the period during which the international roaming service is provided.

The message center 115 may receive a request for the transmission of the callback message from the service server 116 and transmit the callback message to the mobile terminal 100 according to the request. The SMSC (Short Message) may be provided to provide a text message, an image, a video, and the like. The concept may include a service center (LMSC), a long message service center (LMSC), a multimedia message service center (MMSC), and the like.

As described above, when the mobile terminal roaming internationally is incapable of receiving a call originating in Korea from abroad, the present invention makes a call for an unreceived call according to the unreceiving status at the time when the location registration of the mobile terminal is completed in Korea. By providing the information to the mobile terminal as a callback message, the user's convenience can be improved.

2 is an exemplary view showing a method for performing location registration in a roaming area according to an embodiment of the present invention.

As shown in FIG. 2, when a mobile terminal roaming from the first mobile communication network to the second mobile communication network is turned on in the second mobile communication network, that is, the roaming area, the mobile terminal is located in the second HLR of the second mobile communication network. In S210, the second HLR may perform location registration of the mobile terminal accordingly (S220).

When the location registration of the roaming mobile terminal is completed, the second HLR provides the location information of the roaming mobile terminal to the second GLR in real time, indicating that the international roaming service is started (S230), and the second GLR of the roaming mobile terminal The location information may be stored and managed (S240). Then, the second GLR may request the service profile information of the mobile terminal from the first HLR through the first GLR (S250).

The first HLR may detect service profile information (S251) and provide it to the second GLR through the first GLR (S252). Accordingly, the first HLR may determine this time point as the roaming start time point of the mobile terminal (S260). The second GLR may store and manage location information of the mobile terminal provided in real time together with service profile information of the mobile terminal (S270).

When the location registration of the roaming mobile terminal is completed and the service profile information of the mobile terminal is provided from the first HLR to the second HLR where the location registration is performed (280), the service profile information is stored in the second HLR (S290). 3) A process of processing outgoing information on an unreceived call generated according to an unreachable state of a mobile terminal can be connected to a roaming mobile terminal from a first mobile communication network.

3 is an exemplary view showing a method for processing outgoing information for an unreceived call according to an embodiment of the present invention.

As shown in FIG. 3, when a mobile terminal receives a mobile communication service in a roaming area, that is, a second mobile communication network, connection of an outgoing call to a mobile terminal roamed by the other mobile terminal of the first mobile communication network is performed. When requesting to the first exchange, the first exchange can request the connection of the outgoing call through the IRGS to the second exchange, so that the second exchange can request the connection of the outgoing call to the roaming mobile terminal (S310).

At this time, if the second exchange fails to connect the outgoing call to the roaming mobile terminal, it may determine that the roaming mobile terminal is incapable of receiving a call (S320). Accordingly, the second exchange may inform the IRGS that the roaming mobile terminal is in an unreachable state (S330).

The IRGS may check outgoing information for the unreceived call to the roaming mobile terminal, for example, outgoing time and outgoing telephone number (S340), and provide it to the service server (S350). In this case, the IRGS may check whether the roaming mobile terminal is subscribed to the catch call service, and may provide outgoing information on an unreceived call to the service server according to the subscription.

The service server may store the received outgoing information to be matched for each mobile terminal (S360).

4 is an exemplary diagram illustrating a method for providing a catch call service according to an embodiment of the present invention.

As shown in FIG. 4, when the mobile terminal enters the roaming area, that is, the second mobile communication network, into the first mobile communication network, it requests a location registration to the first HLR of the first mobile communication network (S410). 1 The HLR may perform location registration of the mobile terminal (S420).

The first HLR may confirm the termination of the international roaming service according to the location registration of the mobile terminal. The first HLR may determine the completion point of roaming of the mobile terminal as a point at which the location registration of the mobile terminal is completed (S430). Accordingly, the first HLR may calculate a roaming period of the mobile terminal based on the roaming start time and the roaming end time of the mobile terminal (S440).

In this case, the first HLR may inform the second HLR that the international roaming service of the mobile terminal has ended according to the location registration of the mobile terminal via the first GLR and the second GLR. Thus, the second HLR can cancel or delete the location registration of the mobile terminal generated during the roaming period.

In addition, the present invention calculates a roaming period based on the start time and the end time of the international roaming service in the first HLR, but is not necessarily limited to this, and is located on a path capable of confirming the start time and end time of the international roaming service. It can be performed in the service server as well as the first GLR.

The first HLR may provide the service server with the calculated roaming period to notify that the international roaming service for the mobile terminal has ended (S450). Accordingly, the service server may check the outgoing information related to the mobile terminal among the outgoing information on the unreceived call provided through the IRGS within the roaming period (S460) and request the message center to transmit a callback message for providing it (S470). .

When the message center receives a request for transmission of a callback message, the message center may generate a callback message including location information, for example, a Uniform Resource Location (URL), in which outgoing information about an unreceived call to the mobile terminal is generated (S480), and transmit it to the mobile terminal. There is (S490).

Eventually, the mobile terminal receives the callback message, and based on this, the user accesses and appropriately responds to the corresponding web page to check some or all of the outgoing information on the unreceived call or to check the details thereof. You can try sending a message.

As such, the present invention provides the mobile terminal with information on an outgoing call that is not received at the time when the location registration of the mobile terminal occurs in Korea, and induces a call connection based on this, thereby increasing sales from the mobile carrier's point of view. You can expect
