System and providing message service of mobile terminal during global roaming and method

The present invention relates to a system and method for providing a message service of a mobile terminal during international roaming.

In general, international roaming service is a service that allows a user of a domestic mobile terminal to use the mobile terminal in the same country when visiting overseas. The number of users is increasing as automatic roaming becomes available overseas.

The user of such an international roaming service uses services such as voice and video calls, data transmission, and message transmission according to agreements between roaming providers and pays the usage fee accordingly. In particular, voice and video calls and SMS message transmission are provided through a circuit switched network or a CS (Circuit Switching) network, and data transmission, LMS and MMS message transmission are provided through a packet switched network or a packet switching (PS) network.

Hereinafter, a process of receiving an LMS message and an MMS message through a packet switching network of the prior art (registered patent publication 10-0851582) among the message services will be described with reference to FIG. 1.

1 is an exemplary view showing a method for providing a message service according to the prior art.

As shown in Figure 1, when the originating terminal of the home network according to the prior art transmits the palm print data, that is, LMS or MMS message to the palm print data server (S101), when the palm print data server receives the palm print data, The location of the called terminal can be confirmed through the location register (S102). As a result of the checking, if the receiving terminal is roaming internationally, the palm print data server may check whether the receiving terminal receives the long palm data during international roaming, that is, whether to allow reception or prohibit reception (S103).

The palm print data server may transmit a palm print notice message to notify the receiving terminal of the visitor network through the SMS server according to the permission of the palm print data (S104).

The called terminal may inform the user that there is a message to receive by displaying the received palm print message (S105). Based on this, the user of the destination terminal of the visitor network can select whether or not to receive the message. That is, if the user selects to accept the message, the destination terminal accesses the long data server of the home network according to the selection of the acceptance. By requesting data (S106), the palm print data server may transmit the palm print data, that is, the LMS message or the MMS message to the called terminal (S107).

Since the called terminal of the visitor network needs to download the LMS message or the MMS message by accessing the long-term data server of the home network through the packet switched network, the usage fee due to the download is charged. It depends on.

In this case, the LMS message is more than SMS, for example, 80 bytes or more and less than 1k bytes in size, but since the MMS message includes multimedia data such as images or videos as well as text, its size is relatively larger than that of LMS messages. Usage charges also occur a lot.

However, the existing SMS_Noti message simply notifies that there is a message to be received, and does not distinguish whether the message to be received is an LMS message or an MMS message, and thus the user cannot know the fact even if the SMS_Noti message is received. Moreover, even though the message to be received is an LMS message, the user often thinks that the message is a relatively expensive MMS message, and thus does not allow the message. Sometimes.

The present invention is to solve the above problems of the prior art, when a message is received from the mobile terminal of the home network to the message center, by notifying the mobile terminal of the visitor network, even the type of message, the user convenience of receiving it The present invention provides a system and a method for providing a message service of a mobile terminal during international roaming.

In addition, the present invention is a system for providing a message service of a mobile terminal during international roaming to reduce the charges due to the incoming message because it is possible to selectively receive the message by the prior notification of the message type and its To provide a method.

In addition, the present invention provides a message service of a mobile terminal during international roaming, which enables selective reception of messages by prior notification of message types during international roaming, thereby enabling the activation of relatively inexpensive message services. The present invention provides a system and a method thereof.

To this end, a system for providing a message service during international roaming according to an aspect of the present invention is located in a first mobile communication network through a packet switched network and receives a message from a first mobile terminal in the first mobile communication network. A message center for confirming the type of the received message and notifying at least one second mobile terminal of a second mobile communication network through a circuit switched network that there is a predetermined type of the message to be received according to the result of the checking; And a database storing the received message.

According to another aspect of the present invention, a mobile terminal in a second mobile communication network that receives a message from a message center in a first mobile communication network includes: a memory configured to store whether a message is automatically received according to a user's selection; And a controller for determining whether the message is automatically received based on an identifier included in the received SMS message when receiving an SMS message indicating that there is a message to be received from the message center. have.

According to another aspect of the present invention, a method for providing a message service during international roaming includes receiving and storing a message from a first mobile terminal of a first mobile communication network; And notifying at least one second mobile terminal of the second mobile communication network through the circuit switched network that there is a predetermined kind of the message to be received.

Hereinafter, a system and a method for providing a message service of a mobile terminal during international roaming according to an embodiment of the present invention will be described in detail with reference to FIGS. 2 to 8. That is, when the message is received from the mobile terminal of the home network in the message center, the present invention notifies the mobile terminal of the visitor network that there is a predetermined type of message to be received, for example, an LMS message, an MMS message, an e-mail, and the like. Allow users at to selectively receive messages. In an embodiment to be described later, the above-mentioned 'first mobile communication network' may correspond to a 'home network', and the above-mentioned 'second mobile communication network' may correspond to a 'visited network'. have.

As shown in FIG. 2, a system according to an embodiment of the present invention includes a first mobile terminal 211, a message center 212, and a gateway location register (GLR) 213 within a first mobile communication network 210. ) And Mobile Switching Center (MSC) 221, Serving GPRS Support Node (SGSN) 222 and second mobile terminal 223 in the Gateway GPRS Support Node (GGSN) 214 and the second mobile communication network 220. ) And the like.

In this case, the first mobile terminal 211 and the second mobile terminal 223 are all devices capable of message service through a mobile communication network during international roaming, and include a mobile phone, a personal digital assistant (PDA), a laptop, and the like. Can be.

The first mobile terminal 211 in the first mobile communication network 210, which is a home network, may include, for example, a message including at least one of data such as text, voice, image, video, and the like, in particular, an LMS message, The MMS message and the e-mail may be transmitted to the second mobile terminal 223 in the second mobile communication network 220 which is the visitor network.

In particular, the second mobile terminal 223 according to the present invention may receive an SMS type guide message including an announcement message for informing the reception of the LMS message or the MMS message before the reception of the LMS message or the MMS message. . Therefore, the second mobile terminal 223 displays the type of message to be received so that the user can know, for example, an LMS message or an MMS message, according to the guide text included in the guide message, and based on this, whether to download the corresponding message from the user. Can be selected.

To this end, when the message center 222 receives a message from the first mobile terminal 211 in the first mobile communication network 210, the message center 222 checks the type of the received message and according to the result of the checking, selects a predetermined type, for example. To generate an SMS type announcement message for notifying that there is a message such as an LMS message or an MMS message or an e-mail, and the generated announcement message is a circuit switched network, that is, a GLR 213, an SS7 signaling network, an MSC 221, or the like. Through at least one second mobile terminal 223 of the second mobile communication network 220 may be transmitted to notify. In particular, the message center 212 according to the present invention may transmit and notify a guide message including guide text for not only receiving a message but also notifying the type of the message.

In this case, the message center 212 may further include an identifier for identifying the type of the message in the header of the guide message as well as the guide text indicating the type of the message.

The message center 212 may store and manage the received LMS message or MMS message in a database. Therefore, the message center 222 connects to the database when the second mobile terminal 223 receiving the guide message accesses the packet switched network, that is, the SGSN 222, the GPRS Roaming eXchange (GRX) network, or the GGSN 214. The stored LMS message or MMS message may be provided.

In this case, although the message center 212 according to the present invention may be provided as one physical device regardless of the type of message, it may be provided separately according to the type of message as needed. For example, LMS (Long Message) It may be configured to include a first server for processing a Service (Message) or multimedia message service (MMS) message and a second server for processing a Short Message Service (SMS) message.

Meanwhile, although the present invention has been described assuming that the first mobile communication network is the home network and the second mobile communication network is the visitor network, the present invention is not limited thereto, and the second mobile communication network is the visitor network. Each can be assumed as a home network, but the process is the same.

3 is a first exemplary diagram illustrating a method for providing a message service according to an embodiment of the present invention.

As shown in FIG. 3, when a first mobile terminal in a first mobile communication network, which is a home network, composes a message and transmits a message created through a packet switched network (S301), the header of the message identifies the type of the message. An identifier may be included.

For example, if the mobile terminal includes only text of 80 bytes or more, which is the maximum capacity of an SMS message, the mobile terminal recognizes the text as an LMS message. The mobile terminal further includes not only text but also various multimedia data such as an image or a video. If it is recognized as an MMS message, an identifier for identifying the message may be included in the header of the message.

The message center can receive the message and store it in the database. The message center checks the type of the message through the identifier included in the header of the received message (S302) and transmits to the second mobile terminal of the second mobile communication network that there is a predetermined type of message to be received according to the result of the checking. An SMS-type guide message, for example, an SMS_Noti message, may be generated to notify the user (S303). The SMS_Noti message may include location information for receiving a message to be received, for example, a URL (Uniform Resource Locator), as well as guide text for indicating that there is an LMS or MMS message to be received.

In this case, the message center may further transmit an identifier for identifying an LMS or MMS message to be received in the header of the SMS_Noti message.

The message center may transmit the generated SMS_Noti message to the second mobile terminal via the GLR of the first mobile communication network, the SS7 signaling network, the MSC of the second mobile communication network, etc. (S304). Then, the second mobile terminal can inform the user that there is a predetermined type of message to be received based on the SMS_Noti message, which will be described with reference to FIG. 3.

4 is an exemplary view showing a screen of a mobile terminal according to an embodiment of the present invention.

As shown in FIG. 4, upon receiving the SMS_Noti message through the circuit switched network, the second mobile terminal according to the present invention may display that there is a predetermined type of message to be received based on the identifier included in the received SMS_Noti message. It may be (S305). For example, a long text (LMS) message was received from '0123456789' on the screen of a mobile terminal. Would you like to receive it now? '

Through such a guide phrase, the user of the second mobile terminal can easily identify the type of message to be received, and can selectively determine whether to receive the message based on this. That is, the present invention may induce a user to receive an LMS message, which is relatively cheaper to use than an MMS message, through the announcement text.

Thereafter, the second mobile terminal in the second mobile communication network, which is the visitor network, may allow or reject the reception of the LMS message or the MMS message through a menu or a key selection by the user. That is, if the user allows the reception of the LMS message or the MMS message, the second mobile terminal is based on the location information included in the guide message, the packet switching network, that is, the SGSN, GRX network of the second mobile communication network, the first mobile communication The message can be requested by accessing the message center via the GGSN of the network. Thus, the message center may provide the corresponding message stored in the database to the second mobile terminal (S307).

At this time, the SGSN is a data network switch, and can monitor the location of the mobile terminal and perform security technology and access control functions. Can be. The GGSN is an Internet gateway switch, and can support packet data services by interworking with the SGSN of the first mobile communication network.

As such, when the message is received from the mobile terminal of the home network at the message center, the present invention notifies the mobile terminal of the visitor network that there is a predetermined type of message to be received, for example, an LMS message, an MMS message or an e-mail. The convenience of the receiving user can be improved.

In addition, since the present invention can selectively receive the message by the prior notification of the type of message to be received, it is possible to reduce the usage fee according to the incoming message, thereby activating a relatively low-cost message service It may be.

As shown in FIG. 5, the message center 212 according to the present invention may include a transceiver 510, a generator 520, a checker 530, a database 540, and the like.

When the confirmation unit 530 receives a message transmitted from the first mobile terminal in the first mobile communication network, the confirmation unit 530 may check the type of the received message, for example, an LMS message, an MMS message, an electronic mail, and the like. The type of message can be checked through the identifier included in the header of the.

The generation unit 520 may generate and transmit an SMS_Noti message to include different preset guide phrases according to the identified message type. In addition, the generation unit 520 may further include an identifier for indicating the type of the message to be received in the header of the SMS_Noti message.

The database 540 may store the received message and provide the corresponding message when the second mobile terminal receiving the SMS_Noti message is connected.

The transceiver 510 receives a message from the first mobile terminal and transmits the message to the second mobile terminal, and transmits a message, in particular, an SMS_Noti message generated according to reception of an LMS message or an MMS message, at least in the second mobile communication network. It can transmit to each one second mobile terminal.

6 is a second exemplary diagram illustrating a method for providing a message service according to an embodiment of the present invention.

As shown in FIG. 6, the message center according to the present invention includes a first server and a second server, which is the same as described in FIG. 3, and the first server and the second server interwork with each other to generate an SMS_Noti message. Only differences in the transmission process will explain this.

The first mobile terminal in the first mobile communication network, which is the home network, may create a message, for example, an LMS or MMS message, and transmit the message to the first server through the packet switched network (S601).

The first server may receive the message and store it in a database. The first server checks the type of the message through the identifier included in the header of the received message (S602), and the second mobile terminal of the second mobile communication network indicates that there is a predetermined type of message to be received according to the result of the checking. An SMS-type guide message for transmitting and notifying, for example, an SMS_Noti message may be generated (S603).

When the first server provides the generated SMS_Noti message to the second server, the second server sends the received SMS_Noti message to the GLR of the first mobile communication network, the SS7 signaling network, and the MSC of the second mobile communication network. It can be transmitted to at least one second mobile terminal (S604).

In addition, the message center according to the present invention may further transmit an identifier for identifying an LMS or MMS message to be received in the header of the SMS_Noti message, and transmits the message by using the identifier. It demonstrates with reference to 8.
