Description

System for supporting mass sending service and method

The present invention relates to a system and method for providing mass shipment service.

In general, a mass dispatch service is a service that registers a mobile terminal based on a cellular telephone number (CTN) and sends the message to the corresponding mobile terminal at a predetermined time when a mass message is requested. For example, such as a disaster, an event, and a reservation. It is widely used for message transmission. For example, the bulk dispatch service can send about 20 to 30 messages per minute, but because it transmits messages in a queue method, it is impossible to simultaneously send messages due to the nature of sending messages sequentially. There is a problem that a difference occurs at the time of reception.

In particular, since such a mass-distribution service has difficulty in smoothly transmitting an increasing number of messages, in order to solve this problem, cell-based broadcast transmission is performed in a wireless network by using a system expansion or cell broadcasting method. An alternative is proposed.

However, this method also increases the operating costs due to the expansion of the system and allocates a separate channel for cell broadcasting. In particular, all mobile terminals in a wireless network occupy separate channels for cell broadcasting. This can result in a waste of limited network resources. The mobile terminal also requires a separate function development and verification to implement such a function may require a lot of time and cost. Therefore, there is a need for a method for mass sending of messages more efficiently.

The present invention is to solve the above problems, and to create a multicasting transmission table including at least one parameter for performing authentication of the mobile terminal included in the multicasting group and to send a message to the mobile terminal based on this By multicasting, to provide a system and method for providing a mass-sending service that can mass-send a message more efficiently.

An object of the present invention is to provide a system and a method for providing a mass dispatch service that facilitates implementation of a system by providing a message multicasting based on mobile IPv6.

In addition, the present invention creates a multicasting transmission table including at least one parameter for performing authentication of a mobile terminal included in a multicasting group, and multicasts a message only to the corresponding mobile terminal based thereon, thereby limiting wireless network resources. The present invention provides a system and method for providing a bulk shipping service that can prevent the waste of.

To this end, a system for providing a mass dispatch service according to an aspect of the present invention creates a multicasting transmission table including at least one parameter for performing authentication of a mobile terminal belonging to a multicasting group and creates the multicasting table. A mass dispatch center requesting a message service center for a message multicasting for the mobile terminal based on a transmission table, and a message for multicasting a message to the mobile terminal in response to a request of the mass dispatch center and providing a response message thereto. It may include a service center.

According to another aspect of the present invention, there is provided a system for providing a mass dispatch service, including: a database storing a multicasting transmission table including at least one parameter for performing authentication of a mobile terminal belonging to a multicasting group; And a multicasting processor configured to multicast a message to the mobile terminal based on the multicasting transmission table.

According to another aspect of the present invention, there is provided a method for providing a mass dispatch service, comprising: creating a multicasting transmission table including at least one parameter for performing authentication of a mobile terminal belonging to a multicasting group; Requesting a message service center for message multicasting for the mobile terminal based on a casting transmission table, wherein the message service center may multicast the message and receive a response message thereto.

In addition, a method for providing a mass dispatch service according to another aspect of the present invention comprises the steps of: creating a multicasting transmission table including at least one parameter for performing authentication of a mobile terminal belonging to a multicasting group; Multicasting a message to the mobile terminal based on the multicasting transmission table, and receiving a response message as authentication of the mobile terminal receiving the message is successful.

Hereinafter, a system and a method for providing a mass dispatch service according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 6.

The present invention proposes a method for providing a mass dispatch service based on mobile IPv6 (MIPv6). That is, the present invention may create a multicasting transmission table including at least one parameter for performing authentication of the mobile terminal included in the multicasting group, and multicast the message to the mobile terminal based on the multicasting transmission table.

In this case, mobile IPv6 may refer to a technology capable of communicating while the user moves from one service zone to another service zone while maintaining the original IP address. In particular, mobile IPv6 supports an environment where mobile users can get the information they want, so they can expect the convenience of use, access to the network according to the mobility, and can be fully compatible with existing Internet protocols. There is an advantage.

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 may include a mobile terminal 110, a message service center 120, a service server 130, an authentication server 140, a mass dispatch center 150, and the like. have.

The service server 130 is a server capable of providing various services through the wired / wireless internet. For example, the service server 130 may mean a web server or a content server for providing a web service or a content service. The service server 130 may provide an advertisement or promotional message related to a service provided by the service server to a mobile terminal subscribed to the service. In this case, the message may be provided as a Short Message Service (SMS), a Long Message Service (LMS), a Multimedia Message Service (MMS), an E-mail, or the like according to the size or characteristics of an advertisement or promotional content to be provided.

The mass dispatch center 150 may receive a mass dispatch of a message from a service server and request multicasting of a message based on the mobile IPv6. In brief, when the mass dispatch center 150 receives a request for transmitting a message from a service server, the mass transmission center 150 receives the IP and the International Mobile Station Identity (IMSI) of the at least one mobile terminal for providing the service from the authentication server 140. A multicasting group IP may be assigned based on the received mobile terminal's IP and IMSI, and a session key may be generated for the data session. The mass dispatch center 150 may create a separate multicasting transmission table that includes the mobile terminal's IP, IMSI and multicasting group IP and session key. Therefore, the mass dispatch center 150 may request the multicasting of the message to the mobile terminal included in the multicasting group based on the created multicasting transmission table.

In this case, the authentication server 140 may mean an AAA (Authentication, Authorization, Accounting) server.

The message service center 120 may receive a message including a part or all of the multicasting transmission table from the mass distribution center and multicast the message to the corresponding mobile terminal through the base station. In addition, the message service center 120 may perform the same role as a mass distribution center, that is, by receiving a request for multicasting of a message from a mobile terminal, creating a multicasting transmission table and multicasting a message directly based on the message. have.

Of course, since the message transmitted from the message service center is generally transmitted using the IP of the multicasting group as the destination address, when the base station receives the message from the message service center, it first uses IGMP (Internet Group Management Protocol). After allocating a channel for multicasting with all mobile terminals belonging to the multicasting group, the corresponding message may be transmitted through the allocated channel.

In this case, the mass dispatch center 150 or the message service center 120 includes at least one parameter corresponding to each mobile terminal, for example, an IP of the mobile terminal, an IP of a multicasting group, an IMSI, and a session key. Multicasting transmission table can be stored and managed in a separate database.

When the mobile terminal 110 receives a message from the message service center, the mobile terminal 110 may perform authentication and provide a response message or a reject message in response thereto. That is, the mobile terminal 110 performs authentication to confirm whether the user is a legitimate user to receive the message based on the parameters included in the message. When the authentication succeeds, the mobile terminal 110 generates a response message and provides the response. If it fails, you can provide a reject message. The mobile terminal is a device capable of transmitting and receiving messages, and may be a concept encompassing a mobile phone, a personal digital assistant (PDA), a notebook, and the like.

2 is a first exemplary diagram illustrating a method for providing a mass dispatch service according to an embodiment of the present invention.

As shown in FIG. 2, when the service server requests mass shipment of a message to the mass distribution center, that is, multicasting (S210), the mass distribution center includes at least one parameter for performing authentication of the mobile terminal. A multicasting transmission table can be created (S220). To this end, the mass dispatch center may request and receive information on mobile terminals subscribed to the mass dispatch service, for example, IP and IMSI, as at least one parameter to be included in the multicasting transmission table. Here, the IP of the mobile terminal may mean a home IPv6 based HoA (Home of Address).

The mass distribution center may then assign, for example, a multicasting group IP and generate a session key for the data session based on the mobile terminal IP and IMSI. Here, the session key can be generated by a combination of the mobile terminal IP and IMSI, because it is advantageous in security to provide the session key rather than simply providing IP or IMSI.

In this case, the present invention is not limited to the method for generating the session key by the combination of the mobile terminal IP and the IMSI, but can be applied to various encryption parameters for performing the authentication of the mobile terminal as well as to a general encryption algorithm. For example, it may be generated using a hash function.

When the creation of the multicasting transmission table is completed, the mass distribution center may provide a message service center with a message including a part or all of the multicasting transmission table, for example, the mobile terminal IP, the multicasting group IP, and the session key. Multicasting may be requested (S230). Therefore, the message service center may multicast the received message to the corresponding mobile terminal through the base station (S232).

When the mobile terminal receives the message, the mobile station may extract the parameters included in the received message, that is, the mobile terminal IP, the multicasting group IP, and the session key, and perform authentication based on the extracted message (S240). For example, the mobile terminal can perform the authentication by decrypting the session key using a predetermined key to extract the mobile terminal IP and IMSI and confirming that the extracted mobile terminal IP and IMSI match their terminal information. Thus, if authentication is successful according to the authentication result, the mobile terminal may generate a response message for informing this and provide the response message to the mass dispatch center through the message service center (S250).

On the other hand, if the authentication fails, the mobile terminal may generate a rejection message for rejecting the transmission of the message and provide the rejection message to the mass distribution center through the message service center. For example, such a reject message may be generated when the mobile terminal IP is changed due to the number porting of the subscriber.

When receiving the response message, the mass dispatch center may delete the session key included in the multicasting transmission table and set that the transmission of the message to the corresponding mobile terminal is completed (S260). On the other hand, when the mass distribution center receives the rejection message, it determines that the mobile terminal is not a subscriber to the mass-sending service, and thus IMSI, multicasting group IP, and session key corresponding to the mobile terminal IP included in the multicasting transmission table. You can delete all of them.

As such, the present invention creates a multicasting transmission table including at least one parameter for performing authentication of a mobile terminal belonging to a multicasting group, and multicasts a message to the mobile terminal based on the created multicasting transmission table. This allows mass mailings to be sent more efficiently. In addition, the present invention can facilitate the implementation of the system by providing a message multicasting based on mobile IPv6.

3 is a second exemplary diagram illustrating a method for providing a mass dispatch service according to an embodiment of the present invention.

As shown in FIG. 3, when the service server requests mass shipment of a message to the mass distribution center, that is, multicasting (S310), the mass distribution center includes at least one parameter for performing authentication of the mobile terminal. The transmission table may be created (S320).

To this end, the mass dispatch center may request information of a mobile terminal subscribed to the mass dispatch service, for example, IP and IMSI, as a parameter to be included in the multicasting transmission table, and receive the information from the authentication server. The mass distribution center may then assign, for example, a multicasting group IP and generate a session key for the data session based on the mobile terminal IP and IMSI.

When the creation of the multicasting transmission table is complete, the mass transit center may provide the message service center with a message including part or all of the multicasting transmission table, for example, mobile terminal IP, multicasting group IP, and session key, to multiply the message. Casting may be requested (S330). Thus, the message service center may multicast the received message to the corresponding mobile terminal (S332).

At this time, when the mobile terminal is in a state where reception is impossible such as being turned off or located in a shadowed area, the mobile terminal cannot receive a message. Thus, if the mass dispatch center does not receive any response from the mobile terminal, that is, if it does not receive a response message or a reject message, it may determine that the mobile terminal is in an incapable state.

The mass dispatch center may perform retransmission of a message for a mobile terminal that has not received a message, that is, reassign a multicasting group IP for retransmission of a message for a mobile terminal that is in an unreceived state ( S340). Thus, the bulk dispatch server rebuilds the multicasting delivery table that contains the reassigned multicasting group IP and requests the message service center to multicast the message by providing the message service center with a message that includes some or all of the rewritten multicasting delivery table. It may be (S350). Therefore, the message service center may retransmit, ie, multicast, the received message to the corresponding mobile terminal through the base station (S352).

In this case, the mass distribution center may retransmit, that is, multicast, the message at regular intervals.

As such, the present invention creates a multicasting transmission table including at least one parameter for performing authentication of mobile terminals belonging to a multicasting group and multicasts a message only to the corresponding mobile terminal based on the created multicasting transmission table. It is also possible to prevent waste of limited wireless network resources.

In addition, the present invention has been described with reference to a mass dispatch center and a message service center as an embodiment, but is not limited to one multicasting service center that can manage the multicasting transmission table and multicast messages based thereon. You can also apply

4 is a third exemplary diagram illustrating a method for providing a mass dispatch service according to an embodiment of the present invention.

As shown in FIG. 4, when the sending mobile terminal sends a large number of messages to the multicasting service center, that is, requests multicasting (S410), the multicasting service center provides at least one parameter for performing authentication of the mobile terminal. It is possible to create a multicasting transmission table to be included (S420).

To this end, the multicasting service center is a parameter to be included in the multicasting transmission table. The multicasting service center may request information of mobile terminals subscribed to the mass dispatch service, for example, IP and IMSI, to the authentication server and receive it. The multicasting service center may allocate a multicasting group IP and generate a session key for a data session based on the mobile terminal IP and IMSI.

When the creation of the multicasting transmission table is completed, the multicasting service center generates a message including part or all of the multicasting transmission table, for example, the mobile terminal IP, the multicasting group IP, and the session key, and transmits the message through the base station. It may multicast to the receiving mobile terminal (S430).

Upon receiving the message, the receiving mobile terminal may extract the mobile terminal IP, the multicasting group IP, and the session key included in the received message and perform authentication based on the extracted mobile terminal (S440). That is, if authentication is successful according to the result of performing authentication, the receiving side mobile terminal may generate a response message for notifying it and provide it to the multicasting service center (S450). On the other hand, if authentication fails, the receiving mobile terminal may generate a reject message for rejecting the message and provide the same to the multicasting service center.

When the multicasting service center receives the response message, the multicasting service center may delete the session key included in the multicasting transmission table to indicate that the transmission of the message to the corresponding mobile terminal is completed (S460). On the other hand, when the multicasting service center receives the rejection message, the multicasting service center determines that the receiving mobile terminal is not a subscriber subscribed to the mass-sending service, and the corresponding mobile terminal IP included in the multicasting transmission table, the corresponding IMSI, and the multicasting group. You can delete all IP and session keys.

5 is a fourth exemplary diagram illustrating a method for providing a mass dispatch service according to an embodiment of the present invention.

As shown in FIG. 5, when the sending mobile terminal sends a large number of messages to the multicasting service center, that is, requests multicasting (S510), the multicasting service center provides at least one parameter for performing authentication of the mobile terminal. It is possible to create a multicasting transmission table to be included (S520).

To this end, the multicasting service center is a parameter to be included in the multicasting transmission table. The multicasting service center may request information of mobile terminals subscribed to the mass dispatch service, for example, IP and IMSI, to the authentication server and receive it. The multicasting service center may allocate a multicasting group IP and generate a session key for a data session based on the mobile terminal IP and IMSI.

When the creation of the multicasting transmission table is completed, the multicasting service center generates a message including part or all of the multicasting transmission table, for example, the mobile terminal IP, the multicasting group IP, and the session key, and transmits the message through the base station. Multicasting to the receiving mobile terminal may be performed (S530).

At this time, when the mobile terminal is in a state where reception is impossible such as being turned off or located in a shadowed area, the mobile terminal cannot receive a message. Thus, if the multicasting service center does not receive any response from the receiving mobile terminal, that is, if it does not receive a response message or a reject message, the multicasting service center may determine that the receiving mobile terminal is in an incapable state.

The multicasting service center may perform retransmission of the message to the receiving mobile terminal that did not receive the message, that is, recast the multicasting group IP for retransmission of the message to the receiving mobile terminal in the unreceived state. Can be assigned (S540). Therefore, the multicasting service center may rewrite the multicasting transmission table including the reassigned multicasting group IP and retransmit, that is, multicast the message to the receiving mobile terminal based on the multicasting transmission table (S550).

In this case, the multicasting service center may retransmit, that is, multicast, the message every predetermined period.

6 is an exemplary view showing a detailed configuration of a multicasting service center according to an embodiment of the present invention.

As illustrated in FIG. 6, the multicasting service center according to the present invention may include a receiver 610, a multicasting processor 620, a transmitter 630, a database (DB) 640, and the like.

You can create multicasting transmission tables that include IMSI, multicasting group IPs, session keys, and so on.

In this case, the multicasting transmission table thus created may be stored in the database 640.

When the creation of the multicasting transmission table is completed, the multicasting processing unit 640 generates a message including a part or all of the multicasting transmission table, for example, the IP of the receiving mobile terminal, the multicasting group IP, and the session key. When this is transmitted to the base station through the transmitter 630, the base station may multicast it to the corresponding mobile terminal.
