System and Method for Retransmitting MMS Receive Notification Message in Mobile Communication Network {SYSTEM AND METHOD FOR RE-TRANSMITTING MMS RECEIVE NOTIFICATION MESSAGE IN MOBILE COMMUNICATION NETWORK}

The present invention relates to a system and method for retransmitting an MMS reception notification message in a mobile communication network. In particular, the present invention retransmits an MMS reception notification message, which is forwarded to a call forwarding terminal, to a destination terminal, and receives an MMS reception notification message from a destination terminal to receive an MMS. The present invention relates to a system and method for retransmitting an MMS reception notification message in a mobile communication network, by which a callback URL included in the notification message is connected to receive an MMS message.

In general, a call forwarding service is a service for converting an incoming call received by the called terminal to a terminal that is already registered as a call forwarding terminal when the called terminal is busy or does not answer.

The call forwarding service as described above provides a call forwarding function for an SMS message as well as a call forwarding function for a voice call.

Meanwhile, due to the development of data transmission technology and an increase in transmission capacity, an MMS (Multimedia Messaging Service) capable of serving a multimedia message including various media such as photographs, videos, and music as well as text is provided.

When the MMS message is transmitted from the calling terminal to the called terminal, the MMS server sends an MMS receiving notification message in the form of SMS including a call back URL to the called terminal for confirmation by the terminal user. According to the user's attempt to access the MMS message, the MMS message is downloaded from the MMS server by accessing the callback URL included in the MMS reception notification message.

As described above, the receiving terminal receiving the MMS reception notification message is connected to the callback URL included in the MMS reception notification message to receive the MMS message from the MMS server. Conventionally, the destination terminal accesses the MMS server using the callback URL. The subscriber inquiry is performed with identification information of one called terminal, and the MMS message is downloaded only when the identification information of the called terminal connected to the MMS server and the identification information of the called terminal included in the MMS message coincide with each other.

However, when a call forwarding service is provided for an MMS message, the call forwarding terminal receiving the MMS reception notification message uses the callback URL included in the MMS reception notification message at the request of the terminal user who has confirmed the MMS reception notification message. Even if the terminal is connected to the MMS server, since the identification information of the call forwarding terminal connected to the MMS server and the identification information of the destination terminal included in the MMS message do not coincide with each other, the MMS message cannot be downloaded from the MMS server. .

In addition, the receiving terminal is also unable to receive the MMS reception notification message, there is a problem that can not download the MMS message from the MMS server.

The present invention has been made to solve the above-described problem, and if the message to be transferred to the destination terminal to the destination terminal subscribed to the call forwarding service for the MMS message, the message to be forwarded MMS reception notification message, MMS Since the MMS message cannot be received through the call forwarding terminal in the received notification message, the MMS message is transmitted by including information to receive the MMS message through the called terminal, leading to a state in which the called terminal can receive the MMS received notification message. When the terminal can receive the MMS reception notification message, the mobile communication network retransmits the MMS reception notification message to the called terminal so that the called terminal can access the callback URL included in the MMS reception notification message and receive the MMS message. System and method for retransmission of MMS reception notification message There is a purpose.

In order to achieve the above object, an MMS reception notification message retransmission system in a mobile communication network according to an embodiment of the present invention requests MMS reception notification message transmission to a called terminal in response to receiving an MMS message to be sent to a called terminal. An MMS server; When requesting the location information of the called terminal to the HLR according to the MMS reception notification message transmission request, and receiving the identification information of the call forwarding terminal in response thereto, confirms the location information of the call forwarding terminal, the call forwarding An SMSC for transmitting the MMS reception notification message to a terminal; Monitoring the state of the called terminal and when the called terminal is switched to a state capable of receiving the MMS reception notification message, notifying the SMSC that the called terminal is in a state capable of receiving the MMS reception notification message; And an HLR, wherein the SMSC retransmits the MMS reception notification message to the destination terminal when it is informed that the destination terminal has been switched to a state capable of receiving the MMS reception notification message, and the MMS server retransmits the MMS reception notification message. When the called terminal receiving the reception notification message connects to download the MMS message, it is preferable to transmit the MMS message to the called terminal.

Furthermore, when the SMSC sends the MMS reception notification message to the call forwarding terminal, the SMSC cannot receive the MMS message through the called terminal because the MMS message cannot be received by the call forwarding terminal. It is desirable to include information and transmit it.

And, when the SMSC requests the location information of the called terminal to the HLR to deliver the MMS received notification message to the called terminal, the SMSC requests the location information for the MMS received notification message to the location information request message. It is desirable to include an identifier indicating the transmission.

And, when the HLR informs the SMSC that the called terminal has been switched to a state capable of receiving the MMS reception notification message, it is preferable to provide the location information of the called terminal together.

On the other hand, MMS reception notification message retransmission method in a mobile communication network according to an embodiment of the present invention comprises the steps of creating an MMS reception notification message in the MMS server to the SMSC in response to receiving the MMS message to the destination terminal; Requesting location information of the called terminal from the SMSC by using the identification information of the called terminal included in the MMS reception notification message; Determining whether a state of the called terminal satisfies a call forwarding condition by the HLR in which the location information is requested, and when the call forwarding condition is satisfied, transmitting identification information of the call forwarding terminal to the SMSC; Checking the location information of the call forwarding terminal and transmitting the MMS reception notification message to the call forwarding terminal; When the HLR monitors the state of the called terminal and the called terminal is switched to a state capable of receiving the MMS receiving notification message, the SMSC switches to a state in which the called terminal can receive the MMS receiving notification message. Notifying the user that the request has been made; In response to the SMSC being notified from the HLR that the terminating terminal is in a state capable of receiving the MMS receiving notification message, it is preferable to include the step of retransmitting the MMS receiving notification message to the terminating terminal.

According to the MMS reception notification message retransmission system and method in the mobile communication network of the present invention, if the message to be forwarded to the call forwarding terminal is the MMS reception notification message, the MMS message cannot be received through the call forwarding terminal, so that the MMS message may be transmitted through the called terminal. The MMS reception notification message is transmitted by including information to receive the message, leading to the receiving terminal receiving the MMS reception notification message, and receiving the MMS reception notification message. By resending the reception notification message, the called terminal can access the callback URL included in the MMS reception notification message and receive the MMS message.

Hereinafter, an MMS reception notification message retransmission system and method in a mobile communication network according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a configuration of an MMS reception notification message retransmission system in a mobile communication network according to an embodiment of the present invention.

The calling terminal 10-1, the called terminal 10-2, and the call forwarding terminal 10-3 are terminals supporting MMS, and can create and receive MMS messages, and have a storage and management function of the MMS. .

The MMS message may be written not only in the calling terminal 10-1 but also in a personal computer 90, and connected to a content providing server 110 that provides various contents through the Internet 100. Select the desired multimedia content and use it to create an MMS message.

Meanwhile, according to the present invention, the receiving terminal 10-2 receiving the MMS reception notification message accesses the MMS relay 33 of the MMS server 30 through the callback URL included in the MMS reception notification message and receives the receiving terminal ( 10-2) to receive the MMS message requested to be transmitted.

The MMS server 30 is responsible for transmitting and receiving the MMS message, performs message format conversion and address format conversion, and transmits an MMS reception notification message informing of the reception of the MMS message to the destination terminal 10-2. do.

In addition, the MMS generates and transmits various guide messages (reception confirmation, transmission confirmation, etc.) according to MMS message processing to the calling terminal 10-1, the called terminal 10-2, and the call forwarding terminal 10-3. Perform message storage and management.

As described above, the MMS server 30 includes an MMS relay 33 and an MMS DB 35.

In such a configuration, when the MMS relay 33 receives the MMS message to be sent from the originating terminal 10-1 to the terminating terminal 10-2, the MMS relay 33 receives the MMS to the terminating terminal 10-2 by the VSMSS 50. The destination terminal 10-2, which requests to send a notification message and receives the MMS reception notification message, sends the MMS server 30 to the MMS server 30 with a callback URL included in the MMS reception notification message in order to download the MMS message sent to it. When the connection is attempted, the MMS message is transmitted to the connected destination terminal 10-2.

The MMS DB 35 stores and manages an MMS message received from the originating terminal 10-1 at the MMS relay 33.

On the other hand, the UA profile DB 40 and the terminal information (terminal model, detailed spec, supportable services, etc.) of the originating terminal 10-1 transmitting the MMS message and the destination terminal 10-2 receiving the MMS message and Terminal user information (service management number, identification information, additional service subscription details, etc.) is stored.

The VSMSS 50 creates an MMS reception notification message including a callback URL (URL for inducing a connection to the MMS relay) to be sent to the destination terminal 10-2 according to the request of the MMS relay 33 to the SMSC 70. send.

The transcoder 60 receives the MMS message through the UA profile DB 40 when the MMS relay 33 downloads the MMS message to the destination terminal 10-2 in association with the MMS relay 33. Searching for terminal information of (10-2) to determine whether the receiving terminal (10-2) is a terminal or more capable of receiving the MMS message to determine whether conversion to the MMS message is necessary, and the MMS message to the destination terminal ( If it is necessary to convert 10-2), the MMS message is converted to be optimized for the called terminal 10-2.

The HLR 80 is a database that stores and manages subscriber's personal information, service type, and terminal location registration information. The HLR 80 may determine a subscriber's validity and determine a subscriber's location through the HLR 80.

When the above-described HLR 80 receives the location information request message for requesting the location information of the destination terminal 10-2 to transmit the MMS reception notification message from the SMSC 70, the HLR 80 adds the destination terminal 10-2. If the corresponding terminal user is a call forwarding service subscriber for the MMS message, the call forwarding terminal is registered, and the call forwarding condition is satisfied, the SMSC 70 requesting the location information of the called terminal 10-2 based on the service information. Informs that the called terminal 10-2 is subscribed to the call forwarding service. Here, when the HLR 80 informs the SMSC 70 that the called terminal 10-2 is subscribed to the call forwarding service, the HLR 80 provides identification information of the registered call forwarding terminal 10-3 together. .

As described above, the HLR 80 indicating that the destination terminal 10-2 is subscribed to the call forwarding service to the SMSC 70 requesting the location information of the destination terminal 10-2 to transmit the MMS reception notification message. ) Monitors the state of the called terminal 10-2, and when the called terminal 10-2 is switched to a state capable of receiving an MMS reception notification message, the called terminal 10-2 is sent to the SMSC 70. ) Indicates that it has switched to a state capable of receiving an MMS reception notification message. Here, when the HLR 80 informs the SMSC 70 that the destination terminal 10-2 has switched to a state capable of receiving an MMS reception notification message, the HLR 80 provides location information of the destination terminal 10-2 together. .

On the other hand, when the SMSC 70 receives the MMS reception notification message from the VSMSS 50, the SMSC 70 uses the identification information of the destination terminal included in the MMS reception notification message to the HLR 80 of the destination terminal 10-2. When the location information request message for requesting location information is transmitted and the destination terminal 10-2 is notified that the destination terminal 10-2 is subscribed to the call forwarding service in response to the location information request from the HLR 80, the HLR 80 receives the message. The location information of the call forwarding terminal 10-3 is requested to the HLR 80 to which the call forwarding terminal 10-3 belongs using the identification information of the forwarding terminal 10-3 provided, and the HLR 80 is received. Transmits an MMS reception notification message to the call forwarding terminal 10-3 based on the location information of the call forwarding terminal 10-3 received in response to the location information request message, but forwards the call to the MMS reception notification message. The terminal 10-3 receives the MMS message. Since it is not possible, the terminal 10-2 includes the information to receive the MMS message and transmits the message.

Here, if the call forwarding terminal 10-3 notified from the HLR 80 is a terminal belonging to another mobile communication network, the SMSC 70 may transmit location information to the HLR of the corresponding mobile communication network to which the call forwarding terminal 10-3 belongs. Send the request message.

In addition, the SMSC 70 notifies that the destination terminal 10-2 is subscribed to the call forwarding service from the HLR 80 in response to the location information request of the destination terminal 10-2 to which the MMS reception notification message is to be transmitted. If received, the MLR reception notification message is transmitted to the call forwarding terminal 10-3 based on the received location information by requesting the location information of the call forwarding terminal 10-3 to the HLR 80, and then the HLR 80. If the receiving terminal 10-2 is reported that the transition to the state capable of receiving the MMS reception notification message from the), when the receiving terminal 10-2 is reported that the transition to the state capable of receiving the MMS reception notification message The MMS reception notification message is retransmitted to the called terminal 10-2 based on the location information of the called terminal 10-2 provided together.

2 is a flowchart illustrating a method of retransmitting an MMS reception notification message in a mobile communication network according to an embodiment of the present invention.

First, a calling terminal user who wants to send an MMS message to the called terminal 10-2 may use the MMS message production tool installed in the calling terminal 10-1 or a personal computer or at the calling terminal 10-1 itself or the content. After connecting to the providing server to create an MMS message (S10), the created MMS message is transmitted to the MMS server 30 (S12).

After receiving the MMS message through the process S12, the MMS server 30 checks identification information of the calling terminal and identification information of the called terminal included in the MMS message, and stores the received MMS message in the MMS DB 35. Then, it requests the VSMSS 50 to transmit the MMS reception notification message to the called terminal 10-2 (S14).

The VSMSS 50, which has been requested to transmit the MMS reception notification message from the MMS server 30 through the process S14, creates an MMS reception notification message including a callback URL and transmits it to the SMSC 70 (S16).

The MMS reception notification message generated in step S16 includes identification information of the called terminal 10-2.

The SMSC 70 that has received the MMS reception notification message through the process S16 uses the identification information of the destination terminal 10-2 included in the MMS reception notification message to the destination terminal 10-2. Transmits a location information request message for requesting location information (S18).

When the SMSC 70 transmits the location information request message to the HLR 80 in order to transmit the MMS reception notification message received from the VSMSS 50 in step S18, the location information is transmitted for transmission of the MMS reception notification message. It is desirable to include an identifier indicating that the request is made.

If the HLR 80 receiving the location information request message from the SMSC 70 through the above process S18 includes the identifier indicating that the location information request message requests the location information for the MMS reception notification message transmission, the location information The user terminal 10-2 is subscribed to the call forwarding service for the MMS message by checking the user profile information of the called terminal 10-2 with the identification information of the called terminal 10-2 included in the request message. When it is confirmed by the terminal (S20), it is determined whether the call forwarding condition is satisfied, and when the call forwarding condition is satisfied (S22), the identification information of the call forwarding terminal 10-3 in response to the location information request to the SMSC 70 Transmit (S24).

In the above-described process S22, the call forwarding condition may be a time when the power supply of the called terminal 10-2 is turned off, a forced call forwarding is set by the user, or the call forwarding is designated.

The SMSC 70, which has received the identification information of the call forwarding terminal 10-3 from the HLR 80 through the process S24, transfers the call forwarding terminal to the HLR 80 to which the call forwarding terminal 10-3 belongs. 10-3) and transmits a location information request message for requesting location information (S26), and receives a location information response message, which is a response message to the location information request message, from the HLR 80 (S28).

The SMSC 70 receiving the location information response message through the process S28 is included in the location information response message and is transferred to the call forwarding terminal through the mobile communication network 20 based on the location information of the call forwarding terminal 10-3. In step S30, the MMS reception notification message is transmitted.

When the MMS reception notification message is transmitted to the call forwarding terminal 10-3 through the above process S30, the SMSC 70 cannot receive the MMS message from the forwarding terminal 10-3 in response to the MMS reception notification message. Including the information to receive the MMS message through the destination terminal (10-2) and transmits.

The call forwarding terminal 10-3 receiving the MMS reception notification message through the process S30 may notify the terminal user of the MMS reception notification message through a ring tone or vibration so that the terminal user can check the MMS reception notification message. For example, the terminal user who acknowledges the MMS reception notification message according to the reception of the MMS reception notification message may receive the MMS message from the destination terminal 10-2 in order to receive the MMS message to the destination terminal 10-2 based on the MMS reception message. The reception notification message is made available for reception (e.g., powered on).

On the other hand, the HLR 80 which has transmitted the identification information of the call forwarding terminal 10-3 in response to the location information request to the SMSC 70 through the process S24 from the SMSC 70 through the process S18 described above. If the message to be forwarded to the call forwarding terminal 10-3 based on the identifier included in the received location information request message (an identifier indicating that the location information is requested for transmission of the MMS reception notification message) is an MMS reception notification message. Monitoring the state of the called terminal 10-2 so that the MMS reception notification message can be delivered to the called terminal 10-2, and the called terminal 10-2 is powered on or the call forwarding is released. When the terminating terminal 10-2 is switched to a state capable of receiving an MMS reception notification message (S32), the terminating terminal 10-2 is switched to a state in which the terminating terminal 10-2 can receive an MMS receiving notification message by the SMSC 70. Notify that (S34).

When the HLR 80 informs the SMSC 70 that the destination terminal 10-2 has switched to a state capable of receiving an MMS reception notification message through step S34, the location information of the destination terminal 10-2. Comes with.

The SMSC 70 notified that the terminating terminal 10-2 has switched to a state capable of receiving an MMS reception notification message from the HLR 80 through the above process S34 is notified by the terminating terminal 10-2 of the MMS receiving notification. When receiving a report that the message has been switched to a state capable of receiving a message, the MMS reception notification message is retransmitted to the called terminal 10-2 based on the location information of the called terminal 10-2 provided together (S36).

The receiving terminal 10-2 receiving the MMS reception notification message through the process S36 may use the MMS server as a callback URL included in the MMS reception notification message according to a terminal user's attempt to access the received MMS reception notification message. 30) and requests the download of the MMS message (S38).

The MMS server 30 which has received the request for downloading the MMS message through the process S38 is included in the identification information of the called terminal 10-2 requesting the download and the MMS message requested by the called terminal 10-2 for downloading. It checks whether the identification information of the called terminal 10-2 coincides with each other, and downloads the MMS message to the called terminal 10-2 only when the two identification information match each other (S40, S42).

When the MMS server 30 downloads the MMS message to the called terminal 10-2 in step S42, the receiving terminal 10-2 can receive the MMS message in association with the transcoder 60. After confirming that the terminal is the above, when it is necessary to convert the MMS message to the destination terminal (10-2), it is preferable to download after converting the MMS message to be optimized for the destination terminal (10-2).

The receiving terminal 10-2, which has downloaded the MMS message through step S42, stores each multimedia content included in the MMS message in a memory area, and when the content storage is completed, replays the MMS message.
