Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a system for providing a message service according to an embodiment of the present invention.

As shown in FIG. 1, the message service providing system 100 according to an embodiment of the present invention includes a terminal 110, a base station 115, an exchanger 120, a home location register 125, and a first message sending device. 130 and the second message sending device 135 is configured.

The terminal 110 is a terminal capable of transmitting a short message through a communication network. For example, the type of the terminal 110 may be a personal computer (PC), a personal digital assistant (PDA), a cellular phone, a personal communication service (PCS) phone, a hand-held PC, or a global system. for Mobile), WCDMA, CDMA-2000, and Mobile Broad and System (MBS) phones. Hereinafter, the terminal 110 will be described as an example. As described above, the terminal 110 may be equally applicable to all terminals capable of transmitting and / or receiving a short message / long text message.

The base station 115 receives location information of the terminal 110, registrant information, and a short message transmitted from the terminal 110. For example, the base station 115 may be configured to include a base station transmitter (BTS), a base station controller (BSC), and a repeater (not shown). have.

The base station transmitter is arranged in units of cells and performs a function of transmitting a short message requested from the terminal 110 to the exchange via the base station controller. In addition, the base station transmitter detects the position of the terminal 110 existing in the cell area under the control of the base station transmitter and performs location registration.

The base station transmitter receives location information of the base station transmitter from a global positioning system (GPS). The base station transmitter transmits the location information to the terminal 110 using the system parameter message of the forward link call channel. The terminal 110 may register new location information by calculating the location of the terminal 110 using the location information of the base station transmitter of the cell to which the terminal 110 belongs. Location registration is a process of informing the switch 120 of the location, status, identifier, slot period, and other characteristics of the terminal 110 through the base station transmitter, when the base station transmitter attempts to set up an incoming call to the terminal 110. It is possible to effectively call the terminal 110. Such location registration is performed when the terminal 110 is powered on or off, the terminal 110 moves the exchange period, or the parameter of the terminal 110 is changed.

The base station controller performs various functions required for radio call processing such as handoff while controlling and managing a plurality of base stations. The base station controller also transmits subscriber information of the location registered terminal to the exchange.

The base station controller performs a function of delivering a short message transmitted from the terminal 110 through the base station transmitter to the exchange. In addition, the base station controller performs a function of transmitting a short message transmitted through the counterpart terminal received from the exchange 120 to the terminal 110.

The switch 120 has a control function and an interworking function with a public telephone network and another network switch so that the wireless base stations can be efficiently operated. That is, the exchange 120 transmits and stores the first type message received through the base station 115 to the first message sending device 130. In addition, the exchange 120 transmits and stores the second type message received through the base station 115 to the second message sending device 135. In addition, the exchange 120 includes a function of collecting charging data on the use of the communication service of the terminal 110.

The home location register 125 is a database that stores service profiles related to subscriber information of the user of the terminal 110. The home location register 125 has information on a subscriber's phone number of the terminal 110, a mobile identification number (MIN), an electronic serial number (ESN), and a service type. That is, the home location register 125 stores all the subscriber information including the information of the base station 115 and the exchange 120 where the terminal 110 is located.

The first message sending device 130 is connected to the exchange 120 to perform a function of sending a message to the mobile communication service subscribers. In order to facilitate understanding and explanation, in the present specification, the first message sending device 130 is assumed to be a short message service center (SMSC).

The first message sending device 130 receives a request for transmission of a first type message including a phone number (ie, called number) of a counterpart terminal (ie, called terminal) from the terminal 110, and sends the first message to the called terminal. Sends a form message. In addition, when the first message sending device 130 fails to transmit the first type message to the called terminal, the first message sending device 130 temporarily transmits the first type message until a time designated by the terminal 110 or a state where the other terminal can be received. You can also save. For example, messages requested to be transmitted from the terminal 110 are temporarily stored in a message queue and then transmitted to the called terminal according to first-in, first-out (FIFO).

When the first message sending device 130 determines that the first type messages are in a transmission delay state (hereinafter, referred to as a 'transmission delay state') in the message sending device 130, the first message sending device 130 converts the first type message into a second format message. Convert to and transmit to the second message sending device 135. For example, the first message sending device 130 may convert the header into an HTTP header and convert the header into an HTTP header without changing the body of the first format message.

Accordingly, the first message sending device 130 may have an advantage of avoiding the first type message delay phenomenon to secure a recovery time due to the failure of the first message sending device 130. This will be described in more detail with reference to FIG. 4 below.

The second message sending device 135 is connected to the switchboard 120 and performs a function of sending a message to mobile communication service subscribers. In the present specification, for convenience of understanding and description, it will be described on the assumption that the message sending device 130 is a long message service center (LMSC).

The second message sending device 135 performs a function of transmitting a message received from the first message sending device 130 to the called terminal.

In the present specification, it is assumed that the first message sending device 130 is a short message center and the second message sending device 135 is a long message center. However, the first message sending device 130 is a long message center. The same may be applied to the case where the second message sending device 135 is a short message center.

In order to facilitate understanding and explanation, the first format message will be briefly described with reference to FIGS. 2 and 3. In the following description, the first format message is a short message and the second format message is a long message. The first format message is a long message, and the second format message may be a short message.

2 is a diagram illustrating a format of a short message according to an embodiment of the present invention, and FIG. 3 is a diagram illustrating a format of a long message according to an embodiment of the present invention.

Referring to FIG. 2, the short message includes a header area and a data area. The header area includes a length field including information on the length of the data area, a correlation number field used to match a response or error message associated with an invoke message, and a message, as shown in FIG. A message type field including information about the type is included. The data area of the short message contains the text of 80B.

As illustrated in FIG. 3, the palm print message includes a header part including information on a title, a content type, a body part including text information, and a media object part to which images, videos, and audio data are added. . As illustrated in FIG. 3, the long message includes attribute information about the message and content information of the message in an HTTP format.

Accordingly, when the first format message is a short message, the first message sending device 130 converts the header portion to the HTTP format without changing the contents of the first format message if the first format message is in a transmission delay state. Change to the second format message.

For example, suppose the first type message is "send a generous amount of scissors." The first message sending device 130 inserts application type information (m_application) in the header part and inserts the type by setting a second type message (eg, LMS) format. The first message sending device 130 may change and insert the calling number field into “m_Mobile: 0103010XXXX” and insert the called number field into “m_To: 0103020XXXX”. In addition, the first message sending device 130 may change the header part by setting attribute information not included in the first message format as blank or preset default information.

In the present specification, the description has been made on the assumption that the first message sending device 130 changes the first type message into a second type message. However, the second message sending device 135 is the first type from the first message sending device 130. The message may be received and changed into a second format message. Since the first message sending device 130 changes the first format message to the second format message, the second message sending apparatus 135 changes the first format message to the second format message. It will be omitted.

For another example, when the first format message is a palm print message, the first message sending device 130 extracts body information (ie, text information) from the first format message and changes the text message into a second format message. In addition, when the body information of the first format message exceeds the preset number of bytes (for example, 80B), the first message sending device 130 divides the body information into units of a predetermined number of bytes to divide the plurality of first information. You can also change to a two-format message.

4 is a block diagram illustrating an internal configuration of a message sending device according to an embodiment of the present invention. Hereinafter, assuming that the first message sending device 130 changes the first format message to the second format message, it will be described with emphasis. In addition, it will be described below with the assumption that the first format message is a short message and the second format message is a long message.

Referring to FIG. 4, the message sending device 130 according to the present invention includes a communication unit 410, an analyzer 420, and a converter 430.

The communication unit 410 transmits and receives various data through a communication network. For example, the communication unit 410 receives a first format message composed of at least one of a text and an image and loads the message in a message queue. Here, the message queue is a storage area in which first type messages waiting to be transmitted are temporarily stored. The first format messages stored in the message queue are transmitted in a first-in, first-out (FIFO) manner.

The analysis unit 420 may include the number of first type messages waiting to be transmitted in the message queue for a predetermined time (hereinafter referred to as the number of waiting for transmissions for convenience of understanding and explanation) and the first sent messages. It determines whether the message sending device 130 is in the transmission delay state by using the number of formal messages (hereinafter referred to as 'number of transmissions' for convenience of understanding and explanation).

For example, the analysis unit 420 calculates the number of transmission waits and the number of transmissions loaded in the message queue for a predetermined time, and calculates the difference between the number of transmission waits and the number of transmissions and determines whether or not it is below a preset threshold. . If the difference is less than or equal to the threshold value, the analyzer 420 may determine that the first message sending device 130 is in a transmission delay state.

When the first message sending device 130 is recognized as a transmission delay state, the analyzer 420 generates a warning indicator and transmits the warning information to the authentication center through the communication unit 410. Accordingly, the authentication center performs authentication on the first format message according to the transmission request of the terminal 110, inserts delay information into the header of the first format message, and transmits the delay information to the first message sending device 130. When the delay message is included in the header of the first format message, the first message transmission apparatus 130 converts the first format message into a second format message and transmits the second format message transmission apparatus through the communication unit 410. And transmit to 135.

When the first message sending device 130 is in a transmission delay state, the conversion unit 430 converts the first type message into a first type message according to a predetermined message standard and transmits the first type message to the second message sending device 135.

For example, if the first message sending device 130 is in a transmission delay state, the conversion unit 430 does not change the body of the short message and changes the header part to correspond to the preset second format message standard. Change to HTTP format. The conversion unit 430 transmits the changed second format message to the second message sending device 135. As such, when the first message sending device 130 is in a transmission delay state, the first message sending device 130 changes the first type message into a second type message and transmits the message to the second message sending device 135. There is an advantage that can prevent the delay of the short message.

5 is a diagram illustrating a configuration of a message sending system according to another embodiment of the present invention. Hereinafter, the description of the same components as those described in FIG. 1 will be omitted.

As illustrated in FIG. 5, the first message sending device 530 includes a message sending control device 531 and one or more message distribution devices 532.

The message dispatch control device 531 may classify the first type message by a specific number and region and transmit the message to the corresponding message distribution device 532.

The message distribution device 532 temporarily stores a first type of message corresponding to a predetermined specific number and a specific region in a message queue, and then sends the message to the destination terminal according to priority.

If the message distribution device of any one of the plurality of message distribution devices 532 is in the transmission delay state after the first message sending device 530 monitors each message transmission status of each message distribution device 532, the corresponding message is sent. Change the first formatted messages sent through the distribution device into second formatted messages.

In another example, each message distribution device 532 monitors the transmission status of each message distribution device, and when each message distribution device is set to a transmission delay state, information indicating that the transmission delay state is in the following description (hereinafter, the description and explanation will be described. For convenience, it may be called 'delay information' and may be generated and transmitted to the first message sending device 530. Accordingly, the first message sending device 530 may change the message to be sent through the corresponding message distribution device into a second type message and transmit the message to the second message sending device.

In FIG. 5, only the first message sending device 530 includes a plurality of message distribution devices, but the second message sending device 135 also uses the plurality of message distribution devices in the same manner as the first message sending device 530. Of course, it can include.

6 is a flowchart illustrating a method of sending a message according to a transmission delay in a message sending system according to an embodiment of the present invention. Hereinafter, assuming that a plurality of messages requested to be transmitted from the terminal 110 are accumulated in the first message sending device, the following operations will be described.

In operation 610, the first message sending device 130 determines whether the first message sending device is in a transmission delay state.

For example, the first message sending device 130 calculates the number of waiting to be sent and the number of waiting to be sent to the message queue of the first message sending device 130, respectively. As described above, the message queue is a storage area in which first type messages requested to be transmitted from the terminal 110 are temporarily stored. The first message sending device 130 calculates a difference value between the calculated waiting player and the number of sent items, and determines whether the calculated difference value is equal to or less than a preset threshold value. If the difference is less than or equal to the threshold, the first message sending device 130 sets the first message sending device 130 to a transmission delay state.

For another example, the first message sending device 130 may calculate a waiting time for each item, and may set the first message sending device 130 to a transmission delay state when the sending waiting time exceeds a preset reference time. .

If it is in the transmission delay state, the first message sending device 130 changes the first format message to the second format message in step 615.

For example, if the first format message is a short message, the first message sending device 130 may change the header portion into a HTTP format header and change the header portion to a second format message without changing the body of the first format message. have. Since this is the same as described with reference to FIGS. 2 and 3, redundant descriptions will be omitted.

In addition, if the first format message is a long message, the first message sending device 130 extracts the text of the body from the first format message, and extracts the calling number and the called number from the header portion. The first message sending device may change the message into a second format message using the extracted text. As described above, when the extracted text exceeds 80B, the first message sending device 130 may generate and transmit a plurality of second format messages by dividing the text in units of 80B.

In operation 620, the first message sending device 130 transmits the changed second type message to the second message sending device 135. Accordingly, the second message sending device 135 sends the second type message to the called terminal.

However, if it is not the transmission delay state, in step 620, the first message sending device 130 sends the first type message to the called terminal according to the conventional method.

7 is a view showing a schematic configuration of a message sending system according to another embodiment of the present invention. Hereinafter, only portions different from those of FIG. 1 will be described.

The exchange 720 requests authentication for the first type message requested to be transmitted, and obtains authentication information about the authentication result from the authentication server 725. The exchange 720 checks whether the delay information is inserted in the obtained authentication information, and if the delay information is inserted, inserts the delay information into the first format message and transmits the delay information to the first message sending device 730. . In more detail, the exchange 720 may insert the delay information into the header portion of the first format message and transmit the delay information to the first message sending device 730.

The first message sending device 730 monitors the message queue and, if the messages are in the transmission delay state, generates the delay information and transmits the delay information to the authentication server 725.

In addition, when the first message sending device 730 analyzes the first format message received from the switchboard 720 and includes delay information, the first message sending device 730 does not insert the first format message into the message queue as a second format message. The message is converted and transmitted to the second message sending device 735. For another example, when the first type message includes delay information in the first type message, the first message sending device 730 may transmit the first type message to the second message sending device 735 without converting the first type message into a second type message. It may be. Since the first message sending device 730 monitors the message queue and determines whether the message is in a transmission delay state, the description thereof will be omitted.

In addition, when the message queue is released from the transmission delay state, the first message sending device 730 generates delay release information and transmits the delay release information to the authentication center 725. After receiving the delay release information, the authentication center 725 transmits the first type message requested for authentication without inserting the delay information into the authentication information.

The second message sending device 735 performs a function of sending the second type message received from the first message sending device 730 to the called terminal through the communication network. For another example, when the second message sending device 735 receives the first type message including the delay information from the first message sending device 735, the second message sending device 735 converts the first type message into a second type message and sends the message to the called terminal. Can also be sent.

When the authentication information is received from the first message sending device 730, the authentication server 725 recognizes that the first message sending device 730 is in a transmission delay state. Accordingly, when authentication of the first type message is requested from the exchange 720 after the delay information is received, the authentication server 725 performs authentication and inserts the delay information into the authentication information to send the first message. 730 may be sent. For another example, when authentication server 725 receives an authentication request that includes a first format message from exchange 720, authentication server 725 performs authentication on the first format message and then the first format. The delay information may be inserted into the header portion of the message and transmitted to the exchange 720.

In addition, when the delay release information is received from the first message sending device 730, the authentication server 725 recognizes that the transmission state of the first message sending device 730 is good, and then the first form requested for authentication thereafter. For the message, authentication information without delay information is transmitted. That is, the authentication server 725 may perform authentication and transmit authentication information in the same manner as in the related art.

As such, by controlling the sending by inserting the delay information into the first type of message, there is an advantage that the billing can be prevented from being doubled in the system.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the invention may be varied and varied without departing from the scope of the invention.
