In addition, the short message processing system and method according to the present invention, it is possible to prevent an overload or down phenomenon of the short message service center due to the congestion of throughput of the short message.

Hereinafter, a short message processing system according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

1 is an overall configuration of a short message processing system according to an embodiment of the present invention.

Referring to FIG. 1, a short message processing system according to an embodiment of the present invention includes a calling terminal (110, 120, 130), a message relay device (210, 220, 230), a short message service center (SMSC). Center 300, a short message buffering server (SMS Buffering Server) 400, and the destination terminal 510. In addition, according to the type of the originating terminal (110, 120, 130) and the terminating terminal 510, the base station (111, 511) and the switch (210, 520), VSMS server (Vertical SMS Server) 220, HSMS server ( Horizontal SMS Server) 230 may be additionally included.

Calling terminal (110, 120, 130) (hereinafter referred to as 100 if no classification is necessary) is a device for generating and displaying a short message for the called number by the caller operation, the company's mobile phone (110), computer The terminal 120, a third-party mobile phone 130, personal digital assistants (PDAs), and the like are all types of terminals having a built-in communication function for transmitting a short message by itself.

The originating exchange 210, the VSMS server 220, and the HSMS server 230 are message relay devices for interworking the originating terminal 100 and the short message buffering server 400 when transmitting and receiving a short message.

The message relay apparatuses 210, 220, and 230 (hereinafter, collectively referred to as No. 200 when no distinction between the types is necessary) relay the transmission and reception of the short message in association with the calling terminal 100 and the short message service center 300.

The message relay device 200 receives a short message created by the caller from the calling terminal 100, a called number of the called terminal 510 to send a short message, and a calling number of the calling terminal 100, and includes such data. The short message transmission request is generated and transmitted to the short message buffering server 400.

The calling number and the called number are numbers used for identification of a terminal, such as a mobile identification number (MIN), and are numbers used for transmitting and receiving a short message.

The calling number is a reply number of the short message, which may be the calling number of the calling terminal 100, or when the caller composes the short message to be sent to the called terminal 510, inputs it arbitrarily to receive a reply to the short message to be sent. It may be a phone number. The calling number is sent to the called terminal 510 with a short message.

The type of the message relay device 200 used may vary depending on the type of the calling terminal 100.

For example, when the mobile phone 110 of the company is used as the calling terminal 100, the calling terminal 210 interworking with the calling base station 111 and the calling exchange 210, the calling switch 210 coupled with the calling base station 111. ) Is used as the message relay device 200.

The originating base station 111 is a network termination device connected to the calling terminal 100 in a wireless manner, and receives a short message from the calling terminal 100 of its mobile phone 110 type, and receives the received short message from the calling number and the called party. It transmits to the calling exchange 210 with the number.

The originating exchange 210 performs subscriber's incoming and outgoing call processing, location registration procedure and handoff procedure processing, interworking function with other operator's network, etc. and generates corresponding short message transmitted from the originating base station 111. The short message transmission request is transmitted to the short message buffering server 400.

When the computer 120 is used as the calling terminal 100 and the short message is transmitted through the web, the VSMS server 220 operates as the message relay device 200 and the short message is transmitted to the VSMS server 220. The short message transmission request is transmitted to the short message service center 300 to which the called terminal 510 belongs.

When the third-party mobile phone 130 that is linked to the network of the other operator is used as the calling terminal 100, the HSMS server 230 operates as the message relay device 200 to send a short message to the HSMS server 230 Thereafter, the short message transmission request is transmitted to the short message service center 300 to which the called terminal 510 belongs.

The VSMS server 220 and the HSMS server 230 perform an interworking function between the calling terminal 100 of the computer 120 or the third-party mobile phone 130 type and the short message service center 300 for transmitting and receiving the short message.

As such, the calling terminal 100 is combined with the short message service center 300 and the short message buffering server 400 through the message relay device 200 suitable for the path according to the type, and the short message to the called terminal 510. Send.

In addition, after the message relay device 200 transmits the short message transmission request to the short message service center 300, if the short message transmission request is blocked due to an overload state of the short message service center 300, the short message service center The short message transmission request blocked from the 300 is transmitted to the short message buffering server 400 again.

The short message service center 300 blocks a short message transmission request corresponding to the short message transmitted from the calling terminal 100 when the overload state enters. When the overload state is released, the short message transmission request, which has been blocked due to the overload state, is re-received from the short message buffering server 400 to provide a short message to the called party number.

Specifically, the short message service center 300 always checks whether there is an overload condition, and enters an overload state when a large amount of short message transmission requests exceeding its capacity are introduced through the message relay device 200. Short message service center 300 has entered the overload state to block the service connection for the new short message introduced after the overload state entered for stable operation. When the overload state is released, the short message service center 300 allows the introduction of a new short message coming through the message relay device 200 to perform a short message transmission service normally.

The short message buffering server 400 is responsible for temporarily storing and retransmitting a short message transmission request that flows after an overload of the short message service center 300 occurs. That is, the short message transmission request is temporarily stored, which is blocked due to the overload of the short message service center 300, and the short message service request is stored when the overload state of the short message service center 300 is released. Send back to 300).

Here, the short message transmission request blocked by the overload state of the short message service center 300 is transmitted from the message relay device 200 that interworks with the calling terminal 100 that transmits the short message, and the short message buffering server ( 400).

That is, the message relay device 200 transmits the short message transmission request for the short message generated from the calling terminal 100 to the short message service center 300, and then, due to the overload state of the short message service center 300. If the short message transmission request is blocked, the short message is retransmitted to the short message buffering server 400 and temporarily stored.

If the short message transmission is congested at a specific time, if the service connection to the new short message is blocked due to the overload of the short message service center 300, the short message may be lost without being normally transmitted, so that the short message is buffered. This phenomenon is prevented through the server 400.

The called terminal 510 is a device for receiving a short message transmitted from the calling terminal 100. The receiving terminal 510 is combined with the short message service center 300 through the called exchange 520 and the called base station 511, and performs a short message service. The center 300 receives a short message about its called number.

The destination exchange 520 performs the subscriber's incoming and outgoing call processing, the location registration procedure, and the like, similar to the originating exchange 210, and receives the short message received from the short message service center 300 through the destination base station 511. The call is sent to the called terminal 510.

The called base station 511 is a network termination device wirelessly connected to the called terminal 510 and transmits a short message transmitted from the called exchange 520 to the called terminal 510 corresponding to the called number.

Although the receiving terminal 510 is illustrated in FIG. 1 as a mobile phone type, any device having a built-in communication function for receiving a short message from a short message service center 300 such as a personal mobile terminal or a computer may be used without any limitation. It may be used as the called terminal 510.

As described above, the short message processing system as shown in FIG. 1 stores the short messages that may be lost due to the overload control when the short message service center 300 enters the overload state in the short message buffering server 400, and then releases the overload. Resend to the called party.

Through this configuration, it is possible to prevent a short message transmission failure even when a large number of short messages are sent. As a result, the short message transmission request is continuously accommodated without blocking the service even in an overload state of the short message service center 300, thereby eliminating time constraints on the use of the short message and increasing service quality and user satisfaction.

FIG. 2 is an internal configuration diagram of some of the devices shown in FIG. 1, and illustrates a detailed configuration included in the short message service center 300 and the short message buffering server 400.

Referring to FIG. 2, the short message service center 300 includes an inspection module 310, an attribute module 320, a service blocking module 330, a notification module 340, and a message control module 350.

The inspection module 310 provided in the short message service center 300 continuously checks whether the throughput of the short messages requested to be transmitted from the message relay device 200 exceeds its capacity.

The attribute module 320 sets an overload state when the throughput of the short messages requested to be transmitted exceeds its capacity according to the inspection result of the inspection module 310, and releases the overload state if it does not exceed its capacity.

When the attribute module 320 enters an overloaded state, the service blocking module 330 blocks all incoming short message transmission requests. The short message transmission request includes a short message, a calling number, and a called number created by the sender.

When the overload state of the attribute module 320 is released, the notification module 340 transmits an overload release signal to the short message buffering server 400.

The message control module 350 re-receives the short message transmission request that was temporarily stored from the short message buffering server 400 in response to the overload release signal, and corresponds to the short message included in the re-received short message transmission request. Provide the called number.

Meanwhile, the short message buffering server 400 includes a storage module 410 and a message processing module 420.

The storage module 410 is transmitted from the message relay device 200 to the short message service center 300, and the short message service is blocked from the short message service center 300 due to the overload occurrence of the short message service center 300. The request is received from the message relay device 200 and temporarily stored.

When the overload release signal is received from the short message service center 300 when the overload state of the short message service center 300 is released, the message processing module 420 is blocked from the short message service center 300 and stored in response thereto. The module 410 sends the temporarily stored short message transmission request back to the short message service center 300.

Hereinafter, a short message processing method according to a preferred embodiment of the present invention will be described in detail with reference to FIG. 3.

3 is an overall data flow diagram of a short message processing method according to an embodiment of the present invention.

First, in step S110, the caller sends a short message using the calling terminal 100. The calling terminal 100 and the message relay device 200 generate a short message transmission request for the called terminal 510 according to the short message created by the caller, and generate the short message transmission request from the short message service center ( 300).

Here, the calling terminal 100 may be used as its own mobile phone 110, computer 120, third-party mobile phone 130, and the like, as the message relay device 200, the call exchanger 210, VSMS server 220, HSMS Server 230 may be used.

When the company's mobile phone 110 is used as the calling terminal 100, the short message transmission request is sent to the short message service center 300 through the calling base station 111 and the calling exchange 210 as shown in FIG. Is sent.

When the computer 120 is used as the calling terminal 100 and the short message is transmitted through the web, the short message is sent to the short message service center 300 to which the called party belongs after the VSMS server 220 receives the short message. Send the transfer request.

When the third-party mobile phone 130 is used as the calling terminal 100 and the called terminal 510 corresponding to the called number belongs to the own network, the HSMS server 230 receives the short message and then the called party belongs. The short message service center 300 transmits a short message transmission request.

Next, in step S120, the transmission request for the new short message flowing into the short message service center 300 is blocked due to the overload of the short message service center 300.

The step S120 may be subdivided into steps S121 and S123.

The short message service center 300 continuously checks whether the throughput of the short messages requested to be transmitted in step S121 exceeds its capacity, and enters an overloaded state when the short message transmission amount exceeds its capacity.

In the normal state, not the overload state, the short message service center 300 proceeds to step S123 normal processing of the received short message and delivers the short message to the called terminal 510 of the called party. In the case of entering the overload state, the short message service center 300 proceeds to step S122.

In step S122, the short message service center 300 blocks the transmission request for a new short message flowing from the message relay device 200 after entering the overload state. That is, the short message transmission request sent from the message relay device 200 is blocked due to the overload state of the short message service center 300.

Next, in step S130, the short message transmission request blocked from the short message service center 300 due to the overload is stored in the short message buffering server 400 instead of the short message service center 300 for a while. Then, the short message transmission request blocked from the short message service center 300 attempts to retransmit through the short message buffering server 400.

The outgoing exchange 210, the VSMS server 220, and the HSMS server 230, which operate as the message relay device 200, transmit the short message transmission request blocked by the overload control of the short message service center 300 to the short message buffering server. Temporarily store at 400.

Operation S130 may be subdivided into operations S131 and S132.

In step S131, the message relay device 200 transmits the short message transmission request blocked from the short message service center 300 to the short message buffering server 400 again.

In step S132, the short message buffering server 400 receives and temporarily stores the short message transmission request blocked by the overload of the short message service center 300 from the message relay device 200.

Next, in step S140, the overload state of the short message service center 300 is released, and an unprocessed short message due to the overload is transmitted to the called terminal 510.

Step S140 may be subdivided into steps S141 to S144.

In step S141, the short message service center 300 determines whether an overload state or an overload release state is performed by checking whether the throughput of the short message requests transmitted exceeds its capacity as in step S121.

When the overload state of the short message service center 300 is released, the short message service center 300 proceeds to step S142 to notify the short message buffering server 400 of the release of the overload state, the short message buffering server 400 To transmit an overload release signal.

In step S143, the short message buffering server 400 is blocked due to the overload of the short message service center 300 and transmits the transmission request for the short message that was temporarily stored back to the short message service center (300).

In step S144, the short message service center 300 receives a short message transmission request from the short message buffering server 400, and transmits the short message to the destination terminal 510 corresponding thereto.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof.
