The present invention relates to a short message service (SMS), and in particular, when a large amount of messages to be sent to a mobile terminal of a particular subscriber is stored in a DB (database) of a short message service center (SMSC) that processes a short message, data processing of the DB is performed. This is to solve the short message processing delay phenomenon by affecting the performance of the entire SMSC as it is delayed. Even if a short message is accumulated to a specific subscriber by changing the DB process in the SMSC, the short message processing delay is smooth. The present invention relates to a method of processing a short message when a call is congested to a specific subscriber that can process a short message.

Short Message Service (SMS) is a communication service that delivers limited-length text messages between various short message input devices and mobile terminals (MSs) or between mobile terminals and mobile terminals regardless of whether a mobile subscriber is busy. to be.

SMS can send texts of about 80 bytes (80 characters in English) to the LCD screen of mobile terminals. SMS can control access channels and paging channels as well as traffic channels. Short messages can be delivered in the form of a database character, enabling service regardless of the operating status of the mobile terminal.

SMS can provide a variety of services ranging from simple text messaging between individuals to various marketing means such as information delivery using customer DB to create new services. Is exploding.

In order to provide an SMS between the mobile terminal and the mobile terminal, or between various short message input devices and the mobile terminal, the SMS network configuration as shown in FIG. 1 is provided. As shown in FIG. 1, the SMS system 30 for providing an SMS service may be briefly configured as an SMSC 31 and a SMSS 33.

The SMSC 31 manages the DB of the SMS subscriber, provides an interface between the SMSS 33 and various IPs (external clients), and interworks with various information providers of a content provider (CP) network.

The SMSS 33 provides the SMS to PC communication, the Internet, and the bank through a living information server and also provides SMS to external clients having a corporate IP, etc., and VSMSS (33b, Vertical SMSS) and other companies (KTF, LGT). ) Can be divided into HSMSS (33a, Horizontal SMSS) that provides SMS interworking.

The SMSC 31 is connected to the SMSS 33 via TCP / IP.

SMSC (31) is a kind of store and forward message switch (Store and Forward Message Switch), and stores a short message transmitted to the called terminal 20 that cannot be received at any moment until the terminal can receive ( Store) forwards and forwards to the called terminal.

The SMSC 31 is connected to the Home Location Register (HLR) 40 and the Mobile Service Center (MSC) 23 to determine the location of the called terminal 20 and to deliver a short message.

SMSC (31) can send and receive numbers and letters in both directions between a variety of text delivery system (PC communication system, Internet server system, etc.) and mobile terminals using a mobile communication network, the mobile subscriber is a mobile terminal (generally a mobile phone) Etc.), a short message may be sent to another mobile terminal.

The SMSC 31 stores the short message received from the calling terminal 10 in an internal DB (queue, queue) according to the called subscriber number, and inquires the route to the HLR 40 to know the location information of the called terminal 20. do. Upon successful reception of the route information from the HLR 40, the SMSC 31 attempts to send a short message to the destination MSC 23, which is currently connected to the destination terminal 20.

If the short message is not properly transmitted because the terminal 20 is not connected, the SMS 31 periodically retransmits the short message. If necessary, after delivery of the short message, the SMSC 31 notifies the HLR 40 of the result of the delivery and updates the internal information table. The SMSC 31 receives the confirmation notification from the HLR 40 and the MSC 23 when it is connected to the called terminal 20.

The short message requested by the SMS subscriber is stored in the SMSC 31 until the time designated by the calling terminal 10 or the called terminal 20 reaches a state in which it can be received. The text transmitted to the called terminal 20 by the SMSC 31 is deleted after acknowledgment of the called terminal 20, and a short message which is not delivered after a predetermined time elapses or until a valid time designated by the subscriber is deleted. The maximum number of characters that can be transmitted per subscriber is determined by the capacity of the SMSC 31.

Short messages come from SMS subscriber's mobile terminal or from several other SMSC clients such as CP 50 (Operator, Batch, E-mail, Voice Mail, or Customized Client). If stored in the SMSC 31 sends a confirmation notification to the sender.

When multiple originating terminals send a message to a specific called number, one or more short messages are accumulated in a queue of the internal DB of the SMSC 31 in the order required to be delivered to the same same number.

If there is a high priority short message, it is delivered before the normal short message. The queue has a normal queue and a priority queue, so if there are a lot of high priority short messages, they are also stacked in the order of priority.

All short messages that need to be sent are processed in order until they are all sent or discarded in the DB for reasons such as storage time or delivery failure. The calling subscriber is notified of the result of the short message delivered through his mobile terminal 10.

When the SMSC 31 sends a short message to the SMSS 33, the SMSC 31 is configured to send a short message after receiving a response to the short message for each called number. However, if a short message is concentrated on a particular subscriber, the processing is delayed.

As shown in FIG. 2A, when a short message is sent from a plurality of terminals to a specific called number according to the related art, a plurality of client terminals 10 may send a short message to the CP network 50. For example, location tracking for taxis can be done via SMS.

As shown in FIG. 2A, location information messages sent from a plurality of taxis are accumulated by being assigned to a number of a specific server of the CP network 50 providing the same. Therefore, when a large number of short messages are accumulated in a specific called number, only one SME (Short Message Entity, a key required for processing messages) exists, which causes a problem in that the processing speed becomes very slow.

In addition, FIG. 3A illustrates a method of processing a short message when a call is congested as a large amount of messages are sent from a specific CP to a specific subscriber according to the prior art. As shown in FIG. Since the short messages received in (31) are exchanged between the calling number and the called number in the process of being stored in the DB, the received data for many short messages sent by a specific subscriber is accumulated in one number.

The DB of the SMSC 31 is a MMDB (Main Memory DB), which is a DB that temporarily stores the short message introduced through the short message provider in the SMSC 31 to the customer to manage the delivery of the short message to the customer. The case where the space for storing the called number is stored through the mobile terminal 10 and the case where the short message is stored through the CP 50 is opposite to each other.

Therefore, the short messages received by the SMSC 31 from the CP 50 via the SMSS 33 are transmitted to the correct destination when the short message is sent to the correct destination when the calling number and the called number are interchanged in the process of storing in the DB. As shown in 3a, when a large number of messages are sent to a plurality of subscriber stations in a specific CP, many short messages sent by a specific subscriber are accumulated in one number (phone number of a specific CP).

Accordingly, a lot of short messages are accumulated in a specific calling number, and there is a problem that the processing speed becomes very slow because there is only one receiving SME.

Accordingly, an object of the present invention for solving the above problems is to short message at the time of call congestion to a specific subscriber to distribute the message processing keys so that a large amount of messages to be sent to a specific subscriber in SMSC does not delay message processing To provide a treatment method.

In addition, another object of the present invention is to provide a method for processing a short message when a call is congested to a specific subscriber so that the received message processing keys can be distributed and processed so that a large amount of messages received from the specific subscriber are accumulated so that message processing is not delayed. .

In order to achieve the above object, the present invention provides a short message processing method of SMSC (Short Message Service Center);

When a plurality of short messages received from a plurality of mobile terminals in the SMSC are stored in a queue corresponding to the specific called number to be transmitted to a specific called number, a short message assigned to the specific called number Generate one or more short message processing means assigned to the specific called number by changing a TON (Type Of Number) and a Number Plan Indicator (NPI) of the processing means, and generating the one or more short message processing means in the generated one or more short message processing means. The present invention provides a method for processing a short message upon call congestion to a specific subscriber, characterized in that each message is distributed and processed to be sent to the specific called number.

In this case, in the method of processing a short message at the time of call burst to a specific subscriber according to the present invention, the number of generated short message processing means is generated at a specific ratio corresponding to the number of short messages stored in the queue.

In addition, in order to achieve the above object, the present invention provides a short message processing method of SMSC;

When a plurality of short messages are received from the specific calling number in the SMSC for transmission to the plurality of mobile terminals, the plurality of short messages are sent to the queues assigned to each of the plurality of short messages and the called number is directly assigned to the queues. Storing and transmitting the short message and the called number information of the short message stored in the queue assigned to the queues, respectively, and distributing the short messages to the changed called numbers, respectively. It provides a method for processing a short message when a call congestion to a particular subscriber characterized in that.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same components have the same reference numerals as much as possible even if they are displayed on different drawings. Detailed descriptions of well-known functions and configurations that are determined to unnecessarily obscure the subject matter of the present invention will be omitted.

Figure 2b is a diagram showing a method of processing a short message according to the present invention when a call is called to a specific called number in multiple terminals, Figure 3b is a diagram showing a method of processing a short message according to the present invention when a call congestion from a specific terminal to a particular subscriber .

In the case of receiving the short messages intended to be transmitted to a specific called number from a plurality of terminals in comparison with FIG. 2A, FIG. 2B will be described a method for relieving the delay of message processing due to call burst according to the present invention.

As shown in FIG. 2A, unlike the case where one SME 35 to process mobile messages (MO) accumulated corresponding to a specific called number 50 exists, the processing speed is very slow. As shown in the figure, when a certain number of short messages (MO) are accumulated in a queue corresponding to a specific called number of the SMSC 31, a plurality of SMEs 35 varying TON (Type Of Number) and NPI (Number Plan Indicator) values. Generate and distribute the stacked short messages (MO). Here, as illustrated in FIG. 2A, when more than 1000 short messages stacked in correspondence with a specific called number 50 are accumulated in the SME 35, a load is generated and a delay occurs in FIG. 2B. As shown, when about 500 or more short messages (MO) are accumulated in a queue corresponding to a specific called number of the SMSC 31 corresponding to the preferred embodiment of the present invention, TON (Type Of Number) and NPI (Number Plan Indicator) It is possible to create one or more SME 35 with different values.

In this case, TON is a value to set the destination address as an international type or a national type, NPI is a value to set the address system, and (TON, NPI) is a general message (1,1). ), The message (11, 11) and the premium message for the mobile terminal of the called subscriber using the wireless network provided by other mobile communication network providers (13, 13), etc. Create SMEs.

As shown in FIG. 2B, a plurality of SMEs 35 are generated at a specific ratio with respect to the number of received short messages for a plurality of short messages MO, and distributed in each SME 35 to increase processing speed and delay. It can solve the problem. Here, the specific ratio means 50% or more of the total limit that the SME 35 can process, and the number of the generated SME 35 means one or more.

Meanwhile, referring to FIG. 3B, the received message MT received by the SMSC 31 in order to send a large number of short messages (MT) in a specific CP 50 is used so that the short messages are not accumulated in one number. In the process of storing in (Main Memory DataBase), the received messages are stored as they are without changing the calling number and the called number.Then, when the received messages are taken out of the queue of DB, the calling number and called number are changed and sent.

Accordingly, as shown in FIG. 3A, since the received messages MT having the same origination number are not stored in the designated queue, a plurality of short messages MT received by one receiving SME 37 corresponding to the queue are not stored. By not storing the queue, the caller ID and the called party number are stored to be reversed when stored in the queue, so that the SME 35 distributes the short message according to different called numbers as shown in FIG. 3B. You can speed it up.

For this purpose, it is created by the ixdnif process (a process that monitors the TCP / IP connection status and establishes and restarts the SME connection), and interfaces with the SME using the Short Message Peer to Peer (SMPP). When sending MTs in the sending ixsmtcp process, the calling number and the called number are interchanged.

Therefore, a large number of messages received to be sent from one particular CP 50 to a plurality of subscribers are distributed according to a called number (actually recognized as a calling number) in a plurality of SMEs 35, and the correct called number when sent. By switching to and sending it, the processing time can be shortened and a short message service can be provided quickly.

As described above, the method of processing a short message when a call is congested to a specific subscriber according to the present invention includes a plurality of short messages that a plurality of terminals send to SMSC to a specific called number or a specific CP sends a large amount of short messages to a plurality of subscribers. If a short message is received, the short message processing speed can be increased by allowing the DB to shortly process the short messages.

On the other hand, in the detailed description of the present invention has been described with reference to specific embodiments, various modifications are possible without departing from the scope of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention has an effect of smoothly processing a large amount of messages to be transmitted to a specific subscriber by distributing and processing message processing keys in the SMSC.

In addition, the present invention is effective to smoothly process a large amount of messages received from a particular subscriber by adjusting the DB storage process in the SMSC.
