Abstract

PURPOSE: A system for preventing the loss of an SMS message is provided to prevent loss of a message between an SMSC(Service Management System Center) and an SMS(Short Message Service) server by applying a memory queue to disassemble a system resource when short messages are congested. CONSTITUTION: An SMSC includes an SMSC operating DB(310), a memory queue(320) and a process(330). The SMSC operating DB(310) stores short message information. The memory queue(330) divides a message exceeding a memory buffer capacity of the SMSC operating DB(310) and stores the divided parts of the message. The process(330) checks the size of the message and the number of the parts of the message to determine whether they reach a maximum limit value. An SMS server(400) manages a message transmitted for a TCP/IP communication with the SMSC(300).

Description

SMS message loss preventing system

The present invention relates to a system for preventing the loss of SMS messages. More specifically, the present invention relates to a system for preventing the loss of SMS messages caused by congestion between SMSCs and SMS servers in a mobile communication system.

With the rapid development of mobile terminal technology and the increase of mobile subscribers, mobile communication service providers are providing various additional services to meet the needs of mobile subscribers and attract more subscribers.

Such an additional service is a short message service (SMS). SMS is a service that allows the communication terminal to send and receive a sentence of a predetermined capacity. SMS has the same features as two-way radio calling, which allows for simple text reception, voice mailbox notification, and text delivery to meet customer needs.

In general, users using a mobile communication terminal have been able to send or receive necessary messages to a desired party through the use of an SMS function additionally implemented in the terminal. The SMS function must be supported by the digital portable terminal system to which the terminal is subscribed, and at the same time, the terminal itself can realize the function of inputting, editing, and sending a required message.

1 is a block diagram illustrating a message processing process between an SMSC and an SMS server according to the prior art.

Referring to Figure 1, SMSC operation DB (11) for storing the short message information, UDP (User Datagram Protocol; 12) of the message transmission method in the SMSC, dedicated to communication with the SMS server 20 and serves to deliver a short message An SMSC 10 equipped with a process 13; SMS server 20 for managing the message transmitted through the TCP / IP communication with the SMSC (10).

The message processing system between the SMSC and the SMS server having such a configuration uses the UDP method as a message transmission method within the SMSC when transmitting a message from the SMSC to the SMS server, thereby limiting the memory buffer capacity by limiting the buffer size per 100 TCP / IP connections. There is a high possibility that the management function (message storage, etc.) is missing after the message is transmitted, resulting in the possibility of the message being lost.

In addition, when a message is lost from the SMSC to the SMS server, a non-response phenomenon occurs at the SMS server due to the absence of a reprocessing process.

The present invention is to solve the above problems, the present invention is to prevent the loss of messages between the SMSC and the SMS server by applying a message queue of the function of storing and distributing the short message in the mobile communication system when congested There is a purpose.

As the technical idea for achieving the above object of the present invention

In the message loss prevention system between SMSC and SMS in mobile communication network,

An SMSC operation DB for storing short message information; A memory queue for dividing and storing a message exceeding a memory buffer capacity of the SMSC operation DB; An SMSC including a process of checking the size and number of messages in the memory queue to determine whether a maximum limit has been reached;

Provided is a system for preventing the loss of an SMS message comprising an SMS server for managing a message transmitted through TCP / IP communication with the SMSC.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.

2 is a block diagram illustrating a message processing process between an SMSC and an SMS server according to the present invention.

2, an SMSC operation DB 310 for storing short message information; A memory queue 330 for dividing and storing a message exceeding a memory buffer capacity of the SMSC operation DB 320; An SMSC (300) having a process (330) for determining whether a maximum limit has been reached by checking the size and number of messages in the memory queue (330); SMS server 400 for managing the message transmitted through the TCP / IP communication with the SMSC (300).

Here, referring to the difference in the message processing process from the SMSC 300 to the SMS server 400, the buffer capacity is exceeded by using the divided memory queue 320 of the memory type instead of the UDP 120 implemented in the conventional file type. This can prevent the loss of messages that occur.

That is, the conventional UDP 120 is OS dependent, so it takes a long time to boot the OS due to OS booting when the size is changed, there is no management function after message transfer, and the buffer size per TCP / IP connection is limited to 100. The possibility of exceeding the buffer capacity turned on, resulting in message loss.

However, in the present invention, by applying the memory queue 320 in place of the UDP 120, the management function is excellent with the alarm function when the memory queue is full, and can be processed in a short time by restarting the application, the application is used in the form of a divided memory queue You can manage this memory usage. In addition, the memory buffer size per TCP / IP connection is allocated to 1000, allowing expansion according to memory margin.

This can be managed by the memory queue 320 having the message storage and partitioning function of the SMSC 300 to manage the message storage after the message transmission, thereby preventing the loss of the message.

In addition, when the non-response between the memory queue 320 and the SMS server 400, the message is retransmitted up to three times every hour, thereby preventing the loss of the message.

As described above, according to the SMS message loss prevention system in the mobile communication network according to the present invention, by applying a memory queue instead of the conventional UDP, it is possible to prevent the message loss between the SMSC and SMS server by decomposing system resources during short message congestion. have.

This ensures the integrity of the message transmission between the SMSC and the SMS server can further increase the reliability of the short message service.
