As shown in FIG. 1, when a communication terminal attempts a call connection request to another communication terminal under a communication service currently supported between communication terminals, the corresponding network management system makes a call between the communication terminal and a counterpart terminal requested to be connected. The connection is controlled to enable communication with each other (110). As described above, the call may be disconnected due to various communication obstacles such as bad weather, bad weather, terminal failure, or terminal battery discharge, such as mountainous areas, while the call is made between both communication terminals (120). Therefore, both communication terminal users can call again by removing the communication obstacle and retrying the call connection.

However, at this time, even if a call break occurs, the conventional communication terminal is not provided with the cause at all, and only the call connection is terminated. That is, the conventional network management system does not provide any information for disconnecting and preparing the call connection of the communication terminal when the call connection is difficult due to communication obstacles, so the users of the communication terminal clearly know the cause of the call disconnection. There is no way to deal with it except by simply retrying the call or attempting to make the call outside the shadowed area as per speculation. Accordingly, there is a need for a method of effectively enabling a user to solve a situation more effectively through a service informing a cause of disconnection of a call during a call.

When the call is disconnected during the call with the terminal 240, it is proposed to analyze the cause of the call disconnection so as to transmit a text message indicating the cause of the call disconnection to a communication terminal selected according to a predetermined method.

To this end, according to an embodiment of the present invention, the call disconnection cause notification server 230 determines whether a call disconnection occurring during a call between communication terminals 210 and 240 is normal or abnormal, and a corresponding cause for abnormal call disconnection. After the analysis, the code is extracted from the database (310 of FIG. 3) that stores and manages codes for cause of call disconnection. In addition, the message receiving party indicating the counterpart terminal 240 on the side of providing the cause of the abnormal call disconnection is determined according to the extracted corresponding code, and the determined message receiving party is informed of the cause of disconnection according to the extracted corresponding code. Allows sending in the form of a text message. As such, when the call connection between the communication terminals 210 and 240 is disconnected due to an abnormal communication obstacle, the cause of the call disconnection may be provided to the counterpart communication terminal providing the cause of the call disconnection in the form of a text message. There is an effect that enables the user of the communication terminal to easily identify and respond to the cause of the call disconnection.

When the mobile communication terminal 210 is in a call connection state with the counterpart terminal 240 and the call is disconnected due to a communication obstacle, the mobile communication terminal 210 or the counterpart terminal 240 may be in a predetermined condition. Accordingly, the cause of the call disconnection notification server 230 may receive the cause of the call disconnection analyzed. For example, if the call disconnection is caused by an abnormal cause, the other party's terminal providing the cause may receive the cause of the call disconnection in the form of a text message. In this case, the abnormal cause is intentionally determined by the user of the communication terminals 210 and 240 such that any one of the communication terminals 210 and 240 is located in a shadowed area and the call disconnection occurs. The call is disconnected even if the call is not interrupted.

The mobile communication network 220 refers to a communication network connecting a mobile communication terminal with a fixed point or between mobile communication terminals, and various mobile communication principles, such as a cellular mobile communication scheme, may be applied.

When the call disconnection between the mobile communication terminal 210 and the counterpart terminal 240 is disconnected, the call disconnection cause notification server 230 determines whether the disconnection during communication between the communication terminals is normal or abnormal. In addition, by analyzing the cause, if it is an abnormal call disconnection, extract the code from the database 320 for storing and managing the code for each call disconnection cause to determine the cause of the abnormal call disconnection according to the extracted corresponding code The cause is transmitted to the counterpart terminal of the providing party in the form of a text message. Accordingly, the target terminal receiving the cause of disconnection can know through the text message what cause the call is abnormally terminated, and can follow up accordingly.

In addition, a WAP (Wireless Application Protocol) server that provides a WAP page form through the mobile communication network 220 may be used as the call disconnection cause notification server 230. The swap server is a server that conforms to international standards that allow a communication terminal to communicate with the Internet or perform an application with another computer according to a wireless application communication protocol. The swap server may define an application program interface (API) to mount various applications in a gateway. . In addition, the call disconnection cause notification server 230 may use a web server that provides the call disconnection cause in the form of a web page through a wired or wireless Internet as well as a swap server.

The counterpart terminal 240 is connected according to a call request of the mobile communication terminal 210, and similar to the mobile communication terminal 210, when a call is disconnected due to the abnormal disconnection cause, a character generated according to a predetermined condition. You can receive a message. More detailed operations of the mobile communication terminal 210 and the counterpart terminal 240 will be described later with reference to FIG. 3.

It is interpreted as a concept that collectively includes a terminal capable of performing a certain operation by mounting a microprocessor capable of performing a multimedia playback function.

3 is a block diagram illustrating an internal structure of the call disconnection cause notification server 230 of FIG. 2.

As shown in FIG. 3, the call disconnection cause notification server 230 includes a control unit 310, a database 320, a disconnection cause checking and analyzing unit 330, a message receiving target selector 340, and a message transmitting unit. And 350.

The controller 310 generally controls each component of the call disconnection cause notification server 230.

The database 320 stores and manages codes for cause of disconnection. That is, the cause of the call disconnection can be coded and code names for each code can be managed, so that the code name can be retrieved to the corresponding communication terminals 210 and 240 according to a predetermined rule to transmit related information. To be. The corresponding code may be a combination of numbers, letters, and the like corresponding to the causes of disconnection. In addition, the coded disconnection causes may be stored in an auxiliary storage device such as a memory, a hard disk drive, a USB memory, or the like. For example, the cause of call disconnection, which may occur during a call between both communication terminals, is classified into a discharge of a battery, a failure of a terminal, a network failure, and the like. Can be.

The disconnection cause checking and analyzing unit 330 determines whether a call disconnection occurring during a call between communication terminals is normal or abnormal, analyzes the cause of the abnormal call disconnection, and extracts a corresponding code from the database 320. . That is, the disconnection cause check and analysis unit 330 analyzes the cause (error code, etc.) for disconnection of the call and performs a reason code logging check to extract the corresponding code from the database 320.

The normal disconnection may be caused by intentionally disconnecting a call by pressing a call termination button on the mobile communication terminal 210 or the counterpart terminal 240. In addition, other call disconnection operations (eg, covering a folder, etc.) according to the intentional call disconnection defined in the call disconnection cause notification system 200 may be included in the normal call disconnection. On the other hand, the cause of the abnormal call disconnection may be any disconnection other than the normal call disconnection, such as when the battery of any one of the communication terminals (210, 240), battery failure, terminal failure, network failure occurs. . The network failure is caused when one of the communication terminals 210 and 240 is located in a blind spot of radio waves such as a shaded area (for example, a mountain area, a place covered by a building, or an area where communication service is not provided). May occur.

The message receiving party selection unit 340 determines a message receiving party indicating the counterpart terminal of the side providing the cause of the abnormal call disconnection according to the analyzed cause of the disconnection.

As an example of determining the message receiving target, the message receiving target selecting unit 340 may default to simply terminate the call without any message as in the prior art when a normal call disconnection occurs. In addition, the message receiving target selector 340 may transmit the cause of the abnormal disconnection only when the mobile communication terminal 210 or the counterpart terminal 240 requests the cause of the disconnection. In addition, the message reception target selector 340 is configured to send the text message to the counterpart terminal of the terminal that caused the disconnection cause when the abnormal disconnection occurs, the mobile communication terminal as possible The call disconnection cause may be transmitted to both the 210 and the counterpart terminal 240.

Therefore, when an abnormal disconnection occurs, at least the counterpart terminal side of the terminal that caused the disconnection cause can identify the cause of the disconnection to prevent misunderstanding. In addition, since the cause of the call disconnection can be predicted more easily than the counterpart terminal (for example, the cause can be easily estimated when hiking or located in an island area). The user of may decide to receive the text message according to the selection.

The message transmitter 350 transmits the cause of call disconnection according to the extracted corresponding code to the determined message receiver in the form of a text message. An example of such a text message is shown in FIG. 4.

It is an example of a text message that can be received when a call break occurs. Therefore, the user of the mobile communication terminal 210 can easily identify where the cause is when the call is abnormally interrupted. In addition, the counterpart terminal 240 may receive a text message as shown in FIG. 4 (b) so that the user can solve the problem by himself / herself so as to know where the cause of the call disconnection occurs.

The text service may be a short message, a multimedia message, a long message, or an integrated message transmitted and received through a short message service (SMS), a multimedia message service (MMS), a long message service (LMS), or a unified message service (UMS). It may be transmitted to one or more communication terminals by any one of means.
