Abstract

The present invention relates to a method for notifying a call connection failure of a mobile communication terminal. In particular, an object of the present invention is to notify a user of a failure when a call connection fails for a terminal call so as to make a smooth call by taking appropriate measures. According to the present invention, when a terminal receives a call message from the base station, the terminal transmits a call response message to the base station, and if the base station does not receive the transmitted call response message, the terminal sets a maximum transmission power. Transmitting the call response message repeatedly for a predetermined number of times and if the base station fails to respond even if the call response message is repeatedly transmitted, the terminal displays on the screen that the call cannot be made due to poor communication environment. do.

Description

How to notify call connection failure of a mobile device {METHOD FOR NOTIFYING CALL CONNECTION FAILURE OF MOBILE COMMUNICATION TERMINAL}

1 is a signal flow diagram for call connection in an embodiment of the present invention.

Figure 2 is an operational flow diagram showing a call connection process in an embodiment of the present invention.

Explanation of symbols on the main parts of the drawings

110: terminal 120: base station

The present invention relates to a mobile communication terminal, and more particularly, to a method of displaying a cause when a call connection attempted by a mobile communication terminal fails.

With the spread of current mobile communication terminals, people can talk to any party anytime and anywhere.

In general, when a call request is made at the calling terminal, the base station transmits a response message to the calling terminal and attempts to connect a call to the called terminal.

Accordingly, when the connection response message is returned from the receiving terminal, the base station connects the call path between the calling terminal and the receiving terminal.

However, conventionally, if any other party calls, there is a problem that if the call is not normally made, the cause is not known and the terminal is misjudged.

Accordingly, the present invention for solving the above problems can be repeated by a predetermined number of times when the call is not connected, and in addition, when the call is not connected, an appropriate reason corresponding to the situation can be indicated to the user. An object of the present invention is to provide a call connection failure notification method of a mobile communication terminal.

According to an aspect of the present invention, when a call message is received from a base station, a terminal transmits a call response message to the base station, and if the base station does not receive the transmitted call response message, the terminal transmits power. Transmitting the call response message repeatedly by a predetermined number of times by setting the maximum value to the maximum, and if the base station fails to respond even if the call response message is repeatedly transmitted, the terminal displays that the call cannot be made due to poor communication environment. Characterized in that performing the steps.

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

1 is a signal flow diagram for the call connection between the terminal 110 and the base station 120 in the embodiment of the present invention, as shown in the terminal 110, receiving a call message from the base station 120, The terminal 110 transmits a call response message to the base station 120, and the terminal 110 determines whether or not the call according to the release order or channel assignment message of the base station 120 is received. Configure to perform.

The operation and the effect of the embodiment of the present invention configured as described above will be described with reference to the operation flowchart of FIG. 2.

First, the terminal 110 checks whether a call message is received from the base station 120 in the standby state.

At this time, when the call message is received from the base station 120, the terminal 110 transmits a call response message to the base station 120.

Therefore, when the channel assignment message is received from the base station 120, the terminal 110 uses the assigned channel as a call path.

If there is no call channel to be allocated to the terminal 110 and a release order message is received from the base station 120, the terminal 110 recognizes that there is no call channel and displays it on the screen to notify the user. .

In addition, when the terminal 110 transmits the call response message to the base station 120, a situation in which the wireless environment to which the terminal 110 belongs is deteriorated and thus the base station 120 may not receive the corresponding call response message may occur.

At this time, when the terminal 110 recognizes that the base station 120 does not receive the call response message, the terminal 110 repeatedly transmits the call response message a predetermined number of times. In this case, the terminal 110 may be configured to repeat the channel connection with the base station 120 by setting the transmission power to the maximum.

Therefore, if the call response message is not received even after transmitting the predetermined number of times to the base station 120, for example, when the call message is received and the terminal 110 transmits the call response message to the base station 120, the base station 120 If the transmission power of the terminal 110 is not recognized, the terminal 110 notifies the user by displaying on the screen that a call is impossible due to a poor communication environment.

That is, when the terminal 110 recognizes the transmission power from the base station 120 but the base station 120 does not recognize the transmission power of the terminal 110, the terminal 110 displays a call impossible on the screen to notify the user. do.

In this case, the user can move to a better communication environment, wait for a call, and then talk normally.

As described in detail above, the present invention repeatedly attempts to connect a call a predetermined number of times when a call is not connected, and when a call is not connected, the present invention displays a proper reason corresponding to the situation and informs the user. It is possible to improve the user's call satisfaction by allowing the user to take appropriate measures in response to the reason that the call is not connected.

Claims (2)
