According to an aspect of the present invention, there is provided a call connection service method applied to a terminal of a wireless communication system, wherein the terminal recognizes that abnormal termination of a call occurs during a user's call and stores information related to the call. Stage 1; A second step of determining that the terminal has recovered from the abnormal call termination state to a call available state; A third step of informing the user that a call can be reconnected with a counterpart station which was abnormally terminated based on the stored call information; And a fourth step of receiving, by the terminal, a call reconnection request from the user and reconnecting a call path to the counterpart station.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In describing the preferred embodiment of the present invention, a mobile communication terminal (mobile phone), which is one of terminals used in a wireless communication system, will be described as an example. Of course, the present invention is not merely implemented through a mobile communication terminal.

2 is a schematic structural diagram of a mobile communication system to which the present invention is applied.

As shown in the figure, a mobile communication system to which the present invention is applied includes a mobile switching center (MSC) 21, a terminal 22 used by a user, and a plurality of base stations 23, 24, 25, and 26. Is done. Of course, not only network switch (MSC) 21, but also various equipment such as home location register (HLR), visited location register (VLR), etc. are required to operate the mobile communication system, but in FIG. 21 is shown. Reference numeral 27 denotes a no service area in which the mobile communication terminal 22 cannot make a call.

The present invention will be described based on a system having such a schematic configuration.

The present invention pops up a pop-up window that can be connected to the call to notify the user when the call is possible with one button for the user who wants to reconnect after the abnormal call.

Looking specifically at this, the following two forms can be given as an example.

First, in the first case, if the battery is discharged during a call and the terminal is turned on by battery replacement / charging after the mobile terminal is powered off, the terminal detects that the abnormal call was terminated when entering the initial screen. . At this time, the call was interrupted with '011-XXX-XXXX (or, if it was a stored phone number, it can be expressed as' anyone') instead of the initial screen. If you want to reconnect, press the [OK] button 'pop-up window. At this time, when the user presses the [OK] button, the call is immediately attempted, and when the cancel button is pressed, the initial screen appears.

Next, look at the second case, while entering the unserviceable area while taking the elevator during the call was disconnected. Let's get into the call area while getting off the elevator. If you want to re-call with 'anybody', please press [OK] button. As soon as the user enters the coverage area, the user can immediately try to make a call.

The present invention provides a convenient function as shown in the above embodiments, but may be inconvenient depending on the user, so that a setting menu may be provided according to the user of the mobile communication terminal.

In addition to the general voice call, the present invention as described above may also be utilized when using a data communication service such as a WAP (NATE) service connection. In addition, each setting may be applied or not applied to the user setting menu according to a voice call or a data service.

3 is a flowchart illustrating a reconnection service method after abnormal call termination according to the present invention.

First, the mobile communication terminal confirms that the user is busy (301). In operation 302, abnormal call termination is detected. In this state, the mobile communication terminal checks whether the reconnection function has been previously set by the user (303). As a result of the check, if the reconnection function has not been set at the end of the abnormal call, the procedure is terminated without a subsequent procedure corresponding to the abnormal end of the call, and then the call is made at the request of the user or a call from the other party.

As a result of checking whether the reconnection function has been previously set by the user, if the reconnection function is set at the end of the abnormal call, the mobile communication terminal stores information related to the abnormal termination of the call (304).

Thereafter, in a situation where a call through the mobile communication terminal is possible, the terminal checks the termination of the call termination cause (305), and grasps information related to the abnormal termination of the stored call (306). In operation 307, the mobile communication terminal informs the user of the call reconnection through a pop-up window. Call reconnection may be attempted by the user pressing a specific button of the terminal based on previously stored information. Of course, depending on the setting, this can be modified. That is, the call reconnection may be attempted by pressing only one button among some buttons displayed on the keypad within a predetermined time while the pop-up window is floating, or may be regarded as requesting call reconnection for all buttons pressed within the predetermined time.

Next, it is checked whether a call reconnection is requested from the user (308). As described above, it may be whether a specific key is input, it may be whether a key is input within a predetermined time, or another form that the terminal can identify.

As a result of checking whether the call reconnection is requested, if the call reconnection is not requested, the service related to the call reconnection is terminated, and the terminal returns to the normal standby state.

As a result of checking whether the call is requested to be reconnected, if the call is requested to be reconnected, the mobile communication terminal may attempt to reconnect the call, and the user may continue the conversation that the call was abnormally terminated.

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

The present invention as described above, the conventional mobile communication terminal enters the initial screen unconditionally at the end of the abnormal call, there is an effect that the call can be made with one button for the user who wants to reconnect after the abnormal call type.

In addition, the present invention has the effect of providing convenience because the user does not need to search or input the phone book by immediately reconnecting to the user's button input once for an abnormally interrupted call.
