The present invention relates to a mobile communication terminal system equipped with a group incoming function and a control method thereof. In particular, the mobile communication terminal registers a call forwarding for each group or team and registers it in a base station. The present invention relates to a mobile communication terminal system having a group call function for transferring a call to one of the remaining terminals of the group when the terminal is absent and a control method thereof.

In general, wireless data communication refers to a communication function of wirelessly transmitting and receiving various data such as letters, numbers, and images through a base station system using a portable terminal capable of wireless transmission and reception. For example, it is a mobile communication system that exchanges or retrieves data in both directions while moving by using various terminals such as a cellular phone, a portable computer, a facsimile, and a credit card inquiry machine.

Especially in the early 1980s, mobile phones divided the service area into hexagonal cells of several km to several ten kilometers in diameter in North America, and then repeatedly used the same frequency channel in geographically separated cells. As a result, cellular phones that implement radio channel switching between cells have grown rapidly for the first time. In addition, such a mobile phone provides various service menus on the terminal for the convenience of the user. For example, a short message service (SMS), an e-mail transmission, and an Internet connection are provided. At this time, the SMS data signal is usually limited to within 80 bytes when transmitted to the terminal.

Then, referring to the conventional mobile phone system as described above with reference to Figure 1, the base station system unit 72 for wirelessly processing function signals, for example, SMS or e-mail account access signal transmitted from a plurality of mobile phones (70, 71) and And an SMS server 73 connected to the base station system unit 72 to provide an SMS account to the mobile phones 70 and 71.

On the other hand, looking at the operation of the conventional mobile phone system as described above, first, when the user of the mobile phone 70 presses the telephone number signal for the call, the telephone number signal is wireless signal processing by the mobile phone 70 base station system unit Is sent to 72. In addition, the base station system unit 72 connects the call signal of the inputted mobile phone 70 to the other party's mobile phone 71 through the base station system unit 72 in the vicinity of the mobile phone 71. When the call is formed by the above process, the mobile phone 70 executes a normal call with the counterpart mobile phone 71.

Here, when the user of the mobile phone 70 inputs the SMS data to the mobile phone 70 within 80 bytes to transmit the SMS data, the mobile phone 70 loads the input SMS data into the data burst message to the base station system unit 72. Via the transmission to the SMS server 73. Then, the SMS server 73 notifies the counterpart receiving terminal 71 of the SMS reception via the base station system unit 72. At this time, the SMS server 73 transmits this SMS data to the counterpart terminal 71, if desired by the user.

However, the conventional mobile communication terminal as described above is continuously ringing when a person in the vicinity of his or her mobile communication terminal leaving the call or when you can not handle the call of the mobile communication terminal because the call to another phone Will be ringing for a certain period of time, which significantly interfered with the work of the people around you. Even if you try to handle the call of the mobile terminal on behalf of the absent person, you must go directly to the place where the terminal is located. There is a problem that causes a great inconvenience in the convenience of use of the terminal.

    Accordingly, the present invention has been invented to solve the above-mentioned general problems, and when the call request of the terminal cannot be processed according to the absence of the user, the remaining terminals of the group are forwarded to process the call accordingly. It is an object of the present invention to provide a mobile communication terminal system and a control method with a group incoming function that can maximize the functionality of the terminal.

Another object of the present invention is that it is possible to handle the missed terminal call to the call forwarding his own terminal without having to move the current seat to receive the call of the missed terminal, so that the convenience of use of the mobile communication terminal is significantly improved accordingly. The present invention provides a mobile communication terminal system having a group incoming function and a control method thereof.

 The present invention for achieving the above object is a mobile communication terminal for setting a function to search for a missed call by the same group specified in the call forwarding, and a group-specific phone number designated by the mobile communication terminal as a missed call forwarding function server If the registered telephone number is not answered, it is composed of the base station system unit which forwards the message to other telephone numbers in the same group and forms a call. Provided is a mobile communication terminal system having a group call function.

Another feature of the present invention is a missed call forwarding group setting step of setting and setting a phone number for requesting missed call forwarding in a mobile communication terminal for each group through a base station system unit, and after the missed call forwarding group setting step, each group is missed. Call forwarding signal to the corresponding terminal when a transmission signal for requesting a call from an external exchange is input after the group forwarding registration step of registering the telephone numbers of the terminals requesting the switching to the base station system unit and the call forwarding registration step for each group. In addition, the group call request step of transmitting a text message containing the fact of the deceased to the phone number of the other terminals registered together with the group, and the call connection signal from the terminal during the group call request step within a certain time Is not entered, it is considered as absent and there is a current call request. From a group terminal call request determination step of checking whether there is a call connection request from another terminal designated as the same group as the corresponding terminal, and from the other terminal assigned to the same group as the corresponding terminal with the current call request by the group terminal call request determination step. When it is confirmed that there is a call connection request, the group call forwarding step is characterized in that it consists of a call forwarding step of a group terminal for executing a normal call by transferring the corresponding call to another terminal that has requested a call within the same group. A control method of a mobile communication terminal system is provided.

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

The apparatus according to the present invention sets a missed call forwarding function designated for each group as shown in FIG. 2 and wirelessly processes various data transmissions including a voice traffic signal, and the mobile communication terminal 1 A base station system unit for registering a telephone number for each group designated as a call forwarding function and a missed call forwarding function and transmitting a call to another registered telephone number when the call is not answered. It is composed of

The mobile communication terminal wirelessly processes the audio signal input and output through the handset 3 and the voice signal input and output through the codec unit 4 and is designated by group. A mobile station modem (5) for setting a switching function, and a key panel (6) connected to the MSM (5) to input a function setting signal of a user.

Next, the operation and effects of the present invention as described above will be described.

The present invention first proceeds to the missed call forwarding group setting step (S2) in the initial state (S1) as shown in Figure 3 to set the phone number requesting missed call forwarding in the terminal by group by the base station system unit . After the missed call forwarding group setting step (S2), the call forwarding registration step (S3) for each group is performed to register the telephone numbers of terminals requesting call forwarding for each group. In addition, after the incoming call transfer registration step (S3) for each group, it proceeds to the call signal input determination step (S3) to determine whether a transmission signal for requesting a call from an external exchange is currently input. At this time, if it is determined during the call signal input determination step (S3) that the transmission signal for requesting a call is not input from the external exchange, the mobile station enters the standby mode and terminates the present function.

However, if the transmission signal for requesting the call is input from the external exchange as a result of the determination during the call signal input determination step (S3), it proceeds to the group call request step (S4) and transmits the call connection signal to the corresponding terminal. The phone number of the rest of the terminals registered as a group also informs the director of the move by a specific message.

On the other hand, after the group call request step (S4) proceeds to the absence determination step (S5) to determine whether the call connection signal is input from the terminal within a certain time. At this time, when the call connection signal is input from the terminal as a result of the determination during the absence determination step (S5), since the normal call mode, the call function is executed and then terminates.

However, if the call connection signal is not input from the corresponding terminal within a certain time as a result of the determination during the absence determination step (S5), it is determined that there is no absence and proceeds to the group terminal call request determination step (S6), and the corresponding terminal with the current call request. It is determined whether there is a call connection request from another terminal assigned to the same group.

If there is no call connection request from another terminal assigned to the same group as the terminal with the current call request as a result of the call request determination step (S6) of the group terminal, the process proceeds to the group call request step (S4) and repeats the loop. Perform.

However, as a result of determining during the call request determining step (S6) of the group terminal, if there is a call connection request from another terminal designated as the same group as the corresponding terminal with the current call request, the call proceeds to the group terminal forwarding step (S7) and the current call price. The call is forwarded to another terminal that requested the call in the same group as the requested missed terminal to execute the normal call.

That is, when executing the call forwarding function for each group in the mobile communication terminals 1A-N of the present invention, the user of the terminal 1A first selects the corresponding group menu through the key panel unit 6. Then, the MSM unit 5 of the mobile communication terminal 1A displays the corresponding menu on the LCD panel 7, in which case, when the user designates a phone number of another terminal 1B-N to be assigned as a group A message asking whether to accept the call forwarding function for each group to the terminal 1B-N is transmitted via the base station system unit 2. When receiving the message from the corresponding terminal 1B-N, the base station system unit 2 registers the telephone numbers of the terminals to approve call forwarding for each group in the internal memory area.

Here, if the above method continues, the telephone numbers of the terminals approving the missed call transfer are registered in the base station system unit 2 as a group.

On the other hand, if there is a call request to any one of the telephone numbers registered for each group after the registration process, the base station system unit 2 transmits a call connection signal to the terminal 1A. Then, the MSM unit 5 of the corresponding terminal 1A recognizes this and informs the outside that the call is received by a bell or other method.

At this time, the base station system unit 2 informs the fact that other terminals 1B-N belonging to the same group as the terminal requesting the call also have a specific message, for example, a text message, other than the bell signal.

Here, if the user of the terminal 1A who has received the call request is absent and cannot receive a call, the user of the other terminal 1N in the same group who receives the specific message receives the specific button, that is, the incoming call request signal from the base station. When transmitting to the system unit 2, the base station system unit 2 forwards the transmission signal currently requested to the terminal 1N which has made the incoming call request.

Then, the user of the forwarded terminal 1N inputs a voice signal to the MSM unit 5 through the handset 3 and the codec unit 4 indicating that the user of the corresponding terminal 1A who has received the call is not available. Let's do it. The MSM unit 5 of the terminal 1N transmits a voice traffic signal through a call channel currently formed in a normal manner.

        As described above, the present invention sets up a call forwarding in a mobile communication terminal for each group or team and registers it in a base station, and if any one of the terminals registered for the group or team is absent, the call is sent to any one of the remaining terminals in the group. By forwarding the call, if the user's absence cannot process the call request of the terminal, the remaining terminals of the group will forward the call to process the call, which has the advantage of maximizing the functionality of the mobile communication terminal accordingly. have.

In addition, according to the present invention, the call of the missed terminal can be handled by the forwarded own terminal without having to move the current seat to receive the call of the missed terminal instead, thereby greatly improving the convenience of use of the mobile communication terminal. There is also an effect.
