By communicating with the control unit through the I / O interface, the user can call any GSM terminal using his / her own phone number by simply mounting his SIM card.

2 is a flowchart illustrating a method for requesting additional switch service in a conventional GSM digital cellular system terminal.

Hereinafter, a method for requesting additional service of a conventional GSM system cellular system terminal will be described in detail with reference to Tables 1 and 2, which are configured in the terminal of FIG. 1 based on the flow of FIG. 2.

First, in step 201, the controller 10 searches for key input through the key input unit 80. In this case, if there is a key input, in step 203, the controller searches whether the key input is a send key. If the key found in step 203 is not a send key and the key (*, #, * #, **, ##) requesting the additional service shown in Table 1, the controller 10 proceeds to step 205. The input key is displayed through the display unit 90. If another function key input is detected, the corresponding function routine is executed.

Thereafter, in step 207, the controller 10 stores the corresponding data of the key input in the memory 20 and returns to step 201. When the send key input is detected in step 203, the controller 10 transmits key data stored in the memory 20 to the base station through the transmitter 70 as a message in step 209.

That is, the order of the key input follows the format of the key input format shown in Table 1.

Through the above-described key input sequence, the GSM type cellular system terminal is provided with an additional service function.

However, the additional service request method of the conventional GSM-type cellular system terminal, as described above, was inconvenient to memorize each service code or view a manual when a user requests additional service through the terminal. In addition, when there is no memorization of the corresponding service code or there is no manual, it is impossible to request an additional service, and there is a problem such as input error due to memorizing error of the above-described service code and parameters corresponding to each service code.

Accordingly, an object of the present invention is to store additional service input regulation information of a mobile system in a global system in a memory so that the additional service request key input process is simply performed as an interactive input method through a control unit of a terminal and a key input unit and a display unit of a terminal. The present invention provides a method for requesting an additional service of the end of the GSM cellular system which can perform key input.

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

3 is a flowchart illustrating a method for requesting additional service in a GSM digital cellular system terminal according to an embodiment of the present invention.

The control unit of the GSM-type digital cellular system terminal including a memory storing the global system mobile type additional service input rule information first searches for the additional service key input by searching the key input unit 80 in step 301. In this case, the additional service key may be a selection key selected by the user while viewing the display together with other general service items, and a separate key for generating a key code corresponding to a separate additional service may be used as a function key. have.

If the additional service key input is found in step 301, the controller 10 displays a service item corresponding to the additional service key input on the display unit 90 in step 303. The service items represent the high frequency of use among the additional service items shown in Table 2, for example, Call Forwarding Unconditional (CFU), Call Forwarding (CF), Barring of Outgoing Calls (BAOC), BArring of Outgoing International Calls (BAOIC) and the like.

Subsequently, in step 305, the control unit 10 responds to the corresponding item (Call Forwarding Unconditional (CFU), Call Forwarding (CF), BArring of Outgoing Calls (BAOC), BArring of Outgoing International Calls (BAOIC)) through the key input unit 80. Search for keystrokes to do.

Looking at an example of the display of the key input request corresponding to the corresponding item,

1: Call Forwarding Unconditional (CFU)

2: Call Forwarding (CF)

3: BArring of Outgoing Calls (BAOC)

4: BArring of Outgoing International Calls (BAOIC)

As shown in the figure, corresponding items may be sequentially displayed.

Thereafter, if a key input is found in step 305, the controller 10 searches whether the selected key input of the corresponding item is correct in step 307. That is, according to the display example, it is searched whether there is a corresponding numeric key input.

At this time, if a key error (in accordance with the display example, other key input other than the corresponding numeric keys) occurs, the process returns to step 303 to display the additional service item and request selection. However, if the selection key input of the corresponding item is correct in step 307, the controller 10 performs a selection item display operation of displaying only the corresponding item for a predetermined time through the display unit 90 in step 309. Here, it is a matter of course that the above-described selection item display operation of step 309 has various embodiments. If another example is provided, only the selection item among the five item display may be selected as the display on / off operation at regular intervals.

Thereafter, in step 311, the controller 10 stores the key code corresponding to the selected item in the memory 20.

In step 313, the controller 10 displays the operation type (operation, stop, inquiry, registration, deletion) corresponding to the additional service selection item on the display unit 90.

Looking at an example of the display of the key input request corresponding to the operation type,

"1: Operation 2: Stop 3: Contact 4: Register 5: Delete"

As shown in the figure, an operation type can be indicated.

Thereafter, in step 315, the controller 10 searches whether the key input corresponding to the operation type (the numeric key input of 1-5 according to the display example) is performed through the key input unit 80.

Then, if a key input is found, the control unit 10 searches whether the selection key input of the operation type is correct. That is, according to the display example, it is searched whether there is a key input corresponding to 1-5.

At this time, if a key error (key input other than 1-5 according to the display example) occurs, the process returns to step 313 to display the operation type again and request the correct selection of the operation type. However, if the selection key input of the operation type is correct in step 315, the control unit 10 performs a display operation indicating the operation type selection through the display unit 90 in step 317.

In operation 319, the controller 10 stores the keycode corresponding to the selected item (keycode of the selected item among *, #, * #, **, ##) in the memory 20.

In step 321, the controller 10 performs a service selection, parameter input request, selection error search, display of selected parameters, and storage of selected parameter data according to the operation type selection and storage process of steps 313 to 319 described above. . In this case, when the service code selection request is made in response to the additional service item selection, only the service code related to the additional service item is displayed instead of displaying all the service codes, thereby reducing the user's code search time.

Referring to FIG. 4, the parameter input step of step 321 will be described in detail. First, in step 401, the controller 10 determines the number of necessary parameters corresponding to the input format corresponding to the service code stored in step 319. Temporarily stores in the controller 10 and initializes the parameter No to 0.

In step 403, the controller 10 displays an input desire of a parameter (including a service code) through the display unit 90. In step 405, the key input is searched for whether the parameter input is correct. At this time, if a key input other than the designated selection key is found, the process proceeds to step 403.

When the correct parameter input is found, the controller 10 displays the input contents through the display unit 90 in step 407 and stores the keycode in the memory.

In step 409, the controller 10 increases the parameter No variable by one. In step 41, if the required number of parameters specified in step 401 and the parameter No variable are compared, the parameter is recognized to be complete and the corresponding parameter subroutine ends.

After that, in step 323 of the main flow diagram of FIG. 3, the controller 10 searches whether the input of the parameter of the operation is completed and repeats the operation 321 if the input is not completed. Perform step 325.

In step 325, the controller 10 transmits the data stored in the memory 20 to the base station through the transmitter 70 as an additional service request message in the course of performing the above-described steps.

In the above-described process, selection labels and data of each item and parameter displayed through the display unit 90 under the control of the controller 10 are initially stored in the memory 20 by the manufacturer.

In the above-described process (10) under the control of the display unit 90, the selection mark and the data of each tree and the parameters displayed by the manufacturer is initially stored in the memory 20.

Hereinafter, the above-described process will be briefly described as an example of the following key input.

First, in step 305, the user adds "BAOC" as an additional service item (in this case, the control unit 10 processes the service code "33" internally), and in step 315, the operation type is "1: designation" and the first parameter designation (PW). If "1234" is selected as "10" in the second parameter designation (BS: service range designation), the entire format for the additional service items stored in the memory is as follows.

* 33 * 1234 * 10 #

The format is meant to prevent outgoing calls for all kinds of telephony services. Therefore, it is stored in the memory corresponding to the key format and then sent as a message.

As described above, the present invention has been illustrated in the drawings and described in the embodiments, but the present invention is not limited thereto, and various modifications and changes can be made without departing from the basic definition of the present invention. Anyone with knowledge will know it clearly. For example, the steps 303 to 311 are processes for increasing the speed of service code selection at step 321. Thus, the steps 301 and 313 to 327 are deleted as another embodiment according to the present invention. It can also be configured.

As described above, the present invention stores the key input information of each format for the additional service item according to the additional service input rule of the global system mobile method in a memory and displays respective items according to the user's selection through the user and the key input unit. By inputting in an interactive format, there is an advantage that a user can request additional service through the GSM cellular system terminal without memorizing the format and parameters of the GSM additional service item described in the manual and without referring to the manual.

In addition, the present invention has the advantage that it is possible to input the correct additional service request by selecting the items stored in the memory.
