Abstract

PURPOSE: A method for selective call forwarding in a communication terminal is provided to connect a special call to a specific number while using a voice mail box service for general calls which do not need call forwarding. CONSTITUTION: If a call comes in, a bell of a terminal rings while displaying a calling telephone number and information(name) inputted to the calling telephone number(301,302). By referring to an incoming transfer table, it is confirmed whether the calling telephone number is a preliminarily stored telephone number(303,304,305). If the calling telephone number is the preliminarily stored telephone number, an incoming transfer telephone number in called people's absence is dialed to connect the call(306,307). If the calling telephone number is not registered, incoming is denied or the call is transferred to a voice mail box(308).

Description

Selective call forwarding method in telecommunication terminal

According to the present invention, any call received in the absence of a wired / wireless terminal capable of calling number display (CID) (a call requiring call forwarding of a family member, a lover, a friend, a customer, etc., an unnecessary call requiring no call forwarding or no call forwarding, etc.) The present invention relates to a selective call forwarding method for selectively forwarding or rejecting a call forward.

A commonly used mobile communication terminal includes a user information input unit for inputting user information and a display device for displaying the input information and schedule information in a visible state. Examples of such information processing devices include digital portable telephones (cellular phones), electronic notebooks, personal digital assistants (PCS phones), IMT-2000 (International Mobile Telecommunication 2000), and PDA (Personal Digital Assistant). Such portable mobile communication terminals generally perform processing of user information and performing various functions according to a user's request.

In general, when a call is received by the mobile communication terminal, the mobile communication terminal alerts the user of the call to the lake, that is, rings or vibrates to alert the user that there is an incoming call. When the mobile communication terminal user responds to the incoming alert, the call is started with the calling party.

As a supplementary service related to a communication terminal, for example, when a user of a mobile communication terminal is absent or leaves the terminal at home or a company, a voice mail service (VMS) is used to store a voice message or leave only the calling number. To be delivered to the mobile communication terminal. Recently, wired terminals also store voice messages in their own memory or leave a calling number by using a caller ID (CID) service.

However, the voice message recording function or caller ID (CID) service is currently provided in wired and wireless communication terminals, and even if the user is absent, it is possible to check incoming information or recorded voice message later, but it must be received in real time. There is a situation where the terminal user misses an emergency call before confirming the information.

Therefore, as a solution to this problem, a call forwarding service is provided, which provides a net function that does not miss the call forwarding information in the absence or when the user leaves the terminal at home or company, but all incoming calls that are forwarded to the call forwarding terminal are set. Since call forwarding is performed, there is a problem that a call is not required or is not forwarded.

The present invention has been proposed to solve the above problems, and any call received in the absence of a wired or wireless terminal capable of calling number display (CID) (calls, calls that need to be forwarded, such as family, lovers, friends, customers, etc.) It is an object of the present invention to provide a selective call forwarding method for selectively forwarding or rejecting a call that does not need to be forwarded or does not want to be forwarded.

According to an aspect of the present invention, there is provided a call forwarding method in a communication terminal, comprising: a first step of constructing a call forwarding table for a number for which call transfer selection is desired and a number for call transfer dialing (call forwarding number); A second step of checking incoming calls and determining whether an incoming number (calling number) is registered in a call forwarding table; And a third step of bringing the call forwarding number to be transferred and dialing the call forwarding number when the caller ID is registered in the call forwarding table according to the determination result of the second step, and transferring the call forwarding connection. Characterized in that made.

The present invention may further include a fourth step of switching to a call rejection or voicemail according to a known method when the calling number is not registered in the call forwarding table according to the determination result of the second step. Characterized in that made.

According to the present invention, unlike the service of collectively converting an incoming call received in an absence into a predetermined random number, the incoming call number is checked to selectively forward only the calling number previously designated by the terminal user. Of course, for the outgoing call number that is not specified, the call forwarding or voicemail is switched. Therefore, all missed calls are forwarded without specifying a specific calling number, so that a call that does not need to be forwarded or does not want to be forwarded can be prevented from being transferred.

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 the present invention, selective call forwarding or rejection is possible in all wired / wireless terminals capable of calling number display (CID), but it will be described assuming a mobile communication terminal as a preferred embodiment.

1 is an exemplary configuration diagram of a mobile communication terminal to which the present invention is applied.

The control unit 10 of the mobile communication terminal controls the overall operation of the terminal and at the same time controls the selective call forwarding method according to the present invention. Then, control of various components provided is achieved.

The voice memory 11 stores various voice data.

The memory 12 stores an operation program and a system program of the controller 10, and the operation program and the system program are usually stored in a ROM area included therein and can be erased as necessary. Electrically erasable ROMs include EEPROM and flash memory. The memory 12 also includes RAM for temporarily storing data generated during the execution of various operating programs.

In particular, the memory 12 stores an optional call forwarding program. A more detailed description thereof will be described with reference to FIGS. 2A and 2B.

The key input unit 13 includes a plurality of numeric keys, menu keys, and function keys for performing various functions, and outputs key data to the controller 10 by external operation.

In particular, the key input unit 13 is provided with a call forwarding on / off button, the location of the call forwarding on / off button is one of the existing keypad (0 ~ 9, *, #), navigation keys, function keys, side direction keys Can be set for the call forwarding on / off button or a new key can be added to the terminal. In addition, if you know a shortcut key, you can set the call forwarding mode by pressing the call forwarding setting shortcut key, it is possible to cancel the call forwarding mode setting by pressing the call forwarding release hot key.

The display unit 14 is a display device such as a liquid crystal display (LCD) and the like, and displays the state of the mobile communication terminal or the progress of the program under the control of the control unit 10. That is, the overall state of the mobile communication terminal and input user information are displayed.

The controller 10 reads the menu from the memory 12 and displays the menu on the display unit 14 in response to a user's menu display request by the key input unit 13. That is, the key input unit 13 is a conventional user information input means, and has a plurality of keys suitable for a mobile communication terminal to be applied, such as a number of numeric keys and function keys, and if there is an input of each of the provided keys, Therefore, by outputting the corresponding unique key data to the control unit 10, through the key input operation of the key input unit 13 to enter and release the selective call forwarding mode is made. Then, the controller 10 controls the selective call forwarding setting and release according to the corresponding key input.

The RF unit 15 is controlled by the controller 10 and converts a signal output from the controller 10 into a radio signal. In addition, the RF unit 15 converts the radio signal received through the antenna into a desired signal and outputs it.

The ring tone generator 16 generates a ring tone through the speaker under the control of the controller 10.

The voice processor 17 modulates the voice signal input from the microphone to convert the voice signal into voice data, demodulates the voice data input from the RF unit 15 and the voice data stored in the voice memory 11 into voice signals. Sound is output through a speaker.

In order to implement the present invention, the key input unit 13 is composed of a number button, a symbol button, and other functions used to input necessary information to the terminal, and in particular, is used when a user sets / releases a call forwarding mode. It serves to output the signal input by the user to the control unit 10, the control unit 10 serves to switch or cancel the call forwarding mode according to the signal input from the key input unit (13).

Next, the selective call forwarding setting / release process will be described in detail with reference to FIGS. 2A and 2B.

In general, a mobile communication terminal is switched to a voicemail or leaves a caller number when a call is not received. However, in the present invention, a caller ID service and a call transfer service are used to switch the call to another number by user selection. Use at the same time. Therefore, a terminal (including a wired / wireless terminal capable of CID service) should be able to distinguish whether a designated number is specified when checking a calling number by designating a specific number or group, and should be able to dial a connection by dialing the designated number.

To this end, as shown in Figures 2a and 2b, there is a menu that can specify the number or group that you want to be transferred to the call in the terminal, so that the user can select, and switching for the selected item (calling number) dialing Enter the number to be used. In this state, when the caller attempts to make a call, the call is switched to a preset number after dialing for a predetermined time.

In other words, unlike the service of collectively switching the incoming call received in the absence to the specified random number, as shown in Figs. 2A and 2B, the calling party number (family, lover, friend, customer) designated by the terminal user in advance by checking the calling number Call forwarding, etc.) is selectively forwarded only to the specified number (call forwarding number). Of course, for unspecified caller ID (unnecessary call forwarding does not need or do not want to call forwarding) is switched to the rejection or voice mail.

However, as shown in FIGS. 2A and 2B, in addition to only forwarding calls for calls that need to be forwarded (registered phone numbers), the call forwarding numbers may be different even if calls are not required. Can be configured. For example, a call forwarding number for registered telephone numbers is "A number", and a call forwarding number for unregistered telephone numbers is "B number".

In addition, as shown in FIG. 2A, only one call forwarding number may be designated in a batch for a call (registered phone number) requiring call forwarding, or a call requiring call forwarding as shown in FIG. 2B (registration). Phone number) can be specified by different call forwarding number for each group (family, relative, company, customer, etc.). For example, as shown in FIG. 2B, a call forwarding number from a phone number registered as a family group is called "A number", and a call forwarding number from a call number registered from a company, a customer group, or the like. It is called "B number".

For the selective call forwarding service of the present invention, as shown in Figs. 2a and 2b, a selective call forwarding target phone number and a phone number (call forwarding number) to which a call transfer can be made upon incoming call from the corresponding call forwarding target phone number is a terminal. It should be registered in (CID Serviceable Wired / Wireless Terminal).

With the optional call forwarding information registered, when the calling party tries to make a call, the terminal rings and displays the calling number and the information (name) entered in the corresponding number. If the number is registered, the call forwarding number for the registered number is dialed again. This allows the user to selectively switch according to the incoming number in the form of combining the function of sending a confirmation message to the mobile communication terminal when the voice message is left and leaving a voice message and the function of redialing to a specified number when the telephone connection is not established. The function was added.

3 is a flowchart illustrating an exemplary call forwarding method according to the present invention.

First, for the selective call forwarding service of the present invention, as shown in FIGS. A telephone number (call forwarding number) to which a call can be made must be registered on the terminal (wired / wireless terminal capable of CID service).

As shown in Figure 3, the selective call forwarding method according to the present invention, first when the call incoming (301), ringing the terminal and displays the calling number and the information (name) entered in the corresponding number (302) 2), the call forwarding table (see FIGS. 2A and 2B) checks whether the calling number is a registered number (303, 304). That is, it checks whether the incoming caller ID is the same as the caller ID (the call requiring the call forwarding of a family member, a lover, a friend, a customer, etc.) previously designated by the terminal user.

As a result of the check, if the incoming call number is a registered number, the call forwarding number is transferred to the call forwarding number (305) by dialing the corresponding call forwarding number (306).

As a result of the check, the unregistered calling number (unnecessary call forwarding or unnecessary call that does not want to be forwarded) is switched to call rejection or voicemail (308). Of course, it is possible to configure a call forwarding number, unlike the registered phone number for the unregistered phone number. For example, a call forwarding number for registered telephone numbers is "A number", and a call forwarding number for unregistered telephone numbers is "B number".

Here, only one call forwarding number may be assigned to the registered phone number in a batch, or the call forwarding number may be differently designated for each group (family, relative, company, customer, etc.) of the registered phone numbers.

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 general call (call forwarding does not necessarily need to use a voice mail service as before, and must be connected or can be connected to a specific number for a particular call can be connected to the convenience of the user of the terminal There is an effect that can increase.
