Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mobile communication terminal having a call forwarding reservation function and a control method thereof,

The present invention relates to a mobile communication terminal and a control method thereof, and more particularly, to a mobile communication terminal having a call forwarding reservation function and a control method thereof.

As the popularity of mobile communication terminals has increased recently, mobile communication terminals have become a necessity of life for most people.

Furthermore, more and more people own two or more mobile communication terminals instead of only one mobile communication terminal. For example, two mobile communication terminals may be purchased and used in order to be used separately for business use and personal use.

However, it is inconvenient for a user having a plurality of mobile communication terminals to always carry two (or more) mobile communication terminals. Therefore, for example, one of the two mobile communication terminals may be carried by the user when he or she goes to work at the company, and the other may be used after the user goes home.

However, when the mobile communication terminal has a plurality of mobile communication terminals and only one of the mobile communication terminals is carried, the mobile communication terminal can not receive incoming calls.

In order to solve such a problem, a call forwarding service has been proposed.

That is, when the user of the mobile communication terminal registers a predetermined telephone number for call forwarding in advance in the mobile communication network, the telephone call to the user is connected to the registered telephone number.

For example, if the mobile communication terminal has a business mobile communication terminal and a personal mobile communication terminal, the user can receive a call to the business mobile communication terminal at the time of leaving the office by registering in the mobile communication network.

Conversely, the user may register the call forwarding to the mobile communication network so that the mobile communication terminal receives the incoming call to the personal mobile communication terminal at the time of starting work.

However, as described above, there is an inconvenience that the call forwarding is requested by the user every time when the call forwarding is performed relatively regularly (that is, at work or at work). That is, when call forwarding is repeatedly performed at a relatively accurate time point, it is desired to provide means for automatically performing the call forwarding.

It is an object of the present invention to provide a mobile communication terminal and a control method thereof that automatically perform call forwarding at a specific time according to a user's setting.

According to an aspect of the present invention, a mobile communication terminal for transmitting a call forwarding request signal to a call processing server of a mobile communication network includes a user interface unit; A storage unit for storing a predetermined call forwarding telephone number; A time setting unit for setting a predetermined reservation time according to a call forwarding reservation command of the user through the user interface unit; A time lapse detecting unit for detecting a lapse of time according to the reserved time set in the time setting unit and generating a time lapse detection signal; A request unit for extracting a call forwarding telephone number from the storage unit according to a time lapse detection signal of the time lapse detecting unit and transmitting a call forwarding request signal including the extracted forward call telephone number to a call processing server of the mobile communication network .

According to another aspect of the present invention, there is provided a method of controlling a mobile communication terminal for transmitting a call forwarding request signal to a call processing server of a mobile communication network, the method comprising: storing a call forwarding telephone number; Setting a predetermined reservation time according to a call forwarding reservation command of the user; Detecting a time lapse in accordance with the set reservation time and generating a time lapse detection signal; Extracting a pre-stored forwarding telephone number according to the elapsed time detection signal according to the elapse of the reservation time, and transmitting a call forwarding request signal including the extracted forwarding telephone number to the call processing server of the mobile communication network .

As described above, according to the present invention, if a user of the called mobile communication terminal sets a predetermined reservation time in his / her terminal, call forwarding and cancellation can be automatically performed at the reserved time, thereby enhancing user convenience.

In addition, since a request for call forwarding and release setting to the mobile communication network is not made until the actual reserved time, even if the user frequently changes the reservation time, the signal transmission to the mobile communication network does not occur every time, .

When the mobile communication terminal is turned off or turned off after the reserved time of the call forwarding is reserved and the mobile communication terminal is blinked before the time comes, the mobile communication terminal is turned on again, and the call forwarding operation that can not be executed due to the power- The transmission of the request signal can be made immediately at the time of turning off the power or turning on the power.

FIG. 4 and FIG. 5 are diagrams illustrating a control procedure performed in a mobile communication terminal when the power is turned off or on according to another embodiment of the present invention.

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

The overall system configuration including a mobile communication terminal according to an embodiment of the present invention is shown in FIG.

That is, the overall system includes the destination mobile communication terminal 100, the call forwarding mobile communication terminal 200, the originating mobile communication terminal 300, and the mobile communication network 400.

The mobile communication network 400 includes various devices for ensuring communication between the calling mobile communication terminal 300 and the called mobile communication terminal 100 or the called mobile communication terminal 200, (Mobile Telephone Switching Office) 410 and a Home Location Rocator (HLR) 420. Although not shown, various devices such as a base station controller or a PDSN (Packet Data Serving Node) may be included.

Only the MSC 410 and the HLR 420 of the mobile communication network 400 will be described.

Herein, the MSC 410 performs call processing between mobile communication terminals, and the HLR 420 stores the current location and other additional information of the mobile communication terminal. The MSC 410 and the HLR 420 Since the function is only known, the detailed description of the functions will be omitted. Since the call processing between the MSs 410 and the HLR 420 is performed by the mutual operation of the MSC 410 and the HLR 420, the call processing server and the MSC 410 can be collectively called the call processing server.

Meanwhile, in the present embodiment, the calling-side mobile communication terminal 300 corresponds to a mobile communication terminal operated by a user who makes a call, and the called-side mobile communication terminal 100 and the call- And mobile communication terminals that receive a call from the mobile communication terminal 300. [

For convenience of explanation, the called mobile communication terminal 100 is a mobile communication terminal corresponding to a telephone number to which the calling mobile communication terminal 300 originally requests connection, and the called mobile communication terminal 200 is a mobile communication terminal, Side mobile communication terminal 100 and the actual call is connected to the calling-side mobile communication terminal 300. In this case,

That is, even if the originating mobile communication terminal 300 calls the called mobile communication terminal 100, if the call forwarding is set in the mobile communication network 400, the originating mobile communication terminal 300 And the call is connected to the call forwarding mobile communication terminal 200.

Functions of the called mobile communication terminal 100 for performing such functions will be described with reference to the functional blocks of FIG.

1, the mobile communication terminal 100 includes a user interface unit 110, a time setting unit 120, a time lapse unit 120, A storage unit 140, a request unit 150, a power state detection unit 160, and a reservation state determination unit 170. The determination unit 170 may include a detection unit 130, a storage unit 140, a request unit 150,

Here, the user interface unit 110 may be configured by a keypad including a predetermined button, for example, to input a predetermined command by a user's operation.

The storage unit 140 stores a predetermined forwarding telephone number, and the incoming telephone number may be stored by being input by the user. The storage unit 140 may be a nonvolatile memory that stores the stored data even when the power is turned off.

The time setting unit 120 sets a predetermined reservation time or an unscheduled reservation time according to a call forwarding reservation command of the user through the user interface unit 110. For example, when the call forward start time and the call forward end time are time And may be set in the setting unit 120.

The time lapse detection unit 130 detects a lapse of time according to the reservation time or the release reservation time set in the time setting unit 120 and generates a time lapse detection signal. For example, the time lapse detection unit 130 may include a predetermined timer (not shown) to generate a time lapse detection signal when a preset time set in the time lapse detection unit 130 arrives according to the operation of the timer.

The request unit 150 extracts the forwarding telephone number from the storage unit 140 according to the time lapse detection signal of the time lapse detection unit 130 according to the reservation time and transmits a call forwarding request including the extracted forwarding telephone number And transmits a signal to the call processing server of the mobile communication network 400.

In addition, the request unit 150 may transmit a call forwarding release request signal to the call processing server of the mobile communication network 400 according to a time lapse detection signal of the time lapse detection unit 130 (according to the release reservation time).

In particular, the power state detection unit 160 detects whether the mobile communication terminal is powered off or turned on, When it is turned on, it detects it.

Here, turning off the mobile communication terminal means, for example, turning off the power by pressing the power button provided on the user interface unit 110 for a long period of time, and turning on the mobile communication terminal means that the power button is short- It can mean something.

Therefore, when the power is turned off, the power state detecting unit 160 detects that the mobile communication terminal is turned off and detects a newly turned on state.

Also, the power state detection unit 160 detects a state change request to turn off the power of the mobile communication terminal or turn on the power. Particularly, the power state detection unit 160 detects a power off request of the mobile communication terminal by the user.

For example, when the user presses the power button for a long time, the power state detection unit 160 detects the power state change request.

The reserved state determination unit 170 determines whether or not a predetermined reservation time is set in the time setting unit 120 as the power state detection unit 160 detects the state change from the power OFF state to the power ON state .

In addition, the reservation state determination unit 170 determines whether a predetermined reservation time is set in the time setting unit 120 as the power state detection unit 160 detects a state change request from the power-on state to the power-off state by the user .

That is, when the power is newly turned on, the reservation state determination unit 170 detects a power off request from the user and determines whether a predetermined reservation time is set in the time setting unit 120. [

If the predetermined time is set in the time setting unit 120 as a result of the determination by the reservation state determination unit 170, the time lapse detection unit 130 described above sets the predetermined reservation time set in the time setting unit 120 And the current time can be compared with each other, and the time lapse detection signal can be immediately generated according to the comparison result, which will be described later in more detail.

Hereinafter, a control procedure of the mobile communication terminal according to an embodiment of the present invention will be described with reference to FIG.

In the description of this embodiment, it is assumed that the mobile communication network 400 is provided with the MSC 410 and the HLR 420 as a call processing server. For convenience, the destination mobile communication terminal 100 is indicated by "A", the call forwarding mobile communication terminal 200 is indicated by "B", and the originating mobile communication terminal 300 is indicated by "C".

First, the called mobile communication terminal 100 sets and stores a telephone number of a terminal to which call forwarding is to be switched according to a user's selection (step S1).

Similarly, according to the selection of the user, the called mobile communication terminal 100 sets and stores the call forward start time and the call forward end time (steps S3 and S5).

Thereafter, the called mobile communication terminal 100 checks the time (step S7) and determines whether or not it has reached the call forward start time (step S9).

When it is determined that the call forwarding start time has been reached, the called mobile communication terminal 100 transmits a call forwarding setting request signal including the pre-stored forwarding telephone number to the MSC 410 via the base station (step S11). Accordingly, the MSC 410 transmits the call forwarding setting information to the HLR 420 (step S13), and the HLR 420 stores the received forwarding setting information (step S15). That is, the telephone number of the call forwarding mobile communication terminal 200 is registered in the HLR 420 in response to the called mobile communication terminal 100.

On the other hand, if there is a call attempt from the originating mobile communication terminal 300 to the called mobile communication terminal 100 (step S17), the MSC 410 inquires the call forwarding setting information through communication with the HLR 420 (Step S19), and performs call connection to the call forwarding mobile communication terminal 200 (step S21).

Accordingly, the originating mobile communication terminal 300 performs call processing with respect to the called mobile communication terminal 200, not the called mobile communication terminal 100 that originally tried to connect, and performs a termination process upon completion of the call (Step S23).

On the other hand, the called mobile communication terminal 100 continuously checks the time (step S25) and judges whether or not the call forward end time has come (step S27).

As a result of the determination, when the call termination end time is reached, the called mobile communication terminal 100 transmits a call termination cancel request signal to the MSC 410 (step S29). Then, the MSC 410 transmits the call forwarding cancellation information to the HLR 420 (step S31), and the HLR 420 performs the call forwarding cancellation process (step S33).

Here, performing the call forwarding cancellation process may mean deleting the phone number of the call forwarding mobile communication terminal 200 stored corresponding to the called mobile communication terminal 100. [

When there is a call attempt from the calling mobile communication terminal 300 to the called mobile communication terminal 100 (step S35), the MSC 410 inquires the call forwarding setting information through communication with the HLR 420 (Step S37). Since the call forwarding is released, the MSC 410 performs call connection to the called mobile communication terminal 100 (step S39).

Accordingly, the calling-side mobile communication terminal 300 performs a calling process with the called-party mobile communication terminal 100 that has originally attempted to connect, and performs a termination process upon completion of the calling (step S41).

Accordingly, if the user of the called mobile communication terminal 100 sets a predetermined reservation time in his / her terminal, the call can be automatically switched and canceled at the reserved time, thereby enhancing user convenience.

In this case, since a request for call forwarding and cancellation setting to the mobile communication network 400 is not made until the actual scheduled time, even if the user frequently changes the reservation time, the signal transmission to the mobile communication network 400 does not occur So that it is possible to prevent the occurrence of unnecessary signals.

4 and 5, a process for requesting call forwarding when the power of the mobile communication terminal is newly turned on or off will be described.

First, FIG. 4 illustrates a case in which the called mobile communication terminal 100 is newly turned on in a power-off state.

When the user presses the power button of the called mobile communication terminal 100 and the receiving mobile communication terminal 100 is turned from the OFF state to the ON state (step S51), the called mobile communication terminal 100 sets the reservation time The storage unit 140 or the like is checked (step S53).

If the inquiry result reservation time is set in advance (step S55), the called mobile communication terminal 100 compares the current time with the reservation time (step S57). If the comparison result shows that the reservation time has passed (step S59 The called mobile communication terminal 100 immediately transmits the call forwarding request signal to the mobile communication network 400 (step S61).

Accordingly, when the call forwarding time is reserved and the mobile communication terminal is turned off after the power of the mobile communication terminal is turned off before the time arrives, the transmission of the call forwarding request signal that has not been executed due to the power- .

At this time, although not shown, the called mobile communication terminal 100 may transmit a call forwarding request signal according to a user's selection after displaying a screen asking a user's selection.

Next, FIG. 5 shows a process when the power of the called mobile communication terminal 100 is turned off.

When the user turns off the power of the called mobile communication terminal 100 by pressing and holding the power button (step S71), the called mobile communication terminal 100 inquires the storage unit 140 or the like whether the reserved time is preset Step S73).

If the inquiry result reservation time has been set (step S75), the called mobile communication terminal 100 compares the current time with the reservation time (step S77). If the comparison result does not reach the preset reservation time (Step S79) The called mobile communication terminal 100 transmits the call forwarding request signal to the mobile communication network 400 immediately (Step S81).

Here, if the current time has elapsed from the preset reservation time, the transmission of the reserved call forwarding request signal has already been performed, and no further processing is performed.

Accordingly, when the call forwarding time is reserved and the power of the mobile communication terminal is turned off before the time comes, the mobile communication terminal performs transmission of the call forwarding request signal that can not be executed due to power off .

At this time, similarly, the called mobile communication terminal 100 may display a screen for asking the user to select and then transmit a call forwarding request signal according to the user's selection.

In the example described with reference to FIGS. 4 and 5, the call forwarding request signal is transmitted. However, it goes without saying that the same process can be performed to transmit the call forwarding cancellation request signal.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention. It is to be understood that such variations and modifications are intended to be included in the scope of the appended claims.
