Configurations of such a mobile communication system are well known and thus detailed descriptions thereof will be omitted.

2 is a block diagram showing a schematic configuration of a typical mobile communication terminal. As shown in the drawing, the keypad 110 and the display unit 120, for example, a liquid crystal display, may be one of well-known configurations. In addition, the wireless communication unit 130 is configured to include an antenna and RF (RF) circuit for communication with the base station 210. In the present specification, the wireless communication unit 130 is interpreted to encompass not only various versions of CDMA but also existing methods such as cellular, GSM, and W-CDMA, as well as mobile communication methods to be introduced in the future.

The voice processing unit 140 processes digital voice data into an analog voice signal or vice versa, and has a known configuration including an additional circuit such as an audio amplifying circuit or a filter.

The memory 150 is divided into a ROM region in which control program data for controlling the operation of the terminal is stored, a RAM region in which data generated during the terminal control operation are temporarily stored, and an external storage region. The memory 150 preferably stores an application for the call rejection function setting and release mode according to the present invention. The controller 160 basically controls the overall operation of the mobile communication terminal based on the control program data stored in the memory 150.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings in a mobile communication system and a mobile communication terminal having the configuration as shown in FIGS. 1 and 2. 3 is a flowchart illustrating a call rejection setting method in a mobile communication terminal and a system according to an exemplary embodiment of the present invention.

The user of the mobile communication terminal 100 who wants to reject a call for a certain period of time commands a call rejection setting through a keypad operation. The control unit 160 provides a call rejection setting mode according to a user's key manipulation command, and requests that the call rejection period be input through the display unit 120 (step 402) (step 404). The user inputs a period according to the request for rejection period input on the display unit 120. For example, the user inputs a period from 10:30 am on June 16, 2004 to 6 pm on June 16, 2004. will be. The incoming call rejection period input of the user may be made through a text input through a keypad, for example, or may be made through voice input.

When a user rejects period input is input, the controller 160 converts the incoming call rejection period information message including the incoming call rejection period information data according to the generation and transmission method to the mobile communication system 200 through the wireless communication unit 130. In step 408, the method transmits to step S410.

At this time, the mobile communication terminal 100 transmits its own serial number ESN (Electronic Serial Number) as well known. This is to determine whether the mobile communication terminal 100 subscribes to the service in the mobile communication system 200. Since a method of providing a communication service by determining whether a service subscriber is determined by checking an ESN in the mobile communication system 200 is a well-known technology, detailed description thereof will be omitted.

The mobile communication system 200 receives a call rejection period information message transmitted from the mobile communication terminal 100, compresses and converts it to a storage method, and stores it in a database. The mobile communication terminal 100 according to the call rejection period information is received. In step 412, call rejection is set.

The database in which the call rejection period information message is stored may be the HLR 230 or the VLR 240, or may be a database for storing additional call rejection terminal information. When the rejection duration information message received from the mobile communication terminal 100 is stored in the HLR 230 or the VLR 240, it is preferably stored in the information area of the mobile communication terminal 100.

When the mobile communication system 300 requests a call connection from the other mobile communication terminal 300 to the mobile communication terminal 100 (step 414), the mobile communication system 200 establishes a call connection from the other mobile communication terminal 300. In operation 416, it is determined whether the requested time is within a call rejection period of the mobile communication terminal 100.

As a result of determination, when the call connection request time to the other mobile communication terminal 300 is within the call rejection period of the mobile communication terminal 100, the mobile communication system 200 stores the mobile communication terminal ( The call rejection period information message of 100 is transmitted to the other mobile communication terminal (step 418). The call rejection period information message transmitted to the other mobile communication terminal 300 is preferably a voice message. For example, the " mobile communication terminal 100 is 10:30 am on June 16, 2004 to June 16, 2004. " You will be sent a "Don't be called until 6 pm" message.

In an aspect, the mobile communication system 200 may further include transmitting a voice mailbox use message to the other mobile communication terminal 300. Accordingly, when the user of another mobile communication terminal 300 wants to use a voice mailbox, the other mobile communication terminal 300 transmits a voice message input from the user to the mobile communication system 200. The mobile communication system 200 records a voice message transmitted from another mobile communication terminal 300 in a voice mailbox. In addition, the mobile communication system 200 stores and processes information data requested for call connection from another mobile communication terminal 300 during a call rejection period of the mobile communication terminal 100.

According to this aspect of the present invention, the user of another mobile communication terminal 300 is provided with a call rejection period information message of the mobile communication terminal from the mobile communication system 200, thereby suppressing unnecessary call connection requests during the period. Unnecessary load on the mobile communication system 200 is prevented. In addition, in the above description, the call connection request to the mobile communication terminal 100 having the call rejection setting is limited to other mobile communication terminals 300, but the present invention is not limited thereto. Can be applied.

As a result of the determination in step 416, if the call connection request time of the other mobile communication terminal 300 to the mobile communication terminal 100 is not within the call rejection period of the mobile communication terminal 100, steps 448 to 452 of FIG. Is performed. This will be described later.

According to an additional aspect of the present invention, the call rejection period information message transmitted from the mobile communication terminal 100 to the mobile communication system 200 may further include an information message for the call rejection.

That is, after step 404, the mobile communication terminal 100 may further request a reason input for the call rejection on the screen of the display unit 120 (step 406). According to the request displayed on the display unit 120, the user of the mobile communication terminal 100 may input a text for the reason for rejection of the call through a key operation, or perform a voice input through a microphone when a voice input is required. The user enters an information message indicating the reason for the rejection period, for example, "I am on a flight during the rejection period, so please call after the rejection period has passed".

Accordingly, the controller 160 generates a call rejection period information message including the call rejection period information and the information on the reason, and transmits the message to the mobile communication system 200.

4A and 4B are flowcharts illustrating a call reject release method in a mobile communication terminal and a system according to an exemplary embodiment of the present invention. First, referring to FIG. 4A, FIG. 4A is a flowchart for explaining that the incoming call rejection state of the mobile communication terminal 100 is canceled because the call rejection period set by the mobile communication terminal 100 is exceeded.

The mobile communication system 200 compares the call rejection period of the mobile communication terminal 100 with the current time and the call rejection period stored in the database (step 440). If the current time exceeds the call rejection period of the mobile communication terminal 100, the mobile communication system 200 releases the call rejection state of the mobile communication terminal 100 (step 442).

The mobile communication system 200 moves the call connection request information message (the number of missed calls and its phone number) and the voice message stored in the voice mailbox from the other mobile communication terminal 300 during the call rejection period of the mobile communication terminal 100. Transmit to the communication terminal (step 444). Accordingly, the user of the mobile communication terminal 100 can grasp the other party's information that has been sent to them during the call rejection period.

If there is a call connection request from the other mobile communication terminal 300 to the mobile communication terminal 100 in the call rejection release state, the mobile communication system 200 requests a call connection to the mobile communication terminal 100 (step 446) ( Step 448). The mobile communication terminal 100 transmits a call connection response message to the mobile communication system according to the call connection request (step 450). Accordingly, a call path between the mobile communication terminal 100 and the other mobile communication terminal 300 is formed (step 452).

FIG. 4B is a flowchart for explaining that the incoming rejection state of the mobile communication terminal 100 is released by canceling the setting before the incoming call rejection period set by the mobile communication terminal 100. The mobile communication terminal 100 determines whether there is a call rejection release command within the set call rejection period (step 460). If there is a call rejection release command by the user's keypad 110 operation, the controller 160 transmits a call rejection release message to the mobile communication system 200.

The mobile communication system 200 receives a call rejection release message transmitted from the mobile communication terminal 100 and releases the call rejection state of the mobile communication terminal 100 (step 442). Since the following process is the same as described above with reference to FIG. 4A, duplicate description will be omitted.

According to an additional aspect of the present invention, the mobile communication terminal 100 further includes increasing a sleep mode state of a slotted mode to reduce battery consumption after transmitting a call rejection duration information message. Before the rejection period has elapsed or before the call rejection release message is transmitted to the mobile communication system, the slot mode is processed as initially set.

In general, a CDMA mobile communication terminal has a variable called a slot index (slot_cycle_index) in an embedded program. The program including this variable switches the state of the terminal from the sleep mode to the awake mode so that the terminal receives the paging signal of the base station during the waiting time and communicates with the base station.

The program also puts the terminal in awake mode back to sleep mode, reducing the power consumed by the terminal being constantly awake. The alternate sleep mode and the awake mode are called slot modes. That is, the slot mode is for the terminal to switch to the awake mode for a predetermined allocated slot period to monitor the paging channel. The period of the slot for monitoring the signal of the base station in the standby state of the mobile communication terminal is as follows.

Slot cycle length = 1.28 X 2 ^SCI (SCI = 0 to 7) (sec)

As can be seen from the above equation, there are 8 types of slot modes according to the period. Currently, most carriers set the slot index to 2 or less, so the slot cycle length is within 5.12 seconds. That is, when the slot index is set to 2, the mobile terminal enters the awake mode once every 5.12 seconds, and supplies power to the RF module, which is the wireless communication unit 130, for 80 msec. Return to mode.

When the mobile communication terminal 100 sets the call rejection according to the preferred embodiment of the present invention, it is preferable to set the slot mode by selecting a slot index value greater than two. In one embodiment, if the SCI is set to 7, the slot cycle length is 163.84 sec so that the mobile communication terminal 100 supplies power to the RF module once every 163.84 seconds to communicate with the base station. 5 is a view comparing currents consumed by the mobile communication terminals according to slot modes. As shown, it can be seen that the larger the SCI value, the smaller the current consumption.

In this way, it is possible to reduce the unnecessary power consumption of the battery by increasing the sleep mode by selecting the SCI value greater than 2, and the current time synchronization of the mobile communication terminal provided from the base station is increased even if the sleep mode is increased. It is possible.

In addition, in one embodiment, the mobile communication terminal 100 may be set to a continuous sleep mode to reduce battery consumption after transmitting a call rejection period information message. At this time, the current time provided by the mobile communication terminal 100 may be performed by its own timer operation. Accordingly, the mobile communication terminal 100 can prevent unnecessary battery consumption during the call rejection period.

Then, the mobile communication terminal 100 communicates with the normal base station by processing the slot mode to the original setting as the initial setting, before the call rejection period elapses or before the call rejection release message is transmitted to the mobile communication system 200. Make this possible.

As described above, the present invention transmits an information message about a rejection period to a specific mobile communication terminal to a wired / wireless telephone of another mobile communication terminal or a wired subscriber that makes a call connection request to a specific mobile communication terminal. In addition, unnecessary loads generated in the mobile communication system can be prevented in advance due to continuous call connection requests from other mobile communication terminals or wired / wireless subscribers.

In addition, it is possible to reduce unnecessary battery consumption of the mobile communication terminal set the call rejection.

On the other hand, the present invention has been described with reference to the embodiments shown in the drawings, which are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
