The present invention relates to an apparatus and a method of receiving a rejection of a mobile communication terminal capable of performing selective rejection according to a telephone number received at a mobile terminal. More particularly, the present invention relates to a voice message transmission, which is a problem of the conventionally presented method. The present invention relates to an apparatus and a method of receiving a rejection of a mobile communication terminal, which can be implemented to improve an imposition of a call charge, a discomfort of a counterpart, and an inefficiency due to a uniform rejection.

In general, when a mobile terminal rejects a reception by using a terminal function, when the incoming signal rings to the terminal, the user rejects the reception by pressing a specific key of the terminal before a predetermined time elapses. Has been introduced, such as to register a service or to unsubscribe at a specific time for a specific group consisting of a specific number or multiple phone numbers in a terminal.

In these methods, the caller must check the calling number every time to reject the call and select a specific key, or the registration procedure for the call-back phone number is difficult, and more fundamentally, it is not the standard protocol that is used. The standard protocol enacted the constraints of changing functions in both the terminal and the switching system.

As a method of responding to the calling terminal when the called terminal rejects the reception, a method of transmitting an auto-response message composed of voice or text, and providing a ringing sound to the calling terminal while silently ringing the ringtone of the called terminal ( Or lamp), a method of transmitting a call termination signal, or the like may be used.

In case of sending an auto-reply message, a caller is charged. In the United States, call charges are also charged to the called party. The method of changing the ringing tone of the called terminal to silent (or ramp) while continuously supplying the ringing sound to the calling terminal waits for the caller to wait, and the channel is wasted in the meantime. In addition, when a call termination signal is transmitted, a ring back tone transmitted to the caller is interrupted, which may cause the caller to be mistaken for a sudden communication error.

In addition, there is a method of maintaining a non-active state in a slightly different form from the above method, which can be seen through FIG. 1.

1 illustrates a flow of entry and release of an inactive state of a terminal according to the prior art.

First, it is assumed that "status_flag" is arbitrarily set as a parameter representing the activation deactivation state of the terminal. When status_flag is "0", it is assumed that the terminal is inactive, and when status_flag is "1", it is indicated that the terminal is activated. do.

Initially, the status parameter status_flag is set to "1", and is initially set as not entered into the inactive state (S101).

In the initial state, it is checked whether a key for requesting entry into the inactive state is input (S102). When the inactivation request key is input, the status parameter status_flag is set to "0", and the power down registration signal is transmitted to the base station. It transmits and enters into an inactive state (S103). When any terminal enters the inactive state, the base station blocks all call requests for the terminal, and thus the terminal does not receive any call request signal, which is until the activation request key is input again. Continues.

That is, periodically check whether the activation request key is input (S105), when the activation request key is input, reset the status parameter status_flag to "1" and transmit a power-up registration signal to the base station. Return to the active state (S107).

In the state in which the deactivation request key is not input, periodically checking whether a call request signal is received (S104), and when a call request signal is received, request that the incoming terminal ring an incoming ring, and the user opens a folder or calls The call is started by selecting the button (S106). When the call is completed (S108), the process returns to the initial stage and checks whether the deactivation request key is input (S102).

As described above, the method shown in FIG. 1 is a method of entering a deactivated state by operating an input key of a terminal when a call request signal is received, rather than entering a deactivated state, and rejecting all calls. . Therefore, when using this method, since the receiving terminal is kept in an inactive state, the system including the base station controller and the base station blocks all calls without transmitting any signal to the receiving terminal. Therefore, this method cannot be used if you want to reject only certain call requests. In addition, in order to cancel the deactivation state and return to the receivable state, it is inconvenient to manually operate the input key again.

The present invention is an apparatus and method for receiving a rejection of a mobile communication terminal, which enables an effective rejection by implementing a user to select a manual or automatic mode in setting and releasing a deactivation state of a terminal in a rejection of a mobile communication terminal.

Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to the drawings.

2 illustrates a logical block configuration of a mobile terminal for performing the rejection according to the present invention.

The mobile terminal referred to in the present invention includes a cellular telephone, a personal communication system (PCS) telephone, a personal data assistant (PDA), and an international mobile communication-2000 (IMT2000) terminal. Note that it is used in the sense of inclusion.

The controller 100 performs overall operations of the mobile terminal, that is, processes and controls for voice call and data communication. In particular, the present invention compares the telephone number stored in the reject list and the calling number of the incoming call according to whether the terminal is inactive or not and whether the terminal is inactive or not, and performs the rejection procedure. Play a role.

The display unit 111 displays status information generated during the operation of the mobile terminal, a limited number of characters, a large amount of video and still images, and the like. A liquid crystal display (LCD) is generally used for the display unit 111, and recently, an organic EL or the like is also used.

The key input unit 112 includes a number of 0-9 keys, a plurality of function keys such as a menu, a text transmission key, a call, and an end key, and provides the control unit 100 with key input data corresponding to a key selected by a user. It plays a role. In the case of the deactivation setting and / or release button of the terminal according to the present invention, and the selection button of the manual and automatic rejection mode, it can be set differently depending on how to implement the function of the terminal, for the purpose of creating an automatic rejection list The menu may also be set in a variety of ways.

The codec (Coder-Decoder) 150, and the receiver 161 and the transmitter 162 connected to the codec 150 are voice input / output blocks used for telephone calls and voice recording. The codec 150 converts the PCM data provided from the controller 100 into an analog voice signal and transmits the same through the talker 162. The codec 150 converts the voice signal received through the receiver 161 into PCM data. 100).

The RF transmitter 131 increases the frequency of the baseband signal from the signal processor 120 and outputs the frequency through the antenna, and the RF receiver 132 lowers the RF signal received through the antenna to the signal processor 120. do.

The signal processor 120 processes baseband signals transmitted and received between the RF transmitter 131, the RF receiver 132, and the controller 100. That is, in case of transmission, channel coding and spreading of data to be transmitted are performed, and in case of reception, despreading and channel decoding are performed.

On the other hand, the ROM (141) stores the microcode and various reference data of a program for processing and control of the control unit 100. The RAM 142 is a working memory of the controller 100, and stores temporary data generated while performing various programs. Flash RAM 143 stores various updatable storage data such as a phone book. In view of such characteristics, the flash RAM 143 may be a form of the most preferred embodiment of the memory unit for storing the automatic rejection list used in the present invention.

3 shows a call processing procedure for an incoming call of a terminal according to the present invention.

A call originating from a PSTN or a counterpart's mobile terminal must go through a complex process of several steps until it reaches the called party's mobile terminal through the mobile communication network. Since the present invention relates to a call rejection, FIG. 3 illustrates only a call processing procedure when a mobile terminal receives a call regardless of which call origination is made.

The terminal that receives the paging from the base station, the last end of the mobile communication network, responds to the paging message. After the forward traffic and the reverse traffic channel is formed, the terminal receives the alert with information including the calling party number and the ringing signal information from the base station.

In this case, in general, the user enters a call state with the calling party by opening a folder or selecting a call button. When the call is over, the call is terminated by closing the folder or selecting the end button to send a disconnect signal to the base station or receiving a release command signal from the other party.

However, in the present invention, a traffic channel is formed between the receiving terminal and the base station based on the existing standard protocol, and when the base station waits for the terminal's response (Waiting for MS Answer Sub-State), the called terminal receives the calling number. Determine if the number is stored in the reject list. As a result of the determination, when the calling number is stored in the reject list of the called terminal, the call is rejected by automatically or manually transmitting a power down registration signal to the base station according to the setting at the called terminal.

When a registration accepted order signal is received from the base station or an alert signal does not reach for a predetermined time or more, a power up registration signal is transmitted to the base station to return to a normal state.

The above procedure will be described in more detail with reference to FIG. 3.

The base station (BTS) 300 of the cell where the receiving terminal 200 is located transmits a page message (General Page Message) wirelessly through a paging channel to call the destination mobile terminal 200 (S301). The called terminal 200 observes the call channel, recognizes the call of the base station 300 (S302), and transmits a page response message (Page Response Message) to the base station 300 through the access channel (S303). The base station 300 acquires initial synchronization through a preamble (S304), and provides a channel frequency, a Walsh code number, etc. to the called terminal through a channel assignment message (S305). . The mobile terminal receiving this converts the reception mode to the call channel (S306).

When the base station transmits null data to the called terminal through the forward traffic channel (S307), the called terminal transmits a preamble signal to the base station through the reverse traffic channel (S308). The base station acquires initial synchronization of the reverse traffic channel (S309), and transmits the acquisition to the destination terminal (S310). The called terminal 200 transmits null data to the base station through the reverse traffic channel (S311). When the base station 300 transmits the desired call type to the destination terminal through the service option message (S312), the destination terminal allocates resources according to the option (S313). In addition, when the base station 300 informs the call connection to the destination terminal through the service connection message (S314), the destination terminal starts the call channel demodulation according to the option (S315). When the called terminal also notifies the call connection through the service connection message, the base station instructs the called terminal to ring the incoming call through an alert information (Alert Information) message (S317). The receiving terminal receiving the Alert signal of the base station rings the incoming bell (S318), and responds to the base station through a connection order (Connection Order) (S319). From this point, a voice call channel is formed between the terminal 200 and the base station 300 and a call is made between the caller and the receiver.

The part of the procedure of FIG. 3 that is differently applied in the present invention is a procedure mainly after step S317. In step S317, the alert signal is automatically entered into the automatic rejection step according to whether the user's terminal state is set or the manual rejection or call state is entered according to the user's selection according to the calling number. A more detailed procedure related to the core of the present invention will be described with reference to FIG.

4 illustrates a procedure of entering and releasing a deactivation state of a terminal and a reception flow according to the present invention.

In the embodiment of Fig. 4, auto_reject is used as a parameter representing the auto-rejection state. auto_reject is a parameter indicating setting or canceling of the automatic rejection mode, and initially sets the value to "0" to indicate that the automatic rejection canceling state is performed (S401).

In the initial state, the automatic rejection setting key is input or the automatic rejection release key is checked, and when a signal for requesting a call is received, a full-fledged function is performed. That is, it is checked whether a key for automatic rejection setting is input (S402). When the automatic rejection setting key is input, the auto_reject parameter is set to "1", and the automatic rejection state is displayed (S403). Also, it is checked whether a key for automatic rejection is input (S404), and the auto_reject parameter is set to "0", and in this case, the automatic rejection release state is displayed (S405).

As described above, the terminal stays in the waiting state while checking whether the call request signal is received (S406), and when there is a call request for the corresponding terminal, the terminal changes the operating state according to whether or not it is in the automatic rejection state (S407).

If the terminal is set to the automatic rejection state, it is checked whether a call request from the sender in the automatic rejection list (S408), and immediately transmits a power-down registration signal (S410).

"Power-down Registration" means registration performed to notify the system when the wireless communication terminal is powered off. That is, the purpose of power-down registration is to notify the system that the terminal is powered off, and the system that receives this fact does not call the terminal because it recognizes that a call cannot be connected to the terminal when an incoming call request is received. It is not. When the user requests to turn off the power, the terminal completes the power down registration procedure by sending a registration message including a corresponding "REG_TYPE" field through an uplink channel and receiving a response message from the base station. That is, the system receiving the power down registration signal recognizes that the corresponding terminal is powered off, and transmits the corresponding comment or tone to the calling party.

It is desirable that the reception should be decided by one called unit and it is impossible to predict how fast the next incoming call is made after the rejection of one calling terminal. Not. Therefore, when the UE receives a registration accepted order signal from the base station or the alert signal from the base station is interrupted for a predetermined time (S411), it means that it is ready to receive another call again. Transmit to the base station (S412). Thereafter, the terminal performs automatic or manual rejection through a new configuration or performs a normal call reception procedure without rejection.

"Power-up Registration" means a registration performed to notify a mobile communication system including a base station when a wireless communication terminal is powered on. That is, the purpose of "power-up registration" by the IS-96A is to inform the system that the power of the wireless communication terminal is ON, to inform the system which cell the terminal is currently located in. The system may call a terminal and connect a call when an incoming call request sent to the terminal is received only when the current location of the terminal is known.

On the other hand, if the terminal is set to the manual rejection state instead of the automatic rejection state in step S407 of the operation flow of Figure 4 or the corresponding call request is not a call request from the sender in the automatic reject list in step S409, the terminal Receives an Alert signal from the base station, rings an incoming ring, notifies that a reception request has been received, and waits for a user's acceptance / deny response (S409).

If the user checks the calling number and does not want to call, manually select the key set to reject the call.If the user wants to call the calling party with the called call number, select the key for accepting the call. (S420).

When the user selects a key to reject the reception, the terminal transmits a power down registration signal to the base station (S421), when a registration permission signal is received from the base station or the alert signal from the base station is stopped for a predetermined time (S422) In step S423, the power-up registration signal is transmitted to the base station.

On the other hand, if the user wants to call, the procedure is almost the same as the general incoming procedure. That is, at the same time as selecting the call acceptance button, the terminal transmits a call (Connection Order) signal to the base station, and initiates a call with the other party (S430). The terminal waits for the call to be completed, returns to the initial state, and waits for the next incoming call (S431).

According to the present invention, the user of the called terminal does not send an auto-answer message when the user does not want to receive the call, and does not incur a call charge. Less, and if the ringback tone is interrupted by a sudden disconnect, the caller will recognize it as a call error and try to resend so that it doesn't waste resources. In addition, there is an advantage to facilitate the user in that it is possible to selectively reject by the reject list rather than unconditional rejection.
