Abstract

PURPOSE: A method for alerting a receiver response is provided to inform an originator that a receiver approves a call by using a vibration or a melody, if the receiver answers the phone after the originator calls the receiver, thereby removing an inconvenience of the originator holding the phone on the originator's ear until the receiver answers the phone. CONSTITUTION: An originating mobile communication terminal decides whether a call origination attempt is produced in a standby state(210,212). If so, the mobile communication terminal transmits a calling message(214), and decides whether an information alert message is received to ring a ringback tone signal(216). If so, the mobile communication terminal generates a ringback tone(218), and decides whether an information alert message showing a tone off state is received(220). If so, the mobile communication terminal informs a user of the message by a vibration or a bell sound(222). The mobile communication terminal turns off the ringback tone signal(224), and supplies a call(226).

Description

{Method for alerting that the called has answered the call}

The present invention relates to a caller response notification method, and more particularly, to a caller response notification method for notifying a caller of a caller by vibrating or melody when a caller receives a call after the caller makes a call.

In general, in the case of a wired telephone interworking with a public switched telephone network (PSTN), when a communication channel is established by a communication protocol, a ringing tone signal (ring signal, 75Vrms, 16Hz) is transmitted from the exchange to the called party, and the calling tone is transmitted to the caller. Signal (Linbeckton signal, 75Vrms, 400Hz) is transmitted.

At this time, the dial tone signal is provided to the caller through the handset speaker of the caller's telephone and the ring tone signal is provided through the ringer of the called party's telephone. In general, the ringer provides various ring tones (eg, simple music such as melody) so that the called party can call the telephone. It allows you to select the ring tone you want.

Currently, even in the case of widely used mobile communication terminals, the base station transmits an Alert with information message for ringing to the called party's terminal when the called terminal is similar to the wired telephone. Let it play.

On the other hand, in performing the terminating process, an information alarm for executing a call processing such as an information alarm message to a terminating terminal in a mobile communication network and generating a ring back tone for the originating terminal. Sending a message tells the sender that the originating process is currently running.

The call signal is continuously supplied until the called party answers. This call waiting time is unnecessary from the caller's point of view.

In particular, when the called party is a subscriber of the mobile communication network, the called party often does not recognize the dialing tone due to the surrounding noise, and the incoming call processing does not proceed smoothly due to the deterioration of the communication environment. Failure to do so frequently occurs.

In this case, the caller is in the call waiting state for a long time while listening to the above-mentioned ring tone. It is estimated that the waiting time until the called party answers after the caller executes the call is typically 8 to 12 seconds.

Accordingly, the present invention has been made to solve the above problems, and provides a caller response notification method to notify the caller of the caller to vibrate or melody when the caller receives a call after the caller makes a call For that purpose.

According to the present invention for achieving the above object, the calling mobile terminal generates a ringback tone signal when an information alarm message for transmitting a call message and ringing a ringback tone signal is received when a call origination attempt is made in a standby state. Making a first step; A second step of notifying the incoming call using the vibration mode when the toneoff information alarm message is received after the first step; And after the second step, a third step of turning off the ringback tone signal and providing a call.

In addition, the present invention, the first mobile communication terminal is a first step of transmitting a call message, if there is a call origination in the standby state, and generates a ringback tone signal when received an information alarm message to ring the ringback tone signal; A second step of notifying an incoming call using a ring tone after receiving the tone off information alarm message after the first step; And after the second step, a third step of turning off the ringback tone signal and providing a call.

Now, with reference to the drawings of Figure 1 will be described in detail a preferred embodiment of the present invention.

1 is a block diagram showing a network configuration of a mobile communication system to which the present invention is applied, and the basic concept of the present invention will be described.

In the mobile communication network of FIG. 1, a plurality of exchangers EX: EX1 to EXn are provided for switching the call path.

Each exchange EX is then coupled to each other via an E1 link. A plurality of base station controllers (BC: BC1 to BCn) are coupled to each switch EX, and a plurality of base stations BS to the base station controller BC are each BS1 to BSn. ) Will be combined.

In addition, each base station (BS) is coupled to a plurality of terminals (MS) through the airwave transmission network, wherein the base station (BS) and the terminal (MS) is combined by a TDMA or CDMA method.

In addition, each switch EX is combined with a public switched telephone network (PSTN), an integrated services digital network (ISDN), or another mobile communication network through a predetermined gateway (G1 to G3), and interworking (IWF). It is coupled to the Internet through a function (I1) and a WAP gateway (G4).

In the above configuration, when a communication subscriber attempts to make a call through a normal registration terminal (MS), that is, the subscriber inputs the other party's telephone number (called number) to which the communication subscriber wants to communicate by operating the number key of the terminal MS. After pressing the 'SEND' key, the corresponding terminal number, that is, the calling number and the called number are transmitted to the exchange EX through the base station BS and the base station controller BC.

Subsequently, the exchange EX interprets the received called number and executes a call connection to provide a communication function to the calling terminal.

That is, in the case of a subscriber in a mobile communication network having the same destination number, the exchange EX reads out routing information through a home location register (HLR) (not shown), and then, based on this, the exchange EX reads out the routing information. By executing the circuit connection process, the communication function for the caller is provided.

If the called number is another service network subscriber, the communication function is provided by executing line connection processing with the other service network through predetermined gateways G1 to G4.

On the other hand, in performing the terminating process, in the mobile communication network, the call processing is performed by transmitting an Alert with Information message for ringing the terminating terminal.

The base station transmits an Alert with Information message to ring the ring back tone to the calling party, and then sends an Alert with Information message to ring the ring back tone. The originating terminal that receives the Rx) generates a ring back tone.

At this time, when the called party answers the call, the calling base station transmits a tone off information alarm message from the calling base station to the calling terminal, and the called terminal receiving the tone off information alarm message is called with a vibration or a ring tone. Informs you that you have received.

Then, the called terminal stops the ringback tone signal and provides a state in which a call can be made.

FIG. 2 is a data flow diagram illustrating each operation during call and processing of a mobile communication terminal and a base station to which the present invention is applied and data flow according thereto.

As shown in FIG. 2, first, the base station continuously transmits a pilot channel to all supported frequency assignments (FA) and continuously transmits a synchronization channel message to a CDMA channel (S10).

The system setting is performed by the internal operation of the mobile station. The first layer of the mobile station (which refers to the first layer of the three-layer protocol for transmitting GSM information, where GSM means 'Global System for Mobile communication') is a pilot channel. It monitors the synchronization channel and receives the system setting message including the connection parameter confirmation message.

Subsequently, the calling mobile station transmits a calling message to the access channel through the connection attempt (for example, the caller enters the called party's mobile number and presses the 'SEND' key) (S20). Receive a call message from the base station to the call channel (S30).

If it is confirmed that the message of the call matching result is received through the current call channel, the mobile station transmits a call response message to the access channel through the access attempt to the base station (S40).

When the base station receives the call response message, the base station processes the areas of the message and selects a possible communication channel to transmit a channel assignment message to the called mobile station and the calling mobile station through the calling channel. At the same time, the base station starts to transmit null call channel data (S50).

Each mobile station receives a predetermined number of good frames, performs an acknowledgment procedure, and transmits a reverse call channel preamble to the base station (S60).

The base station, which has acquired the reverse call channel by receiving the preamble, transmits base station confirmation command data to each mobile station (S70), and each mobile station that has received this retransmits the mobile station confirmation command data and the null call channel data (S80).

After confirming the mobile station, the base station transmits an information alarm message for ringing a ringback tone signal to the calling mobile station (S90), and transmits an information alarm message for ringing to the called mobile station (S100).

At this time, the calling mobile station receiving the information alarm message to ring the ringback tone signal generates a ringback tone, and the called terminal receiving the information alarm message to ring the ring tone generates music or other predetermined ring tone. .

Upon receiving a call response instruction (for example, opening the cover of the mobile phone and hooking off) when the user hears the signal alarm, the called mobile station transmits the connection command data to the base station (S110), and the base station sends the tone off information alarm to the calling mobile station. The message is sent to stop the ringback tone (S120), and the base station connects the traffic channel between the calling mobile station and the called mobile station to transition to a call state (S130).

On the other hand, the calling mobile communication terminal receiving the tone off information alarm message informs that the called party has received the call with vibration or melody before stopping the ringback tone signal.

3 is an internal block diagram of a mobile communication terminal having a called party call approval notification function according to the present invention.

Referring to FIG. 3, the controller 100 controls the overall operation of the terminal and generates a ringback tone when an alarm information message for ringing the ringback tone signal is received from the base station.

And, if the control unit 100 receives an information alarm message notifying the tone off from the base station notifies the fact that the called party received the call with a vibration or ring tone.

The memory 130 is composed of a ROM for storing an operating program, an electrically programmable EEPROM, and a RAM.

The display unit 110 visually displays the overall state of the terminal and the progress state of the program under the control of the controller 100. This is usually implemented by using a liquid crystal display device.

The key input unit 120 includes a plurality of numeric keys and function keys for performing various functions as a keypad. In the implementation of the present invention, the user inputs a key on the keypad to vibrate as a means for notifying the incoming call. Select and specify whether to make a ringtone.

The key input unit 120 performs a desired operation by the user and transfers the key data generated accordingly to the control unit 100.

The RF unit 140 up-converts the signal input from the baseband processor 150 under the control of the controller 100 and wirelessly outputs it to the base station 400 via the antenna 170, or The received signal received through the antenna 170 is down-converted and output to the baseband processor 150 to perform the corresponding signal processing.

In this case, the baseband processor 150 converts the signal input from the RF unit 140 into a baseband and a digital signal and outputs the signal to the controller 100. The controller 100 performs channel demodulation and decoding operations on the digital signal output from the baseband processor 150.

The controller 100 outputs the voice data output from the baseband processor 150 to the voice processor 160. The voice processor 160 converts the voice data into a voice signal. The voice processor 160 outputs the voice data to the speaker.

The voice processing unit 160 converts the user's voice signal output from the microphone into voice data and outputs the voice signal to the controller 100. The controller 100 wirelessly outputs the voice data to the service base station via the baseband unit 150, the RF unit 140, and the antenna 170.

The vibrator 190 informs that the called party has received the call due to vibration when an information alarm message for notifying the toneoff is received from the base station under the control of the controller 100.

4 is a flowchart illustrating a method for calling a called party according to an embodiment of the present invention.

Referring to the figure, the calling mobile terminal determines whether there is a call origination attempt in the standby state (steps 210 and 212).

Then, the calling mobile communication terminal transmits a call message if there is a call origination attempt in the waiting state (step S214), and determines whether an information alarm message for ringing the ringback tone signal has been received (step S216).

As a result of the determination, when the information alarm message for ringing the ring back tone signal is received, a ring back tone is generated (step S218), and it is determined whether an information alarm message for notifying the tone off has been received (step S220).

As a result of the determination, when the information alarm message indicating the tone off is received, the call is notified by the vibration or the ring tone (step S222).

Thereafter, the ringback tone signal is turned off (step S224), and a call is provided (step S226).
