Abstract

PURPOSE: A destination call waiting method in a mobile communication terminal is provided to allow a calling party to listen to an announcement message to be in a waiting state, leave a voice or a character message or release a call by transmitting a previously recorded announcement message during a short response delay time period in case that a called party is not in a good situation to answer a phone call. CONSTITUTION: A controller is in a standby state for receiving a call(311). The controller determines whether a call is terminated(313). If a call is terminated, the controller determines whether a certain key is inputted from a key input unit(315). If no key is inputted, the controller transmits a ring signal informing of a call termination to a speaker, as a normal call termination process(317). If a key is inputted, the controller determines whether the inputted key is a waiting manner key(319). If the inputted key is not a waiting manner key, the controller determines whether the inputted key is a speech key(321). If the inputted is a speech key, the controller forms a speech path to the call origination party and proceeds to a call communication state(323). If the inputted key is a waiting manner key, the controller transmits a flash information message and transmits an announcement voice message indicating of setting of a destination call waiting function stored in a voice memory to the call origination party(325). The controller drives a waiting time timer according to the destination call waiting function(327). The controller determines whether a key requesting a call connection is inputted from the key input unit(329). If a key for requesting a call connection is not inputted, the controller determines whether the waiting time timer is completely driven(331). If the waiting time timer is completely driven, the controller transmits an excuse message stored in the voice memory and releases a call(333). If the call connection key is inputted, the controller resumes a delayed call(335). The controller determines whether a call release key is inputted from the key input unit(337). If the call release key is inputted, the controller releases the resumed call(339).

Description

How to wait for incoming call on mobile terminal {METHOD FOR WAITNG AN INCOMMING CALL IN WIRELESS COMMUNICATION SET}

The present invention relates to a method for waiting for an incoming call in a mobile communication terminal, and more particularly, to a method for waiting for a predetermined time when an incoming call cannot be answered immediately.

In general, when a call is received, the mobile terminal transmits a guide message provided by the network management network to the calling party when the call cannot be received. In addition, the mobile communication terminal may be set to the vibration mode in order to prevent the transmission of the ringing tone when a call is received in a public place.

As described above, the conventional mobile communication terminal only provides a method of canceling a reception sound when a response to an incoming call is not possible at all or when a response is possible. Therefore, in the conventional mobile communication terminal, when a call receiver can answer but cannot respond, for example, if a response is delayed even if it causes inconvenience to the surroundings by making a response tone in a subway station or a library, etc. In this case, the network management network regards the incoming call as unconditional and sends a guide message to the calling party. Therefore, the caller is inconvenient to hear the guidance message unconditionally, even if the called party cannot respond immediately, to record a voice message, leave a call number, or redial again later.

Accordingly, an object of the present invention is to provide a method for designating a standby state when a mobile communication terminal cannot immediately answer an incoming call.

Another object of the present invention is to provide a method for transmitting a voice message for waiting for an incoming call in a mobile communication terminal.

Another object of the present invention is to provide a method for selecting whether to wait for a call when receiving a call waiting voice message in a mobile communication terminal.

In order to achieve the above object, the present invention sends a guide message informing the calling party when an incoming call cannot be immediately answered, and resumes a delayed call when a call connection key is input after running a maximum wait time timer. It features.

Referring to FIG. 1, the controller 100 controls an overall operation of a mobile communication terminal and performs a control operation for performing a voice dialing function according to the present invention. The memory 110 may include a ROM for storing an operation program, an electrically programmable EEPROM and a RAM, and a control program for performing a call waiting function according to the present invention. And save the data. The voice memory 120 stores voice data registered to notify the call waiting function according to the present invention. In general, data stored in the voice memory 120 is data consisting of a frequency characteristic of a voice, a signal size, and the like. The voice processing unit 130 modulates the voice signal input from the microphone and converts the voice signal into voice data, and demodulates the voice data input from the RF unit 140 into the voice signal and outputs the voice through the speaker. . The RF unit 140 is controlled by the control unit 100 and transmits various data to the base station through the antenna. The key input unit 150 is composed of a plurality of numeric keys and function keys for performing various functions, and outputs key data to the controller 210 by an external operation. The key input unit 150 according to the present invention may have a separate function key for selecting a call waiting function or implement a combination of a plurality of keys. The display unit 160 is a display device such as a liquid crystal display (LCD). The display unit 160 is controlled by the controller 100 to display a state of a mobile communication terminal, a progress of a program, an alarm message, and the like.

A method of storing a voice message for notifying setting of an incoming call waiting function according to the present invention will be described with reference to FIGS. 1 and 2. In operation 210, the controller 100 determines whether a guide voice message for notifying the setting of the call waiting function input through the microphone is recorded under the voice message recording mode for notifying the setting of the call waiting function. If it is determined that the voice message indicating the setting of the incoming call waiting function is recorded, the controller 100 determines whether a recording end key is input through the key input unit 150 in step 220. If it is determined that the recording end key is input, in step 230, the controller 100 stores a voice message indicating the setting of the incoming call waiting function in the voice memory 120. Here, the guide voice message for notifying the setting of the call waiting function may be an individual guide message by recording of the user or may be a guide message provided by the network administrator.

3 is a control flowchart for waiting for a call at the called party according to the present invention.

A method of waiting for an incoming call according to the present invention will be described with reference to FIGS. In step 311, the controller 100 is in a call reception state, and in step 313, the controller 100 determines whether a call is received. If it is determined that the call is received, in step 315, the controller 100 determines whether a predetermined key is input through the key input unit 150. Here, when the call is received, the user sees a message for selecting whether to input the standby manner key displayed on the display unit 160, and presses the standby manner key when waiting for the incoming call. If it is determined that the key is not input, in step 317, the control unit 100 transmits a ring signal informing of the call reception to the speaker as a normal call incoming vehicle.

In contrast, if it is determined that a key is input, in step 319, the controller 100 determines whether the input key is a standby manner key. Here, a waiting manner key sets a function of waiting for an incoming call and sets a function of transmitting a guide voice message for waiting for an incoming call. If it is determined that the input key is not the standby manner key, in step 321, the controller 100 determines whether the input key is a call key. If it is determined that the input key is a call key, in step 323, the controller 100 performs a normal call procedure and forms a call path with the calling party to enter a call state.

On the other hand, if it is determined that the input key is a standby manner key, in step 325, the controller 100 transmits a flash information message and provides a guide voice message indicating the setting of a call waiting function stored in the voice memory 120. Send to the calling party.

The format of the Flash with information message on the call channel according to the present invention is as described in Table 1 on IS-95B.

Field Length (bits) MSG_TYPE ('00000011') 8 ACK_SEQ 3 MSG_SEQ 3 ACK_REQ One ENCRYPTION 2 Zero or more occurrences of the following record: RECORD_TYPE 8 RECORD_LEN 8 Type-specific fields 8 * RECORD_LEN RESERVED 7

The part of the message format shown in Table 1 that may include the control information of the present invention is a part related to a record type, and is a feature indicator (RECORD_TYPE: 00000010) among various record types. It is defined in the specification to be used to inform the user of these records of the supply service and the features.

Incidentally, the record contents are as described in Table 2 below.

Type-Specific Field Length (bits) FEATURE 4 RESERVED 4

By the way, the feature identifier is "Incoming call Forwarding only defined (ie 0000 / reserved 0000) only the remaining identifier is not defined, so 0001 ~ 1111 may be used for other services. By using the above message in a situation and a specific field, the present invention intends to use a waiting manner method with a counterpart.

In step 327, the controller 100 drives a waiting time timer according to the setting of the call waiting function. In step 329, the controller 100 determines whether a key for requesting call connection is input from the key input unit 150. If it is determined that the key for requesting the call connection is not input, in step 331, the controller 100 determines whether the driving of the waiting time timer according to the setting of the call waiting function is completed. If it is determined that the driving of the waiting time timer according to the setting of the call waiting function is completed, in step 333, the controller 100 transmits an apple message stored in the voice memory 120 and releases the call.

On the other hand, if it is determined that the call connection key is input, in step 335 the control unit 100 resumes the delayed call. In operation 337, the controller 100 determines whether a call release key is input from the key input unit 150. If it is determined that the call release key is input, in step 339, the controller 100 releases the resumed call.

4 is a control flowchart for waiting for a call at the calling party according to the present invention.

A method of waiting for a call at the calling party according to the present invention will be described with reference to FIGS. 1 and 4. In step 411, the control unit 100 attempts to make a call and determines whether or not the standby manner function is set by the called party with a wireless signal (flash information) transmitted through the RF unit 140 in step 413. If it is determined that the standby manner function is not set, in step 415, the controller 100 determines whether the call connection command is a wireless signal transmitted through the RF unit 140. If it is determined that the call connection command, in step 417 the control unit 100 performs a normal call connection procedure. In contrast, if it is determined that the call connection command is not, the control unit 100 performs a call release procedure in step 419.

On the other hand, if it is determined that the standby manner function is set, the controller 100 receives the standby manner guide voice message through the RF unit 140 in step 421. Here, the standby manner guide voice message is recorded by the user directly at the called terminal or is a guide message arbitrarily set by the network management network. At this time, after receiving the standby manner guide voice message, the user presses a corresponding function key to determine whether to accept or reject the standby manner function set at the called party. Then, in step 423, the control unit 100 determines whether the function of accepting the standby manner function is input through the key input unit 150 so that the standby manner function is accepted. If it is determined that the standby manner function has been rejected without being accepted, in step 425, the controller 100 performs a call connection disable procedure. In this case, the call disconnection procedure according to the rejection of the standby manner function enters a mode capable of transmitting a general voice recording or short message service or performs a call release procedure.

On the contrary, if it is determined that the standby manner function is accepted, the control unit 100 determines whether to resume a delayed call from an incoming call with a wireless signal transmitted through the RF unit 140 in step 427. If it is determined that the delayed call is to be resumed, in step 429, the controller 100 performs a normal call procedure.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention can transmit a guide message recorded during a slight response delay period to the counterpart when the immediate response when receiving a call is difficult. The other party may then listen to the announcement, wait, leave a voice or text message, or release the call. Accordingly, the present invention solves the problem of releasing a call immediately by making the call of the user mistaken for some time delay in order to reduce the noise of a call or ringing tone using a mobile communication terminal in a public place. I can solve it.
