Secret communication method using mobile communication terminal {Method for scramble using mobile terminal}

The present invention, by using a caller identification display (CID) service, one of the mobile communication services for the incoming call designated as 'secret call' automatically switched to the earphone call mode, allowing the called party through the earphone It relates to a secret call method using a mobile communication terminal that allows a secret call with the caller.

Caller ID (CID) service, one of the mobile communication services, is a service for preventing the invasion of communication privacy of incoming subscribers such as phone violence and indecent phone calls using anonymity. It is displayed on the subscriber's (user's) mobile communication terminal (cell phone, PDA, etc.). In other words, the caller's phone number (and name) is displayed on the called party's mobile terminal between the first ring tone and the second ring tone, and the caller's phone number is stored for the incoming call. This is a service that provides a function of storing the missed number.

Thus, the called party can know the caller's phone number (and name) before calling the caller from this CID service, and if the called party who checked the caller's phone number (and name) wants to make a secret call with the caller, By connecting the earphone to the earphone jack (Earphone Jack) provided in the mobile communication terminal as shown in Figure 1, the caller's voice (voice) is made a secret call while not being heard by others through the speaker of the mobile communication terminal.

However, in the conventional secret communication method using a mobile communication terminal, the called party must check the caller's phone number from the CID service and then manually switch to the earphone call mode to make the secret call, that is, the earphone is transferred to the mobile communication terminal. After connecting to the earphone jack, press the call button on the earphone, if the incoming call is received and the call is connected before connecting the earphone to the earphone jack and the caller immediately responds to the connected call (eg For example, if you say 'hello'), there is a problem that the caller's voice is exposed to others through the speaker of the mobile communication terminal, which is not yet switched to the earphone call mode, making it difficult for incoming subscribers.

In addition, if the called party receives a call without checking the caller's phone number (and name), the caller's voice, which requires a secret call, is exposed to the other person through the speaker of the mobile communication terminal, making it difficult for the called party. There was a problem.

If the incoming subscriber connects the mobile communication terminal to the vehicle hands-free for driving, that is, in the state in which the earphone jack of the vehicle hands-free and the earphone jack of the mobile communication terminal are connected as shown in FIG. When a call is received on the terminal and the called party connects the call unconditionally without the caller's confirmation, the caller's voice is output through the hands-free speaker of the vehicle. there was.

At this time, the incoming subscriber confirms the caller's phone number (and name) in advance from the CID service, and then determines that the caller needs a secret call to release the hands-free connection to the earphone jack of the mobile communication terminal. Then, after connecting the earphone to the earphone jack of the mobile communication terminal, and then to talk to the caller through the earphone, it is more cumbersome to make a secret call when using the vehicle hands-free, in which case there is a risk of a traffic accident. There was this.

Therefore, the present invention was created to solve the above problems, by automatically switching to the earphone call mode for an incoming call designated as a secret call using a caller information display (CID) service, one of the mobile communication services, Its purpose is to provide a secret communication method using a mobile communication terminal that allows a secret call with a desired party without fear of invasion of privacy of the called party.

Figure 4 shows the flow of a preferred embodiment of a secret call method using a mobile communication terminal according to the present invention, hereinafter will be described in detail with respect to the secret call method of Figure 4 according to the present invention with reference to the detailed configuration of FIG. do.

First, a user may register and store a phone number of a lover or a friend by using a 'phone book' function in the 'menu' provided on the mobile communication terminal 100. For this purpose, the user may register the name of the counterpart (sender) to be registered. And a phone number is input through the keypad 10, the name and phone number entered in this way is stored in the flash memory 20 in association with the 'phone book' function, the storage form is shown in FIG. As illustrated.

As such, when the caller's name and phone number, i.e., when the caller information is registered or stored in association with the 'Phonebook' function, or when the registration is stored, the user can specify a caller's phone number for which a 'secret call' is desired. Using the 'menu' key on the keypad 10 to designate the caller's telephone number that wants to 'secret call', the station unit 40 is the caller's telephone number designated as 'secret call' as shown in FIG. By making a specific indication (e.g., 'V') indicating that the call is designated as a 'secret call' in association with the caller's phone number (and name), Make it easy to know the designated caller's phone number.

As such, the user designates the caller's telephone number that the user wants to 'secret call', and the user is the called subscriber subscribed to the caller ID (CID) service, which is one of the mobile communication services. When the call is received (S10) the station unit 40 checks the caller's telephone number for the call received through the wireless receiving unit 71, when the caller's call connection request, the base station is the caller through the nearby exchange Since the telephone number is transmitted to the mobile communication terminal 100, the station unit 40 can easily check the caller's telephone number for the incoming call.

The station unit 40 checks whether the confirmed caller phone number is pre-registered and stored in the flash memory 20. If the registered caller number is already registered and stored, the station 40 is pre-registered and stored in association with the confirmed caller phone number. The caller's name is displayed on the LCD 30 through the LCD driver 31, and the station unit 40 transmits a ringing ring tone designated on the mobile communication terminal 100 to the a terminal of the switch 62. By outputting to the speaker provided in the mobile communication terminal 100 through (S11), the incoming subscriber can recognize that the call has been received.

In addition, the station unit 40 checks whether the identified caller's telephone number is designated as 'secret call' from the flash memory 20 (S12), and is a telephone number designated as 'secret call' (S20). ) When the incoming subscriber connects the incoming call, that is, recognizes it as a 'secret call', connects the earphone to the earphone jack of the mobile communication terminal 100, and then presses the 'call' button provided in the earphone, or When the call is connected by pressing a button provided on the keypad 10, the station unit 40 automatically switches to the earphone call mode to perform an operation according to the earphone call mode (S21), that is, the station unit. 40 controls the switches 62 and 64 to be connected to the b terminal, thereby allowing the called subscriber to 'secret call' with the caller through the earphone, which will be described in more detail. And the like.

First, the wireless receiver 71 converts the received voice signal into a baseband signal, and the station unit 40 restores the converted voice signal back to voice data according to a protocol, and converts the received voice signal into voice data. 60). The call codec 60 converts the restored compressed voice data into an analog voice signal, and the converted analog voice signal is amplified by the output amplifier 61 to be connected to a speaker (b) through the b terminal of the switch 62. It is output to the earphone jack instead of Sp).

On the other hand, when the called party confirms that the caller is designated as a 'secret call' from the caller information (caller's phone number and name) displayed on the LCD 30, the called party is called from the mobile communication terminal 100. The earphone is connected to the earphone jack to listen to the caller's voice, and as the earphone is switched to the call mode, the switch 64 is a voice signal input through the earphone jack, not the microphone provided on the mobile communication terminal 100. That is, the voice signal input through the microphone provided in the earphone is output to the input amplifier 63.

Accordingly, the incoming subscriber's voice is signaled through the input amplifier 63, the codec 60, and the station unit 40, and then applied to the wireless transmitter 70, whereby the incoming subscriber's voice is transferred to the mobile communication network (e.g., For example, through a CDMA mobile communication network.

In the above embodiment, if the confirmed caller's telephone number is registered and stored in the flash memory 20, but the caller's name is not registered and stored in the flash memory 20, the station unit ( 40 outputs and displays only the caller's telephone number on the LCD 30. If the confirmed caller's telephone number is not the designated telephone number, the station unit 40 switches the switch 62. , 64) is connected to the terminal a, the caller's voice is a speaker, and the general subscriber mode that the incoming subscriber sends a voice (voice) input through the microphone provided in the mobile communication terminal 100 to the caller By performing (S22), a general call is made between the caller who is connected and the called party, not the 'secret call'.

6 is a flow chart illustrating another embodiment of the secret communication method using the mobile communication terminal according to the present invention. Hereinafter, the secret communication method of FIG. 6 according to the present invention will be described in detail with reference to the detailed configuration of FIG. do.

In the embodiment of Fig. 6, when designating the caller's telephone number for the 'secret call' of the called party, the ring tone may be specified separately from the ringtone for the general call. For example, the called party can designate the ringtone for the general call as 'Jingle Bell' and the ringtone for the 'secret call' as 'Minuet'. The station unit 40 stores the type of the ringing tone specified for the 'secret call' as described above, and also relates to the caller's phone number (and name) as shown in FIG. 7 for the caller's phone number designated as the 'secret call'. By making a specific indication (eg, '♪') indicating that the call is designated as a secret call, it is easy to see that the called party has designated the 'secret call' by specifying the ring tone.

As such, when the ring tone is designated for 'secret call', one ring tone may be specified so that the caller's phone number designated as 'secret call' may be distinguished from the general call, not 'secret call', but the caller's call designated as 'secret call' You can also specify different ringtones for the number.For example, caller ID1 (for example, 011-9901-XXXX) designated as 'secret call' is set to 'minuet' and 'secret call' Caller ID 2 (e.g. 011-231-XXXX) is designated as 'For You' and caller number 3 (e.g. 031-612) specified as 'Secret Call'. -XXXX) can be variously designated according to the choice of the called subscriber, such as designating the ringtone as 'waltz'.

In this state, when a call is received (S30), the station unit 40 outputs caller information on the LCD 30 as described above (S31), and the caller's telephone number for the incoming call is 'secret'. In the case of the designated phone number (S32, S40), the ringtone for the 'secret call' designated by the called subscriber is output through the speaker provided in the mobile communication terminal 100 (S41) as a called subscriber. Even if you only hear the ringtone, you can see that the incoming call is a call that requires a 'secret call'.

In this state, when the incoming subscriber connects the incoming call as described above, the station unit 40 automatically switches to the earphone call mode to perform an operation according to the earphone call mode (S42). The station unit 40 controls the switches 62 and 64 to be connected to the b terminal, thereby allowing the called party to 'secret call' the caller through the earphone.

In the above embodiment, if the confirmed caller phone number is not the phone number designated as 'secret call', the station unit 40 performs the general call mode as described above (S43).

The above embodiments so far have described an example in which a called party specifies a 'secret call' by designating a caller who wishes to 'secret call', whereas the caller requests a 'secret call' regardless of the intended recipient's intention. To this end, the caller may specify a specific key designated for the 'secret call', which is distinguished from the general call key when the recipient's telephone number (for example, 011-123-XXXX) is entered for a call connection on the communication terminal. Press (#, ＊) first, that is, press # ＊ 011123XXXX.

As such, when the caller presses a predetermined specific key for a secret call, the exchange receiving the information on the predetermined specific key through the base station transmits it back to the called subscriber's mobile communication terminal 100, thereby transmitting the caller. The call requested by the call subscriber is recognized as a call requiring a secret call in the mobile communication terminal 100 of the called party.

On the other hand, when the station unit 40 of the mobile communication terminal 100 receives information on a specific key (#, *) designated for the 'secret call' together with the caller's telephone number when the call is received, the station The unit 40 recognizes that the incoming call is a call requiring a 'secret call' from the received information on the specific key, and as described above, the called party distinguishes the ring tone designated by the called subscriber for the 'secret call'. Output through, and when the incoming subscriber connects the incoming call automatically switches to the earphone call mode, allowing the incoming subscriber to 'secret call' with the caller through the earphone.

In the above embodiment, the exchange receives the specific incoming signal distinct from the general incoming signal for the secret call instead of the information on the received specific key so that the call requested by the caller is recognized as a call requiring a secret call. It may be transmitted to the subscriber's mobile communication terminal 100. In this case, when the station unit 40 receives a specific incoming signal distinct from the general incoming signal when the call is received, it is recognized as a call requiring a secret call. As described above, the designated ringing tone for 'secret call' is output through the speaker and then automatically switched to the earphone call mode so that the 'secret call' is made through the earphone.

In this case, if the incoming call is not a call requiring 'secret call', the station unit 40 performs the general call mode as described above.

In addition, in consideration of a vehicle hands-free, when the mobile terminal 100 is provided with a separate jack (speaker jack) which is distinct from the earphone jack generally provided in the mobile terminal, the user typically uses the hands-free earphone jack when driving. By connecting with a speaker jack separately provided in the mobile communication terminal 100, when a call is received on the mobile communication terminal 100, the incoming subscriber to talk to the caller while listening to the caller's voice through the hands-free speaker, ' When the call designated as 'secret call' is received, the station unit 40 automatically switches to the earphone call mode so that the called party can talk to the caller through the earphone connected to the earphone jack of the mobile communication terminal 100. Disconnect the hands-free earphone jack and the mobile communication terminal 100 one by one for 'secret call' It allows you to make 'secret calls' quickly and safely without any hassle.

The above-described preferred embodiments of the present invention are disclosed for purposes of illustration, and those skilled in the art can improve, change, and substitute various other embodiments within the technical spirit and scope of the present invention disclosed in the appended claims below. Or addition may be possible.

Secret communication method using a mobile communication terminal according to the present invention made as described above, the caller's phone number designated by the called party subscribed to the caller information display service (CID service) designated as 'secret call' automatically calls the earphones when the call is received. By switching to the mode, the user makes a secret call without fear of invading the privacy of the called party, and if the incoming call is a call that requires a secret call, the incoming caller who has been designated for the call requiring the secret call is output. Is a very useful and convenient invention that can quickly and accurately recognize that a call requiring a secret call has been received.
