BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a callback service method using a mobile phone, in particular, which enables a reverse call to a landline phone using a mobile phone.

In general, a call back service (CALL BACK SERVICE) is to allow the caller to hang up, and then call the caller again to continue the communication, that is, the communication service in a state that the caller does not bear the telephone communication charges In case of extended operation, it can be operated by 080 (toll-free) service.

By using the above callback service, a specific group or company uses the method in which the company bears the cost of the telephone call when the employee is out of the office and views the communication service by telephone from the outside. In other words, if you make a call to the company and enter a designated password, etc., you will confirm that the company's private exchange is an employee. In a way that allows communication, the company will bear all the costs of telephony even when traveling and traveling.

Hereinafter, a callback service scheme according to the related art will be described with reference to the accompanying drawings.

Attached to explain the prior art, Figure 1 is a functional diagram of a callback service system according to the prior art.

Referring to FIG. 1, the callback service system according to the related art is configured such that an employee 1 who communicates with an unspecified number while on the road and a plurality of users including the employee 1 connect and communicate. The public communication network (PSTN) 2 which sets the route, the private exchange (PABX) 3 connected to the public communication network 2, which is used by a group or a company itself, and the private exchange 3 Including a colleague 4 who communicates with employees within the company or communicates with an unspecified number through the public communication network 2, and an unspecified number of recipients 5 who are subscribed to the public communication network 2. It is composed.

Hereinafter, a callback service system according to the related art having the above configuration will be described in detail with reference to FIG. 1.

The private exchange 3 is an exchange provided separately for the communication of its members in an organization such as a specific organization or a company, and in addition to the general exchange function, it can adopt and operate a special function convenient for use.

When the employee (1) is working outside the company, such as outing or traveling, there is a need for communication for the company's work, but if the communication cost is a problem, the company through the public communication network (2) Connect to the private exchange (3) operated by.

For example, when the employee 1 is connected to the private exchange 3, the employee 1 inputs a specific password and a telephone number through which the employee 1 can communicate within a predetermined time or by automatic guidance. When the recognition of the back is confirmed, communication is established by hanging up the connected telephone or by waiting for a while in the state of being first connected to the private exchange 3, and then connecting with a colleague 4 working therein through the corresponding dialing.

When the employee 1 enters the corresponding password and telephone number on the private exchange 3 and hangs up the connected CALL, a call for communication to the corresponding phone number input by the employee 1 later ( CALL) is automatically connected, the employee (1) can select and call and communicate with any unspecified recipient (5) through the private exchange 3, the communication charges added are the private exchange (3) ) To bear it.

Therefore, the employee (1) has the advantage of being able to freely communicate necessary for work without worrying about the communication costs in the outlying area.

However, the callback service method according to the related art has a problem that the callback service as described above is not provided when the cellular communication system is used.

The first object of the present invention is to use a mobile phone to solve the problem that the utilization rate of the wired communication network is lowered as the mobile phone increases, and to solve the inconvenience of the mobile terminal using a flat-rate plan provided by the mobile communication provider To provide a callback service method using a mobile phone to call the other party's phone.

A second object of the present invention is to input a counterpart digit using a mobile phone, and then transmit a message corresponding to an outgoing request signal to the other landline phone so that the landline phone user checks the mobile phone number and then turns off the mobile phone through the off hook. The present invention provides a callback service method using a mobile phone that allows call and call to a mobile phone.

Callback service method using a mobile phone according to the present invention for achieving the above object,

Selecting, by the mobile phone user, a call request button after inputting counterpart digit information;

After the base station system receives the call request signal of the cellular phone, analyzing the counterpart digit information and transmitting a call request signal to a public communication network;

Transmitting, by the public telecommunication network, the call request signal to the receiving landline telephone as a caller indication message of the mobile telephone;

Checking the caller information on the landline phone and calling the landline phone user if the caller is a valid caller, and transitioning to a standby state if the caller is not a valid caller;

And when the user is off-hook by the call of the landline telephone, is automatically dialed to the cellular telephone telephone number and performs a call when the call button is selected on the cellular telephone.

Preferably, the wired telephone is characterized by comparing the caller information with a phone number stored therein and confirming that the caller information is valid caller information.

Preferably, the method further comprises the step of transitioning to a standby state if the user does not off-hook within a predetermined time when the wired telephone is called.

Hereinafter, with reference to the accompanying drawings as follows.

2 is a block diagram showing a callback service system using a mobile phone according to an embodiment of the present invention.

 Referring to FIG. 2, the cellular phone 10 performs a wireless connection in a jurisdiction service area of a base transceiver station (BTS) 21 and has a call request button for a callback service. Here, the call request button is used as the call request mode as a button that is distinguished from the call button in the normal call mode. Alternatively, the call request service number can be replaced by the call request number instead of the call request button.

As described above, when the user of the mobile telephone 10 enters the telephone number of the counterpart subscriber telephone 40 and attempts to make a call request, the originating request packet is transmitted to the base station 21.

The base station 21 provides a wireless service to the mobile phone 10, is controlled by a base station controller (BSC) 22, and analyzes an outgoing request packet transmitted from the mobile phone 10. After recognizing the transmission request message, the transmission request signal is transmitted to the public communication network (PSTN) 23 through the base station controller 22.

Here, the base station 21 and the base station controller 22 are included in a base transceiver system (BTS).

The public communication network 30 receives the callback service request signal received from the base station controller 22 and transmits the call back service (CID: Caller ID) service to the wired telephone 40.

After receiving the caller identification (CID) message, the landline telephone 40 checks the caller information and calls the landline telephone user while maintaining a wait requested caller state in the case of a valid digit. . At this time, when the landline telephone user off-hooks, the user dials using the digit of the mobile telephone 10, which is the caller's number. After calling the cellular telephone 10, the cellular telephone user presses a call button to perform a call. Done.

In other words, since the mobile phone 10 inputs the other party's landline telephone number and then presses the call request button to transmit only the call request message, the call button does not need to be pressed. If it is a number, call the landline telephone user and perform a reverse call.

3 is a flowchart illustrating a callback service method using a mobile phone according to the present invention.

Referring to FIG. 3, a user of the mobile phone 10 inputs a phone number (digit) of the other wired subscriber 40 for a callback service (S11) and selects a call request button provided in the mobile phone 10. If (S12), the transmission request signal is transmitted to the base station system 20 (S13). The call request information (callback service information), its own phone number, and the other party's phone number are transmitted to the base station system 20 in a transmission packet. Thereafter, the cellular phone 10 transitions to a call waiting state (S12a).

The base station system 20 analyzes the call request signal of the mobile phone, checks the other party's phone number if the call request signal is received, and transmits the call request signal to the public communication network 30 according to the checked phone number. Here, the public communication network 30 provides a routing service of the wired telephone.

The public communication network 30 calls the wired telephone 40 with a call request signal including a caller number (S15).

Then, the landline 40 checks whether the calling party number included in the call request signal is a valid number. To this end, the wired telephone 40 includes digit authentication and phone number storage means, and compares the phone number stored in the storage means with the call request number to perform digit authentication to determine whether it is a valid digit (S16).

As a result of digit authentication in the landline telephone 40, if there is a caller number in the storage means, it is determined to be a valid digit. do.

That is, the outgoing request call waiting state S17 is compared with the callback service valid number stored in the wired telephone 10, and when the current outgoing call request number is a valid number, the outgoing request call waiting state S17 is shifted.

At this time, when the user of the landline phone is off hook (S18), the landline phone considers the callback service as a permission and attempts to make a call request by automatically dialing the call request number (S19).

When the other party's mobile phone 10 selects the call button (S20), a call line is formed between the landline phone 40 and the mobile phone 10, and a call is made (S21). End is performed (S22, S23).

On the other hand, when the call request number is not a valid digit or the landline telephone user does not perform the off-hook within a predetermined time, the landline telephone 40 transitions to the standby state (S24).

4 is a state transition diagram of a mobile phone for the callback service of the present invention.

Referring to FIG. 4, when a mobile phone user selects and inputs a digit button 11 for a callback service, the digit button adapter 12 transmits the selected digit to the call unit 13. At this time, the communication unit 13 accumulates the input digits, and the display unit 14 displays the input digits.

At this time, when the digit input is completed, when the call request button 15 is selected, the call request button adapter 17 transmits a call request signal to the call unit 13, and thus the call unit 13 responds to the call request signal. By doing so, the origination request information including the digit is transmitted to the base station (17). After the transmission request information is transmitted to the base station, the transmission request information transitions to the transmission request waiting state (call waiting) 18.

5 is a state transition diagram of the landline telephone for the callback service of the present invention.

Referring to Figure 5, the landline telephone is in the initial idle state (Idle) 41, the general call mode is as follows. A dial tone is generated when the off hook is made in the waiting state 41 (42). When a digit is input, the dial tone is transferred to the dialing state 44. When the digit input is completed in the dialing state 44, Routing 46 is carried out via a PSTN.

In the routing state 46, if a counterpart phone is in a call state, a busy signal is generated 48, and then transitions to a please 56 or a waiting state 41, and a ringing signal state after routing. If it is generated at 50 and there is a response from the other party, it transitions to Talking 52.

In the call state 52, when the other party wakes up the phone (Remote hang up), the receiver transitions to the silent state (Silent) 54 for a while, and then transitions back to the unavailable call 56 or the waiting state 41. .

In addition, when an incoming call is generated in the waiting state 41, when the off-hook is made in the ringing state 64, the transition to the call state 52 is performed. When the off-hook is not performed, the call is disconnected and the standby state is waited. As it transitions.

On the other hand, for a callback service according to the present invention, when a request dialing call (Request dialing call) is received in the waiting state 41, the landline telephone checks the call number (58), the call number is a valid number (valid number) is checked.

If the calling number is a valid number, the mobile station switches to the wait requested caller 60 and performs auto dialing when it is off-hook from the waiting call waiting state (62). It enters the call line routing state.

However, if the calling number is not a valid number (Invalid number) or the waiting time expires (waiting timeout) in the waiting state of the calling request, the state transitions to the waiting state 41.

By providing such a callback service, the mobile phone user can call the other party's phone by adding a call request function to the mobile phone so that the mobile phone user can maximize the function of simply receiving when the service such as the flat rate or student fee expires. After that, the other party's telephone is allowed to receive the call through the reverse call.

So far, the present invention has been described with reference to the preferred embodiments, and those skilled in the art to which the present invention pertains to the detailed description of the present invention and other forms of embodiments within the essential technical scope of the present invention. Could be implemented. Here, the essential technical scope of the present invention is shown in the claims, and all differences within the equivalent range will be construed as being included in the present invention.
