It may be made in parallel, and the description thereof will be omitted since it can be understood at the level of those skilled in the art.

Next, a processing procedure of the service proposed by the present invention will be described with reference to FIG. 3.

The subscriber keeps a secure telephone number (e.g., 012-1234-5678) given through the service subscription in his or her vehicle to be exposed to the outside as a contact point. As described above, in the present invention, the subscriber does not expose the actual telephone number as an external contact address to the outside, but the user can prevent the actual telephone number as the personal information of the subscriber from being leaked by having the secure telephone number in the vehicle. In the following description, a subscriber parks a vehicle in front of a store and is described as being located somewhere else to see his or her business.

Later, the owner contact [ie caller number] placed in the vehicle via his terminal 60 to speak the mobile parking request for the vehicle of another person [ie subscriber] parked in front of the store. In step 301, the call of the calling party terminal 60 is connected to the ARS device 10 by the wired / wireless communication system (302). Here, the call number of the calling party terminal 60 is connected to the ARS device 10 which is a corresponding destination by interpreting a service number, that is, a reliable telephone number through an intelligent network (SCP) interworking on a wired / wireless communication system, which is a known technology. Since it can be understood as more specific description will be omitted.

Then, according to the control of the service server 20 (that is, service setting information stored (set, registered) in the DB 30 corresponding to the secure telephone number of the subscriber), the ARS device 10 is sent to the caller side terminal 60. The announcement (eg, 'leave a voice when the beeping sound. I will deliver it to the driver immediately') (303). Here, the control by the service server 20 may change the announcement sent to the caller-side terminal 60 according to a preset ARS transmission voice (eg, a nasty male voice), a preset called party name (eg, a driver), and the like. Can be.

Therefore, the caller through his terminal 60 'Please pull out the car in front of the store. And the like to deliver to the owner (ie, vehicle movement parking request) (304), according to the control of the service server 20, the ARS device 10 is input from the caller side terminal (60). Voice recording (305). Conventionally, when a caller calls a subscriber to talk to a subscriber, the subscriber does not receive the call immediately. Therefore, the caller waits as many times as the caller waits. By serving as a secretary and responding to the caller, the caller does not have to wait, providing the service immediateness of the service delivery.

Then, after the service server 20 voice-records the message from the caller-side terminal 60 through the ARS device 10, information about the caller-side terminal 60, that is, caller information (e.g., caller's telephone number), is recorded. [011-354-9876], the caller's voice recording data ['Please pull out the car in front of the shop soon.']) To match the safe phone number is stored in the DB (30) (306). In this way, the caller information stored in the DB 30 may be notified to the subscriber terminal 50, and may be used as caller information that can be usefully used for criminal arrest by an investigation agency after a crime occurs. For example, when the caller asks the landlord for mobile parking and lures the landlord into the vehicle to commit a crime, the caller's telephone number and the caller's voice recording data are valuable for the criminal arrest.

Thereafter, the service server 20 checks the subscriber's actual phone number (eg, 011-9864-0963) matching the secure telephone number through the DB 30 inquiry, and receives service setting information (eg, advertisement content reception). Generate a message (e.g., SMS) containing the fact that the call was sent to this subscriber (e.g., there is a recorded voice) and the reply number (e.g., the phone number of the person who left the message) (307). ).

Then, the service server 20 is connected to the message terminal (SMSC / MMSC) on the wired / wireless communication system to the terminal 50 corresponding to the actual telephone number of the subscriber, the fact that the incoming call (eg, recorded voice message) And a message (eg, SMS) including a reply number (eg, the phone number of the person who left the message) (308). Here, the message sent to the subscriber is the telephone number of the ARS device (e.g., ARS service representative number) and the destination is the telephone number of the subscriber's terminal, and the subscriber who received the message receives a call button (e.g., 'Send'). In the case of selecting, the call of the subscriber station terminal 50 is connected to the ARS device.

Accordingly, the subscriber [charging] recognizes that there is a message delivered to him through a message (for example, SMS) received by the terminal 50, and presses a call button (for example, 'Send') to listen to the recorded voice message. The call of the subscriber station terminal 50 is connected to the ARS device 10 by the wire / wireless communication system (310).

Then, according to the control of the service server 20, the ARS device 10 reproduces the corresponding caller voice recording data stored in the DB 30 ('Please pull out in front of the store.') (311). Accordingly, the subscriber [the borrower] recognizes what he or she is doing without having to make a direct call with the caller, and moves to the vehicle so that the user can park the car without contacting the caller. Also, by telling the subscriber the recorded voice of the caller, ask the other person (husband, other sturdy male, etc.) to park or move if the female or luxury car owner hears the caller's recorded voice and is suspicious. You can also go by car. As described above, in the present invention, it is possible to achieve an advantage that can be prevented in advance against the crime of a vehicle caused by calling a driver of a specific vehicle [precautionary measures for crime].

On the other hand (another example), the subscriber (the borrower) recognizes that there is a message delivered to him through a message (eg, SMS) received by the terminal 50, and does not listen to the recorded voice message or hear the recorded voice message. Call the reply number [caller's phone number 011-354-9876] included in the post-message (eg SMS) and talk to the caller (eg ask for more time for mobile parking requests, etc.) You can also do

On the other hand, the method of the present invention as described above can be written in a computer program. And the code and code segments constituting the program can be easily inferred by a computer programmer in the art. In addition, the written program is stored in a computer-readable recording medium (information storage medium), and read and executed by a computer to implement the method of the present invention.
