FIG. 3 illustrates a process in which a user terminal processes the inter-idle network after leaving the smart school.

Referring to FIG. 3, first, the user terminal 20 checks whether an excitation signal is received from the access point 10 (S100). When the excitation signal is received from the access point 10, the user terminal 20 transmits the first signal in response to the excitation signal (S102).

Here, the excitation signal may be a Wi-Fi beacon signal when the user terminal 20 and the access point 10 are connected by Wi-Fi communication, and the first signal may be a Wi-Fi beacon signal, 20). ≪ / RTI >

If the user terminal 20 transmits the first signal or if the excitation signal is not received from the access point 10, it is confirmed whether an excitation signal within a predetermined time is received (S104).

That is, if an excitation signal is received within a predetermined time from the reception of the excitation signal, the user terminal 20 transmits the first signal in response to the excitation signal. Otherwise, the user terminal 20 broadcasts the second signal (S106).

Here, if the user terminal 20 forms a network with a peripheral terminal through Bluetooth communication, the second signal may be a Bluetooth beacon signal.

After the user terminal 20 broadcasts the second signal to the peripheral terminal, it checks whether a response signal for the second signal is received from the peripheral terminal (S108).

When a response signal to the second signal is received from the surrounding terminal, the user terminal 20 forms a network with the peripheral terminal that transmitted the response signal (S110). If a response signal to the second signal is not received from the neighboring terminal, the user terminal 20 transmits the second signal again to attempt to form a network with the neighboring terminal.

FIG. 4 illustrates a process performed by a user terminal after network formation.

Referring to FIG. 4, the user terminal 20 receives identification information of a peripheral terminal from a peripheral terminal through a network (S112). The identification information is unique ID information of the peripheral terminal, and the friend information around the child holding the user terminal 20 can be known through the identification information.

When the user terminal 20 receives the identification information from the peripheral terminal, the received identification information is transmitted to the child safe server 30 through the mobile communication network (S114). At this time, the user terminal 20 transmits the location information of the user terminal 20 together with the identification information of the peripheral terminal to the child safe server 30.

The user terminal 20 checks whether a response signal is received from a peripheral terminal (S116). If a response signal is received from a peripheral terminal, the user terminal 20 performs the same process. If the response signal is not received for a predetermined time or longer, (S118).

When the network is released, the user terminal 20 transmits the identification information of the released network peripheral terminal to the child safe server 30. At this time, the user terminal 20 transmits the network disconnection fact and the location information of the user terminal 20 to the child safe server 30 together with the identification information of the peripheral terminal.

FIG. 5 illustrates a signal flow between respective components for performing a location-based secure service providing method according to the present invention.

Referring to FIG. 5, when an access point (AP) 10 broadcasts an excitation signal (S10), the user terminal 20 receives an excitation signal and generates a first signal in response to the excitation signal, 10 (S12).

If the user terminal 20 moves to an area where the excitation signal of the access point 10 is not in the state where the first communication is connected between the access point 10 and the user terminal 20, ≪ / RTI >

If the user terminal 20 does not receive the excitation signal for a certain period of time after receiving the last excitation signal, it broadcasts the second signal to the neighboring terminal (S14).

If there is another terminal in the vicinity of the user terminal 20, the peripheral terminal 20-1 transmits a response signal to the user terminal 20 in response to the second signal (S16).

In this manner, a network is formed through signal transmission / reception between the user terminal 20 and the peripheral terminal 20-1 (S18).

Although FIG. 5 illustrates formation of a one-to-one network between the user terminal 20 and the peripheral terminal 20-1, when the number of peripheral terminals is two or more, the user terminal 20 forms a network with each peripheral terminal, A mesh network may be formed between the user terminal 20 and peripheral terminals by forming a network in the same manner between neighboring terminals.

When a network is established between the user terminal 20 and the peripheral terminal 20-1, the user terminal 20 receives the identification information from the peripheral terminal 20-1 via the network (S20) To the security server 30 (S22). The user terminal 20 also transmits its own location information when transmitting the identification information of the peripheral terminal.

The child safe server 30 transmits the location information of the user terminal 20 and the identification information of the surrounding terminal to the child's parent terminal 40 through the mobile communication network.

According to the location based child rest assured service of the present invention, the position information of the child can be grasped through the first communication between the access point and the user terminal in the campus, and the network can be established through the second communication between the user terminals outside the school Not only the location information of the child but also the friend information of the child can be grasped.
