When VPN security tunneling is established between the situation management server 330 and the service application 314, the situation management server 330 and the service application 314 can maintain one security session. At this time, the information used for the authentication of the AVN terminal 310 and the situation management server 330 can use a certificate scheme or a pre-shared secret key, and a TLS (Transport Layer Security) VPN or IPsec ) VPNs can be used to build VPN secure tunneling.

In addition, the service app 314 may send an emergency message from the situation management server 330 to the on-demand channel daemon 312. Thereafter, the service app 314 maintains a receive-waiting state and may receive a receipt confirmation of the incoming message from the on-demand channel daemon 312 as a response to the normal receipt of the urgent message.

In addition, the service application 314 may transmit the completion of the reception of the emergency message to the situation management server 330. When the service application 314 receives connection termination from the situation management server 330, the service application 314 can release the security turnaround that was established with the situation management server 330. [ Thus, the communication connection between the situation management server 330 and the channel manager 340 and the AVN terminal 310 can be terminated.

The channel manager 340 may transmit a communication channel establishment request including information necessary for establishing a communication channel with the AVN terminal 310 from the situation management server 330. [ After receiving the communication channel establishment request from the situation management server 330, the channel manager 340 may transmit connection request information including information for connection with the situation management server 330 to the AVN terminal 310.
