Hereinafter, a method and an apparatus for managing a connection of a security system according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram showing a security system according to an embodiment of the present invention.

As shown in FIG. 2, the security system may allow at least one secure base station 100 and the management terminal 200 to be connected through a network.

In this case, the network corresponds to an Ethernet network, and the security system may allow the security base station 100 and the management terminal 200 to be connected by using TCP / IP to transmit and receive security data.

Here, the security base station 100 refers to a small base station capable of controlling a mobile phone by transmitting a function restriction signal or a function restriction release signal within a predetermined area.

That is, the security base station 100 may control the mobile phone by transmitting a function restriction signal when installed in the entrance area entering the security area, and by transmitting a function restriction release signal when installed in the entrance area.

The management terminal 200 is a device for managing the security base station 100, includes a security base station 100 management program, and manages identification information or IP address information assigned to each security base station 100.

On the other hand, in the security system having such a configuration, the management terminal 200 acts as a TCP / IP interface server and the security base station 100 acts as a TCP / IP interface client, thereby securing the security with the management terminal 200. The base station 100 may be connected to 1: N.

Accordingly, the security system allows the secure base station 100, which is a client, to generate a keepalive message and transmit the generated keepalive message to the management terminal 200, so that the at least one secure base station is received through the keepalive message received by the management terminal 200, which is a server. Manage (100).

In addition, the security system allows the management terminal 200 as a server to generate a connection message for informing that the virtual line using TCP / IP is active and to transmit it to the security base station 100 at predetermined intervals. For this reason, the management terminal 200 may include a timer for counting a predetermined period.

The security base station 100 also includes a timer, by transmitting a keep-alive message generated according to a predetermined period to the management terminal 200, by counting the reception time of the connection message received from the management terminal 200, the management terminal It may be determined that the connection state with the 200 is in a normal state.

In addition, when the connection message is not received from the management terminal 200 for a preset time, the secure base station 100 determines that the connection state with the management terminal 200 is an abnormal state, and establishes TCP / TCP with the management terminal 200. Disconnect the IP connection.

That is, after receiving the connection message from the management terminal 200 lastly, the secure base station 100 determines that a problem occurs in the management terminal 200 or the virtual line if the connection message is not received for a predetermined time. Then, the connection with the management terminal 200 is released.

The secure base station 100 may disconnect from the management terminal 200 and then reconnect with the management terminal 200 by transmitting a reconnection request message to the management terminal 200.

Next, the connection management method of the security system having such a configuration will be described in detail.

3 is a signal flow diagram illustrating a connection management method of a security system according to an embodiment of the present invention.

As shown in FIG. 3, in the security system including the security base station 100 and the management terminal 200, when the initial booting is performed, the security base station 100 and the management terminal 200 use preset port information. Each of them creates a socket and performs a connection using TCP / IP (S101).

Here, the management terminal 200 is a server, the security base station 100 is connected in a 1: N manner to be a client, the management terminal 200 is the identification information assigned to each security base station 100 connected to TCP / IP or Each security base station 100 is managed through IP address information.

The secure base station 100 and the management terminal 200 connected as described above drive timers included in each of them (S102 and S103).

The management terminal 200 counts a predetermined time through the driven timer, generates a connection message according to a preset period, and transmits the connection message to the secure base station 100 (S104). That is, the management terminal 200 transmits a connection message to the secure base station 100 to inform that the virtual line using TCP / IP with the secure base station 100 is active according to a preset period.

As such, the secure base station 100 receiving the connection message according to a preset period from the management terminal 200 counts a predetermined time through a driven timer and generates a keep-alive message according to the preset period. It can transmit to 200 (S105).

The keep-alive message refers to a message transmitted by the secure base station 100, which is a client, to inform the management terminal 200 that the virtual line using TCP / IP between the two is still active.

Therefore, the management terminal 200 can determine the connection state of the connected security base station 100 by receiving a keepalive message from the security base station 100 according to a preset period.

On the other hand, the secure base station 100 and the management terminal 200 connected via TCP / IP and transmitting and receiving connection messages and keepalive messages as described above are abnormally interrupted in data communication or virtually due to external or internal problems. If the line is disconnected.

Accordingly, the management terminal 200 does not receive the keepalive message transmitted by the secure base station 100 (S106).

Therefore, the management terminal 200 determines that a problem has occurred in the secure base station 100 or the virtual line if the keep-alive message is not received for a predetermined time since the last keep-alive message is received from the secure base station 100. And releases the TCP / IP connection with the secure base station 100 (S107).

Meanwhile, the secure base station 100 may have a case in which a connection message is not received from the management terminal 200 due to problems of TCP / IP release and a virtual line of the management terminal 200 (S108).

In such a case, if the connection message is not received such that the predetermined time elapses since the last reception of the connection message from the management base station 100, a problem occurs in the management terminal 200 or the virtual line. It is determined that the connection to the management terminal 200 via TCP / IP (S109).

In addition, the secure base station 100 generates and transmits a reconnection request message to the management terminal 200 (S110).

Meanwhile, when the TCP / IP connection with the secure base station 100 is released, the management terminal 200 receives a reconnection request message from the secure base station 100, and transmits a reconnection response message corresponding thereto. (S111).

When the management terminal 200 transmits a reconnection response message, the management terminal 200 performs reconnection with the secure base station 100 using TCP / IP (S112).

Here, the security base station 100 does not receive a reconnection response message corresponding to the reconnection request message transmitted within a preset time, and may repeat the retransmission of the reconnection request message to the management terminal 200.

As such, even if a problem occurs in the TCP / IP connection between the security base station 100 and the management terminal 200, the security system may detect and recover it quickly through a connection message and a keep-alive message.

4 is a flowchart illustrating a connection management method of a security system according to an embodiment of the present invention.

As shown in FIG. 4, the security system allows each secure base station 100 and the management terminal 200 to generate sockets using preset port information, respectively, when initial booting is performed (S201).

In addition, the security system allows the management terminal 200 to manage each security base station 100 by registering identification information or IP address information of each security base station 100 connected through a network (S202).

After the security base station 100 creates a socket, the security system transmits a connection request message to the management terminal 200, and the management terminal 200 receiving the connection transmits a connection response message corresponding thereto to the security base station 100. By transmitting to each other, the connection using TCP / IP is performed (S203).

In this case, in the security system, the management terminal 200 is a server, and each security base station 100 is connected in a 1: N manner of being a client.

When the TCP / IP connection is performed between the security systems, the management terminal 200 generates a connection message according to a preset period and transmits the connection message to the secure base station 100 (S204).

Therefore, the security system allows the security base station 100 to determine the connection state with the management terminal 200 at a predetermined time period.

Meanwhile, the security system generates a keepalive message and transmits the keep-alive message to the management terminal 200 according to a preset time, so that the management terminal 200 manages the connection state of each security base station 100. (S205).

On the other hand, if the security system is not received by the management terminal 200 for more than a predetermined time due to the failure of the security base station 100 and the problem of the virtual line between each other, the keepalive message transmitted from any security base station 100 ( S206), the management terminal 200 to release the TCP / IP connection with the secure base station 100 (S207).

In addition, when the security system does not receive a connection message from the management terminal 200 for a predetermined time or more at the base station 100 shown (S208), the secure base station 100 also connects to the TCP / IP with the management terminal 200. To release (S209).

In addition, the security system allows the security base station 100 to transmit a reconnection request message, which is a message for requesting TCP / IP reconnection, to the management terminal 200 (S210).

The security system, the management terminal 200 generates a reconnection response message corresponding to the reconnection request message received from the security base station 100 and transmits to the security base station 100 (S211), the secure base station 100 and A reconnection using TCP / IP is performed (S212).

Here, the security base station 100 does not receive a reconnection response message corresponding to the reconnection request message transmitted within a preset time, and may repeat the retransmission of the reconnection request message to the management terminal 200.

 As described above, even if a problem occurs in the TCP / IP connection between the security base station 100 and the management terminal 200, the security system determines the connection through the connection message and the keep-alive message and reconnects to prevent abnormal disconnection. Can be.

Meanwhile, the above-described present invention has been described only in the case where the security base station 100 transmits a control signal for controlling the camera function of the mobile phone, but in the case of controlling the network connection function, storage function, etc. of the mobile phone, the same is the same. Can be applied.

As described above, the method and apparatus for managing a connection of a security system according to the present invention allow the management terminal to operate as a server and the security base station as a client so that the management terminal can efficiently establish a TCP / IP connection state with a plurality of security base stations. By managing it, even if a failure occurs in the connection state between each other, it can be detected and recovered quickly.
