1, the connection class setting system includes a terminal 110 and a connection class setting apparatus 120. [

The terminal 110 is a terminal connected to a mobile communication network and provided with a communication service. At this time, the terminal 110 is equipped with a universal subscriber identity module, and the wireless terminal can store a connection class. At this time, the terminal 110 receives access control barring information from the mobile communication network. At this time, the connection control information may be information indicating a time when the connection restriction of the terminal 110 is applied. The terminal 110 blocks access to the mobile communication network for a period of time included in the connection control information when the connection class of the terminal 110 stored in the wake state according to the connection control information is of a connection restricted class. In addition, when the terminal 110 receives the connection class setting message from the connection class setting device 120, the terminal 110 can change the connection class of the terminal 110. 3 and 4, the process of establishing a connection class by the terminal 110 will be described in detail.

The connection class setting apparatus 120 is connected to the mobile communication network and transmits a connection class setting message to the terminal 110 through the mobile communication network, which requests the terminal 110 to change the connection class. At this time, the connection class setting apparatus 120 may include a database for storing connection classes of the terminal 110 for each disaster situation. At this time, the disaster situation can be defined as a predetermined item according to the kind of the disaster, the degree of the disaster, and the place where the disaster occurs. For example, a disaster situation can be defined as a pre-specified disaster situation called "an earthquake of magnitude 3.0 or higher in the metropolitan area". The connection class setting apparatus 120 may receive an input from the manager to select one of the defined items of each disaster situation. The connection class setting apparatus 120 transmits a connection class setting message including the connection class of the terminal 110 corresponding to the disaster situation selected by the administrator to the terminal 110 via the mobile communication network. At this time, the connection class setting apparatus 120 can transmit a connection class setting message to the terminal 110 by using the SMS WAP (Wireless Application Protocol) Push method. Alternatively, when the terminal 110 is powered on or receives a signal for requesting a class setting message from the terminal 110, the connection class setting device 120 transmits a connection class setting message to the terminal 110 in a Pull manner .

At this time, the mobile communication network may be a communication network including a known type MME (Mobility Management Entity) 130.

The MME 130 previously stores connection control information including a time at which a connection restriction corresponding to each connection class is applied, and periodically transmits connection control information to the terminal 110 in the form of a SIB (System Information Block) 2 message send.

2 is a flowchart illustrating a connection class setting system according to an embodiment of the present invention.

Referring to FIG. 2, in step 210, the connection class establishing apparatus 120 receives an input from the manager to select any one of the disaster situations.

In step 220, the connection class setting apparatus 120 transmits a connection class setting message including the connection class of the terminal 110 corresponding to the selected disaster state to the terminal 110 in step 210. At this time, the connection class establishing apparatus 120 may previously store an access class corresponding to each disaster situation for each of the one or more terminals 110. Alternatively, the connection class setting apparatus 120 may classify each of the terminals 110 into one or more groups, and may previously store an access class corresponding to each disaster situation for each group. For example, the connection class setting device 120 generates groups each including a terminal 110 of a user belonging to each institute that copes with a disaster situation such as a police or a paramedic, for each organization, The connection class can be stored in advance.

In step 230, the terminal 110 changes the connection class of the terminal 110 according to the connection class setting message. In this case, the terminal 110 may include an interface for directly changing the connection class stored in the worm, and may change the connection class stored in the worm through the interface. Alternatively, the terminal 110 may receive the connection class setting information and store the connection class setting information in the memory, and then connect or disconnect the connection class according to the connection class setting information stored in the memory, rather than the connection class stored in the wake up state.

In step 240, the terminal 110 transmits the connection class to the MME 130 of the mobile communication network. At this time, the terminal 110 can transmit the connection class from the terminal 110 to the MME 130 in the process of attaching to the mobile communication network.

In step 250, the MME 130 transmits connection control information corresponding to the connection class received in step 240 to the terminal 110.

In step 260, the terminal 110 receives an input from the user to request a connection. In this case, the input for requesting connection refers to all inputs for requesting connection of the terminal 110 to a mobile communication network such as a call request, data transmission, and the like.

In step 260, the terminal 110 determines whether the condition according to the access control information is satisfied. For example, the terminal 110 determines whether the current time corresponds to a time at which the access restriction included in the access control information is applied.

If the condition according to the connection control information is satisfied in step 260, the terminal 110 blocks access to the mobile communication network (access control barring) in step 270.

If the condition according to the connection control information is not satisfied in step 260, the terminal 110 performs connection to the mobile communication network in step 280.

In step 420, the terminal 110 changes the connection class of the terminal 110 according to the connection class setting message. At this time, the terminal 110 changes the connection class stored in the idle state or changes the path of the connection class for confirming the connection class in the process of accessing the mobile communication network to the connection class setting message stored in the memory It can be changed to the path of the connection class.

In step 430, the terminal 110 transmits the connection class to the MME 130. At this time, the terminal 110 detaches according to the connection class setting message, and transmits the connection class from the terminal 110 to the MME 130 in the attach process.

In step 440, the terminal 110 receives connection control information corresponding to the terminal 110 from the MME 130.

In step 450, the terminal 110 receives an input through the input unit 360 to request a connection from the user to the mobile communication network. For example, the terminal 110 may receive an input from a user requesting to perform a telephone call.

In step 460, the UE 110 determines whether the condition according to the access control information is satisfied. For example, the terminal 110 determines whether the current time corresponds to a time at which the access restriction included in the access control information is applied.

If the condition according to the access control information is satisfied in step 460, the terminal 110 blocks access to the mobile communication network in step 470 (access control barring).

If the condition according to the connection control information is not satisfied in step 460, the terminal 110 performs connection to the mobile communication network in step 480. [
