At this time, the mobile terminal 100 performs a session connection with the call processing device 200 based on Session Initiation Protocol (SIP).

Thereafter, the mobile terminal 100 maintains a standby state (Always On) according to the session connection with the call processing device 200 until the power is turned off (Power Off) (S106).

At this time, when the mobile terminal 100 receives the IMS service request from the user, the mobile terminal 100 accesses the service server 500 corresponding to the IMS service based on the session connection, and accordingly receives the IMS service information from the service server 500. To the user.

The call processing apparatus 200 performs a session connection with the mobile terminal 100 and generates a connection notification message for notifying the subscriber management apparatus 300 that the session connection with the mobile terminal 100 has been performed. Then, the call processing device 200 transmits the generated access notification message to the subscriber management device 300 (S108).

The subscriber management apparatus 300 receives the access notification message of the mobile terminal 100 from the call processing apparatus 200, and the mobile terminal 100 sets a preset period (eg, 1) based on the received access notification message. It is determined whether or not the IMS service is used within a year) (S110).

In this case, the subscriber management apparatus 300 determines whether the mobile terminal 100 uses the IMS service based on previously stored IMS service usage information.

As a result of the determination in step S110, when the IMS service is used within a predetermined period, the subscriber management apparatus 300 maintains the operation state of the mobile terminal 100. That is, the subscriber management apparatus maintains the state of the mobile terminal without any action (S112).

As a result of the determination in step S110, when the IMS service is not used within the preset period, the subscriber management apparatus 300 generates a control message for controlling the session connection application in the mobile terminal 100 not to operate (S114). In step S116, the generated control message is transmitted to the mobile terminal 100 through the call processing apparatus 200.

The mobile terminal 100 receives the control message from the subscriber management apparatus 300, and terminates the session connection application based on the received control message (S118). Then, the session connection application operation is set to terminate (S120).

Subsequently, the mobile terminal 100 does not operate the session connection application at the time of power-on after power off (S122). Accordingly, the mobile terminal 100 is configured for the call processing device and the IMS service. Do not establish a session connection.
