As shown in FIG. 1, when the mobile phone 11 receives a power-off command from a user through a keypad, the mobile phone 11 ) Removes the power after registering the power off position with the base station 12 before turning off the power. The base station 12 transmits the power of the mobile phone 11 to the mobile switching center (MSC: Mobile Switching Center) through the base station control device 13, the mobile switching station 14 is the mobile phone The power of (11) is turned off and stored in the memory 15 (HLR: Home Loaction Register).

When the call is received to the mobile number, the mobile switching center 14 detects this and does not attempt to connect to the mobile phone 11 through the base station 12, and the user's mobile phone is turned off and is transferred to the mailbox. The message will be delivered to the caller and the charge of using the mobile phone will begin.

In addition, if there is a pre-recorded greeting from the user in the memory 15, the mobile switching center 14 transmits the user's greeting to the caller, and receives a voice message or a telephone number from the caller and stores the greeting in the memory 15. .

The caller hears the announcement message instead of the dial tone for the connection, and the mobile switching center 14 does not attempt to connect to the incoming call to the cellular phone which is cut off, thereby saving the resources of the cellular phone network.

Therefore, conventionally, when a call is received by a mobile phone that is cut off, the mobile phone does not attempt to connect to the mobile phone and transmits a message indicating that the caller is switched to a mailbox. If the user's greeting is recorded in advance, the user's greeting is sent to the caller. It uses the method of registering the guide message when the mobile phone is cut off.

However, in the conventional technology as described above, the user has a complicated process of registering the reason for turning off the mobile phone while the mobile phone user turns off the mobile phone as a voice message instead of a greeting.

In addition, when the caller makes a call to the mobile phone number that is turned off, the mobile switching center transmits a notification message to the caller to be transferred to the mailbox, and charges a call from the time when the call is switched to the mailbox. If there is a message pre-recorded by the user or a message about the reason for the power off of the mobile phone, it is transmitted to the caller, so there is a problem in that the user must pay the call charge to hear the user's greeting or the power-off reason that may not be recorded.

Therefore, the present invention devised in view of the above problems, when the mobile phone is turned off or the mode is changed, the user can easily receive the power-off or mode change reason from the user through the keypad, the power-off or mode change in the memory of the mobile switching center. It is an object of the present invention to provide a method for notifying of a call disablement that can notify a user of a call disablement reason by storing a call disablement reason according to the present invention.
