Method and apparatus for communication of terminal in mobile communication system

A method performed by a second network entity, the method comprising:

• receiving, from a first network entity, a first message for a monitoring event, the first message including information on a monitoring duration and information on a guard time;
• transmitting, to the first network entity, a second message as a response to the first message;
• and
• detecting at least one monitoring event based on the first message,
• wherein the guard time indicates time value for which at least one monitoring event report detected for at least one terminal in a group is aggregated before transmitting the aggregated at least one monitoring event report, and
• wherein the time value of the guard time is less than the monitoring duration.

A first network entity comprising:

• a transceiver;
• and
• a controller configured to:
• transmit, to a second network entity via the transceiver, a first message for a monitoring event, the first message including information on a monitoring duration and information on a guard time, and
• receive, from the second network entity via the transceiver, a second message as a response to the first message,
• wherein the guard time indicates time value for which at least one monitoring event report detected for at least one terminal in a group is aggregated before transmitting the aggregated at least one monitoring event report, and
• wherein the time value of the guard time is less than the monitoring duration.
