Abstract
Official abstract text for this publication.
An operation method of a terminal in a communication system may comprise: receiving a first occurrence reporting condition of a handover problem from a source base station; performing a handover from the source base station to a target base station; identifying whether a handover problem occurs based on the first occurrence reporting condition while performing the handover; and in response to identifying that a handover problem occurs, transmitting information indicating the occurrence of the handover problem to the target base station.
First claim
Opening claim text (preview).
What is claimed is: 1 . An operation method of a terminal in a communication system, the operation method comprising: receiving a problematic handover-related reporting condition from a source cell; performing a handover from the source cell to a target cell; in response to the handover being successful and the problematic handover-related reporting condition being satisfied, storing first information related to the handover; and transmitting, to the target cell, second information indicating the first information related to the handover is stored. 2 . The operation method according to claim 1 , wherein the first information related to the handover includes information on a handover problem affecting performance of the successful handover. 3 . The operation method according to claim 2 , wherein the first information related to the handover includes information related to an outage time during the handover. 4 . The operation method according to claim 2 , wherein the first information related to the handover includes information related to an interruption time of the handover. 5 . The operation method according to claim 1 , wherein the problematic handover-related reporting condition is received from the source cell through a radio resource control (RRC) reconfiguration message. 6 . The operation method according to claim 1 , wherein the second information corresponds to a handover problem indicator included in an RRC reconfiguration complete message transmitted to the target cell, and the handover problem indicator is set to a value indicating that first information related to the handover is available. 7 . The operation method according to claim 1 , further comprising: receiving a transmission request for a content report of the first information related to the handover from the target cell; and transmitting the content report to the target cell.
