METHOD FOR DETECTING SECURITY ERROR IN MOBILE TELECOMMUNICATIONS SYSTEM AND DEVICE OF MOBILE TELECOMMUNICATIONS

摘要

According to one embodiment, a method of performing a re-establishment procedure in a mobile communication system includes: receiving at least one packet data convergence protocol (PDCP) control plane data unit; performing an integrity check on the at least one PDCP control plane data unit; identifying an integrity check failure with regard to the at least one PDCP control plane data unit; and performing a re-establishment procedure if the integrity check failure is identified to exist with regard to the at least one PDCP control plane data unit.

1. An apparatus in a mobile communication system, the apparatus comprising:
a receiver configured to receive at least one packet data convergence protocol (PDCP) control plane data unit; and a controller operatively connected to the receiver and configured to:
perform an integrity check on at least one packet data convergence protocol (PDCP) data unit, and to identify an integrity check failure with regard to the at least one PDCP data unit; andperform a re-establishment procedure if the integrity check failure is identified to exist with regard to the at least one PDCP data unit.
