NON -ACCESS STRATUM PROTOCOL MANAGEMENT METHOD AND SYSTEM IN MOBILE TELECOMMUNICATION SYSTEM

摘要

PURPOSE: A method for treating non-access stratum(NAS) of mobile communication system is provided to safely and efficiently perform security, mobility, and session management. CONSTITUTION: An UE(user equipments)(110) is placed inside a cell which is service area of eNB(evolved Node Base station)(112). A MME(Mobility Management Entity)(114) is able to manage mobility of UE using UE and NAS protocol message through eNB. The NAS protocol message comprises protocol classifier, classifier extension. The protocol classifier classifies ESM(Evolved Session Management) message, EMM(EPS Mobility Management) message, or protocol classifier extension.
