METHOD FOR DETECTING CAMP-ON AND CAMP-OFF OF MOBILE TERMINAL FOR ZONE BASED SERVICE IN MOBILE COMMUNICATION SYSTEM

摘要

Disclosed is a method for detecting cell camp-on and camp-off of a mobile terminal, in which a base station provides an effective zone based service by directly and simply detecting small cell camp-on and camp off of the mobile terminal without a help from a core network, that is, without a separate NAS message under a small cell environment of a mobile communication system by enhancing a tracking area update request processing scheme of the mobile terminal.
