WIRELESS COMMUNICATION SYSTEM AND METHOD OF IMPLEMENTING EVOLVED SYSTEM ATTACHMENT PROCEDURE

摘要

PROBLEM TO BE SOLVED: To provide a wireless communication system and method of implementing an evolved system attachment procedure.SOLUTION: A system comprises: a first core network; and a second core network which is evolved from the first core network. A wireless transmit/receive unit (WTRU) sends an attach request message to the second core network. The second core network activates packet data protocol (PDP) context and sends an attach accept message to the WTRU. The attach accept message comprises information regarding the PDP context. The second core network constructs session and mobility management (SMM) context for session management (SM) and mobility management (MM) for the WTRU.
