A METHOD FOR MOBILITY MANAGEMENT IN A SYSTEM ARCHITECTURE SUPPORTING MOBILITY BETWEEN DIFFERENT ACCESS SYSTEMS

摘要

It is an object of the present invention to provide an MM method in a system architecture that supports mobility between different access systems with separate core network (CN) level MM entities using a common mobility management (MM) ) Leaves the coverage of the first access system of the access systems that are in the non-wireless connection state when viewed from the radio access network (RAN) but are seen in the connection state when viewed from the CN level MM entity, the CN level MM In the case of coverage of a second access system of the access systems in an idle state as viewed from an entity, causing the UE to be in an idle state when viewed from a CN level MM entity of the first access system And to provide a mobility management method.
