Procedure for mobility management in a system architecture supporting mobility between different access systems

摘要

A method for mobility management MM in a system architecture supporting the movilidadentre different access systems having entities MM separate level core network CN (SGSN Omme of the preceding generation, MME LTE) as an area used MM common (equivalent area RATA), said method comprising: - a step (1) in which, when a UE leaves the coverage (UMTS coverage) of a primerode said access systems where in a state Offline radio as seen from LaRed radio access RAN, but seen in Connected state from the MM entity CN-level (SGSN or existing MME) of said first access system, for coverage (LTE coverage) of unsegundo of said access systems where it is in Idle state as seen from CN-level entidadMM (LTE MME) of said second access system, the UE releases its radio connection deseñalización in said first system access, thus putting the UE in the Idle state segúnse seen from the MM entity of the first CN-level access system.
