Method and apparatus for handling Mobility between 3GPP Networks - not to 3GPP

摘要

Disclosed are a method and an apparatus for the handling of mobility between a Radio Access Technology (RAT) that does not belong to the Joint Project (3GPP) and a Third Generation Rat 3GPP includes the use of services provided through the rat that does not belong to the 3GPP.There is a need to use services provided by 3GPP and the rat enters a State of Layer without Access 3GPP (NAS). 3GPP is tunneled messages to the Network on the rat EPC 3GPP access that does not belong to the 3GPP and makes a Transition from the rat that does not belong to the 3GPP towards Rat 3GPP.Performs a State Transition from the nas 3GPP and there is a transition to a Second State in 3GPP.
