摘要：
When a radio terminal (2) in a first RAT RRC_INACTIVE state in the first radio access network (RAN) (3) and having a Non-Access Stratum (NAS) connection with a first core network (CN) (4) associated with the first RAT moves to a cell (51) of a second RAN (6), the radio terminal (2) alters an RRC state transition operation of the radio terminal (2) depending on whether the second RAN (6) supports interworking with at least one of the first CN (4) and the first RAN (3).
