Abstract
Methods and apparatus are disclosed for a wireless transmit/receive unit (WTRU) to perform a multi-radio access technology (RAT) access (MRA) operation. The apparatus may include a WTRU non-access stratum (NAS) entity to communicate with a first and second NAS entity of a first and second core network (CN). Alternatively, the first WTRU NAS entity communicates with a first NAS entity of a first CN, and a second WTRU NAS entity communicates with a second NAS entity of a second CN. The apparatus may include a radio resource control (RRC) entity which controls a first RAT connected to the first CN and a second RAT connected to the second CN. Alternatively, the apparatus includes an RRC entity which controls a first connection using a first RAT connected to the first CN and a second connection using a second RAT connected to a second CN.
