Method and apparatus for using non-access stratum procedures in a mobile station to access resources of component carriers belonging to different radio access technologies
First Claim
1. A wireless transmit/receive unit (WTRU) configured to perform a multi-radio access technology (RAT) access (MRA) operation, the WTRU comprising:
- a WTRU non-access stratum (NAS) entity configured to communicate with a first NAS entity of a first core network and a second NAS entity of a second core network, wherein a first RAT is connected to the first core network and a second RAT is connected to the second core network;
a radio resource control (RRC) entity configured to control a first connection using the first RAT and a second connection using the second RAT; and
a transceiver configured to send a registration message to the first core network using the first RAT, wherein the registration message includes a request for registration with the first core network of the first RAT and a request for registration with the second core network of the second RAT.

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.

9. A method, performed by a wireless transmit/receive unit (WTRU), for multi-radio access technology (RAT) access (MRA) operation, the method comprising:
-
communicating, by a WTRU non-access stratum (NAS) entity, with a first NAS of a first core network and a second NAS entity of a second core network, wherein a first RAT is connected to the first core network and a second RAT is connected to the second core network; controlling, by a radio resource control (RRC) entity, a first connection using the first RAT and a second connection using the second RAT; and sending a registration message to the first core network using the first RAT, wherein the registration message includes a request for registration with the first core network of the first RAT and a request for registration with the second core network of the second RAT. - View Dependent Claims (10, 11)
