Abstract
A method and apparatus for multiple radio access technology (multi-RAT) access mode operation for a wireless transmit/receive unit (WTRU) are disclosed. A WTRU and a network may enable a multi-RAT access mode of operation based on at least one of WTRU subscription, a service agreement of the WTRU, a roaming status of the WTRU, a selected access point name (APN), an Internet protocol (IP) flow class, a subscriber profile identity for the WTRU, requested quality of service, or a proximity indication indicating proximity to a cell supporting multi-RAT access mode. The WTRU may send a capability indication of support of multi-RAT access to a network, wherein the multi-RAT access mode is enabled based on the capability indication. A partial handover of bearers may be performed. In performing the handover, the target cell is determined based on a priority rule.

Claim
A method for multiple radio access technology (multi-RAT) access mode operation implemented in a wireless transmit/receive unit (WTRU) the method comprising:
registering using a first radio access technology (RAT), wherein an indication for multi-RAT access is received from a network during the registration using the first RAT;
establishing a bearer in a second RAT based on the indication of multi-RAT access; and
initiating a transfer of a data flow from the first RAT to the second RAT.
2. The method of claim 1, wherein establishing a bearer in the second RAT is further based on a state of the WTRU.
3. The method of claim 1, wherein the indication is received from a node in a radio access network, RAN.
4. The method of claim 1, wherein the establishing a bearer in the second RAT is further based on at least one of a radio condition and a load condition.
5. The method of claim 1, wherein the first RAT and the second RAT are in a first network.
6. The method of claim 1, wherein establishing the bearer in the second RAT is triggered by a network attachment procedure or a session management procedure.
7. A wireless transmit/receive unit (WTRU) for multiple radio access technology (multi-RAT) access mode operation, comprising:
a processor operatively coupled to a transceiver, the processor and transceiver configured to register using a first radio access technology (RAT), wherein an indication for multi-RAT access is received from a network during the registration using the first RAT;
the processor and transceiver further configured to establish a bearer in a second RAT based on the indication of multi-RAT access; and
the processor and transceiver further configured to initiate at least a partial handover from the first RAT to the second RAT.
8. The WTRU of claim 7, wherein the indication is received from a node in a radio access network, RAN.
9. The WTRU of claim 7, wherein the establishing a bearer in the second RAT is further based on at least one of a radio condition and a load condition.
10. The WTRU of claim 7, wherein the first RAT and the second RAT are both in a first network.
11. The WTRU claim 7, wherein establishing a bearer in the second RAT is further based on a state of the WTRU.
12. The WTRU of claim 7, wherein establishing the bearer in the second RAT is triggered by a network attachment procedure or a session management procedure.
