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 for a wireless transmit/receive unit (WTRU), the method comprising:
measuring, by the WTRU, a condition based on a policy, wherein the WTRU has a bearer with a first radio access technology based on an identification (ID); and establishing a bearer in a second RAT using the ID based on the measured condition and one or more related thresholds.
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 policy is received from a node in a radio access network (RAN).
4. The method of claim 1, wherein the policy is 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. 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 measure a condition based on a policy, wherein the WTRU has a bearer with a first radio access technology based on an identification (ID); and the processor operatively coupled to the transceiver further configured to establish a bearer in a second RAT using the ID based on the measured condition and one or more related thresholds.
7. The WTRU claim 6, wherein establishing a bearer in the second RAT is further based on a state of the WTRU.
8. The WTRU of claim 6, wherein the policy is received from a node in a radio access network (RAN).
9. The WTRU of claim 6, wherein the policy is at least one of a radio condition and a load condition.
10. The WTRU of claim 6, wherein the first RAT and the second RAT are both in a first network.
