DATA FLOW MOBILITY
First Claim
Patent Images
1. A wireless transmit/receive unit (WTRU), the WTRU comprising:
- a processor configured to make a determination based on mobility policy information to transfer a data flow from a first access network of a first radio access technology (RAT) to a second access network of a second RAT; and
a transmitter configured to transmit a message, the message requesting transfer of the data flow from the first access network to the second access network and including flow identification information associated with the data flow.

Abstract
A wireless transmit/receive unit (WTRU) may communicate using a data flow that is defined according to flow identification information (FII). The WTRU may participate in the transfer of the data flow between access networks of diverse radio access technologies. The WTRU may communicate with a mobility function to obtain access network and mobility policy information. The mobility function may be, for example, an Access Network Discovery Function (ANDSF). The mobility policy information may describe the conditions by which the transfer of data flows between access networks may be permitted.
