Embodiments for enabling traffic content identification by a wireless transmit/receive unit are provided. The WTRU may store interface binding entries in a database associating links in a web page to various traffic content types, such as video, audio, and text. Upon a request to access one of the links, a socket may be created based on a data mobility policy associated with the traffic content type. Alternately, the database may associate the links directly to interface types based on the data mobility policies. The Access Network Discovery and Selection Function (ANDSF) may provide the data mobility policies to the WTRU.
