Patent ID: 8054799

Claim:
A method for routing frames in one or more radio access networks based on a physical addressing scheme, the method comprising: an access point serving a mobile station assigning a unique identifier to a first virtual local area network, wherein the unique identifier is a virtual local area network identifier and wherein the first virtual local area network includes a path connecting the access point to a first radio network serving node, wherein the first virtual local area network, for each of a plurality of nodes in the first radio access network, is associated with at least one of a port for routing frames towards the first radio network serving node or a port for routing frames towards the access point; at least one of the access point and the first radio network serving node unicasting frames that include a destination address associated with the mobile station from the first radio network serving node towards the access point using the first virtual local area network; the access point determining that the mobile station is moving from a location adjacent the access point toward a target access point; and the first radio network serving node bicasting a first copy of frames addressed to the mobile station and a second copy of said frames addressed to the mobile station, wherein the first copy of said frames includes the virtual local area network identifier associated with the access point and the second copy of said frames includes a virtual local area network identifier associated with the target access point.
