ABSTRACT:
A method (400, 500, 800), and apparatus (212, 230, 240) provide for mobility in WLAN voice systems. In one embodiment a processor (651) coupled to a memory (652) and a radio resource (653) determines from that client (150) should move, based for example on a signal parameter, to an adjacent MSN (240). Adjacent MSNs are discovered and a modification of a portion of a tunnel switched path to the adjacent MSN is made and a portion released after the modified path is established. Information is transferred to client150over the tunnel using a lower layer address such as a MAC address.
