Abstract

The primitives between an upper management layer and the MAC layer within a mobile station and a base station are defined in order to specify and clarify the operations within the protocol stack layers in a broadband wireless access system to allow a mobile station to perform scanning procedures. Media Independent Handover (MIH) procedures can be achieved because the NCMS and MIH
layer can communicate through use of these primitives.
