Wireless metropolitan area network architecture for managing network resources and mobility

摘要

The present invention proposes an infrastructure to enable seamless mobility for wireless metropolitan area networks (WMANs) and to provide for management of spectrum and network resources. An WMAN reference model is introduced where the radio resource management (RRM) and handover (HO) sub-layer is introduced into the protocol stack. The WMAN management plane is responsible for the RRM and HO management. Several physical and logical network architecture options for WMAN management are proposed.

主权项

1. A wireless transmit/receive unit (WTRU), comprising:
a mobile Internet protocol (IP) part; a handover sublayer, the handover sublayer being specific to a type of a wireless network in which the WTRU operates and configured to receive a handover instruction from within the network; a media independent handover (MIH) lower layer convergence function (LLCF), the LLCF being specific to a type of the wireless network; a MIH handover function; and a MIH higher layer convergence function.
