Layer 3 mobility isbased on mobile IP and can be implemented without the need for a mobile IP client.• The WiMAX architecture defines two generic reference models for radio resource management:one with and the other without an external controller for managing the BSresources.• The network architecture supports paging and idle-mode operation of mobile stations.10.12 Bibliography[1] WiMAX Forum.
