Scope of 802.16 Standard


Message and Flow between M/C planes and NCMS M_SAP (Management Service Access Point)

• System configuration• Monitoring statistics• Notifications/Triggers• Multi-mode interface management

C_SAP (Control Service Access Point)• Handovers (e.g. notification of HO request)• Idle mode mobility management (e.g. entering idle mode)• Subscriber and session management (e.g. session setup)• Radio resource management• AAA service signaling (e.g. EAP payload)• Media independent handover function services

IEEE802.16gIEEE802.16g


Others GPCS (Generic Packet Convergence Sublayer) SAP

• Parameters to define flow and data• Primitives for data transfer and receive

MAC management messages

- to transfer MIH (Media Independent Handover)

- to inform current NSP

- to query, notify and set Information Element ?

WiMAX has different Characteristics with WLAN Synchronized system QoS Mobility Broadcast/Multicast

Standards Element management for mobile will finish soon Network management is still open To accommodate new features (MBS, MMR, MIH, , ) needs

some extension, especially in network management layer
