What is WiMAX? WiMAX (Worldwide Interoperability for Microwave access)
WiMAX is based on the IEEE 802.16 specification for
Broadband Wireless Access The IEEE specifies only the PHY and MAC layer
WiMAX forum
promotes 802.16 technology
consist of silicon vendors, equipment manufactures andService Providers, 300+ members
is defining End-to-End IP architecture
Two versions of WiMAX
Fixed WiMAX based on 802.16-2004 802.16D
Mobile WiMAX based on 802.16-2005
802.16E

ACCESS SERVICE NETWORK (ASN)Broadband Wireless Gateway (BWG) provides the micro-mobility anchor point and
supports
bearer services. Also supports the Foreign Agent.
Base station (BS) provides the radio dependent functions and has limited IP functionality
CORE SERVICES NETWORK (CSN)
Home agent (HA) provides the macro-mobility anchor point and supports bearer services
, if roaming/mobility is desired.Other Network Elements such as AAA, DHCP servers and more are also in the CSN.

WiMAX Value Summary WiMAX value proposition is for operators to make money out of
delivering services on the new Internet model
WiMAX is free from the legacy wire line-cellular because its rootsare derived from the Internet
WiMAX will match speeds of LTE (current proposal of 20 MHz nowpart of 1.5 Release.)
WiMAX will have a cellular-based flavor of multicasting availablevia HSPA called Multimedia Broadcast Multicast Service or MBMS
WiMAX embraces QoS controls and tools which allow operators toembrace multi-tier service pricing and level marketing.
WiMAX is excellent where countries locations have no existinginfrastructure

ASN Profiles Three ASN Profiles have been specified in WiMAX as a tool to manage
diversity in ASN node usage and implementation
- Release 1 of NWG Specifications on WiMAX supports 3 ASN
Profiles:Profile A:
Centralized ASN Model with BS and ASN GW in separate platforms through R6interface
Split RRM: RRA in BS and RRC in ASN-GW
Open interfaces for Profile A: R1, R6, R4, and R3Profile B:
Distributed ASN solution with the BS and ASN GW functionalities implemented in asingle platform
Open interfaces Profile B: R4 and R3
Profile C: Similar to Profile A, except for RRM being non-split and located in BS. A bigdeparture from the way things used to be done in the mobile radio world.

802.16 Service Flow Model Packets are associated with a service flow, which is the central concept of
the MAC protocol
Service flow= an unidirectional flow of packets with a particular QoS
Service flow has parameters like bandwidth, latency, jitter and other QoS-related variables
When data comes to MAC layer, the convergence sublayer gives it anconnection ID (CID)
The service flow is mapped to this ID {CID,SFID}
The Service Flow ID is fixed across Base-Stations. Each Base-Stationmaps a SFID to a new CID.
Created on-demand or pre-provisioned
On-demand SF creation subject to authorization against permitted QoSparameters

802.16e Service Flows 802.16e supports multiple service flows for a given MS
The service flows are identified by mapping a set of classification rules over the packetbearer.
Each service flow is a unidirectional service flow and can have a different QoS treatment.
QoS treatment for service flows should be done end-to-end on the radio and corenetwork.
There are two types of service flows, Initial and secondary service flows.
The ISF (Initial service flow) is created automatically after user attachment.
The ISF results in an IP address assigned to the SS.
The SSF (secondary service flow), if needed, is only created after the ISF.
ASN Gateway R1.0 supports one ISF and three secondary service flows.

NAP sharing
NAP Sharing is the process at which the ASN is usedby two CSNs.
CSN could be either from two vendors or from twodifferent providers wishing to offer separate orcompeting services.
ASN Gateway supports NAP sharing with the use ofVRFs.
VRF is using for L3 routing separation and for user
group separation.

QoS in WiMax
QoS Support refers to both airlink QoS as well asmapping on the network.
ASNGW sends the QoS parameters to the BS forcreating appropriate service flows.
Certain hosts can be given additional quality of service
parameters A new R6 bearer (service flow) may be created
corresponding to the hosts IP address. Multiple hostcan use this service flow
The mapping of the host to the new R6 service flow iscreated, and communicated to the BS/MS via the RR-Request.
