1.3 Mobile WiMAX Network Configuration

Mobile WiMAX network is composed of ASN and CSN. ACR and RAS are involved in
ASN and WSM is the Network Element(NE) to manage ACR and RAS. CSN is composed
of AAA server, HA and PCRF server. ASN is connected with CSN by router and switch.
The following diagram shows the composition of Mobile WiMAX network.
WSM
RAS
Radio Access Station (RAS)
RAS as the system between ACR and MS has the interface with ACR and provides the
wireless connection to MS under IEEE 802.16d/16e standards to support wireless
communication service for subscribers.
RAS carries out wireless signal exchange with MS, modulation/demodulation signal
processing for packet traffic signal, efficient use of wireless resources, packet scheduling
for Quality of Service(QoS) assurance, assignment of wireless bandwidth, Automatic
Repeat Request(ARQ) processing and ranging function. In addition, RAS controls the
