WiMAX Registration procedure used by Subscriber station(SS)
This page describes fixed wimax registration procedure as per IEEE 802.16 OFDM MAC layer specifications. It covers registration messages such as REG REQ and REG RSP as per wimax standard.
The purpose here is to allow SS entry into wimax network and make it manageable.
The registration procedure is outlined below.
• SS transmits REG-REQ message to BS.
• BS responds with REG RSP message including secondary management CID if the SS is managed SS.
• Managed SS will establish secondary management connection and configure its IP connectivity.
• A unmanaged SS will setup provisioned connections.
WiMAX compliant SS and BS will negotiate IP version during REG REQ and REG RSP message exchange if the SS is managed. After the registration is done, SS shall invoke DHCP mechanisms to obtain IP connectivity.
WiMAX REG REQ
Following are the typical fields carried in wimax REG REQ message.
|REG REQ field|
|REG REQ Type|
|SS management support(TLV)|
|IP management mode(TLV)|
|Number of uplink CID supported(TLV)|
|Classification/PHS options and SDU encapsulation support(TLV)|
|Maximum number of classifiers(TLV)|
|ARQ Support(TLV )|
|DSx flow control(TLV)|
|Multicast polling group CID support(TLV)|
|PKM flow control(TLV)|
|Vendor ID encoding(TLV)|
WiMAX REG RSP
Following are the typical fields carried in wimax REG RSP message.
|REG RSP field|
|REG RSP type|
|SS management support(T)|
|IP managed node|
|number of uplink cid support(T)|
|classification/PHS options and SDU encapsulation(T)|
|max. num of classifiers(T)|
|DSx flow control(T)|
|MCA flow control(T)|
|Multicast polling group cid support(T)|
|PKM flow control(T)|
|Vendor ID encoding(T)|
