1.2.5.7 Reference Points
 Reference point R1 consists of the protocols and procedures between the MS
and ASN as per the air-interface (PHY and MAC) specifications (IEEE 802.16e).
 Reference point R2 consists of protocols and procedures between the MS and
CSN associated with authentication, services authorization and IP host
configuration management. This reference point is logical in that it does not
reflect a direct protocol interface between the MS and CSN. The authentication
part of reference point R2 runs between the MS and CSN operated by the
home NSP, however, the ASN and CSN operated by the visited NSP may
partially process the aforementioned procedures and mechanisms. Reference
point R2 might support IP host configuration management running between
the MS and CSN (operated by either the home NSP or visited NSP).
 Reference point R3 consists of the set of control plane protocols between the
ASN and CSN to support AAA, policy enforcement and mobility management
