Category Description
(1)~(2) The MS sends the RAS the RNG-REQ message containing the MAC address and
Ranging Purpose Indication of the MS. The RAS assigns the Basic & Primary
Management CID and sends the RNG-RSP message to the MS.
(3)~(4) The MS sends the RAS the SBC-REQ message containing the physical parameter
and authorization policy information the MS supports. To request the authorization
policy, the RAS sends the ACR the MS_PreAttachment_Req message containing the
authorization policy support value using the default IP address and UDP port number
of the ACR.
(5)~(7) The ACR sends the RAS the MS_PreAttachment_Rsp message containing the
supported authorization policy. The RAS extracts the information received from the
ACR and sends the MS the SBC-RSP message containing it. Then the RAS sends
the ACR the MS_PreAttachment_Ack message to explicitly provide notification of the
start time of the next procedure (EAP transmission).
(8) The subscriber authentication procedure is performed between the MS and AAA
server. When the authentication is successful, the ACR receives provisioned policy
information for each subscriber from the AAA server.
For more information, see 4.1.2 Authentication.
(9)~(13) The MS sends the RAS the REG-REQ message containing the registration
information (MS Capabilities, CS Capabilities, HO Support, etc.). The RAS sends the
ACR the MS_Attachment_Req message to inquire about MS Capabilities and CS
Capabilities. The ACR sends the RAS a response containing the result for the
requested registration information. The RAS sends the MS the REG-RSP message.
The RAS sends the ACR the MS_Attachment_Ack message to explicitly provide
notification of the start time of the next procedure.
(14)~(19) To request DSA for Pre-Provisioned SF, the ACR sends the RAS the Path
Registration Request message containing the SFID field, Resource Description field
(SF/CS parameter), and Data Path ID (= GRE Key) field for setting a data path with
the RAS. The RAS receives this message, performs admission control, and then
sends the MS the DSA-REQ message. The MS sends the RAS the DSA-RSP
message containing the confirmation code as the result of the DSA-REQ message.
The RAS sends the ACR the Path Registration Response message containing the
data path ID to set a data path with the ACR. The ACR sends the RAS the Path
Registration Confirm message. The RAS sends the MS the DSA-ACK message.
(20)~(25) This procedure is used to assign an IP address to the MS when it uses PMIP.
If the MS requests the DHCP procedure to obtain an IP address, the ACR performs
the PMIP procedure.
(26)~(30) This procedure is used to assign an IP address to an MS when it uses CMIP.
If the MS directly requests MIT registration to obtain an IP address, the ACR operates
as an FA and assigns an MIP address to the MS in interoperation with the HA.
