Classification Description
(1)~(2) The MS transmits the RNG-REQ message including its own MAC address and
the Ranging Purpose Indication to the RAS, and the RAS allocates the Basic &
Primary Management CID and transmits the RNG-RSP message to the MS.
(3)~(4) The MS transmits the SBC-REQ message to the RAS including the physical
parameter and the authorization policy information which it supports.
The RAS transmits the MS_PreAttachment_Req message to the ACR including
the authorization policy support via the Default IP address and the UDP port
number of the ACR.
(5)~(7) The ACR transmits the MS_PreAttachment_Rsp message to the RAS including the
supported authorization policy, and the RAS extracts the information received from
the ACR, attaches it to the SBC-RSP message and transmits it to the MS.
Then, RAS transmits the MS_PreAttachment_Ack to the ACR, and notifies the start
point of the next process(EAP transmission) explicitly.
(8) The procedure of the subscriber authentication between the MS and the AAA
server is performed, and when the authentication is successful, the ACR receives
the provisioned policy information for each subscriber from the AAA server.
For the detailed information, see ‘4.1.2 Authentication’.
(9)~(13) The MS transmits the REG-REQ message to the RAS including the registration
information(MS Capabilities, CS Capabilities, HO Support, etc), and the RAS
transmits the MS_Attachment_Req message to the ACR to inquire the
corresponding MS Capability and the corresponding CS Capability. The ACR
transmits the response to the RAS including the result of the requested
registration information, and the RAS transmits the REG-RSP message to the MS.
The RAS transmits the MS_Attachment_Ack to the ACR, and notifies the start
point of the next process explicitly.
(14)~(19) To request the DSA for the Pre-Provisioned SF, the ACR transmits the RR-
Request message to the RAS, including the SFID, the Resource Description
field(SF/CS parameter) and the Data Path ID(=GRE Key) field to set the data
path with the RAS. The RAS receives this message and performs admission
control for this, and then transmits the DSA-REQ message to the MS. The MS
attaches the Confirmation Code to the DSA-RSP message as a result of DSA-
REQ and transmits the message to the RAS, and the RAS transmits the RR-
Response message to the ACR including the Data Path ID to set the data path
with the ACR. Then the ACR transmits the RR-Confirm message to the RAS, and
the RAS transmits the DSA-ACK message to the MS.
(20)~(25) This is the procedure to allocate the IP address to the MS, which uses the PMIP,
if the MS requests the DHCP procedure to acquire the IP address, the ACR
performs the PMIP procedure.
(26)~(30) This is the procedure to allocate the IP address to the MS, which uses the CMIP,
if the MS requests the MIP registration directly, the ACR operates as the FA and
interworks with the HA and allocates the MIP address to the MS.
(31)~(32) The start of accounting process for the service flow created in the stages of (14)
to (19) is notified to the AAA server.
