Mobile WiMAX RAS SPI-2213 System Description/Ed.02

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.
