Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05

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)~(38) This is the procedure for allocating an IP address to the MS that uses the simple IP

method. If the MS requests the DHCP procedure to receive an allocated IP address, the

ACR performs the DHCP relay agent function to receive a simple IP address from the

external DHCP server and then sends the received IP address to the MS.

(39)~(40) When the Diameter protocol is used, it is notified that accounting has begun for the

service flow using the ACR/ACA message. When the RADIUS protocol is used, the

Accounting Request/Accounting Response message is used.
