Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05 (Continued) Classification (12)~(16) Description When the authentication is successfully completed, the ACR receives the Master Session Key (MSK) that is the upper key to provide security and provisioned policy information per subscriber from the AAA server using the Diameter EAP Answer (DEA) message (when the Diameter protocol is used) or the AccessAccept message (when the RADIUS protocol is used).
Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05 At the Time of Authenticator Relocation When the MS performs the CSN-anchored Handover (HO), or the Idle Mode MS moves to another ACR area and performs the location update, the following re-authentication procedure is performed to move the authenticator from the existing Serving ACR to the Target ACR.
Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05 4.1.3 Status Change Awake Mode Idle Mode If the data traffic is not transmitted/received for a certain time, the status of MS is changed from the Awake Mode to the Idle Mode. Sleep Mode Idle Mode Change The MS of the Sleep Mode is not changed into the Idle Mode, immediately. Before being changed from the Sleep Mode into the Idle Mode, the MS is changed to the Awake Mode, first, and then, after requesting DREG, it is changed into the Idle Mode.
Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05 (Continued) Classification Description (6)~(8) If the Network re-entry from the MS is not transmitted until the Idle Resource Retain timer expires, the RAS performs the Data Path (DP) Release procedure with the ACR. (9)~(10) As the MS has been transited to Idle mode, an accounting end message is sent to the AAA server to update the accounting information using the ACR/ACA message (if the Diameter protocol is used).
Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05 Idle Mode Awake Mode (QCS) When an MS in Idle Mode responds for the paging because of incoming traffic or sends the traffic, the status of MS is changed from the Idle Mode into Awake Mode. In both cases, the MS should perform the network re-entry procedure to change the status into the Awake Mode and the Mobile WiMAX system of Samsung basically takes account of the QCS procedure as the network re-entry method.
Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05 (Continued) Classification (9) Description The ACR receives the Path Registration Ack message and is notified of data path set results. (10) If an MS receives RNG-RSP, the MS transmits BW Request Header to notify the system that the status is changed into the Awake Mode.

Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05 4.1.5 Paging Paging can be classified into the following two types. The RAS broadcasts the MOB_PAG-ADV message periodically and notifies the MS of the corresponding paging group. The MS is changed into the Idle Mode and checks if the paging group of the MS is changed by checking the MOB_PAG-ADV message periodically based on the paging information (Paging Cycle, Paging Offset, PGID) received from the system.
Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05 4.1.6 Handover Inter-RAS Handover The following is the inter-RAS handover procedure.
Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05 Classification (1)~(3) Description The MS transmits the MOB_MSHO-REQ message including the Neighbor BS (RAS) ID and the parameter related to handover to the current Serving RAS (S-RAS) to request handover. The S-RAS transmits the HO-Request message including the received MOB_MSHO-REQ parameter and the context information to the ACR, and the ACR forwards the HO-Request message to the Target RAS (T-RAS).
Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05 Inter-ASN Handover: ASN-Anchored Mobility Inter-ASN handover is divided into the ASN-anchored mobility method via the R4 interface and the CSN-anchored mobility method via the R3/R4 interface. The following figure indicates the inter-ASN handover procedure of the ASN-anchored mobility method, the Serving ACR (S-ACR) performs the anchor function.
Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05 Classification (1)~(4) Description The MS, in order to request a handover, sends the S-RAS (Serving RAS) an MOB_MSHO-REQ message including the neighbor BS (RAS) ID and handoverrelated parameters. The S-RAS sends the ACR an HO-Request message including the received MOB_MSHO-REQ parameters and context information. The ACR forwards the HO-Request message to the T-RAS (Target RAS).
Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05 Inter-ASN Handover: CSN-Anchored Mobility The following is handover of the CSN-anchored mobility method among the types of interASN handover, the anchor function is relocated from the Serving ACR (S-ACR) to the Target ACR (T-ACR). CSN-anchored mobility is composed of the process that Authenticator/DPF Anchor is relocated to the target ACR after ASN-anchored mobility handover is performed.
Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05 Classification (1)~(7) Description This is the procedure to relocate the Authenticator from the S-ACR to the T-ACR, the T-ACR triggers in order that the MS performs the EAP authentication procedure with the AAA server again.
