Mobile WiMAX Indoor RAS SPI-2210 System Description/Ed.07 Classification Description (1) When the MS is changed into the Idle Mode, it creates the DREG-REQ message and transmits it to the RAS, and the value of the De-Registration Request Code field is set as 0 x 01.
Mobile WiMAX Indoor RAS SPI-2210 System Description/Ed.07 Awake Mode Sleep Mode The Awake Mode and the Sleep Mode of the MS can be classified only by the RAS, and the ACR does not classified the two kinds of status, and recognizes and manages both of them as the Awake Mode. MS RAS ACR Awake 1) MOB_SLP-REQ 2) MOB_SLP-RSP Sleep DL Traffic 3) MOB_TRF-IND 4) BW Request Header Awake Figure 4.
Mobile WiMAX Indoor RAS SPI-2210 System Description/Ed.07 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 Indoor RAS SPI-2210 System Description/Ed.07 (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 Indoor RAS SPI-2210 System Description/Ed.07 4.1.4 Location Update Inter-RAS Location Update The following is the location update procedure when the MS moves to other paging group in the same ACR.

Mobile WiMAX Indoor RAS SPI-2210 System Description/Ed.07 Inter-ACR Location Update (Anchor Relocation) When the MS in the Idle mode moves to other ACR area, the Inter-ACR Location Update (LU) procedure is performed. At this time, the procedure is different depending on whether the MIP-based CMIP/PMIP method or the simple IP method is used.
Mobile WiMAX Indoor RAS SPI-2210 System Description/Ed.07 Classification (1)~(2) Description If the paging group is changed, the MS transmits the RNG-REQ message including the MAC address, the Location Update Request and the Paging Controller ID to a new T-RAS (Target RAS). The T-RAS transmits the Location Update Request message including the Paging Controller ID to its own default ACR.
Mobile WiMAX Indoor RAS SPI-2210 System Description/Ed.
Mobile WiMAX Indoor RAS SPI-2210 System Description/Ed.07 Classification (1)~(2) Description At this time, the procedure is different depending on whether the MIP-based CMIP/PMIP method or the simple IP method is used. When the paging group is changed, the MS sends the new T-RAS (Target RAS) an RNG-REQ message including the MAC address, Location Update Request and Paging Controller ID in order to request a location update.
Mobile WiMAX Indoor RAS SPI-2210 System Description/Ed.07 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 Indoor RAS SPI-2210 System Description/Ed.07 4.1.6 Handover Inter-RAS Handover The following is the inter-RAS handover procedure.
Mobile WiMAX Indoor RAS SPI-2210 System Description/Ed.07 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 Indoor RAS SPI-2210 System Description/Ed.07 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 Indoor RAS SPI-2210 System Description/Ed.07 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 Indoor RAS SPI-2210 System Description/Ed.07 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 Indoor RAS SPI-2210 System Description/Ed.07 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. The T-ACR completes the Authenticator Relocation procedure by notifying the S-RAS of the authentication result. (8)~(9) S_ACR sends MS context information to T_ACR.
