Mobile WiMAX RAS SPI-2213 System Description CHAPTER 4. Message Flow 4.1 Call Processing Message Flow 4.1.1 Initial Access The following is the procedure to set the Provisioned Service Flow (SF) of the networkinitiated Dynamic Service Add (DSA) mode in the process of the initial network entry.
CHAPTER 4.
Mobile WiMAX RAS SPI-2213 System Description/Ed.02 Classification (1)~(2) Description 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.
CHAPTER 4. Message Flow (Continued) Classification (31)~(38) Description 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.
Mobile WiMAX RAS SPI-2213 System Description/Ed.02 Classification Description (0)~(2) When the ACR receives MS_PreAttachment_Req_Ack for SBC-RSP from the RAS, the ACR includes the EAP Request/Identity payload in the AuthRelay-EAPTransfer message and transmits the message to the RAS to start the EAP authentication. The RAS relays the received EAP payload to the MS by using the PKMv2 EAP-Transfer/PKM-RSP message.
CHAPTER 4. Message Flow 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 RAS SPI-2213 System Description/Ed.02 4.1.3 Status Change Awake Mode Æ 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 Æ 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.
CHAPTER 4. Message Flow (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 RAS SPI-2213 System Description/Ed.02 Idle Mode Æ 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.
CHAPTER 4. Message Flow (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 RAS SPI-2213 System Description/Ed.02 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. RAS 1 (PG 1) MS RAS 2 (PG 2) ACR 1) MOB-PAG_ADV 1) MOB-PAG_ADV 2) RNG-REG (Location Update Request, Paging Controller ID) 3) LU Request 4) LU Response 5) RNG-RSP (Location Update Response) 6) CMAC_Key_Count_Update 7) CMAC_Key_Count_Update_Ack 8) LU Confirm Figure 4.
CHAPTER 4. Message Flow MS T-RAS T-ACR 1) RNG-REQ 2) LU Request 3) LU Request 6) RNG-RSP 5) LU Response 4) LU Response 7) CMAC_Key_Count_Update S-ACR AAA HA 8) CMAC_Key_Count_Update 10) CMAC_Key_Count_update_Ack 9) CMAC_Key_Count_update_Ack 11) LU Confirm 12) PC_relocation_Ind 13) PC_relocation_Ack 14) LU Confirm 15) Relocation Notify 16) Relocation Notify Ack 18) MOB_PAG-ADV 17) MS Paging Announce (0b10 Enter Net.
Mobile WiMAX RAS SPI-2213 System Description/Ed.02 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.
CHAPTER 4.
Mobile WiMAX RAS SPI-2213 System Description/Ed.02 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.
CHAPTER 4. Message Flow 4.1.5 Paging Paging can be classified into the following two types. y 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 RAS SPI-2213 System Description/Ed.02 4.1.6 Handover Inter-RAS Handover The following is the inter-RAS handover procedure.
CHAPTER 4. Message Flow 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 RAS SPI-2213 System Description/Ed.02 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.
CHAPTER 4. Message Flow 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). (5)~(11) The T-RAS sends the ACR an HO-Response message including its own capability information.
Mobile WiMAX RAS SPI-2213 System Description/Ed.02 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.
CHAPTER 4. Message Flow 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.
Mobile WiMAX RAS SPI-2213 System Description/Ed.02 4.1.7 Access Termination Access Termination (Awake Mode) The following is the procedure that the access is terminated because the power of the Awake Mode MS is turned off.
CHAPTER 4. Message Flow Access Termination (Idle Mode) The following is the procedure that the access is terminated because the power of the Idle Mode MS is turned off. RAS MS ACR AAA HA 1) RNG-REQ (Location Update Request, Paging Controller ID) 2) LU Request 3) LU Response 4) RNG-RSP (Location Update Response) 5) LU Confirm 6) MIP release 7) Diameter: STR/RADIUS: Accounting Request stop 8) Diameter: STA/RADIUS: Accounting Response stop Figure 4.
Mobile WiMAX RAS SPI-2213 System Description/Ed.02 4.2 Network Synchronization Message Flow The SPI-2213 uses GPS for the system synchronization. The UCCM of the MMA-G, which is the GPS reception module, creates the clock with the clock information received from a GPS and then distributes the clock to each hardware module in the SPI-2213.
CHAPTER 4. Message Flow 4.3 Alarm Signal Flow The detection of failures in the SPI-2213 can be implemented by hardware interrupt or software polling method. The failures generated in the SPI-2213 are reported to the management system via the SNMP trap message. Failure Alarm Types y System Failure Alarms Time Sync Fail, Fan Fail, Temperature High, etc. y Board Failure Alarms − Hardware Failure Alarms: FUNCTION FAIL, BOARD DELETION, etc.

CHAPTER 4. Message Flow 4.4 Loading Message Flow Loading is the procedure to download the software execution files and the data from the IS, which are required to perform each function of each processor and each device of the SPI2213. Loading the SPI-2213 is performed in the procedure of initializing the system. In addition, if a specific board is mounted on the system or the hardware is reset, or if the operator of the upper management system reboots a specific board, loading is performed.
Mobile WiMAX RAS SPI-2213 System Description/Ed.02 Loading Message Flow After performing the pre-loading procedure, if the method of loading is determined, the Main OAM (ULM) of the MMA-G which performs the operation and the maintenance of the entire SPI-2213 performs loading by using the FTP/SFTP to the corresponding IS (remote ID or its own storage). Then, the Main OAM (ULM) becomes the internal image server for the lower board and performs the loading procedure.
CHAPTER 4. Message Flow 4.5 Operation and Maintenance Message Flow An operator can check and change the status of the SPI-2213 by means of the management system. To this end, the SPI-2213 provides the SNMP agent function. The function enables the WSM operator to perform the operation and maintenance function of the SPI-2213 at remote site by using the SNMP.
Mobile WiMAX RAS SPI-2213 System Description CHAPTER 5. Additional Functions and Tools 5.1 RET The SPI-2213 can support the RET function by connecting an antenna with an AISG 2.0 interface and an RRH with an AISG 2.0 interface. To provide the RET function, the SPI-2213 sends and receives control messages to and from the WSM through the RET controller within the RRH (AISG2.0 interface), MRA-F (Digital I/Q and C & M: Optic) and RET controller of MMA-G.
CHAPTER 5.
