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.00 4.1.6 Handover Inter-RAS Handover The following is the inter-RAS handover procedure.
CHAPTER 4. Message Flow Classification Description (1)~(3) 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.00 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 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 RAS SPI-2213 System Description/Ed.00 Classification (1)~(5) 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. (6)~(15) FA relocation is triggered, and the registration of the PMIP or the CMIP is processed.
CHAPTER 4. Message Flow Classification (1)~(3) Description If the power of the Awake Mode MS is turned off, the MS transmits the DREG-REQ message including ‘Deregistration code=0’ to the RAS, and the RAS notifies the ACR of this. (4) ACR release the MIP related information with HA. (5)~(6) The ACR notifies the RAS of the result of power down processing, and release the data path.
Mobile WiMAX RAS SPI-2213 System Description/Ed.00 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.00 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), MRAF(Digital I/Q and C & M: Optic) and RET controller of MMA-G.
CHAPTER 5. Additional Functions and Tools 5.2 Web-EMT The Web-EMT is a type of GUI-based consol terminals and the tool to access the SPI-2213 directly, monitor the device status and perform operation and maintenance. An operator can execute the Web-EMT only with Internet Explorer and the installation of additional software is not necessary. In addition, GUI is provided in HTTPs protocol type internally.
