User's Manual

Mobile WiMAX Indoor RAS SPI-2210 System Description/Ed.07

Device Driver (DD)

DD manages the normal operation of applications that OS does not control in the system.

DD provides the API for the user processor to setup/control/detect the hardware device.

Also, DD confirms the device configuration by receiving the configuration data from the

upper user processor, and also provides the functions of register manipulation for device

operation, device diagnosis, statistics and status management.

Network Processor Software (NPS)

NPS manages the innate functions of Network Processor (NP) that mainly processes the

packets, and it connects the upper processor and NP in Board Processor (BP), and provides

the functions of NP message processing, NP statistics data collection and report.

IP Routing Software (IPRS)

IPRS executes the IP routing protocol function. IPRS collects and manages the system

configuration and status data necessary for IP routing operation, and based on the data, it

generates the routing table via the routing protocol, and makes packet forwarding possible.

Call Control (CC)

CC is a software subsystem that processes the calls in the indoor SPI-2210, and CC

interfaces with MS and ACR. CC supports data exchange function to support wireless data

service such as the MAC scheduling, air link control, ARQ processing and IEEE 802.16

message processing.

Operation And Maintenance (OAM)

The OAM provides the interface (SNMPv2c or SNMPv3, SFTP, HTTPs, SSH) of which

the security is strengthened, and which is standardized to interwork with the upper

management system such as the WSM, the Web-EMT and console terminal based on the

IMISH.

In addition, this performs the functions of initializing and restarting the system, processing

the call, collecting the statistics for various performance data, managing the system

configuration and resources, managing the status of the software resources and the

hardware resources, managing the failure and performing the diagnostics for the operation

and the management of the indoor SPI-2210.
