CHAPTER 3. Outdoor SPI-2331 Architecture
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.
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 outdoor SPI-2331, 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 802.16e
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 outdoor SPI-2331.
