CHAPTER 2. Overview of SPI-2213

2-12

Operator Authentication Function

The SPI-2213 provides the authentication and the permission management functions for the

operator who manages the Mobile WiMAX system. The operator accesses the SPI-2213 by

using the operator’s ID and password via Web-EMT or IMISH and the SPI-2213 assigns

the operation right in accordance with the operator’s level.

The SPI-2213 carries out the logging function for successful access, access failure and

Maintenance Function with Enhanced Security Function

For the security, the SPI-2213 supports Simple Network Management Protocol version 2c

(SNMPv2c) Simple Network Management Protocol version 3 (SNMPv3) and File Transfer

Protocol (FTP) in the communication with WSM and Hyper Text Transfer Protocol over

SSL (HTTPs) and Secure Shell (SSH) in the communication with console terminals.

On-line Software Upgrade

When a software package is upgraded, the SPI-2213 can upgrade the package while running

old version of software package. The package upgrade is progressed in the following

procedure: ‘Add New Package Æ Change to New package Æ Delete Old Package’.

In package upgrade, the service is stopped temporarily because the old process is

terminated and the new process is started in the ‘Change to New package’ stage.

However, since OS is not restarted, the service will be provided again within a few minutes.

After upgrading software, the SPI-2213 updates the package stored in a non-volatile storage.

In addition, the SPI-2213 can re-perform the ‘Change to New package’ stage to roll back

into the previous package before upgrade.

Call Trace Function

The SPI-2213 supports the call trace function for a specific MS. The SPI-2213 can carry

out the call trace function up to 10 MSs. If a call occurs in the MS that an operator

previously specified via ACR, the signaling message and statistical traffic data are

transmitted to WSM. Besides, the SPI-2213, also, sends the RF environment information,

such as Carrier-to-Interference-and-Noise-Ratio (CINR) for MS, Modulation and Coding

Schemes (MCS) level and Burst Error Rate (BER).

Detailed Information for Each Session and Service Flow (PSMR/PSFMR)

The Mobile WiMAX system of Samsung collects and stores detailed information of all

sessions (Per Session Measurement Record, PSMR) and detailed information of all service

flows (Per Service Flow Measurement Record, PSFMR) to provide it to an external log

server. When a session or service flow is created, the Mobile WiMAX system starts to

collect relevant information, and when the session or service flow terminates, the system

creates and stores a message in a file so that the external log server can collect the message.
