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

On-line Software Upgrade

When a software package is upgraded, the indoor SPI-2210 can upgrade the package while

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

procedure: ‘Add New Package  Change to New package  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 indoor SPI-2210 updates the package stored in a non-volatile

storage.

In addition, the indoor SPI-2210 can re-perform the ‘Change to New package’ stage to roll

back into the previous package before upgrade.

Call Trace Function

The indoor SPI-2210 supports the call trace function for a specific MS. The indoor SPI-

2210 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 indoor SPI-2210, 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.

The information collected by the ACR includes session termination time, initial and final

handover information (handover types, cell information), and the MAC address and IP

address allocated to the MS. The RAS collects such information as MS MAC addresses,

continued session time, continued service flow time, turnaround time for network entry,

CID, SFID, initial and final wireless quality information (RSSI, CINR, Tx power), and

throughput information.

The ACR deliver the information collected by ACR to the RAS, and the RAS creates and

stores a file for each period.

Threshold Cross Alert (TCA) Control

The indoor SPI-2210 defines under/over threshold for statistics. When a statistical value

collected at Bucket Interval (15, 30, and 60 minutes) is lower than the under threshold, it

generates an under TCA alarm. When the value is higher than the over threshold, it

generates an over TCA alarm. The alarms are reported to the WSM. TCA can enable or

disable details of each statistical group and set a threshold per severity.
