Chapter 22 BSC6800 Upgrade Tool

22.1 Introduction

22.1.1 Definition

The BSC6800 upgrade tool can be used for remote and push-button upgrade of the Radio Network Controller (RNC).

The BSC6800 upgrade tool is applicable to upgrading the following objects:

BAM servers Board software and data on boards

Figure 22-1 shows the network topology for the BSC6800 upgrade tool.

RNC host

BAM_UPPER

BAM_LOWER

LAN

Upgrade client

Figure 22-1 Network topology for the BSC6800 upgrade tool

The elements in Figure 22-1 are described as follows:

Upgrade client: client on which upgrade personnel perform upgrade operations BAM_UPPER: one of the two BAM servers that the Wideband Code Division

Multiple Access (WCDMA) RNC uses BAM_LOWER: the other BAM server that the WCDMA RNC uses RNC host: host of the RNC

22.1.2 Purposes

Without the BSC6800 upgrade tool, maintainers must perform the upgrade at night due to the complex upgrade process. The tool helps reduce work load and avoid fatigue-induced mistakes, thus improving the availability of the RNC in terms of upgrade.

The RNC boasts higher availability in the following ways:

Enabling remote control

The maintainer controls the upgrade remotely on the upgrade client. No manual operation is necessary on site.

Enabling automatic upgrades

The tool combines the upgrade steps together to fulfill the push-button upgrade, thus simplifying the upgrade.

Improving time efficiency

All upgrade steps are scheduled and performed automatically without operator intervention. The whole process takes about 90 minutes, which is a great progress in time efficiency compared with the manual upgrade.

Improving upgrade reliability

The push-button upgrade process reduces the error rate.

Providing detailed upgrade reports

The tool generates a detailed report at the end of each upgrade phase. The reports state the upgrade process clear.

Supporting version rollback

The tool supports version rollback in case of upgrade failure. This ensures the proper operation of the system.

Product Version

RNC BSC6800 V100R005 and later releases

22.2.3 Miscellaneous

None.

22.3 Impact

22.3.1 On System Performance

The upgrade may pose the following impact on the system performance:

Exceptions, for example, network errors, may occur to the upgrade. When failures occur during the upgrade, operator intervention or manual

troubleshooting or completion is necessary.

22.3.2 On Other Features

None.

22.4 Technical Description

22.4.1 Functions of the BSC6800 Upgrade Tool

The BSC6800 upgrade tool provides the following functions:

Checking data before the upgrade

The data includes the following:

– Operating system– BAM database– BAM software– User-input data

Upgrading BAM servers

The upgrade covers the BAM software and data on the BAM servers.

Upgrading boards

The upgrade covers the software for and data on the WCDMA RNC Switch Subrack (WRSS) and WCDMA RNC Business Subrack (WRBS).

22.4.2 Ways to Obtain the BSC6800 Upgrade Tool

The BSC6800 upgrade tool is provided with the BAM software.

For example, if the delivered BAM software version is V100R006C010B060, the tool is stored under \V100R006C010B060\upgrade. For details, refer to the upgrade guide.

22.4.3 Principles for the BSC6800 Upgrade Tool

The BSC6800 upgrade tool combines the upgrade steps in sequence based on the three phases to fulfill the automatic upgrade.

In addition, the tool enables remote upgrades by separating execution and display.

22.4.4 Internal Upgrade Process for the BSC6800 Upgrade Tool

The BSC6800 upgrade tool is of two parts: server upgrade and client upgrade.

Figure 22-2 shows the internal upgrade process for the tool.

Start

Checks data on the active and standby BAM server

Upgrades the standby BAM server

Switches over the active and standby BAM servers

Loads data to the boards and restart the boards

Upgrades the other BAM server

Checks the software version

End

Figure 22-2 Internal upgrade process for the tool

The internal upgrade process for the tool is described as follows:

1) After the upgrade client starts up, the upgrade server checks data on the active and standby BAM servers before the upgrade.

2) The tool upgrades the standby BAM server.3) The tool switches over the active and standby BAM servers.4) The tool loads data to the boards and restarts the boards.5) The tool checks the software version.

6) The tool upgrades the other BAM server.

The upgrade is complete.

22.4.5 Working Modes of the BSC6800 Upgrade Tool

Use the BSC6800 upgrade tool to upgrade the RNC.

The tool works in the following two modes:

Standard mode

In standard mode, all steps are performed automatically.

Step-by-step mode

In step-by-step mode, the steps are performed one by one. The user can choose to perform or skip a step or to cancel the upgrade at any step.

Caution:

The step-by-step upgrade is applicable only to those who are familiar with upgrade details. Ordinary users are recommended to perform the upgrade in standard mode.

Figure 22-1 shows the procedure for the upgrade by tool.

Start

Get software ready

Start the upgrade client

Complete configuration data through the wizard

Prepare for the upgrade

Check the upgrade

Execute the upgrade

End

Upgrade the other BAM server

Figure 22-1 Procedure for the upgrade by tool
