Software Structure of BSC6900
OMU software
The OMU software runs on the OMUa/OMUb board and handles the O&M functions of the
BSC6900. It consists of the operating system and the OMU applications. Operating system: For the newly delivered product, the Dopra Linux operating system is used.
For the inventory sites where the upgrade is required, both Suse Linux and Windows are
supported. OMU application: The OMU application runs above the underlying operating system. It
provides various processes such as LMT process, fault diagnosis process, authentication
process, and so on.
The Web LMT is a part of the OMU applications. With the GUI-based Web LMT, users can
operate and maintain the BSC by running MML commands. The functions such as alarm
query, message tracing, performance monitoring, and device maintenance can be performed.
The LMT is totally web-based, which means no installation is required. You can use a web
browser directly to log in to the Web LMT.

Software Structure of BSC6900
The biggest difference between the BSC6900 and BSC6000 is that in BSC6900 one
process is changed to multiple processed, thus improving performance and reliability.
BSC6900 BSC6000
OMU applications
The OM processes of the BSC6900 are different from the BSC6000. The BSC6900 OM processes include host_gate, ems_gate, authority, configure, maintain, stat, alarm, software, ftp_server, sntp, btsom, ems_agent, omu_manager, and Weblmt. Each process can run independently and perform the functions such as BSC/BTS configuration, maintenance, software management, and NMS interfacing. Each service board also has a maintenance software module, which works together with the OM processes in the OMU to maintain the objects related to the service board.
The OM processes of the BSC6000 include Omulocal and Omucore.Omucore is responsible for alarm handling, configuration and maintenance handling, Bin interfacing, event management, and so on.Omulocal is responsible for the OM of the BTS. It performs the functions such as BTS routine maintenance, BTS software loading, BTS alarm conversion, and BTS test. The LMT communicates with the GBAM/GOMU based on TCP/IP and FTP, and with the M2000 based on UDP.

The management of the OMU is achieved through the coordination of the service processes within the OMU.
The service processes of the OMU are shown in the figure.

Installation and upgrade scenarios: 1. New site
If the delivered OMU has the OMU operating system and OMU applications, you can use the upgrade tool to
upgrade the OMU applications and host software after completing the IP settings.
Documents: OMU Administration Guide > Installing the OMU Applications in Field Commissioning, Upgrade
Guide, Commissioning Guide 2. Troubleshooting in maintenance scenarios
If the OMU operating system or OMU applications need to be reinstalled on the site, there is no need to
change the host software.
Document: OMU Administration Guide > Reinstalling Software on Site 3. Upgrade
It involves version upgrade, patch upgrade, and version plus patch upgrade.
If the target version is V900R011C00SPCX00, the version upgrade needs to be performed; if the target
version is V900R011C00SPCXY0, you should determine whether the baseline version is the same as the
current version. If the baseline version is the same as the current version, a patch needs to be installed.
Otherwise, the current version needs to be upgraded to the baseline version and a patch needs to be
installed. (X indicates the baseline version, and Y indicates a cold patch.)

Software Structure of BSC6900 OMU IP addresses
You can set the OMU IP addresses by logging in to the OMU locally or by creating
the USB installation disk. Document: OMU Administration Guide > Working Principles of the OMU
Note: bond1 and bond1:0, vlan1 and vlan1:0, or fixed IP address and virtual IP
address are not fixedly matched.
IP Address MeaningConfiguration
SuggestionExample
Internal fixed IP address
Used for the communication between the active OMU and the standby OMU in the internal network segment. It is configured when the OMU operating system is installed.
No modification is required for single OMU
ifconfig vlan1
External fixed IP address
Used for the communication between the active OMU and the standby OMU in the external network segment. It is configured when the OMU operating system is installed and floats between the two external Ethernet adapters of the OMU board.
Network planning ifconfig bond1
Internal virtual IP address
Used for the communication between the active OMU and the BSC6900 host boards. It exists on the internal Ethernet adapter team and is added automatically when the OMU applications are started. Not modified generally ifconfig vlan1:0

Policy of Using the OMU Operating System
Policy of using the OMU operating system Inventory upgrade: The upgrade can be performed by directly using the
early operating system. For the upgrade from BSC6810 to BSC6900, the original Windows operating
system can be used.
For the upgrade from BSC6000 to BSC6900, the original SUSE Linux operating
system can be used.
Note: The root directory of Dopra Linux is /mbsc, while that of Suse Linux is
/BSC6000/data/mbsc.
Pay attention when getting the files. Later, such difference will be hidden.
New deployment: For the newly deployed product, Dopra Linux is used.
Dopra Linux is the Linux operating system developed by Huawei. It is characterized
by small footprint, easy and fast installation, and high security.

Uploading OMU Installation Package to OMU
Background information The installation package of OMU applications is saved in the directory \Software\setup of the
version software package. It must be uploaded to the directory \mbsc\upgrade of the OMU.
The installation package of OMU applications must be named by version number. That is,
after the installation package of the OMU applications is uploaded to the OMU, the directory
structure should be: \mbsc\upgrade\V900R011C**.
Operation steps: Log in to the OMU using psftp, and switch to the local directory that saves the
version files.
Enter ls /mbsc/upgrade to check whether the installation directory exists in the
OMU. If the directory /mbsc/upgrade does not exist, enter mkdir /mbsc/upgrade
to create the installation directory in the OMU.
Enter cd /mbsc/upgrade to switch to the OMU installation directory.
Enter put -r V900R011C00 to perform the file uploading.

BSC6900 Upgrade Scenarios
Upgrade of BSC6900 software Upgrade methods:
Upgrade tool
M2000: the upgrade tool is activated through the M2000
Upgrade scenarios: upgrade, patch installation, upgrade plus patch installation, upgrade rollback, and
patch rollback
Support for batch upgrade:
In batch upgrade, one client is connected to multiple BSCs at the same time for the upgrade of
multiple BSCs. The client provides the configuration GUI and the GUI of viewing the upgrade progress
for each BSC. The BSC upgrade process in each client does not interfere with each other. In terms of
design, there is no restriction on the maximum number of BSCs during batch upgrade.
The client of the upgrade tool is saved in the directory \remoteclient. The external virtual IP address or
fixed IP address can be used for the upgrade operations. You can perform software uploading, one-key
operations, and troubleshooting easily through the client.
The server of the upgrade tool is saved in the directory upgrade. You can use remoteclient to start the
UpgradeServer.exe process.
HUAWEI TECHNOLOGIES Co., Ltd. Page 31HUAWEI Confidential
Installation and Upgrade of BSC6900 Software
Active and standby work areas The active and standby work areas are used for the upgrade and rollback of BSC6900 versions,
enabling fast switch between different versions. The relation of the active and standby work areas is
relative, depending on the current running version. That is, the work area saving the versions files
of the current version is the active work area and the other work area is the standby work area. Pre-upgrade
Before upgrade, the pre-upgrade can be performed. It involves the operations such as checks
before the upgrade and data upgrade.
Data upgrade rule In special data upgrade scenarios, a customized upgrade rule should be defined and configured.
Generally, the default data upgrade rule is used.
The default upgrade rule is identified by the original version number and target version number.
Intermediate version The upgrade can be performed only when there is a corresponding upgrade rule. If an intermediate
version is required, but there is no corresponding upgrade rule, an intermediate version must be
provided. Thus, the old version can be upgraded first to the intermediate versions and then to the
new version. The intermediate version number is in the same format as the old version number.
