RNC Operation and Management Server (OMS)

Operation and Management Server (OMS) is a Linux OS based

management server in RNC, which is connected to the
Telecommunications Management Network of WCDMA.

OMS provides O&M data mediation, concentration and aggregation

functionality in 3G WCDMA RAN and in RNC.
RU
OMS is used for local, RNC-level changes that are made for one 2
be 0RNCa
at
fo nd to
a time and for mediation in NetAct originated changes that are targeted
managed objects under the control of the RNC. re

NetAct Framework is used for network-level changes, targeted to several

RNCs.

RNC OMS HW Platform
The RN5.0 introduces the new standalone OMS HW. This OMS variant uses the commercial IT server HW:
HP DL360 Proliant.
• The new standalone RNC OMS HW comes with:
HP Proliant DL360 Generation 6 of
• Quad core Nehalem Intel processors
• Min 8 GB memory (scalable up to 128 GB)
• Mirrored hard discs (from 2 up to 6 x 146GB HDD)
• Dual port network card(100 Mbit/1Gbit)
• SCSI card for external devices like data tapes and magneto-optical
• Optional IP Sec extension
• USB 2.0 ports
• Height 1U

• The Integrated RNC OMS, old legacy HW comes with:

• MCP18-B B01 plug-in unit of
• Intel Dothan 1.8 GHz
• Single core processor
• Max 4GB memory
• 2 SCSI disks of either 73GB or 146GB (only in RN5.0)
• Dual port network card(10/100Mbit)

RNC OMS SW Platform

RU20/RN5.0 RNC OMS application SW is

based on NSN Flexiplatform that provides:

• EM, SW Mgmt & Commissioning support

• Basic O&M and messaging services
• Base platform services with OS &
HW adaptation

RNC OMS Operating System (OS)
The RN5.0 OMS uses OS provided by the underlying NSN Flexiplatform.
• Red Hat Enterprise Linux (RHEL) version 4
• Components are installed utilizing RPM files (Red Hat Package Management)
• Integrated OMS (MCP18-B) uses 32bit SW release / standalone OMS (HP Proliant) uses 64bit SW rel
• The operating system (OS) delivery is one part of the Flexiplatform base platform services together with
other important components such as backup, hardware and software management, and the high
availability services (HAS) middleware.
• The FlexiPlatform Linux distribution is not completely identical to the Red Hat Linux distribution.
• Many RPMs that are not needed by the FlexiPlatform and its applications, but are normally contained in
standard Red Hat Enterprise Linux, have been removed. This reduces the size of operating system and
removes potential vulnerabilities.
• Currently, the number of different Linux OS SW packages included in the FlexiPlatform OS installation
package has been reduced to roughly one-seventh of the original number of SW packages included in
Red Hat Enterprise Linux Release distribution.
• In addition to the RPMs selected from the Red Hat Distribution, the system contains roughly 100 RPMs
provided by Nokia Siemens Networks to add functionality to the system. The exemplary enhancements
provided by the mentioned RPMs include:
• the watchdog feeder subsystem WDMana
• network link monitor for automatic LAN failover support

EM users for whom sufficient user rights (permission to modify) have been
granted using the User Authority Manager application, are able to terminate
sessions of other EM users as well, for example in cases where maintenenace

BTS Performance Management data transfer
• OMS collects measurement data directly from the WBTS using O&M interface.
BTS Licence Management
• The LM operation (download, upload, delete and status query) uses BTS O&M mediation to mediate
