 OMM
i The OMM is a necessary part of the NE.

ii The OMM manage network elements in the TMN. In addition to configuration
management, performance management, fault management and security
management required by the TMN, the OMM also provides topology
management, system management, and tools, to maximally facilitate local
operation and maintenance. Each OMM manages one network element.
iii As the man-machine interface of the OMM, the local management terminal
(LMT) can be placed locally, or act as remote management terminal (RMT) to
perform remote operation and maintenance through E1, X.25, DDN or
common dial-up mode.
iv The OMM adopts the internal interface to communicate with the NE, and Qx
interface to communicate with the NMC.
v The OMM layer can manage a variety of NEs such as MSC/VLR, HLR/AUC,
BSS, PDSN, AAA, MSCe, MGW, etc.
 NMC
i In addition to the OMM function, the NMC supports the CDMA Network
Optimization (CNO2) that can manage, monitor, as well as make statistics and
analysis of NEs in a centralized manner.
ii Each NMC can manage multiple OMMs, and through the cascade, one upper-
level NMC can manage multiple lower-level NMCs.
iii The NMC adopts the Qx interface to communication with the OMM, and the
TCP/IP, E1/T1, SDH, X.25 and DDN to connect to the OMM.

 Platform Makeup
i Hardware of the CDMA OMC consists of the server, disk array, client, alarm
box, switch, router, and server rack. The optional devices include printers,
sound boxes, and backup equipment.
ii The server usually adopts HP, DELL and IBM rack-mounted PC server, or
SUN Solaris server.
iii The CDMA OMC operating system and database platform is Windows + SQL,
or Solaris + Oracle.
 Hardware Reliability
i The CDMA OMC adopts advanced reliability technology for its hardware
structure. The important OMC servers use RAID technology to achieve hot
backup of data and reliable running of the system, and to ensure integrity of
system data.
 In view of many processes/threads during software operation of the system, it
is required the processor should have high concurrent performance and
loading capability. Therefore, the system hardware adopts multiple processors
to handle load balancing. Meanwhile, when a processing unit has any fault,
other processors can ensure uninterrupted normal work.
 The server power has redundancy backup, so when a power supply unit has
any fault, other units can continue supporting normal work of the system and
send out hardware alarms to the occurring faults (alarm indicator and sound
indicator). Also, the server rack supports dual-power redundancy to ensure
continuous operation of the server.
 To ensure network security, prevent message storm and implement network
isolation, the OMC system adopts a router for connection.

 System software supports dual-host active/standby mode. In the event of the
active server failure, network disconnection, or power off, the standby server
can take over the software task in time and ensure service continuity and high
availability.

4 Software Introduction
In terms of function, software structure of the NetNumen™ M3 (CDMA OMC) is divided
into the work station function (WSF), management application function (MAF), element
mediator function (EMF), platform support function (PSF), and NE foreground and
background agent. It can access the upper-level integrated NMS (Network Management
System) via CORBA, SNMP, and FTP, etc.
Many key modules of the CDMA OMC system adopt the load control design while its
software design adopts the error tolerance design widely; besides data adopt distributed
storage structure on a whole. All these ensure reliable operation of the system.

 NE
NE refers to a variety of managed network equipment including MSC/VLR,
HLR/AUC, BSS, PDSN, AAA, MSCe, and MGW.
 PSF
The CDMA OMC is based on the platform structure. A mature network management
platform can be constructed to implement 70% of the OMC software function. Upon
this platform, network management software for each product is developed to
implement only 30% of the function at the application layer. The platform strategy
ensures accumulation and reuse of technologies and experience, as well as fast
practicability and stability of products.

 EMF
The EMF is responsible for information conversion between the NE and the MAF.
As the existing ZXC10 NE series offer different interfaces, it is necessary for the
EMF to conduct information conversion between the foreground NE and the
background OMM. The EMF is connected to the NE or the MAF via the internal
interface. In order for different type of NEs to access the MAF for unified processing,
the EMF adopts the NE-related protocols to conduct the conversion.
 MAF
The MAF acts as a manager in the system management.
The MAF processes information related to NE management application. It supports
and controls NE management function, which involves processing original data,
generating value-added data such as data centralization, alarm modification,
statistics and performance analysis, and responding to the received information.
Also, the MAF supports WSF, which involves data acquisition and manipulation,
activity activation and confirmation, as well as event and notice transfer.
 GUI Client
The GUI client provides F and G interfaces defined in the TMN. On the one hand,
the WSF module is connected with the server via the F interface to collect and send
user operation commands, and on the other hand, it accurately resolves information
sent from the server via the G interface and presents it in user-friendly GUI mode to
the network management personnel.
There are many GUI clients at the same level of the OMC that can manage and
monitor the background system simultaneously.
 CLI Server
The CLI server supports Telnet access, completes conversion from the Telnet user
command to the F interface, resolves information returned at the G interface, and
presents it to the user.
 CLI Client
The CLI client provides the user with Telnet access. The user can log onto the
system to access system functions via any Telnet program. The system supports
simultaneous operation of many CLI clients.
 Northbound interface
Based on the 3GPP/3GPP2 standards, the CDMA OMC provides the upper-level
network management center with a standard CORBA interface that makes it easy
for the user to develop an integrated network management system at a higher level.
The CORBA interface supports various management functions including alarm,
performance and configuration. With these complete and powerful functions, an
universal interface for multiple services can be achieved.
Also, the CDMA OMC provides other kinds of northbound interfaces to meet users’
requirements for diversified and professional NMC interconnection. Through the
SNMP northbound interface, alarm information can be reported to the upper-level
NMC, which is applicable for fast interconnection to most of high-level NMCs. The
FTP interface is also used to interconnect other NMCs.

5 Functions and Services
The NetNumen™ M3 (CDMA OMC) has numerous O&M functions to fully satisfy users’
actual management demands. It provides not only maintenance functions in compliance
with TMN specifications such as configuration management, fault management, security
management and performance management, but also other functions such as topology
management, system management, log management, operation tools and CDMA
analysis system, etc. The rich O&M functions help the operation and maintenance
personnel accurately know running state of network equipment, make it easy for them to
adjust and monitor the equipment, and keep the equipment running in optimal condition.
 Fault Management: The fault management helps the operation and maintenance
personnel know in time all abnormal running conditions in the CDMA network and
helps them to locate causes and positions, so that the user can find, handle and
solve the system faults as soon as possible and ensure normal running of the
network. Alarm correlation analysis helps eliminate redundant alarm information and
alarm storm, locate and eliminate fault causes.
 Performance Management: The performance management is responsible for
monitoring and analyzing performance of the network and NEs. With various
performance data collected from the NEs, the OMC knows network running
conditions, provides the operation and maintenance personnel with detailed
information that can offer guidance to the planning and adjustment of the network
engineering and improve the network quality.
 Configuration Management: The configuration management presents configurations
for all kinds of equipment resources and settings of important parameters in the
CDMA network, so that the user can know easily the configuration and usage of the
key network resources, make related statistics, improve management, and maximize
profits. Additionally, it also provides necessary reference data for performance
management and fault management.
 Security Management: The security management can protect and prevent
unauthorized OMC users from accessing or destructing the OMC and its NE system,
and legal users from ultra vires action. It records all security operation information for
review and ensures legal use of the system.
 Topology Management: The topology management provides a topology view for the
whole network. It provides key information management, including the geographic
location, alarm, and KPI.
 Log Management: The log management completes management of all kinds of
system logs that records information about all events and operations in the system.
With the logs, the user can know whether the system runs normally or not, locate the
cause of the fault, and trace back and review important events.
 OMC System Management: The system management is used to manage the CDMA
OMC itself. Through the system management, the user can better maintain the
CDMA OMC. In addition to monitoring the performance of the application server and
database server, the user can also provide common database management such as
database query, backup and recovery via the DBMS of the network management
system.

 Report Management: With related reports, the user can know running state of the
system in a fast, intuitive and convenient manner, and evaluate the system
performance. When combined with the policy management, the report management
system provides timed report function, i.e., timed printing of the reports. The time for
printing and the report type can be set. The user can preview and print the reports,
and store them in EXECL, TEXT, HTML, or PDF files.
 Tools Set: Through the man-machine interaction, the user can observe the NE
resources at the foreground. In order to manage dynamic resources and parameters
of the system, the user can make an in-depth analysis and adjust dynamically the
setting of NE parameters by means of various system tools such as signaling trace,
service observation and diagnosis. These tools provide technical means necessary
for system debugging, operation and management.
 Northbound Interface: The northbound interface function provides standard CORBA
interface that acts as an agent responsible for access to the third-party NMS. The
OMC also provides standard SNMP, and FTP interfaces for simple and easy
management and interconnection.
 Call Detail Tracing (CDT): The function of CDT can record the detail data created in
the process of mobile station calling, including the process of setting up, the calling
release and the hand off. It also supports the functions of data browse and analysis
in order to fast find out the problems of the calling. The development interface and
re-analysis function are provided by the software packet of the network optimization.
 CDMA Network Optimization (CNO2): The integrated network optimatization system
can present in a centralized manner all information related to important indicators,
serious alarms and configurations of the whole network, so that the maintenance
personnel can be clear about operation conditions of the whole network. By using
various evaluation methods and mathematic models, it can analyze network running
quality, operation support, and network construction. It provides expert knowledge
base that can automatically locate certain network problems, analyze their causes,
and offer reference solutions. Moreover, it provides powerful functions such as pilot
planning and optimization, adjacent cell planning and optimization, integrated report,
association analysis, etc.

Different NEs require different management overheads. The concept of logic
element (LE) is adopted in measuring management capability so as not to be confused
with the NE. The relation between the NE and the LE is shown in the table below.
Table 2 Conversion of NE and LE
NE Number of LEs
BSS (BSC+BTS) Count the number of LEs at the radio side
according to the number of carrier-sectors.
120 cells (carrier-sectors) = 1 LE, where, 1 BSC
(not including BTSs) = 120 cells
Theoretically, the CDMA OMC itself set no limit to the maximum number of NEs
to be controlled, but the restriction comes from the processing capability, data
throughput, and network bandwidth allowed for the CDMA OMC server. The server with
higher processing capability can be adopted to manage more NEs.
6.2 The Number of Concurrent Clients
For servers operating in various modes, the maximum number of concurrent clients
(including remote clients) supported by the system is listed in Table 3.
Table 3 The Maximum Number of Concurrent Clients
Server Configuration The Number of Concurrent Clients
Mode 1 40
Mode 2 80
Mode 3 120
Mode 4 200
6.3 Network Management Bandwidth
 Between the client and the server (GUI mode): Average bandwidth < 256 Kbits/s
 Between the NE and the OMM: As the NE and the OMM are usually located in the
same LAN, the 10Base-T Ethernet bandwidth is great enough to meet the
requirement.
 Between the OMM and the NMC: The average OMM data bandwidth for
management of a single BSS NE is less than 256 Kbits/s,. When several OMM
transfer data to the NMC, the bandwidth required is calculated by 200Kbits/s ×
the number of OMM. If necessary, the bandwidth redundancy shall be
considered.
