2 Optional Features (WOFD-900000)
2.1 Security Management
WOFD-210100 Encrypted TransmissionAvailability
This feature was introduced in V200R005.
Summary
The U2000 uses encryption protocols such as Secure Sockets Layer (SSL), FTP over SSL
(FTPS), and Secure File Transfer Protocol(SFTP) to ensure communication security between
the U2000 and network entities. Encrypted transmission for the U2000 involves transmission
encryption and certificate management.
Transmission encryption can be performed between the U2000 client and server and between
the U2000 server and NEs. Control channels and data transmission channels based on SSL,
FTPS, SFTP, or Hypertext Transfer ProtocolSecure (HTTPS) are established before network
entities communicate with each other. This ensures transmission security.
To ensure data integrity and non-repudiation during communications, authentication based on
digital certificates is performed for involved network entities. The U2000 provides the digital
certificate management function based on Certificate Management Protocol(CMP) V2.
Currently, this function applies to the U2000 and eNodeBs.
Benefits
This feature brings about the following benefits:
 This feature guarantees the confidentiality of data transmitted through Transmission
Control Protocol (TCP) and effectively protects privacy of user data.
 Certificate authentication prevents untrustworthy connections. This ensures validity of
SSL connections and further enhances transmission security.
 Users can centrally manage the digital certificates of devices and the U2000, including
applying for certificates, activating certificates, and updating certificate revocation lists
(CRLs).
Description
Transmission encryption:

iManager U2000
3
TCP is used for communications between the U2000 client and server and between the U2000
server and NEs. After SSL-based encrypted transmission is used, an SSL-based encrypted
data transmission channel, instead of a common TCP connection, is established between
communication parties. Supported SSL protocolversions are SSL 3.0, TLS 1.0, and TLS 1.2.
This feature uses certificates for unidirectional and bidirectional authentication between the
U2000 and NEs. This ensures access validity.
In many scenarios, data is transmitted in files between network entities. For example:
 The U2000 obtains performance, log, and configuration files from NEs.
 The U2000 delivers performance and configuration files to third-party systems.
 NEs download version and patch files from the U2000.
FTP uses plaintext for data transmission in bearer networks, where files are exposed to
interception. To address this problem, this feature provides secure file transfer based on FTPS
and SFTP.
Security levels of network entities are determined by their roles and positions in the
communications network.
The U2000 provides different encrypted data transmission solutions in the following
scenarios:
 Between the U2000 client and server: SSL, SFTP, and HTTPS
 Between the U2000 server and NEs: SSL and FTPS
The U2000 supports both encrypted and unencrypted transmission modes. This feature allows
users to select data transmission solutions for the U2000 and NEs. Users can check in real
time whether the links between NEs and the U2000 use SSL connections. Users can also
manually change the status of these SSL connections, if necessary.
This feature will decrease the U2000's management capability because complex SSL
encryption algorithms occupy a large number of U2000 resources and affect data transmission
efficiency.
Digital certificate management:
 Supporting CMP V2
To comply with 3GPP specifications, the U2000 supports HTTP/HTTPS-based CMP V2.
Using CMP V2, the U2000 can establish a channel for managing digital certificates with
a Certificate Authority (CA). If NEs cannot directly communicate with the CA, the
U2000 can provide agent services for NEs. Agent services allow users to apply for and
update certificates.
 Managing CA information
A CA is an entity that issues digital certificates. Users can set CA information on the
U2000, including the IP address, uniform resource locator (URL), protocol, and port.
Based on the information, the U2000 establishes a connection with the CA to apply for
or update device certificates.
 Managing certificates
The U2000 supports PEM and DER certificate formats defined in the ITU-T X.509v3
standard. The U2000 can manage device certificates, trust certificates, and CRLs, and
provides differentiated management functions for these certificates.
A device certificate is a file containing public keys and ownership information. This
certificate is digitally signed and issued by the CA and is used for authenticating parities
involved in communications. When communicating properly with the CA, the U2000
provides one-stop automatic services for applying for device certificates, including

iManager U2000
4
creating an application form, applying for device certificates, and delivering the
certificates to devices. If the U2000 cannot communicate with the CA, users can
manually apply for a device certificate. The procedure is as follows: Users fill in a
certificate application form on the U2000 and the U2000 accordingly generates an
application file; users submit the application file to the CA and the CA signs the
certificate; users then import the signed certificate to the U2000 and deliver it to devices.
The U2000 allows users to view device certificates and import them in batches, and
activate, delete, and test the device certificates. The U2000 reports an alarm when a
device certificate is about to expire, fails to be loaded, has expired, or becomes invalid.
This prevents service interruption due to exceptions that occur on the certificate.
A trust certificate can be a CA certificate or a certificate chain and it is used for
authenticating validity of the peer certificate. The U2000 allows users to view, add,
delete, and export trust certificates.
A CRL is a list for the CA to record revoked digital certificates. On the U2000, users
configure parameters for NEs to automatically obtain a CRL. The parameters include the
IP address, access port, and user name of the CA, and the save path and execution mode
of the CRL. The U2000 then delivers these parameters to NEs and NEs obtain the CRL
based on the user configurations. If NEs cannot obtain a CRL from the CA, users can
manually import the CRL to NEs on the U2000. If a digital certificate used for
SSL-based data communication between NEs is on the CRL, the communication fails.
Enhancement
The following functions are added to V200R012C00:
 The U2000 supports the SSL protocolversion TLS 1.2.
 The U2000 generates an alarm when a device certificate fails to be loaded, has expired,
or becomes invalid.

information about the live network devices, such as NE versions and hardware service
expiry dates. The information acts as a reference for allocating and changing resources.
 It provides accurate reference data in scenarios such as troubleshooting, U2000 upgrade,
and capacity expansion.
Description
The U2000 allows users to browse, query, maintain, synchronize, import, and export
inventory data.
 Browsing inventory data
Inventory data is categorized into logical inventory data and physical inventory data.
Logical inventory data includes information about cells and NE versions.
Physical inventory data includes information about racks, subracks, slots, boards,
antennas, and ports. Physicalinventory properties include the device locating
information, device name, device type, device version, electronic label, serial number
(SN), device manufacturer, and delivery date.
Inventory data varies according to NEs.
This feature allows users to query inventory data on the live network. The hierarchy
between objects in the inventory data is displayed in a navigation tree, and object
properties are displayed on a list. In addition, users can set criteria to filter and search for
inventory data. Query results can be displayed on a list and saved in a TXT, XML, or
CSV file.
This feature allows users to query electrical labels of base station boards even when the
boards are offline.
 Synchronizing inventory data
The U2000 provides the function of synchronizing inventory data so that the inventory
information on NEs is synchronized with that stored on the U2000 database. The U2000
supports manual and automatic synchronization. Synchronization operations are
performed as a task. Manual synchronization is performed by users based on site
requirements. The U2000 performs automatic synchronization based on preset
parameters and centrally manages automatic synchronization tasks by using the feature
WOFD-071200 Centralized Task Manager.

iManager U2000
6
Users can set synchronization task parameters such as the task start time, execution
period, and NEs. Users can also view the execution progress and status of the task.
 Automatic notification of inventory data changes
After the inventory data of an NE is changed, the NE automatically notifies the U2000 of
the change. This ensures that the inventory data on the U2000 is consistent with that on
the NE. Currently, only eNodeBs support this function.
 Exporting inventory data
The U2000 allows users to export the inventory data of a single NE or managed object
(MO) or NEs in batches.
Users can export the inventory data about NEs or MOs to the U2000 client. Inventory
data about a single NE, multiple NEs, or multiple MOs can be exported as a TXT, XML,
or CSV file, while inventory data about a single MO can be exported as an XML or CSV
file.
 Importing information about purchased parts
The information about purchased parts of one or more NEs can be collected by importing
files. Users can import inventory information about one or more NEs by importing files
in XML format, and inventory information about MOCs by importing files in CSV or
XML format. The objects that support this function are subracks, cabinets, boards, slots,
ports, antennas, and software.
 Maintaining inventory data
Users can change certain inventory data such as the user ID and end of service (EOS)
date. The results are saved in the U2000 database.

Summary
Centralized antenna line device (ALD) management provides GUIs that are based on the
browser/server (B/S) architecture. On the GUIs, users can perform centralized operation and
maintenance on eNodeB ALDs.
Benefits
 Telecom operators can remotely and centrally maintain ALDs, without operating ALDs
on the NE side. This reduces telecom operators' operating expense (OPEX).
 User-friendly GUIs are provided, which simplifies operations. This helps users focus on
important maintenance work and significantly improves maintenance efficiency.
 This feature allows users to add, adjust, and upgrade ALDs in batches. This requires less
maintenance workforce and reduces manualerrors.
 The B/S structure allows users to manageALDs through a web browser without
installing the client software.
Description
The U2000 displays the NE topology view of the antenna management system based on the
hierarchical structure of NEs. Before managing ALDs, users can select multiple eNodeBs
from the NE topology view and perform batch operations onALDs, such as power supply
management, configuration management, software management, and log management. This
improves maintenance efficiency.
The antenna management system provides the following functions:
 ALD power supply management
Users can query the states of ALD power supply switches and the alarm thresholds of the
current. Users can also set the states of ALD power supply switches and the alarm
thresholds of the current in batches on GUIs, or set the information in a file and import
the file to the U2000 to achieve batch settings.
Users can customize the types of non-standardALD power supply systems.
 ALD configuration management
Users can manage ALDs and ALD parameters, such as querying, scanning, adding,
modifying, and deleting ALDs and ALD parameters.
The ALDs that can be managed include remote electrical tilts (RETs) and smart
tower-mounted amplifiers (STMAs). RETs and STMAs provide the following
configuration management functions:
− RET: querying parameter information, calibrating tilt angles, setting tilt angles,
resetting RETs, and downloading configuration data.
− STMA: querying parameter information, and setting gains and working modes.
RETs and STMAs support auto-deployment tasks. After users start an auto-deployment
task, the U2000 automatically configures RETs and STMAs, turns on power switches,
and configures default parameters. This simplifies user configurations.
Users can add ALDs or reconfigure parameters of RETs and STMAs in batches in an
XLS or XML file and then import the file into the U2000.
In addition, the U2000 allows users to export the configuration data of ALDs to an XML
or XLS file. The exported configuration data includes the supplier code, SN, and

iManager U2000

software and hardware version information. The configuration data helps users collect
inventory data about ALDs on the live network.
 ALD software management
Users can check the current software versions of ALDs and upgrade ALD software in
batches.
 ALD log management
Users can manage NE operation logs for ALDs. NE operation logs record the
ALD-related MML commands that have been executed on eNodeBs. Users can query,
sort, and search for these logs, and export them to an XLS or XML file.
 ALD alarm management
Users can view the details about alarms related toALDs managed by the U2000 and
acknowledge or clear the alarms.

2.3 Fault Management
WOFD-120100 Alarm Remote Notification
Availability
Summary
The U2000 automatically notifies related O&M personnel of the alarms that meet the preset
conditions using short message messages (SMSs) or emails.
Benefits
By sending information about major network faults to related maintenance personnel, this
feature allows the maintenance personnel to remotely monitor the running status of the
network in real time. As a result, telecommunications rooms can be left unattended.
Description
The U2000 sends alarm notifications using SMSs or emails. The U2000 allows users to set
alarm notification conditions such as alarm severities, types, names, and sources. It also
allows users to set different time for sending alarm notifications. For example, users can
select a specific time segment during a workday to send the notifications.

iManager U2000

For details about alarm sources in the alarm notification conditions, see the feature WOFD-010300
Alarm Viewer.
If the U2000 sends alarm notifications using SMSs, a short message gateway (SMG) or short
message modem of GSM or CDMA, or a WCDMA data card needs to be configured. When
configuring the short message modem, users can set the short message modem
communication parameters and specify mobile numbers on the related GUI. When
configuring the message gateway, users can set the parameters such as the host address, port
number, user name, password, and coding protocolon the related GUIs.
If the U2000 sends alarm notifications using emails, a mail server is required. Users can set
the mail server and the communication parameters of emails on the related GUIs.
The U2000 allows users to set the maximum size of information that can be received by a
mailbox or the maximum number of SMSs that can be received within a certain period to
prevent the errors that occur when large-size data is or many short messages are sent within a
certain period. The alarm data and the SMSs that exceed the thresholds are discarded. The
time unit can be minute or hour.

2.4 Network Monitoring and Analysis
WOFD-190100 Real-Time Performance Monitoring
Availability
Summary
This feature implements the collection, display, and analysis of key performance indicators
(KPIs) in quasi-real time. By using this function, users can view the analysis results in
multiple graphical modes.
To protect users' privacy, related information may be anonymized.
Benefits
 This feature provides multiple graphical display modes, enabling users to directly view
the dynamic changes of KPIs.
 This feature displays the running status of the network in time through correlation data
analysis, threshold alarms, and threshold messages, providing a shortcut for routine
network maintenance and problem localization.
Description
This feature implements real-time collection and analysis of KPIs in task mode. Users can
start a monitoring task, select an object to be monitored, and set parameters such as the object
class, monitoring type, and monitoring counters. The U2000 allows users to quickly search
for objects by entering keywords. By default, the U2000 monitors the common KPIs.
The U2000 provides default KPIs and monitoring tasks. Users do not need to select KPIs or
objects for default monitoring tasks.
The U2000 provides the function of monitoring object groups of an NE type. Object group
types are defined by default, whereas object group instances can be customized. Users can
create a monitoring task after selecting object group instances as monitored objects. In this
way, users can collect and analyze KPIs for a group of objects at a time.

iManager U2000
11
Real-time performance monitoring is classified into common-period monitoring and
short-period monitoring. Each type of NE supports only one monitoring period at a time.
Tasks of both monitoring types can monitor default KPIs.
 Common-period real-time performance monitoring supports the following functions:
The periods of real-time performance monitoring supported by NEs are the same as the
periods described in the feature WOFD-030100 Performance Measurement Data
Collection and Storage. The U2000 sets the default KPI monitoring periods for each type
of NE. Users can also modify the monitoring periods as required. The new monitoring
periods take effect when new monitoring tasks are started.
KPIs calculated based on raw performance counters can be monitored in real time but
raw performance counters cannot. The results of the counters that are monitored in real
time can be displayed in a list, line chart, or column chart. The U2000 supports the
following functions for displaying monitoring results:
− The U2000 allows users to set value thresholds of counters that can be monitored in
real time and set filter criteria. The settings are used to generate threshold alarms. The
thresholds to be set consist of upper and lower thresholds, which are set by being
compared with historical values. Users can set the time range for the preset thresholds
to take effect.
− The U2000 supports the integrity check of monitoring data. Users can set to use
curves in special colors to identify missing status or loss status.
− When the U2000 displays monitoring results in a list, users can adjust the display of
the monitoring list by setting counter thresholds. In the list, the counter values that
are greater than the upper threshold or less than the lower threshold are displayed
according to the preset formats. Users can also set filter criteria of counter results so
that the U2000 displays or hides only the data that meets the filter criteria.
− When the U2000 displays monitoring results in a line chart or column chart, users can
adjust the display of the monitoring charts by setting the counter thresholds, including
the upper threshold and lower threshold. Users can also set the property, background,
tick table, and curve color of a monitoring chart. They can also print a monitoring
chart or save it as a figure. When the data is displayed in a line chart, the horizontal
axis represents time and the vertical represents counter values. When users zoom in
on the line chart, the interval of the horizontal axis changes accordingly.
− The U2000 allows users to export the data from a monitoring chart or table to files.
The supported file formats are XLS, CSV, HTML, and TXT.
− The U2000 supports trend analysis of counters. The U2000 displays the counter trend
in a line chart according to the objects, counters, the difference between an upper
threshold and a historical value, and the difference between a lower threshold and a
historical value set by users. The curves of the upper thresholds, lower thresholds,
and actual values are displayed in different colors.
− The U2000 supports the function of displaying counter monitoring results in a
topology view. If users place the pointer on the topology icon of a measured NE after
the tool tip is set, the tip label of the counter monitoring results of the latest period is
automatically displayed.
Historical values refer to the performance counter values collected by sampling and calculating the
recent historical data.
 The period of short-period real-time monitoring is fixed, and each type of NE supports
only one short period.

2.5 Base Station Power Saving Management
WOFD-200200 Base Station Power-Saving Management – LTE FDD/TDD
Availability

iManager U2000
13
Summary
The U2000 provides the function of flexibly configuring power-saving policies of eNodeBs to
reduce the energy consumption of lightly loaded eNodeBs. Users can easily check the
power-saving status of eNodeBs and reconfigure power-saving parameters. The U2000 also
provides the functions of checking eNodeB energy consumption and collecting energy
consumption statistics.
Benefits
 Users can flexibly set eNodeB power-saving policies so that the U2000 enables the
power-saving feature for an eNodeB when the eNodeB traffic is low. This reduces
eNodeB energy consumption without affecting ongoing services, and reduces OPEX.
 Users can easily monitor the power-saving status of eNodeBs and reconfigure
power-saving parameters.
 Users can check eNodeB energy consumption and collect energy consumption statistics
to directly learn about network energy consumption.
Description
This feature provides the following functions:
 Configuring and managing power-saving policies
The U2000 provides the function of configuring the eNodeB power-saving feature to
implement flexible management of eNodeB power-saving policies. The policy properties
that can be set include the valid time segment, power-saving function switches,
shutdown decision thresholds, and restoration conditions. The U2000 provides the
following eNodeB power-saving features: dynamic adjustment of power amplifier (PA)
voltage, intelligent carrier shutdown, intelligent RF channel shutdown, low-energy
consumption mode, and scheduled eNodeB power-on and power-off.
− Dynamic adjustment of PAvoltage: Users can adjust the offset voltage of the PA
based on different output power and modulation modes to ensure that the PA
efficiently runs in power-saving mode in different conditions.
− Intelligent carrier shutdown:This function applies to the scenario where an area is
covered by multiple carriers. Based on the traffic distribution of each carrier, users
can perform related settings so that some carriers are shut down when the carrier
traffic is low. Then, the eNodeB enables UEs to migrate to some of the carriers and
shut down the carriers whose traffic is low.
− Intelligent RF channel shutdown:Based on the distribution of cell traffic volumes,
users can perform related settings so that the eNodeB retains only one RF TX channel
and shuts down other RF TX channels to reduce static energy consumption in light
traffic hours.
− Low-energy consumption mode: Users need to force a cell to switch to low-energy
consumption mode in case of exceptions such as power supply undervoltage. Then,
users can reduce specifications such as the cell TX power and available service
bandwidth of cells to prolong the U2000 service duration.
− Scheduled eNodeB power-on and power-off:This function applies to special
scenarios such as the high-speed railway coverage scenario. If the traffic volume
within a time segment is 0, the U2000 automatically powers off the eNodeB during
the time segment.

iManager U2000
14
 Checking power-saving status of eNodeBs
Users can check the current power-saving policy of a selected eNodeB, check whether a
certain power-saving feature is enabled, and check the detailed configuration parameters
of the feature. In addition, users can further reconfigure the detailed configuration
parameters based on site requirements.
 Querying and measuring energy consumption and traffic volumes of eNodeBs
The U2000 allows users to query, measure, and compare energy consumption and traffic
volumes of eNodeBs. This facilitates evaluating energy-saving effects.
− Querying energy consumption and traffic volumes
When querying eNodeB energy consumption and traffic volumes, users can specify
an object type to query the traffic data aggregated hourly. The U2000 displays query
results in tables and charts and allows users to export the results as an XLS file or a
PNG, JPG, or GIF image.
− Displaying network energy-saving effects
The U2000 compares energy consumption and traffic volumes of eNodeBs in
different periods. Then, the U2000 displays historical trends and changes of energy
consumption and traffic volumes in tables and charts. Comparison results can be
saved as an XLS file or a PNG, JPG, or GIF image. This helps users evaluate eNodeB
energy-saving effects.

This feature can be used to quickly locate and resolve problems. Normally there is no way to
avoid that some user data such as the international mobile subscriber identity (IMSI) and
mobile station international ISDN number (MSISDN) will be used during troubleshooting.
ISDN is short for integrated services digital network. However, this function provides an
anonymous data processing method. Users are obligated to take considerable measures in
compliance with the local laws to ensure that the personaldata of subscribers is fully
protected. The measures include turning on the anonymization switch on the U2000 and
deleting the folders where tracing records are saved after a problem is resolved.

iManager U2000
15
Summary
This feature is provided for eCNS, eCN equipment.
Subscriber tracing refers to the process of tracing the signaling messages of all the calls of a
specified UE, for example, a VIP UE within a certain time segment. By collecting and
analyzing statistics about the call signaling messages, users can locate callfaults.
End-to-end subscriber tracing supports starting tracing tasks for a specified UE number to
collect the call messages of the UE on eNodeBs and eCNS. In this way, the end-to-end UE
messages can be traced.
Benefits
This feature allows O&M personnel to create a task to trace messages of all calls for a
specified UE within a certain time segment on related NEs. This helps O&M personnel rectify
call faults and solve problems among NEs.
Description
The parameters involved in creating a subscriber tracing task are the task name, tracing
number (single option), tracing reference number, NE (multiple options), interface setting,
and start time and end time.
The duration of a subscriber tracing task is one day by default, and the maximum duration is
seven days. Users can specify the start time and end time. After a tracing task is started, NEs
trace call messages of specified UEs and report the call messages to the U2000. The U2000
parses the signaling messages and stores the parsing results in the database.
Enhancement
None
Dependencies
This feature applies to eLTE2.2 and later versions.
This feature works with the feature WOFD-191200 Centralized Subscriber Tracing – LTE

2.7 OSS Solution
WOFD-540100 Network Time Synchronization Solution
Availability
Summary
The U2000 provides a complete time synchronization solution for the mobile O&M network
and ensures that time on the entire network is consistent.

iManager U2000
16
Benefits
 The U2000 ensures that the time on all the network devices is consistent, thereby
enhancing operation and data reliability.
 The standard time source provided by the U2000 is both time and cost efficient.
Description
The U2000 directly obtains the standard time from the Global Positioning System (GPS) or
the Global Navigation Satellite System (GLONASS) by using a dedicated time source server.
Then, based on Network Time Protocol(NTP)/Simple Network Time Protocol(SNTP), the
solution provides the U2000 server and managed NEs with the time synchronization
information.
SYNCLOCK V5 BITS, which is developed independently by Huawei, is used as the time
source server. It provides two NTP service channels for mutual backup. SYNCLOCK V5
BITS serves as the top-level time server node of the NTP time server. It provides the standard
time source for the U2000 server and NEs that support NTP/SNTP.
If a telecom operator already provides the top-level NTP server, but cannot provide the NTP
service for all the nodes on the mobile O&M network owing to reasons such as networking,
SYNCLOCK V5 can serve as the intermediate NTP server. SYNCLOCK V5 obtains time
from the upper-layer NTP server and provides the time synchronization service for the U2000
server and managed NEs.
GPS is provided by USA, and GLONASS is provided by Russia. The navigation satellites use atomic
clocks to provide themost accurate Coordinated Universal Time(UTC).
Enhancement
The U2000 server functions as an intermediate NTP server.
Dependencies
This feature applies to NEs that support the feature WOFD-070800 Supporting Network Time
Synchronization.
To ensure that the final delivery meets expectations and requirements of customers, this
feature must be delivered with dedicated solution analysis, planning, and implementation
provided by Huawei. These services, however, are not contained in the software license of this
feature.

returned from NEs, and execution results are displayed in the feedback pane in real time.
The iSStar retains the difference-based display of keywords, character strings, numerals,
names of invoked functions, comments, and matching brackets for easy browsing. The
display mode helps program development engineers easily browse scripts.
The iSStar provides the auto-indent function to improve script editing efficiency.
The iSStar provides a scalable high-level foundation classes (HFC). It encapsulates
complicated and common service implementation to functions. These service functions
can be flexibly expanded, meeting various requirements. The HFC function library
provides input association, through which the U2000 searches for the associated
functions that map the start letters of user input. The associated results are displayed in a
list on the GUI for users to select.
The iSStar supports the logical debugging through virtual NEs. Users can set virtual NEs
in the debugging environment so that they can perform basic logical debugging on target
scripts.
 Script task scheduling
Scripts are executed using tasks. The iSStar supports scheduled tasks, periodic tasks, and
immediate tasks. When creating a task, users can set the start time, period, number of
execution times, associated NEs, main script, and accessory script of the task.
The U2000 centrally manages script execution tasks by using the feature WOFD-071200
Centralized Task Manager. Using the task manager, users can view task information such
as the task name, status, type, period, start/end time, whether the last execution is
successful, and number of execution times. Users can also start, pause, and stop the task.
Users can download task execution result reports. The task execution results can be
displayed on the GUI or exported to a report. The results of periodic tasks cannot be
displayed on the GUI. The results are displayed on the GUI as interaction messages and
MML messages. Report results are saved as XLS or HTML files. The result reports of a
periodic task can be stored for seven days.

2.10 Pool Management
WOFD-231800 eCNS Redundancy
Availability
Summary
The U2000 provides centralized monitoring and maintenance on eCNSs in an eCNS
redundancy pool. The managed items include data configuration of the eCNS redundancy
pool, data consistency check, and performance monitoring of the redundancy pool. These
functions meet requirements for site deployment and routine operation and maintenance.
Benefits
This feature provides centralized management and monitoring functions. This allows users to
manage and maintain the redundancy pool network directly, conveniently, and quickly. This
reduces OPEX.
Description
This feature allows one eNodeB to belong to multiple eCNSs. The UEs to be connected are
distributed into appropriate eCNSs according to the capacity ratios of the eCNSs. Then, UEs
can share eCNS resources. If an eCNS is faulty in the eCNS redundancy pool, the eNodeB
identifies the fault and switches over the new UE services that are to be assigned to the faulty
eCNS to other properly working eCNSs in the pool. This implements redundancy between
eCNSs in the pool.
This feature implements centralized monitoring and maintenance of eCNS redundancy pools
and eCNSs in the pools.
 This feature allows users to create, delete, and modify an eCNS redundancy pool, browse
the pool information, and show the pool in a topology view.
 This feature allows users to centrally modify and deliver parameters related to eCNS
redundancy.
 Provides automatic and manual data consistency check for an eCNS redundancy pool:
− In automatic check mode, the U2000 periodically checks data (including subscriber
registration data) consistency of eCNSs in the eCNS redundancy pool and generates
check results. Based on the check results, the U2000 automatically generates a data
adjustment script. The script needs to be executed manually.
− In manual check mode, a user selects eCNSs and related data items to perform the
immediate data consistency check.
 Performs real-time load monitoring for a minimum of 30-second period. The U2000
monitors the number of subscribers served by each eCNS, number of activated
subscribers, and total number of subscribers, and displays the load changes in a column
or line chart.
 Supports real-time monitoring of eCNS loads in the eCNS redundancy pool, and
centrally displays the comparison information about all eCNS loads in a chart.

iManager U2000
22
 When load imbalance occurs on multiple eCNSs in the eCNS redundancy pool, the
U2000 migrates subscribers from heavily loaded eCNSs to lightly loaded eCNSs or from
an eCNS to be upgraded to other eCNSs. The load balancing function helps reduce
subscriber connections on heavily loaded or overloaded eCNSs, preventing overload
faults.
 In an eCNS redundancy pool, subscribers may be allocated to different eCNSs.
Subscriber locating can help search for subscribers in an eCNS redundancy pool to query
the server to which a specified subscriber belongs and related information. It can also
search for the eCNS to which a subscriber belongs by using the subscriber identifier. The
function of quickly locating subscribers reduces maintenance workload and improves
fault locating efficiency.
 The U2000 periodically checks the load of each eCNS. If the load difference between
eCNSs reaches the preset threshold, the U2000 generates an unbalance load alarm. Users
can set the check period and load difference threshold.
