Optional Features (WOFD-900000)
2.1 Security Management
WOFD-210100 Encrypted Transmission
Availability
This feature was introduced in M2000 V200R005.
Summary
The M2000 uses encryption algorithms such as Secure Sockets Layer (SSL), FTP over SSL
(FTPS), and SSH FTP (SFTP) to ensure communication security between the M2000 and
network entities. Encrypted transmission for the M2000 involves transmission encryption and
certificate management.
Transmission encryption can be performed between the M2000 client and server, between the
M2000 server and NEs. Control channels and data transmission channels based on SSL, FTPS,
SFTP, or Hypertext Transfer Protocol Secure (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 parties. The M2000 provides the digital
certificate management function. M2000 can centrally manage certificates on the entire
network based on Certificate Management Protocol (CMP) V2. Currently, this function
applies to the M2000, eNodeB.
Benefits
This feature brings about the following benefits:

This feature guarantees the confidentiality of data transmitted through TCP and
effectively protects the privacy of user data.

The certificate authentication mode prevents untrustworthy connections. This ensures the
validity of SSL connections and further enhances transmission security.

Users can easily manage the digital certificates of the M2000 and devices, for example,
they can sign or revoke a certificate.

iManager M2000 V200R012
Optional Feature Description

Users can centrally manage the digital certificates of devices and the M2000, including
applying for certificates, activating certificates, and updating the certificate revocation
lists (CRLs).
Description
Transmission encryption:
Generally, Transmission Control Protocol (TCP) is used for communications between the
M2000 client and server, between the M2000 server and NEs. After SSL-based encrypted
transmission is used, an SSL-based encrypted data transmission channel, rather than a normal
TCP connection, is established between communication parties. Supported SSL protocol
versions are SSL 3.0, TLS 1.0, and TLS 1.2. This feature uses certificates for unidirectional
and bidirectional authentication between the M2000 and NEs. This ensures access validity.
In many scenarios, data is transmitted in files between network entities. For example:

The M2000 obtains performance, log, and configuration files from NEs.

The M2000 delivers performance and configuration files to third-party systems.

NEs download version and patch files from the M2000.
FTP uses plain text 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 M2000 provides different encrypted data transmission solutions in the following
scenarios:

Between the M2000 client and server: SSL, SFTP, and HTTPS

Between the M2000 server and NEs: SSL and FTPS
The M2000 supports both encrypted and unencrypted transmission modes. This feature allows
users to select data transmission solutions for the M2000 and NEs. Users can check in real
time whether the links between NEs and the M2000 use SSL connections. Users can also
manually change the status of these SSL connections, if necessary.
This feature will decrease the M2000's management capability because complex SSL
encryption algorithms occupy a large number of system resources and affect data transmission
efficiency.
Digital certificate management:

Supporting CMP V2
To comply with 3GPP specifications, the M2000 supports CMP V2. Using CMP V2, the
M2000 can establish an HTTP/HTTPS-based channel for managing digital certificates
with a Certificate Authority (CA). If NEs cannot directly communicate with the CA, the
M2000 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
M2000, including IP address, uniform resource locator (URL), protocol, and port. Based
on the information, the M2000 sets up a connection with the CA to apply for or update
device certificates.

Optional Feature Description

Managing certificates
The M2000 supports PEM and DER certificate formats defined in the ITU-T X.509v3
standard. The M2000 can manage device certificates, trusted 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 M2000 provides one-stop automatic
services for applying for device certificates, including creating an application form,
applying for device certificates, and delivering the certificates to devices.
If the M2000 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
M2000 and the M2000 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 M2000 and deliver it to devices.
The M2000 allows users to view, activate, delete, and test device certificates and import
them in batches. The M2000 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 trusted certificate can be a CA certificate or a certificate chain and it is used for
authenticating the validity of the peer certificate. The M2000 allows users to view,
import, and delete trusted certificates.
A CRL is a list for the CA to record revoked digital certificates. On the M2000, 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 M2000 then delivers these parameters to NEs and NEs obtain the CRL
based on the user configuration. If NEs cannot obtain a CRL from the CA, users can
manually import the CRL to NEs on the M2000. If a digital certificate used for
SSL-based data communication between NEs is on the CRL, the communication fails.

analysis, threshold alarms, and threshold messages, providing a shortcut for routine network
maintenance and problem localization.
Description
This feature implements the 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 M2000 allows users to quickly search
for objects by entering keywords. By default, the M2000 monitors the common KPIs. By
default, the M2000 monitors commonly used KPIs.
The M2000 provides default monitoring tasks and default KPIs. Users do not need to select
KPIs or objects for default monitoring tasks.
The M2000 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.
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 whose period is configurable 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 system 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.
The counters that can be monitored in real time are not the raw performance counters, but the
KPIs calculated based on the raw performance counters. The results of the counters that are
monitored in real time can be displayed in a list, line chart or column chart. The M2000
supports the following functions for displaying monitoring results:

The system allows users to set the 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 the upper and lower thresholds, which are set by being compared with
historical values. Users can set the time range for the preset threshold to take effect.

The M2000 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 system 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 the filter criteria of counter results so that the
system displays or hides only the data that meets the filter criteria.

When the system 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 the lower threshold. Users can also set the property, background,
tick table, and curve color of monitoring charts. 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 the line
chart, the interval of the horizontal axis changes accordingly.

−
Dynamic adjustment of PA voltage: 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 situations.
−
Intelligent carrier shutdown: This feature 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, 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 case of light
traffic.
−
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 cell TX power and available service
bandwidth of cells to prolong the system service duration.
−
Scheduled eNodeB power-on and power-off: This feature applies to special scenarios
such as the high-speed railway coverage scenario. If the traffic load within a time
segment is 0, the M2000 automatically powers off the eNodeB during the time
segment.
Checking power-saving status of the eNodeB
Users can check the current power-saving policy of the 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 according to the actual requirements.

Querying and measuring energy consumption and traffic load of eNodeBs
The M2000 allows users to query, measure, and compare energy consumption and traffic
load of eNodeBs. This facilitates evaluating energy-saving effects.
−
Querying energy consumption and traffic load
When querying eNodeB energy consumption and traffic, users can specify an object
type to query the traffic data aggregated hourly. The M2000 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 M2000 compares energy consumption and throughput of eNodeBs in different
periods. Then, the M2000 displays historical trends and changes of energy
consumption and throughput 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.

WOFD-192400 E2E Subscriber Tracing (eCNS)
Availability
This feature was introduced in M2000 V200R013C01.
Summary
Subscriber tracing refers to the process of tracing the signaling messages of the calls of a
specified UE, for example, a VIP UE in a certain time segment. By collecting and analyzing
statistics of the call signaling messages, users can locate call faults.
The LTE/EPC end-to-end subscriber tracing supports starting tracing tasks for a specified UE
number to collect the call messages of the UE on the eNodeB, USN, and UGW. In this way,
the end-to-end UE messages can be traced.
Benefits
The end-to-end tracing function allows O&M personnel to trace the messages of all calls on
the related NEs by creating a task. This helps O&M personnel troubleshoot call faults and
solve problems over networks.
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, the
NEs trace call messages of specified UEs and report the call messages to the M2000. The
M2000 parses the signaling messages and stores the parsing results in the database.

Benefits
The M2000 ensures that the time of all the network devices is consistent, enhancing operation
and data reliability.
The standard time reference source provided by the M2000 is both time and cost efficient.
Description
The system directly obtains the standard time from the GPS or the GLONASS by using the
dedicated time source server. Then, on the basis of the NTP/SNTP, the solution provides the
M2000 server and managed NEs with the time synchronization information.
SYN CLOCK V5 BITS, which is developed independently by Huawei, is used as the time
source server. It provides two NTP service channels for mutual backup. SYN Clock V5 serves
as the top-level time server node of the NTP time server. It provides the standard time source
for the M2000 server and the NEs that support the NTP/SNTP.
If the telecom operator already provides the NTP server at the highest layer, but cannot
provide the NTP service for all the nodes on the mobile O&M network owing to reasons such
as networking, SYN Clock V5 can serve as the middle-layer NTP server. SYN Clock V5
obtains time from the upper-layer NTP server and provides the time synchronization service
for the M2000 server and the managed NEs.
GPS is a Global Positioning System provided by USA, and GLONASS is a global navigation satellite
system provided by Russia. The navigation satellites use atomic clocks to provide the most accurate
Coordinated Universal Time (UTC).
