2 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 andcertificate management.

Transmission encryption can be performed between the M2000 client and server, between theM2000 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 ondigital certificates is performed for involved parties. The M2000 provides the digitalcertificate management function. M2000 can centrally manage certificates on the entire

network based on Certificate Management Protocol (CMP) V2. Currently, this functionapplies to the M2000, eNodeB.

Benefits

This feature brings about the following benefits:

This feature guarantees the confidentiality of data transmitted through TCP andeffectively 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.


6/26





4

Users can centrally manage the digital certificates of devices and the M2000, includingapplying for certificates, activating certificates, and updating the certificate revocation

lists (CRLs).

DescriptionTransmission encryption:

Generally, Transmission Control Protocol (TCP) is used for communications between theM2000 client and server, between the M2000 server and NEs. After SSL-based encryptedtransmission 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 unidirectionaland 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 FTPSand SFTP.

Security levels of network entities are determined by their roles and positions in thecommunications 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 allowsusers 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 alsomanually change the status of these SSL connections, if necessary.

This feature will decrease the M2000's management capability because complex SSLencryption 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, theM2000 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 theM2000, 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.

Managing certificates

The M2000 supports PEM and DER certificate formats defined in the ITU-T X.509v3standard. 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. Thiscertificate 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 theM2000 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 signedcertificate to the M2000 and deliver it to devices.

The M2000 allows users to view, activate, delete, and test device certificates and importthem 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, usersconfigure 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 modeof 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 forSSL-based data communication between NEs is on the CRL, the communication fails.

Enhancement

The following function is added to M2000 V200R012C00:

The M2000 supports the SSL protocol version TLS 1.2.

The M2000 generates an alarm when a device certificate fails to be loaded, has expired,

voltage, intelligent carrier shutdown, intelligent RF channel shutdown, low-energyconsumption mode, and scheduled eNodeB power-on and power-off.

− 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, userscan perform related settings so that some carriers are shut down when the carriertraffic 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 shutsdown 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-energyconsumption 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 scenariossuch 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 timesegment.

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 objecttype 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 energyconsumption and throughput in tables and charts. Comparison results can be saved asan XLS file or a PNG, JPG, or GIF image. This helps users evaluate eNodeB

energy-saving effects.

and ensures that the time of the entire network is consistent.

Benefits

The M2000 ensures that the time of all the network devices is consistent, enhancing operationand 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 servesas 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 suchas networking, SYN Clock V5 can serve as the middle-layer NTP server. SYN Clock V5obtains 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 satellitesystem provided by Russia. The navigation satellites use atomic clocks to provide the most accurateCoordinated Universal Time (UTC).

The iSStar provides the following functions:

HSL-integrated development environmentThe interface of the HSL-integrated development environment consists of the script

editing pane, debugging pane, running pane, and the feedback pane.

The script editing pane provides the basic text editing functions such as copying, pasting,cutting, searching, replacing, undoing, and redoing. The script editing pane also provides

the syntax check function.

The debugging pane provides powerful functions for debugging scripts. For example,

users can run the script step by step or in skip mode, set or cancel breakpoints, and perform or ignore sub-processes. In addition, users can view the stacks and variables of

the memory in the feedback pane.

The running pane provides a running environment for scripts. The supported execution

modes are partial execution, complete execution, execution for a single NE, andexecution for multiple NEs. Users can pause, resume, and forcibly stop a running script.

The running status of a script such as the output information, the MML messagesreturned from NEs, and the execution result 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 meets the requirements of program development engineers.

The iSStar provides the auto-indent function to increase the efficiency of editing scripts.

The iSStar provides a scalable HSL foundation class (HFC). It encapsulates complicated

and common service implementation such as file operation and MML text resolution to

functions. These service functions can be flexibly expanded, meeting variousrequirements. The HFC function library provides input association, through which thesystem searches for the associated functions that map the starting letters of user input.The associated results are displayed in a list on the GUI for users' selection.

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 thetarget scripts.

Script task scheduling

Scripts are executed through tasks. The iSStar supports scheduled tasks, periodic tasks,and immediate tasks. When creating a task, users can set the start time, period, executiontimes, associated NEs, main script, and accessory script of the task.

Script execution tasks are managed and scheduled by the centralized task module.Through the task manager, users can view the task information such as name, status, type,

period, start/end time, whether the last execution is successful, and execution times.Users can also start, pause, and stop the task.

Users can download the execution result report of a task. The execution result of a taskcan 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 in the form of transaction

messages and MML messages. Report output is the function provided by the HSL.

Report results are saved as XLS or HTML files. The result reports of a periodic task can be stored for seven days.

HSL

The HSL is the script language that is based on python. It seamlessly integrates with the

MML. The HSL provides variable numeric types, operators, condition check, loop, and

built-in functions. The HSL provides various library functions and allows users tocustomize functions.

The script language mechanism is as follows:

− Numeric types include integer, floating point, character string, Boolean, list,

dictionary, and file object.− Operators include basic operators, bit operators, comparison operators, Boolean

operators, sequence operators, and dictionary operators.

− Statements support simple statement and compound statement such as assignment

statement, simple expression, compound expression, condition check, loop, and

custom functions.

The HSL supports the following library functions:

− NE operation functions

− MML message parsing functions

− CSV parsing functions

− XML parsing functions

− Alarm message parsing functions

− Database operation functions

− Alarm operation functions

− EMS operation functions

− Type switchover functions

− Time functions

− Information input/output functions

− Network operation functions

−

Report operation functions− Directory and file operation functions

− GUI exchange database functions

− Task management functions

− Assert functions

− Mail sending functions

Application project management

The iSStar allows users to organize and manage scripts by taking an application projectas a unit, supporting the development of multiple scripts. Application projects are theadvanced organization of programs. Compared with files, application projects feature

high independence, integrity, and consistency. The iSStar allows users to compileapplication projects. It provides an interface for users to operate the configuration

parameters related to application projects, helping users design and use application projects.

The iSStar provides the following functions related to project management:

− Opening or creating a project

− Adding or creating a file in a project

− Closing a project

− Deleting a project

− Running a project

−

Compressing a project
