1. Introduction to WebEM
WebEM overview, requirements and functionality

WebEM overview
Web Element Manager (WebEM) is a web-based application for maintaining and
commissioning a BTS. WebEM can be used both in an online (direct connection to the BTS)
and offline mode (saved WebEM application) for configuration creation, modification and
troubleshooting purposes.

English is the only language supported by WebEM. However there are some parameters that
can be inserted in local language:

MRBTS BTS name (btsName)

LNCEL Cell name (cellName)
CBSD User Identity (userId)
TNL/LOAMPRF/ETHIF/VLANIF/ETHLK/BFD/PKTFLTR/IKEP/IPSECP/SECPOL/IPIF/IP
RT/IPRTV6/FLOWCL/FSTSCH User label (userLabel)
IPSECTEMPLATE User label Prefix (userLabelPrefix)
SMOD/RMOD/ASIRMOD/SMOD_EXT Module Location (moduleLocation)
EAC_IN/EAC_OUT Description (descr)

Note:

For example, for numerical values of the parameters the decimal separator is a dot
and we don't use comma as a delimiter in numbers larger than 999.

Using WebEM doesn't interfere with the usage of other element managers although it's not
recommended to have more than one type of element manager connected to the site at
the same time.

WebEM is used starting with the LTE 19, SRAN 17A and 5G19A (for classical gNB) releases.

Note:

The screenshots are merely a representation and must be considered as examples of

the depicted content. The current release of SRAN software may differ from the
information in screenshots. To enlarge the figures in the document, open them in a
new tab.

Requirements
To connect to the BTS, type in the BTS management plane IP address (or LMP IP address in
case of a local connection), using one of the supported internet browsers:
Chrome (recommended)
Mozilla Firefox

Note:

When using Chrome you need to disable the Throttle Javascript timers in
the background flag. Otherwise, WebEM disconnects from BTS when a web browser
or WebEM tab is not active. This leads to interrupting ongoing operations.

Note:

Firefox can slow down or even crash due to the following events:

Leaving Firefox open with WebEM running for a few days

Performing resource-heavy operations such as repetitive software updates without
restarting Firefox or cleaning the cache

In case of Firefox malfunction, refer to the official Firefox support page:

https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-or-cpu-resour
ces or use Chrome instead.

WebEM can be launched from any PC that can run the Chrome or Firefox browser; however
for better performance, the following specification is required:
The minimum screen resolution: 1366x768 pixels (1920x1080 is recommended)
CPU: 2 GHz 32-bit (x86) or 64-bit (x64)
RAM: 4 GB

WebEM User Guide

Note:

Depending on the browser type or version, loading WebEM from the browser cache
may cause the application not to load successfully. In such a case, it is required to
either clear the browser cache or refresh the page disregarding the cache (Ctrl+F5).

Functionality
As long as WebEM remains launched and connected to the BTS, the updates are constantly
collected in predefined periods in WebEM.

Note:

Due to the defined period of data synchronization between WebEM and the BTS,
WebEM may not be able to display all of the BTS status information.

WebEM introduces a new type of file, the Info Model Snapshot file (IMS2). IMS includes a full
BTS runtime data for a certain period of time. IMS2 files can be saved manually from WebEM,
or they can be automatically retrieved by WebEM when a BTS snapshot is collected.

The save location of files downloaded from WebEM (for example SCF, IMS2, or snapshot
files) depends on the browser settings.

2. WebEM protection against HTTP flood attack

Prior to SRAN 21A/5G21A, the WebEM application had to be downloaded to a PC before
logging in. As a result, it was possible for unauthorized users to access BTS internal data
or perform an HTTP flood attack by initiating multiple WebEM downloads without
authentication. The CB005784: Protection of WebEM Against HTTP Flood Attack feature
improves security by separating the logging in functionality from the WebEM application.

The CB005784: Protection of WebEM Against HTTP Flood Attack feature introduces the
following changes to WebEM:
A full application is downloaded only after a successful logging in.
After successfully logging in, WebEM creates a new connection.
Logging in is done through an HTTPS-based interface.
An offline version of WebEM can only be downloaded after logging in.
WebEM sends a notification when a BTS receives more HTTP requests than the
predefined limit.
WebEM delivery to Support portal - only Admin.html is delivered.

3. WebEM user interface

The WebEM user interface can be divided into the following areas: Connection, BTS site
information, Top menu, User management, Options, Navigation Panel, Working Panel, and
Details Panel.

WebEM User Guide

Figure 12: WebEM Timeline tab

The Timeline tab lists updates received from the BTS site. After logging in to WebEM, the
IM Snapshot Collected message appears and WebEM downloads changes done on BTS.

This tab also allows you to select and display data for a specific time frame. Each timestamp
includes detailed information about the BTS state at that certain point in time. Timestamps
are displayed in the BTS timezone. As long as the connection between WebEM and BTS is
established, the Timeline list is updated with new entries, which can be saved to Info
Model Snapshot (IMS2) file at any time. In an offline mode, when the IMS2 file is loaded, the
list shows all available (saved) entries.

This functionality is useful for troubleshooting. For example, if a problem occurs on site at a
certain time and then disappears, you can choose the right timestamp and see what
happened at that particular time. You can also navigate through the timeline to see what
caused the problem to disappear.

It is possible to load a list of changes that occurred before the connection to the BTS. The
history load option appears after the first connection to the BTS, but only when the BTS is
synchronized. Clicking the Yes button starts the history load process.

the static hardware properties. If the validation is triggered in the online mode, then the
validation of static hardware properties is done against the detected hardware on the
site, mapped to the objects from the configuration plan. In case the validation is
triggered in the offline mode (without the IMS2 file loaded), then the validation of static
hardware properties is done against the planned product codes from the configuration
plan. When the IMS2 file is loaded to the offline WebEM, the validation is done against the
hardware from the IMS2 file, simulating the online mode.
Validate with Detected Hardware (available only in Hardware Errors view) -
retriggers the validation of the configuration plan against the parameter relationships
related to the detected hardware.
Activate Plan - opens a pop-up window where clicking the Execute button sends the
configuration to the BTS. To send the plan to the BTS, but not activate it, choose the

creating new configurations as well as editing the existing ones, including inactive
configurations, on the BTS or loaded from an SCF. It is also possible to use Commissioning
Wizard in an offline mode (with or without a previously loaded IMS2 file).

Note:

When all system modules, baseband modules, and radio modules as well as the
detected cables between them are commissioned, it is not possible to change the
existing CABLINKs or manually create a new one. In this case, the cables in the
configuration must fully correspond to the detected cables only.

Configuration can be performed via two channels: Commissioning Wizard site view and
Commissioning Wizard step-by-step view. The site view (topology view) enables you to
create basic modules and logical items (like cells) and establish connections between them.
The step-by-step view (configuration wizard) allows you to create the same configurations
as in the site view, but, additionally, more advanced parameters can be defined here.

To access the step-by-step view, go to Navigation Panel, Steps tab, and click on a

WebEM User Guide

Figure 35: Parameter Editor tab

You can use Parameter Editor to manage objects and parameters in a controlled way; it
allows you to set only the parameter values of a correct data type (for example, string or
number) and inside a correct range. Nevertheless, it doesn't enforce hardware-specific
limitations, so it allows you to set values not appropriate for a given hardware.

Parameters are used to configure and control the BTS site; they are grouped into managed
object (MO) classes:
Set by system parameters cannot be changed by the user.
Mandatory parameters are required for a BTS to work properly. When omitted, a message
about a missing or invalid parameter is displayed.
Optional parameters are used to further configure the system.

WebEM provides functionalities necessary to easily find and edit necessary parameters as
well as view parameter details.

Whenever parameter information is loaded from an SCF, validation is performed

automatically to detect configuration errors such as disallowed or conflicting parameter
values. Validation results are displayed in the Definition errors, Relation errors
and Hardware errors tabs. Validation can also be performed manually by using the
Validate Plan button.

To see parameters, an MO must be previously selected in Navigation

Panel ► Objects. After the selection, all assigned parameters are displayed along with
MO's name. Note that not all MOs have associated parameters. In such cases, only the MO's
name is displayed, along with a Parameters not available notification.

Filtering parameters can be done in real time, using either of the following methods:

Issue 15A. © 2022 Nokia. Nokia Confidential Information 57

Use subject to agreed restrictions on disclosure and use.

WebEM User Guide

The Search all text field - search by parameter name or abbreviated name through all the
existing parameters
The following filtering options, available only for visible parameters:
Filter in parameter status column, by mandatory and optional parameters, and also by
modified, invalid, existing, and non-existing parameters
Parameter name column text field
Abbreviation column text field

For example, selecting modified and invalid options parameters displays only parameters
that have been modified with incorrect values.

To add a parameter, enter Planned Value for the selected parameter. The new
parameter is added after activating a configuration plan.

Parameters are displayed in a table view in an alphabetical order. The first column shows
parameter status:
- Parameters that were modified; the new value is sent to the BTS after using the
Activate plan option.
- Parameters marked for deletion; the parameters are deleted after using the
Activate plan option.
- Parameter value is invalid.
- Parameter is mandatory.

If the runtime configuration is loaded, the actual values from the BTS are shown in the
Actual Value column.

The Actions column can be used to perform certain actions on a given parameter:
- Add an element or structure.
- Remove en element.
- Delete a parameter.
- Set the Planned Value to the Actual Value. If there is no Actual Value or the
SCF is used, this action deletes the value.
- Set the parameter to its default value.

Using the (details) button expands the Details panel, displaying detailed information on
the selected parameter, including validation errors (if any). The (hide) button closes the
pane.

Some BTS management operations, which can be performed by configuring certain NIDD
objects and for which WebEM doesn't provide any dedicated views or functionalities, can be

in Parameter Editor and then validating and activating the planned configuration plan.

5.1.3 Conflicting commissioning data

The description of WebEM behavior when conflicting commissioning data occurs

When you make changes in the Commissioning Wizard or Parameter Editor, it is

possible that commissioning data used by the BTS is modified in another WebEM session, in
NetAct, or internally by the system. Changes made by the user in Commissioning Wizard
or in the Parameter Editor may conflict with changes applied to the system.

WebEM's behavior depends on how conflict injection has been configured:

When a delta or full recommissioning is performed via another WebEM session or via
NetAct, it is impossible for WebEM to merge the changes implemented in the current
session with the changes applied to the system; therefore, it is only possible to save the
backup SCF with the applied changes.
When the changes are performed by the system (by configuring the SetByTheSystem
parameters), WebEM merges the changes provided by the system with the changes
performed by the user in a particular WebEM session. When the system modifies the
same object class as the user, WebEM notifies the user about the conflict. When that
happens, it is possible to either:
Switch to the Frozen mode
Refresh the changes (which causes the whole Parameter Editor to reload, and
restores SCF form before the conflict took place)
Save the backup SCF

In the Frozen mode, you can implement all the changes to the configuration before
conflicting changes in the system are applied. After sending the changes to the system in
the Frozen mode, a partial activation takes place, and the plan is activated on the BTS side.
It is not possible to switch from the Frozen mode to the Normal mode without losing all the
implemented configuration changes. It is not possible to enter the Frozen mode manually
(this mode can only be entered when WebEM notices conflicting changes).

5.1.4 Validation Errors (Definition, Relation, Hardware)

Validation Errors tabs are displayed after parameter validation has been performed
and provided some errors have been detected.

Access to Validation errors view: Top

Menu ► Configuration ► Commissioning wizard/ Parameter
Editor ► Definition Errors/ Relation Errors/ Hardware Errors

Validation is used to detect errors such as incorrect or missing parameter values, conflicting
parameter values, or parameter sets not matching configuration rules.

The same filtering and configuration options as in Parameter Editor are available in
there.

Whenever parameter information is loaded (either from the current configuration or the
SCF), validation is performed automatically in order to detect configuration errors such as
not allowed or conflicting parameter values. Validation results are displayed in the
Definition Errors, Relation Errors, and Hardware Errors tabs.

Relation and hardware errors can be categorized into errors and warnings, based on their
severity level. Warnings don't prevent provisioning a plan to a BTS. It's possible, although not
recommended, to activate a plan with relation or hardware errors. In such cases, Nokia does
not take responsibility for any plan activation failures.

Validation consists of:

XML validation - verifies file integrity and structure (in case of the SCF).
NIDD validation - detects incorrect parameter values or missing mandatory parameters.
Parameter relation error validation - detects conflicting parameter values.
Hardware validation - detects incorrect hardware-related parameter values, conflicting
with the planned or actual hardware used on the site.

60 © 2022 Nokia. Nokia Confidential Information Issue 15A

Use subject to agreed restrictions on disclosure and use.

WebEM User Guide

Validation errors, if any, are grouped into three categories and displayed separately:
Definition Errors groups errors such as unknown parameter or MO names, missing
mandatory parameters or mandatory values, incorrect values. When definition errors
occur, plan activation is not possible. Parameter values can be modified directly from this
view.
Relation Errors groups errors related to relationships between parameters or
parameter sets. For example, when a certain parameter value conflicts with another.
Hardware Errors groups errors related to the planned or actual hardware
configuration. For example, when hardware-related parameter values do not match the
hardware used on the site (such as the serial number, unit name, and so on).

Note:

WebEM gives the user tips on how to repair errors according to validation rules of
parameter description language (PDL).

It is possible, but not recommended, to activate a plan with relation or hardware errors.
Nokia does not take responsibility for a plan activation failure in case the plan is activated
with relation or hardware errors.

WebEM User Guide

Note:

If there are no errors, but the plan activation fails during the activation of delta
configuration, it can be caused by making simultaneous changes to related
parameters under the TNLSVC managed object. It can be solved by sending those
changes to the BTS in separate delta configuration plans. For example, the plan fails if:
1. In the current configuration, FLOWCL IP interface reference (ipIfDN) is set
to MRBTS-1/TNLSVC-1/TNL-1/IPNO-1/IPIF-1 and FSTSCH IP interface
reference (ipIfDN) isn't set.
2. In a delta configuration plan, FLOWCL IP interface reference (ipIfDN) is
changed to MRBTS-1/TNLSVC-1/TNL-1/IPNO-1/IPIF-2, and FSTSCH IP
interface reference (ipIfDN) is set to
MRBTS-1/TNLSVC-1/TNL-1/IPNO-1/IPIF-1.

To solve this issue, you can send the changes in two separate delta configuration
plans:

1. Change FLOWCL IP interface reference (ipIfDN) to

MRBTS-1/TNLSVC-1/TNL-1/IPNO-1/IPIF-2
2. Set FSTSCH IP interface reference (ipIfDN) to
MRBTS-1/TNLSVC-1/TNL-1/IPNO-1/IPIF-1

WebEM User Guide

The Certificate Management functionality offers a common way to manage certificates

and their functions. Certificates are used to ensure that a public key comes from a trusted
authority. A certificate provides information about the owner of the certificate, owner's
name, certificate usage, duration of validity, resource location, or distinguished name, which
includes the common name, and the certificate ID of the person who certifies (signs) this
information. It also includes the public key, and finally a hash to ensure that the certificate
has not been tampered with. To see detailed info about each certificate, click on the
appropriate row in a certificate table. All information is displayed in the Details panel.

The Certificate Authority (CA) maintains a list of all signed certificates as well as a list of
revoked certificates (CRL). A certificate is unsafe until it is signed, as only a signed certificate
cannot be modified. A certificate management protocol (CMP) server must be configured to
manage certificates automatically.

When a BTS certificate is changed, the browser may fail to validate the SSL certificate. In
that case, WebEM cannot set up a new HTTPs connection, which may result in, for example, a
file transmission failure. Refresh the web page and manually accept the certificate to solve
this issue.

5.3.1 BTS Certificates view

The BTS Certificates view allows managing BTS certificates.

Access to BTS Certificates view: Top Menu ► Configuration ► Certificate

Management ► BTS Certificates

The BTS Certificates tab shows information about certificates on the BTS in a table
format:

The Maintenance Association Endpoint (MEP) sends Ethernet Continuity Check

Messages (Eth-CCMs) to its MEP peers according to configured period. MEP expects Eth-
CCMs from every MEP peer. Eth-CCM reports a continuity loss or unintended connectivity
between MEPs. WebEM returns data such as:
ID
Mac address (static)
Mac address (from remote MEP)
Out of sequence CCM
CCM reception
CCM period
Last RDI

Ethernet Link Trace retrieves information about the relationships between

neighboring MEPs or Maintenance Association Intermediate Points (MIPs). It allows detecting
the number of S-OAM-aware hops between two MEPs.

Ethernet Loopback verifies bidirectional connectivity between two peer MEPs or

between MEP and MIP.

port, R&D service port or service account Secure Shell (SSH), as well as change the BTS
R&D parameters.

10.1 Calibrate EPIMC FHS

The Calibrate EPIMC FHS tab allows you to calibrate passive intermodulation
cancellation (PIMC) for a fronthaul switch.

Acces to Calibrate EPIMC FHS: Procedures ► Calibrate EPIMC FHS

The PIMC functionality is based on the PIMC engine. The hardware and software of the
engine monitor the downlink signals coming from the Nokia AirScale system module and
compute a PIM model in real time. The PIMC engine intercepts the uplink signals coming
from radio modules, synchronizes any PIM interference using the PIM model, and subtracts
the PIM noise or interference according to the identified model. This reduces the uplink PIM
interference, and a cleaner signal is sent to the system module.

In order for this functionality to work properly, calibration is required. To perform

calibration, click a dedicated button next to the fronthaul switch (FHS). Calibration results
are displayed under the table listing the available FHSs, as shown in Figure: Calibrate EPIMC

13. FAQ about WebEM

A list of answers to the most common questions about WebEM

Is Web Element Manager the same tool as ADMIN?

Web Element Manager is an evolution of the ADMIN tool that was delivered in release LTE
16A. Starting from release LTE 19/SRAN 17A, Web Element Manager has been enhanced with
parity to BTS Site Manager and became the official Element Manager.

Is BTS Site Manager be available in releases LTE 19 and subsequent ones?

No. Web Element Manager is the only Element Manager to be used.

The ADMIN tool was accessible over port 3600. Is Web Element Manager
accessible in the same way?
Starting from release LTE 19/SRAN 17A, Web Element Manager is deployed on default
HTTPS port, 443. Modern browsers do not require the user to provide a port whenever
referring to the default port, so it is possible to open both
https://mplaneIpOrLmpIp:443 or just https://mplaneIpOrLmpIp.

How to log in to Web Element Manager?

To log in to Web Element Manager, use the same credentials that were used before to log in
to BTS Site Manager.

Is the communication between Web Element Manager and BTS secure?

Yes. Web Element Manager uses Hypertext Transfer Protocol Secure (HTTPS) and Web
Socket Secure (WSS).

What happens if more than one user executes the same operation at one
time?
In practice, a request comes to the BTS first and it gets executed, while the other requests
get rejected. The user is notified about the fact that their request has been rejected.

152 © 2022 Nokia. Nokia Confidential Information Issue 15A

Use subject to agreed restrictions on disclosure and use.

WebEM User Guide

However, no additional info with the reason for rejection is to be provided.

Is it possible to log in to the application with read-only access?

Yes. There is a dedicated account profile that must be first activated via account
management view, which has read-only access. In addition to it, it is possible to manually
downgrade one's own privileges during the login process by selecting an adequate flag.

What access levels are currently supported?

Currently, there are four different access levels supported: BTS Read Only User, BTS
Application Administrator, BTS Security Administrator, and BTS System Administrator.

Is it possible to communicate with other connected users?

No. There is no “chat” functionality implemented in the Web Element Manager. However, it is
possible to browse the list of already connected users in a dedicated view (Sessions List).

Are the actions triggered by Element Manager atomic?

Yes. For example, even if during the recommissioning procedure multiple objects are being
edited, the whole procedure is atomic.

Is it possible to dump configuration from given timestamp?

Yes, simply select a given timestamp in a timeline component (the left side panel of
application), go to Parameter Editor, and save the configuration from there. Please note that
only one timeframe can be selected at a given time. If anything is selected in the timeline
panel, then the latest configuration is exported.

Is it possible to see the current number of active data sessions and VoLTE
calls?
In WebEM GUI and WebEM Remote Tool, you can check the average number of active UEs per
cell during the measurement period (15 minutes by default). UE is considered as active if at
least a single non-GBR DRB has been successfully configured for it. The same value can be
obtained by checking the value of counter M8051C57 CELL_LOAD_ACTIVE_UE_AVG.

WebEM User Guide

Does the RUEM log contain login information of the user that triggered an
operation?
Yes, it does.

Is it possible to export historical changes from the application to check the

state of BTS offline?
Yes. It is possible either via the “Save ims2” button on the timeline (changes fetched by
WebEM during the session) or via the IMSnapshot/Snapshot procedure (changes fetched by
BTS itself starting from the start-up procedure).

Why the size of Web Element Manager logs (ims2 file) differs when it is saved
by the application or fetched by the IMSnapshot/Snapshot procedure?
An ims2 file fetched from the BTS is a compressed one.

Is it possible to check what the state of BTS was prior to the connection?
Yes. Once the connection is established, there is a pop-up window in the timeline
component, where the load history is shown for all prior connections.

Is the interface between Web Element Manager and BTS opened and
published?
No. The interface between WebEM and BTS is binary; it is not intended to be used by third
parties. For automatization purposes, WebEM Remote Tool (former BTS CLI) should be used.

Is there a support for real-time counters?

Yes. Selected counters are reported in the Real-time Measurement view.

Is validation mandatory for plan activation?

Yes. The validation phase is mandatory to trigger plan activation although its results may be
skipped.

WebEM User Guide

Where can I find a manual for Web Element Manager?

The manual for Web Element Manager is available in Discovery Center. It can also be
downloaded from the BTS, via the “Download Help” functionality in the application.

Is it possible to send the plan first and activate it later?

Yes. It is possible to send one plan/delta to the BTS to activate it later. Please note that the
newer plans/deltas overwrite the previous ones.

Is it possible to attach notes to plans, especially those intended to be

activated later?
No. There is no such functionality yet.

Does Web Element Manager support extracting a GSM configuration file for
LTE & GSM sharing feature?
Yes, it does.

Does Web Element Manager allow checking alarm history?

Yes, but indirectly. You have to first load the history prior to the connection.
