<h2>Purpose</h2>

<p>Activating EQoS requires supported software set negotiations with the
SGSN and a reset of every NSE. If you activate EQoS before creating the Gb
interface, the extra resets are not needed. See <a href="NED?action=retrieve&amp;identifier=dn04111826&amp;edition=1&amp;language=en&amp;coverage=global&amp;encoding=xhtml_1_0&amp;component=data&amp;item=data&amp;pointer=ned_top#ned_top" onclick="sync(this);return true" shape="rect">Activating
Gb over IP</a> for instructions on creating the Gb interface. </p>


<p>Enhanced Quality of Service (EQoS) support in the BSC is controlled
by a licence. </p>

<h2>Before you start</h2>

<ul>
<li><p>Packet Flow Context (PFC) procedures must be supported by the
SGSN before activating EQoS.</p>
</li>
<li><p>The EQoS licence must be installed in the BSC and EQoS must be
in use. For more information on activating licences, see <em>Licence-based
Feature Management</em> below.</p>
</li>
<li><p>PCU2 cards are required before EQoS activation.</p>
</li>
<li><p>The EQoS counters are visible only if the Enhanced Quality of
Service Measurement is activated. For more information, see <em>GSM Measurement
Handling</em> (command group TP ).</p>

<h2>Licence-based feature management</h2>

<p>Licence-based feature management means that the use of certain optional
features is controlled by licences. A network operator who wants to acquire
a licensed feature, buys the licence, installs it in the network element,
and can then activate the feature. One licence file may, in practice, cover
one or more features.  </p>


<p><span class="menupath-sem">Dependencies between licence-based and parameter-based
feature management:</span></p>


<p>Licence-based feature management does not replace parameter-based feature
management entirely. Rather, the two management systems are used side by side.
Some older features, however, which used to be controlled with parameter-based
feature management have been transferred under the control of licence-based
feature management. </p>


<p>A fluent ramp-up of licence-based feature management requires that licence
keys are available on the site for all existing, newly licensed features in
the operator's network. All the software required by a licenced feature needs
to be installed and activated before the feature can be taken into use.  </p>


<p><span class="menupath-sem">Capacity features and on/off features:</span></p>


<p>A licensed feature can be a capacity feature or an on/off feature (non-capacity
feature).  Both these feature types can be time-limited. This means that the
licence covering the feature has a pre-defined expiration date, which is stated
in the licence file The operator can determine how much in advance the system
gives a warning that the licence is about to expire. If the operator does
not define the expiration warning period when installing the licence in the
network element, the system uses the default warning period, which is 30 days.
  </p>


<a name="jan1251316265" shape="rect"></a>
<dl class="caution-notification">
<dt class="caution-caption">Caution</dt>
<dd>It is important to define the warning period so that there is enough
time, between the warning and the expiration of the licence, either to update
the licence or to make a controlled inactivation of the feature(s) covered
by the licence. If the expiration of a licence causes an uncontrolled rampdown
of feature(s), this may result in serious malfunctioning of the network element.</dd>
</dl>


<p>A time-limited capacity licence can be updated by ordering an increment
to the licence. The increment must be installed in the network element before
the original licence expires. Similarly, if an increment is about to expire,
a new increment must be installed before the previous one expires.  </p>


<p>A time-limited on/off feature (non-capacity feature) can be updated
by ordering a continuation licence. This, too, must be installed before the
existing licence expires.</p>


<p><span class="menupath-sem">Alarms related to licence-based feature management:</span></p>


<p>The licence-based feature management system generates the following
kinds of alarms:  </p>


<ul>
<li><p>Alarm 3269 - LICENCE EXPIRATION WARNING is given when a licence
is about to expire. The licence must be updated. </p>
</li>
<li><p>Alarm 3270 - LICENCE EXPIRATION is given, if a time-limited licence
has not been updated before the last day of the expiration warning period.
The licence has expired.  </p>
</li>
<li><p> Alarm 3271 - LICENCE IS NOT VALID is given, if the licence file
is corrupted. The licence file must be replaced with a new, valid file.</p>
</li>
<li><p>Alarm 3272 - LICENCE CHANGE NOT NOTIFIED is given, if the Licence
Management fails to deliver a notification of a change in the licence data.
As a result, the system cannot utilise the updated licence data. The licence
change can be notified manually for example with the 'modify feature state'
command (W7M ). </p>
</li>
<li><p>Alarm 3294 - LICENCE CAPACITY WARNING is given, if the capacity
consumption exceeds a threshold defined for the licence. The capacity consumption
must be reduced, or more capacity acquired. </p>
</li>
<li><p>Alarm 3295 - LICENCE CAPACITY EXCEEDED is given, if the capacity
consumption rises to the maximum level granted by the licence. More capacity
must be acquired, if consumption needs to be increased. </p>
</li>
</ul>


<p>Licence-based feature management functions are handled with <em>Licence
and Feature Handling MML </em>(command group W7).</p>
