<h1>Mobile Station Capability Indication</h1>

<p>Distribution of the mobile stations in the network is a
significant factor when operators are dealing with capacity issues, network
planning, or introducing new services. Operators have a need for the information
on how the mobile stations, with diverse capabilities, are distributed in
the network.</p>


<p>Mobile stations with various functions and capabilities
are roaming in the network. When the operator has precise knowledge of these
mobile stations and their locations, the demand on the resources required
by the different types of mobile stations can be taken into account during
network planning.</p>


<p>The purpose is to provide cell specific information on
the capabilities of the mobile stations. In this new measurement, mobile stations
are separated into groups based on the following features: revision level,
supported frequency band, and multislot capability.</p>

<div class="topic">
<h2>Revision
level</h2>

<p>The mobile stations can be distinguished with the aid of
the revision level. This information shows if the MS is phase 1 or phase 2
type. In the MS capability indication, the number of TCH reservations and
the cumulative MS reporting times of the mobile stations of different revision
levels are measured.</p>
</div>


<a name="mar174116432" shape="rect"></a>
<div class="topic">
<h2>Frequency
band support</h2>

<p>The mobile stations can support different frequency bands.
It is possible to distinguish five different types of mobile stations:</p>


<ul>
<li><p>Single Band GSM 900 MS</p>
</li>
<li><p>Extended Band GSM 900 MS</p>
</li>
<li><p>Single Band GSM 1800 MS</p>
</li>
<li><p>Dual Band MS</p>
</li>
<li><p>Tri Band MS.</p>
</li>
</ul>

</div>


<p>In the MS capability indication, the number of TCH reservations
and the cumulative MS reporting times of the mobile stations supporting the
different frequency bands are measured.</p>
</div>


<a name="mar174118533" shape="rect"></a>
<div class="topic">
<h2>Multislot
Capability</h2>

<p>In this MS capability implementation, the multislot classes
from 1 to 18 are separated. The number of TCH reservations for all these classes
is measured. Also, the total number of TCH reservations of both multislot
capable and incapable mobile stations is measured.</p>


<p>Below are examples of statistics based on the frequency
bands the MS is able to support (single band, dual band, tri band).</p>


<p>These statistics help the network operator with network
dimensioning:</p>

</div>


<p>This information can be used in network planning when the
demand on the resources required by the different types of mobiles is evaluated.</p>
