<h1>Overview of Nokia Base Station Subsystem</h1>

<p>Nokia Base Station Subsystem Description describes Nokia
solution for the GSM network's Base Station Subsystem (BSS). The purpose of
this description is to give a general overview of the parts and operations
of Nokia BSS. In addition, other operational entities and services related
to the BSS are described.</p>


<p>In this description, the abbreviation GSM stands for the
GSM 800, GSM 900, GSM 1800 and GSM 1900 systems. In addition, GSM 800/1900,
GSM 900/1800 and GSM 800/1800 for Nokia UltraSite EDGE Base Station and for
Nokia MetroSite EDGE Base Station are presented.</p>


<p>Nokia Base Station Subsystem consists of the base station
controller (BSC), transcoder submultiplexer (TCSM), base station (BTS), cellular
transmission (CT), power systems, antenna line, the network service and management
system (Nokia NetAct) and network planning. In this document, general network
element names are used for Nokia equipment.</p>


<p>Nokia can provide a complete BSS network including:</p>


<ul>
<li><p>Radio network elements: BSC and a wide
range of BTSs.</p>
</li>
<li><p>Integrated cellular transmission including
short- and long-haul microwave radios, copper-based transmission and PDH cross-connection.
For optical transmission there are full SDH product families from Marconi
and Tellabs.</p>
</li>
<li><p>Integrated and stand-alone power systems,
battery backup and site support solutions</p>
</li>
<li><p>Full range of antenna line elements</p>
</li>
<li><p>GSM-WCDMA Inter-System Handover software
application, which enables the interworking between the 2G and
3G networks.</p>
</li>
<li><p>Management of all of the above with
Nokia NetAct network service and management system.</p>
</li>
</ul>
