<h1>CCCH Load Statistics</h1>

<p>The Common Control Channel (CCCH) is responsible for transferring
the data between all mobiles and the BTS. This is necessary for the implementation
of call origination and call paging functions. The CCCH consists of the following:</p>


<ul>
<li><p>Random Access Control Channel (RACH)
is the uplink used for gaining access to the system when initiating a call
or responding to a page.</p>
</li>
<li><p>Paging channel (PCH) and Access Grant
Control Channel (AGCH) operate in the downlink direction to the mobile. The
PCH is used to page an MS from the system.</p>
</li>
</ul>


<p>The AGCH is used to assign dedicated resources to an MS
such as a Standalone Dedicated Control channel (SDCCH).</p>


<p>The CCCH load statistics gives information about paging
and RACH load. Statistics can be used, for example, to indicate when there
is a requirement for changing of parameters NBR OF BLOCKS FOR ACCESS GRANT
(AG) and NBR OF MULTIFRAMES (MFR).</p>


<p>This feature is an enhancement to the Resource Access measurement.
The following counters are added:</p>


<ol class="type-odd">
<li type="1"><p>Maximum paging buffer capacity</p>


<p>This counter indicates maximum paging buffer occupancy
percentage during the reporting period.</p>
</li>
<li type="1"><p> Average paging buffer capacity</p>


<p>This counter indicates the average paging buffer occupancy
percentage during the reporting period.</p>
</li>
<li type="1"><p>Delete paging command</p>


<p>This counter tells the number of the delete paging commands.</p>
</li>
</ol>
