<h1>IDR and TR as per PIE (Priority Information Element)</h1>

<p>The BSC can classify mobile subscribers (MS) in two classes:
Micro cellular Network (MCN) subscribers and GSM subscribers. Initially, the
subscriber types were distinguished with the help of the MS power class.</p>


<p>An alternative method for distinguishing between the subscriber
types is the use of  Priority Info Element (PIE). The new subscriber class
can be defined in addition to the GSM and MCN subscriber classes by using
this PIE information: priority subscriber.</p>


<p>The MSC determinates the type of the subscriber and sends
the corresponding PIE to the BSC in the Assignment Request and Handover Request
messages.</p>
