<h1>Intelligent Directed Retry</h1>

<p>Intelligent Directed Retry feature works in a similar way
to the Directed Retry feature except its design makes it suitable in situations
when the network operator provides different service for different subscribers.</p>


<p>Subscribers are classified to be either GSM subscribers
or MCN (micro cellular network) subscribers. The cells are also classified
to GSM cells and MCN cells. Full mobility is provided for GSM subscribers.
The mobility of MCN subscribers is limited, and they are allowed to establish
call only in MCN cells. However, a MCN subscriber can be handed over also
to a GSM cell.</p>


<p>Subscriber classification is based either on the MS power
capability (MS classmark) or the defined subscriber priority PIE (a priority
information element).</p>
