<p class="p_NoramlTest"><span class="f_NoramlTest">&nbsp;</span></p>
<p class="p_NoramlTest" style="line-height: 1.50;"><span class="f_NoramlTest">This function enables certain outgoing call to be routed to different destination directory numbers depending to its incoming routing zone. A routing zone is associated with a set of radio cells or trunk groups. Each routing zone can have its own dialing prefix set, routing plan, announcement plan, and call control options. Routing zone offers the possibility to route a call to the nearest service point depending on the location of the mobile subscriber or incoming PSTN trunk group.</span></p>
<p class="p_NoramlTest" style="line-height: 1.50;"><span class="f_NoramlTest">A uniform service number can therefore be assigned to different service points which defined in the independent routing zones. A subscriber who dials this service number will be connected to the specific service point assigned to his current location. An example of a service point is the vehicle recovery service.</span></p>
<p class="p_NoramlTest"><span class="f_NoramlTest">&nbsp;</span></p>
<p class="p_NoramlTest" style="line-height: 1.50;"><span class="f_NoramlTest">With this function it is possible to establish a number of service points and assign the associated local directory numbers to the service number. A small number of the total service numbers possible can be defined as emergency numbers.</span></p>

<p class="p_NoramlTest"><span class="f_NoramlTest">&nbsp;</span></p>
<p class="p_NoramlTest" style="line-height: 1.50;"><span class="f_NoramlTest">For example, the system route all of the MO calls to a third party prepaid system to implement realtime wireless IMSI based account control and monitoring. The callers' account balances will be audited. After that, the call request will be route back to the system transparently. </span></p>
<p class="p_NoramlTest"><span class="f_NoramlTest">&nbsp;</span></p>
<p class="p_NoramlTest" style="line-height: 1.50;"><span class="f_NoramlTest">The local MSISDN is 9xxxxx, the PSTN number is 8xxxxx. Two Routing Zones need to be configured in this scenario, refer to the figures below:</span></p>
