The Call Release proc<strong>ed</strong>ures ensure that resources allocat<strong>ed</strong> to a call are free for reuse when they are<br />
no longer requir<strong>ed</strong> by the current call.<br />
Call Release proc<strong>ed</strong>ures are requir<strong>ed</strong> when:<br />
A call is finish<strong>ed</strong> and either the call<strong>ed</strong> or calling party hang up<br />
An MS is turn<strong>ed</strong> off<br />
A call is hand<strong>ed</strong> over and the resources for the original call are releas<strong>ed</strong><br />
A call is modifi<strong>ed</strong> and the resources for the original channel are releas<strong>ed</strong><br />
There is an operator intervention, such as a channel being block<strong>ed</strong><br />
There is a failure<br />
There is a radio link failure<br />
The system detects a LAPDm failure.<br />
If a call is terminat<strong>ed</strong> normally, the Call Release proc<strong>ed</strong>ures are trigger<strong>ed</strong> automatically. If the call is<br />
terminat<strong>ed</strong> abnormally, the system has to detect that the resources are no longer requir<strong>ed</strong> and release<br />
them.<br />
