Abstract:
Themobility of mobile terminals results in the transfer of calls from one cell to another. This transfer could lead to call dropwhen handover is unsuccessful. Call drop minimization techniques are methods of reducing the number of dropped handover callsas well as improve fairness between new and handover calls. This paper studies the effect of combining handover prioritization schemes and retrial queues, as call drop minimization techniques, on calls entering the network. Results show that with the call drop minimization techniques, there is a minimal drop in handover calls.
