Abstract
With the deployment of the Home eNodeB, the handover between femtocell and
3GPP macrocell networks is becoming more important in LTE based networks.
Thousands of femtocells within a macrocell area will create a large neighbor cell
list and an interference problem. Thus modifications of handover procedure and
algorithm for existing networks are needed to improve the performance of both
the femtocell and LTE networks
The novel handover mechanism proposed in this thesis will have a better
performance in the rate of decreasing the signaling load on the core network by
making the node of HeNB GW a more intelligent node. Introducing the concept
of FFR (fractional frequency reuse) in our proposition will improve the
interference problem between the macrocell and its neighbors of femtocells.
This will enhance the data throughput. Also the concepts of ANR (automatic
neighbor relations) and DNL (dynamic neighbor list) and their roles in solving
the problem of defining the neighbors for the macrocell, taking into
consideration the limited number of neighbors that should be defined for each
macrocell. So this will give the femtocell the advantage of dynamism
On the other hand, introducing a simple analytical model to compare between
the standard architecture and proposed one. This gives a proof of the importance
of the proposed architecture and how the introducing of both (Intelligent HeNB
GW) and (X2 Handover instead of S1 Handover) will enhance in performance
improvement. Finally, a detailed and optimized algorithm for the handover scenario from macrocell to femtocell has been showed.
