Optimized Handover Mechanism between eNBs and the Dynamic Network of HeNBs in 3GPP LTE

Abstract

This paper presents an optimized handover mechanism from eNodeBs (eNBs) to dynamic home eNodeBs (HeNBs) by introducing a proposed architecture for LTE femtocell network. In addition to that, showing how the dynamic network of femtocells can be established using the concepts of FFR (Fractional Frequency Reuse), ANR (Automatic Neighbor Relation) and the proposed feature of DNL (Dynamic Neighbor List). This gives the advantage of dynamism to HeNBs and so the chance to overcome on one of the most important challenges that face the femtocells, which is the ability of the subscribers to carry their own femtocells for use anywhere. Also, this paper explains a simple analytical model to compare between the standard architecture of LTE femtocell network and the proposed one. This comparison shows that the proposed architecture has a better performance through reducing the signaling load on core network.
