摘要：Femtocell is a small cellular base station in home, a low-power wireless access point designed for use inresidential or small business environment, this technology is a promising solution for operators to improvenetwork performance, and the deployment of a femtocell is a key for bandwidth limitation and coverageissues in conventional mobile network system. Therefore, the inter-cell handover process will become morecomplex, frequent and time-sensitive with the introduction of femtocells in cellular networks. This paperpresents the architecture of LTE femtocell networks and investigates the different scenarios in the handoverprocedure. Especially, the mobility of user from macrocell to femtocell which is quite difficult due to thelarge number of candidate femtocells in the coverage area and the characteristics of the femtocell entity, Inorder to achieve the optimize procedure handover decision policy based on using the advantage of theentity HeNB Policy Function to select and make decision of handover based on different constraint to makethe optimal decision about the target femtocell to mitigate the unnecessary handovers, hence we describethe decision policies rules as well as the handover signalling flow furthermore, an analytical model waspresented for the handover signalling cost.
