Mobility Management Survey for Home-eNB Based 3GPP LTE Systems
TLDR
The characteristic of Home-eNB is overviewed and the mobility management issues and the related approaches in 3GPP LTE based Home- eNB systems are described.Abstract:
The specification of the Home Evolved NodeB (Home-eNB), which is a small base station designed for use in residential or small business environment, is currently ongoing in 3GPP LTE (Long Term Evolution) systems. One of the key requirements for its feasibility in the LTE system is the mobility management in the deployment of the numerous Home-eNBs and other 3GPP network. In this paper, we overview the characteristic of Home-eNB and also describe the mobility management issues and the related approaches in 3GPP LTE based Home-eNB systems. Keywords : Home-eNB, 3GPP LTE (Long Term Evolution), Mobility Management 1. Introduction issues of HeNB in 3GPP LTE systems and related approaches A significant interest within the telecommunications industry has recently focused on the femto-cell which is defined broadly as low-cost, low-power cellular base stations that operate in licensed spectrum to connect conventional, unmodified mobile terminals to a mobile operator’s network [1][2][3]. Femto-cell has been actively discussed in 3read more
