System information (SI) acquisition is a mandatory component for inbound handover (HO) to closed subscriber group femtocells in LTE/LTE-Advanced networks. In this paper, we analyze theoretically and numerically several existing SI acquisition schemes such as scheduled, semi scheduled and autonomous SI acquisition scheme. We found that using those schemes can result in long measurement gaps; which...
Recently, distributed mobility management (DMM) solutions have been proposed to address the drawbacks of centralized mobility management (CMM) solutions. The Internet engineering task force (IETF) has stated that extending and reusing CMM protocols are one of the considerations for DMM solutions design, where it is less faulty and more effective. Therefore, IETF has proposed a network-based DMM solution...
Due to the increasing demand for higher data rates by mobile users, the deployment of femtocells under macro coverage has been adopted by 3GPP LTE-Advanced systems as one of the main proposals to enhance the network performance in the respects of coverage and capacity improvement especially for indoor users. However the random deployment of femtocells raise the issue of interference between macrocell...
