Femtocell technology has been proposed to discharge user data traffic from the macrocell to the femtocell and to expand the limited coverage of the macrocell in mobile communications networks. In existing commercial femtocell / macrocellular networks, a widely accepted solution for configuring the location areas (LAs) is to divide the overlapped femtocells with a macrocell into small groups and assign each group a unique LA ID different from the macrocell. Such configuration may reduce the cost of paging in mobility management, but registration signaling overhead increases because of the discontinuous coverage of femtocells. To reduce signaling overhead in the femtocell / macrocellular network, a delay logging (DR) algorithm is proposed which postpones the log until the delay timer expires when the mobile station (MS) moves on the superposed femtocell. Analytical models and simulation experiments are proposed to investigate the performance of the DR algorithm. Our analytical models are generally sufficient to accommodate various MS mobility behaviors. Our study may provide guidelines for operators to establish a delay timer to reduce signaling overhead while supporting the traffic discharge capacity of the femtocell.
Long-Term Evolution (LTE) adopts femtocello technology (ie internal base station) to download data traffic from the macrocell (ie external BS) and extend the radio coverage of the macrocell. In the femtocello / LTE macro cell network, a mobile station (MS) is more likely to perform the handover procedure to switch the RRC connection between femtocells and macrocells. In this article, we propose a Transfer Cost Reduction (RHC) mechanism to achieve two objectives: to avoid frequent handover executions and to increase the ability to discharge femtocell traffic. RHC is considered practical and has been implemented in the femtocell prototype. Based on analytical models and simulation experiments, we investigated the performance of the RHC mechanism. Our study demonstrates that the mechanism of RHC can effectively achieve both goals.
