Information Modeling and Autonomic Configuration Management of Femto Network

Operating and maintenance for femto network is becoming one of the main challenges for telecommunication operators as the femto base station (BS) is indoor, portable, distributed, switching on and off frequently. According to the characteristics of femto network, a management information model (MIM) is proposed to provide information support for management of femto network, including managed objects, management information, measurements and their monitoring granularities. Since the link between femto BS and femto gateway (FB-FBGW) changes dynamically, FB-FBGW model adopts a status attribute to keep instance of the link stable, which would be helpful for operators to aggregate traffic volume over one link conveniently and quickly. Based on the MIM, a femto network autonomic configuration management system (FACMS) with its architecture is given. The MIM is validated by illustrating autonomic configuration procedure of femto BS with FACMS. FACMS could fulfill autonomic configuration of femto BS considering radio environments. Comparing with traditional fixed method, FACMS moves the optimization procedure of radio environments ahead to avoid potential interference, which help to improve transmission efficiency and quality of telecommunication services.
