Research and Realize of High Availability in Femto Communication System

With the continuous development of 3G networks, Femto has gotten more and more attention and development, as a kind of access technology in cellular base station,it improves indoor coverage、cell capacity and relieve network pressure of outdoor macro base station. But how to ensure the efficient and uninterrupted in communication network is a problem which we currently facing. This paper will solve this problem using HA (High Availability) technology, when the computer system or network hardware or software fail, it can switch to the backup system by the switch-over technology to achieve uninterrupted service and maintenance system availability.
