Traditionally,when a radio network site is swapped,it is necessary to interrupt existing services and perform a step-by-step serial cutover,which involves complex arrangements and huge resource investments.Therefore,there is an urgent need to discuss a fast and low-risk solution for site moving and cutover.ZTE Base Band Unit and Remote Radio Unit(BBU+RRU)Node B adopts distributed structure and combines full frequency reuse of the WCDMA system to conveniently implement soft site moving and cutover.The solution is to build an overlay network and make a one-time cutover without any impact on the operation of the existing network.Moreover,it supports timely fallback,and can considerably simplify the site moving and cutover operation and lower the network risk.
