Soft Site Moving and Cutover in WCDMA Network
Sun Yi · ZTE communications · 2007
Traditionally, when a radio network site is moved, 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 low-risk and fast solution to site moving and cutover. ZTE Base Band Unit and Remote Radio Unit (BBU+RRU) Base Station adopts distributed structure and combines full frequency reuse of the WCDMA system to implement soft site moving and cutover conveniently. The solution is to build an overlay network and make a one-time cutover without any impact on the running of the existing network. Moreover, it supports timely fallback, and can considerably simplify the site moving and cutover operation and lower the network risk.
