A Survey on Self-Organizing Networks

PhD Qualifying Examination


Title: "A Survey on Self-Organizing Networks"

by

Mr. Wei WANG


Abstract:

As the demands for mobile phone access to the data services are expanding, 
advantages in cellular services can be gained by offering enhanced user 
experience through cost-effective broadband mobile access. The approach 
towards cost-effective broadband mobile access is to maximize total 
performance of networks, by providing not only wireless access with higher 
performance but also more efficient operation and maintenance (O&M). The 
vision of self-organizing networks (SON), which is in line with the views 
of 3GPP (3rd Generation Partnership Project) and the NGMN (Next Generation 
Mobile Networks) group, is that future radio access networks needs to be 
easier to plan, configure, manage, optimize and heal, in order to improve 
O&M. It aims at reducing the cost of installation and management by 
simplifying operational tasks through automated mechanisms, such as 
self-configuration, self-optimization and self-healing. In this survey, we 
first introduce some background knowledge about SON. Then we summarize key 
challenges in applying SON in cellular systems from technical 
perspectives. Existing research work and our considerations are presented 
to give potential solutions for these challenges.
