Self Organizing Network

As demand for wireless access to the Internet and Internet-based services is expanding, competitive advantages in the mobile business can be gained by offering enhanced user experience through costeffective broadband mobile access. A promising approach is to maximize total performance of networks, i.e., provide not only wireless access with higher performance but also more efficient operation and maintenance (O&M). The Self Organizing Network (SON) introduced as part of the 3GPP Long Term Evolution (LTE) is a key driver for improving O&M. It aims at reducing the cost of installation and management by simplifying operational tasks through automated mechanisms such as self-configuration and self-optimization. While supporting 3GPP standard on LTE/SON, NEC’s hybrid management architecture will enhance robustness, scalability and response of self-X functions and enable effective integration into the existing operations. Moreover, NEC’s self-optimization will enhance user perceived qualities by optimizing intra-cell radio qualities with a radio planning tool.
