Recently, densified small cell deployment with overlay coverage through Heterogeneous Networks (HetNets) has emerged as a viable solution for 5G mobile networks. Cell Outage Detection (COD) which is the essential functionality in Self-Organizing Network (SON) is designed to autonomously deal with unexpected faults. Typical methods for detecting cell outage are usually based on Manual Drive Tests (MDT)...
Load balancing is one of the key target of LTE Self-Optimization Network (SON). In this paper, we propose a load balancing method for LTE downlink network, namely Load Vector Minimization based Load Balancing (LVMLB) method. Load Vector (LV) is a vector whose elements are the load values of cells and sorted in descending order. The order of LVs is defined by the lexicographical order. The smaller...
Green communication has been a hot issue with the energy consumption of ICT industry continuously growing. To achieve the goal of energy saving, base station sleep schemes are extensively investigated; however, they are hard to implement in actual commercial network for the risk of losing of users. So in this paper, we try another way to improve the energy efficiency of LTE network by interworking...
