With the development of heterogeneous networks, small cell is introduced into LTE-A networks to satisfy the demand of user equipments (UEs) with various traffic. Due to the existence of small cells and multi-traffic UEs, traditional mobility load balance (MLB) schemes have not been suitable for the current LTE-A network. By reconfiguring the handover(More)
Heterogeneous Network (HetNets) could enhance the performance of 3GPP LTE-A such as system capacity and network coverage. However, it also brings complex mobility management problems like higher Handover Failure (HF) rates. The traditional method is modeling the Handover (HO) trigger locations and HF locations as co-centric circles so that HF and No(More)
The mobility robustness optimization can significantly enhance the quality of service in scenarios characterized by dense uncoordinated deployment of small cells, as targeted by future 5th generation (5G) radio access technology. Current solutions mostly rely on priori knowledge and rule based algorithms, these solutions do have achieved good performance.(More)
Rapid demands for large capacity services and shortage spectrum resources have motivated the deployment of small cells in LTE-A network. Small cells are low-cost, low power nodes with limited coverage region, as the existence of small cells, more sophisticated network architecture increases the difficulty in dealing with mobility management.
