Paper Title
Handover Latency Reducing Techniques in LTE-Advanced High Speed Rail Networks
  Manoj C K,  T Chandhini

Handover is a technique that shifts an on-going call from one cell to another as the user moves the coverage area of a cellular system. Handover mechanism needs to be designed according to the nature of the network. Nowadays, mobile relay technique has been playing an important role in LTE-Advanced (LTE-A) high-speed rail networks. In the system there are a number of mobile relays deployed in a train. Mobile relays coordinate control of User Equipment (UE) devices in the train. UE devices connect to the mobile relays rather than the outside evolved NodeBs (eNBs).In very high mobility scenarios, where the train travels at high speed, the mobile relays undergo frequent handovers between serving donor eNBS (DeNBs). This unavoidable handovers may seriously affect the performance of the network. This paper suggests an enhanced handover scheme, which contains an enhanced measurement procedure and a group in-network handover procedure. The enhanced measurement procedure can accelerate the measurement procedure when the mobile relay predicts their moving direction. In the core network, the similar in-network handover procedure can be aggregated by the group in-network handover procedure.

Keywords- High-speed rail, handover, mobile relay, LTE-Advanced.
