    Abstract
  • In order to improve the successful handover probability of GSM-R (GSM for railway) system, an enhanced handover scheme with shared-relay stations was put forward. In the scheme, shared-relay stations were applied to improve the signal quality of target base stations in the signal overlapping region among adjacent base stations and to separate the received mixed signals from different base stations, which could decrease the handover misjudgment resulted from signal fluctuation. Simulation result shows that the scheme can trigger handover appropriately in advance about 500 m, so that there is longer distance for completing handover process when train is traversing through the overlapping region. Because of better signal quality, ping-pong effect eliminates, handover failure probability reduces to 10-6, thereby, successful handover probability increases. Meanwhile, considering the system interference, shared-relay stations can not be used in the network with the less reuse factor than 2.2 tabs, 9 figs, 13 refs.
