Abstract

See full text

Providing mobility support of UEs that are served by mobile relay base stations, by providing handover of a UE for data traffic only between two mobile relay base stations. Exchanging information between the source and target mobile relay stations of the concerned UE in handover, and/or the corresponding donor base stations if applicable. The handover is triggered by any of the following: based on UE's measurement report, the signal quality of a neighbor cell is better than the current serving cell; based on the measurement of the serving mobile relay base station, the signal quality of the link to the UE is worse than a certain threshold; or based on the measurement of the serving mobile relay base station, the signal quality of a neighbor cell is much better than the current donor base station.
