MS HANDOVER IN TRANSPARENT RS AND NON-TRANSPARENT RS COEXISTING MULTI-HOP RELAY NETWORK

摘要

A method for handover between a non-transparent RS(Relay Station) and a transparent RS in a multi-hop network is provided to shorten a delay time, reduce the frequency of handover, and minimize radio interference by presenting a complementary MS(Mobile Station) handover procedure in an environment where two kinds of RSs exist together. If the access station of an MS has the same preamble/FCH/MAP as a target access station in a multi-hop relay network where a transparent RS sharing a preamble with a BS(Base Station) and a non-transparent RS using a different preamble from the BS exist together, the MS cannot recognize that handover occurs. In this case, RSs and an MR-BS should transparently execute handover from the MS's standpoint. If a path directly connected to the MS from an MR-BS/Anchor BS doesn't exist, a handover procedure using the transparent RS should be applied.
