specific Embodiment approach
[0041] Hereinafter, a handover method using a mobile relay station (MRS) according to an embodiment of the present invention will be more fully described with reference to the accompanying drawings.
[0042] Figure 5 An MRS-initiated handover (HO) procedure according to an embodiment of the present invention is illustrated.
[0043] refer to Figure 5 , when handover is necessary, the MRS 510 transmits a handover request message to the serving base station (serving BS) 520 (S550). The handover request message includes an identifier (ID) of the MRS 510 . The ID of the MRS may include a Basic Communication Identifier (Basic CID) of a Media Access Control (MAC) header. MRS510 uses the existing message MOB_MSHO_REQ defined in IEEE 802.16e or a newly defined message.
[0044] It is assumed that the serving BS 520 previously knows the ID of the MRS 510 and the IDs of the mobile stations (MS) 500 and 502 attached to the MRS 510 (eg, CID of the MAC header) through the backbone ne...
