Abstract: An apparatus is capable of supporting an intra-BS handover of a Mobile Station (MS) that can distinguish a Relay Station (RS) and a Base Station (BS) in a multi-hop relay broadband wireless communication system. A handover of an MS in a multi-hop relay wireless communication system includes receiving a neighbor advertisement message. When a handover command message that initiates a handover to a target node is received, information on a target node is acquired, and an upper BS of the target node is identified. When the identified upper BS of the target node is the same as an upper BS of the serving node, control information that has been previously used in a serving node is used in the target node, and communication with the target node is performed.

Abstract: An apparatus and method for an admission control for a service flow in a broadband wireless access communication system using a multi-hop relay scheme is provided. In a method for operating a relay station in a broadband wireless communication system using a multi-hope relay scheme, a request message requesting an admission control decision for a service flow is received from an upper node. It is determined whether a requested QoS parameter set included in the request message is supportable. If the requested QoS parameter set is supportable, the request message is forwarded to a subordinate relay station corresponding to a next hop in a data transmission path. If the requested QoS parameter set is unsupportable, a response message indicating the unsupportability of the requested QoS parameter set is transmitted to a base station.
