    • An apparatus and a method for handover in a broadband wireless communication system supporting a Mobile Relay Station (MRS) are provided. The method includes transmitting a Connection ID (CID) of Mobile Stations (MSs), the CIDs pre-allocated by a target BS, to the MSs; sending a resource allocation message comprising uplink resource allocation information for bandwidth request of the MSs, to the MSs; receiving a bandwidth request message which comprises security authentication information of each MS, from the MSs using an uplink resource allocated through the uplink resource allocation information; and aggregating bandwidth request messages of the MSs and sending a ranging request message comprising the security authentication information and bandwidth request information of the MSs to the target BS. Thus, the handover delay time, which is inevitable for the bandwidth request in the conventional connection set-up procedure, can be reduced, and the handover with the reliability guaranteed can be achieved by allowing the security related processing in the network re-entry procedure.
    • 提供了一种在支持移动中继站(MRS)的宽带无线通信系统中切换的装置和方法。 该方法包括将移动站(MS)的连接ID(CID)(由目标BS预先分配的CID)发送给MS; 向MS发送包括用于MS的带宽请求的上行链路资源分配信息的资源分配消息; 从使用通过上行链路资源分配信息分配的上行链路资源的MS接收包括每个MS的安全认证信息的带宽请求消息; 并且聚合MS的带宽请求消息,并向目标BS发送包括MS的安全认证信息和带宽请求信息的测距请求消息。 因此,可以减少在常规连接建立过程中对于带宽请求是不可避免的切换延迟时间,并且可以通过允许网络重入步骤中的安全相关处理来实现具有可靠性保证的切换 。
