摘要： Provided are an Automatic ReQuest (ARQ) apparatus and method for a multihop system in a broadband wireless access communication system. When the number of ACK MAPs in ARQ feedback information element of ARQ feedback message transmitted from a destination or Multi-Hop Base Transceiver Station (MH-BTS) is not zero, and it is determined that the destination or a lower MH-BTS successfully receives data corresponding to Block Sequence Number (BSN), the BSN is updated with a BSN successfully received at the destination or the lower MH-BTS, and is transmitted to the upper MH-BTS or the source. Accordingly, when the MH-BTS successfully receives the data from the source but the destination fails to receive the data, the source does not retransmit same data to the MH-BTS.

摘要： A method and apparatus of supporting a fast handover in a transport layer is provided. In a network using an SCTP (Stream Control Transmission Protocol), an MN (Mobile Node) acquires a first new IP (Internet Protocol) address after a first handover to a first new network area, stores information about the first handover to the first new network area, and sends (i.e., transmits) a first handover message including the new IP address to a CN (Correspondent Node). If a second handover to a second network area is required, the MN performs the second handover even if a response message for the first handover message has not been received, acquires a second new IP address, stores information about the second handover, and sends a second handover message including the second new IP address to the CN.

摘要： A handover apparatus and method for a multi-hop system in a BWA communication network are provided. In a handover system supporting multi-hop system in a BWA communication network, a BS periodically broadcasts a message with neighboring BS/RS information. When a new BS or RS needs to be added, an RS periodically broadcasts the broadcast message received from the BS with information about the new BS or RS. An MS receives the broadcast message from the RS and requests information about BSs or RSs to which the MS can perform a handover by notifying candidate BSs or RSs for the handover. The candidate BSs or RSs may include a BS or RS not included in the broadcast message, if the MS detects the BS or RS by scanning. The MS selects a target BS or RS based on the BS or RS information received from the BS, and performs the handover to the target BS or RS.

摘要： A method and apparatus for supporting a seamless handover in a transport layer is provided. In a network using an SCTP, an MN notifies a CN of a handover after the handover occurs. The MN receives a handover confirm message from the CN and sends a response message for the handover confirm message to the CN. The MN checks a recipient IP address at which data is received from the CN. If the recipient IP address is a new IP address, the MN changes a primary IP address of the MN to the new IP address. If the recipient IP address is the primary IP address, the MN maintains the primary IP address.
