    摘要: A method of establishing security association during handover between heterogeneous networks in a radio access system is disclosed. A method of establishing security association before handover with a target base station included in a heterogeneous radio access network is performed comprises transmitting a request message to a service base station, the request message requesting the service base station to transfer authentication related information of a mobile station to a target network authentication server; and receiving a response message from the service base station before the handover with the target base station is performed, the response message including security related information used in a target network.

    摘要: A packet reordering method and a packet transmission method to implement reliable data communication are disclosed. The method of transmitting packets at a serving base station in case of a mobile station performing handover include, receiving a series of packets from an upper layer entity, and transmitting the series of packets one after the other to a target base station, wherein a packet of the series of packets includes an information field which represents whether the packet is the last transmitted packet. When the mobile station performs the I-RAT handover, the target serving station pre-reorders PDU packets, and transmits the reordered PDU packets to the mobile station, such that the mobile station can quickly transmit data without reordering the packets.

    摘要: A method for handover between heterogeneous radio access networks is disclosed. When a multi-mode mobile station performs Inter-RAT handover, pre-authentication is performed before implementing a link layer handover procedure with a target access point. The pre-authentication method has as little an effect on currently served quality of service as possible and the handover is efficiently performed using the pre-authentication method. The pre-authentication is performed through medium independent handover (MIH) and various MIH primitives for pre-authentication are provided.

    摘要: A fast uplink data transmission method for a handover is disclosed. This method effectively uses a handover signal when there is data to be transmitted to an uplink during an Intra Radio Access Technology (I-RAT) handover, such that it quickly transmits and receives uplink data. The method of transmitting uplink data in a wireless access system includes, transmitting a message including an information bit to a target base station by a mobile station during a handover, wherein the information bit indicates whether the uplink data is present, and receiving a radio resource for transmitting the uplink data from the target base station, if the information bit indicates the uplink data is present, wherein the radio resource is allocated by the target base station. So, uplink user data can be quickly transmitted to a destination while the UE performs the handover.

    摘要: A method for performing band handover in a broadband wireless access system is provided. In this method, a terminal in a band AMC mode in which the terminal transmits and receives data through a band selected from among bands to which a modulation scheme and a coding rate are adaptively applied receives channel status information of each band of a neighboring base station. The terminal then performs handover to the neighboring base station while maintaining the band AMC mode if it is determined based on the received channel status information that a channel status of each band of the neighboring base station satisfies a predetermined condition. This band handover method enables handover to be performed for each specific frequency band of a mobile terminal.
