摘要： The present invention relates to a wireless network, and more particularly, a method (*“and system”?*) which a mobile station discovers a neighbor network in an Internet protocol based wireless network, a network management server for enabling the method, and a method of operating the network management server. A network management server of a wireless network system, the server including: a neighborhood (NH) database maintaining configuration information with respect to at least one neighbor network; a communication interface receiving a request message for capability/configuration information of the neighbor network from a mobile station which is connected via a predetermined access point or a base station; and a database management unit extracting the capability/configuration information of the neighbor network which is included in the request message by referring to the neighborhood database, and controlling a reply message including the capability/configuration information to be transmitted to the mobile station via the communication interface.

摘要： A mobile network is disclosed in which there exists a Mobile Node (MN), the MN is managed by a first Access Router (AR), and there exists a second AR with a subnet different from the first AR. A method is provided for the MN performing a fast handoff from the first AR to the second AR, which includes receiving a Routing Advertisement (RA) message of the second AR from the first AR, generating an IP address to be used in the second AR using the RA message of the second AR if the MN recognizes that it should perform a handoff from the first AR to the second AR, performing a trigger for using the generated IP address if the movement to the second AR is completed, and transmitting/receiving a Correspondent Node (CN) and data using the IP address.

摘要： A method of configuring and registering an Internet Protocol (IPv6) address in a wireless mobile communication system having a connection-oriented radio link is provided. In an IP configuration method without Duplicate Address Detection (DAD), a Mobile Station (MS) is allocated a unique Connection Identifier (CID) specific to the MS from a serving Base Station (BS), and the MS and BS configure the IPv6 address independently using a known network prefix, a Medium Access Control (MAC) address of the MS, and the allocated CID. The BS registers the configured IPv6 address to a HA on behalf of MS.

摘要： A handover method of a mobile station (MS) in a mobile communication system having MSs and radio access stations (RASs), each of which includes an IEEE 802.16 standard-based medium access control (MAC) layer and an Internet protocol version 6 (IPv6)-based IP layer. The handover method includes the step of gathering IP network information of a neighbor RAS through a message exchange with a previous RAS. A target RAS for handover based on the gathered IP network information of the neighbor RAS is determined, after the target RAS is determined, the previous RAS tunnels data for targeting the MS to the target RAS, Then the tunneled data are received from the target RAS.

摘要： A method of transmitting/receiving a frame between a portable terminal and a base station in a wireless broadband Internet network are provided. More particularly, a method of transmitting/receiving frames can include activating a session between the portable terminal and the base station, removing at least one header information field included in an Internet protocol (IP) datagram after activating the session, adding a network header which sets a predetermined transport connection identifier (TCID) to the IP datagram, generating the frame, and transmitting the generated frame via the activated session. Preferably, the frame is generated in any one of the portable terminal and the base station, and transmitted to the other one of the portable terminal and the base station.
