摘要： In a network system including at least one mobility anchor point (MAP) for managing mobility of a mobile node (MN) and a plurality of routers connected to the at least one MAP in a hierarchical structure, the MAP sends a MAP option to at least one router located on a higher level than the MAP. When receiving the MAP option, the router located on the higher level sends an updated MAP option to neighboring routers, after incrementing a predetermined upward value comprised in the MAP option. MAPs distributed in the network system can deliver MAP options regardless of the hierarchical structure of routers, and hence the MN can maximize its location privacy. Because the MAP performs MAP domain announcement using a DOMAIN option, service use of routers outside the MAP domain can be limited, and the number of times that a MAP is changed can be reduced.

摘要： Disclosed is a system for providing handover of a mobile node in a wireless network supporting Mobile IP (Internet Protocol). The mobile node sends, when handover is needed, a request for neighbor access router information to a first access router currently communicating with the mobile node, and selects, if the neighbor access router information is received, a second access router serving as a target access router using the received neighbor access router information. The first access router exchanges access router information with a neighbor access router, provides neighbor access router information to the mobile node upon receiving the neighbor access router information request from the mobile node, and redirects data to be delivered to the mobile node to the second access router to which the mobile node will be handed over. The second access router forwards data to be delivered to the mobile node, received from the first access router, to the corresponding mobile node.

摘要： A security management method in a mobile communication system supporting Proxy Mobile Internet Protocol (IP). In the security management method, a Mobile Node (MN), a Serving Packet Data Service Node (S-PDSN), and an Authentication, Authorization and Accounting (AAA) server generate a security key of the Proxy Mobile IP. Upon receipt of information for authentication of a security key from the MN, the S-PDSN sends an access request message to the AAA server and receives information for verification of the security key. The S-PDSN sends a first message for requesting verification of the security-related key to a Home Agent (HA). The HA verifies the security-related key through the AAA server and sends a second message to the S-PDSN when the security-related key is verified. The S-PDSN sends a message indicating initiation of the Proxy Mobile IP, to the MN.

摘要： A method of adjusting the transmission time of data in a CDMA communication system. A UE (User Equipment) measures the time difference between the received time of a downlink DPCH (Dedicated Physical Channel) and the transmitted time of an uplink DPCH and reports it to an RNC (Radio Network Controller). The RNC transmits transmission time adjustment information to a node B and the UE if the time difference is out of a predetermined range. The node B then adjusts the transmission time of the downlink DPCH according to the transmission time adjustment information and transmits the downlink DPCH at the adjusted time. The UE receives the downlink DPCH by adjusting a search time for the downlink DPCH according to the transmission time adjustment information.

摘要： A mobile communication apparatus having an antenna array and a mobile communication method performed in the mobile communication apparatus, wherein the mobile communication apparatus includes a base station and mobile station, each having an antenna array. The mobile station measures the downlink characteristics of a channel for each antenna from a signal received from a base station, determines long-term information in which the correlation property of the channel for each antenna has been reflected from the measured downlink characteristics, transforms the long-term information into a feedback signal, and transmits the feedback signal to the base station. The base station receives the feedback signal, restores the long-term information from the received feedback signal, performs basis mapping and basis transformation on a dedicated physical channel signal using the restored long-term information, adds the basis-mapped and basis-transformed signal to each of pilot channel signals, and transmits the addition results to the mobile station.

摘要： A method for HARQ reordering in Enhanced Uplink Dedicated Channel of WCDMA system includes following steps: locating the soft combination buffer in the Node B and the reordering buffer in the SRNC; locating the HARQ entity in the Node B; locating the reordering queue distribution entity, the reordering entity and the disassembly entity in the SRNC. This invention adopts the separation technology of the soft combination buffer and the reordering buffer, the separation model can not only ensure the diversity gain, but also reduce the receiving delay and save the buffer space. Three mechanisms (timer mechanism, window mechanism and SBI mechanism) are proposed to prevent the blocking of the reordering buffer, which degrades the blocking to the least level, improves the receiving efficiency and the system performance. Aiming at the SBI mechanism, the invention proposes the new DCH data frame structure on the Iub interface and the Iur interface.
