摘要： Conventional position estimation methods require the deployment of more fixed anchors in order to increase the accuracy in a crowded indoor environment, or they suffer from inaccuracies due to multipath fading. The present invention overcomes the problems associated with the prior arts by selecting one or more mobile nodes as virtual anchors when estimating the position of a target mobile node. This takes advantage of the fact that mobile nodes are closer to the target mobile node than the access points in most typical deployments, thus eliminating the need to deploy more access points or fixed anchors for the purpose of position determination. After obtaining an initial estimate of the position of the target mobile node, the target mobile node can serve as virtual anchors to estimate the positions of other mobile nodes, which can then be used to further refine the position estimate of the target mobile node.

摘要： A mobile terminal that ensures smooth, continuous communications sessions even when in transit, regardless of base station capabilities and functionalities, in a packet-switched data communications network. With this terminal, each of a plurality of lower interfaces 101-1 to 101-M, when its associated access mechanism is in an active state, can obtain a connection to packet-switched data communications network 150 using its home-address HoA.1 or its care-of-address CoA.BS1. When lower interface 101-a loses its connection obtained using the care-of-address CoA.BS1, multiple access decision unit 104 instructs mobility support unit 102 to set up a binding of the home-address HoA.1 and either one of the home-address HoA.2 and the care-of-address CoA.BS2 of another lower interface 101-b. Mobility support unit 102 sets up the binding according to the instruction from multiple access decision unit 104.

摘要： A technology is disclosed for certainly performing dynamic routing and error checking processes in the mobile network. According to this technology, the home agent sets up a Binding Acknowledgement message with a smaller Lifetime value when receiving a Binding Update message from a mobile router. During this smaller Lifetime, the mobile router can send a Routing Update message to the home agent. Thus, the home agent, for example, can check consistency of prefix information specified in the Biding Update with route installed by the Routing Update message. The present invention can be applied to both two distinct modes (explicit mode and implicit mode) that prefix information is specified in the Binding Update or not.

摘要： A technology is disclosed with which a mobile terminal moving in a PMIP domain receives various types of prefixes and selects a type of an address to be configured, and route optimization is performed without adding a signaling load on the PMIP domain. According to the technique, when connecting with a home domain, a MN (310) requests a plurality of prefixes. When a MAG (320) makes an AAA server (340) authorize the MN and receives a notification instruction of the plurality of prefixes from the AAA server, the MAG 320 makes a notification of the plurality of prefixes with a RA message (364), for example. The MN configures a plurality of addresses (for example, a PMIP address including a PMIP domain prefix or a global address including an on-link prefix) from the plurality of prefixes received and notifies the MAG of the same. The MAG registers a plurality of bindings relating to the plurality of addresses with a LMA (330).
摘要翻译：公开了一种在PMIP域中移动的移动终端接收各种类型的前缀并选择要配置的地址的类型的技术，并且在PMIP域上不添加信令负载的情况下执行路由优化。根据该技术，当与归属域连接时，MN（310）请求多个前缀。当MAG（320）使AAA服务器（340）授权MN并从AAA服务器接收到多个前缀的通知指令时，MAG 320通过RA消息（364）通知多个前缀，例如。 MN从接收的多个前缀配置多个地址（例如，包括PMIP域前缀或包括链路前缀的全球地址的PMIP地址），并通知其相同的MAG。 MAG用LMA（330）注册与多个地址相关的多个绑定。

摘要： Disclosed is a technique of, in a network conducting network based local mobility management, suppressing generation of signaling and an increase of processing load on a network entity and preventing a delay. According to this technique, a mobile node (MN 130) receives specific information (a token) including an interface identifier and a binding identifier, for example, from a network side (MAG 120) when connecting therewith first. When the mobile node conducts a handover, the mobile node notifies a next connecting MAG 122 of the token. The MAG receiving the token can judge based on this token whether the connection by the mobile node is due to a handover changing a connection point for a certain interface or due to a new connection using a different interface without making an inquiry to other network nodes.
摘要翻译：本发明公开了一种在进行基于网络的本地移动性管理的网络中抑制信令的产生和网络实体上的处理负荷的增加并防止延迟的技术。根据该技术，移动节点（MN 130）首先从网络侧（MAG 120）接收包括接口标识符和绑定标识符的特定信息（令牌）。当移动节点进行切换时，移动节点通知令牌的下一个连接MAG 122。接收令牌的MAG可以基于该令牌判断移动节点的连接是否由于切换改变特定接口的连接点，或者由于使用不同接口的新连接而不对其他网络节点进行查询。

摘要： A technique is disclosed, by which generation of redundant signaling caused by processing to establish route optimization can be suppressed. According to this technique, an overlay network is formed on a network, and an overlay network service of home agent is provided by a pHA (proxy home agent) 124. An MR (mobile router) 130 and a VMN (visiting mobile node) 140 connected to the mobile network are both subscribed in the overlay network service. In this case, when MR is going to perform optimization processing of a route to a home agent of VMN, pHA transmits change-HA messages 216 and 218 to notify VMN to change the home agent to the home agent of MR. When VMN changes the home agent to the home agent of MR, MR recognizes that processing of route optimization to the home agent of VMN is not needed.

摘要： The present invention provides a technique to prevent the generation of a large number of binding update messages in an overlay network when a mobile node changes connection points. According to this technique, in a communication system where a home agent HA 1210 for holding BCE (Binding Cache Entry) of a mobile node MN 1220 and a plurality of proxy home agents pHA 1212, pHA 1214 and pHA 1216 each capable to operate as a proxy of HA 1210 are overlaid on a global communication network 1200, and BCE of MN 1220 held by HA 1210 is delegated to pHA 1214 where MN 1220 is connected. Further, when MN 1220 is re-connected to pHA 1216 of move destination different from pHA 114 of move source, BCE of MN 1220 delegated to pHA 1214 of move source is re-delegated to pHA 1216 of move destination.

摘要： Disclosed is a technique whereby a tunnel entry point, which encapsulates a packet (generates a tunnel packet), can detect the presence of a tunneling loop causing a packet to loop the same path while encapsulated. According to this technique, upon receipt of a packet from a source node (source) 1100, TEP (tunnel entry point) 1120 inserts it into a tunnel packet header for encapsulation. Upon receipt of tunnel packets from TEP 1120 and TEP 1140, each of TEP 1140 and TEP 1160 copies the identifier of the original tunnel packet header to a new tunnel packet header for encapsulation. When this tunnel packet returns to TEP 1120 due to a tunneling loop, the tunneling loop is detected by referring to the identifier in the received tunnel packet.
摘要翻译：公开了一种技术，其中封装分组（生成隧道分组）的隧道入口点可以检测出存在引导分组在封装时循环相同路径的隧道循环。根据该技术，当从源节点（源）1100接收到分组时，TEP（隧道入口点）1120将其插入隧道分组报头以进行封装。在接收到来自TEP 1120和TEP 1140的隧道分组时，TEP 1140和TEP 1160中的每一个将原始隧道分组报头的标识符复制到新的隧道分组报头以进行封装。当该隧道报文由于隧道循环而返回给TEP 1120时，通过参考接收到的隧道报文中的标识符来检测隧道环路。
