摘要： AP's associated with a communication network and any wireless devices desiring contact, operated according to a protocol in which each wireless device selects AP's with which to communicate. A system coordinator causes the AP's to operate so as to guide each wireless device to an AP selected by the system coordinator. This has the effect that, notwithstanding that the protocol involves having the wireless device make the selection of AP, functionally, the AP's make the selection for it. In a 1st technique, multiple AP's share an identifier, with the system coordinator directing one particular AP to respond to the wireless device, thus appearing to wireless devices as a “personal cell”. In a 2nd technique, AP's each maintain identifiers substantially unique to each wireless device, with the system coordinator directing only one particular AP to maintain any particular wireless device's identifier, thus appearing to wireless devices as a “personal AP”.

摘要： A method and apparatus are described for supporting dynamic and distributed mobility management (DMM). A wireless transmit/receive unit (WTRU) may attach to a first distributed gateway (D-GW), and configure a first Internet protocol (IP) address based on a prefix locally provided by the first D-GW. The WTRU may move and attach to a second D-GW while carrying out an on-going communication session with a correspondent node (CN). The WTRU may configure a second IP address based on a prefix provided by the second D-GW. The WTRU may use the first IP address for carrying out the on-going session and use the second IP address for a new communication session.

摘要： Techniques are provided to enable support of roaming wireless devices in a network such that the wireless devices can keep their Internet Protocol (IP) addresses as they roam across mobility sub-domains. Traffic for a wireless device that roams is tunneled back to the access switch that serves the IP subnet which includes an IP address for the wireless device. Traffic is tunneled back to that access switch for the wireless device when the wireless device roams to another access switch which does not serve the IP subnet for the wireless device in the same mobility sub-domain and when the wireless device roams to a different mobility sub-domain, in which case the traffic is tunneled between tunneling endpoints in the respective mobility sub-domains.

摘要： A method of facilitating multihoming in the case of a mobile node possessing an Upper Layer Identifier belonging to a home network, where the mobile node is assigned a Global Mobility Management anchor within the home network and a Local Mobility Management anchor within a visited network. The method comprises allocating to the mobile node a primary SHIM6 proxy at said Global Mobility Management anchor, and at least one secondary SHIM6 proxy at said Local Mobility Management anchor. At said primary SHIM6 proxy, a SHIM6 context is established on behalf of the mobile node in respect of a peer node; and the established context is shared with said secondary SHIM6 proxy. Locator switching is then performed in respect of traffic exchanged between the mobile node and said peer node at one of said primary and secondary SHIM6 proxies.

摘要： The present invention relates to a method in which a mobile node having mobility performs handover in a mobile communication system, and more particularly, to a fast handover method and system using network-based localized mobility management. According to an exemplary embodiment of the present invention, in a network access process between a mobile node and a base station, the base station sends a message allowing network access to the mobile node and a link-up message to an access router. Then, the access router sends a location registration message, which includes a mobile node identifier, a target base station identifier, a localized mobility anchor identifier, and access permission flag information, to a localized mobility anchor (LMA), and receives an acknowledgement (Ack) message including network prefix information. Accordingly, when a router advertisement (RA) message is sent to the base station, the mobile node performs duplicate address detection (DAD). Accordingly, fast handover is performed to reduce packet loss and delay that occur when the mobile node moves between networks, thereby minimizing the packet loss and delay.
摘要翻译：本发明涉及具有移动性的移动节点在移动通信系统中执行切换的方法，更具体地说，涉及一种使用基于网络的本地化移动性管理的快速切换方法和系统。根据本发明的示例性实施例，在移动节点和基站之间的网络接入过程中，基站发送允许对移动节点进行网络接入的消息和到接入路由器的链路消息。然后，接入路由器向本地化移动锚（LMA）发送包括移动节点标识符，目标基站标识符，本地化移动锚定标识符和访问许可标志信息的位置登记消息，并且接收确认（ Ack）消息，包括网络前缀信息。因此，当向基站发送路由器通告（RA）消息时，移动节点执行重复地址检测（DAD）。因此，执行快速切换以减少当移动节点在网络之间移动时发生的分组丢失和延迟，从而最小化分组丢失和延迟。

摘要： A technique disclosed enables a node having a plurality of interfaces to conduct connection of the plurality of interfaces simultaneously in a communication network domain. A mobile node having a plurality of interfaces connects one of the interfaces with a MAG (mobile access gateway) 11a to take part in a NetLMM domain 18 using a NetLMM protocol, and a LMA (local mobility anchor) 13 includes association information with the MAG 11a registered therein. When the mobile node connects another interface with another MAG 11b, the LMA receives a registration request for association information of this mobile node with the MAG 11b, and makes an inquiry to the already registered MAG 11a as to whether link with the mobile node is still valid or not. If the link is valid, the LMA keeps association information of the mobile node with both of the MAGs 11a and 11b.

摘要： Mobility between access domains in an Internet Protocol (IP) network can be supported by introducing a so-called Mobility Manager (MM) that maintains a database of currently attached devices and their current access domain location. The mobility manager may then detect, for a device registered in the database, a change of access domain from a first access domain to a second access domain by monitoring connection maintenance signaling related to the considered device. The mobility manager should at least obtain an indication of such a change of access domain. In response to a detected change of access domain, the mobility manager arranges for a reconfiguration of the network to forward traffic destined to an IP address of the device in the first access domain to a new location in the second access domain. In this way, the mobility manager allows the device to keep its IP address when moving between access domains.
摘要翻译：可以通过引入维护当前连接的设备的数据库及其当前访问域位置的所谓的移动管理器（MM）来支持互联网协议（IP）网络中的接入域之间的移动性。然后，移动性管理器可以通过监视与所考虑的设备相关的连接维护信令来检测对于在数据库中注册的设备，从第一接入域到第二接入域的接入域的改变。移动管理员至少应该获得访问域这种更改的指示。响应于检测到的接入域的改变，移动性管理器布置网络的重新配置以将目的地为第一接入域中的设备的IP地址的流转发到第二接入域中的新位置。以这种方式，移动管理器允许设备在接入域之间移动时保持其IP地址。
