摘要： Local mobility within a subnet is supported by classifying wireless base stations, and the routers used to forward packets to those base stations, within defined domains. Domains are defined to incorporate a subnet having a plurality of base stations. Base stations are used by mobile devices to attach to the wired portion of a packet-based network, such as the Internet, and exchange packets thereover with a correspondent node. Packets sent from the correspondent node to the mobile device have a packet destination address corresponding to the mobile device. The mobile device retains this address for the duration of time it is powered up and attached to the Internet via any base station within a given domain. Host-based routing is utilized to update routing table entries corresponding to the mobile device at routers incorporated within a single domain. The routing table entries are established and updated via path setup schemes to convey packets destined for the mobile device along the proper established path through the domain routers and base stations, regardless of the domain base station through which the mobile device is attached. Path setup schemes utilize power up, refresh, and handoff path setup messages to maintain the proper relationship between router interfaces and packet addresses for routing table entries.

摘要： The number of packet routing addresses utilized within a wired subnet offering wireless services via subnet base stations is reduced by assigning a packet routing address to a wireless device accessing a wired subnet upon power up of the wireless device. A Dynamic Host Configuration Protocol (DHCP) server is utilized to assign the packet routing addresses, and supplies addresses either directly or indirectly via a node acting as a DHCP relay for a DHCP server. If the assigned packet routing address is a care-of address for a foreign domain, the address is released upon wireless device power down or upon handoff of the wireless device to a new domain. If the assigned packet routing address is an address for the wireless device within a home domain, the address is released upon wireless device power down.
摘要翻译：通过在无线设备上电时向无线设备访问有线子网分配分组路由地址来减少通过子网基站提供无线服务的有线子网内所使用的分组路由地址的数量。使用动态主机配置协议（DHCP）服务器来分配分组路由地址，并且通过作为DHCP服务器的DHCP中继的节点直接或间接地提供地址。如果分配的分组路由地址是外部域的转交地址，则在无线设备断电或无线设备切换到新域时释放该地址。如果所分配的分组路由地址是归属域内的无线设备的地址，则在无线设备断电时释放该地址。

摘要： A tunneling optimization is described in which packets are forwarded from a home agent to a mobile device by co-locating a foreign agent corresponding to a mobile device at the mobile device. When a mobile device acquires a new foreign agent, the mobile device notifies the home agent as to the corresponding foreign agent address. A packet received at the home agent having the mobile device as a packet header destination address is parsed and the foreign agent address is substituted for the mobile device address, and the packet is forwarded to the foreign agent. The foreign agent, upon receiving the packet, removes the foreign agent address and replaces the mobile device address as the packet header destination address. The packet is then forwarded to the mobile device.

摘要： Base stations on an Internet protocol (IP) network define a number of paging areas. An IP mobile host assumes one of (i) an active state, wherein the host informs other network nodes of a change in its point of attachment from one base station to another, and (ii) a standby state wherein the host informs other nodes only when a new point of attachment is a base station of a different paging area from a last point of attachment, thus conserving power at the mobile host. When data on the network is addressed to a standby mobile host, a page request is directed to a base station(s) in the host's current paging area for transmission. The host enters the active state and transmits a page response which is received by a base station in the current paging area, and network routing information for the host is updated accordingly.

摘要： Domains are defined to incorporate a subnet including a plurality of base stations and routers. Base stations are used by mobile devices to attach to the wired portion of a packet-based network, such as the Internet, and exchange packets thereover with a correspondent node. Local mobility between domain base stations is provided by including and updating routing table entries at domain routers and base stations for forwarding packets having a mobile device's address as a destination address to the mobile device. Packets are delivered to the mobile device regardless of the domain base station to which the mobile device is attached. When a mobile device is attached to a base station included within a foreign domain, a care-of address is assigned, and packets are tunneled for delivery of packets to the mobile device. Only one care-of address is required per mobile device per foreign domain. Routing table entries used for packet delivery are updated on a purely local subnet basis within domains, whether home domain or foreign domain, making handoffs between base stations substantially transparent to the home agent and the correspondent node.
