摘要： Disclosed is a buffer management method for a mobile node in a mobile IP telecommunication network. The buffer management method supports a handoff of the mobile node from a first agent of a first network to a second agent of a second network. The method begins upon initiation of the handoff. A first message is sent to the first agent requesting the first agent to buffer any packets being sent to the mobile node. While the buffering is being performed, the handoff may be completed to the second agent. Once the handoff is complete, a second message can be sent to the first agent requesting the first agent to forward the buffered packets to the second agent.

摘要： In a mobile communication system having mobile foreign agents, the present invention eliminates the use of multiple source/destination headers attached to an information packet during the tunneling operation by using either a decapsulation/encapsulation or a forwarding operation with the encapsulated information packet. Either of these operations reduces the overhead incurred in the multiple encapsulation headers by reducing encapsulation of the information packet to a single level. Upon receipt of the information packet at the foreign agent on the communications system, the information packet is directed to the mobile node using a routing chain table maintained by the foreign agent or a next hop routing table maintained by the foreign agent and each mobile foreign agent in the transmission path. Once implemented, these data structures can also assist with routing of information packets within the foreign subnetwork.
摘要翻译：在具有移动外部代理的移动通信系统中，本发明通过使用封装/封装或转发操作与封装的信息分组来消除在隧道操作期间附加到信息分组的多个源/目的地报头的使用。这些操作之一通过将信息分组的封装减少到单个级别来减少在多个封装头部中产生的开销。在通信系统上的外部代理接收到信息分组时，信息分组被引导到移动节点由外部代理维护的路由链表或由外部代理和传输路径中的每个移动外部代理维护的下一跳路由表。一旦实现，这些数据结构也可以帮助外部子网内信息分组的路由。

摘要： The present invention supports a generalized link-layer address extension for an information packet transmission on an IP mobility system. In the invention, a link-layer address for a node can be communicated in any information packet rather than confined to a specialized message format. The link-layer address can be used in link-layer routing protocols to simplify mobile IP hand-offs and routing, reducing overhead data traffic and allowing more efficient use of network resources.

摘要： A new extensions structure for mobile IP control message extensions is employed to conserve the type field. Certain types of extensions, such as network access identifiers, are initially aggregated and subtypes are employed to identify the precise content of the extension (e.g., mobile node network access identifier, home agent network access identifier, foreign agent network access identifier, etc.). Long and short formats for the new extension structure are defined, with the long format applicable to nonskippable extensions carrying more than 256 bytes and the short format backwards compatible with currently defined skippable extensions with less than 256 bytes of data. This will greatly reduce usage of the type field.
摘要翻译：采用移动IP控制消息扩展的新扩展结构来节省类型字段。最初聚合某些类型的扩展，例如网络访问标识符，并且使用子类型来标识扩展的精确内容（例如，移动节点网络接入标识符，归属代理网络接入标识符，外部代理网络接入标识符等）。定义了新的扩展结构的长格式和短格式，长格式适用于携带多于256字节的不可扩展扩展，而短格式向后兼容于具有少于256字节数据的当前定义的可跳过扩展。这将大大减少类型字段的使用。

摘要： An improved wireless mobile IP system including an apparatus and method for managing transmission of information. Agent advertisements are used to detect movement of the mobile node and derive care-of addressing information for the Home Agent. Foreign Agents and Home Agents currently periodically broadcast an agent advertisement on the data channel. The claimed system reduces the need for agent advertisements by detecting movement of a mobile user into a new network using either the mobile node or a routine on a low-level protocol layer. After detection of movement, an agent solicitation message is transmitted from the mobile node or from the cell-site transmitter. The mobility agent then transmits a single agent advertisement in response. Derived care-of addressing information will then be registered with the Home Agent to support “tunneling” of communications to the mobile node through the foreign network. Transmission of agent advertisements and associated non-data traffic on the data channels will be reduced.
摘要翻译：一种改进的无线移动IP系统，包括用于管理信息传输的装置和方法。代理广告用于检测移动节点的移动并导出归属代理的转交寻址信息。外国代理和家庭代理商目前在数据频道上定期广播代理广告。所要求保护的系统通过使用移动节点或低级协议层上的例程来检测移动用户进入新网络的移动来减少代理广告的需要。在移动检测之后，从移动节点或小区现场发射机发送代理请求消息。移动代理然后响应地发送单个代理广告。然后将派生护理寻址信息注册到归属代理，以支持通过外部网络将通信“隧道化”到移动节点。数据通道上的代理广告和关联的非数据流量的传输将会减少。
