Abstract: Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described. Various features are directed to a mobile node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff. Other features of the invention are directed to the use of a core network node to store state information. State information stored in the core node can be accessed and used by access nodes in cases where a mobile node does not send a state transfer message during a handoff, e.g., because communication with the first access node is lost or because such messages are not supported.

Abstract translation: 描述用于存储，操纵，检索和转发用于支持与一个或多个终端节点（例如，移动设备）的通信会话的状态（例如，上下文和其他信息）的方法和装置。 各种特征涉及在切换操作期间控制从第一接入节点到第二接入节点的状态传输的移动节点，从而消除在切换期间在第二接入节点和第一接入节点之间传输的状态转移消息的任何需要 。 本发明的其它特征涉及使用核心网络节点来存储状态信息。 存储在核心节点中的状态信息可以在移动节点在切换期间不发送状态转移消息的情况下由接入节点访问和使用，例如，因为与第一接入节点的通信丢失或者因为不支持这样的消息 。
