    • Ambiguity (e.g., confusion) associated with access point identifiers may be resolved by querying candidate target access points and/or by using historical records indicative of one or more access points that the access point has previously accessed. For example, messages may be sent to access points that are assigned the same identifier to cause the access points to monitor for a signal from an access terminal that received the identifier from a target access point. The target access point may then be identified based on any responses that indicate that a signal was received from the access terminal. In some aspects the access points subject to being queried may be selected using a tiered priority. In addition, it may be determined based on prior handoffs of a given access terminal that when that access terminal reports a given identifier, the access terminal usually ends up being handed-off to a particular access point. Accordingly, a mapping may be maintained for that access terminal that maps the identifier to that access point so that the mapping may be used to resolve any future confusion associated with the use of that identifier by that access terminal.
    • 可以通过查询候选目标接入点和/或通过使用指示接入点先前已经接入的一个或多个接入点的历史记录来解决与接入点标识符相关联的歧义(例如混淆)。 例如,可以将消息发送到被分配相同标识符的接入点,以使接入点监视来自接收来自目标接入点的标识符的接入终端的信号。 然后可以基于指示从接入终端接收到信号的任何响应来识别目标接入点。 在一些方面,可以使用分层优先级来选择要被查询的接入点。 另外,可以基于给定接入终端的在先切换来确定,当该接入终端报告给定的标识符时,接入终端通常结束被切换到特定接入点。 因此,可以为将该标识符映射到该接入点的该接入终端保持映射,使得该映射可以用于解决与该接入终端使用该标识符相关的任何未来混淆。

    • Apparatus and methods of hand-in of a call from a macro node to a femto node include receiving, at a target interface to a plurality of access points, a handoff request to handoff a call of a mobile station, wherein the handoff request comprises a cellular identifier corresponding to a pilot identifier of a pilot signal. Further, the apparatus and methods include determining that the plurality of access points share the cell identifier, and forwarding the handoff request to the plurality of access points that share the cell identifier. Additionally, the apparatus and methods include generating a handoff request acknowledgement comprising a pre-reserved resource that is common to the plurality of access points, wherein the pre-reserved resource enables the mobile station to communicate with the plurality of access points, and transmitting the handoff request acknowledgement to initiate the hand-in to one of the plurality of access points.

    • Seamless communication handoff is achieved by establishing a protocol tunnel to route leftover packets between network access nodes during the handoff. For example, in a mobile IP-based system, a mobile node may perform a handoff from a first access node that is associated with a first routing node to a second access node that is associated with a second routing node. To prevent the loss of any packets that may be in route for delivery to or from the first routing node during the handoff, the mobile node establishes a protocol tunnel with the first access node via the second access node. On the forward-link, packets being delivered from the first routing node are routed over the protocol tunnel to the second access node and then to the mobile node. On the reverse-link, packets being sent to the first routing node are routed over the protocol tunnel from the mobile node to the second access node and then to the first routing node. In conjunction with these operations, the mobile node concurrently maintains separate IP interfaces for the routing nodes. In addition, steps are taken to ensure that packets are routed to the appropriate IP interface during the handoff.
    • 无缝通信切换是通过建立协议隧道来实现的,该协议隧道在切换过程中在网络接入节点之间路由剩余分组。 例如,在基于移动IP的系统中,移动节点可以执行从与第一路由节点相关联的第一接入节点到与第二路由节点相关联的第二接入节点的切换。 为了防止在切换期间传输到或来自第一路由节点的路由中的任何分组的丢失,移动节点经由第二接入节点与第一接入节点建立协议隧道。 在前向链路上,从第一路由节点递送的分组通过协议隧道路由到第二接入节点,然后传送到移动节点。 在反向链路上,发送到第一路由节点的数据包通过协议隧道从移动节点路由到第二接入节点,然后被路由到第一路由节点。 结合这些操作,移动节点同时为路由节点维护单独的IP接口。 此外,采取步骤确保在切换期间将数据包路由到相应的IP接口。
