Abstract: 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.

Abstract translation: 无缝通信切换是通过在切换期间建立协议隧道来在网络接入节点之间路由剩余分组来实现的。 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。 为了防止在越区切换期间可能在路由中传递到第一路由节点或从第一路由节点传递的任何分组的丢失，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，从第一路由节点传递的分组通过协议隧道路由到第二接入节点，然后路由到移动节点。 在反向链路上，发送到第一路由节点的分组通过协议隧道从移动节点路由到第二接入节点，然后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，还采取措施确保在越区切换期间将数据包路由到适当的IP接口。

Abstract: Described herein is methodologies for efficient utilization of backhaul resources of a network for delivering paging data to an access terminal (AT) without sacrificing delay performance. A location that buffers data for an AT can be adaptively changed based on factors such as the location of the AT, applications utilized by the AT, and a recent activity level of the AT. To facilitate this determination, an AT can be configured with one or more registration boundaries. An AT can be configured with a small registration radius such that if the AT does not move outside of the small registration radius, data can be delivered directly to a data attachment point for the AT. If the AT moves outside of the small registration radius, the registration radius can be switched to a large registration radius and the access gateway can instead locally buffer data for the AT.

Abstract translation: 这里描述的是用于有效利用网络的回程资源以将寻呼数据传送到接入终端（AT）而不牺牲延迟性能的方法。 缓冲AT的数据的位置可以基于诸如AT的位置，AT使用的应用以及AT的最近活动水平等因素而自适应地改变。 为了便于确定，AT可以配置一个或多个注册边界。 AT可以配置一个小的注册半径，这样如果AT不移出小的注册半径，数据可以直接传送到AT的数据连接点。 如果AT移动到小的注册半径之外，则注册半径可以切换到较大的注册半径，并且接入网关可以在本地缓存AT的数据。

Abstract: Methods and apparatuses are provided that facilitate routing of messages of a positioning protocol, such as long term evolution (LTE) positioning protocol annex (LPPa). A positioning server can determine a network area identifier of one or more messages based at least in part on an identifier of a base station associated with the one or more messages. Based at least in part on the network area identifier, the positioning server can provide the one or more messages to an intermediate network node corresponding to the one or more base stations, such as a mobility management entity (MME). MME can similarly provide the one or more messages to an optional gateway between it and the one or more base stations based at least in part on receiving the network area identifier in the one or more messages. In addition, a base station can update positioning information with the positioning server.

Abstract: Aspects are disclosed for facilitating a timing alignment in a multicarrier system. In one aspect, at least one downlink timing associated with at least one downlink carrier is determined, and an uplink timing associated with an uplink group of carriers is ascertained based on at least one downlink timing and a timing offset associated with the uplink group of carriers. Each of the uplink group of carriers is then transmitted within a threshold value of the uplink timing. In another aspect, a downlink communication is transmitted to a wireless terminal via at least one downlink carrier. This embodiment further includes assigning a timing offset to an uplink group of carriers, and providing the timing offset to the wireless terminal via the at least one downlink carrier. An uplink communication is then received via the uplink group of carriers according to the timing offset.

Abstract: The disclosure relates to techniques for maintaining minimum quality of service (QoS) communication sessions with a wireless communication device (WCD) over a data-based communication network during a hard handoff between access networks for the WCD. More specifically, the techniques determine whether a closed connection between the WCD and a first access network during a minimum QoS communication session is due to a hard handoff between the first access network and a second access network. In the case of a hard handoff, the techniques maintain open QoS reservations associated with data flows included in the minimum QoS communication session for a predetermined period of time to enable a new connection to be established between the WCD and a second access network. The techniques described herein may especially useful when performing a voice over Internet Protocol (VoIP) call over an Evolution - Data Optimized (EVDO) communication network.
