摘要： Embodiments disclosed herein relate to methods and systems for grouping pilot signals and using such grouping for pilot strength reporting and set management in multi-carrier communication systems. In one embodiment, an access network may assign a group identifier (or “group ID”) to each of the pilot signals associated with the sector, e.g., based on the coverage areas of the pilot signals, and transmit the pilot signals with the corresponding group IDs. PN offset may be used as the group ID. An access terminal may group the pilot signals received into one or more pilot groups in accordance with their group IDs, and select a representative pilot signals from each pilot group for pilot strength reporting. The access terminal may also use the pilot grouping to perform effective set management.

摘要： 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.
摘要翻译：这里描述了用于有效利用网络的回程资源的方法，用于在不牺牲延迟性能的情况下将寻呼数据传送到接入终端（AT）。可以基于诸如AT的位置，AT使用的应用以及AT的最近的活动级别等因素自适应地改变缓冲AT的数据的位置。为了便于确定，AT可以配置一个或多个注册边界。 AT可以被配置为具有小的注册半径，使得如果AT不移动到小注册半径之外，则可以将数据直接传送到AT的数据连接点。如果AT移动到小注册半径之外，则注册半径可以切换到大的注册半径，而接入网关可以代替本地缓冲AT的数据。

摘要： Access control for an access point (e.g., a cell of the access point) may be based on an access mode associated with the access point. For example, depending on the access mode, access control may involve performing a membership check for the access point. Such a membership check may be performed at a network entity, a source access point, or some other suitable location in a network. In some aspects, access control may involve performing a membership check for an access point in conjunction with a context fetch procedure. Such a procedure may be performed, for example, when an access terminal arrives at the access point after experiencing RLF at another access point.

摘要： Providing for establishment of local Internet Protocol access (LIPA) for cellular communication is provided herein. According to particular aspects of the subject disclosure, provided are mechanisms to identify a request to establish a packet network connection as a request for a LIPA context. Once identified, a local gateway associated with the UE or with a subscriber-deployed base station is identified, and a packet context is established to support LIPA traffic for the UE. Additional mechanisms support UE mobility from one base station to another, including identifying and terminating inactive LIPA contexts. Further, a UE is described that can recognize and facilitate the establishment of a LIPA context for applications executing at the UE.

摘要： Aspects describe separate caches that can be utilized to retain overhead information while device is in idle mode. A first cache can be associated with a first timer and can be utilized when a device is performing idle handoff. A second cache, associated with a second timer can be utilized when a device is not performing idle handoff. Second timer can have a longer period of validity than first timer. The separate caches can be utilized in networks that include femto cell topography, wherein re-use of pilot PN codes are at a greater frequency than the re-use frequency in macro cell topography.

摘要： 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.
摘要翻译：本公开涉及用于在用于WCD的接入网络之间的硬切换期间通过基于数据的通信网络来维持与无线通信设备（WCD）的最小服务质量（QoS）通信会话的技术。更具体地，该技术确定在最小QoS通信会话期间WCD和第一接入网络之间的闭合连接是否是由于第一接入网络和第二接入网络之间的硬切换。在硬切换的情况下，技术保持与包括在最小QoS通信会话中的数据流相关联的预定时间段的开放QoS保留，以使得能够在WCD和第二接入网络之间建立新连接。当在演进数据优化（EVDO）通信网络上执行通过因特网协议（VoIP）呼叫的语音呼叫时，本文描述的技术尤其有用。
