摘要： Systems and methodologies are described that facilitate applying offsets and/or selectable hysteresis values to favor access points in cell reselection. In measuring and ranking surrounding access points in reselection, offsets can be applied to favorable access points to facilitate cell reselection thereto. The offset can positively affect measurements, and thus ranking as well, in some cases. Negative offsets can also be applied to lower measurements (and thus ranking) of some access points. Moreover, hysteresis values can be applied in measuring current cells to prevent frequent reselection. The hysteresis values can be selected based on a type of the current cell or related access point to expand the coverage area where desired. Thus, where the current access point is favorable, a larger hysteresis can be added to measurements related to the current access point.

摘要： Systems and methodologies are described that facilitate utilizing reselection indicators in reselecting access points in wireless communications. In particular, an indicator can be provided relating to a restricted association access point that specifies whether intra-frequency reselection is allowed. If so, a mobile device receiving the indicator can reselect to other access points, to which it has access, operating in a similar frequency. If not, the mobile device can evaluate access points in other frequencies so as not to cause substantial interference to the restricted association access point. In addition, a predicted level of interference caused by communicating with an intra-frequency access point can be computed and evaluated to override the reselection indicator, in some cases. Thus, a restricted association access point can control reselection for some devices to mitigate interference while allowing the devices to override prohibitive restricted access points.
摘要翻译：描述了有助于在无线通信中重新选择接入点中利用重选指示符的系统和方法。特别地，可以提供与指定是否允许频率内重选的限制关联接入点有关的指示符。如果是这样，则接收指示符的移动设备可以重新选择其具有访问权的其他接入点，以类似的频率操作。如果不是，移动设备可以评估其他频率的接入点，以免对受限关联接入点造成实质性的干扰。此外，在一些情况下，可以计算和评估由与频率内接入点通信引起的干扰的预测水平以覆盖重选指示符。因此，限制关联接入点可以控制一些设备的重选以减轻干扰，同时允许设备覆盖禁止限制的接入点。

摘要： The number of handover-related failures that occur in a communication system may be reduced by taking target access point conditions into account when declaring radio link failure and/or by delaying certain handover operations. In some aspects, criteria for radio link failure detection and access terminal-controlled mobility may take into account access point parameters related to neighboring cells that may be available as mobility targets. For example, filtering mechanisms for detecting radio link failure based on radio layer problem reports may also take into account the availability of various neighbor access points and their measured signal strengths. In addition, a handover command may be sent earlier than in conventional systems (e.g., the handover command may be sent even though the target access point is weaker than the source access point) and include an indication that instructs the access terminal to delay handover until a specified condition is met. For example, handover may be delayed until the target access point becomes stronger than the source access point.

摘要： Apparatus and methods for determining a location estimate of a mobile device based on an extended set of assistance data are presented. The extended assistance data includes assistance data for base stations, such as cellular base stations and access points, not expected to be viewable by the mobile device in a (current) first geographical area but expected to be viewable by the mobile device in a (future) second geographical area. By seeding the mobile device with assistance data expected to be useful in the future, the network reduces messaging between the network and mobile device and battery consumption by the mobile device.

摘要： Systems and methodologies are described herein that facilitate improved cell search and selection in a wireless communication system. For example, a terminal as described herein can utilize one or more Closed Subscriber Group (CSG)-specific offset and/or hysteresis parameters as described herein to increase the amount of time on which the terminal is allowed to camp on a desirable cell. Additionally, specialized reselection timing can be employed as described herein to increase a delay associated with selecting a Home Node B (HNB) or Home Evolved Node B (HeNB) cell, thereby reducing power consumption associated with rapid cell reselection operations in a densely populated network environment. Further, a two-step reselection process can be performed as described herein in the context of selecting a frequency for cell reselection, thereby mitigating the effects of rapid reselection between cells and/or frequencies due to CSG cell prioritization.
