摘要： In a handover operation an access terminal is handed over from a source access point to a target access point. To facilitate efficient identification of a target access point, a handover operation may be initiated by the target access point. A candidate frequency search also may be invoked to confirm that an access terminal identified by a target access point for a handover is in the vicinity of the target access point. A source access point may verify whether an access terminal is in a vicinity of a target access point to determine whether to perform a handover operation. A source access point may handle potential ambiguity between several target access points by sending handover commands to each of these target access points. An access terminal also may assist in the determination of whether to perform a handover operation.

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.

摘要翻译： 在切换操作中，接入终端从源接入点切换到目标接入点。 为了便于目标接入点的有效识别，切换操作可以由目标接入点发起。 还可以调用候选频率搜索以确认由目标接入点识别的用于切换的接入终端在目标接入点附近。 源接入点可以验证接入终端是否在目标接入点附近，以确定是否执行切换操作。 源接入点可以通过向这些目标接入点中的每一个发送切换命令来处理几个目标接入点之间的潜在模糊性。 接入终端还可以协助确定是否执行切换操作。

摘要： Provisioning and access control for communication nodes involves assigning identifiers to sets of nodes where the identifiers may be used to control access to restricted access nodes that provide certain services only to certain defined sets of nodes. In some aspects provisioning a node may involve providing a unique identifier for sets of one or more nodes such as restricted access points and access terminals that are authorized to receive service from the restricted access points. Access control may be provided by operation of a restricted access point and/or a network node. In some aspects, provisioning a node involves providing a preferred roaming list for the node. In some aspects, a node may be provisioned with a preferred roaming list through the use of a bootstrap beacon.
