摘要： Paging load and/or registration load in a network is reduced by using different types of identifiers to specifying which nodes page an access terminal in the network. In some aspects, the network maintains a list that specifies that certain individual nodes (e.g., cells or sectors) are to page a given access terminal and/or that one or more zones (e.g., tracking areas) are to page the access terminal. In some aspects, an access terminal in a network may be configured to provide a forward-looking paging list to the network. The list provided by an access terminal may specify different types of node identifiers (e.g., individual node identifiers, subscriber groups, etc.). The network may then use the list to determine which nodes are to page a given access terminal such that when the access terminal moves to a different node, that node may already be configured to page the access terminal. In some aspect paging load and registration load are managed in a deployment that includes different types of access points. For example, access points of a first type (e.g., macro nodes) may provide service over relatively large coverage areas and access points of a second type (e.g., femto nodes) may provide service over smaller coverage areas and/or provide restricted service.

摘要： Systems and methodologies are described that facilitate utilizing restriction codes in rejecting connection requests with restricted association access points to indicate a reason for the rejection. Mobile devices can maintain a list of accessible access points and/or groups of access points, which can be consulted during cell reselection to ensure unsuitable restricted association access points are not utilized in cell reselection. Based on receiving a rejection code from a restricted association access point, a mobile device can remove the access point, or a related group, from its maintained list so that subsequent reselection attempts avoid the access point and/or access points in the related group.

摘要： Confusion resulting from assigning the same node identifier to multiple nodes is resolved through the use of confusion detection techniques and the use of unique identifiers for the nodes. In some aspects an access point and/or an access terminal may perform operations relating to detecting confusion and/or providing a unique identifier to resolve confusion.

摘要： Confusion resulting from assigning the same node identifier to multiple nodes is resolved through the use of confusion detection techniques and the use of unique identifiers for the nodes. In some aspects a network may provide a time gap (e.g., an asynchronous time gap) during which an access terminal may temporarily cease monitoring transmissions from a source node so that the access terminal may acquire a unique identifier from a target node. In some aspects an access terminal may commence handover operations at a target node after determining whether the access terminal is allowed to access the target node. In some aspects a source node may prepare several target nodes for potential handover in the event confusion is detected or likely. Here, the source node may send information relating to the preparation of the potential target nodes to the access terminal whereby the access terminal uses the handover preparation information to initiate a handover at that target node.

摘要翻译： 通过使用混淆检测技术和为节点使用唯一标识符来解决通过将相同的节点标识符分配给多个节点而产生的混淆。 在一些方面，网络可以提供时间间隔（例如，异步时间间隔），在此期间，接入终端可能暂时停止监视来自源节点的传输，使得接入终端可以从目标节点获取唯一的标识符。 在一些方面，接入终端可以在确定接入终端是否允许接入目标节点之后，在目标节点处开始切换操作。 在某些方面，在检测到或可能的混淆的情况下，源节点可以准备若干目标节点用于潜在的切换。 这里，源节点可以向接入终端发送与潜在目标节点的准备有关的信息，由此接入终端使用切换准备信息来发起该目标节点处的切换。

摘要： Handover parameter settings are automatically adapted in access points in a system to improve handover performance. Reactive detection techniques are employed for identifying different types of handover-related failures and adapting handover parameters based on this detection. Messaging schemes are also employed for providing handover-related information to access points. Proactive detection techniques also may be used for identifying conditions that may lead to handover-related failures and then adapting handover parameters in an attempt to prevent such handover-related failures. Ping-ponging may be mitigated by adapting handover parameters based on analysis of access terminal visited cell history acquired by access points in the system. In addition, configurable parameters (e.g., timer values) may be used to detect handover-related failures.

摘要： Information is maintained to assist in determining whether an access terminal is allowed to establish communication with an access point associated with a closed subscriber group (CSG). For example, CSG subscription information for visiting access terminals may be maintained at a local server. In this way, a network may use the locally stored CSG subscription information for a given access terminal to determine whether to allow that access terminal to access an access point in the network. In addition, multiple CSG lists may be maintained at an access terminal. For example, an access terminal may maintain a first list that is updateable by an operator and a second list that is updateable by a user. Here, the updating of one list may be based on a change in the other list.

摘要： An access point is configured based on acquired information. An access point may be configured based on the configuration(s) of at least one other access point. An identifier to be transmitted by an access point may be selected based on the identifier(s) transmitted by at least one other access point. An access point may configure itself with assistance from a configuration server. For example, the access point may send information such as the location of the access point to a configuration server and the configuration server may respond with a list of neighboring access points for that access point. A configuration server may provide configuration information to an access point based on the location of the access point. A configuration server also may direct an access point to a different configuration server.

摘要： Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a first station (e.g., a base station or a terminal) may receive a message sent by a second station to request reduction of interference on at least one resource. In response to receiving the message, the first station may determine a first transmit power level to use for the at least one resource based on one or more factors such as a priority metric sent in the message, the buffer size at the first station, etc. The first station may send a power decision pilot on the at least one resource at a second transmit power level determined based on the first transmit power level.

摘要： In-band provisioning enables subscribers to manually provision themselves via an access point at which the subscribers would not otherwise be allowed access. For example, a subscriber may be temporarily accepted by a restricted access point (e.g., an access point that belongs to a closed subscriber group). The subscriber is then given limited access to enable the subscriber to be provisioned at the access point. For example, the subscriber may be provisioned for full access at the access point if the subscriber presents a valid authorization credential to a provisioning entity.
