Abstract: Methods and apparatus for controlling transmission of a base station, such as a Femto cell, based on the determined quality of a backhaul connection to a network are disclosed. In particular, a quality of a backhaul connection of a base station to a node in a communication network is determined. Based on this quality determination, transmission from the base station is either limited or stopped when the determined quality fails to meet a predefined condition. The degradation in quality of the backhaul connection, for example, affects the ability of the base station to offer sufficient service to access terminals. By limiting or stopping wireless transmission of the base station when the backhaul quality is degraded, access terminals either currently accessing the base station or attempting to connect to the base station can then more efficaciously hand off to another base station or access point.

Abstract: 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.

Abstract: Systems and methodologies are described that facilitate indicating global cell identifier (GCI) reporting in wireless communication to mitigate confusion caused by physical cell identifier (PCI) reporting in heterogeneous deployments. In particular, mobile devices can report GCI of access points to disparate access points to facilitate communication therebetween, such as during handover. Mobile devices can indicate GCI reporting during a system access request by selecting an access sequence corresponding to subsequent GCI reporting. Based on the access sequence, an access point can grant additional resources to receive the GCI, and the mobile device can communicate GCI over the resources. Using the GCI, the access point can communicate with a disparate access point related to the GCI.

Abstract: 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.
Abstract translation: 基于获取的信息配置接入点。 可以基于至少一个其他接入点的配置来配置接入点。 可以基于由至少一个其他接入点发送的标识符来选择要由接入点发送的标识符。 接入点可以在配置服务器的帮助下自行配置。 例如，接入点可以将诸如接入点的位置的信息发送到配置服务器，并且配置服务器可以响应该接入点的相邻接入点的列表。 配置服务器可以基于接入点的位置向接入点提供配置信息。 配置服务器还可以将接入点定向到不同的配置服务器。

Abstract: 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.
Abstract translation: 描述了有助于应用偏移和/或可选滞后值以有利于小区重选中的接入点的系统和方法。 在重选中测量和排列周围接入点时，可以将偏移量应用于有利的接入点，以促进小区重新选择。 在某些情况下，偏移可以积极地影响测量，并因此排列。 负偏移也可以应用于某些接入点的较低测量（并因此排序）。 此外，滞后值可用于测量电流单元，以防频繁重新选择。 滞后值可以根据当前单元格或相关接入点的类型进行选择，以扩大覆盖范围。 因此，当前接入点是有利的，可以将更大的滞后加到与当前接入点相关的测量中。

Abstract: Signaling-only access may be established with an access node under certain circumstances such as, for example, upon determining that a node is not authorized for data access at the access node. A node that is not authorized for data access at an access node may still be paged by the access node through the use of signaling-only access. In this way, transmissions by the access node may not interfere with the reception of pages at the node. A first node may be selected for providing paging while a second node is selected for access under certain circumstances such as, for example, upon determining that the second node provides more desirable service than the first node.

Abstract: Systems and methodologies are described that facilitate transmitting access point types and/or restricted association parameters using broadcast signals, such as beacons, pilot signals, and the like. The type or restricted association information can be indicated by one or more intrinsic aspects of the signal, such as specified parameters. In addition, the type or information can be indicated by one or more extrinsic signal aspects, such as frequency, interval, periodicity, and the like. Using this information, a mobile device can determine whether an access point implements restricted association. If so, the mobile device can request an access point or related group identifier before determining whether to establish connection therewith. The identifier can be verified against a list of accessible access points or groups to make the determination.

Abstract: Embodiments describe overlaying a broadcast multicast channel on top of a unicast network. Messages can be generated by protocols in a broadcast/multicast (BCMC) stack and tunneled through an IRTP of a serving access node. These messages can be transmitted on a BCMC channel and/or a unicast channel. Other messages can be generated by protocols in a unicast stack and tunneled to a B-IRTP of a BCMC Access node and transmitted on a BCMC channel to an access terminal.

Abstract: A set of wireless relay nodes are managed to facilitate inter-node routing of packets in the set. In some aspects, unique identifiers are defined for the wireless relay nodes to facilitate routing packets within the set. In some aspect a routing table is provided to each of the wireless relay nodes, wherein the routing table identifies each wireless relay node in the set and a next-hop entity for each of these wireless relay nodes. Each of the wireless relay nodes may then define a forwarding table based on the routing table.

Abstract: Systems and methodologies are described that facilitate communicating between access points using the same air interface as for serving wireless devices. Access points can communicate with one another over the air interface to exchange interference management messages related to negotiating and/or allocating resources among the access points or other messages. In addition, access points can prepare served wireless devices for time periods where the access points communicate with disparate access points over the air interface to mitigate confusion or radio link failure detection by the served wireless devices.
