摘要： Local breakout is provided by one or more nodes (e.g., a local access point and/or a local gateway) in a wireless network to facilitate access to one or more local services. In conjunction with local breakout, multiple IP points of presence relating to different levels of service may be provided for an access point. For example, one point of presence may relate to a local service while another point of presence may relate to a core network service.

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： Various methods, apparatuses and articles of manufacture may be implemented for use in one or more computing platforms to adaptively provide and/or obtain indoor navigation assistance data (INAD) update(s) for use by a mobile device. An INAD update may, for example, comprise a subset of INAD available for an indoor environment. Such a subset may be determined based, at least in part, on a bounded region in an electronic map of the indoor environment. Such a bounded region may, for example, have a shape and/or a size based, at least in part, on at least one parameter indicative of a motion state of the mobile device.

摘要： An adaptive scheme controls the transmission of interference management messages by wireless nodes. For example, the adaptive scheme may be used to determine whether and/or how to transmit resource utilization messages. Such a determination may be based on, for example, comparison of a quality of service threshold with a current quality of service level associated with received data. A quality of service threshold may be adapted based on the effect of previously transmitted resource utilization messages. A quality of service threshold for a given wireless node may be adapted based on the frequency at which the wireless node transmits resource utilization messages. A quality of service threshold for a given wireless node may be adapted based on information received from another wireless node. An adaptation scheme also may depend on the type of traffic received by a given wireless node. A quality of service threshold also may be adapted based on throughput information.

摘要： Disclosed are methods, apparatus, computer readable media and other implementations, including a method for communicating network information. The method includes transmitting a request message from a mobile device to an access point, and receiving, at the mobile device, a reply message transmitted from the access point in response to receiving the request message, the reply message including data representative of a transmitted signal power level at the access point of the reply message. The method further includes determining, based on the received reply message including the data representative of the transmitted signal power level at the access point, a received signal power level at the mobile device of the reply message, and a round trip time from a first time instance when the request message was transmitted from the mobile device to a second time instance when the reply message was received at the mobile device.

摘要： Local IP access is provided in a wireless network to facilitate access to one or more local services. In some implementations, different IP interfaces are used for accessing different services (e.g., local services and operator network services). A list that maps packet destinations to IP interfaces may be employed to determine which IP interface is to be used for sending a given packet. In some implementations an access point provides a proxy function (e.g., a proxy ARP function) for an access terminal. In some implementations an access point provides an agent function (e.g., a DHCP function) for an access terminal. NAT operations may be performed at an access point to enable the access terminal to access local services. In some aspects, an access point may determine whether to send a packet from an access terminal via a protocol tunnel based on the destination of the packet.

摘要： Systems and methodologies are described that facilitate establishing synchronization and/or mitigating interference with a time division duplexing (TDD) access point base station in a wireless communication environment. For example, a TDD configuration can be selected for the access point base station based upon received information to control interference. By way of another example, the access point base station can be synchronized with a disparate base station based upon the received information. Moreover, the received information can relate to the disparate base station, a served user equipment (UE) (e.g., served by the access point base station, . . . ), and/or a non-served UE (e.g., served by a base station other than the access point base station, . . . ). For example, the served UE can transmit a measurement related to the disparate base station to the access point base station.
