Abstract: Systems and methodologies are described that facilitate avoidance of duplicative resource allocation and/or erroneous service charges via unambiguously indicating an entity responsible for quality of service (QoS) initiation. In one example, an indication is provided to a mobile device to indicate a preference for network-initiated QoS or a preference for device-initiated QoS. QoS for a data flow can be established in accordance with the indication. For instance, the mobile device initiates QoS when the indication specifies a preference for device-initiated QoS while a network establishes QoS when the indication specifies a preference for network-initiated QoS.

Abstract: Systems and methodologies are described that facilitate identifying and/or selecting femto cells in a wireless communication environment. A mobile device can scan an Auxiliary Pilot Channel to detect auxiliary pilot channel information (e.g., a particular Walsh Code, . . . ) sent from a base station. Moreover, the identified auxiliary pilot channel information can be evaluated to detect a characteristic of the base station. For instance, the identified auxiliary pilot channel information can be compared with stored auxiliary pilot channel information (e.g., Walsh Code(s) included in a whitelist, blacklist, . . . ). Moreover, a Synchronization Channel can be read based upon the detected characteristic. Further, a Common Pilot Channel, for example, can be analyzed to search for pseudo-noise (PN) offset(s) reserved for femto cell base stations, and the scan of the Auxiliary Pilot Channel can be initiated in response to detecting at least one reserved PN offset.

Abstract: A system and method of crawling at least one website comprising at least one URL includes maintaining a lookup structure comprising all of the URLs known to be on a website; calculating a hub score for each webpage of the website to be recrawled, wherein the hub score measures how likely the to be recrawled webpage includes links to fresh content published on the website; sorting all the to be recrawled pages by their hub scores; and crawling the to be recrawled pages in order from highest hub scores to lowest hub scores. The calculating comprises computing a first value equaling a percentage of a number of new relative URLs on the to be recrawled page; computing a second value equaling a percentage of a previous hub score of the to be recrawled page; and computing the hub score as a sum of the first and the second values.

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 triggering multi-carrier requests at a mobile device and granting or denying the request at the access point. The mobile device can determine when to request additional carriers from the access point based on communication parameters, such as buffer levels, inflow/outflow data rates, PA headroom for handling an additional carrier, a timer for requesting the carrier, a maximum number of allocable carriers, and/or the like. Upon receiving the request, the access point can grant or deny the request based at least in part on subscriber level of the mobile device, available resources in the access point, reverse link throughput, and/or the like. Allocating additional carriers to the mobile device can increase throughput for communicating with the access point.

Abstract: Power savings may be achieved in a packet-switched system by grouping packets. For example, packets may be queued while a portion of the system is in a suspended state. In some embodiments, power savings are provided in a wireless system to increase talk time. Here, packets may be queued while one or more components such as a radio of the wireless device are in a suspended state.

Abstract: In a high-rate packet data (HRPD) wireless communication network, an Access Terminal (AT) selects its serving cell, and additionally provides an advance indication of a pending cell selection. Upon receipt of the advance indication, the network directs data packets destined for the AT to the indicated target cell, which queues the data. The target cell obtains a prediction of an amount of data that the currently serving, or source, cell may transmit to the AT between the advance indication and the cell selection. Following the cell selection, the target cell transmits data packets to the AT beginning at an offset into the transmission queue that corresponds to the predicted data amount. When the target cell receives the actual transmitted data amount from the source cell, it may make adjustments in data packet transmission to the AT to ameliorate the effects of any miss-prediction.

Abstract translation: 在高速率分组数据（HRPD）无线通信网络中，接入终端（AT）选择其服务小区，并另外提供待决小区选择的提前指示。 在接收到提前指示时，网络将指定给AT的数据分组指向指示的目标小区，该小区对数据进行排队。 目标小区获得在提前指示和小区选择之间当前服务或源小区可以向AT发送的数据量的预测。 在小区选择之后，目标小区从偏移开始向AT发送数据分组到与预测数据量对应的传输队列中。 当目标小区从源小区接收到实际发送的数据量时，可以对数据分组传输给AT进行调整，以改善任何缺失预测的影响。

Abstract: In a mobile communication network comprising a plurality of access nodes, session information for a communication session is stored in one access node and may be requested by a peer access node. A requesting access node determines the location of session information based on the mobile station identifier associated with the communication session. If the session information is transferred to the requesting node, the requesting node may allocate a new mobile station identifier to the mobile station for the communication session.
