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: Transmission by a first node may be controlled based on a status of a second node. The status of the second node may indicate, for example, whether the second node will be communicating with the first node. Thus, if it is determined based on the status of the second node that the second node may not be communicating with the first node, transmissions by the first node may be temporarily disabled until there is a change in status, and vice versa.

Abstract translation: 可以基于第二节点的状态来控制第一节点的传输。 第二节点的状态例如可以指示第二节点是否将与第一节点进行通信。 因此，如果基于第二节点的状态确定第二节点可能不与第一节点通信，则第一节点的传输可以被暂时禁用，直到状态发生变化，反之亦然。

Abstract: Methods, system and computer readable medium for detecting duplicate content in a pair of media files prior to publication on a webpage include generating fingerprints for the contents of each of the pair of media files. The fingerprints of one of the pair of media file are then compared with the fingerprints of another of the pair of media files to compute a similarity score. The similarity score is compared against an established threshold. If the similarity score exceeds the established threshold, it is determined that the two media files are substantial duplicate of one another.

Abstract: Disclosed is a method of retrieving constant values. The method comprises compiling key-value pairs into a unified regular expression, evaluating the unified regular expression against a transformed input string to match a particular key and extracting the constant value associated with that particular key. The input string in transformed by linking different tags associated with each key-value pair in the unified regular expression into a single linked tag and linking the single linked tag to the input string. Additionally, the method provides for associating the constant value in each key-value pair with an un-fixed key (i.e., a unique regular expression) as opposed to a fixed key, so that different input strings can be matched to the same key.

Abstract: An access terminal scans for nearby access points and maintains a candidate list of access point with which the access terminal may associate in the event the access terminal's communication with its current access point deteriorates for some reason. This search procedure may be performed in a proactive manner whereby the access terminal repeatedly performs scans and updates its list of candidate access points when it is powered on. In some aspects, the search procedure used by the access terminal may be based on a state of the wireless device. In addition, different states of the access terminal may be associated with different optimization criteria.

Abstract: The quality of a broadcast stream is varied responsive to changes in the utilization of forward link air interface resources. The network monitors utilization of forward link air interface resources and dynamically changes the forward link air interface resources dedicated to the broadcast stream responsive to changes in the utilization of forward link air interface resources. The quality of the broadcast stream is scaled to the allocated forward link resources. The broadcast stream may include a layered content and scaling can be achieved by varying the number of layers transmitted over the air interface. The network may notify mobile stations in advance when changes in the quality of the broadcast will take place. When the broadcast stream originates with a mobile station, the forward link air interface resources may be limited by the quality of the broadcast stream transmitted over a reverse link channel from the originating mobile station.

Abstract: A mobile communication network includes a plurality of access nodes that can serve different roles in support of a communication session with a mobile station. An access node can serve as a connecting node that receives access requests the mobile station, as an anchor node to anchor a radio packet connection with a core network for the communication session; or as a primary node to store session information for the communication session. When the communication session is established, the anchor node for the communication session may select another access node to serve as the primary node. Session information can be stored at both the anchor node and primary node so that data can be delivered to the mobile station if either one of the anchor node and primary node are available. During a communication session, a connecting node receiving a connection request from a dormant mobile station may request session information from the primary node. The radio packet connection may also be moved to the connecting node.

Abstract: In a multicarrier CDMA system, a data stream is divided into two or more substreams and each substream is assigned to a different carrier. An RLP context is created for each carrier and the substreams are transmitted within a corresponding RLP context over a designated carrier. If a carrier is lost or dropped, the corresponding RLP context can persist after loss of the carrier and retransmitted packets tunneled to a different carrier.

Abstract: A hybrid test bed mixes simulated and actual wireless communication network entities in a real-time packet data simulation. In at least one embodiment, the test bed supports end-to-end simulation for a packet data application running on a mobile station simulator. The test bed provides a realistic assessment of that application's real-time performance by constraining packet data transmissions from a radio base station simulator to the mobile station simulator according to peak data throughput estimates and mobility event processing determined from a detailed wireless communication network simulation. Additionally, the test bed includes or is associated with a graphical display system providing real-time performance information.

Abstract: Two or more different sets of access parameters are stored in mobile station memory. When the mobile station sends an access message on the reverse access channel, it selects a set of access parameters based on the type of service. For high priority services, the mobile station selects a set of access parameters that reduces call setup latency. The network can change a selected set of access parameters by sending an access parameter message containing the updated parameter values. The access parameter message includes a priority field indicating the selected set of access parameters to be updated.
