摘要： A network communication entity (e.g., an access terminal, access network and/or application server) obtains a location associated with a given access terminal that is attempting to participate in a given communication service, obtains a priority level of the given access terminal, determines a given level of service restriction for the given access terminal's participation in the given communication service based on the obtained location and the obtained priority level and restricts the given access terminal's participation in the given communication service based on the given level of service restriction. In an example, the priority levels can be established such that low-priority access terminals obtain a first level of service restriction within a defined location region, and a second level of service restriction outside of the defined location region, whereas high-priority access terminals obtain the first level of service restriction both inside and outside of the defined location region.

摘要： Aspects of reducing an occurrence of false grants for a multicast session within a wireless communications network are disclosed. For example, an access network receives an announce message to be transmitted to a plurality of access terminals, the received announce message configured to announce a given multicast session. The access network determines whether sufficient resources are available to support the given multicast session, The access network configures the received announce message to convey whether sufficient resources are available to support the given multicast session based on the determining step, and transmits the configured announce message to the plurality of access terminals. A given access terminal receives the announce message, and determines whether the received announce message indicates whether sufficient resources are available to support the given multicast session. The given access terminal sends an announce acknowledgment (ACK) message that indicates an acceptance or rejection of the given multicast session.

摘要： Embodiments are directed to an application-layer handoff of an access terminal from a first system of an access network to a second system of the access network during a communication session within a wireless communications system. In an embodiment, the access terminal sets up a communication session on the first system. A multimedia client measures application-layer performance parameters for the communication session supported by the first system, and determines whether to handoff the communication session to a second system based at least in part on the application-layer performance parameters. If the multimedia client determines to handoff the communication session to the second system, the multimedia client initiates the handoff and the communication session is transitioned to the second system.

摘要： Methods of supporting a multicast session within a wireless communications network are provided. An access terminal adjusts a monitoring rate of a downlink control channel either (i) after transmitting a multicast registration message in a sector that is not supporting a given multicast session or (ii) after receiving an announce message announcing the given multicast session. An access network anticipates the monitoring rate adjustment, and sends a message advertising the given multicast session (e.g., a broadcast overhead message (BOM)) based on the adjusted monitoring rate. Further, the announce message sent by the access network can be sent on the downlink control channel, and can be sent based on expected paging cycles, or monitoring rates, of the downlink control channel at one or more access terminals within the network prior to the monitoring rate adjustment.

摘要： Techniques and systems are disclosed for estimating an unknown image from a plurality of cone-beam computed tomography (CBCT) image projections. The unknown image is estimated by solving for minima of an expression comprising a fidelity term that is a function of the plurality of image projections and a regularization term that is responsive to a sparsity of the CBCT image projections. The minima of the expression is iteratively estimated by calculating an image gradient of the function, determining a step size based on a based on a Barzilai-Borwein (BB) formulation and adjusting the minima estimate using the projected image gradient and a step size.

摘要： An embodiment is directed to an access network that configures set of paging indicator (PI) bits within a quick paging channel (QPCH) cycle to page a group of access terminals. An access terminal within the group receives the QPCH cycle, and evaluates the PI bits to determine whether a unicast page and/or group page is present. Another embodiment is directed to selecting less than all timeslots in one or more control channel cycles of a downlink control channel, and configuring a page message to convey the selected timeslots to an access terminal. The access terminal receives the configured page message and decodes information only within the selected timeslots. Another embodiment is directed to generating a transport-layer message for transmission to at least one access terminal, and configuring the transport-layer message by modifying an application-layer portion of the transport-layer message. An access terminal receives the message and extracts the application-layer portion.

摘要： A mobile device provides first information to an access point over an out-of-band wireless link. The access point uses the first information to coarsely synchronize with a macrocell base station. The access point transmits a low power pilot signal that is formed using a pseudo-random noise (PN) sequence. The mobile device uses the out-of-band wireless link to provide second information to the access point that indicates a PN phase of the pilot signal with respect to a reference time point. The access point uses the second information to finely synchronize with the macrocell base station. The mobile device communicates with a mobile operator core network through the access point using an in-band wireless link to the access point. The mobile device compensates for propagation delay when obtaining time information. The mobile device provides additional information to the access point, which the access point uses to adjust for continued clock drift.
