Abstract: Embodiments herein provide mechanisms for viewport dependent adaptive streaming of point cloud content. For example, a user equipment (UE) may receive a media presentation description (MPD) for point cloud content in a dynamic adaptive streaming over hypertext transfer protocol (DASH) format. The MPD may include viewport information for a plurality of recommended viewports and indicate individual adaptation sets of the point cloud content that are associated with the respective recommended viewports. The UE may select a first viewport from the plurality of recommended viewports (e.g., based on viewport data that indicates a current viewport of the user and/or a user-selected viewport). The UE may request one or more representations of a first adaptation set, of the adaptation sets, that corresponds to the first viewport. Other embodiments may be described and claimed.

Abstract: Methods and systems for sending multicast messages are disclosed. A multicast message is received to be transmitted to a plurality of access terminals at a radio access network (RAN), the received multicast message having a first format. The first format may correspond to a conventional multicast message format. The RAN determines whether the received multicast message requires special handling. If the RAN determines the received multicast message requires special handling, the radio access network converts the received multicast message from the first format into a second format. The RAN transmits the converted multicast message with the second format (e.g., a data over signaling (DOS) message) on a control channel to at least one of the plurality of access terminals. The access terminals receiving the converted multicast message interpret the message as a multicast message.

Abstract: Systems and methods for hybrid call setup in a wireless communication system are disclosed. A page is sent on a first network informing a target device of a pending communication on a second network. The page also informs the target device a short data burst (SDB) will be sent on the first network. The short data burst (SDB) is sent on the first network containing setup information regarding the pending communication on the second network.

Abstract: In an example, an access terminal sends a group member report to an access network, the group member report indicating a location of the access terminal and at least one multicast group, the group member report being sent before a multicast session associated with the multicast group is initiated, determines a location update rule, the location update rule being a manner in which to report location updates of the access terminal to the access network and reports location updates of the access terminal to the access network based on the determined location update rule.

Abstract: Aspects of managing acknowledgment transmissions from multicast group members of a multicast group within a wireless communications network are disclosed. An access network transmits an announce message announcing a multicast session to a plurality of access terminals. One of the plurality of access terminals (i.e., a first responder) sends a BCMCSFlowRegistration message and an announce acknowledgment (ACK) message to the access network. In an example, the BCMCSFlowRegistration message and announce ACK message are sent within the same access probe on a reverse link access channel. Next, the access network sends, in response to the received BCMCSFlowRegistration message, a suppression message to request access terminals not to send announce acknowledgment messages for the announced multicast session. Alternatively, an application server sends the suppression message in response to the received announce ACK message.

Abstract: 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.

Abstract: An access network determines to transmit multicast messages on a downlink shared channel. The access network receives a multicast registration message and a traffic channel request from at least one access terminal. The access network assigns a traffic channel to the at least one access terminal, and transmits the multicast messages on the downlink shared channel. In another example, the access network can determine a channel type upon which the support a multicast session, can indicate the channel type selection to the at least one access terminal in an announce message and can then transmit the multicast messages for the multicast session on the selected channel type. The at least one access terminal receives the announce message, requests a traffic channel and receives a traffic channel assignment, registers to the multicast session and monitors the downlink shared channel for multicast messages.

In one embodiment, the wireless communication device registers at the communication control device, such as a base station controller, and at least one interface is established between the communication control device and another computer device on the wireless communication network, such as a broadcast A10 interface with a broadcast serving node (BSN). The communication control device will then maintain the interface while the at least one wireless communication device, or at least one member device of the communication group, is registered such that group communications can more rapidly be delivered to the wireless communication device.

Abstract: In various embodiments, a mobile device and/or the presence-aware applications running on the device may be configured to support multiple user profiles. For instance, multiple users with access to the same mobile device may each create a user profile and login credentials on that device, and each user may take turns using the mobile device. The mobile device may also allow multiple users to access the mobile device simultaneously. In such embodiments, the mobile device processor executing the presence module and/or presence engine may be configured to associate a particular user profile with a request for updated presence information and determine whether to update the presence information based at least in part on the that user profile.
