Abstract: The disclosure relates to optimistic QoS setup. A network element receives an IP packet that is not associated with a QoS request on a bearer for an application/service executing on a target client device, and initiates QoS activation for the target client device based on a combination of an application-specific identifier from the target client device and a user-specific identifier of the application/service. A server receives a session setup request that is not associated with a QoS request for an application/service executing on a target client device, the session setup request identifying one or more client devices to participate in a session, and initiates QoS activation for at least one of the client devices, before a session announcement is transmitted to the client devices, based on a combination of an application-specific identifier from the target client device and a user-specific identifier of the application/service.

Abstract: In an embodiment, an apparatus (e.g., a client device, an eNodeB, MME, S-GW, P-GW, UTRAN component, etc.) detects a first transition of a client device from an active state to an idle state while the client device is allocated a Quality of Service (QoS) link by a serving network. The apparatus caches QoS information associated with the QoS link, and releases the QoS link in response to the detection of the first transition. The apparatus later detects, after the caching and releasing, a second transition of the client device from the idle state back to the active state. The apparatus re-establishes the QoS link in response to the detection of the second transition using the cached QoS information.

Abstract: The disclosure is directed to group communications in a mixed casting services wireless communication system. An embodiment detects a loss of multicast coverage at a user equipment (UE), notifies a server of the loss of multicast coverage, wherein the server is configured to provide a desired multicast communication, and requests that communications related to the desired multicast communication be conducted on a unicast service using application layer signaling independent of link layer signaling.

Abstract: In an embodiment, an apparatus predicts traffic usage in uplink and downlink directions of a link that is configured to support a communication session for the client device. In an example, the predictions can be based upon a call state parameter (e.g., if the client device is a non-floorholder or is muted the client device is unlikely to send much traffic in the uplink direction, etc.). The apparatus initiates, in association with the communication session, (i) an uplink-specific QoS adjustment to a first level of Quality of Service (QoS) assigned to the uplink direction of the link based on the predicted traffic usage in the uplink direction, and/or (ii) a downlink-specific QoS adjustment to a second level of QoS assigned to the downlink direction of the link based on the predicted traffic usage in the downlink direction. The apparatus can correspond to the client device or alternatively to a server.

Abstract: The disclosure generally relates to optimized always-on wireless service using network assistance and keep-alives. More particularly, in response to a user equipment (UE) requesting a bearer for an always-on service, a network may establish the bearer for the always-on service and transmit an availability time that indicates a period during which the bearer will be held in an active state to the UE. Any applications running on the UE may then use the bearer for the always-on service, and the UE may transmit a single keep-alive message to the network before the availability time expires to reset the period during which the bearer will be held in the active state. Furthermore, the keep-alive message may be structured to not generate a reply and thereby reduce battery consumption, reduce communication overhead, and improve network capacity.

Abstract: In an embodiment, a server mediates a first group communication session with the user equipment (UE) by exchanging media for the first group communication session with the UE over a first link with a first level of Quality of Service (QoS) resources (e.g., either without a guaranteed bit rate (GBR) or a threshold amount of GBR) and exchanging non-media signaling data for the first group communication session with the UE over a signaling link that is either the same or separate from the first link. The server detects, while the UE continues participation in the first group communication session, that the UE has joined or is attempting to join a second group communication session. The server applies a policy for selectively allocating additional QoS resources to supplement the first level of QoS resources to the UE for concurrently supporting both the first and second group communication sessions in response to the detection.

Abstract: In an embodiment, a user of a wireless communications device (WCD) is notified when operating in a serving area of a FEMTO access point (AP). In another embodiment, the WCD can notify an application server (AS) that the WCD is served by the FEMTO AP. In another embodiment, the AS can set a service level for a server-arbitrated communication session (CS) based on the FEMTO AP serving status of participating WCDs. In another embodiment, the FEMTO AP can determine to use a downlink control or signaling channel to transmit data to the WCD. In another embodiment, based on its serving FEMTO AP status, the WCD can (i) modify its participation level in the CS and/or (ii) selectively track usage. In another embodiment, the WCD or FEMTO AP can measure performance parameters of the CS to determine whether to trigger a handoff of the WCD to a different AP.

Abstract: In an embodiment, an apparatus monitors traffic usage in uplink and downlink directions of a link that is configured to support a communication session for the client device. The apparatus can correspond to a core network component or to an access network component. The apparatus initiates, in association with the communication session, (i) an uplink-specific QoS adjustment to a first level of QoS assigned to the uplink direction of the link based on the monitored traffic usage in the uplink direction, and/or (ii) a downlink-specific QoS adjustment to a second level of QoS assigned to the downlink direction of the link based on the monitored traffic usage in the downlink direction. The link is maintained in both the downlink and uplink directions throughout the communication session irrespective of any QoS adjustments in the uplink and/or downlink directions of the link that occur during the communication session.

Abstract: In a first embodiment, an access network detects whether QoS links for both IMS and non-IMS sessions are allocated to a client device, whereby the non-IMS session is recognized as being associated with a particular application type. An SRVCC feature for the IMS session is disabled if the QoS link for the non-IMS session exists and carries at least a threshold level of traffic. In a second embodiment, a non-IMS session is supported by a first network with QoS and is then handed off to a second network. After the handoff, the second network supports the non-IMS session with an application-specific QoS configuration based on application-identifying information provided from the first network. In a third embodiment, a single or dual-transceiver client device is engaged in a non-IMS session with QoS. A page originating from a CS network is ignored if a do-not-disturb feature is activated for the non-IMS session.

Abstract: 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.

Abstract: Systems and methods for predictive QoS resource allocation in a wireless communication system are disclosed. An access network can detect a communication directed to an access terminal requiring QoS resources, send a page to an access terminal and allocate the QoS resources prior to receipt of the connection request from the access terminal.

Abstract: The disclosure relates to determining priority access with dual access barring classes. An aspect receives, at a client device, at least one high priority access barring class and at least one low priority access barring class, switches to the low priority access barring class, receives an access barring message, and switches to the high priority access barring class in response to receiving the access barring message. An aspect receives a call request for a high priority call among a group of client devices, transmits a notification to a network instructing it to transmit an access barring message in response to receiving the call request, wherein one or more members of the group of client devices switch to a high priority access class in response to receiving the access barring message, and suppresses call announcements for non-priority call requests after transmitting the notification.

Abstract: In an embodiment, objects are downloaded to an access terminal (AT) based on which window(s) are prominently displayed on the AT. In another embodiment, objects are downloaded to the AT based on a set of user-specified object download priorities. In another embodiment, a portion of a streaming data session to the AT is de-prioritized in response to a transition of a display of the AT from a first set of windows associated with the streaming data session to a second set of windows associated with a different session. For example, the de-prioritization can result in the portion (e.g., a video-portion of a audio and video conference) being omitted or reduced. In another embodiment, in response to the AT entering a limited environment, objects being downloaded to the AT can be dynamically altered to conform with the AT's limited environment.

Abstract: Embodiments are directed selectively mixing media at an application server arbitrating a group communication session for a communication group. In an embodiment, the application server receives media, from one or more session participants of the group communication session, for transmission to the communication group. The application server determines a number of session participants that are providing the received media. The application server determines whether to bypass the received media from entry into a de-jitter buffer based at least in part on the determined number, wherein the de-jitter buffer is configured to queue media from session participants for mixing by the application server during the group communication session. For example, the application server can determine to bypass the received media from entry into the de-jitter buffer if the number is below a threshold number. The application server transmits the received media to the communication group.

Abstract: In an embodiment, a communications device exchanges, between first and second access terminals, higher priority data in association with a communication session of a first type and also lower priority data in association with a communication session of a second type. If the communications device determines a transition of the first access terminal to a lower data-rate environment, the communication device reduces a size of data packets exchanged between the first access terminal and an application server for the communication session of the second type. If the communications device determines an upcoming data packet is a low-data packet (e.g., a silence packet), the low-data packet is suppressed. If the communications device determines that the first access terminal has attempted transmission of a set of last or near-last data packets in the sequence, the communications device re-transmits the set of last or near-last data packets without waiting for ACKs.

Abstract: Embodiments include managing a reverse link transmission power level setpoint during periods of data inactivity on a reverse link traffic channel in a wireless communications system. At an access terminal, upon detecting reverse link data inactivity above a time threshold, a message is generated and transmitted on the reverse link traffic channel at a power level sufficient for the access network to measure transmission statistics to determine whether to adjust the current transmission power level setpoint of the access terminal. Alternatively, the access terminal notifies the access network of an upcoming reverse link data inactivity period, and then lowers its transmission power level setpoint to reduce power consumption during the reverse link data inactivity period. Then, upon detection of a potential reverse link data transmission, the access terminal may then send one or more messages to prompt the access network to modify the access terminal's transmission power level setpoint.

Abstract: The disclosure is directed to prioritizing call announce response in a broadcast/multicast communication system. An embodiment establishes a first priority for response based on assigning each user equipment (UE) a first random delay for response to a first call announce, responds to the first call announce using the first random delay, and determines a second priority for response to a subsequent call announce based on an elapsed time that each UE is present in a multicast area.

Abstract: At least one embodiment of the invention is directed to communicating in a wireless communications system, including monitoring a communication session on a first network, ignoring pages from a second network during the communication session, the first and second network configured for operation on different physical layers, and upon termination of the communication session over the first network, selectively sending a query to an application server to request information related to failed attempts by the application server to contact the access terminal on the second network during the communication session.

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: A method of wireless communication includes intercepting a request from an application desiring use of communication resources. The intercepted request is held and is then evaluated to determine whether the held request can be released. The held request is released based on the outcome of the evaluation.
