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: The disclosure generally relates to network-initiated and client-initiated mechanisms to enable quality of service (QoS) for web-based client applications that may high efficiency, high performance, or otherwise guaranteed service levels. For example, to enable QoS for calls or other sessions associated a web-based application, one or more signaling messages may be exchanged between a server and a first user equipment (UE) to establish a call between the first UE and a second UE and to establish a peer connection between the server and at least the first UE. As such, QoS may be activated for at least the peer connection between the first UE and the server, wherein the server may route data associated with the web-based application between the first UE and the second UE over the established peer connection to implement the activated QoS.

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: A user equipment (UE) selectively attempts recovery of lost media for a real-time communication session. In an embodiment, the UE detects presence of a lost media packet from another UE participating in the real-time communication session that did not successfully arrive at the UE. The UE evaluates a set of recovery criteria associated with the lost media packet to attempt to dynamically select at least one external source from a plurality of external sources from which the lost media packet can potentially be recovered at different predicted reliabilities and/or response times for attempting recovery of the lost media packet based on the set of recovery criteria. The UE attempts to recover the lost media packet from the selected at least one external source based on the evaluation.

Abstract: The disclosure relates to dynamically controlling group priority access to a wireless network for a plurality of subscriber devices. An aspect transmits, on a broadcast/multicast interface, a priority group list indicating a priority state of at least one communications group of subscriber devices, wherein a subscriber device is barred from performing channel access procedures when at least one group identifier of the priority group list does not match at least one group identifier of a list of group identifiers of the subscriber device. An aspect receives, on a broadcast/multicast interface, a priority group list indicating a priority state of at least one communications group of subscriber devices, and bars channel access procedures when at least one group identifier of the priority group list does not match at least one group identifier of a list of group identifiers of the subscriber device.

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, 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: The disclosure relates to group communications over multimedia broadcast-multicast services (MBMS). An embodiment of the disclosure establishes a first multicast flow and assigns a second multicast flow, wherein the second multicast flow contains signaling and media for at least one group call, and wherein the first multicast flow is configured to send information regarding activity on the second multicast flow. An embodiment of the disclosure monitors a first multicast flow for an announce message regarding a first group call, and upon receipt of the announce message, switches to a second multicast flow that contains signaling and media for the first group call.

Abstract: The disclosure is directed to group communications over evolved multimedia broadcast/multicast services (E-MBMS). An embodiment identifies a schedule for an indicator on a broadcast/multicast medium of a first multicast media on a multicast flow, wherein the indicator is configured to identify a location of data on the broadcast/multicast medium and to identify a presence of the data on the multicast flow, binds application layer paging, an application layer wake up mechanism, or a power saving mechanism to the schedule for the indicator on the multicast flow, wakes from a sleep mode to monitor the indicator to determine availability of the first multicast media based on the indicator, tunes to the first multicast media if the first multicast media is available, and returns to the sleep mode, if the first multicast media is not available.

Abstract: The disclosure is related to dynamically applying quality of service (QoS) to a call. An aspect determines a packet transmission state of a subscriber on the call, determines whether or not the QoS is allocated to the subscriber, and allocates the QoS to the subscriber based on the QoS not being allocated to the subscriber and the packet transmission state indicating that the subscriber is sending packets.

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: In an embodiment, a first MBSFN area is configured to support a higher data rate than a lower data rate portion of a second MBSFN area, and an application server executes a common data rate mode by delivering a data stream for a group session to the first and second MBSFN areas via IP multicast at a common data rate that is regulated by quality feedback. In a further embodiment, the application server exits the common data rate mode and delivers the data stream to the first MBSFN area via IP multicast at an MBSFN-specific data rate that is higher than the common data rate, while delivering the data stream to the lower data rate portion of the second MBSFN area via IP unicast. In another further embodiment, the application server resumes the common data rate mode.

Abstract: Systems, methods, and devices for managing audio streams in a group communication session. A processor of a receiving communication device may send to a transmitting communication device an instruction to adjust a gain of an audio stream of the transmitting communication device via a feedback communication link. A processor of the transmitting communication device may receive the instruction and may adjust the gain of the audio stream responsive to the instruction. The processor of the transmitting communication device may transmit the audio stream using the adjusted gain.

Abstract: Methods and systems are disclosed for preemptively establishing a multicast bearer. An embodiment determines whether adding a multicast session to a plurality of multicast bearers will exceed a high bandwidth threshold, requests setup of a new multicast bearer if adding the multicast session will exceed the high bandwidth threshold, and hosts the multicast session on an available one of the plurality of multicast bearers or the new multicast bearer.

Abstract: The disclosure generally relates to techniques that may be used to coordinate an evolved multimedia broadcast/multicast services (eMBMS) geo-location based group call. More particularly, an eMBMS bearer may be established to support a group call based on a mapping among eMBMS network components that service a geographic area selected by an originator associated with the group call (e.g., an area that the call originator defines according to latitude and longitude coordinates, a selected region on a map that displays available group members in the selected region, network identifications, etc.). The group call may then be initiated over the established eMBMS bearer using network group identifiers associated with the call originator and one or more group members present in the selected geographic area and unicast service with a dedicated link to group members located outside the selected geographic area may be established to include such group members in the group call.

Abstract: In an embodiment, a server determines a first support state for the group communication session that defines a first set of sectors belonging to a multicast/broadcast single frequency network (MBSFN) area for transmission of the session media for the group communication session via Internet Protocol (IP) multicast. The server then transitions the group communication session from the first support state to a second support state that defines a second set of sectors belonging to the MBSFN area for transmission of the session media for the group communication session via IP multicast. Before the transition, the server delivers the session media to the first set of sectors via IP multicast in accordance with the first support state. After the transition, the server delivers the session media to the second set of sectors via IP multicast in accordance with the second support state.

Abstract: The disclosure is related to group communications over multimedia broadcast/multicast services (MBMS). An aspect determines whether a number of one or more user devices in an MBMS coverage area participating in a group call is less than a threshold, and delivers a media stream for the group call to a user device of the one or more user devices over a wireless local area network (WLAN) to which the user device is connected based on the number of the one or more user devices in the MBMS coverage area being less than the threshold.
