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: The disclosure uses a low-cost local wireless network to expand coverage of a multicast service. A user device determines whether a signal strength for a detected wireless multicast service is greater than a threshold, determines whether a low cost local wireless network is available, and communicates with an application server over the low cost local wireless network based on the signal strength being not greater than the threshold and the low cost local wireless network being available. A server receives a request from a user device to send multicast communications to the user device over the low cost local wireless network serving the user device, wherein the user device sends the request based on a signal strength of a detected wireless multicast network being less than a threshold and the low cost local wireless network being available, and communicates with the use device over the low cost local wireless network.

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: 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: 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: 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 translation: 在一个实施例中，服务器通过在具有第一级服务质量（QoS）资源的第一链路上交换用于与UE的第一组通信会话的媒体来介入与用户设备（UE）的第一组通信会话（例如， 无需保证比特率（GBR）或GBR的阈值量），并且通过与第一链路相同或分离的信令链路与UE通过非媒体信令数据交换第一组通信会话。 当UE继续参与第一组通信会话时，服务器检测到UE已经加入或正试图加入第二组通信会话。 服务器应用策略，用于选择性地分配附加QoS资源以补充UE的第一级QoS资源，以同时支持响应于该检测的第一和第二组通信会话。

Abstract: In an embodiment, a UE performs an IRAT handoff from a source network with a first RAT to a target network with a second RAT, and obtains a channel from the target network. The UE reports a level of QoS on the channel to a server via the target network. The server issues instructions to the UE and/or the target network for modifying the level of QoS in response to the report based on if the level of QoS is insufficient to support a particular type of communication session. In another embodiment, in conjunction with an IRAT handoff, the source network sends a handoff preparation message to the target network to facilitate the target network to initiate setup of a set of channels with a non-IMS application-specific QoS configuration for the UE on the target network in conjunction with the handoff.

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 translation: 在第一实施例中，接入网络检测用于IMS和非IMS会话的QoS链路是否被分配给客户端设备，由此非IMS会话被识别为与特定应用类型相关联。 如果非IMS会话的QoS链路存在并且携带至少一个阈值级别的流量，则IMS会话的SRVCC功能被禁用。 在第二实施例中，非IMS会话由具有QoS的第一网络支持，然后被切换到第二网络。 在切换之后，第二网络基于从第一网络提供的应用识别信息来支持具有特定于应用的QoS配置的非IMS会话。 在第三实施例中，单个或双收发器客户端设备参与具有QoS的非IMS会话。 如果为非IMS会话激活不干扰功能，则会忽略来自CS网络的页面。
