Abstract: Apparatuses, systems, and methods for user equipment (UE) devices to perform a postponement of a data service request are described. A UE may detect a data service request failure during cell reselection and postpone a resend of the data service request based on a status of the cell reselection. The status may be an indication that the UE is attempting to camp on a cell or that the UE is monitoring one or more metrics associated with cell reselection. To postpone the data service request, the UE may postpone the data service request for a specified period of time or until the cell reselection is complete. The status may be monitored on a first layer of a protocol stack and the data service request may generated by a second layer of the protocol stack. The postponement may be for a fixed or variable time period.

Abstract translation: 描述用于执行数据服务请求延迟的用户设备（UE）设备的设备，系统和方法。 UE可以在小区重选期间检测数据服务请求失败，并且基于小区重新选择的状态推迟数据业务请求的重发。 该状态可以表示UE尝试驻留在小区上，或者UE正在监视与小区重选相关联的一个或多个度量。 为了推迟数据服务请求，UE可以延迟数据服务请求一段指定的时间，或者直到小区重选完成。 可以在协议栈的第一层上监视状态，并且数据服务请求可以由协议栈的第二层生成。 推迟可能是固定的或可变的时间段。

Abstract: This disclosure relates to inter radio access technology management for audiovisual calls. Wireless link availability and suitability for an audiovisual call may be evaluated for each of a first radio access technology and a second radio access technology. One or more wireless links on which to establish an audiovisual call may be selected based on the evaluations. The audiovisual call may be established on the selected wireless link(s). Wireless link availability and suitability for an audiovisual call may be monitored during the audiovisual call and decisions on whether to perform handover to a different wireless link and/or media duplication on multiple wireless links may be made based on the suitability for an audiovisual call of available wireless links.

Abstract: A voice over Long Term Evolution (VoLTE) capable mobile device is configured to deregister from an Internet Protocol (IP) Multimedia Subsystem (IMS) network element for voice connections and use a dual network mode of operation that includes data connections via a 4G LTE/LTE-A network and voice connections via a legacy 3G or 2G network based on performance metrics a serving cell of the 4G LTE/LTE-A network. When the performance metrics indicate that voice connections may be unstable, such as when a reference signal received power (RSRP) falls below a threshold level but remains above a reselection/handover threshold level, the mobile device deregisters from the IMS network element to disable VoLTE connections from being established. The mobile device establishes the requested voice connection via a legacy 3G or 2G network instead, while established or new data connections for the mobile device continue to use the 4G LTE/LTE-A network.

Abstract: Embodiments are presented herein of techniques for a mobile device to control timing of inter-RAT handovers. In some embodiments, an apparatus includes one or more processing elements configured to execute an interactive wireless communication application using a wireless communication configuration between the apparatus and a communications network for a first RAT. In some embodiments, the wireless communication configuration does not have a QoS guarantee. In some embodiments, the apparatus is configured to store information from the communications network that specifies one or more wireless thresholds relating to handover from the first RAT to a second RAT. In some embodiments, based on executing the application and current wireless conditions, the apparatus is configured to send a report to a base station of the communications network, prior to at least one of the thresholds being met, to trigger a handover from the first RAT to the second RAT.

Abstract: A source device connected to a sink device over a first wireless connection. The source device identifies a frame for retransmitting a voice packet associated with a real time application from the source device to the sink device, determines that a precedent operation is scheduled for the frame, delays the precedent operation to a subsequent frame, following the retransmitting of the voice packet and scheduling a retransmission operation for retransmitting the voice packet during the frame.

Abstract: Methods and apparatus to manage communication sessions to handover between a direct connection at a secondary wireless device and a relayed connection to the secondary wireless device via a primary wireless device. A connection manager of a secondary wireless device can trigger transfer of a communication session based on measurements of performance metrics for the communication session. Upon detection of performance degradation in a local connection or a backhaul connection or both, the connection manager of the secondary wireless device can determine proximity of and/or capabilities for connections of the primary wireless device and instigate transfer of the communication session between different connection types, such as between a direct connection and a relayed connection. The transfer of the communication session can occur without user intervention or in response to input from the user without interrupting or reestablishing the communication session.
