摘要： A method, apparatus, and computer program product for wireless communication are provided. The method generally includes registering a UE with an internet protocol multimedia subsystem (IMS) server for one or more native services and non-native services, wherein the UE comprises a modem processor and an application processor. The IMS server may comprise an RTP stack, wherein a portion of the RTP stack resides on the MP and a portion on the AP. A data packet may be received having an identifier of one of the native or non-native services. The data packet may be received from a WWAN or IWLAN. The data packet may be forwarded to the MP or to the AP based on the identifier. According to aspects, the data packet is forwarded to the MP if the identifier indicates an audio service and to the AP if the data packet indicates a video service.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, while the UE is in an active session using a first radio access technology (RAT) associated with a first subscription of the UE, a call request via the first RAT, wherein the call request is associated with a second subscription of the UE. The UE may determine that the call request is received from a serving cell that is associated with fallback from the first RAT to a second RAT for calls. The UE may reject the call request or transition the second subscription to a third RAT based at least in part on the determination that the call request is received via the serving cell that is associated with fallback from the first RAT to the second RAT for calls. Numerous other aspects are described.

摘要： Techniques described provide for transferring calls between a first user equipment (UE) and a second UE. One implementation may include receiving a request to transfer a call, which has been established established between the first UE and a third party device, to be between a second UE and the third party device. Location information for the first and second UEs may be received. A determination may be made to determine whether the first and second UE are in proximity to each other. In the event that a determination is made that the first and second UE are in proximity to each other, the established call may be transferred from the first UE to the second UE. Other aspects and features are also claimed and described.

摘要： Techniques are described for wireless communication. One method includes determining at a first time that a voice call is routed over a wireless local area network (WLAN); restricting an application processor from entering a first sleep state based at least in part on determining that the voice call is routed over the WLAN; determining at a second time that the voice call is offloaded from the WLAN to a wireless wide area network (WWAN); and enabling the application processor to enter a second sleep state based at least in part on determining that the voice call is routed over the WWAN.

摘要： A system and method for rate-adaptation of a video telephony (VT) session is disclosed. In one example, there is provided a method that includes receiving a first information set indicative of a start of a handover of a device from a first Radio Access Technology (RAT) to a second RAT. The method further includes receiving a second information set indicative of an end of the handover. The method further includes adjusting a rate-adaptation protocol for the VT session based at least in part on the first and second information sets.

摘要： Methods, systems, and devices are described for media synchronization. Multi-stream media processes may include media streams captured with respect to different clock rates. Multi-processor implementations may involve separate clocks associated with different media streams, such as audio and video, respectively. The separate clocks may tend to drift from one another, becoming further out of sync as time passes. Selecting a reference time of one of the processors to function as a “wall clock,” recording frame capture times with respect to the reference time, accounting for propagation delays, and transmitting frame capture times in terms of the reference time may aid in AV synchronization at a device where audio and video streams are received.

摘要： Methods, systems, and devices for wireless communications are described. A system may support techniques for triggering user equipment (UE) assistance information (UAI) based on mobility, wake up signal (WUS) configuration, or both. In some cases, a UE may communicate with a network node (e.g., a base station) on a first channel according to a discontinuous reception (DRX) configuration. The UE may determine that a speed of the UE satisfies a mobility threshold and may transmit UAI requesting one or more updated DRX configuration parameters based on the speed of the UE satisfying the mobility threshold. Additionally or alternatively, the UE may receive signaling configuring the UE to monitor for WUSs and may transmit UAI requesting one or more updated DRX configuration parameters based on the WUS configuration. The UE may receive control signaling configuring the DRX configuration with the one or more requested parameters in response to the UAI.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, during an active call on a first radio access technology (RAT), that a first condition for performing a handover from the first RAT to a second RAT is satisfied. The UE may determine that the second RAT would trigger a fallback to a third RAT after the handover from the first RAT to the second RAT and that a second condition for performing a handover from the third RAT to the first RAT is satisfied. The UE may refrain from performing the handover from the first RAT to the second RAT based at least in part on the determination that the second RAT would trigger the fallback and the determination that the second condition is satisfied. Numerous other aspects are provided.
