    Abstract: Various embodiments include methods and user equipment (UE) for mobile-terminated call handling when a latency-sensitive service (LSS) is active on the UE. Embodiments may include determining a radio access technology (RAT) used for a latency-sensitive service (LSS) currently active on the UE in response to receiving an MT call invitation and determining whether a latency-prone service command is received that includes service commands configured to change the determined RAT used for the LSS to another RAT likely to compromise the LSS. In response to determining that a latency-prone service command is received the MT call invitation may be rejected, but in response to determining that a latency-prone service command is not received, MT call alerting may be allowed.

    Abstract: Techniques for setting up a packet-switched video telephony (PSVT) call are described. A mobile originated (MO) device may transmit an invitation for the PSVT call to a mobile terminated (MT) device. The invitation may initiate a process to reserve and identify video and audio resources to establish the PSVT call. The MO device may determine whether the video resources are available. If the video resources are not available but audio resources are available, the MO device may instead establish the PSVT call with only an audio stream call between the MO device and the MT device. If audio resources become available ahead of video resources, the PSVT call may be established with an audio stream first and a video stream is automatically added to the call when video resources are reserved later, or the PSVT call is downgraded to a VoIP call if the video resources cannot be reserved.

    Abstract translation: 描述了用于建立分组交换视频电话（PSVT）呼叫的技术。 移动发起（MO）设备可以向移动终止（MT）设备发送针对PSVT呼叫的邀请。 邀请可以启动一个过程来保留和识别视频和音频资源以建立PSVT呼叫。 MO设备可以确定视频资源是否可用。 如果视频资源不可用但音频资源可用，则MO设备可以仅用MO设备与MT设备之间的音频流呼叫建立PSVT呼叫。 如果音频资源在视频资源之前变得可用，那么PSVT呼叫可以首先与音频流建立，并且当稍后保留视频资源时自动将视频流添加到呼叫，或者如果PSVT呼叫被降级为VoIP呼叫 视频资源无法保留。
