摘要： This Application describes mechanisms to provide priority levels for call connection requests and/or messages from a sending device to a receiving device. The receiving device is configured to allow prioritized notification alerts for incoming call connection requests and/or for incoming messages from a sending device to override a silent or do not disturb mode for one or more contacts based on i) a priority level provided with the call connection request or message and ii) a priority setting for the sending device or a set of devices associated with a user of the sending device.

摘要： Apparatuses, systems, and methods for improving efficiency in IMS registration and management in a wireless communication device, such as a UE. In some scenarios, the UE may, while implementing IMS services (e.g. for VoLTE) over a wireless communication link with a cellular network, determine that the wireless communication link is not performing at an acceptable level. In response, the UE may start a timer and buffer IMS SIP signaling messages while the timer is running. If the wireless communication link performance is restored to an acceptable level before expiration of the timer, the UE may transmit the buffered IMS SIP signaling messages. If the timer expires prior to restoration of the wireless communication link, the buffered messages may be cleared, and the UE may locally deregister from IMS registration and IMS PDN. In some scenarios, select IMS SIP signaling messages may be omitted or removed from the buffer.

摘要： Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for EPS fallback when initiating a voice call while camped on a 5G cell. The UE may camp on a 5G network by performing an IMS registration procedure/IMS SIP invite procedure with an IMS. The UE may initiate a voice call and determine that the voice call cannot be established over the 5G NR network. In response, the UE may perform a TAU procedure or an attachment procedure with a cell of a 4G network. The IMS may be transferred to the 4G network during TAU/attachment procedure. The UE may, in response to determining that it is barred from the 4G network, transition back to the 5G network and transmit, to the 5G NR network, a SIP cancel request to allow a context associated with the UE to be cleared from the IMS.
