Abstract: 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.

Abstract: A device, system, and method uses a high power mode for a cellular connection. The method is performed at a device that is configured to establish a network connection to a network. The method includes detecting a number of at least one event that has occurred over a time period, the at least one event associated with operations used through the network connection, the at least one event indicative of a power to perform the operations that is greater than a predetermined power. When the number is at least a predetermined threshold, the method includes identifying the network connection as being in a high power state. The method includes activating settings when the network connection is in the high power state, the settings reducing a usage of the operations over the network connection.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for de-registration of the wireless device from a first access type over a second access type. Methods also include procedures for maintaining state machines associated with both access types as well as procedures to determine a connection for re-transmitting a de-registration request and to avoid collisions between procedures associated with the first and second access types. Further, methods include an information element configured to indicate which access type has been de-registered.

Abstract: A device, system, and method detect an activity and utilize a mitigation scheme. The method is performed at a device that is configured to establish a network connection to a network, the network including a plurality of areas, each area being defined based on a grouping of a plurality of neighboring cells, the device being associated with one of the areas at a select time. The method includes determining between an activity status and a non-activity status associated with the device. When the activity status is determined, the method includes determining an area update rate indicating a number of changes to the associated area over a period of time. When the area update rate exceeds a predetermined update rate threshold, the method includes selecting a mitigation scheme configured to reduce an amount of power used by the device.

Abstract: A wireless communication device (UE) may perform wireless communications according to at least a first radio access technology (RAT) and a second RAT. When the UE is in idle-mode, it may determine whether to bias a RAT selection policy—which may be presently favoring networks operating according to the first RAT—towards the second RAT, based on one or more of the following: first information indicative of a quality of previous wireless communications performed by the UE according to the first RAT, second information indicative of an overall quality of wireless communications performed according to the first RAT by the UE over a specified period of time at a specific location where the UE is presently located, and/or third information indicative of an overall quality of wireless communications performed according to the first RAT by other UEs presently located at the specific location.

Abstract: This disclosure relates to transport link selection for an accessory wireless device in association with a companion device. The accessory device may communicate via a short range wireless communication link with the companion device. The companion device may detect an event and, based on the event, transmit assistance information to the accessory device. The accessory device may evaluate various conditions. The accessory device may select a transport link and/or short range link based at least in part on the received assistance information and/or the evaluated conditions.

Abstract: A user equipment device (UE) may receive a schedule for a listen before talk (LBT) procedure for a secondary component carrier on a first subscription associated with the UE that includes a radio frequency resource of the UE. The UE may determine a requirement to perform at least one operation on a second subscription associated with the UE that also includes the radio frequency resource. The UE may determine that performance of the at least one operation (at least partially) interferes (time overlaps) with performance of the LBT procedure. In response, the UE may initiate at least one scheduling operation at the UE to avoid interference between performance of the at least one operation on the second subscription and performance of the LBT procedure on the first subscription.
