Abstract: A device sets an activity mode for a cellular connection. A method to set the activity mode is performed at a device located with a user that is configured to establish a network connection to a network. The method includes determining a status of the user, the status indicating an activity state or a non-activity state of the user. The method includes, when the status indicates the activity state, activating an activity mode on the device that restricts select types of mobile originating data traffic.

Abstract: Methods related to an inactive state of a user equipment (UE). In one example, when an amount of data in an uplink buffer is less than a threshold, the data is sent to the network while remaining in the inactive state. In another example, when reselecting to a different cell, the UE attempts to reselect to the different cell and remain in the inactive state. When transitioning to a connected state at the reselected cell, the UE sends a resume request including an identification of the first cell. In another example, when a high priority or a background PLMN search is performed in the inactive state, the results are cached and implemented the earlier of when a timer expires or the UE enters an idle state. In another example, a cell reselection criteria is altered in the inactive state to make it less likely that a cell reselection will occur.

Abstract: Method and apparatus for adaptive data collection operations where a first user equipment (UE) is paired to a second UE. The first UE may receive capability data from the second UE, the capability data comprising cellular capabilities of the second UE. The first UE may further collect service history data for the second UE, where the service history data corresponds to the cellular capabilities indicated by the capability data. The first UE may further transmit the service history data to the second UE.

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 device, system, and method estimate a link budget on a companion device. The method is performed at a first device connecting to a second device over a first connection and a network over a second connection, the second device connecting to the network over a third connection. The method includes receiving initiating data from the second device based on radio conditions associated with the third connection. The method includes, when the first device disconnects from the second device and establishes the second connection, determining an initial network metric value based on the initiating data that is used to estimate radio conditions associated with the second connection. The method includes selecting a data exchange mode of the first device based on the initial network metric value which is used until a further network metric is determined by the first device.
