Systems and methods are provided to improve candidate search and measurement in non-standalone (NSA) and standalone (SA) 5G new radio (NR) multi-radio access technology (RAT) environments. For Evolved Universal Terrestrial Radio Access Network (E-UTRAN) NR-dual connectivity (EN-DC), a user equipment (UE) skips 5G band measurements for an initial search or an out-of-service (OOS) search. For SA dual connectivity, the UE avoids 5G remaining band (RBS) scans and limits 5G deviated band search (DBS) scans to bands configured for the carrier.

The present application relates to a slice selection method, and a terminal device. The method includes the terminal device receives deployment-related slice information; and the terminal device selects a slice based on the deployment-related slice information. In an embodiment of the present application, based on the deployment-related slice information, an preferred slice can be selected, which reduces access and business service delay for the terminal device.

Techniques are described by which a network management system (NMS) is configured to monitor and/or control a wireless network based on one or more roaming quality assessments. The NMS determines one or more roaming quality assessments for each roaming event and/or each network device in the wireless network. The roaming quality assessments include one or more of a roaming latency score, a signal quality score and/or a stability score. The roaming quality assessments may further include one or more suboptimal roam scores, sticky client scores, and/or interband scores. The NMS may further detect one or more ping-pong roaming events or excessive roaming events.

A cell reselection method includes generating, by a radio access network device, cell reselection information, wherein the cell reselection information includes an identifier of at least one carrier frequency and an identifier of a network slice supported by each of the at least one carrier frequency. The cell reselection method further includes sending, by the radio access network device, the cell reselection information to a terminal device, wherein the cell reselection information is useable by the terminal device for cell reselection.

A method of acting upon a restriction in services for an unmanned aerial vehicle, UAV, wherein the UAV is connected to a telecommunication network and wherein the UAV is allowed to utilize one or more services within the telecommunication network, the method comprising the steps of receiving, by the UAV, from a base station in the telecommunication network, access information for being served by the base station, determining, by the UAV, from the access information that at least one service of the one or more llowed services is restricted, determining, by the UAV, an action to be performed based on the at least one restricted service, the action eing at least one of a communication service modification of the UAV, and a physical action of the UAV, and finally performing, by the UAV, the action.

The embodiments disclosed herein include capturing images via cameras or light sensors of a mobile communication device, processing the image to determine obstructed (e.g., by foliage) portions and unobstructed (e.g., open sky) portions of the images, and generating a grid indicating the obstructed and unobstructed portions. The device may then adjust operating characteristics, such as synchronizing with a communication hub or other mobile communication device, performing a handover with the communication hub or other mobile communication device, determining transmission power or an amount to increase transmission power, selecting an antenna, determining a beam direction, determining a discontinuous reception cycle or a frequency for receiving data, providing an indication to stop or proceed through certain areas (e.g., to take advantage of areas with higher signal quality or avoid areas with lower signal quality), and the like, based on the obstructed and unobstructed portions identified in the grid.

A first base station receives, from a second base station with a plurality of cells, a message that includes a served cell information element for each cell of the plurality of cells, where the served cell information element for each cell indicates whether a respective cell supports at least one vehicle-to-everything (V2X) service. The first base station makes a dual connectivity decision for a wireless device. The first base station sends, to the second base station, a secondary node addition request for the wireless device based on the dual connectivity decision and the message.
