Abstract: An AMF receives, from a wireless device, a first registration request message for a first access path of an access type via a first access node. The AMF determines a common security context for the wireless device and sends, to the first access node, a first access stratum (AS) key, wherein the first AS key is based on a first value associated with the first access path and the common security context. The AMF receives, from the wireless device a second registration request message for a second access path of the access type via a second access node, and sends, to the second access node, a second AS key, wherein the second AS key is based on a second value associated with the second access path and the common security context.

Abstract: A method can include communicating, by a wireless device in a radio resource control (RRC) idle state or an RRC inactive state and with a first base station, packets associated with a service. The method can also include determining a quality-of-experience (QoE) of the service based on the communicating the packets. The method can further include sending, to a second base station, a first RRC message indicating that a measurement report associated with QoE of the service is available. The method can additionally include sending, to the second base station, a second RRC message that includes the measurement report. The measurement report can include the QoE of the service and area information associated with the QoE of the service.

Abstract: Multiple access paths may allow a wireless device to communicate with a plurality of network nodes simultaneously. Multiple access policy information may be sent to the wireless device. Using the multiple access policy information, the wireless device may determine to perform one or more registration requests over multiple access paths and one or more network slices to request for the access paths. The wireless device may send the registration requests, including the network slices, over the multiple access paths.

Abstract: A first base station receives, from a core network element, a context message comprising an initial context setup request or a user equipment (UE) context modification. The context message comprises a quality of experience (QoE) measurement collection (QMC) configuration for a second base station associated with a wireless device. The first base station determines QMC activation for the second base station; and sends, to the second base station, a request including the QMC configuration. The first base station receives, from the second base station, a QoE measurement report associated with the second base station; and transmits the QoE measurement report to a multi-cell/multicast coordination entity (MCE).

Abstract: The present disclosure provides an apparatus for measuring three-dimensional shapes by using moire interference, which comprises a unit calibration unit, an integrated calibration unit and a phase calibration unit. The unit calibration unit is configured to use a phase difference between two adjacent measuring points for obtaining a unit calibration value of an absolute moire order. The integrated calibration unit is configured to calibrate the absolute moire order up to a target point by using the unit calibration values. The phase calibration unit is configured to calibrate a phase of the target point by using the absolute moire order.
