Technique for analyzing QoE of a delay critical robotic application

A computing unit for analyzing Quality of Experience (QoE) of a delay critical robotic application in a cloud robotics system, the robotic application involving use of a cloud-based service by a robot, the service being provided to the robot from a cloud using a connection over a mobile communication network, the computing unit comprising at least one processor and at least one memory, the at least one memory containing instructions executable by the at least one processor such that the computing unit is operable to:

• trigger determining whether a QoE measure associated with the robotic application exceeds a threshold to assess whether QoE degradation is present;
• and
• when it is determined that QoE degradation is present, trigger identifying a root cause for the QoE degradation based on one or more performance indicators observed within the mobile communication network and associated with the connection.
