摘要： A technique for analyzing Quality of Experience, QoE, of a delay critical robotic application in a cloud robotics system is disclosed, 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. A method implementation of the technique comprises triggering (S202) 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, triggering (S204) 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.

摘要： The present disclosure relates to delivery of data traffic over a wireless connection. In more particular, it relates to methods, a tunneling unit (208), and system for emulating wired connectivity between two or more robot devices (202, 204) and a controller (222). Buffering (212) of data frames, from two or more robot devices, received up-streams a wireless access network (206) is performed. Based on the time-stamps extracted (210) from data frames a relative time offset is determined for the two or more robot devices. Buffered uplink frames are forwarded (216) to the controller in a pre-define order, enabling using the relative time offset when forwarding downlink frames (232), being received over the wireless access network (206), to said two or more robot devices, such the that the downlink frames reach each one of two or more robot devices simultaneously. A deterministic delivery of data frames over a wireless connection is provided.

摘要： The present invention aims at an improvement of robot control monitoring and optimization in mobile networks in support of remote robot control services for robot devices. Heretofore, an analytics system (26) provides service quality information to a Cloud-based remote control system (22). Also, the Cloud-based remote control system (22) issues control requests to a local control unit (30) for control of a robotic device (24) and a mobile communication network (28) connects the Cloud-based remote control system (22) with the local control unit (30). Service event information is collected and associated with control requests issued by the Cloud-based remote control system (22). On the basis of the collected service event information a processing unit (30) correlates the service event information with the associated control request, calculates at least one key performance indicator from the result of correlation, analyzes the at least one key performance indicator for identification of a poor service quality incidence, and generates a service quality report based on the result of analysis upon occurrence of a poor service quality incidence.

摘要： In a multi flow HSDPA system comprising a RNC (402) and a plurality of NodeB's (404, 406), the present disclosure includes (re-) use of original active queue management, AQM, based congestion control, ABCC for a primary link (421). For every detected congestion, an end-user IP packet is destroyed. ABCC is not used for the secondary link (422), which means that application level TCP will not be informed about congestion on the secondary link (422). The radio link control, RLC, protocol data units, PDU, (432) are distributed among links based on the congestion status of the links. If secondary link (422) is congested then more packets will be transmitted on the primary link (421). This makes it possible to use TCP compatible congestion control for multi flow HSDPA, without the drawback that would result from TCP reacting unnecessarily on flow bitrate decrease.
