摘要： The present disclosure relates to a Web server (104, 60, 70) and a method therein of determining a trajectory for controlling of a robot device over a cloud interface. From a URI-encoded HTTP request (402) for the trajectory between a first pose and a second pose of the robot device, it is determined (S112, 408) the length of matching between cached trajectories and the trajectory requested. The longest length of matching is compared (S114, 410) to a minimal matching length (406), and if the longest length is longer than the minimal matching length, a HTTP response is sent (S122, 412) comprising the trajectory being determined. If the longest length is shorter than the minimal matching length, a HTTP request to calculate is sent (S116, 414). Currently available web service architecture can be reused, and easily up-scaled.

摘要： A technique of triggering transition control between different RRC states of wireless terminal devices is described. A method aspect of this technique comprises receiving a request for an RRC state transition control for a terminal device, wherein the request includes at least one identifier associated with the terminal device. The method further comprises obtaining a temporal inactivity parameter associated with the at least one identifier, wherein the temporal inactivity parameter depends on an estimated period of time between two traffic activities of the terminal device. Further still, the method comprises triggering, based on the temporal inactivity parameter or a parameter derived on the basis of the temporal inactivity parameter, the RRC state transition control for the terminal device.

摘要： A performance monitoring system and method is based on a Detailed Call Record (DCR). A DCR contains records of events occurring in different network domains (14, 20, 40) that are related to a single, specific VoLTE call. The DCR events for each VoLTE call cover all legs of the call, and for each call leg, the relevant events are ordered by time. A DCR also contains basic information to identify the call: the IMS Charging Identifier (ICID), the International Mobile Subscriber Identity (IMSI) of all involved subscribers, and the start and stop timestamps of the call. A DCR has all the relevant user plane measurement, radio measurement, and control plane data from all the involved domains (14, 20, 40) for all call legs of a VoLTE call, in contrast to prior art systems that focus only on a single subscriber's activities for a given call. The DCR thus provides a complete view of the call, allowing more complete analytics and troubleshooting. Furthermore, the data are collected and assembled automatically, with results available real-time, or with a few seconds delay.

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 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： The present disclosure relates to a first Web server (102, 204, 60, 70) and a second Web server (108, 214, 80, 90), and methods therein for controlling of a robot device over a cloud interface. A hyper-text transfer protocol, HTTP, request for a trajectory between a start position and a goal position is sent (S120, S230, 302, 402) towards the second Web server. One or more calculated trajectories are obtained (S122, 304) based on information as received encoded in the request. A HTTP response is sent (306) towards the first WEB server, comprising one or more calculated trajectories. Executing (S126, S266; 308, 406) of a trajectory at least based said one or more of the received trajectories is performed by the first Web server (102, 204, 60, 70). A scalable robot device control method is thus proposed, which is advantageously uses stored calculated trajectories between start and goal positions, for the robot device.

摘要： A technique for acquiring and correlating session-related information from an Internet Protocol Multimedia Subsystem, IMS, is described. The technique comprises the acquisition of control plane information from control plane signalling tapped at an IMS control entity, the acquisition of user plane information from user plane traffic tapped at an IMS user plane entity, and the acquisition of context information from tapped signalling between the IMS control entity and the IMS user plane entity. The acquired context information permits to correlate the control plane information and the user plane information acquired for a particular session.

摘要： An aspect of the present disclosure is directed to a method for initiating a voice call in a mobile communication network. The method comprises detecting that a user device performs a call attempt of initiating a voice call over the mobile communication network while being wirelessly connected to a WiFi access point, determining at least one call attempt parameter indicative of a situation and/determining or environment in which the call attempt is performed, and deciding, based on a decision criterion, whether the voice call to be initiated shall be forced to be used for training a prediction model. If it is decided that the voice call shall be forced to be used for training the prediction model, the method further comprises initiating the voice call over the WiFi access point as a Voice over WiFi, VoWiFi, call, deriving at least one key performance indicator, KPI, from the performed voice call, and providing the at least one call attempt parameter and the at least one KPI to the prediction model for training the prediction model. If it is decided that the voice call shall not be forced to be used for training the prediction model, the method further comprises deciding, based on the at least one call attempt parameter and by applying the prediction model, whether the voice call shall be performed over the WiFi access point or over a 3rd Generation Partnership Project, 3GPP, radio access network.
