Patent number: 11253998Abstract: 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.Type: GrantFiled: October 4, 2017Date of Patent: February 22, 2022Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Geza Szabo, Attila Báder, Sándor Rácz

Publication number: 20210399952Abstract: Selecting a transport configuration for a data network adapted to transport data traffic belonging to different traffic types. A selecting device determines an actual traffic mix of traffic types and corresponding traffic loads transported on the data network. The device determines, based on the actual traffic mix, multiple future traffic mixes of traffic types and corresponding traffic loads, wherein the future traffic mixes are associated with probability values and classifiable into different future traffic mix classes, each future traffic mix class being associated with a predefined transport configuration capable of handling any future traffic mix falling in that future traffic mix class. The device is configured to aggregate the probability values associated with those future traffic mixes that belong to the same future traffic mix class and to select the transport configuration associated with the highest probability value across the aggregated and non-aggregated probability values.Type: ApplicationFiled: November 12, 2018Publication date: December 23, 2021Inventors: Attila BÁDER, László KOVÁCS, Gábor MAGYAR

Patent number: 10477032Abstract: 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.Type: GrantFiled: August 26, 2016Date of Patent: November 12, 2019Assignee: TELEFONATIEBOLAGET LM ERICSSON (PUBL)Inventors: László Kovács, Attila Báder, Jeno Hajdu, György Szaniszló, Ferenc Szász
