Patent number: 11012133Abstract: In some embodiments, a computing system maintains, in a memory, information on one or more terminal devices, a dictionary of beams and information on a spatial grid. The computing system maps each terminal device to the spatial grid based on up-to-date results of radio measurements and calculates, for each spatial element, a load caused by the one or more terminal devices based on the mapping. The computing system evaluates, for each combination of a beam and a terminal device, a reference signal received power, RSRP, based on results of the radio measurements. The computing system calculates a first map of expected spatial distribution of traffic based on the calculated loads and beam-specific second maps of expected RSRP based on the values of the RSRP. Finally, the computing system causes performing beamforming optimization based on the first map and second maps.Type: GrantFiled: September 11, 2020Date of Patent: May 18, 2021Assignee: NOKIA SOLUTIONS AND NETWORKS OYInventors: Veronique Capdevielle, Afef Feki, Deepak Kumar Nayak, Claudiu Mihailescu, Nidham Ben Rached, Suresh Kalyanasundaram

Publication number: 20080318565Abstract: The invention proposes a method for allowing radio communication transitions between packet and circuit switched modes in a cellular radio communication system comprising a core network, a first radio access network supporting a first mode among packet and circuit switched modes and a second radio access network supporting a second mode among packet and circuit switched modes. The first and second radio access networks include base stations covering respective cells, the base stations being capable of communications with mobile stations, an overlap existing between the cells of the first and second radio access networks, the method comprising the step of detecting and conditionally informing a mobile station, when the mobile station is in communication with a base station of the first radio access network covering a cell overlapping with another cell covered by another base station of the second radio access network.Type: ApplicationFiled: October 6, 2006Publication date: December 25, 2008Applicant: ALCATEL LUCENTInventors: Saso Stojanovski, Claudiu Mihailescu, Pierre Lescuyer
